RESUMO
BACKGROUND: Domestic Violence and Abuse (DVA) is a persistent public health problem in the UK. Healthcare settings offer an opportunity to ask patients about DVA, either opportunistically or in response to the presence of injuries. However, it has been suggested that dental practices and dental teams have not been actively involved supporting adult patients when presenting with injuries that might have resulted from DVA. This qualitative study was conducted to satisfy the evaluative component of the Dentistry Responding in Domestic Violence and Abuse (DRiDVA) feasibility study. METHODS: In total, 30 participants took part in the study; nine associate dentists and practice principals/owners took part in one-to-one interviews and 21 auxiliary staff took part across two focus group discussion sessions. Data were analysed using the seven step Framework Analysis process. RESULT: Three key themes were identified from the data, focusing on barriers to enquiring about domestic violence and abuse, Facilitators of identification and referral of DVA in dental settings, and recommendations for further adaptation of intervention to dental settings. CONCLUSION: DVA training coupled with robust referral pathways to a named specialist DVA advocate increases knowledge and awareness of the signs of DVA and confidence in making onward referrals. Further research is needed to understand how to increase dental professional willingness to ask patients about DVA.

The Pandemic has challenged clinical dentistry globally with the dental education sector seeking alternative training environments. Virtual reality (VR) is gaining recognition as a valuable tool for training dental students and its use by dental schools around the world is growing. The continuous improvement of haptic VR dental trainers provides a platform where irreversible procedures can be safely and unlimitedly practised. This driver has led to the exploration and investment into virtual technology to improve education outcomes in dental students. The aim of this study was to share the early experience of a dental school in the United Kingdom that has initiated the process of embedding haptics into their simulation training within the dental curriculum. This paper explores the process of embedding and operationalising haptic training within the undergraduate curriculum. Using current knowledge of education pedagogy, the school aligned to an evidence-based, best-practice framework which utilised the concept of deliberate practice in the development of the Haptics curriculum which was adaptable and iterative in design. This paper contextualises the implementation of haptic training in a UK dental education setting by providing an outline of the framework used to develop the curriculum. Virtual reality haptics trainers have created unique opportunities and challenges for dental schools. Dental educators have sought to utilise this technology in a structured framework to enhance training.
RESUMO
BACKGROUND: Pathology relating to mandibular wisdom teeth is a frequent presentation to oral and maxillofacial surgeons, and surgical removal of mandibular wisdom teeth is a common operation. The indications for surgical removal of these teeth are alleviation of local pain, swelling and trismus, and also the prevention of spread of infection that may occasionally threaten life. Surgery is commonly associated with short-term postoperative pain, swelling and trismus. Less frequently, infection, dry socket (alveolar osteitis) and trigeminal nerve injuries may occur. This review focuses on the optimal methods in order to improve patient experience and minimise postoperative morbidity. OBJECTIVES: To compare the relative benefits and risks of different techniques for surgical removal of mandibular wisdom teeth. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health Trials Register (to 8 July 2019), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library; 2019, Issue 6), MEDLINE Ovid (1946 to 8 July 2019), and Embase Ovid (1980 to 8 July 2019). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials. We placed no restrictions on the language or date of publication. SELECTION CRITERIA: Randomised controlled trials comparing different surgical techniques for the removal of mandibular wisdom teeth. DATA COLLECTION AND ANALYSIS: Three review authors were involved in assessing the relevance of identified studies, evaluated the risk of bias in included studies and extracted data. We used risk ratios (RRs) for dichotomous data in parallel-group trials (or Peto odds ratios if the event rate was low), odds ratios (ORs) for dichotomous data in cross-over or split-mouth studies, and mean differences (MDs) for continuous data. We took into account the pairing of the split-mouth studies in our analyses, and combined parallel-group and split-mouth studies using the generic inverse-variance method. We used the fixed-effect model for three studies or fewer, and random-effects model for more than three studies. MAIN RESULTS: We included 62 trials with 4643 participants. Several of the trials excluded individuals who were not in excellent health. We assessed 33 of the studies (53%) as being at high risk of bias and 29 as unclear. We report results for our primary outcomes below. Comparisons of different suturing techniques and of drain versus no drain did not report any of our primary outcomes. No studies provided useable data for any of our primary outcomes in relation to coronectomy. There is insufficient evidence to determine whether envelope or triangular flap designs led to more alveolar osteitis (OR 0.33, 95% confidence interval (CI) 0.09 to 1.23; 5 studies; low-certainty evidence), wound infection (OR 0.29, 95% CI 0.04 to 2.06; 2 studies; low-certainty evidence), or permanent altered tongue sensation (Peto OR 4.48, 95% CI 0.07 to 286.49; 1 study; very low-certainty evidence). In terms of other adverse effects, two studies reported wound dehiscence at up to 30 days after surgery, but found no difference in risk between interventions. There is insufficient evidence to determine whether the use of a lingual retractor affected the risk of permanent altered sensation compared to not using one (Peto OR 0.14, 95% CI 0.00 to 6.82; 1 study; very low-certainty evidence). None of our other primary outcomes were reported by studies included in this comparison. There is insufficient evidence to determine whether lingual split with chisel is better than a surgical hand-piece for bone removal in terms of wound infection (OR 1.00, 95% CI 0.31 to 3.21; 1 study; very low-certainty evidence). Alveolar osteitis, permanent altered sensation, and other adverse effects were not reported. There is insufficient evidence to determine whether there is any difference in alveolar osteitis according to irrigation method (mechanical versus manual: RR 0.33, 95% CI 0.01 to 8.09; 1 study) or irrigation volume (high versus low; RR 0.52, 95% CI 0.27 to 1.02; 1 study), or whether there is any difference in postoperative infection according to irrigation method (mechanical versus manual: RR 0.50, 95% CI 0.05 to 5.43; 1 study) or irrigation volume (low versus high; RR 0.17, 95% CI 0.02 to 1.37; 1 study) (all very low-certainty evidence). These studies did not report permanent altered sensation and adverse effects. There is insufficient evidence to determine whether primary or secondary wound closure led to more alveolar osteitis (RR 0.99, 95% CI 0.41 to 2.40; 3 studies; low-certainty evidence), wound infection (RR 4.77, 95% CI 0.24 to 96.34; 1 study; very low-certainty evidence), or adverse effects (bleeding) (RR 0.41, 95% CI 0.11 to 1.47; 1 study; very low-certainty evidence). These studies did not report permanent sensation changes. Placing platelet rich plasma (PRP) or platelet rich fibrin (PRF) in sockets may reduce the incidence of alveolar osteitis (OR 0.39, 95% CI 0.22 to 0.67; 2 studies), but the evidence is of low certainty. Our other primary outcomes were not reported. AUTHORS' CONCLUSIONS: In this 2020 update, we added 27 new studies to the original 35 in the 2014 review. Unfortunately, even with the addition of these studies, we have been unable to draw many meaningful conclusions. The small number of trials evaluating each comparison and reporting our primary outcomes, along with methodological biases in the included trials, means that the body of evidence for each of the nine comparisons evaluated is of low or very low certainty. Participant populations in the trials may not be representative of the general population, or even the population undergoing third molar surgery. Many trials excluded individuals who were not in good health, and several excluded those with active infection or who had deep impactions of their third molars. Consequently, we are unable to make firm recommendations to surgeons to inform their techniques for removal of mandibular third molars. The evidence is uncertain, though we note that there is some limited evidence that placing PRP or PRF in sockets may reduce the incidence of dry socket. The evidence provided in this review may be used as a guide for surgeons when selecting and refining their surgical techniques. Ongoing studies may allow us to provide more definitive conclusions in the future.

HIV TEACHING: A dental curriculum which fosters knowledge and attitude. OBJECTIVES: A pilot study to explore dental students views of current HIV related teaching and to assess the impact of this teaching on the students' self-perceived confidence in delivering dental care to HIV patients. METHODS: A short cross-sectional survey was conducted to gather the views of students on both objectives. Data was collected using an online self-administered questionnaire. Descriptive data analysis was conducted and used to present the data. Additionally, a one to one interview was performed with a past dental student for a thematic analysis. RESULTS: The HIV teaching at this dental school uses different learning approaches involving didactic, reflective, and participatory methods to address the knowledge, attitudinal and skills objectives. A didactic and experiential problem-based approach using role-play with simulated patients with feedback, and discussion is utilised. Preliminary results show dental students perceive the course to be valuable and there is a general improvement in confidence in their knowledge and ability to communicate with HIV-positive patients. CONCLUSIONS: This evaluation suggests the course format and content are appropriate in providing education and training for dental students and supports the value of teaching HIV to undergraduate students.

INTRODUCTION: Dentists have an important role in reducing new HIV infections by early diagnosis and need to know how to treat patients with HIV and understand universal cross-infection control. In many parts of the world, healthcare professionals struggle to provide care because of barriers including stigma and cultural attitudes. AIM: To investigate the effectiveness of a brief educational intervention in understanding/changing the views of dental school deans regarding the quality of the oral health and HIV/AIDS teaching and their willingness to undertake a curriculum review if appropriate. METHODS: Questionnaires before and after interactive presentation to the deans of 30 Indonesian dental schools and discussion. RESULTS: Only six of 30 dental school deans believed that their HIV undergraduate dental student teaching was inadequate before the intervention, but 29 of 30 deans recognised the need to review their curriculum after the intervention. Whilst the majority (24/30) felt that their HIV teaching was adequate, good or excellent, the majority also thought that their students would find it difficult to treat patients with HIV. CONCLUSION: The brief educational intervention was effective in improving the understanding/changing the views of dental school deans regarding the quality of HIV/AIDS teaching and learning at their own institution and engaging a willingness to undertake curriculum review.

BACKGROUND: Implants may be placed penetrating the oral mucosa (1-stage procedure) or can be completely buried under the oral mucosa (2-stage procedure) during the healing phase of the bone at the implant surface. With a 2-stage procedure the risk of having unwanted loading onto the implants is minimized, but a second minor surgical intervention is needed to connect the healing abutments and more time is needed prior to start the prosthetic phase because of the wound-healing period required in relation to the second surgical intervention. OBJECTIVES: To evaluate whether a 1-stage implant placement procedure is as effective as a 2-stage procedure. SEARCH METHODS: The Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE and EMBASE were searched. Handsearching included several dental journals. Authors of all identified trials, an Internet discussion group and 55 dental implant manufacturers were contacted to find unpublished randomised controlled trials (RCTs). The last electronic search was conducted on 21 January 2009. SELECTION CRITERIA: All RCTs of osseointegrated dental implants comparing the same dental implants placed according to 1- versus 2-stage procedures with a minimum follow up of 6 months after loading. Outcome measures were: prosthesis failures, implant failures, marginal bone level changes on intraoral radiographs, patient preference including aesthetics, aesthetics evaluated by dentists, and complications. DATA COLLECTION AND ANALYSIS: Screening of eligible studies, assessment of the methodological quality of the trials and data extraction were conducted in duplicate and independently by two review authors. Authors were contacted for missing information. Results were expressed as random-effects models using mean differences for continuous outcomes and risk ratios for dichotomous outcomes with 95% confidence intervals. MAIN RESULTS: Five RCTs were identified and included reporting data on 239 patients in total. On a patient, rather than per implant basis, the meta-analyses showed no statistically significant differences for prosthesis and implant failures, though trends, especially in fully edentulous patients, favoured 2-stage (submerged) implants. AUTHORS' CONCLUSIONS: The number of patients included in the trials was too small to draw definitive conclusions. The 1-stage approach might be preferable in partially edentulous patients since it avoids one surgical intervention and shortens treatment times, while a 2-stage submerged approach could be indicated when an implant has not obtained an optimal primary stability or when barriers are used for guided tissue regeneration, or when it is expected that removable temporary prostheses could transmit excessive forces on the penetrating abutments especially in fully edentulous patients.

PURPOSE: Validation of platelet-rich plasma (PRP) system and assessing its enhancing effect on the healing of iliac crest grafts before implant placement. MATERIALS AND METHODS: Patients randomly allocated to test (n = 13) and control (n = 9) groups. Iliac crest grafts were mixed with PRP in the test group. Tetracycline labeling preceded implant placement. Bone samples were harvested for histomorphometrical analysis. Platelet and growth factor quantifications were performed. ANALYSIS: Data were analyzed using SPSS software package. Independent t test was used and statistical significance was set at 5%. RESULTS: The PRP group showed significantly higher platelet counts, PDGF-BB, and TGF-ß1 concentrations. Tendency to higher volume of woven bone was observed in the PRP group (13 ± 11 vs 4 ± 6, P = 0.1). Histomorphometry showed increased seam separation in the PRP group (8.8 ± 9 µm vs 1.5 ± 3 µm, P = 0.039). Remodeling activity was higher in PRP-woven bone sections and comparable in trabecular sections. CONCLUSION: PRP significantly increased platelet and growth factor concentrations and was of possible enhancing effect on the rate of bone formation at 3 to 4 months of grafting. The clinical significance of this enhancement is yet to be established.

BACKGROUND: The surgical removal of mandibular wisdom teeth is one of the most common operations undertaken in oral and maxillofacial surgery. The most common indication for surgery is infection about a partially erupted tooth that is impacted against bone or soft tissues. Other indications include unrestorable caries, pulpal and periapical pathology, fracture of the tooth and cyst development, amongst others. Most commonly the benefits of surgical removal of a wisdom tooth include alleviation of the symptoms and signs of pericoronitis and its potential consequences. However, surgery is frequently associated with postoperative pain, swelling and trismus. Less commonly complications include infection, including dry socket, trigeminal nerve injuries and rarely fracture of the mandible. OBJECTIVES: To compare the relative benefits and risks of different techniques for undertaking various aspects or stages of the surgical extraction of mandibular wisdom teeth. SEARCH METHODS: We searched the Cochrane Oral Health Group's Trials Register (to 21 March 2014), CENTRAL (The Cochrane Library 2014, Issue 1), MEDLINE (OVID) (1946 to 21 March 2014) and EMBASE (OVID) (1980 to 21 March 2014). We searched ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform for ongoing trials. There were no restrictions regarding language or date of publication in the electronic searches. SELECTION CRITERIA: RCTs comparing surgical techniques for removal of mandibular wisdom teeth. DATA COLLECTION AND ANALYSIS: Two review authors conducted assessment of relevance, risk of bias and data extraction. Study authors were contacted for additional information. RRs were used for dichotomous data and MDs for continuous data, unless the event rate was very low and Peto ORs were used. The pairing of the split-mouth studies was taken into account in the analysis for both dichotomous and continuous outcomes, and parallel group and split-mouth studies were combined using the generic inverse variance method. Random-effects models were used provided there were more than three studies (fixed-effect models otherwise). MAIN RESULTS: A total of 35 trials (2569 patients) were included. The interventions under consideration fell into seven broad categories, with many comparisons including only a small number of trials. Twenty-one of the trials were assessed at high risk of bias, the remaining 14 as unclear. The results are described in the summary of findings tables.Triangular flaps were associated with a 71% reduction in alveolar osteitis at one week (RR 0.29, 95% CI 0.11 to 0.78; three trials, moderate quality) and reduction in pain at 24 hours (MD -0.21, 95% CI -0.32 to -0.10; two trials, moderate quality) compared with envelope flaps. There was no evidence of a difference in overall infection rates, in maximum mouth opening or in permanent sensation. However, there was some evidence that residual swelling after one week was slightly increased in the triangular flap groups compared to envelope flap types (MD 0.66 mm, 95% CI 0.26 to 1.07; two trials, low quality). We found no data on temporary sensation, or adverse events.There was low quality evidence from two studies, looking at the use of a retractor during third molar surgery, to indicate more cases of temporary altered sensation (up to one month) when a retractor was used (Peto OR 5.19, 95% CI 1.38 to 19.49; two trials, low quality). One study reported that this did not persist for more than six months in either group. We found no data for use of a retractor on other primary outcomes or adverse effects (including fracture of the mandible).Due to the small number of studies, the different comparisons evaluated, the variable outcomes reported and the paucity of useful data for all primary outcomes we were not able to draw any conclusions concerning bone removal in third molar surgery.There was insufficient evidence from single studies of very low quality on irrigation method (manual versus mechanical) or irrigation volume (low or high) to determine whether there were differences or not for the outcomes of alveolar osteitis or postoperative infection. We found no data for any of the other primary outcomes.There was insufficient evidence (low to very low quality) that any wound closure technique (primary versus secondary) was superior to another for the outcomes of alveolar osteitis, postoperative infection or maximum mouth opening achieved after seven days, or reactionary bleeding. There was evidence that secondary wound closure was associated with reduced pain at 24 hours (MD 0.79, 95% CI 0.35 to 1.24; four trials, moderate quality) and slightly reduced swelling after one week (MD 0.33, 95% CI 0.09 to 0.57; seven trials, moderate quality).We found no data on other primary outcomes.There was some evidence that the use of a surgical drain was associated with less postoperative swelling (MD -0.90, 95% CI -1.62 to -0.19; five trials, moderate quality) and greater maximum mouth opening one week after surgery (MD 3.72 mm, 95% CI 2.84 to 4.59; two trials, moderate quality). There was insufficient evidence from a single study (low quality) to determine whether the presence of a drain made any difference to pain at 24 hours postoperation. There were no data for the other primary outcomes.Although two RCTs compared coronectomy with complete extraction, flaws in the design and the unit of analysis of these studies meant that there were no reliable data available for inclusion. AUTHORS' CONCLUSIONS: The thirty-five included trials looked at a range of different surgical techniques. The comparisons related to seven broad aspects of the surgical procedures for impacted mandibular third molars: type of surgical flap raised, use of retractors, techniques for bone removal, wound irrigation, wound closure, wound drainage, and complete/incomplete tooth removal. The quality of the body of evidence for each of these comparisons was very low to moderate due to the small number of trials and patients, and the majority of the trials being at high risk of bias (65%) with the remainder at unclear risk of bias.The evidence for making changes to surgical practice is therefore limited. However, it is useful to describe the state of the research evidence supporting practice so that surgeons can make an informed choice in adopting new techniques, or continuing with established techniques.

BACKGROUND: Iatrogenic injury of the inferior alveolar or lingual nerve or both is a known complication of oral and maxillofacial surgery procedures. Injury to these two branches of the mandibular division of the trigeminal nerve may result in altered sensation associated with the ipsilateral lower lip or tongue or both and may include anaesthesia, paraesthesia, dysaesthesia, hyperalgesia, allodynia, hypoaesthesia and hyperaesthesia. Injury to the lingual nerve may also affect taste perception on the affected side of the tongue. The vast majority (approximately 90%) of these injuries are temporary in nature and resolve within eight weeks. However, if the injury persists beyond six months it is deemed to be permanent. Surgical, medical and psychological techniques have been used as a treatment for such injuries, though at present there is no consensus on the preferred intervention, or the timing of the intervention. OBJECTIVES: To evaluate the effects of different interventions and timings of interventions to treat iatrogenic injury of the inferior alveolar or lingual nerves. SEARCH METHODS: We searched the following electronic databases: the Cochrane Oral Health Group's Trial Register (to 9 October 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2013, Issue 9), MEDLINE via OVID (1946 to 9 October 2013) and EMBASE via OVID (1980 to 9 October 2013). No language restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: Randomised controlled trials (RCTs) involving interventions to treat patients with neurosensory defect of the inferior alveolar or lingual nerve or both as a sequela of iatrogenic injury. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by The Cochrane Collaboration. We performed data extraction and assessment of the risk of bias independently and in duplicate. We contacted authors to clarify the inclusion criteria of the studies. MAIN RESULTS: Two studies assessed as at high risk of bias, reporting data from 26 analysed participants were included in this review. The age range of participants was from 17 to 55 years. Both trials investigated the effectiveness of low-level laser treatment compared to placebo laser therapy on inferior alveolar sensory deficit as a result of iatrogenic injury.Patient-reported altered sensation was partially reported in one study and fully reported in another. Following treatment with laser therapy, there was some evidence of an improvement in the subjective assessment of neurosensory deficit in the lip and chin areas compared to placebo, though the estimates were imprecise: a difference in mean change in neurosensory deficit of the chin of 8.40 cm (95% confidence interval (CI) 3.67 to 13.13) and a difference in mean change in neurosensory deficit of the lip of 21.79 cm (95% CI 5.29 to 38.29). The overall quality of the evidence for this outcome was very low; the outcome data were fully reported in one small study of 13 patients, with differential drop-out in the control group, and patients suffered only partial loss of sensation. No studies reported on the effects of the intervention on the remaining primary outcomes of pain, difficulty eating or speaking or taste. No studies reported on quality of life or adverse events.The overall quality of the evidence was very low as a result of limitations in the conduct and reporting of the studies, indirectness of the evidence and the imprecision of the results. AUTHORS' CONCLUSIONS: There is clearly a need for randomised controlled clinical trials to investigate the effectiveness of surgical, medical and psychological interventions for iatrogenic inferior alveolar and lingual nerve injuries. Primary outcomes of this research should include: patient-focused morbidity measures including altered sensation and pain, pain, quantitative sensory testing and the effects of delayed treatment.

BACKGROUND: Sutures (stitches), staples and adhesive tapes have been used for many years as methods of wound closure, but tissue adhesives have entered clinical practice more recently. Closure of wounds with sutures enables the closure to be meticulous, but the sutures may show tissue reactivity and can require removal. Tissue adhesives offer the advantages of an absence of risk of needlestick injury and no requirement to remove sutures later. Initially, tissue adhesives were used primarily in emergency room settings, but this review looks at the use of tissue adhesives in the operating room/theatre where surgeons are using them increasingly for the closure of surgical skin incisions. OBJECTIVES: To determine the effects of various tissue adhesives compared with conventional skin closure techniques for the closure of surgical wounds. SEARCH METHODS: In March 2014 for this second update we searched the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. We did not restrict the search and study selection with respect to language, date of publication or study setting. SELECTION CRITERIA: Only randomised controlled trials were eligible for inclusion. DATA COLLECTION AND ANALYSIS: We conducted screening of eligible studies, data extraction and risk of bias assessment independently and in duplicate. We expressed results as random-effects models using mean difference for continuous outcomes and risk ratios (RR) with 95% confidence intervals (CI) for dichotomous outcomes. We investigated heterogeneity, including both clinical and methodological factors. MAIN RESULTS: This second update of the review identified 19 additional eligible trials resulting in a total of 33 studies (2793 participants) that met the inclusion criteria. There was low quality evidence that sutures were significantly better than tissue adhesives for reducing the risk of wound breakdown (dehiscence; RR 3.35; 95% CI 1.53 to 7.33; 10 trials, 736 participants that contributed data to the meta-analysis). The number needed to treat for an additional harmful outcome was calculated as 43. For all other outcomes - infection, patient and operator satisfaction and cost - there was no evidence of a difference for either sutures or tissue adhesives. No evidence of differences was found between tissue adhesives and tapes for minimising dehiscence, infection, patients' assessment of cosmetic appearance, patient satisfaction or surgeon satisfaction. However there was evidence in favour of using tape for surgeons' assessment of cosmetic appearance (mean difference (VAS 0 to 100) 9.56 (95% CI 4.74 to 14.37; 2 trials, 139 participants). One trial compared tissue adhesives with a variety of methods of wound closure and found both patients and clinicians were significantly more satisfied with the alternative closure methods than the adhesives. There appeared to be little difference in outcome for different types of tissue adhesives. One study that compared high viscosity with low viscosity adhesives found that high viscosity adhesives were less time-consuming to use than low viscosity tissue adhesives, but the time difference was small. AUTHORS' CONCLUSIONS: Sutures are significantly better than tissue adhesives for minimising dehiscence. In some cases tissue adhesives may be quicker to apply than sutures. Although surgeons may consider the use of tissue adhesives as an alternative to other methods of surgical site closure in the operating theatre, they need to be aware that sutures minimise dehiscence. There is a need for more well designed randomised controlled trials comparing tissue adhesives with alternative methods of closure. These trials should include people whose health may interfere with wound healing and surgical sites of high tension.

BACKGROUND: Pathological speech diagnosis is crucial for identifying and treating various speech disorders. Accurate diagnosis aids in developing targeted intervention strategies, improving patients' communication abilities, and enhancing their overall quality of life. With the rising incidence of speech-related conditions globally, including oral health, the need for efficient and reliable diagnostic tools has become paramount, emphasizing the significance of advanced research in this field. METHODS: This paper introduces novel features for deep learning in the analysis of short voice signals. It proposes the incorporation of time-space and time-frequency features to accurately discern between two distinct groups: Individuals exhibiting normal vocal patterns and those manifesting pathological voice conditions. These advancements aim to enhance the precision and reliability of diagnostic procedures, paving the way for more targeted treatment approaches. RESULTS: Utilizing a publicly available voice database, this study carried out training and validation using long short-term memory (LSTM) networks learning on the combined features, along with a data balancing strategy. The proposed approach yielded promising performance metrics: 90% accuracy, 93% sensitivity, 87% specificity, 88% precision, an F1 score of 0.90, and an area under the receiver operating characteristic curve of 0.96. The results surpassed those obtained by the networks trained using wavelet-time scattering coefficients, as well as several algorithms trained with alternative feature types. CONCLUSIONS: The incorporation of time-frequency and time-space features extracted from short segments of voice signals for LSTM learning demonstrates significant promise as an AI tool for the diagnosis of speech pathology. The proposed approach has the potential to enhance the accuracy and allow for real-time pathological speech assessment, thereby facilitating more targeted and effective therapeutic interventions.

The mandible or lower jaw is the largest and hardest bone in the human facial skeleton. Fractures of the mandible are reported to be a common facial trauma in emergency medicine and gaining insights into mandibular morphology in different facial types can be helpful for trauma treatment. Furthermore, features of the mandible play an important role in forensics and anthropology for identifying gender and individuals. Thus, discovering hidden information of the mandible can benefit interdisciplinary research. Here, for the first time, a method of artificial intelligence-based nonlinear dynamics and network analysis are used for discovering dissimilar and similar radiographic features of mandibles between male and female subjects. Using a public dataset of 10 computed tomography scans of mandibles, the results suggest a difference in the distribution of spatial autocorrelation between genders, uniqueness in network topologies among individuals and shared values in recurrence quantification.
RESUMO
BACKGROUND: Both paracetamol and ibuprofen are commonly used analgesics for the relief of pain following the surgical removal of lower wisdom teeth (third molars). In 2010, a novel analgesic (marketed as Nuromol) containing both paracetamol and ibuprofen in the same tablet was launched in the United Kingdom, this drug has shown promising results to date and we have chosen to also compare the combined drug with the single drugs using this model. In this review we investigated the optimal doses of both paracetamol and ibuprofen via comparison of both and via comparison with the novel combined drug. We have taken into account the side effect profile of the study drugs. This review will help oral surgeons to decide on which analgesic to prescribe following wisdom tooth removal. OBJECTIVES: To compare the beneficial and harmful effects of paracetamol, ibuprofen and the novel combination of both in a single tablet for pain relief following the surgical removal of lower wisdom teeth, at different doses and administered postoperatively. SEARCH METHODS: We searched the Cochrane Oral Health Group'sTrials Register (to 20 May 2013); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2013, Issue 4); MEDLINE via OVID (1946 to 20 May 2013); EMBASE via OVID (1980 to 20 May 2013) and the metaRegister of Controlled Trials (to 20 May 2013). We checked the bibliographies of relevant clinical trials and review articles for further studies. We wrote to authors of the identified randomised controlled trials (RCTs), and searched personal references in an attempt to identify unpublished or ongoing RCTs. No language restriction was applied to the searches of the electronic databases. SELECTION CRITERIA: Only randomised controlled double-blinded clinical trials were included. Cross-over studies were included provided there was a wash out period of at least 14 days. There had to be a direct comparison in the trial of two or more of the trial drugs at any dosage. All trials used the third molar pain model. DATA COLLECTION AND ANALYSIS: All trials identified were scanned independently and in duplicate by two review authors, any disagreements were resolved by discussion, or if necessary a third review author was consulted. The proportion of patients with at least 50% pain relief (based on total pain relief (TOTPAR) and summed pain intensity difference (SPID) data) was calculated for all three drugs at both two and six hours postdosing and meta-analysed for comparison. The proportion of participants using rescue medication over both six and eight hours was also collated and compared. The number of patients experiencing adverse events or the total number of adverse events reported or both were analysed for comparison. MAIN RESULTS: Seven studies were included, they were all parallel-group studies, two studies were assessed as at low risk of bias and three at high risk of bias; two were considered to have unclear bias in their methodology. A total of 2241 participants were enrolled in these trials.Ibuprofen was found to be a superior analgesic to paracetamol at several doses with high quality evidence suggesting that ibuprofen 400 mg is superior to 1000 mg paracetamol based on pain relief (estimated from TOTPAR data) and the use of rescue medication meta-analyses. The risk ratio for at least 50% pain relief (based on TOTPAR) at six hours was 1.47 (95% confidence interval (CI) 1.28 to 1.69; five trials) favouring 400 mg ibuprofen over 1000 mg paracetamol, and the risk ratio for not using rescue medication (also favouring ibuprofen) was 1.50 (95% CI 1.25 to 1.79; four trials).The combined drug showed promising results, with a risk ratio for at least 50% of the maximum pain relief over six hours of 1.77 (95% CI 1.32 to 2.39) (paracetamol 1000 mg and ibuprofen 400 mg) (one trial; moderate quality evidence), and risk ratio not using rescue medication 1.60 (95% CI 1.36 to 1.88) (two trials; moderate quality evidence).The information available regarding adverse events from the studies (including nausea, vomiting, headaches and dizziness) indicated that they were comparable between the treatment groups. However, we could not formally analyse the data as it was not possible to work out how many adverse events there were in total. AUTHORS' CONCLUSIONS: There is high quality evidence that ibuprofen is superior to paracetamol at doses of 200 mg to 512 mg and 600 mg to 1000 mg respectively based on pain relief and use of rescue medication data collected at six hours postoperatively. The majority of this evidence (five out of six trials) compared ibuprofen 400 mg with paracetamol 1000 mg, these are the most frequently prescribed doses in clinical practice. The novel combination drug is showing encouraging results based on the outcomes from two trials when compared to the single drugs.

UNLABELLED: Conscious sedation in dentistry is usually indicated because a patient's anxiety can prohibit the necessary dental treatment being undertaken. It may also be indicated because of unpleasant or lengthy treatment or to prevent exacerbation of a patient's medical or behavioural condition by anxiety. The indicator of sedation need (IOSN) tool has been developed to help support dentists in their clinical decision-making and uses information about a patient's anxiety, medical and behavioural status and treatment complexity. The IOSN has been used to measure sedation need and has shown that 5.1% of patients attending general dental practices have a high need of conscious sedation. IOSN has also been used to investigate the need for conscious sedation in the general population among dental practice attenders and those who don't attend. The proportion was found to be 6.7%. CLINICAL RELEVANCE: Some patients require conscious sedation in order to access dental care. The indicator of sedation need (IOSN) tool helps in the decision-making process.

Patients with facial trauma may suffer from injuries such as broken bones, bleeding, swelling, bruising, lacerations, burns, and deformity in the face. Common causes of facial-bone fractures are the results of road accidents, violence, and sports injuries. Surgery is needed if the trauma patient would be deprived of normal functioning or subject to facial deformity based on findings from radiology. Although the image reading by radiologists is useful for evaluating suspected facial fractures, there are certain challenges in human-based diagnostics. Artificial intelligence (AI) is making a quantum leap in radiology, producing significant improvements of reports and workflows. Here, an updated literature review is presented on the impact of AI in facial trauma with a special reference to fracture detection in radiology. The purpose is to gain insights into the current development and demand for future research in facial trauma. This review also discusses limitations to be overcome and current important issues for investigation in order to make AI applications to the trauma more effective and realistic in practical settings. The publications selected for review were based on their clinical significance, journal metrics, and journal indexing.
RESUMO
BACKGROUND: Adrenal crisis is a life threatening condition which can be induced by stress during surgery in patients with adrenal insufficiency. This may be prevented by perioperative administration of high doses of steroids. There is disagreement on whether supplemental perioperative steroids are required and, when administered, on the amount and frequency of doses. The review was originally published in 2009 and was updated in 2012. OBJECTIVES: To assess whether it is necessary to administer supplemental perioperative steroids in adult patients on maintenance doses of glucocorticoids because of adrenal insufficiency. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 2); MEDLINE (1966 to February 2012); EMBASE (1980 to February 2012); LILACS (1982 to May 2012); and the databases of ongoing trials. We handsearched the Journal of Clinical Endocrinology and Metabolism (1982 to 2008), Clinical Endocrinology (1972 to 2008), Surgery (1948 to 1994), Annals of Surgery (1948 to 1994), and Anaesthesia (1948 to 2001). The original search was performed in January 2009. SELECTION CRITERIA: We included randomized controlled trials that compared the use of supplemental perioperative steroids to placebo in adult patients on maintenance doses of steroids and who required surgery. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data. Study authors were contacted for missing information. We used mean differences and standard deviations to summarize the data for each group. MAIN RESULTS: Two trials involving 37 patients were included. These studies reported that supplemental perioperative steroids were not required during surgery for patients with adrenal insufficiency. Neither study reported any adverse effects or complications in the intervention and control groups. Both studies were graded as having a high risk of bias. AUTHORS' CONCLUSIONS: Owing to the small number of patients, the results may not be representative. Based on current available evidence, we are unable to support or refute the use of supplemental perioperative steroids for patients with adrenal insufficiency during surgery.

The Institute of Dentistry at Barts and The School of Medicine and Dentistry, Queen Mary University of London, has seen much change since 1857 when surgeon dentist, H. J. Barrett, was appointed to The London to oversee the extraction of teeth. However, the mission remains the same: provision of excellent patient care through our education and research to improve the oral health and general health of our local population, but also with global impact.The Institute of Dentistry is embedded in a fundamentally multidisciplinary environment of the wider university and this is reflected in our research activity. The available complementary skills in cell and molecular biology, microbiology, materials science, chemistry, biophysics, clinical science and population health allows us to undertake basic science research, patient- and population-based research and clinical biometric research.Our Centre for Teaching and Innovation is a catalyst for educational research, including that related to new technologies and the expansion of e-learning, to ultimately inform local practice and the experience of our students.

Introduction: Coronavirus disease (COVID-19) was declared a global pandemic on 11 March 2020, and all routine dental care in England was suspended on 25 March 2020. Oral surgeons typically continued their roles due to the requirement of surgical expertise in the management of urgent care. Aims: To survey the British Association of Oral Surgeons' membership of 654 exploring the impact and response of the speciality in the early phase of the pandemic. Methods: British Association of Oral Surgeons members were invited to participate in a weekly online survey commencing 30th March 2020 for 4 weeks. Themes explored included demographics, Personal Protective Equipment (PPE), clinical role and care provided, and financial impact. Results: 400 responses were received over the 4-week period. Telephone advice was rapidly introduced ahead of clinical examinations. Few oral surgeons were initially able to provide emergency oral surgery procedures or clinical examinations due to PPE shortage. Only a small proportion of oral surgeons were required themselves to isolate and only a small proportion were redeployed. Conclusion: The COVID-19 pandemic severely disrupted UK oral surgery services particularly in the early stage and highlight the lack of preparedness. As availability of PPE and evidence on aerosol-generating procedures and infection control became more readily accessible, surgeons became more confident to provide emergency surgical treatment rather than just phone consultations. The impact on patients' oral health is likely to have been profound.
RESUMO
Objectives Assess the feasibility of using the Identification and Referral to Improve Safety (IRIS) intervention in a general dental practice setting and evaluating it using a cluster randomised trial design. IRIS is currently used in general medical practices to aid recognition and support referral into specialist support of adults presenting with injuries and other presenting factors that might have resulted from domestic violence and abuse. Also, to explore the feasibility of a cluster randomised trial design to evaluate the adapted IRIS.Design Feasibility study for a cluster randomised trial of a practice-based intervention.Setting Greater Manchester general dental practices.Results It was feasible to adapt the IRIS intervention used in general medical practices to general dental practices in terms of training the clinical team and establishing a direct referral pathway to a designated advocate educator. General dental practices were keen to adopt the intervention, discuss with patients when presented with the opportunity and utilise the referral pathway. However, we could not use practice IT software prompts and data collection as for general practitioners because there is no unified dental IT system and because coding in dentistry for diagnoses, procedures and outcomes is not developed in the UK.Conclusion While it was feasible to adapt elements of the IRIS intervention to general dental practice and there was general acceptability, we did not have enough empirical data to plan a definitive cluster randomised trial design to evaluate the IRIS-dentistry intervention within general dental practices.
