RESUMO

The 2020 International Association of Dental Traumatology (IADT) Guidelines feature several important changes in the treatment recommendations for traumatic dental injuries (TDIs) from the previous 2012 iteration of these Guidelines. This evidence-based narrative review aims to provide a detailed appraisal of five specific changes incorporated in the 2020 IADT Guidelines, based on the available literature evidence that may have prompted these changes. The paper discusses three excellent additions/changes to the new Guidelines: (i) inclusion of a core outcome set for reporting TDIs; (ii) more conservative management of primary dentition TDIs including the changed recommendations for radiation exposure and managing primary dentition luxation injuries; and (iii) the changes in the treatment recommendations for permanent dentition avulsion injuries. The paper further debates whether two other changes made in the current IADT Guidelines for-(i) intrusion injuries in immature teeth; and (ii) complicated crown-root fractures in mature teeth-have sufficient evidence to support the changed recommendations.

RESUMO

BACKGROUND/AIM: Tooth auto-transplantation has recently gained high clinical acceptance. The aim of this study was to identify the top 100 most-cited articles regarding tooth auto-transplantation, to analyse multiple citations and publication metrics and to outline the historical scientific advancements in this field. MATERIALS AND METHODS: An advanced search of the Clarivate Analytics' Web of Science 'Core Collection' and Elsevier's Scopus databases utilising specific keywords related to tooth auto-transplantation between 1971 and 2021 was performed. The retrieved articles were ranked in descending order based on their Web of Science citation counts and further cross-matched with citation data from Scopus. The extracted data included citation counts, citation density, level of evidence, year of publication, contributing authors names and institutes, corresponding author's address, journal of publication, journal local citations index, cumulative growth index, keywords and keywords Plus. Data analysis was performed using descriptive statistics and graphical mapping. RESULTS: A total of 1290 articles were retrieved. The top 100 most-cited articles received a total of 4899 (Web of Science) and 5250 (Scopus) citations. Among these, cohort studies (29%) and case series (18%) were the most common study designs. Scandinavian countries produced major contributions in defining the top 100 most-cited articles and ranked within the top 5 countries based on the number of publications and citations per year. The greatest contributing authors were Schwartz O (n = 12), Andreasen JO (n = 8) and Paulsen HU (n = 6), and they were affiliated with Copenhagen, Denmark. The top contributing journals were American Journal of Orthodontics and Dentofacial Orthopedics, International Journal of Oral and Maxillofacial Surgery, Oral Surgery Oral Medicine Oral Pathology Oral Radiology, European Journal of Orthodontics, Dental Traumatology and Journal of Oral and Maxillofacial Surgery. CONCLUSION: This bibliometric analysis revealed a large geographical scientific interest and broad development in the field of tooth auto-transplantation spanning multiple dental disciplines.

RESUMO

Tooth autotransplantation is a versatile procedure with several clinical applications among patients across different age groups. The success of this procedure depends on multiple factors. Despite the wealth of studies available, no single primary study or systematic review is able to report on every factor affecting the outcomes of autotransplantation. The aims of this umbrella review were to evaluate treatment-related and patient-related outcomes of autotransplantation and to assess the pre-, peri- or post-operative factors that could affect these. An umbrella review was conducted according to the PRISMA statement. A literature search of five databases was performed up to 25 September 2022. Systematic Reviews (SR) with and without meta-analysis evaluating autotransplantation were included. Calibration among reviewers was carried out prior to study selection, data extraction and Risk of Bias (RoB) assessment. Study overlap was calculated using corrected covered area. Meta-meta-analysis (MMA) was performed for suitable SRs. The AMSTAR 2 critical appraisal tool was used to evaluate the quality of evidence. Seventeen SRs met the inclusion criteria. Only two SRs were suitable for conduct of MMA on autotransplantation of open apex teeth. The 5-year and 10-year survival rates were >95%. A narrative summary on factors that could affect autotransplantation outcomes and comparisons of autotransplantation to other treatment options were reported. Five SRs were rated as 'low quality' and 12 SRs were rated as 'critically low quality' in the AMSTAR 2 RoB assessment. In order to facilitate a more homogenous pool of data for subsequent meta-analysis, an Autotransplantation Outcome Index was also proposed to standardise the definition of outcomes. Autotransplantation of teeth with open apices have a high survival rate. Future studies should standardise the reporting of clinical and radiographic findings, as well as the definition of outcomes.

RESUMO

BACKGROUND: Preformed metal crowns (PMCs) have been used to restore carious primary molars and have a high success and survival rate. There are two methods currently employed for PMC placement - the conventional technique (CT) and Hall technique (HT). AIM: This systematic review aims to compare the outcomes of PMCs placed using the CT and HT. DESIGN: This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. A literature search of five databases was performed up to 23 August 2022. Clinical studies comparing carious primary molars restored with PMCs using either technique with a minimum 12-month follow-up were included. Risk of bias (RoB) assessment was performed using the National Institutes of Health Quality Assessment tool. RESULTS: Five articles met the inclusion criteria, and four were included for meta-analysis. The 12- and 24-month success and survival rates were above 85% for both groups, with no significant differences shown at 12 and 24 months. The HT requires a shorter treatment duration, is more cost-effective and has a high level of acceptability among parents when compared to the CT. Four articles were rated fair, and one article was rated good in the RoB assessment. CONCLUSION: Greater consideration may be given towards using the HT as part of standard treatment procedures in managing carious primary molars. Future studies should standardise reporting of outcomes to facilitate a more homogeneous pool of data for future meta-analysis.

RESUMO

Despite the recent growing evidence in support of prefabricated zirconia crown use as a successful option in managing grossly carious anterior and posterior primary teeth, the use of such crowns remains controversial within the paediatric dental profession. This study aims to assess the use of aesthetic full coverage paediatric restorations among paediatric dentists worldwide, with emphasis on aesthetic prefabricated zirconia crowns. This was an online cross-sectional survey questionnaire study comprising of 38 multiple-choice questions disseminated worldwide through the contact lists of national, regional and international paediatric dental organisations and social media platforms. The survey was completed by 556 respondents thus achieving power, with 391 (70.3%) females and 165 (29.7%) males. The respondents were from 55 different countries spread across six continents. The use of aesthetic full coverage restorations was reported by 80% (n = 444) of the respondents. For restoring anterior teeth, participants mainly used either composite strip crowns (94.4%, n = 419) or zirconia crowns (73.6%, n = 327), while those who used aesthetic crowns for restoring posterior teeth mainly used zirconia crowns (68.2%, n = 303). Within the limitations of this study, the results have shown a wide use of full coverage aesthetic restorations, including the use of zirconia crowns, of primary teeth within this international sample of practicing dentists.

RESUMO

BACKGROUND: Traumatic dental injuries involving the pulp are quite common and there is a need to evaluate the quality of evidence on the success of vital pulp treatment (VPT) interventions in traumatised permanent teeth. OBJECTIVES: The aim of this systematic review was to assess the success of VPT in the management of traumatised human vital permanent teeth diagnosed with complicated crown or crown-root fractures. METHODS: An electronic search of the following databases: Web of Science, Scopus, PubMed, MEDLINE, EMBASE, LILACS, Clinical Trial Registries and the grey literature was performed until 25th /8/2021. Controlled clinical trials, cohort studies, case-control studies, case series with at least five cases and a minimum of 12-months follow-up were included. Non-English language literature was excluded. Two independent assessors performed study selection, data extraction and quality assessment using the National Institutes of Health's quality assessment tool. Disagreements were resolved through consensus/with a third assessor. RESULTS: A total of 14-studies (2-controlled clinical trials, 1-case-control, and 11-case series) published between 1978-2020, with a total of 1081 permanent teeth and an age range between 6-42 years-old were included. Bias analysis ranged considerably from 'good' to 'poor'. Meta-analysis was not performed due to data heterogeneity, unclear reporting, and limited number of controlled clinical studies. Partial pulpotomy was the main reported clinical procedure with an overall success rate between 82.9-100%. Complete pulpotomy and direct pulp capping were associated with lower success rates of 79.4-85.7% and 19.5%, respectively. Calcium hydroxide was the main pulp capping material with favourable clinical and radiographic success (79.4-100%). Biodentine® , mineral trioxide aggregate and IRoot® BP were also associated with a high clinical and radiographic success, 80-91%, 80-100%, and 90-100%, respectively, albeit in fewer studies. DISCUSSION: Although a high success rate has been reported when using VPT in managing pulpally involved traumatised teeth, the results of this systematic review clearly highlighted a paucity and low quality of the available evidence. CONCLUSIONS: Overall high success of VPT in the management of traumatised vital permanent teeth were reported, although based on limited evidence of well-conducted clinical studies. REGISTRATION: PROSPERO database (CRD42020205213).

RESUMO

BACKGROUND/AIM: The knowledge of standardized care guidelines is critical to the confidence of practitioners in managing dental trauma. Therefore, the aim of this study was to assess the awareness, use and impact of the International Association of Dental Traumatology guidelines, and the online Dental Trauma Guide on general dental practitioners' self-reported confidence and knowledge in managing traumatic dental injuries in the primary and permanent dentitions. MATERIALS AND METHODS: A cross-sectional, pre-piloted, 27-item self-administered questionnaire survey was distributed electronically to general dental practitioners' working within five member states of the Gulf Cooperation Council countries (Kingdom of Bahrain, Kingdom of Saudi Arabia, Kuwait, Oman, and Qatar) between September and December 2020. Data were collected and analysed using descriptive statistics and Wilcoxon Signed Rank test analysis for relevant comparisons. RESULTS: A total of 294 respondents completed the survey, with the majority being from the Kingdom of Saudi Arabia (47.4%) and Qatar (27.3%). A lack of evidence-based knowledge in managing traumatic dental injuries was evident among more than half of the respondents. Respondents who were cognizant of the recent International Association of Dental Traumatology guidelines (2020) and those who use the Dental Trauma Guide routinely demonstrated a higher self-reported confidence level in managing both simple and complex primary dentition trauma, as well as simple traumatic dental injuries in the permanent dentition (p < .05). CONCLUSION: This survey highlights critical deficiencies in the knowledge of a large number of the respondents in the management of dental trauma which is likely to cause irreversible long-term patient effects.

RESUMO

Dental trauma is common in the UK, with more than one in ten children having experienced some form of dental trauma. In addition, one in ten patients have been reported to have experienced dental trauma before orthodontic treatment. A recent survey of orthodontists' knowledge and experience of orthodontic management of traumatised teeth has highlighted large inconsistencies in management of traumatised teeth among UK orthodontists, highlighting the need for further information or training on orthodontic management of traumatised teeth.Therefore, the following guidelines have been developed in order to provide an evidence-based approach to treat this cohort of patients. The following guidance is based on the available literature, expert opinion and UK orthodontists' consensus drawn from a recent survey.

RESUMO

INTRODUCTION: The quality assurance of undergraduate dental education in the UK is regulated by the General Dental Council who describe the competencies expected of the newly qualified dentist or "safe beginner." Whilst the literature has explored the level of undergraduate training in a number of dental specialties within the UK, there is a paucity of information on the UK curriculum for undergraduate paediatric dental teaching. AIMS: This study aimed to assess the undergraduate teaching of paediatric dentistry within dental schools in the UK. METHODS: An anonymous questionnaire was distributed to all 16 UK dental schools via email. RESULTS: Twelve questionnaires were completed, giving a response rate of 75%. First exposure to both academic teaching and clinical teaching in paediatric dentistry ranged from years 1-4. Whilst there were broad similarities between units with regard to core components of the curricula, there were notable differences including the teaching of regenerative endodontics (75%) and the use of the titanium trauma splint (58%). Silver diamine fluoride was only used clinically in one unit (8%), and non-vital pulpotomy was taught by two units (16%). There was also considerable heterogeneity in assessment methods between universities. CONCLUSION: The undergraduate paediatric dental curriculum is broadly similar between UK dental schools. However, there are discrepancies in assessment methods and the teaching of new advances.

RESUMO

BACKGROUND: Traumatic dental injuries are common. One of the most severe injuries is when a permanent tooth is knocked completely out of the mouth (avulsed). In most circumstances the tooth should be replanted as quickly as possible. There is uncertainty on which interventions will maximise the survival and repair of the replanted tooth. This is an update of a Cochrane Review first published in 2010. OBJECTIVES: To compare the effects of a range of interventions for managing traumatised permanent front teeth with avulsion injuries. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 8 March 2018), Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 2) in the Cochrane Library (searched 8 March 2018), MEDLINE Ovid (1946 to 8 March 2018), and Embase Ovid (1980 to 8 March 2018). The US National Institutes of Health Ongoing Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: We considered randomised and quasi-randomised controlled trials that included a minimum follow-up period of 12 months, for interventions for avulsed and replanted permanent front teeth. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies, extracted data and assessed the risk of bias. Authors were contacted where further information about their study was required. MAIN RESULTS: Four studies, involving a total of 183 participants and 257 teeth were identified. Each of the interventions aimed to reduce infection or alter the inflammatory response or both at the time of or shortly after the tooth or teeth were replanted. Each study assessed a different intervention and therefore it was not appropriate or possible to numerically synthesise the data. All evidence was rated as being of very low quality due to problems with risk of bias and imprecision of results. This means that we are very uncertain about all of the results presented in this review.One study at high risk of bias with 69 participants (138 teeth) compared a 20-minute soak with gentamycin sulphate for both groups prior to replantation with the experimental group receiving daily hyperbaric oxygen for 80 minutes for the first 10 days. There was some evidence of a benefit for the hyperbaric oxygen group in respect of periodontal healing, tooth survival, and pulpal healing.One study at unclear risk of bias with 22 participants (27 teeth) compared the use of two root canal medicaments, Ledermix and Ultracal. There was insufficient evidence of a difference for periodontal healing or tooth survival. This was the only study to formally report adverse events with none identified. Study authors reported that Ledermix caused a greater level of patient dissatisfaction with the colour of avulsed and replanted teeth.A third study at high risk of bias with 19 participants compared extra- or intra-oral endodontics for avulsed teeth which were stored dry for longer than 60 minutes before replantation. There was insufficient evidence of a difference in periodontal healing.The fourth study at high risk of bias with 73 participants compared a 10-minute soak in either thymosin alpha 1 or saline before replantation followed by daily gingival injections with these same medicaments for the first 7 days. There was some evidence of a benefit for thymosin alpha 1 with respect to periodontal healing and tooth survival. AUTHORS' CONCLUSIONS: Based on the results of the included studies, there is insufficient evidence to support or refute the effectiveness of different interventions for avulsed and replanted permanent front teeth. The overall quality of existing evidence was very low, and therefore great caution should be exercised when generalising the results of the included trials. There is urgent need for further well-designed randomised controlled trials.

RESUMO

BACKGROUND/AIM: There is a lack of research into orthodontic movement and management strategies of traumatized teeth. The aim of this survey was to assess the knowledge of UK-based orthodontists in the orthodontic management of traumatized teeth. MATERIALS/METHODS: A 24-item questionnaire survey was electronically distributed to all members of the British Orthodontic Society. RESULTS: A total of 213 respondents completed the survey with the majority of these being UK registered specialists in orthodontics. Three responses were excluded as one was not based within the UK and two were orthodontic trainees with <1 year of experience, leaving a total of 210 respondents. The majority had orthodontically treated up to three patients with a history of dental trauma in the preceding 3 months. Obtaining a trauma history was done by the majority of respondents. A wide variation in times waited by respondents before orthodontically treating teeth with different types of traumatic injuries was observed. Similarly, the preferred orthodontic management strategies of traumatized teeth differed substantially among respondents. Almost all respondents were interested in further training in the management of dental trauma. CONCLUSIONS: The study showed a wide variation in the orthodontic management of traumatized teeth among UK-based orthodontists. Further training and national guideline establishment are indicated for orthodontic management of traumatized teeth in the UK.

RESUMO

BACKGROUND/AIM: Pulp necrosis is a frequent complication following dental trauma. The diagnosis of the state of the dental pulp can be challenging as most commonly used diagnostic tools are subjective and rely on a response from the patient, potentially making their use unreliable, especially in the child population. The aim of the study was to systematically review the evidence on the use of laser Doppler flowmetry in the assessment of the pulp status of permanent teeth compared to other sensibility and/or vitality tests. METHODS: A systematic literature search, using MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, www.clinicaltrials.gov and www.controlled-trials.com, in addition to citation and manual reference list searches, was conducted up to 15th January 2018. A risk of bias assessment was performed using the quality assessment for diagnostic accuracy studies tool (QUADAS-2) with all steps performed independently by two reviewers. RESULTS: Four studies with a high risk of bias were included in the final analysis. Laser Doppler flowmetry was reported to be more accurate in differentiating between teeth with normal pulps and pulp necrosis with a sensitivity of (81.8%-100%) and specificity of 100% in comparison to other vitality tests such as pulp oximetry (sensitivity = 81.3%, specificity = 94.9%) and sensibility tests such as electric pulp testing (sensitivity = 63.3%-91.5%, specificity = 88%-100%). CONCLUSION: Despite the higher reported sensitivity and specificity of laser Doppler flowmetry in assessing pulp blood flow, these data are based on studies with a high level of bias and serious shortfalls in study designs. More research is needed to study the effect of different laser Doppler flowmetry's parameters on its diagnostic accuracy and the true cut-off ratios over which a tooth could be diagnosed as having a normal pulp.

RESUMO

Management of non-vital immature permanent teeth in children remains a challenge in paediatric dentistry. The resulting short roots, thin root dentinal walls, and compromised crown root ratios, not only affect the long-term survival of these teeth but also complicate any intended orthodontic treatment. This case report shows a successful orthodontic movement of a traumatised non-vital immature tooth treated using regenerative endodontics.

RESUMO

Simulation training for invasive dental procedures is a core component of the pre-clinical dental curriculum. Besides conventional mannequin-based simulators, dental schools are now incorporating haptic virtual reality simulation (HVRS) devices to facilitate the transition of students from the simulated dental learning environment to the clinical settings. This study aimed to assess student performance and perceptions of HVRS training as a pedagogical tool in pre-clinical paediatric dentistry. After practicing the primary molar pulpotomy procedure on plastic teeth, participants were randomized into test and control groups. Test group students performed the same procedure on a HVRS device, namely the SIMtoCARE Dente®. Subsequently, both the test and control group students attended another conventional pulpotomy simulation session where the quality of their access outline and pulp chamber deroofing steps were evaluated on plastic teeth. After the control group students also experienced the HVRS, all study participants completed a perception questionnaire on their experience. No significant differences were found between the study and control group students for the quantitative parameters assessed. Although the students regarded HVRS to be a useful adjunct to support their pre-clinical training, an overwhelming majority of the students did not consider HVRS to be a replacement for conventional pre-clinical simulation training.

RESUMO

BACKGROUND: Molar incisor hypomineralisation (MIH) is a common disorder of tooth development, which has recently been found to be associated with a higher prevalence of hypodontia. The aim of this international multicentre study is to determine the association between MIH and other developmental anomalies in different populations. METHODS: Investigators were trained and calibrated for the assessment of MIH and dental anomalies and ethical approvals obtained in each participating country. The study aimed to recruit 584 children with MIH and 584 children without MIH. Patients aged 7-16 years who attend specialist clinics will be invited to participate. Children will undergo a clinical examination to determine the presence and severity of MIH, using an established index. The presence of any other anomalies, affecting tooth number, morphology, or position, will be documented. Panoramic radiographs will be assessed for dental anomalies and the presence of third permanent molars. Statistical analysis, using a chi squared test and regression analysis, will be performed to determine any differences in dental anomaly prevalence between the MIH and non-MIH group and to determine any association between dental anomalies and patient characteristics. CONCLUSION: This large-scale study has the potential to improve understanding about MIH with benefits for patient management.

RESUMO

A 13-year-old female patient with Noonan's syndrome, intra-oral periodontitis, and associated periodontal lesions is presented in this case report. The patient suffered early onset severe molar pattern periodontitis and recurrent intra-oral inflammatory lesions, pyogenic granuloma, and plasmacytosis, which were excised and controlled using a strict oral hygiene protocol based on long-term use of chlorhexidine-based products as auxiliary aid to regular home care and brushing.

RESUMO

Implementing the principles of tissue engineering within the clinical management of non-vital immature permanent teeth is of clinical interest. However, the ideal scaffold remains elusive. The aim of this work was to assess the feasibility of decellularising rat dental pulp tissue and evaluate the ability of such scaffold to support stem cell repopulation. Rat dental pulps were retrieved and divided into control and decellularised groups. The decellularisation protocol incorporated a low detergent concentration and hypotonic buffers. After decellularisation, the scaffolds were characterised histologically, immunohistochemistry and the residual DNA content quantified. Surface topography was also viewed under scanning electron microscopy. Biocompatibility was evaluated using cytotoxicity assays utilising L-929 cell line. Decellularised scaffolds were recellularised with human dental pulp stem cells up to 14 days in vitro. Cellular viability was assessed using LIVE/DEAD stain kit and the recellularised scaffolds were further assessed histologically and immunolabelled using makers for odontoblastic differentiation, cytoskeleton components and growth factors. Analysis of the decellularised scaffolds revealed an acellular matrix with histological preservation of structural components. Decellularised scaffolds were biocompatible and able to support stem cell survival following recellularisation. Immunolabelling of the recellularised scaffolds demonstrated positive cellular expression against the tested markers in culture. This study has demonstrated the feasibility of developing a biocompatible decellularised dental pulp scaffold, which is able to support dental pulp stem cell repopulation. Clinically, decellularised pulp tissue could possibly be a suitable scaffold for use within regenerative (reparative) endodontic techniques.

RESUMO

Background The Hall technique (HT) is popular with UK paediatric dentists (PDs). Global PDs perception/use of HT is unknown.Aim To investigate global PDs opinions/use of HT.Materials and methods A cross-sectional questionnaire of 26 questions was sent to specialist PDs across the globe.Results Responses of 709 PDs from six continents were obtained. The majority (n = 654, 92.32%) had heard about HT but only 50.6% (n = 358) used it, with wide country variations. Respectively, 37.5%, 31.5% and 31% were neutral, against or supportive of HT when they initially heard about it. Only 17% of HT users said it was always the treatment of choice for non-pulpal asymptomatic carious primary molars (NPACPMs), 62% would take a pre-operative radiograph, 65% would consider using high speed drills before HT, 63% would never consider HT under general anaesthesia, 56% would use HT under N2O sedation. Finally, in a clinical scenario of a NPACPM in a cooperative 6-year-old, 75% of PDs would choose conventional restorative methods over the HT.Conclusion The HT is recognised, but not used, by an outright majority of PDs across the globe. Identifiable barriers such as lack of training, perception as substandard dentistry and perceived lack of evidence reduced its use.

RESUMO

Introduction Child abuse and neglect present a significant global concern, therefore, it is imperative that dental professionals can identify children at risk. Previous literature has suggested that general dental practitioners (GDPs) do not feel adequately trained to do so and that there is a gap between the suspicion of abuse and onward referral.Aims To assess the experience of paediatric safeguarding reporting among GDPs in Greater Manchester and investigate the current barriers to reporting safeguarding concerns.Methods An anonymous questionnaire was distributed via email to a sample of general dental practices in Greater Manchester.Results Thirty-six questionnaires were completed, giving a 36% response rate. Fifty-eight percent of respondents had received undergraduate training and 83% had received postgraduate training. Eighty-one percent felt that GDPs require further training and support. Fifty-eight percent of GDPs had been suspicious of at least one case of child abuse or neglect, however, only 28% had completed an onwards referral. Common barriers to reporting included: fear of violence to the child; lack of certainty of diagnosis; and lack of confidence in their suspicions.Conclusion Barriers to the referral of suspected cases of abuse or neglect are still commonly reported. There is a strong demand for further child protection training among GDPs.
