An ambulatory dental treatment of a child with Rett syndrome and limited mouth opening under muscle relaxant-free general anesthesia: a case report.

BACKGROUND: Rett Syndrome (RTT) is a rare, severe, and progressive developmental disorder with intellectual disability. Anesthesia in RTT patients presents a range of challenges. We report a child with RTT who received dental treatment under muscle relaxant-free general anesthesia in our ambulatory center. CASE PRESENTATION: A 15-year-old girl with RTT was admitted to our dental clinic with multiple dental caries and residual roots. Dental treatment was scheduled under ambulatory general anesthesia. After anesthesia induction, a nasal tube was initiated under the guidance of a fiberoptic bronchoscope. Multimodal analgesia, body temperature monitoring, and postoperative nausea and vomiting prevention were applied. No muscle relaxants were used throughout the process. The endotracheal tube was successfully removed after the operation and the patient was discharged home the same day. CONCLUSION: An individualized anesthesia strategy enabled a quick and safe recovery for this RTT patient after dental treatment under muscle relaxant-free general anesthesia.

Dental treatments in patients with special needs provided by university medical center in Southern Taiwan: a retrospective study.

OBJECTIVES: We perform special-need dental treatment at outpatient department (OPD), under general anesthesia (GA) when necessary, and provide domiciliary dental care. We aim to evaluate the profile and the characteristics of special needs patients (SNPs). MATERIALS AND METHODS: We consecutively enrolled 3117 SNPs from January 1, 2019 to December 31, 2022. Eighty patients with rare or genetic diseases were excluded. Demographic data were retrospectively collected. RESULTS: There were totally 3037 SNPs (mean age: 48.2 years; range, 1-100; male-to-female ratio, 1.5); 89.1% (n = 2705) SNPs received dental care at the OPD (OPD-SNPs), 7.9% (n = 239) received dental treatment under GA, and 3.0% (n = 93) received domiciliary dental care. Among those SNPs who received dental treatment under GA (n = 239), 91.2% (n = 218) were mental/intellectual disabled, and most underwent cavity filling (69.5%) and dental extractions (56.5%). OPD-SNPs with mental/intellectual disabilities (n = 1340) received significantly more items of dental treatment than those without (n = 1365). SNPs with more severe disabilities received more fluoride application and ultrasonic scaling (both p < 0.001, trend tests). Interestingly, among OPD-SNPs with mental/intellectual disabilities (n = 1340), more severe patients received more fluoride application (p < 0.001) and ultrasonic scaling (p < 0.001) but fewer root canal treatment (p = 0.007, trend test). CONCLUSIONS: GA benefited SNPs with more dental procedures, including invasive items. SNPs with mental/intellectual disabilities can tolerate more measures and SNPs with more severe mental/intellectual disabilities received more preventive measures but less invasive measures. Similarly, more severe SNPs with other disabilities received more preventive measures but not invasive measures. CLINICAL RELEVANCE: Our findings may provide useful information for special needs dentists and for doctor-patient communication.

Dental abnormalities in rare genetic bone diseases: Literature review.

Currently, over 500 rare genetic bone disorders are identified. These diseases are often accompanied by dental abnormalities, which are sometimes the first clue for an early diagnosis. However, not many dentists are sufficiently familiar with phenotypic abnormalities and treatment approaches when they encounter patients with rare diseases. Such patients often need dental treatment but have difficulties in finding a dentist who can treat them appropriately. Herein we focus on major dental phenotypes and summarize their potential causes and mechanisms, if known. We discuss representative diseases, dental treatments, and their effect on the oral health of patients and on oral health-related quality of life. This review can serve as a starting point for dentists to contribute to early diagnosis and further investigate the best treatment options for patients with rare disorders, with the goal of optimizing treatment outcomes.

A prospective cohort study on factors related to dental care and continuation of care for older adults receiving home medical care.

Information on the effects of dental treatment must be identified and factors that hinder the continuation of dental treatment must be identified to provide appropriate domiciliary dental care (DDC). This study aimed to clarify the treatment outcomes of DDC for older adults and the factors that impede the continuation of such care. This prospective study was conducted at a Japanese clinic specializing in dental care for older adults. The functional status, nutritional status, oral assessment, details of the dental treatment, and outcomes after 6 months of older adults receiving DDC were surveyed. The Oral Health Assessment Tool (OHAT) was used for oral assessment. Cox proportional hazards analysis was used to analyze the factors at the first visit that were associated with treatment continuation. A total of 72 participants (mean age, 85.8 ± 6.9) were included. Twenty-three participants (31.9%) could not continue treatment after 6 months. The most frequently performed procedures were oral care and dysphagia rehabilitation, followed by prosthetic treatment, then tooth extraction. The percentage of participants with teeth that required extraction after 6 months and the total OHAT score decreased significantly. The Barthel Index, Mini Nutritional Assessment Short-Form, and rinsing ability were significantly associated with treatment continuation. Furthermore, instrumental activities of daily living (ADL) and the OHAT "tongue" sub-item were correlated with treatment continuation. In conclusion, DDC improved the oral health status of older adults after 6 months. Factors that impeded treatment continuation were decreased ADL, decreased nutritional status, difficulty in rinsing, and changes in the tongue such as tongue coating.

Estimated compared with actual plans of paediatric dental treatment performed under deep sedation: A retrospective cohort study.

BACKGROUND: Planning the extent of paediatric dental treatment under deep sedation is highly important, as the duration of the sedation should be limited to approximately 1 h, and the amount of local anesthesia is limited by the children's body weight. AIM: To compare treatment plans estimated at initial examinations with actual dental treatments under intravenous deep sedation. We examined factors that could affect the differences. DESIGN: For this retrospective cohort study, data were collected from the medical records of all the children younger than 18 years who underwent dental treatment under intravenous deep sedation during 2019-2021 at the Department of Pediatric Dentistry. RESULTS: In total, 108 children were included. During the actual versus the estimated treatment under deep sedation, more teeth were treated (p < .001), and the treatment was more complex (p < .001). A longer waiting period for dental treatment was found to be correlated with a greater number of treated teeth than was estimated (p = .003) and with greater complexity of the actual than the estimated treatment (p = .003). CONCLUSION: Actual compared with estimated dental treatment under deep sedation involved more teeth and was of greater complexity. This suggests that referrals should include children with limited estimated treatment plans.

Effect of motivational interviewing on preventive strategies for children receiving full-mouth dental rehabilitation under general anesthesia: A randomized controlled trial.

BACKGROUND: Motivational interviewing (MI) is an approach to increase parental compliance to follow up and recall of their children. It has proven to be successful in motivating parents to adopt and maintain preventive child oral health behaviors. AIM: To assess the effectiveness of motivational interviewing on prevention strategies for parents of children who have received full-mouth dental rehabilitation under general anesthesia (GA). DESIGN: This is a parallel-arm randomized controlled trial. Parents in the treatment arm were randomized and received a combination of motivational interviewing, individualized goal setting, visual aids, and verbal education post-GA. Those in the control arm received the same information by verbal and written education. Both groups were evaluated at 2-week follow-up and 3-month recall. Differences in attendance, oral health knowledge, readiness to change, and parental self-efficacy (PSE) were compared between groups and at return visits. RESULTS: Of 74 parents of children randomly allocated in this study, 22 (61%) and 13 (38%) from the intervention group, and 21 (55%) and 16 (46%) from the control group attended the 2-week, and 3-month follow-up, respectively. The average PSE for participants in the intervention group was significantly higher than that of the control group at the follow-up visit (p = .0050). CONCLUSION: Readiness to change dietary habits and average PSE for parents in the intervention group were significantly higher than that of the control group after receiving the modified preventive strategy.

IMPLANT SURVIVAL IN RENAL-TRANSPLANTED PATIENTS: A PROSPECTIVE LONG-TERM STUDY.

The present study aims to assess the feasibility of implant rehabilitation in kidney-transplanted patients. Patients with kidney transplantation included in periodontal supportive care and at least one year of dialysis with mono- or partial edentulism were eligible for this study. Histomorphometric evaluation of the harvested bone was matched with radiological bone assessment. Implant stability was also monitored with RFA and ITV. Fixed cemented prostheses have been delivered after conventional loading protocol. Supportive periodontal therapy has been administered. Eleven patients (9 males and 2 females) were included. The mean age was 58.1 ± 9.9 years. A total of 17 implants were inserted and analyzed. Mean ITV was 39.3 ± 23.8 Ncm. The mean primary stability (ISQ) at T0 was 71.7 ± 10.5, whereas the mean secondary stability at T1 was 73.0 ± 7.3. The minimum follow-up was 62 months, with a maximum of 84 months (7 years) reached by four patients. Fourteen out of 15 implants were in function at a 5-year follow-up (survival rate 93.3%). Two implants showed peri-implantitis. Seventeen bone samples were collected (13 in the mandible and 4 in the maxilla). The mean percentage of marrow spaces and lamellar bone was 41.6% and 58.4%, respectively. Class 3, according to Misch classification, was found as the mean value of radiological bone density. It can be concluded that implant-supported rehabilitation in kidney-transplanted patients is possible. Adequate periodontal maintenance allows implant rehabilitation in kidney transplanted patients with long-term sufficient survival rates.

Factors associated with dental clinic use by clients in Nigeria during the COVID-19 pandemic.

BACKGROUND: Nigeria, like many other countries, faced challenges in dental care provision during the COVID-19 pandemic, necessitating limited care to emergencies only. However, the impact of restricted access to dental services on oral health remains a concern, particularly with preventive maintenance care. This study aims to identify the factors associated with dental service utilization during the COVID-19 pandemic among patients attending dental clinics in Nigeria, and their sources of information about COVID-19. METHODS: This cross-sectional study recruited 500 participants who had visited dental clinics before and during the pandemic. Data were collected through telephone interviews and online questionnaires between September and December 2021. Inferential analyses were conducted using ordered logistic regression models to assess the association between the independent (awareness of emergency dental treatments, knowledge of COVID-19 transmission routes in dentistry, awareness of required preparations in dental practice settings, fear of COVID-19 infection in dental settings), and dependent (utilization of dental services during the pandemic) variables after adjusting for confounding variables (age, sex, educational status, COVID-19 vaccinations status and COVID-19 status of live-in residents). The sources of COVID-19 information by dental patients was also identified. Statistical significance was established at 95% confidence level with a p value < 0.05. RESULTS: Many participants were males (51.2%) and had tertiary education (61.6%). Fear of COVID-19 infection in dental settings was significantly associated with lower odds of utilizing dental care services during the pandemic (Adjusted Odds Ratio: -0.06, 95% Confidence Interval: -0.08, -0.01). The main sources of COVID-19 information were mass media and social networks, with only 42% receiving information from dental professionals. CONCLUSION: Fear of COVID-19 infection in dental settings significantly influenced dental service utilization during the pandemic. Strategies to address fear and improve communication channels between dental professionals and patients are essential for promoting oral health during similar crises.

Postoperative evaluation of special needs and healthy patients with endodontic treatment under general anesthesia: a retrospective research.

BACKGROUND: This retrospective clinical study was undertaken to comparatively evaluate the number of restorative treatments, endodontic treatments, and tooth extractions performed for patients under general anesthesia due to dental anxiety or special needs between 2015 and 2022 and to examine the pain, bleeding, nausea, and vomiting data of those patients. METHODS: In total, 1165 patients underwent dental treatment under general anesthesia in the faculty hospital. Those under the age of 15 and with no endodontic procedure planned (n = 918) were excluded, followed by those with incomplete data (n = 25) and those without endodontic treatment (n = 25). Patients who underwent at least one endodontic treatment were finally included in the study (n = 184). Patients were divided into two groups: healthy and with special needs. Dental treatments were recorded as endodontic, restorative, and teeth extractions. Endodontic treatments were classified according to the tooth type (premolar, molar, and incisors). The composite restorations were classified as anterior, occlusal (O), occluso-distal (OD) or occluso-mesial (OM), and mesio-occluso-distal (MOD) restorations and patients' post-treatment pain, nausea, vomiting, and bleeding were recorded. The data were analyzed statistically. RESULTS: Among the 184 patients included in the study, 70 (38%) were healthy, and 114 (62%) had special needs. Postoperative bleeding was observed more in patients with special needs (χ2 = 4.189, p < 0.05), whereas pain was observed more in healthy patients (U = 2922.00, p < 0.05). While the number of anterior, O, and MOD restorations was higher in patients with special needs, the number of OD or OM restorations was higher in healthy patients (χ2 = 74.877, p < 0.05). CONCLUSIONS: Patients with special needs undergo a greater number of restorative treatments compared to control patients, which may be associated with the inadequate oral hygiene care of such patients. However, restorative treatment is mostly indicated for such patients in our faculty hospital, which may indicate that a conservative approach is taken. Additionally, the finding that postoperative bleeding was more severe in this group of patients compared to the control group in this study may emphasize the need to consider more possible complications after general anesthesia in these patients.

Early childhood caries, climate change and the sustainable development goal 13: a scoping review.

BACKGROUND: Sustainable development goal 13 centres on calls for urgent action to combat climate change and its impacts. The aim of this scoping review was to map the published literature for existing evidence on the association between the Sustainable Development Goal (SDG) 13 and early childhood caries (ECC). METHODS: The scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. In August 2023, a search was conducted in PubMed, Web of Science, and Scopus using search terms related to SDG13 and ECC. Only English language publications were extracted. There was no restriction on the type of publications included in the study. A summary of studies that met the inclusion criteria was conducted highlighting the countries where the studies were conducted, the study designs employed, the journals (dental/non-dental) in which the studies were published, and the findings. In addition, the SDG13 indicators to which the study findings were linked was reported. RESULTS: The initial search yielded 113 potential publications. After removing 57 duplicated papers, 56 publications underwent title and abstract screening, and two studies went through full paper review. Four additional papers were identified from websites and searching the references of the included studies. Two of the six retrieved articles were from India, and one was China, Japan, the United States, and the United Kingdom respectively. One paper was based on an intervention simulation study, two reported findings from archeologic populations and three papers that were commentaries/opinions. In addition, four studies were linked to SDG 13.1 and they suggested an increased risk for caries with climate change. Two studies were linked to SDG 13.2 and they suggested that the practice of pediatric dentistry contributes negatively to environmental degradation. One study provided evidence on caries prevention management strategies in children that can reduce environmental degradation. CONCLUSION: The evidence on the links between SDG13 and ECC suggests that climate change may increase the risk for caries, and the management of ECC may increase environmental degradation. However, there are caries prevention strategies that can reduce the negative impact of ECC management on the environment. Context specific and inter-disciplinary research is needed to generate evidence for mitigating the negative bidirectional relationships between SDG13 and ECC.

A comparative study of microbial changes in dental plaque before and after single- and multiappointment treatments in patients with severe early childhood caries.

BACKGROUND: The status of dental caries is closely related to changes in the oral microbiome. In this study, we compared the diversity and structure of the dental plaque microbiome in children with severe early childhood caries (S-ECC) before and after general anaesthesia and outpatient treatment. METHODS: Forty children aged 3 to 5 years with S-ECC who had completed whole-mouth dental treatment under general anaesthesia (C1) or in outpatient settings (C2) were selected, 20 in each group. The basic information and oral health status of the children were recorded, and the microbial community structure and diversity of dental plaque before treatment (C1, C2), the day after treatment(C2_0D), 7 days after treatment (C1_7D, C2_7D), 1 month after treatment (C1_1M, C2_1M), and 3 months after treatment (C1_3M, C2_3M) were analysed via 16 S rRNA high-throughput sequencing technology. RESULTS: (1) The alpha diversity test showed that the flora richness in the multiappointment group was significantly greater at posttreatment than at pretreatment (P < 0.05), and the remaining alpha diversity index did not significantly differ between the 2 groups (P > 0.05). The beta diversity analysis revealed that the flora structures of the C1_7D group and the C2_3M group were significantly different from those of the other time points within the respective groups (P < 0.05). (2) The core flora existed in both the pre- and posttreatment groups, and the proportion of their flora abundance could be altered depending on the caries status of the children in both groups. Leptotrichia abundance was significantly (P < 0.05) lower at 7 days posttreatment in both the single- and multiappointment groups. Corynebacterium and Corynebacterium_matruchotii were significantly more abundant in the C1_1M and C1_3M groups than in the C1 and C1_7D groups (P < 0.05). Streptococcus, Haemophilus and Haemophilus_parainfluenzae were significantly more abundant in the C1_7D group than in the other groups (P < 0.05). CONCLUSION: A single session of treatment under general anaesthesia can cause dramatic changes in the microbial community structure and composition within 7 days after treatment, whereas treatment over multiple appointments may cause slow changes in oral flora diversity.

Dental Treatment in Special Needs Patients and Uncooperative Young Children: A Retrospective Study.

Background and Objectives: Special Needs Patients (SNPs) and young non-collaborative children are more predisposed to develop oral pathologies due to poor collaboration and scarce access to dental treatment. The aim of this retrospective study was to analyze a sample of SNPs who received dental treatments either under general anesthesia (GA) or deep sedation (DS) over a period of 6 years. The number and type of procedure were analyzed. Materials and Methods: In total, 131 patients were included and mostly (>90%) treated under GA. Patients were either uncooperative and phobic (Group 1) or affected by mental, behavioral, and neurological disorders (Group 2), diseases of the nervous system (Group 3), or developmental anomalies (Group 4). Results: Patients in Group 2 required more invasive dental treatments than those in the other groups. Therapies were mainly preventive and restorative, except in Groups 3 and 4, where extractions were more frequent. The type of dental treatment significantly varied according to age and systemic condition. Only 5.3% of the patients needed a second intervention, despite only 17.6% of patients respecting the scheduled follow-up. Conclusions: Treatment under GA is effective, but the poor adherence to follow-ups and the risk of reintervention should be contrasted by improving the perception by parents/guardians of the importance of oral hygiene and periodic visits.

DO ORAL CARE AND REHABILITATION IMPROVE COGNITIVE FUNCTION? A SYSTEMATIC REVIEW OF CLINICAL STUDIES.

OBJECTIVES: An increasing number of studies have identified an association between oral health status and cognitive function. However, the effect of oral interventions, including oral health care, dental treatment and oral motor exercises, on cognitive function remains unclear. This systematic review examined whether oral interventions contribute to the long-term improvement of cognitive status. METHODS: Four databases were searched (MEDLINE, Web of Science, Cochrane Library, and ICHUSHI Web) to identify randomized and nonrandomized controlled trial studies and prospective cohort studies from inception until 1 September 2023, published in English or Japanese. The Cochrane risk of bias tool for randomized controlled trials and the risk of bias assessment tool for nonrandomized studies were used to assess bias risk. RESULTS: A total of 20 articles were included in the qualitative analysis; 13 articles were published in English, and 7 were published in Japanese. The implemented interventions were oral care in 8 studies, dental treatment in 8 studies, and oral motor exercise in 4 studies. One study found a significant effect on attention following oral care intervention. Some dental treatments influenced cognitive function, although a clear positive effect was not determined. In 1 study, attention and working memory improved in the chewing exercise group. CONCLUSIONS: Several studies verified the improvement effects of oral interventions, such as oral care, dental treatment, and oral motor exercise, on cognitive function or impairment. However, there was still a lack of conclusive evidence that such an intervention clearly improved cognitive function. To clarify the effects of oral interventions on cognitive function, it is necessary to examine participants, interventions, and outcome measures in detail.

Impact of oral health literacy and psychoactive substances on tooth loss in adolescents.

The aim of the present study was to investigate associations between tooth loss, and oral health literacy, the use of multiple psychoactive substances, and the reason for the last dental appointment in adolescents. A cross-sectional study was conducted with a representative sample of 746 adolescents aged 15-19 years in Campina Grande, Brazil. Parents/guardians answered a sociodemographic questionnaire. The adolescents answered the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30), the alcohol, smoking, and substance involvement screening test, and an oral health questionnaire from the National Oral Health Survey. The adolescents were then examined by two examiners who had undergone training and calibration exercises for the diagnosis of tooth loss due to caries (K > 0.80). Associations between variables were investigated using robust logistic regression analysis for complex samples (α = 5%). The prevalence of tooth loss was 17.4%. Oral health literacy (OR = 0.93; 95% CI: 0.89-0.97) was inversely associated with tooth loss, while multiple psychoactive substance use (OR = 2.01; 95% CI: 1.09-3.69) and last dental visit for treatment/symptoms (OR = 3.05; 95% CI: 1.73-5.36) were directly associated with tooth loss. Oral health literacy, multiple psychoactive substance use, and reason for last dental appointment exerted an influence on tooth loss among adolescents.

Catastrophic out-of-pocket payments for dental treatment: regional evidence from Spain.

BACKGROUND: To estimate the incidence and concentration of catastrophic out-of-pocket payments for healthcare and dental treatment, by region in Spain (calculated as the proportion of households needing to exceed a given threshold of their income to make these payments) in 2008, 2011 and 2015. METHODS: The data analysed were obtained from the Spanish Family Budget Survey reports for the years in question. The study method was that proposed by Wagstaff and van Doorslaer (2003), contrasting payments for dental treatment versus household income and considering thresholds of 10%, 20%, 30% and 40%, thus obtaining incidence rates. In addition, relevant sociodemographic variables were obtained for each household included in the study. RESULTS: With some regional heterogeneity, on average 4.75% of Spanish households spend more than 10% of their income on dental treatment, and 1.23% spend more than 40%. Thus, 38.67% of catastrophic out-of-pocket payments for dental services in Spain corresponds to payments at the 10% threshold. This value rises to 55.98% for a threshold of 40%. CONCLUSIONS: An important proportion of catastrophic out-of-pocket payments for health care in Spain corresponds to dental treatment, a service that has very limited availability under the Spanish NHS. This finding highlights the need to formulate policies aimed at enhancing dental cover, in order to reduce inequalities in health care and, consequently, enhance the population's quality of life and health status.

The risk of endocarditis in hemodialysis patients who have undergone invasive dental treatment: a cohort case-control analysis of the Taiwan National Health Insurance Database.

OBJECTIVE: The objective of this study was to determine if hemodialysis patients who have undergone an invasive dental treatment are at risk of developing infective endocarditis. MATERIALS AND METHODS: This study was a cohort case-control design and used secondary data collected from the National Health Insurance Research Database of Taiwan. The case group and the control group were each comprised of 19,602 hemodialysis patients. The control group was matched for four variables: age, gender, a medical history of diabetes mellitus, and a cerebrovascular event. After matching, the case group and the control group were each comprised of 19,602 hemodialysis patients. Cox regression analysis determined hazard ratios and 95% confidence intervals. RESULTS: Patients were followed up at 1 month and 3 months after receiving invasive dental treatment. The results showed the cohort case-control hazard ratio was 0.88 (95% CI, 0.49, 1.57) 1 month after receiving invasive dental treatment. Three months after receiving IDT, the cohort case-control hazard ratio was 1.04 (95% CI, 0.71, 1.52). Hazard ratios did not differ significantly between groups. CONCLUSIONS: Hemodialysis patients who received invasive dental treatment had no greater risk of developing infective endocarditis than matched control patients. The results of this study should alleviate concerns for hemodialysis patients and dentists about invasive dental treatment procedures. We recommend hemodialysis patients undergo invasive dental treatment when needed. CLINICAL RELEVANCE: The results of this study showed that invasive dental treatment did not increase their risk of developing infective endocarditis. Hemodialysis patients in need of an invasive dental procedure should be encouraged to undergo treatment if the dentist deems it necessary.

The impact of general medical health status, demographical, and patient-specific variables on need for dental treatment of children and adolescents under general anesthesia.

OBJECTIVES: Aim of this retrospective study was to examine the influence of general medical, demographical, and other patient-specific factors on the need for dental treatment under general anesthesia in children and adolescents at Saarland University Hospital. For assessment of the clinical treatment need, a mixed dt/DT (decayed teeth) was introduced. MATERIALS AND METHODS: A total of 340 patients under 18 years of age who received restorative-surgical dental treatment between 2011 and 2022 were anonymously enrolled. Demographic and other patient-specific data, general medical health, oral health, and treatment related data were recorded. In addition to descriptive analysis, Spearman-Rho-test, Mann-Whitney-U-test, Kruskall-Wallis-test and Chi-square-test were used. RESULTS: More than half of the patients (52,6%) were in general health, but non-cooperative. The majority of the patients (66.8%) was between 1 and 5 years of age (p < 0,001). Mean dmft was 10.95 ± 4.118, mean DMFT was 10.09 ± 7.885, and mean dt/DT was 10.79 ± 4.273. Analysis showed that communication difficulties significantly influenced dmft (p = 0.004), DMFT (p = 0.019), and dt/DT (p < 0.001). Type of insurance significantly affected dmft (p = 0.004) and dt/DT (p = 0.001). There was no significant effect of ASA on caries experience, however on prevalence of severe gingivitis (p < 0.001), number of extractions (p = 0.002), and need for repeated treatment (p < 0.001). CONCLUSIONS: Need for dental treatment in the present collective was high, independent of the considered variables. Non-Cooperativeness along with ECC was the main indication for dental general anesthesia. The mixed dt/DT was the most precise survey to evaluate clinical treatment needs. CLINICAL RELEVANCE: Given the enormous demand for these rehabilitations with strict selection, it is imperative to create more treatment capacities for patients mandatorily requiring general anesthesia by avoiding it in healthy patients.

Dental anxiety and oral health-related quality of life before and after non-surgical periodontal treatment.

OBJECTIVES: To (1) investigate dental anxiety (DA) and oral health-related quality of life (OHRQOL) before and after non-surgical periodontal treatment (NSPT) and (2) determine correlations between these patient-reported measures. MATERIALS AND METHODS: Demographics, smoking habits, dental pain, Modified Corah's Dental Anxiety Scale (MDAS), and Oral Health Impact Profile (OHIP-14) were assessed in eighty-two participants. RESULTS: Mean age was 48.3 years ± 11.5. At baseline, 8.5% reported being active smokers. Of non-smokers, 11% reported being an ex-smoker. After NSPT, 11.0% reported smoking. Patients' maximal pain in the last month decreased after therapy. Before treatment, participants reported higher DA. Extreme DA was observed in 8.5% of participants before therapy. Afterwards, 2.4% of participants reported extreme DA. Fear of having a foreign object in the mouth decreased after NSPT. All OHIP-14 scores, except functional limitation, improved post-treatment. Higher DA was associated with worse OHRQoL before treatment. After treatment, total MDAS score was associated with OHIP-14 global score, physical pain, psychological disability, and social disability. Worse MDAS sub-scores were associated with a higher OHIP-14 global score. Individuals with "normal/slight anxiety" had a significant improvement in OHRQoL, whereas people in the "moderate and extreme anxiety" group did not report a significant improvement. Patients diagnosed with generalized periodontitis (GP) stage III grade B and GP stage IV grade B reported less anxiety after NSPT. CONCLUSIONS: Associations of MDAS subcategories with OHIP-14 domain scores were found before and after therapy. DA decreases and OHRQoL enhances after NSPT in patients with "normal/slight" anxiety to dental treatment. Dental practitioners should plan strategies to cope with anxiety to dental treatment and prevent decreases in OHRQoL. CLINICAL RELEVANCE: Within the limitations of this study, DA and OHRQoL were positively correlated in patients with periodontitis, before and after NSPT, using the MDAS and OHIP-14 questionnaires. The results of our study suggest that treatment is effective in terms of alleviating DA and improving oral health, along with quality of life, in patients that report "normal/slight" anxiety to dental treatment. Nonetheless, results must be interpreted with caution since patients are generally anxious before any type of dental treatment. DA may not just be confined to NSPT per se. According to our results, evaluation of both outcomes should be an integral part of routine periodontal clinical evaluation and periodontal reevaluation of initial therapy. It is important that clinicians learn to identify patients that suffer from anxiety and take time to explain the treatment procedures to the patient, to strive for patient's emotional well-being before, during, and after dental care services. The use of specific questionnaires for both DA and OHRQoL may be more appropriate to demonstrate the psychological and quality of life differences due to periodontal disease and NSPT.

Comparing Direct Measurements and Three-Dimensional (3D) Scans for Evaluating Facial Soft Tissue.

The inspection of patients' soft tissues and the effects of various dental procedures on their facial physiognomy are quite challenging. To minimise discomfort and simplify the process of manual measuring, we performed facial scanning and computer measurement of experimentally determined demarcation lines. Images were acquired using a low-cost 3D scanner. Two consecutive scans were obtained from 39 participants, to test the scanner repeatability. An additional ten persons were scanned before and after forward movement of the mandible (predicted treatment outcome). Sensor technology that combines red, green, and blue (RGB) data with depth information (RGBD) integration was used for merging frames into a 3D object. For proper comparison, the resulting images were registered together, which was performed with ICP (Iterative Closest Point)-based techniques. Measurements on 3D images were performed using the exact distance algorithm. One operator measured the same demarcation lines directly on participants; repeatability was tested (intra-class correlations). The results showed that the 3D face scans were reproducible with high accuracy (mean difference between repeated scans <1%); the actual measurements were repeatable to some extent (excellent only for the tragus-pogonion demarcation line); computational measurements were accurate, repeatable, and comparable to the actual measurements. Three dimensional (3D) facial scans can be used as a faster, more comfortable for patients, and more accurate technique to detect and quantify changes in facial soft tissue resulting from various dental procedures.

Efficacy and safety of remimazolam besilate for sedation in outpatients undergoing impacted third molar extraction: a prospective exploratory study.

BACKGROUND: Dental treatments often cause anxiety, fear, and stress in patients. Intravenous sedation is widely used to alleviate these concerns, and various agents are employed for sedation. However, it is important to find safer and more effective sedation agents, considering the adverse effects associated with current agents. This study aimed to investigate the efficacy and safety of remimazolam besilate (hereinafter called "remimazolam") and to determine the optimal dosages for sedation in outpatients undergoing dental procedures. METHODS: Thirty-one outpatients aged 18-65 years scheduled for impacted third molar extraction were included in the study. Remimazolam was administered as a single dose of 0.05 mg/kg followed by a continuous infusion at a rate of 0.35 mg/kg/h, with the infusion rate adjusted to maintain a sedation level at a Modified Observer's Assessment of Alertness/Sedation (MOAA/S) score of 2-4. The primary endpoint was the sedation success rate with remimazolam monotherapy, and the secondary endpoints included induction time, recovery time, time until discharge, remimazolam dose, respiratory and circulatory dynamics, and frequency of adverse events. RESULTS: The sedation success rate with remimazolam monotherapy was 100%. The remimazolam induction dose was 0.08 (0.07-0.09) mg/kg, and the anesthesia induction time was 3.2 (2.6-3.9) min. The mean infusion rate of remimazolam during the procedure was 0.40 (0.38-0.42) mg/kg/h. The time from the end of remimazolam administration to awakening was 8.0 (6.7-9.3) min, and the time from the end of remimazolam administration to discharge was 14.0 (12.5-15.5) min. There were no significant respiratory or circulatory effects requiring intervention during sedation. CONCLUSIONS: Continuous intravenous administration of remimazolam can achieve optimal sedation levels without significantly affecting respiratory or circulatory dynamics. The study also provided guidance on the appropriate dosage of remimazolam for achieving moderate sedation during dental procedures. Additionally, the study findings suggest that electroencephalogram monitoring can be a reliable indicator of the level of sedation during dental procedural sedation with remimazolam. TRIAL REGISTRATION: The study was registered in the Japan Registry of Clinical Trials (No. jRCTs061220052) on 30/08/2022.
