Restauração indireta em resina composta: um relato de prontuário / Indirect resin composite restoration: a dental record report

Restaurações diretas em resina composta são amplamente utilizadas em odontologia para restaurar dentes posteriores. Todavia, quando há grande destruição coronária, onde a distância do istmo excede dois terços da distância intercuspídea, as restaurações indiretas em resina composta são indicadas. O presente estudo teve como objetivo relatar a análise de um prontuário de um paciente que recebeu uma restauração indireta em resina composta em dente posterior amplamente destruído. Através da análise de prontuários de pacientes atendidos nas disciplinas de Estágios Supervisionados do Curso de Odontologia da FSG Centro Universitário no ano de 2023, foi selecionado um prontuário de um paciente que compareceu a clínica odontológica da FSG com uma restauração em amálgama fraturada com reparo em resina composta que apresentou sintomatologia dolorosa. O procedimento diagnóstico ocorreu através de exame clínico e radiográfico, que constatou a indicação de substituição da restauração insatisfatória e realização de uma restauração indireta em resina composta. Os resultados estéticos e funcionais apresentados demostraram a viabilidade da técnica restauradora indireta em resina composta para reabilitar dentes posteriores com ampla destruição coronária(AU)

Direct composite resin restoration are widely used in dentistry to restore posterior teeth. However, when there is large coronary destruction, that the distance from the isthmus exceeds two- thirds of the intercuspal distance, indirect composite resin restorations are indicated. This study aimed to report the analysis of a dental record of a patient who received an indirect restoration in composite resin in a badly destroyed posterior tooth. Through the analysis of dental records of patients seen in the disciplines of Supervised Internship of the Dentistry Course at FSG Centro Universitário in the year 2023, the dental record of a patient who attended the FSG dental clinic with fractured amalgam restoration with composite resin repair was selected who had painful symptoms. The diagnostic procedure took place through clinical and radiographic examination, which revealed the indication of replacing the unsatisfactory restoration and carrying out an indirect restoration in composite resin.The aesthetic and functional results presented demonstrated the viability of the indirect composite resin restoration technique for rehabilitating posterior teeth with extensive coronal destruction(AU)

Alunos canhotos de odontologia da cidade de Uberlândia: perfil, ergonomia e dores osteomusculares / Left-handed dentistry students in the city of Uberlândia: profile, ergonomics and muscular pain

Os dentistas são um grupo de alto risco para o desenvolvimento de doenças de desordens musculoesqueléticas e tendo em vista que o sistema de produção industrial desenvolve produtos que atendem a maioria da população destra, os estudantes canhotos precisam se adequar a uma formação acadêmica, usando instrumentais, cadeiras odontológicas eoutros objetos projetados para destros. O presente trabalho teve como objetivo a coletade informações sobre os canhotos nos cursos de Odontologia da cidade de Uberlândia ­Minas Gerais. Foram incluídos todos os alunos canhotos matriculados no ano de 2022 e que estavam cursando ou já cursaram disciplinas com atividades laboratoriais ou clínicas. Questionários foram aplicados para identificação do perfil, das dificuldades, da ergonomia e das dores osteomusculares dos alunos canhotos em suas atividades. Os dados foram em seguida tabulados e passaram por análise estatística. Da quantidade total de alunos das três instituições (n=1.578), foram entrevistados 45 (2,8%) alunos canhotos, sendo a maioria feminina (80%), na qual identificou-se um posicionamento inadequado do operador canhoto quando comparado ao preconizado pela ISO-FDI, além da limitação de movimento na presença de auxiliar (82,2%). Os locais com maior frequência de dor/desconforto foram: pescoço (79%), costas superior esquerda (63%) e inferior esquerda (61%) e punhos/ mãos esquerda (56%). A intensidade da dor variou entre alguma, moderada e bastante. O impedimento de realizar atividades diárias foi relatado por 17% dos alunos (n=7) e destes somente 1 buscou atendimento médico. Não houve diferença estatística na comparação entre instituição pública e privada. Diante dos resultados, concluiu-se que os canhotos representam minoria dos alunos de Odontologia e apresentam várias regiões de dor/ desconforto devido às adaptações e posturas erradas durante os atendimentos. Apesar de grande parte apresentar dor, poucos tiveram impedimento de atividades rotineiras ou procuraram ajuda médica(AU)

Dentists are a high risk group for the development of musculoskeletal disorders and considering that the industrial production system develops products that serve the majority of the right-handed population, lefthanded students need to adapt to an academic training, using instruments, dental chairs and other objects designed for right-handers. This study aimed to collect information about left-handers in Dentistry courses in the city of Uberlândia - Minas Gerais. All left- handed students enrolled in the year 2022 and who were taking or had taken courses with laboratory or clinical activities were included. Questionnaires were applied to identify the profile, difficulties, ergonomics and musculoskeletal pain of left-handed students in their activities. The data were tabulated and then undergo statistical analysis. Of the total number of students from the three institutions (n=1,578), 45 (2.8%) left-handed students were interviewed, the majority being female (80%), in which an inadequate positioning of the left-handed operator was identified when compared to the recommended one by ISO-FDI, in addition to limitation of movement in the presence of an assistant (82.2%). The places with the highest frequency of pain/discomfort were: neck (79%), upper left back (63%) and lower left back (61%) and left wrists/hands (56%). The intensity of pain varied between some, moderate and a lot. The impediment to carrying out daily activities was reported by 17% of the students (n=7) and of these, only 1 sought medical attention. There was no statistical difference when comparing public and private institutions. In view of the results, it was concluded that left-handers represent a minority of dentistry students and have several regions of pain/discomfort due to adaptations and wrong postures during consultations. Although most of them had pain, few were prevented from performing routine activities or sought medical help(AU)

Importância da assistência odontológica dentro do ambiente hospitalar / Importance of dental care within the hospital enviroment

A assistência odontológica é imprescindível para a prevenção de doenças infecciosas e para a manutenção da integridade da cavidade oral de pacientes internatos em unidades de terapia intensiva. O objetivo deste estudo foi avaliar o conhecimento e as práticas de higiene oral dos acadêmicos do curso de Enfermagem de uma instituição de ensino superior, que realizam estágio em hospital, no controle de higiene bucal de pacientes internados em ambiente hospitalar. Participaram do estudo 40 alunos, que responderam 14 perguntas com o intuito de avaliar o conhecimento e as práticas no controle de higiene bucal, realizadas por eles, em pacientes internados em ambiente hospitalar. Os resultados demonstraram que os acadêmicos entrevistados tinham idade média de 25,8 anos, sendo 95% do sexo feminino e apenas 5% do sexo masculino. Destes, 42,5% afirmaram não haver presença de um Cirurgião-Dentista em ambiente hospitalar e 82,5% responderam que o responsável pela saúde bucal dos pacientes é do técnico de enfermagem. Quanto aos cuidados em pacientes internados em UTI, 52,5% dos entrevistados relataram que estes pacientes recebem higienização bucal, porém 30% alegaram que esta pratica não era realizada e 17,5% não sabiam responder. Além disso, 47,5% dos entrevistados afirmam ter insegurança ao realizar os procedimentos de higiene bucal dos pacientes. Pode-se concluir que os acadêmicos entrevistados possuem bom conhecimento acerca da importância dos cuidados com a saúde bucal dos pacientes internados em ambiente hospitalar. No entanto, ainda existem muitas dúvidas relacionadas ao manejo clínico de procedimentos de promoção de saúde bucal, que poderiam ser solucionados com a presença de um profissional de Odontologia inserido em uma equipe multidisciplinar(AU)

Oral care is essential for the prevention of infectious diseases and for maintaining the integrity of the oral cavity of patients hospitalized in intensive care units. The objective of this study is to evaluate the knowledge and oral hygiene practices of Nursing students at a higher education institution, who carry out internships in a hospital, in controlling the oral hygiene of patients admitted to a hospital environment. 40 students participated in the study, who answered 14 questions with the aim of evaluating the knowledge and practices in controlling oral hygiene, carried out by them, on patients hospitalized in a hospital environment. The results demonstrated that the academics interviewed had an average age of 25.8 years, with 95% being female and only 5% being male. Of these, 42.5% stated that there was no presence of a Dental Surgeon in a hospital environment and 82.5% responded that the nursing technician is responsible for the patients' oral health. Regarding care for patients admitted to the ICU, 52.5% of those interviewed reported that these patients receive oral hygiene, however 30% claimed that this practice was not performed and 17.5% did not know how to answer. Furthermore, 47.5% of those interviewed say they are insecure when carrying out oral hygiene procedures for patients. It can be concluded that the academics interviewed have good knowledge about the importance of oral health care for patients hospitalized in a hospital environment. However, there are still many doubts related to the clinical management of oral health promotion procedures, which could be resolved with the presence of a dentistry professional within a multidisciplinary team(AU)

Harold C. Slavkin: A Transformative Leader of Our Times.

Harold (Hal) C. Slavkin, DDS, the 22nd president of the American Association for Dental, Oral, and Craniofacial Research (1993 to 1994), died on December 22, 2023. During a career that spanned almost 6 decades, Hal distinguished himself as an international authority on craniofacial biology and an advocate for oral health equity. He served as dean of the University of Southern California's dental school, founded the school's Center for Craniofacial Molecular Biology, created the nation's first PhD program in craniofacial biology, and served as the sixth director of the National Institute of Dental and Craniofacial Research. Hal's studies of the molecular and cellular underpinnings of craniofacial malformations prepared him to champion translational research later in his career, when his work with patient advocates revealed the importance of applying new discoveries to clinical practice. A visionary thinker, skilled administrator, progressive educator, compelling communicator, researcher, scholar, and mentor, Hal was known as a Renaissance leader. He rejoiced in fostering collaborative synergies among people and organizations. Throughout his life, family was his central grounding force. He and his wife, Lois, advanced a wide range of social and community initiatives and took great pride in their children, grandchildren, and great-grandchildren. We remember Hal for his indelible spirit, unflappable enthusiasm for science, fierce advocacy for social justice, and infectious zest for life. Here, we outline his multidimensional accomplishments through the lenses of academia, government, and nonprofit organizations. Although it is with heavy hearts that we bid goodbye to this remarkable man, our spirits are lightened by the many gifts he left behind.

Persistent gender disparity in leading dental publications across four decades: An observational study.

OBJECTIVE: This observational study assessed the differences in the gender of the first and last authors in the most cited dental articles over the last four decades. STUDY DESIGN AND SETTING: Articles were obtained through an electronic search of the most cited articles in dentistry by decade (total n = 400 articles). The 100 most cited studies in each decade (1980 - 1989, 1990 - 1999, 2000 - 2009, and 2010 - 2019), with any study design, with results in dentistry were eligible. The gender of the first and last authors was determined using the Genderize database. Comparative evaluation of gender distribution in general and across the four decades was performed with the Chi-Square test, and the contribution of variables on the citation rate of articles was performed using Linear Regression. RESULTS: There were statistical differences between the gender distributions, with a predominance of men in the first (83.8%) and the last (86.8%) positions (p<0.001). Over the decades, there was a tendency for an increase in the proportion of women as the last author (p = 0.002; Chi-Square Trend Test). However, no statistically significant differences were observed between the genders for the first author in the last four decades (p = 0.163; Chi-Square Trend Test), with an increase of women from 6% to 22% across the last four decades. CONCLUSION: The findings indicate that men lead a large percentage of the most cited articles in dentistry and that this trend does not show substantial modifications over the last years. Nonetheless, for the position of last authorship, an increase in women's representativity was observed over the last decades.

Obesity and dental caries in childhood: trends in prevalence and socioeconomic inequalities-a multicohort population-wide data linkage study.

OBJECTIVES: To quantify levels of coexisting obesity and caries experience in children in Scotland, and any associated socioeconomic inequalities over the years 2011/2012-2017/2018. DESIGN: A multicohort population-wide data linkage study. SETTING: Local authority primary schools in Scotland. PATIENTS: 335 361 primary 1 (approximately 5 years old) schoolchildren in Scotland between 2011/2012 and 2017/2018. MAIN OUTCOME MEASURES: Prevalence and inequalities in coexisting caries and obesity. RESULTS: The prevalence of coexisting obesity and caries experience was 3.4% (n=11 494 of 335 361) and did not change over the 7 years. Children living in the 20% most deprived areas had more than sixfold greater odds of coexisting obesity and caries experience than children from the 20% least deprived areas (adjusted OR=6.63 (95% CI=6.16 to 7.14; p<0.001)). There was a large persistent socioeconomic gradient across the Scottish Index of Multiple Deprivation groups, with the Slope and Relative Indices of Inequality remaining unchanged over the 7 cohort years. CONCLUSIONS: Despite improvements in oral health in children in Scotland, the prevalence of coexisting obesity and caries experience has remained static, with large persistent inequalities. These conditions are likely to signal increased risk of chronic conditions including multimorbidity in adulthood and therefore early identification of children most at risk and timely intervention tackling common risk factors should be developed and evaluated.

Comparison of the accuracy of bracket axial positioning with and without radiographic support and according to practitioner experience: A three-dimensional study.

INTRODUCTION: Accurate bracket positioning remains challenging. To avoid angulation errors, some recommend examining the panoramic radiograph during bonding. However, it can cause distortions. Cone-beam computed tomography (CBCT) provides a more precise panoramic reconstruction but with higher radiation doses. The main objective of this study is to compare the accuracy of axial positioning between direct bonding without radiography, with conventional panoramic radiograph, and with panoramic reconstruction from CBCT. The secondary objectives are to evaluate positioning accuracy of each tooth and to assess the influence of practitioner level of experience. METHODS: Thirty practitioners, divided into two groups based on their experience performed direct bonding on a model thrice: without radiography, then with the conventional panoramic radiograph, then with the panoramic reconstruction from CBCT. Models were scanned, and angulation errors were measured using OrthoAnalyzer. Values were compared using the Friedman's test followed by the Bonferroni correction for multiple comparisons (P-value = 0.05). RESULTS: For the low level of experience group, angulation errors were significantly greater than the accepted limit without radiographic reference, and significantly lower with CBCT reconstruction. For the high level of experience group, angulation errors were significantly lower than the accepted limit for the three bonding methods. For every tooth, using the panoramic reconstruction from CBCT as a reference, was the most accurate method, regardless of the level of experience. More experienced practitioners made fewer errors for the three methods. CONCLUSIONS: Panoramic reconstruction from CBCT is the most accurate method to limit angulation errors during direct bonding. Conventional panoramic radiography remains a reliable tool if used with caution. Bonding without any radiographic reference should be avoided especially for less experienced practitioners.

Oral health status of institutionalized older adults receiving domiciliary dental care: A cross-sectional retrospective study.

AIM: This study aimed to evaluate the oral health of care-dependent institutionalized older adults receiving domiciliary dental care. METHODS AND RESULTS: Dental health records of institutionalized adults receiving regular domiciliary dental care were examined (observation period: 5 years). Relevant demographic and oral health information were extracted. Statistical analyses included descriptive and non-parametric tests (α = .05). Records of 398 nursing home residents (mean-age: 84.9 ± 6.4 years) were included. Average time spent by the residents in the institution was 2.8 ± 1.5 years. The mean number of teeth present and the overall DMF-T score was 14.7 ± 9.1 and 27.4 ± 6.2, respectively. The DMF-T score increased until the 3-year recall, with a significant increase in the number of decayed teeth (2-year: p = .013; 3-year: p = .010). An improvement in the residents' periodontal health was seen during the observation period but was not statistically significant. CONCLUSION: The findings of this cross-sectional study confirmed that regular domiciliary dental care provision to institutionalized older adults helps maintain gingival and periodontal health. However, the incidence of dental caries might still be a problem that needs to be addressed with effective measures that improve the daily oral care provision to these older adults.

The Influence of Thickness on Light Transmission for Pre- and Fully Crystallized Chairside CAD/CAM Lithium Disilicate Ceramics.

AIM: This in vitro study aimed to compare the light-transmission properties of two chairside CAD/CAM lithium disilicate (LD) ceramics (a novel fully crystallized and a traditional pre-crystallized) across varying thicknesses. MATERIALS AND METHODS: One hundred flat specimens were obtained from precrystallized (e.max CAD, Ivoclar Vivadent, Schaan, Liechtenstein) and fully crystallized (LiSi GC Block; GC, Tokyo, Japan) LD at five different thicknesses (0.5, 0.75, 1.0, 1.50 and 2.0 mm). All specimens were polished with a polishing system for lithium disilicate restorations following recommendations from the manufacturer. Light transmission was evaluated with a radiometer. The statistical analysis between e.max CAD and LiSi GC Block was performed using a Mann-Whitney test for each thickness at a significance level of 0.05 (p < 0.05), followed by a Kruskal-Wallis test to compare the light transmission between the thicknesses of e.max CAD and LiSi GC Block. RESULTS: Light transmittance was significantly affected by ceramic thickness. The 0.5 mm thick specimens exhibited the highest transmittance values compared to all other groups, while a light transmittance of 0.00 was observed in the 2.0 mm thick specimens for both e.max CAD and LiSi GC Block. In the comparison between e.max CAD and LiSi GC Block according to thickness, there was a statistically significant difference exclusively between groups with a thickness of 1.50 mm (p = 0.002). CONCLUSIONS: Light transmission for pre- and fully crystallized CAD/CAM lithium disilicate ceramics only showed a statistical difference at the thickness of 1.50 mm (p = 0.002). E.max CAD demonstrated acceptable light transmission up to a thickness of 1.5 mm. CLINICAL SIGNIFICANCE: A thickness of 2 mm for chairside CAD/CAM lithium disilicate ceramics, whether pre-crystallized or fully crystallized, necessitates the use of dual-cure resin luting cement due to reduced light transmission.

Correlations between Dental Age, Skeletal Age, and Mandibular Morphologic Index Changes in Turkish Children in Eastern Anatolia and Their Chronological Age during the Pubertal Growth Spurt Period: A Cross-Sectional Study.

In age determination, different methods aiming to obtain the closest result to chronological age have been investigated so far. The most commonly used one among these is the radiological method, which is usually used to evaluate the developmental stages of wrist bones or teeth. In our study, we assessed bone age estimations using the Gilsanz-Ratib atlas (GRA), which has recently become commonly used for children aged 9 to 15 years; evaluated the dental age, determined with Cameriere's European method; conducted morphometric measurements of the mandibular bone; and then examined their relationships with chronological age. The results of our study reveal that, in children during the puberty growth spurt, Cameriere's EU formula might have higher accuracy in estimating chronological age in younger age groups, while the GRA might be more accurate for older ages. Additionally, we conclude that of the mandibular morphometric measurements, condylar height and tangential ramus height show strong positive correlations with age. As a result, we conclude that the morphometric measurements evaluated in the present study can be used as auxiliary methods in forensic anthropology and forensic dentistry.

A Comparative Analysis of Mechanical Properties of Polyetheretherketone (PEEK) vs. Standard Materials Used in Orthodontic Fixed Appliances: A Systematic Review.

Polyetheretherketone (PEEK), an organic thermoplastic polymer, has gained interest in dentistry due to its excellent mechanical strength, flexibility, and biocompatibility. Furthermore, the ability to utilize CAD/CAM in the fabrication of PEEK enhances accuracy, reliability, and efficiency while also saving time. Hence, several orthodontic studies have explored the utilization of PEEK in various applications, such as archwires, brackets, fixed lingual retainers, palatal expansion devices, transpalatal arches, Tübingen palatal plates, different types of space maintainers, mini-implant insertion guides, and more. However, a complete systematic review of the available data comparing the performance of PEEK with traditional orthodontic materials has not yet been conducted. Therefore, this systematic review seeks to assess if PEEK material meets the required mechanical criteria to serve as an alternative to conventional orthodontic appliances. To ensure clarity and precision, this review will specifically concentrate on fixed appliances. This systemic review followed the PRISMA guidelines and utilized databases including PubMed/MEDLINE, Embase, Springer, Web of Science, and Wiley. Searches were restricted to English language articles from January 2013 to February 2024. Keywords such as "Polyetheretherketone" or "PEEK" and "Orthodontic" or "Orthodontic device" or "Orthodontic materials" were employed across all databases. Nine studies were incorporated, covering orthodontic archwires, brackets, and fixed lingual retainers. Based on the reviewed literature, PEEK demonstrates promising potential in orthodontic fixed appliances, offering advantages in force delivery, friction reduction, and aesthetic appeal. Further research is needed to fully explore its capabilities and optimize its application in clinical practice.

Predicting the employment of teledentistry in clinical practice by the Saudi dental community using a theoretical model.

Introduction: There are very few scholastic studies applying a theory-driven methodology to analyse the employment of teledentistry in clinical practice by the Saudi dental community. The objective of this research was to predict the employment of teledentistry in clinical practice by the Saudi dental community using the UTAUT (Unified Theory of Acceptance and Use of Technology) model. Methods: A countrywide survey was executed from November 2022 to April 2023 among the dental community (pre-graduate students, graduates, post-graduate students, general dentists, and specialist dentists) involved in clinical practice. The survey employed the UTAUT model, which has four fundamental constructs: performance expectancy (PE), effort expectancy (EE), social influence (SI) and facilitating conditions (FC). These constructs are known to impact the user's behavioural intention (BI). The four fundamental constructs were independent, and BI was the dependent variable. A Likert scale with five scores was used to record each variable. Descriptive statistics were used to describe all the constructs. Cronbach's alpha scores were used to measure the inner consistency of the Likert scale. Simple linear regression and multiple linear regression were used to determine the correlation between all the constructs and the overall model's prediction. The Statistical Package for the Social Sciences was applied for analysis. The study had 80% power and an alpha threshold of .05. Results: The electronic survey was sent to 3000 participants, out of whom 2143 responded (response rate = 71.43%). PE (R2= 26%, p < .01) was the most significant predictor of the Saudi dental community BI to employ teledentistry in clinical practice, followed by SI (R2= 24%, p < .01), EE (R2= 19%, p < .01) and FC (R2= 6%, p < .01). With statistically significant predictive power, the UTAUT model explained 32% of the variance in the BI (R2= 0.32, p < .01). Conclusions: Each UTAUT construct and the entire model were significantly correlated with the employment of teledentistry in clinical practice by the Saudi dental community. PE had the most salient correlation, followed by SI, EE and FC. The participants have perceived the benefits of teledentistry, increasing the future likelihood of its utilisation. The Saudi government could consider the UTAUT constructs to promote teledentistry in tandem with Vision 2030.

Effectiveness of Preoperative Alpha Wave Entrainment in Pediatric Dental Patients: A Randomized Controlled Trial.

Background Pediatric dental anxiety is a significant barrier to effective dental care, necessitating non-pharmacological interventions. Alpha wave entrainment has shown promise in adult studies for reducing procedural anxiety and pain perception, but its effectiveness in pediatric dental settings remains underexplored. Objective This study aims to evaluate the effectiveness of preoperative alpha wave entrainment in alleviating anxiety in gender-specific participants to the interventions. Methods We conducted a randomized controlled trial involving 252 pediatric patients (aged 7-12) with cooperative dispositions. Participants were randomly assigned to either an experimental group receiving alpha wave entrainment or a control group receiving conventional behavior management techniques. The experimental intervention involved 10-minute sessions of binaural beats with visual stimulation designed to induce alpha-wave synchronization. Anxiety levels were assessed using physiological measures (heart rate and blood pressure), both pre- and post-interventions. Results The intervention group demonstrated a significant reduction in heart rate and systolic blood pressure post-intervention compared to the control group. These changes indicate a decrease in anxiety levels, with no significant gender differences in the response to the intervention. Conclusion Alpha wave entrainment effectively reduces dental anxiety in pediatric patients, with similar efficacy observed across genders. This study supports the incorporation of alpha wave entrainment into pediatric dental practices as a viable alternative to traditional anxiety management techniques.

Orthodontic Elastics: A Multivariable Analysis of YouTubeTM Videos.

Background/Purpose: Whether YouTube videos contain precise and adequate information on certain orthodontic procedures remains unclear. This study aimed to investigate the content and quality of YouTube videos on orthodontic elastics and identify the predictors of high-level content YouTube videos. Materials and Methods: Two hundred YouTube videos were screened for eligibility, and after applying the inclusion criteria, 133 videos were excluded. Student's t-test was used to compare the characteristics, quality parameters, and total content of the low-level and high-level content videos. Chi-square or Fisher's exact tests were implemented to identify the source and content element differences across low-level and high-level content videos. Pearson's correlation coefficients were used to determine the relationship between the total content score, video information and quality index (VIQI), and YouTube characteristics. Stepwise linear multiple regressions with forward selection were used to test the association of the YouTube characteristics and VIQI with the total content score. Results: Among 67 included videos, only 19.4% of videos were classified as high-level content videos. High-level content videos had significantly higher mean number of likes (MD = 4041.7; SD = 4680.7; P-value=0.0068), VIQI score (MD = 4.17; SD = 4.87; P-value=0.0073), and total content score (MD = 4.04; SD = 1.23; P-value=<0.0001). The adjusted linear regression model demonstrated a significant association between the total content score and VIQI, where 1 unit increase in the VIQI was significantly associated with a 0.16 increase in the total content score (B = 0.16; standard error [SE]=0.04; P = 0.0003). Further, a significant association was observed between the total content score and video duration, where 1 minute increase in the video duration was significantly associated with a 0.15 increase in the total content score (B = 0.15; SE = 0.05; P = 0.008). Conclusion: This study demonstrated that YouTube content quality concerning orthodontic elastics is poor. Thus, future implementation of online visual content provided by certified orthodontists will ensure accurate and thorough information delivery.

Case-finding for HPV vaccination eligibility within a dental office with concurrent development of a dialogue tool.

Background: Human papillomavirus (HPV) immunization can prevent cancers, but uptake has been incomplete (and worse with the COVID-19 pandemic). Dental clinicians already screen for oral cancers, many of which are caused by HPV, and could identify vaccination candidates, but this requires a case-finding strategy. Objective: The purpose of this study was (1) to develop and test a case-finding approach to identify patients who were candidates for HPV vaccinations, (2) to test an HPV vaccination intervention by dental professionals on vaccination uptake. Methods: Design: Prospective, non-randomized feasibility case finding study with a 4-week enrollment period and a 6 week follow up period in general dental offices.Setting: Two general and non-commercial dentistry offices in Edmonton, Alberta Canada.Subjects: Consecutive scheduled (non-emergent) patients who met the Health Canada criteria for HPV vaccination: immunocompetent males and females aged 9-45 years and those who are immunocompromised. Consent for the discussion was obtained from each subject or parent.Intervention: Scheduled dental patients meeting the inclusion criteria were flagged by a research assistant who reviewed the appointment schedule each week for 4 weeks. For these subjects, dental clinicians (dentists and dental hygienists) used our Dental Dialogue Tool to discuss HPV vaccination and answer questions. Participating patients who consented to receive the HPV vaccine were given a prescription by the attending dentist and were directed to follow-up with a local pharmacy to have the vaccine administered. Each participant that was provided with an HPV prescription was contacted after 6 weeks to identify if they received the first dose of vaccine.Outcomes: Yield of our case-finding strategy and receipt of a patient's first HPV vaccine dose during 6 weeks post vaccine prescription. Results: Our case-finding strategy assessed 656 scheduled patients over 4 weeks. From this screening,179 (a case-finding yield of 20.4 %), were candidates for HPV vaccine discussion. Forty-three of these 179 patients (24 %) were already vaccinated.. Two patients (1.1 %) did not consent to be spoken with and 134 (74.8 %) consented to the HPV vaccine discussion.. Forty-eight of 134 patients (35.8 %) of patients accepted a prescription from the dentist after speaking with the dental clinician. Ultimately, 8/48 (16 %) (patients received their first dose of the HPV vaccine by the 6 week of follow-up call. However, this is only 4.5 % (8/177) of those patients who did consent for the discussion of HPV cancers and vaccination from their dentist. Conclusion: We demonstrated that case-finding for HPV vaccine candidates in general dental offices was feasible, with a reasonable yield. While the dental dialogue tool was described as a great resource to explain the facts and answer questions, very few patients were vaccinated after 6 weeks of follow-up. Further work is necessary to sharpen the intervention, perhaps including follow-up discussions with the dental clinicians.

Exploring dental professionals' outlook on the future of dental care amidst the integration of artificial intelligence in dentistry: a pilot study in Pakistan.

OBJECTIVE: The purpose of this study is to explore the perspectives, familiarity, and readiness of dental faculty members regarding the integration and application of artificial intelligence (AI) in dentistry, with a focus on the possible effects on dental education and clinical practice. METHODOLOGY: In a mix-method cross-sectional quantitative and quantitative study conducted between June 1st and August 30th, 2023, the perspectives of faculty members from a public sector dental college in Pakistan regarding the function of AI were explored. This study used qualitative as well as quantitative techniques to analyse faculty's viewpoints on the subject. The sample size was comprised of twenty-three faculty members. The quantitative data was analysed using descriptive statistics, while the qualitative data was analysed using theme analysis. RESULTS: Position-specific differences in faculty familiarity underscore the value of individualized instruction. Surprisingly few had ever come across AI concepts in their professional lives. Nevertheless, many acknowledged that AI had the potential to improve patient outcomes. The majority thought AI would improve dentistry education. Participants suggested a few dental specialties where AI could be useful. CONCLUSION: The study emphasizes the significance of addressing in dental professionals' knowledge gaps about AI. The promise of AI in dentistry calls for specialized training and teamwork between academic institutions and AI developers. Graduates of dentistry programs who use AI are better prepared to navigate shifting environments. The study highlights the positive effects of AI and the value of faculty involvement in maximizing its potential for better dental education and practice.

Evaluation of different taste sensations along with body mass index (BMI) in geriatric patients with and without complete dentures.

BACKGROUND: The purpose of this study was to investigate the effect of acrylic full removable dentures on the perception of four primary tastes (sweet, sour, salty, and bitter), as well as to determine if there is a correlation between changes in body mass index (BMI) and taste perception. MATERIALS AND METHODS: A total of 60 patients who wore acrylic removable dentures and 60 controls were included in the study as a convenient sample. Sixteen solutions for basic tastes were prepared, and the patients were asked to identify the taste of each solution from the lowest concentration. Anthropometric measures, such as height and weight, were measured and recorded in an MS-Excel sheet. The data were analyzed using SPSS version 23. RESULTS: The results showed that patients with complete removable dentures had lower taste scores for sourness (P < 0.001) and sweetness (P < 0.001) compared to the control group. However, there was no significant difference in salt taste scores (P = 0.218) and bitterness (P = 0.002) between the two groups. Additionally, the study found a correlation between lower BMI values and higher taste scores among denture-wearing patients, indicating an inverse relationship between total taste scores and BMI. CONCLUSIONS: The study suggests that geriatric patients with complete dentures have reduced taste sensations compared to those without dentures which can have a negative impact on their nutritional status. Therefore, it is crucial to provide adequate nutritional support and dietary counseling for geriatric patients based on health policy to maintain their overall health and well-being.

Robot-assisted surgery for dental implant placement: a narrative review.

OBJECTIVE: To determine the current status and accuracy of robotic computer-assisted implant surgery (CAIS) applications by examining the associated clinical and experimental outcomes. DATA AND SOURCES: PubMed, Medline, and Cochrane Library databases were searched for relevant studies published between January 2000 and November 2023, and focusing on robotic CAIS in dental implant surgery. All search results were then manually reviewed to identify only the pertinent articles. Only in vitro and clinical studies were included in this narrative review, with implant placement accuracy considered the main outcome. RESULT: Based on our inclusion and exclusion criteria, we included 21 studies (with 1085 implant sites); of them, 8 were clinical studies, 12 were in vitro studies, and 1 included both an in vitro study and a case series. The ranges of the mean implant shoulder, apical, and angular deviations were respectively 0.43-1.04 mm, 0.53-1.06 mm, and 0.77°-3.77° in the clinical studies and 0.23-1.04 mm, 0.24-2.13 mm, and 0.43°-3.78° in the in vitro studies, respectively. CONCLUSION: The accuracy of robotic CAIS in dental implant procedures appears to be within the clinically acceptable ranges. However, further relevant clinical trials validating the existing evidence are needed. CLINICAL SIGNIFICANCE: Robotic CAIS can achieve clinically acceptable implant placement accuracy. This innovative technology may improve the precision and success rates of dental implant procedures, with benefit for surgeons and patients.

Temperament and past behaviour can predict behaviour success for nitrous oxide sedation.

BACKGROUND: There is currently insufficient evidence on potential predictors of a child's behaviour with nitrous oxide (N2O) sedation. AIM: To examine the association between a child's temperament and behavioural outcomes during dental treatment with N2O sedation, and the child's perception to N2O sedation. DESIGN: At the first visit (dental treatment visit), temperament was assessed using the Child Behaviour Questionnaire-Short Form and behaviour was assessed by an independent rater using the Venham Behaviour Rating Scale. At the second visit, the child's experience with N2O sedation was elicited. RESULTS: Seventy-two healthy children aged between 36 and 95 months were recruited. Planned dental treatment was completed in 84.7% of the subjects. Venham behaviour success <3 and Venham behaviour success <1 were achieved in 73.6% and 33.3%, respectively. The temperament domain of effortful control was associated with Venham behaviour score (ρ = -0.266, p = .024) and Venham behaviour success <1 (OR = 3.506, 95% CI = 1.328-9.259, p = .011). Baseline Frankl behaviour score was significantly associated with all behavioural outcomes. Venham behaviour success <3 was significantly associated with a child reporting to have enjoyed the dental treatment visit (p = .026). CONCLUSION: Effortful control and baseline behaviour were associated with behavioural outcomes of N2O sedation and can be used to predict a child's behaviour.
