Development and Validation of the SCAN-Score to Indicate General Anesthesia for Dental Care in Children.

Background: General anesthesia is an approach used to address behavior issues in pediatric dentistry. This indication often relies on the practitioner's discretion rather than objective criteria. We developed SCAN-score to assist pediatric dentists in the case of doubt to indicate general anesthesia for uncooperative children. The study aims were to assess the validity of the SCAN-score, which aims to indicate general anesthesia or chairside management for dental care. Methods: A retrospective study was performed on children aged between 2 and 10 years who received dental care. The SCAN-score combined three item scales (age, need of care, behavior) and three additional factors: communication barriers, permanent teeth caries, and local anesthesia contraindications. Mean scores were estimated. An ROC curve was constructed with sensitivities and specificities obtained. Results: The study included 284 children, with 154 treated through chairside methods and 130 treated under general anesthesia. The mean score was 5.6 ± 2.8 in the chairside management group and 12.9 ± 1.9 in the general anesthesia group. The sensitivity of the score (cutoff at 10) was 0.99, and the specificity was 0.94. The estimate of the ROC is 0.994. Conclusions: The SCAN-score appears to be an excellent tool to support the practitioner's decision to refer to general anesthesia care.

Child oral health: A plea for interdisciplinarity / La santé orale de l'enfant : un plaidoyer pour l'interdisciplinarité

A child's oral health has major implications both for their general health and for their quality of life. Even before birth, the mother's oral health can affect the development of the baby and pregnancy outcomes. From the very first months of life, feeding habits together with non-nutritive sucking ones, early transmission of pathogenic bacteria, and oral hygiene practices prefigure the child's future health. The aim of this article is to provide a comprehensive overview of our current knowledge regarding the main oral health issues affecting children, namely dental caries, erosive tooth wear, developmental defects of enamel, maxillofacial growth anomalies, and traumatic dental injuries. Additionally, it aims to examine the oral health prevention and promotion programs that have been implemented in France over several decades. These prevention and promotion initiatives are not only part of a national program but are also being organized at a territorial level, although, unfortunately, they often remain limited to regional, departmental, or municipal scopes. It is essential for all those involved with children, whether they are health care professionals or not, to collaborate effectively to enhance both oral health and overall well-being. This requires fostering an interdisciplinary approach that involves various contributors working together in a complementary way.

La santé orale de l'enfant est d'un enjeu majeur, tant pour sa santé en général que pour sa qualité de vie. Avant même sa naissance, la santé orale de la mère impacte le développement du bébé et l'issue de la grossesse. Dès les tout premiers mois de vie, le mode d'alimentation, les habitudes de succion non nutritives, la transmission précoce de bactéries pathogènes et les pratiques d'hygiène orale préfigurent la future santé de l'enfant. L'objectif de cet article est de faire une synthèse des connaissances sur les principales affections bucco-dentaires chez l'enfant que sont la maladie carieuse, l'usure érosive, les défauts de minéralisation, les anomalies de croissance maxillo-faciale et les traumatismes dentaires et de s'interroger sur les programmes de prévention et de promotion de la santé en santé orale en France depuis plusieurs décennies. Des initiatives de prévention et de promotion de la santé orale s'organisent (en complément du programme national), dans une déclinaison territoriale, encore trop souvent seulement régionale, départementale ou municipale. Ainsi, ce sont tous les acteurs autour de l'enfant, professionnels de la santé ou non, qui doivent s'engager, ensemble, pour améliorer sa santé orale et sa santé en général et c'est tout une culture interdisciplinaire qui doit se développer autour d'une pluralité d'acteurs qui pourraient agir et collaborer, en toute complémentarité.

Managing the sexualization of the dentist-patient relationship by the patient: Innovative teaching through forum-theatre.

Dental students may be exposed to patients' sexual behavior. We developed a theater-forum session whose aims were to identify when the patient's behavior crosses the line, to collectively develop cover strategies, and to present the reporting system. The strategies pointed out by the group were to ask a pair to be present, set limits on personal life, share discomfort to the patient and report the situation to the staff. Theater-forum is a powerful tool for this learning process.

Risk Factors for High-Arched Palate and Posterior Crossbite at the Age of 5 in Children Born Very Preterm: EPIPAGE-2 Cohort Study.

Introduction: Children born very preterm have an immature sucking reflex at birth and are exposed to neonatal care that can impede proper palate growth. Objectives: We aimed to describe the frequency of high-arched palate and posterior crossbite at the age of 5 in children born very preterm and to identify their respective risk factors. Methods: Our study was based on the data from EPIPAGE-2, a French national prospective cohort study, and included 2,594 children born between 24- and 31-week gestation. Outcomes were high-arched palate and posterior crossbite. Multivariable models estimated by generalized estimation equations with multiple imputation were used to study the association between the potential risk factors studied and each outcome. Results: Overall, 8% of children born very preterm had a high-arched palate and 15% posterior crossbite. The odds of high-arched palate were increased for children with low gestational age (24-29 vs. 30-31 weeks of gestation) [adjusted odds ratio (aOR) 1.76, 95% confidence interval (CI) 1.17, 2.66], thumb-sucking habits at the age of 2 (aOR 1.53, 95% CI 1.03, 2.28), and cerebral palsy (aOR 2.18, 95% CI 1.28, 3.69). The odds of posterior crossbite were increased for children with pacifier-sucking habits at the age of 2 (aOR 1.75, 95% CI 1.30, 2.36). Conclusions: Among very preterm children, low gestational age and cerebral palsy are the specific risk factors for a high-arched palate. High-arched palate and posterior crossbite share non-nutritive sucking habits as a common risk factor. The oro-facial growth of these children should be monitored.

Factors and Mechanisms Involved in Acquired Developmental Defects of Enamel: A Scoping Review.

Background: Developmental Defects of Enamel (DDE) is a pathology of the teeth that can greatly alter the quality of life of patients (hypersensitivity, esthetic issues, loss of function, etc.). The acquired DDE may occur as a result of a wide range of acquired etiological factors and his prevalence of this pathology may reach up to 89.9%. The main objective of this research was to identify and analyze, in current literature, the factors related to acquired DDE, in order to propose a general theory about the mechanisms involved. Methods: The search of the primary literature was conducted until [December 31, 2021]. Our search strategy uses the Pubmed/MEDLINE database and was structured around 3 terms ["Development," "Defect," and "Enamel"]. To be included, references had to be primary studies, written in English. Exclusion criteria were reviews, in vitro, animal, genetic or archeology studies, and studies focused on clinical management of DDE. One hundred and twenty three articles were included in this scoping review: 4 Randomized clinical trials, 1 letter, 5 cases reports, 2 fundamentals studies, and 111 observational studies (33 Cross-sectional studies, 68 Cohort study and 10 Case-control study). The quality of evidence was assessed using the PEDro scale for clinical trials, the Newcastle-Ottawa scale for observational studies, and a published tool to assess the quality of case reports and case series. Results: A scoping review of the literature identified 114 factors potentially involved in acquired DDE. The most frequently encountered pathologies are those causing a disorder of calcium homeostasis or a perturbation of the ARNT pathway in mother or child. The link between the ARNT pathway and metabolism deficiency in uncertain and needs to be defined. Also, the implication of this mechanism in tissue impairment is still unclear and needs to be explored. Conclusions: By identifying and grouping the risk factors cited in the literature, this taxonomy and the hypotheses related to the mechanism allow health practitioners to adopt behaviors that limit the risk of developing aDDE and to set up a prevention of dental pathology. In addition, by reviewing the current literature, this work provides guidance for basic research, clinical studies, and literature searches.

Factors associated with non-nutritive sucking habits at 2 years of age among very preterm children: EPIPAGE-2 cohort study.

BACKGROUND: The association between prolonged non-nutritive sucking habits (NNSHs, ie, sucking pacifiers or fingers) and maxillofacial growth anomalies in the general population has been widely described. Because maturation of sucking abilities is not fully achieved in very preterm infants (<32 weeks' gestation), neonatal services worldwide rely on the use of pacifiers to promote the development of adequate sucking reflexes, possibly prolonging NNSHs during infancy. OBJECTIVE: We aimed to describe the frequency and to identify factors associated with NNSHs at age 2 years in very preterm children. METHODS: The study was based on data from EPIPAGE-2, a French national prospective cohort study of preterm births during 2011 that included 2593 children born between 24 and 31 weeks' gestation. The primary outcome was NNSHs at 2 years. Multivariable log-linear regression models with generalized estimation equations were used to study the association between the characteristics studied and NNSHs. Multiple imputations were used to take into account missing data. RESULTS: The frequency of NNSHs was 69% in the overall sample but higher among girls (adjusted risk ratio [RR] 1.12, 95% confidence interval [CI] 1.05, 1.17), children born from multiple pregnancies (eg, twins/triplets) (RR 1.07, 95% CI 1.00, 1.11), children who were fed by nasogastric tube (RR 1.07, 95% CI 1.01, 1.13), or those who benefitted from developmental care programmes (RR 1.10, 95% CI 1.02, 1.19). The NNSHs frequency was lower if mothers were not born in France (RR 0.70, 95% CI 0.64, 0.77), children had 2 or more older siblings (RR 0.88, 95% CI 0.82, 0.96), or children were breast-fed at discharge (RR 0.90, 95% CI 0.85, 0.95). CONCLUSIONS: NNSHs at 2 years seemed associated with cultural background, development care programmes, and breast feeding. Whether NNSHs at 2 years among very preterm children are associated with future maxillofacial growth anomalies deserves further attention.

OSCEGame: A serious game for OSCE training.

BACKGROUND: Objective Structured Clinical Examinations (OSCEs) are amongst the most anxiety-provoking competency assessment methods. An online serious game (OSCEGame) was developed and implemented within the OSCE curriculum. This study aimed to evaluate the usefulness of this serious game on preparedness and reducing OSCE-related stress. METHODS: A serious game was designed to help dental students train for OSCEs. Two game courses (4 stations each) were designed according to year of undergraduate training (4th and 5th year), based on 6 pre-existing multi-competency OSCE stations. The OSCEGame was available online on a learning platform 4 to 6 weeks before the summative OSCEs. Game use was evaluated by analysing connection data. Preparedness, stress and time management skills were assessed using a questionnaire following the summative OCSEs. The results of 4th -year students (OSCE naive population) were compared to those of 5th -year students to assess usefulness and benefits of such preparation method. RESULTS: In total, 97% and 60% of the students in 4th year and 5th year, respectively, used the game. The game was seen as an essential preparation tool to reduce anxiety (for 60% of all students) and increase time management skills (65% of all students). However, significant differences were observed between 4th- and 5th -year students (anxiety reduction: 65% vs. 22%, p < 0.001; time management skills: 59% vs. 41%, p < 0.05) suggesting that it is most useful for OSCE naive students. CONCLUSION: This serious game is a useful time efficient online tool, for OSCE preparation, especially in OSCE naive students.

Early risk factors for posterior crossbite and anterior open bite in the primary dentition.

OBJECTIVE: To investigate risk factors specific to posterior crossbite and anterior open bite at the age of 3 years. MATERIALS AND METHODS: The study included 422 children of the French EDEN mother-child cohort. The main outcomes were the presence of posterior crossbite and anterior open bite assessed by dentists at 3 years. Social characteristics (collected during pregnancy), neonatal characteristics (collected at birth), duration of breast-feeding (collected prospectively), sucking habits at 3 years, and open lips (as a proxy for mouth breathing) were studied and two logistic regressions conducted. RESULTS: Preterm birth appears to be a risk factor specific for posterior crossbite (OR: 3.13; 95% CI: 1.13-8.68), whereas small for gestational age seems to be associated with a lower risk of posterior crossbite (OR: 0.32; 95% CI: 0.12-0.87). Ongoing pacifier or thumb sucking at 3 years is a risk factor for both posterior crossbite and anterior open bite. CONCLUSIONS: Children born preterm seem to be more at risk for posterior crossbite than those born at term. Different mechanisms may be involved in posterior crossbite and anterior open bite.

Outcome of endodontic treatments made by postgraduate students in the dental clinic of bretonneau hospital.

Objective. The objective of this retrospective study is double: (1) to assess the 1-4 years of outcome of endodontic treatment performed by postgraduate students in endodontics in the Dental Clinic of Bretonneau Hospital and (2) to examine outcome predictors. Method. 363 teeth in 296 patients were treated between 2007 and 2011. 183 patients (224 teeth) were lost during the followup. 113 patients were included in the study (recall: 38%), corresponding to 139 teeth of which 8 were extracted. 131 remaining teeth (36%) were examined clinically and radiographically. Apical periodontitis (AP) was absent (PAI = 1) or present (PAI ≥ 2). Outcome was classified as "healed," "healing," or "diseased". Results. The success rate was 92%. No failure was observed among the 23 initial endodontic treatments. Among the 108 retreated teeth, 80% were "healed" and 11% were "healing." An association was found between success rate and preoperative signs or symptoms (absent 95% versus present 83%), preoperative root filling density (inadequate 93% versus adequate 57%), but not between preoperative AP status and success. Conclusion. Outcomes in this retrospective study were similar to those previously reported. However, a larger sample size is needed to assess outcome predictors more precisely.

Neonatal factors associated with alteration of palatal morphology in very preterm children: the EPIPAGE cohort study.

BACKGROUND: Altered palatal morphology has been observed among some preterm children, with possible consequences on chewing, speaking and esthetics, but determinants remain unknown. AIM: To explore the role of neonatal characteristics and neuromotor dysfunction in alteration of palatal morphology at 5 years of age in very preterm children. STUDY DESIGN: Prospective population-based cohort study. SUBJECTS: 1711 children born between 22 and 32 weeks of gestation in 1997 or born between 22 and 26 weeks of gestation in 1998 were included in the study. They all had a medical examination at 5 years of age. OUTCOME MEASURES: Alteration of palatal morphology. RESULTS: The prevalence of altered palatal morphology was 3.7% in the overall sample, 5.1% among boys and 2.2% among girls (adj OR: 2.52; 95%CI: 1.44-4.42). The risk for altered palatal morphology was higher for lower gestational age (adj OR: 0.85; 95%CI: 0.74-0.97 per week), small-for-gestational age children (adj OR: 2.11; 95%CI: 1.20-3.72) or children intubated for more than 28 days (adj OR: 3.16; 95%CI: 1.11-8.98). Altered palatal morphology was more common in case of cerebral palsy or moderate neuromotor dysfunction assessed at 5 years. Results were basically the same when neuromotor dysfunction was taken into account, except for intubation. CONCLUSION: Male sex, low gestational age, small-for-gestational age and long intubation have been identified as probable neonatal risk factors for alteration of palatal morphology at 5 years of age in very preterm children. Further studies are needed to confirm these results.
