Study of non-metric dental traits of the Gallo-Roman necropolis of La Favorite and the Medieval necropolis of Evans

Objectifs : L’objectif de ce travail consistait à mener une analyse anthropologique des traits non-métriques coronaires de deux collections ostéo-dentaires de localités et époques différentes : La Favorite, gallo-romaine de Lugdunum du I-III siècle et Evans, médiévale du Jura du VII-X siècle.Matériel&méthodes : Les observations ont été réalisées sur 158 sujets. 29 traits coronaires ont été sélectionnés à partir du système ASUDA. Les plaques de référence ont été numérisées. La reproductibilité inter et intra-opérateur a été vérifiée à partir des observations réalisées sur 40 pièces pour chaque collection. La fréquence des grades pour chaque trait a permis de réaliser une comparaison statistique. Le logiciel rASUDAS a permis de rechercher l’origine géographique supposée des sujets atypiques.Résultats : Les valeurs kappa inter-opérateurs variaient de 0,686-1 et kappa intra-opérateur de 0,798-1. La fréquence des grades des traits a été calculée à partir des observations réalisées sur 2643 dents. Le schéma d’usure et d'atteinte carieuse différait entre les collections.Discussion : La fréquence de la plupart des traits dentaires des deux collections est cohérente avec les données des collections européennes disponibles dans la littérature. Le schéma d'usure hélicoïdale est conforme aux données de la période gallo-romaine et médiévale. La prévalence des caries est faible eu égard aux habitudes d’hygiène sommaires des époques concernées, probablement en raison d'une concurrence caries/usure. rASUDAS a permis d'identifier 1 sujet dont l’origine géographique n’est pas identique au reste de la nécropole.Objectives: The objective of this work was to carry out an anthropological analysis of the non-metric coronary features of two osteo-dental collections from different localities and eras: La Favorite, Gallo-Roman from Lugdunum from the I-III century and Evans, medieval from the Jura from the 7th-10th century.Material & methods: Observations were carried out on 158 subjects. 29 coronary traits were selected from the ASUDA system. The reference plates have been digitized. The inter and intra-operator reproducibility was verified from observations made on 40 osteo-dental pieces for each collection. The frequency of grades for each trait allowed a statistical comparison to be made. The rASUDAS software made it possible to search for the supposed geographical origin of the atypical subjects.Results: Interoperator kappa values ​​ranged from 0.686-1 and intraoperator kappa from 0.798-1. The frequency of the grades of the traits was calculated from observations made on 2643 teeth. The wear and caries pattern differed between the collections.Discussion: The frequency of most dental traits in the two collections is consistent with data from European collections available in the literature. The helical wear pattern is consistent with data from the Gallo-Roman and medieval period. The prevalence of caries is low in view of the basic hygiene habits of the times concerned, probably due to competition between caries and wear. rASUDAS identified 1 subject whose geographical origin is not identical to the rest of the necropolis

Hierarchizing caries risk factors among first-year university students in Nice (France): a cross-sectional study

Abstract Background The purpose of this study was to rank the risk factors for dental caries among first-year university students in Nice (France). Methods All first-year students are required to undergo a compulsory preventive medical examination. Among these students, volunteers were offered a dental visit. Information was collected through an interview followed by an oral examination. We assessed the volunteers’ oral hygiene habits (daily toothbrushing frequency, type of toothbrush used, frequency of toothbrush replacement, place of toothpaste purchase, and flossing), daily health-related behaviors (number of main daily meals, daily sugary intakes, smoking, alcohol consumption, consumption of cannabis or other drugs), oral-health-related behaviors (self-reported oral health, dental visits during the past year, reason for the last dental consultation, and failure to seek dental care due to financial reasons), and oral health issues (dental crowding, oral hygiene, presence of caries, presence of pit and fissure sealant remnants). The dependent variable was the presence of at least one untreated carious lesion. The data were subjected to univariate analyses to select explanatory variables, and subsequently, a logistic regression was performed. Results Six hundred twenty-nine students aged 18.8±1.6 years were enrolled in this study. The sex ratio was 0.72, with a strong predominance of the female gender. Only 59.3% of the students had never experienced dental caries, while 22.4% had already undergone restorative procedures and did not have any carious lesion at the time of the examination, and 11.6% presented with carious lesions and had never been treated by a dentist. Lastly, 6.7% had carious lesions despite evidence of prior restorative procedures. The multivariate analysis revealed the following pejorative risk factors: failure to seek dental care due to financial reasons (OR:3.06, 95% CI: 1.40–6.70), poor oral hygiene revealed during the oral examination (OR:2.59, 95% CI: 1.60–4.20), and poor self-reported oral health (OR:2.43, 95% CI: 1.24–4.77). Conversely, the analysis revealed the following protective factors: preventive visits to the dentist (OR:0.63, 95% CI: 0.41–0.99), the use of an electric toothbrush (OR:0.36, 95% CI: 0.17–0.77), and sealant remnants (OR:0.22, 95% CI: 0.05–0.97). Conclusions The highest-ranking caries risk factor for the study population was the financial barrier
