ABSTRACT
Ultra-endurance runners are particularly exposed to caries risk factors due to the continuous intake of sugars in liquid or sticky forms during long-distance exercise. The risk of caries increases due to a failure to perform oral hygiene during races. Ultra-endurance runners had good oral health status despite these particularities. Our hypothesis is that high compliance with preventive oral health recommendations (toothbrushing and preventive or regular dental visits) counterbalance the risks associated with their exposure to caries. We aimed to gain a better understanding of preventive dental behaviors in ultra-endurance runners. We then studied the determinants of two major recommendations: (1) visiting a dentist for preventive check-ups and (2) visiting a dentist during the year. 37% of the total sample reported patterns of both preventive dental visits and recent visits. Early visits (ORa = 4.8***), good oral health (ORa = 8.8**) and tooth brushing (ORa = 2.2**) were associated with preventive dental visits, but there was no significant influence of snacking or weekly work hours. The ultra-endurance race frequency was associated with early dental visits despite equal needs. Most risk-control behaviors were associated with each other, indicating that they are all-or-nothing behaviors. Individual prevention strategies implemented at the dental office may not be as effective as they predominantly target individuals who are already aware of and interested in preventive care. Instead, developing targeted primary prevention strategies that are accessible at race venues, such as stands, villages, or food supply points, could be more effective.

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.
ABSTRACT
This study assessed for the first time the oral and dental health of ultra-trail athletes. We also confirmed and quantified the scale of their exposure to oral health risk factors. This was a cross-sectional study using data from a survey among runners who enlisted in the 2020 edition of the UT4M races (Ultra-Trail des 4 Massifs). The dental health of 84% of the participants was "good" or "very good". The nutritional intake during effort comprised foods liable to induce tooth decay (energy bars (55%), sugar-rich gels and fruit confectionary (40%)) and snacking was frequent (39%). More than 3/5 of runners saw a dentist for preventive check-ups. The more runners participate in races the more likely they are to have oral hygiene strategies during competitions (aOR = 1.85, p ≤ 0.05). The oral health of ultra-trail runners is better than that of the average French adult population. Regular dental hygiene and preventive dental consultations appear to counterbalance the risks that we evidenced.
ABSTRACT
This three-dimensional finite element study compared stresses, intensities and displacements of three mandibular posterior implants restored with cemented crowns (two molars and a premolar in straight line), splinted versus non-splinted. Hundred newton occlusal loads were vertically or horizontally applied, either on one single crown or on all of them. Maximal stresses and implants displacements were higher under horizontal loading. Splinting major effects appeared under single horizontal load with a decrease in stresses (34-49%) and displacements (16-19%) of the loaded crown. Splinting seems more appropriate for implant-supported restorations submitted to frequent single horizontal or oblique loads than vertical ones.
