RESUMO

Background: Swimming is known worldwide as one of the healthiest, low-impact forms of exercise that promotes a strong body, heart, and mind. However, several studies have suggested that swimming pool chlorination is responsible for dental erosion, calculus formation, and stain in competitive and recreational swimmers, a phenomenon known as swimmer's mouth. The purpose of this observational study was to assess chlorine stain on the dentition of competitive female swimmers and divers from a university team and to determine if dental preventive practices affected chlorine stains. Methods: Swimmers were recruited from the University of New Mexico Swimming and Diving Team for this IRB-approved study (#17-481). Participants completed a questionnaire regarding individual oral habits and frequency of preventive visits. Following the questionnaire, an oral screening was completed to evaluate for stain. Fisher exact tests, nonparametric Wilcoxon tests, and descriptive statistics were used to analyse the data. Additionally, a cross-sectional analysis was used to compare the chlorine stain between divers and swimmers. Results: Twenty-one females, with a mean age of 20.5 years, participated in the study. One hundred percent of these subjects had staining of the teeth, despite the fact that 85% of them reported brushing their teeth 2 to 3 times per day, and 81% reported receiving regular dental prophylaxis. All participants swam 5 or more times every week, with practice length ranging from 1 to 2 hours. There were no differences in stain between collegiate swimmers and divers. Conclusion: Within this study sample, extrinsic staining of the teeth was identified on all swimmers and divers and the presence of stain was not prevented by the frequency of tooth brushing or professional stain removal. Additional oral hygiene regimens should be explored to facilitate the prevention or complete removal of swimmer stain.


Contexte: La natation est reconnue partout dans le monde comme l'une des formes d'exercice physique les plus saines et ayant le moins d'impact, qui renforce le corps, le coeur et l'esprit. Cependant, plusieurs études ont suggéré que la chloration des piscines cause l'érosion dentaire et la formation de tartre et de taches chez les nageurs compétitifs et récréatifs; un phénomène appelé la bouche de nageur. L'objectif de cette étude d'observation était d'évaluer les taches de chlore sur la dentition de nageuses et de plongeuses de compétition d'une équipe universitaire et de déterminer si les habitudes dentaires en matière de prévention influençaient les taches de chlore. Méthodologie: Les nageuses ont été recrutées de l'équipe de natation et de plongeon de l'Université du Nouveau-Mexique pour effectuer cette étude approuvée par le comité d'éthique médicale (#17-481). Les participantes ont répondu à un questionnaire à l'égard des habitudes buccodentaires personnelles et de la fréquence de leurs visites dentaires préventives. À la suite du questionnaire, un dépistage buccal a été effectué pour évaluer les taches. Les tests exacts de probabilité de Fisher, les tests non paramétriques de Wilcoxon et les statistiques descriptives ont été employées pour analyser les données. De plus, une analyse en coupe a servi à comparer les taches de chlore chez les plongeuses et les nageuses. Résultats: Vingt-et-une femmes âgées en moyenne de 20,5 ans ont participé à l'étude. La totalité des sujets avait des taches sur les dents, malgré le fait que 85 % d'entre elles ont signalé avoir brossé leurs dents 2 à 3 fois par jour et 81 % d'entre elles ont rapporté recevoir régulièrement des prophylaxies dentaires. Toutes les participantes ont nagé 5 fois ou plus par semaine et la durée de leur entraînement variait d'une à deux heures. Les nageuses et les plongeuses universitaires n'ont démontré aucune différence dans leur taux de taches. Conclusion: Parmi cet échantillon de l'étude, des taches extrinsèques ont été décelées sur les dents de toutes les nageuses et plongeuses, et la fréquence du brossage de dents ou l'élimination professionnelle des taches n'a pas empêché la présence de taches. Des mesures supplémentaires d'hygiène buccodentaire devraient être explorées afin de faciliter la prévention ou l'élimination complète des taches chez les nageurs.

RESUMO

Purpose: The posterior superior alveolar (PSA) block is one of many techniques used to provide profound anesthesia for invasive dental procedures. This technique has a long history, with a high success rate, but is not without complication risks. The purpose of this study was to determine if pulpal anesthesia of the maxillary second molar could be achieved using a posterior superior alveolar block with a reduced depth of penetration of 10 mm compared to the current suggested depth of 16 mm.Methods: Using a cold refrigerant, a thermal test was conducted using the buccal surface of a maxillary second molar of 43 participants. Positive neural responses were obtained from 100% of the participants (n=43) during the pretest. Each participant received a posterior superior alveolar block using a short (20mm), 27-gauge needle with the penetration depth reduced to 10mm. Post-test neural responses of these molars were evaluated using same cold thermal test technique.Results: Study results demonstrated that the reduced depth technique for the PSA block was successful in 88% (n=38) of the participants; pulpal anesthesia of the maxillary second molar had been achieved. Furthermore, there were zero positive aspirations and zero hematomas observed in the participants.Conclusion: The reduced needle depth technique showed promise in achieving desired results of pulpal anesthesia coupled with decreasing risk and complications associated with the PSA block. Additional blinded, randomized clinical studies are recommended to achieve evidence-based support for this reduced depth PSA block technique.
