Objetivo: A presente investigação teve como objetivo avaliar a possível relação entre a Síndrome da Apneia Obstrutiva do Sono (SAOS) e o desgaste dentário, em pacientes com estudo de sono previamente realizado.
Materiais e Métodos: Foram observados 65 voluntários, tendo sido excluído apenas 1 (n=64). Foi aplicado o sistema TWES 2.0. para avaliação da prevalência e distribuição do desgaste dentário em pacientes recrutados na consulta de oclusão e assistencial de disfunção temporomandibular da CDEM. A investigadora foi previamente calibrada contra um examinador experiente até um nível de concordância substancial (k=0,784; p<0,001). Analisou-se a correlação entre o desgaste e a SAOS, e outras variáveis dependentes como a idade e o género.
Resultados: A amostra foi composta por 64 participantes, 64,1% do género feminino e 35,9% do género masculino, com uma idade média de 50 anos. A prevalência de SAOS foi 56,3%, dentre os quais 44,4% apresentaram SAOS ligeira, 30,6% moderada e 25% severa. Homens apresentaram maior prevalência de SAOS do que as mulheres (p=0,026).
Em indivíduos com SAOS, o desgaste aumentou significativamente com a idade (p=0,045). Não foi possível estabelecer uma correlação significativa entre o desgaste dentário e a SAOS. As faces oclusais foram as que apresentaram mais desgaste, com grau 2 em ± 50% da amostra, seguidas pelas faces vestibulares, cujo desgaste mais severo também foi de grau 2 ao nível do 4º e 6º sextante, e, por fim, as faces palatinas/linguais do 1º, 2º e 5º sextantes, com um desgaste máximo grau 1.
Conclusões: Devido às limitações na interpretação dos resultados devido ao reduzido tamanho da amostra, somos levados a aceitar a hipótese nula (H0): “pacientes com SAOS apresentam prevalência de desgaste dentário semelhante à de pacientes sem SAOS”.
Objective: This work aimed at evaluating the possible relationship between Obstructive Sleep Apnea (OSA) and tooth wear, in a sample of patients who had previously conducted a sleep study. Materials and Methods: A total of 65 volunteers were observed, with 1 being excluded for not meeting the inclusion criteria (n=64). Tooth wear was measured using the TWES 2.0. index, in patients recruited at the CDEM occlusion and temporomandibular dysfunction appointment. The investigator was previously calibrated against an experienced investigator as a reference, until a substantial agreement level was achieved (k=0,784; p<0,01). The data was analysed for the correlation between tooth wear and OSA, and other variables such as sex and age. Results: The sample consisted of 64 individuals, 64,1% females and 35,9% males, with an average age of 50 years old. The prevalence of OSA was 56,3%, of which 44,4% showed mild, 30,6% moderate and 25% severe OSA. Men showed significantly higher prevalence of OSA (p = 0.026). For individuals with OSA, tooth wear increased significantly with age (p = 0.045). It was not possible to establish a significant correlation between tooth wear and OSA. The most affected tooth locations were the occlusal surfaces, with grade 2 wear in ± 50% of the sample, followed by the vestibular surfaces, with grade 2 as the most severe wear at the 4th and 6th sextants, and finally the palatal/lingual surfaces of the 1st, 2nd, and 5th sextants, with a maximum wear grade of 1. Conclusions: Limitations in the interpretation of the results, due to the reduced sample size, led us to accept the null hypothesis that states H0: “patients with OSA had similar tooth wear prevalence as patients without OSA”.
