Incidence and pattern of tooth loss in Thais: Cohort study
Objectives: This cohort study aimed to investigate the incidence and pattern of tooth loss and compare the rates among diverse subgroups of Thai adults.
Methods: A 10-year observational cohort study was conducted among workers of the Electric Generation Authority of Thailand (EGAT) using data from participants who enrolled in the health survey in 2003 and 2013. The primary outcome was the incidence of tooth loss. An event was counted if participants had lost at least one tooth during the observation period. Tooth loss was described by assessing the mean annual tooth loss (teeth/person/year) and the frequency of tooth loss per tooth type. The Kruskal-Wallis and Mann-Whitney U tests were employed to compare the mean annual tooth loss across various subgroups, including sex, age, education, income, smoking, diabetes mellitus, and baseline periodontal status.
Results: Over 10 years, tooth loss affected 51.7% of the 1,855 participants, resulting in the loss of 2,744 teeth (6.0%). The overall tooth loss rate was 0.15±0.24 teeth/patient/year. The most commonly lost teeth were mandibular and maxillary second molars (11.0-13.1%). Mandibular canines were the least frequently lost (1.7-1.9%). Notably, males and individuals with lower education and income levels had a significantly higher rate of tooth loss. Current smokers and those with diabetes mellitus also showed an increased incidence of tooth loss. Furthermore, the severity of periodontitis at baseline correlated with a higher rate of tooth loss.
Conclusions: In conclusion, this study revealed a high prevalence of tooth loss among Thai adults, with over half of the participants experiencing tooth loss over a 10-year period. Molar teeth were more frequently affected. Males, older age, lower socioeconomic status, smoking, diabetes mellitus, and periodontitis severity were identified as significant contributors to tooth loss.
