Abstract

Statement of the Problem: Since children in adulthood are at risk of obesity and caries due to various factors such as diet and poor health habits, these can affect a child's various body systems, including body mass index (BMI) and salivary components, therefore, it is necessary to assess these factors and their relationship in this age group
Purpose: The aim was to evaluate the association between decayed missing filled teeth index (DMFT), salivary alpha amylase (sAA) level and age-specific BMI in adolescent girls.
Materials and Method: A cross-sectional study was conducted on 81 females aged 13-15 years in 3 groups of BMI percentiles; “normal”, “at risk for overweight” and “overweight” (n=27). DMFT was calculated and unstimulated saliva samples were collected. sAA level was measured with a spectrophotometer. Data were analyzed using Kolmogorov-Smirnov test, Kruskal- Wallis and Spearman correlation tests in the software of Statistical Package for the Social Sciences (version 23) at p < 0.05.
Results: The concentration of sAA and Mean DMFT were estimated 1326.56±4.73 U/L and 2.77±2.36, respectively. There was no significant difference in sAA level and Mean DMFT among BMI groups. A positive and significant correlation was found between sAA and DMFT in overweight group (r: 0.46, p = 0.014).
Conclusion: Within the limitation of this study, higher level of sAA may be considered as an indicator for dental caries in overweight adolescent girls.
