Abstract: (184 Views)
Introduction: The first permanent molar, with its large occlusal surface and early eruption, plays a pivotal role in oral health. This study assessed the association between caries in the first permanent molar and caries in the second molar, second premolar, and overall dentition.
Materials and Methods: In this cross-sectional study, 632 volunteers aged 18–20 years from Qazvin (2023) were examined using clinical and radiographic assessments based on a standardized checklist. Pearson’s correlation test was applied, with significance set at P = 0.05.
Results: A significant association was observed between the condition of the first permanent molar and both the second premolar and second permanent molar. Individuals with caries in the first permanent molar were more likely to have decay in the second permanent molar (r = 0.024) and second premolar (r = 0.021). A positive correlation was also found between the DMF index (Decayed, Missing, and Filled teeth) and the DMF6 index (specific to first permanent molars), showing that higher DMF6 values were associated with higher overall DMF scores (P = 0.001).
Conclusion: The status of the first permanent molar reflects overall oral health and total DMFT score and may serve as a predictive indicator for other teeth. Early monitoring of first molar status can guide preventive interventions, a finding of considerable interest to dental researchers and clinicians.
