Background: The aim of this study is to analyze the correlation parameters between the distal caries of the mandibular second molars and the eruption status of the mandibular third molars, the presence of antagonist teeth and general oral hygiene by calculating the DMFT index.
Methods: This is a retrospective cross-sectional study that included a total of 679 orthopantomograms. Age, gender, angle of mandibular second molars according to Winter classification, depth degree according to Pell-Gregory classification, presence of antagonist teeth, DMFT index and distal caries of mandibular second molars were recorded. The obtained data were analyzed using SPSS and descriptive statistics Mann Whitney U and Chi-square test.
Results: Third molars in the vertical position in fully erupted teeth and in mesioangular position in partially erupted teeth increased the risk of distal caries in second molars. However, no statistically significant difference was observed (p≥0.05). Third molars in Class A position increased the risk of distal caries on both sides with statistically significant difference (p≤0.001). The presence of antagonist teeth (p=0.002) and DMFT index (p<0.001) statistically affected the presence of distal caries in the right second molar.
Conclusions: It has been observed that third molars cause caries formation in the adjacent tooth. Although the DMFT index and the presence of antagonist teeth give an approximate idea about fully erupted teeth, it is not a safe enough parameter. Therefore, it would be appropriate to evaluate clinically and radiologically at younger ages and to make an extraction decision if necessary. |
