Introduction: Inappropriate growth of the third molar can endanger the health of the second molar and cause complications such as root resorption, caries, periodontal disease, etc. The aim of this study was to investigate the effect of third molar, on periodontal status and adjacent second molar caries.
Materials & Methods: The study was descriptive-analytical, 226 teeth were examined from patients referred to Bandar Abbas Dental School in 1402-1403. Patients were evaluated with radiographic and clinical examination to detect caries and probe depth in 4 areas in second molar. Finally, the obtained data were analyzed using independent t-test, ANOVA , chi-square test and significance level of 0.05 was considered.
Results: The average age of the people who had caries of the second molar and probe depth over 3 mm was higher and this difference was statistically significant. The prevalence of caries did not have a significant relationship with the degree of impaction (erupted, partially erupted, impacted). However the probe depth more than 3 mm was greater in fully erupted teeth and this difference was statistically significant. Also, the rate of caries of the second molar associated with the type of vertical impaction was higher than other types of impaction and this difference was significant.
Conclusion: It is important to pay attention to oral and dental hygiene and the examination of the third molar specially at older ages, and early removal of third molars is recommended to prevent the decay of adjacent teeth, periodontal disease and subsequent complications.
