Risk Factors for Distal Caries of Second Molars Adjacent to Mandibular Impacted Third Molars?

Study Overview
=================
Brief Summary
-----------------
Distal surfaces of second molars adjacent to wisdom teeth are always at risk for caries and external root resorption. The incidence of caries is high, especially in partially impacted third molars in mesioangular and horizontal positions. In this study, investigators aimed to examine the caries correlation in the distal second molar with the age, gender, side and DMFT scores of the participants.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Radiologic examination | Radiologic examination on the distal side of the second molar for tooth decay | 10 minute before the start of surgery | 
| Intra-oral examination | Obtaining DMFT score | 10 minute before the start of surgery | 
| Clinical examination | Clinical examination (intra-oral) on the distal side of the second molar for tooth decay | 1 minutes after the removal of third molar |
