Periodontal Problems of Second Molar Tooth after Surgical Removal of Maxillary Second Molar Tooth

  The mandibular and maxillary third molars are one of the most prevalent impacted teeth. Third molars grow last and it is probable that they face space insufficiency which leads to their impaction. Impacted third molar should be removed from oral cavity surgically due to various side effects which are periodontal problems of second molar and the possibility of root resorption, tumors and cysts, weakness of mandible bone, idiopathic pains. Hence, they should be surgically removed which diminishes further risks. However, the operation may lead to periodontal problems of adjacent second molar tooth and periodontal pocket. The aim of the present study was to evaluate the effect of maxillary third molar removal on the periodontal condition of second molar. 30 patients who were undergoing oral surgery (Third molar extraction) in the Clinic of Dentistry, Mashhad University of Medical Sciences (Iran) in age group of 22 to 26 years enrolled in this study. Pocket depth, attachment loss, plaque index, bleeding on probing were evaluated in middistal, distobuccal, and distolingual sides of second molars pre and 6 months post operation. The pocket depth (P=0.187) and attachment loss (P=0.532) were insignificantly increased in two times (pre operation and 6 months post operation). Plaque (P<0.001), gingival index (P=0.006), and bleeding on probing (P=0.008) were significantly decreased in during time (plaque index=P<0.001). The results indicated that maxillary third molar operation does not negatively affect the periodontal tissues of second molar and this operation does not have any effect on life teeth
