A study of the incidence of overeruption, rotation, tipping in unopposed molars and temporomandibular disorders
Öz
Aim: The purpose of this study was to determine the incidence of overeruption, rotation and tipping in unopposed posterior teeth and study the association among temporomandibular disorders (TMD).
Material and Methods: The study group consisted of 191 patients with posterior tooth loss. These teeth (462 molars) overeruption, rotation and tipping records were reviewed. Tooth loss and TMD symptoms were detected. In order to compare the variables Chi-square tests and Fisher’s exact probability test were used. For TMD, Pearson correlation prevalence parameters were used.
Results: 291 molars showed no signs of overeruption. 119 molars showed slight, 52 molars had erupted moderate to severe eruption. 184 molars had no signs of rotation, 203 were rotated less than 15°, while 75 molars were rotated more than 15°. 274 molars showed no signs of tipping whereas, 108 had tipping less than 15°, and 80 molars had tipping of greater than 15°. Younger age group and female gender were found to be statistically significant regarding mean scores of TMDs (Age: p<0.05, Gender: p<0.001)
Conclusions: Molar rotation was more frequent in the maxilla; whereas overeruption and tipping were more common in the mandible Significant associations between the signs of TMD and tooth loss were found, but the current results does not support the concept that loss of molar support is an etiologic factor in TMDs.
