Studies on the location of the mental foramen in Turkish mandibles.

The position of the mental foramen was studied in 58 adult Turkish skulls which were divided into two groups according to age. A previously published method was used to determine the position of the mental foramen. The most common position of the mental foramen lies in line with the longitudinal axis passing between the first and second premolars. This result was in accordance with classical textbooks. Another measurement was also performed on the mental foramen in both groups. The distance between the mental foramen and the mandibular symphysis (A) and the distance between the mental foramen and the inferior border of the mandible (B) were measured. There was a significant difference between the two groups in B, but not in A.

[Long-term evaluation of the periodontal status in extraction treatment]. / Cekimli tedavide periodontal durumun uzun süreli degerlendirilmesi.

In this article the periodontal status of the 30 patients which were treated with Edgewise mechanics, by extraction of four first bicuspids is evaluated approximately 5 years later the active treatment. Comparison of the pocket depths between the teeth moved into extraction areas and the other teeth, is made. And also the pocket depths of the parallel and non-parallel teeth in the extraction area are compared. It is found that orthodontic treatment had no adverse effect on periodontal status in long term. But non-parallel teeth in the extraction area showed much higher values of pocket depth when compared to parallel teeth.
