  ABSTRACT

  Objective: The aim of this study is to investigate whether orthodontic extrusion movements have negative effects on the gingival tissues, and to detect the relationship between orthodontic tooth extrusion and the width of the keratinized gingiva.

  Materials and methods: Fourteen upper canines of seven patients having different Angle classifications were selected for the study. According to the abnormal position of those canines they were subjected to orthodontic extrusion forces in order to bring them back to a normal level within the dental arch and, therefore, to correct the abnormality. Plaque index (PI), probing depth (PD), gingival index (GI), papillary bleeding index (PBI) and keratinized gingiva width (KGW) were measured around the examined canines at baseline, one month, 3 months and 6 months after the initiation of the extrusion movements.

  Results: The values of (PI) and (GI) increased significantly during the whole period of study, whereas the (PD) and (PBI) values did not show any important differences. A very slight increase of the (KGW) of about 0.14 mm was detected at the examined teeth after 6 months comparing to baseline without any statistical significance.

  Conclusions: No negative effects on the gingival tissues were noted around the canines during the application of orthodontic extrusion. All the periodontal parameters were kept within normal limits without any signs of a considerable periodontal destruction.
