ARTICLE HIGHLIGHTS
Research background

The images of the participants who underwent panoramic graphy were analysed retrospectively. The radiographs taken in the last 1 year retrospectively from the date of the study were used.

Research motivation

The fact that there are few studies on Coronoid Process Hyperplasia was the main motivation of this research.

Research objectives

To detect coronoid process hyperplasia by making repeatable measurements on panoramic radiographs.

Research methods

When Condyle (Cd)-Gonion (Go) and Coronoid (Cor)-Go distances were measured, the Cor-Go:Cd-Go ratio was calculated for the left and right side of each image. Line 1 is the maxillary vertical midline, which passes through the nasal septum. Lines 2, 3 and 4 are perpendicular to line 1 and are tangent to the lower border of the symphysis mandible, the tip of the condyle and the tip of the coronoid process, respectively.

Research results

Coronoid Process Hyperplasia was encountered in only one female out of 300 participants; the prevalence of CPH was found to be 0.3% in the sample subpopulation.

Research conclusions

The Cd-Go and Cor-Go distances were statistically significantly increased in males on both the left and right sides. The evidence that these values were predominant in males may be related to the fact that the anatomical dimensions of males are larger than those of females. Although the Cd-Go and Cor-Go distances were higher in males, the ratio of Cor-Go:Cd-Go was preserved for both genders.

Research perspectives

Present study was not conducted with a large sample group and only one case of CPH was found. in order to reliably obtain the prevalence of CPH, studies with larger sample groups and different ethnic populations are necessary.
