Abstract

Objective: to determine the prevalence of alveolar bone crest loss among a selected sample of archival orthopantomography (OPG) in relation to number of sites affected and gender in Sulaimani City.

Materials and methods: A retrospective study was conducted with an inclusive period running from March to December 2007 to determine the prevalence of alveolar bone loss among 1072 subjects on panoramic radiographs. Panoramic images were sampled at the radiological archive of Dental School Hospital–University of Sulaimani for a selected age class ranged from 17 to 30 years. Bone loss was estimated by measuring the distance from cementoenamel junction (CEJ) minus 2 mm (physiologic high of interseptal alveolar crest) to the crest of the alveolar bone at sites with reduced normal level of interseptal bone. Total bone loss was divided into two groups according to number of sites affected; group one (1-3) sites showing bone loss per panoramic radiograph, and group 2 showing bone loss at more than 3 sites. Samples were also divided into two age groups; group one from 17 to 23 years and group two from 24 to 30 years. Moreover, bone loss was determined according to gender into male and female and number of sites affected for each gender.

Results: results showed that 347 images – 30.2% of the total images showed bone loss at one site or more. 14.6% of the images revealed bone loss at 1-3 sites, whereas, 15.6% demonstrated bone loss at more than 3 sites. Percentage of bone loss was significantly higher (P=0.001) among group two (24-30 years old group) than group one (17-23 years old group) 38% against 25% respectively. Female’s radiographs recorded a non-significantly higher (P>0.05) bone loss than male’s radiographs 31.7% against 28.7% respectively.

Conclusion: prevalence of bone loss among young adults in Sulaimani City was relatively high compared to other published reports. There was a predilection for female. Bone loss was more prevalent at (24-30 years old group) compared to (17-23 years old group).
