Correlation of gonial angle size, angular cortical thickness and mandibular bone height with age, gender and dental status in Iraqi sample

الملخص EN

Background: Mandibular angle plays an important role in ensuring a harmonious facial profile from esthetic point of view so it is a representative of mandible morphology.

The aim of the study was to measure the size of gonial angle, angular cortical thickness.and height of mandibular bone using digital panoramic radiography and correlate these 3 measurements with age, gender and dental status Materials and methods: This study was conducted on 90 Iraqi subjects (40 female and 50 male) aged from (20-85) years divided into 3 study groups:Complete dentated .partially dentated and edentulous The collected data were possessed and analyzed using Storage Package of Statistical Science SPSS package program (version 13).

Results: The angle size showed a statistically significant moderately strong positive linear correlation with age in both complete and partial dentition The angular cortical thickness was significantly difference in the mean between complete and partial dentition The thickness showed a statistically significant highly strong negative linear correlation with age The mandibular bone height in edentulous study group showed a statistically significant strong negative [near correlation with age Conclusion: Age associated with increase in gonial angle.

Angular cortical thickness and mandibular bone height decreased with age.
