Correlation of mandibular canal wall resorption with angular cortical thickness among edentulous patients using panoramic radiographs (A comparative study between male and female)

Abstract

Background
Resorption of alveolar bone is the best recognized feature of mandibular aging in
the edentate subject. The aim of this is study to evaluate the mandibular canal wall
resorption using panoramic radiographs among edentulous male and female.
Material and method
The sample of this study was collected from patients who attended Teaching
Hospital of the College of Dentistry at Al- Mustansiria University and panoramic
radiographs were taken in Al-Karama specialized center for dentistry. Forty three
patients were selected in this study with age range between 59-85 years (25 males
and 18 females) . Panoramic radiographs for all patients and sides were examined
and evaluated .
Results
Chi-square between males and females of angular cortical thickness (ACT) ≥
1mm and ACT ˂ 1mm was (37.06) which statistically significant with p-value
(0.008) and between resorption (grades) and age of males was(34.72) which it
statistically significant p-value(0.049) also between resorption (grades) and age of
females was(15.6) which was statistically significant p-value (0.003) . Sperman
correlation showed statistically significant moderate correlation between gender and
age (r=0.581,p-value=0.01) and there was a moderately statistical significant
correlation between the grades of mandibular canal resorption and the angular
cortical thickness measurements in both gender (r=0.532,p-value=0.033).
Conclusion
The resorption of the wall is found more often in edentulous females than in the
males due to hormonal imbalance.
