Prevalence of Alveolar Bone Dehiscence and Fenestration in Adults with buccally positioned canines-A CBCT Study

Abstract

Detecting alveolar bone fenestrations and dehiscences before orthodontic treatment is imperative due to their potential implications. These defects can contribute to gingival recession and diminish the support structure of canine teeth. Failure to recognize buccal alveolar bone issues increases the risk of treatment relapse.The aim of this study was to determine the prevalence of alveolar bony dehiscence and fenestration in adults with buccally positioned canines. Thirty individuals aged between 18 and 35 undergoing orthodontic treatment in the Department of Orthodontics in the institution were chosen randomly for this study. Their CBCT records were obtained from the Department of Oral Medicine and Radiology, S******* Dental College and Hospital. Statistical analysis was conducted using IBM SPSS Version 23. The chi-square test was employed to explore the relationship between fenestrations, dehiscences, and gender. It was observed that 40% of females had dehiscence, while 36% of males exhibited this condition. Fenestrations were present in 35% of males and 40% of females. In the context of this study's limitations, a statistically significant relationship was found regarding dehiscence width among females (p=0.019, p<0.05), highlighting a heightened vulnerability compared to males. Conversely, the association of fenestration prevalence between males and females did not reach statistical significance (p=0.178, p>0.05). These findings suggest that females may have a greater propensity for bony alveolar dehiscence and fenestration relative to males.
