Assessment of the distribution of facial root fenestration in maxillary anterior teeth in Saudi sub-population using cone-beam computed tomography: Retrospective study

[摘要] Introduction: The aim of this study is to assess the destitution of facial root fenestration in maxillary anterior teeth among the Saudi population in cone-beam computed tomography (CBCT) scans. Materials and Methods: A total of 100 CBCT scans of maxillary anterior teeth were evaluated for the presence, location, and type of the fenestration. The age, gender, number of fenestrations, and their location was displayed by frequency and percentage. Data were statistically analyzed. Results: The overall prevalence of root fenestration in the facial bone of maxillary anterior teeth was 80%. It was higher in females (57.5%) than males. The most common tooth being affected by fenestration was lateral right incisor (35.0%). The most common type of root fenestration was Type IV (52.5%). No significant difference was found between all types of fenestrations and all age groups (P < 0.365). The highest mean of fenestration height was found in relation to the left canine (7.1 mm) and lowest was in lateral right incisor (4.9 mm). Conclusions: Females and lateral right incisor areas were the most commonly affected by the root fenestration of Type IV.
