Introduction: Bisphosphonates (BP) have recently been used in the treatment of bone diseases. The BP-related osteonecrosis of the jaw (BRONJ) is a severe complication of long-term usage of BP and can lead to serious consequences. This study aimed to evaluate the level of awareness and performance of dentists and senior dental students in Bandar Abbas, Iran, regarding the treatment of patients who take BP. Method: In this cross-sectional study, a questionnaire, based on the standard guidelines, was handed out to dentists and senior dental students in Bandar Abbas city. Variables, such as gender, age, level of awareness, and performance when treating the aforementioned patients were taken into account. The collected data were analyzed using Kolmogorov-Smirnov, Levene, chi-squared, and independent t-test. Result: The performance index was 11.8±2.82 in dentists and 14.29±5.8 in senior dental students which indicates a significant difference between them in terms of performance when treating BRONJ in patients taking BP. However, no significant difference was observed in terms of their knowledge. Conclusion: The level of performance and knowledge in most dentists and dental students was intermediate and policies should be made to raise their abilities. [ABSTRACT FROM AUTHOR]

Purpose: This study investigated the association between the maxillary impacted canines' position and the maxilla's morphological features in an Iranian population based on cone-beam computed tomography (CBCT) images., Material and Methods: In this cross-sectional descriptive-analytical study, 47 CBCT images of unilateral buccally impacted maxillary canines and 47 CBCT images of unilateral palatally impacted maxillary canines were examined. Several morphological variables were compared between the impacted and non-impacted sides, and between the buccal and palatal impaction types., Results: Gender and age were not significantly associated with the canine impaction type. The alveolar bone height at the impacted side was significantly greater in the buccally impacted group than in the palatally impacted group ( p = 0.016). In a comparison of the impacted and non-impacted sides, all variables of alveolar bone thickness at depth of 2 mm, maxillary arch width, and palatal volume had significantly smaller values in the impacted side in both buccally and palatally impacted groups ( p < 0.05). The alveolar bone was significantly thicker at the depth of 10 mm in the impacted side of the buccal group ( p = 0.024). The maxillary arch perimeter was significantly smaller in the impacted side of the buccal group ( p = 0.008). The palatal depth did not significantly differ between the groups., Conclusion: Among the studied variables, the alveolar bone thickness showed contrary results at different depths. The palatal volume and maxillary arch width were significantly smaller on the impacted side in both buccal and palatal groups, and the arch perimeter showed the same results only in the buccal group., (© Pol J Radiol 2024.)
