Evaluation of oroantral communication potential risk during maxillary teeth extraction in patients with different types of facial skeleton

Abstract

Relevance. Tooth extraction is the most common operation in oral surgery practice. For oroantral communication (OAC) treatment and prevention as one of the surgery complications, it is paramount to study the prevalence of anatomical risk factors for OAC in patients based on their facial sk eleton type.Materials and Methods. We analyzed 1629 cone-beam CT scans of patients aged 18 to 85 years of both sexes to determine the potential risk of OAC in patients with different types of the facial skeleton.Results. The overall assessment of OAC potential risk demonstrated a high risk in 29.7% of cases (4514 teeth) (p < 0.01). The high-risk group determined teeth most often in patients with a mesoprosopic type of facial skeleton – 31.2% of cases (2912 teeth), in euryprosopic – 29.46% (914 teeth), in leptoprosopic – 24.96% of cases, (688 teeth), (p < 0.01). The potential risk of the first and second molar OAC was the highest of all teeth in all facial skeleton types (p < 0.01).Conclusion. A potentially high OAC risk of about 30% can be related to the upper teeth, located in the maxillary sinus floor area in patients with any facial skeleton type, though the risk is higher in meso- and euryprosopic types (p < 0.01). Among all groups of teeth, the highest potential risk of OAC (up to 40%, p < 0.01) is in the maxillary 1st and 2nd molar region in any facial sk eleton type.
