Analysis of post-extraction consequences of posterior maxillary molars on antral sinus in periodontitis patients: A preliminary qualitative two dimensional panoramic study (Prevalence study)

Aim Extraction of the posterior maxillary teeth is the main cause behind maxillary sinus expansion. The aim of the present study was to examine the relationship between extraction of maxillary posterior teeth and sinus expansion in periodontitis patients. Materials and methods A preliminary cross-sectional study was conducted. Two hundred participants underwent clinical and radiographic examination using panoramic radiograph. Results Based on the data analysis of the examined sample, no statistical correlation was reported between the maxillary sinus dimensions and age, gender, periodontal condition, alveolar ridge resorption as well as the number of missing teeth. Conclusions It was concluded that extraction of maxillary posterior teeth, periodontal condition and alveolar ridge resorption could not be considered as risk factors for maxillary sinus pneumutization.
