ABSTRACT
Aim: Association between maxillary sinus mucosa/ thickening and periapical pathology - A CBCT study
Objective: To assess the relation between sinus mucosa/ thickening and periapical lesion, to assess anatomic position of root tips with periapical lesion and to correlate age and prevalence of maxillary sinus mucosa/ thickening
Study Design: This retrospective study analysed 100 CBCT scans of patients between 25-75 years enrolled at a CBCT centre in Bhopal, India. The images were acquired using Sirona's Orthophos SL [70 Kv and 8 mA]. Two oral and maxillofacial radiologists examined all images to evaluate the objectives of the study
Results: The gap or space between the lesion and sinus floor was seen in 48% patients, the lesion contact with the sinus floor was seen in 36% patients, the lesion entered the sinus floor was seen in 16% patients. The prevalence of maxillary sinus mucosa/ thickening in our study increased dramatically as the degree of periapical pathology increased. The relationship between position of root tips with periapical lesion, was also assessed
Conclusion: It can be concluded that there is a strong correlation between maxillary sinus mucosa/ thickening due to periapical pathology
