Abstract

Prevalence of Cortical Bone Fenestration and Sinus Membrane Thickening in Association with Endodontic Infection. A review of CBCT scans.

Introduction

Although a systemic disease due to the spread of endodontic infection is very rare or non-existing, the dissemination of endodontic infection into intimately associated anatomical structures such as alveolar bone and maxillary sinus are known (1-4). In this study we examined and reported the prevalence of maxillary sinus involvement and cortical bone fenestration during an endodontic infection. The study also evaluated and presented association between factors such as (type of teeth, systemic diseases, patient’s age, and gender) and radiographic presentation of endodontic lesions (periapical radiolucent lesion (PARL), sinus membrane thickening (SMT), bone fenestration (BF), sinus floor fenestration (SF).

Material and Methods

This study utilized existing cone beam computed tomography (CBCT) electronic records from the West Virginia University Department of Endodontics. We measured and recorded prevalence data for endodontic related lesions such as periapical radiolucent lesion (PARL), sinus membrane thickening (SMT), cortical bone fenestration (BF), and sinus floor fenestration (SF). We also report the correlation between independent factors (type of teeth, systemic diseases, patient’s age, and patient’s gender) and the endodontic lesions described above.

Results

Looking at the prevalence data, result reveals a 76% and a 71% prevalence in SMT and sinus floor/root apex association (SR) respectively. There is also a 45% prevalence in PARL. When examining correlations, the result found an increase in PARL in teeth with recurrent infection (P60-yrs) and an increase in PARL and BF (P

Conclusion

In conclusion, our study found a high prevalence of SMT and higher prevalence of sinus floor/root apices in contact. There is a correlation between pmr and an increase in BF; between patients 60-yrs and older an increase in BF (P
