Proton pump inhibitors and mandibular bone quality: A preliminary study

OpenAlex English

OBJECTIVES: Proton pump inhibitors (PPI) provide a long-lasting anti-acidic effect by inhibiting the proton pump, and they are one of the most commonly prescribed drugs worldwide. PPIs adversely affect the bone structure via deficiency of vitamins and minerals. The aim of this study was to investigate the possible PPI-induced bone changes in the mandible on panoramic radiographs with the methods of fractal analysis and panoramic morphometric indices. METHODS: Panoramic radiographs of 402 patients were used (201 PPI users, 201 control group). Fractal analysis was performed on 4 regions of interests (ROI): 1- upper part of the ramus, 2- angulus, 3- anterior of the mental foramen, 4- distal of the middle ramus. Also, the panoramic mandibular index (PMI), mandibular cortical width (MCW), and Klemetti index (KI) were performed on radiographs. RESULTS: > 0.05). Males were severely affected than females. CONCLUSIONS: Osteoporotic changes were detected in the trabecular and cortical bone in the mental foramen region in PPI users with fractal analysis and morphometric indices, while there were no differences for mandibular ramus and angulus regions according to fractal analysis.
