Fractal dimension, lacunarity, and bone area fraction analysis of peri-implant trabecular bone after prosthodontic loading.

Objectives: To assess the structural alterations in peri-implant bone occurring 5 years after prosthodontic loading in panoramic radiography (PR).

Methods: PR images of 44 mandibular and 33 maxillary implants along with 42 healthy control teeth taken before and 5 years after prosthodontic loading were included. Two regions-of-interest (ROI) were selected from mesial and distal surrounding bone of each implant and tooth.

Comparison of quantitative radiomorphometric predictors of healthy and MRONJ-affected bone using panoramic radiography and cone-beam CT.

Objectives: To determine the most distinctive quantitative radiomorphometric parameter(s) for the detection of MRONJ-affected bone changes in panoramic radiography (PR) and cone-beam CT (CBCT).

Methods: PR and sagittal CBCT slices of 24 MRONJ patients and 22 healthy controls were used for the measurements of mandibular cortical thickness (MCT), fractal dimension (FD), lacunarity, mean gray value (MGV), bone area fraction (BA/TA), trabecular thickness (Tb.Th), trabecular separation (Tb.

Prospective randomized single-blind study of post-operative bleeding after minor oral surgery in patients with cirrhosis.

Background/aims: The management of patients with cirrhosis requiring dental extractions is complicated due to an increased risk of post-operative bleeding. Topical hemostatic agents are usually required to control bleeding in these cases, as an adjunct to systemic measures of hemostasis. The aims of this randomized, prospective, single-blind clinical study are twofold.

Survey on Retention Protocols Among Turkish Orthodontists.

Objective: The purpose of this study was to identify general retention protocols practiced by Turkish orthodontist and to compare the results obtained with those of similar studies in Western countries.

Methods: The Web-based survey consisted of 29 questions: 3 to identify the demographic characteristics of the participants and 26 to examine how orthodontists manage the retention phase. Data was interpreted by descriptive statistical methods such as the median test, the Mann-Whitney U-test and logistic regression analysis.
