Evaluation of different Apexification treatments of teeth with immature apices and apical periodontitis on the fractal dimensions of trabecular bone

Abstract

The aim of the present study was to investigate in the fractal dimension (FD) time‐dependent changes of periapical bone after two different apexification treatments in teeth with immature apices and apical periodontitis. This study included 55 cases treated with apexification. Cases were divided into two groups: a calcium hydroxide group and a mineral trioxide aggregate group. In each case, the lesion area was evaluated by fractal analysis on periapical radiographs obtained before and 1‐year after treatment via Image‐J program. The FD of each region of interest on the radiographs was calculated using the fractal analysis method. The data were statistically analysed. In both groups, the FD values increased compare to initial at 1‐year follow‐up after treatment (P < .05). There was no statistically significant difference between the groups in terms of the time‐dependent increase in FD values (P = 0.118). In the present study, time‐dependent changes in FD were independent of the apexification method.

Outcome of single‐visit root canal treatment with or without MTAD: A randomized controlled clinical trial

“…The present study presented no significant correlation in the FD values regarding gender, consistent with the previous studies (Ugur Aydın et al, 2019;Ince Yusufoglu et al, 2021) except Ling et al (2014) who reported that the FD significantly differed by age and gender. The same radiography technique and exposure settings for the initial and postoperative radiographs were used in the present study to be consistent.…”

“…However, there have still been concerns about CBCT due to higher costs and radiation exposure during diagnosing of apical lesions. In the present study, periapical radiography was preferred for diagnosis, treatment, and postoperative evaluation by PAI and FA (Ugur Aydın et al, 2019; Ince Yusufoglu et al, 2021). According to the PAI evaluation, the present study's healing outcome was 90.4%.…”

“…The dentomaxillofacial radiologist analysed the FD of each periapical radiograph. Regions of interest (ROI) were selected as 64 × 64 pixel size squares located 2 mm from the radiographic apex on preoperative and postoperative radiographs (Figure 3) as described in a previous study (Ince Yusufoglu et al, 2021). By this way, for each tooth, the location of the ROI was kept the same on both radiographs.…”

Assessment of bone quality of apical periodontitis treated with MTA plug and regenerative endodontic techniques

“…For example, a study reported that in healed cases, FD values increased significantly, compared with baseline values, 1 year after re‐treatment [32]. Similarly, Yusufoğlu et al[33] showed that FD values increased at 1‐year follow‐up period after MTA plug and calcium hydroxide apexification treatment. On the contrary, a study reported that the FD decreased after clinically successful endodontic treatment [34].…”

Anatomical assessment of the trabecular structure of the alveolar bone in periodontal disease by fractal analysis method

“…It was investigated how the fractal dimensions of trabecular bone of the periapical bone showed a prospective morphological change after two different apexification treatments in teeth with apical periodontitis. The lesion area of the case was evaluated with the fractal analysis method on the periapical radiographs obtained before the treatment and 1 year after the treatment with the Image-J program (18). In addition, Tosun et al calculated the fractal size of abnormal tissue areas around the root apex on periapical radiographs taken before and after treatment in a retrospective study of 50 patients.…”
