“…Because CBCT has been shown to be a reliable method for assessing dehiscences and fenestrations, we decided to use these images in cleft patients, a technique that has not been reported previously. Consistent with previous studies 4,5,[18][19][20][21][22][23][24] showing the high reliability of CBCT for 2-D and 3-D measurements, agreement was 100% for the detection of dehiscences and fenestrations. Although Sun et al 12 reported that this method might overestimate the actual measurements, the technique was reported to have the highest sensitivity and diagnostic accuracy for detecting various periodontal defects.…”

“…3 Children affected by CLP have several problems, caused by anodontia, tooth malformation, and a deficiency of soft and hard tissue in the cleft region. 4,5 Reductions in bone levels in the areas adjacent to the cleft region are associated with delayed tooth formation and eruption, anatomical defects, and problems with orthodontic movement. 6 Today, one of the best ways of imaging the alveolar bone is cone beam computed tomography (CBCT).…”

Objective: To evaluate the presence of dehiscence and fenestration defects around anterior teeth in the cleft region and to compare these findings with the noncleft side in the same patients using cone beam computed tomography (CBCT). Materials and Methods: CBCT scans of 44 patients (26 males, 18 females; mean age, 14.04 6 3.81 years) with unilateral cleft lip and palate (UCLP) were assessed to define dehiscences and fenestrations of the anterior teeth in both cleft and noncleft sides of the UCLP patients and a control group of noncleft patients (51 patients; 21 males, 30 females; mean age, 14.52 6 1.16 years). Data were analyzed using Pearson's x 2 and Student's t-test. Results: The prevalence of dehiscences at the maxillary central incisors, lateral incisors, and canines teeth were 43.2%, 70.6%, and 34.1% on the cleft side and 22.7%, 53.1%, and 27.3% on the noncleft side of UCLP patients, and 13.7%, 7.8%, and 13.7% in controls, respectively (statistically no difference between the sides of cleft patients). The cleft patients had a statistically significantly higher prevalence of dehiscences than did the controls on both the cleft and noncleft sides (P , .05), except for the maxillary central incisors. Fenestrations for these teeth were significantly more common on the cleft side in UCLP patients compared with controls (P , .05), whereas the difference for maxillary lateral incisors was not statistically significant. Conclusions: Patients with UCLP showed a higher prevalence of dehiscence and fenestration defects around the maxillary anterior teeth. (Angle Orthod. 2016;86:431-436.)

“…To our knowledge, no previous study investigated the bone support of the teeth in patients affected by cleft lip and palate (CLP) using cone-beam computed tomography (CBCT). CBCT technology facilitates true (1:1 size) images without magnification and shows high intraobserver and interobserver reproducibility compared with conventional radiographs; [13][14][15] thus, it is important to assess the alveolar bone loss of the teeth adjacent to the cleft area using CBCT. The aim of this study was to assess the bone support of teeth adjacent to the cleft region in patients affected by UCLP using CBCT and to provide more specific and detailed data regarding cleft-affected teeth.…”

Objective: To assess the bone support of the teeth adjacent to a cleft using cone-beam computed tomography (CBCT). Materials and Methods: The CBCT scans of 31 patients with unilateral cleft lip and palate (UCLP) were assessed. The data for teeth neighboring the cleft were compared with those of contralateral noncleft teeth. For each tooth analyzed, the distance between the cementoenamel junction (CEJ) and the bone crest (AC) at the buccal side was measured as was the thickness of the buccal bone level at 0, 1, 2, and 4 mm. Results: The bone thicknesses of the central teeth at the cleft region at the crest and 2 mm apically were statistically significantly thinner than that of the central incisor at a noncleft region. The CEJ-AC distance for central teeth at the cleft region was higher than that for central teeth in a noncleft region. Conclusions: Subjects with UCLP showed reduced bone support at teeth neighboring the cleft compared with controls. This may cause some problems during orthodontic treatment.

“…The measurements of CA, GA, AA and AD were studied to evaluate the dimensional differences of dentate and edentate patients in different populations, previously. 7,19 In these studies, significant differences were found between males and females. For this reason, the present study enrolled the same number of females and males among the patients with BRONJ and control group.…”

“…5 Various skeletal radiographic features related to BRONJ in panoramic and conventional periapical radiographs, CT, nuclear bone scanning and MRI have been defined. 4 The condyle angle (CA), gonial angle (GA), antegonial angle (AA), antegonial depth (AD), mandibular cortical index (MCI), bone quality index (BQI), 6 ramal height (RH) and condylar height (CH) 7 values have been used to observe different morphological conditions on two-dimensional (2D) radiography. But, for the evaluation of the MCI and BQI of patients with BRONJ, CBCT has allowed for the accurate display of the vertical and buccal-lingual dimensions as well as the important mineral density of the mandible.…”

Objectives: The aim of this study was to compare the morphological differences in the mandible between patients with bisphosphonate-related osteonecrosis of the jaw (BRONJ) and healthy individuals and to detect the correlation between these parameters on panoramic radiography and CBCT. Methods: The CBCT and panoramic images of patients with BRONJ (n 5 32) and control groups (n 5 32) were included in the study. All the comparisons were analyzed between the osteonecrosed and healthy sides of patients with BRONJ and control group. The panoramic radiographs were used to measure the values of the condyle angle, gonial angle, antegonial angle, antegonial depth, condylar height and ramal height. The mandibular cortical index (MCI) and bone quality index (BQI) were also examined on cross-sectional scans of CBCT images. Results: There were significant differences in the MCI (p 5 0.014) and BQI (p 5 0.021) between the left and right side of the BRONJ group and also between the osteonecrosed side of the BRONJ and control group (p , 0.0001). No significant difference was found in other comparisons. Conclusions:The outcomes of the present study indicate that bisphosphonates influenced some internal morphological changes in the mandible. These changes may be a reason of BRONJ. But, these changes are not reflective of the measured values obtained using panoramic radiographs on the external morphology of the mandible.
