“…Evangelista et al 13 found that maxillary canines and first premolars showed a high prevalence of dehiscence when they compared the presence of periodontal defects in different malocclusions. Our results showed that, at first the maxillary canine and first premolar suffered from periodontal consequences because of malocclusion and skeletal differences.…”

Objective: To quantitatively evaluate the effects of asymmetric rapid maxillary expansion (ARME) on cortical bone thickness and buccal alveolar bone height (BABH), and to determine the formation of dehiscence and fenestration in the alveolar bone surrounding the posterior teeth, using conebeam computed tomography (CBCT). Materials and Methods: The CBCT records of 23 patients with true unilateral posterior skeletal crossbite (10 boys, 14.06 6 1.08 years old, and 13 girls, 13.64 6 1.32 years old) who had undergone ARME were selected from our clinic archives. The bonded acrylic ARME appliance, including an occlusal stopper, was used on all patients. CBCT records had been taken before ARME (T1) and after the 3-month retention period (T2). Axial slices of the CBCT images at 3 vertical levels were used to evaluate the buccal and palatal aspects of the canines, first and second premolars, and first molars. Paired samples and independent sample t-tests were used for statistical comparison. Results:The results suggest that buccal cortical bone thickness of the affected side was significantly more affected by the expansion than was the unaffected side (P , .05). ARME significantly reduced the BABH of the canines (P , .01) and the first and second premolars (P , .05) on the affected side. ARME also increased the incidence of dehiscence and fenestration on the affected side. Conclusions: ARME may quantitatively decrease buccal cortical bone thickness and height on the affected side.

“…13 The total root length of each tooth was determined from axial and crosssectional images at the buccal and palatal surfaces. If the images showed no cortical bone around the root in at least three sequential views, the defects were recorded as dehiscence and fenestration ( Figure 5).…”

“…Regarding the upper canines and first premolars, Al-Belasy and Hairam 2) reported that infection can easily spread to the infraorbital space. Meanwhile, regarding the frequency of perforation of the labial wall of the maxillary alveolar process, Evangelista et al 6) reported rates of dehiscence and fenestration of 18.73 and 17.87%, respectively, for canines and 18.45 and 18.06%, respectively, for first premolars. In other words, with the syringe method for calcium hydroxide paste, if root canal configuration is inappropriate, then, anatomically, leakage from the root apex and displacement into the infraorbital space can easily occur.…”

Two patients requiring surgical management for leakage of calcium hydroxide paste from a root canal into the infraorbital space are reported. A paste root canal treatment material used at the time of maxillary root canal treatment had leaked out of the root canal in both patients. Computed tomography confirmed displacement of the root canal treatment material into the soft tissue, with extension into the infraorbital space. In both cases, foreign body removal was performed. Root canal treatment using a calcium hydroxide paste should be performed carefully without strong pressure.

“…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. 21 A few studies 9,25,26 have analyzed dehiscences and fenestrations by CBCT in different malocclusion groups and normal populations. However, no data were available for patients with clefts.…”

“…They found that dehiscences were more prevalent than fenestrations and were associated with half the teeth (51.9%); the proportion was 36.5% for fenestration. 26 Similarly, dehiscences and fenestrations were assessed with CBCT in skeletal Classes I, II, and III malocclusions. 25 The Class II group had a greater prevalence of fenestrations, and dehiscences were seen with a high frequency in the mandibular incisors of all groups.…”

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.)
