Effects of cleft lip and palate on the development of permanent upper central incisors: a cone-beam computed tomography study

WOS: 000362967200015PubMed: 25548146Objective: The aim of this study was to evaluate 1. the differences among the cleft sides of unilateral cleft lip and palate (UCLP) patients, non-cleft sides of the same UCLP patients and well matched control patients in the root development and position of permanent upper central incisors and 2. possible gender differences. Materials and methods: The study sample consisted of 40 patient (20 males and 20 females; mean age: 14.84 +/- 3.2 years) with non-syndromic UCLP patients, and 40 control patients (20 males and 20 females; mean age: 13.38 +/- 1.6 years). Cone-beam computed tomography (CBCT) images were taken off from all patients. All tomographs were obtained in supine position by using CBCT (NewTom 5G, QR, Verona, Italy). Results: Significant smaller root volume of central incisor was observed on the cleft side than on the non-cleft side of UCLP patients (P 0.05). There were no statistically significant gender differences in any linear, angular, or volumetric measurements (P > 0.05). Only the root volume of the cleft side was smaller in females than in males (P < 0.05). Conclusions: In general, root volumes of central incisors on the cleft side were 12.15 per cent smaller than non-cleft side. Root development of the central incisor was much more influenced by the cleft in females than in males

Evaluation of mandibular transverse widths in patients affected by unilateral and bilateral cleft lip and palate using cone beam computed tomography

Objective: To evaluate the mandibular dental, alveolar, and skeletal transversal widths in patients affected by unilateral (UCLP) and bilateral (BCLP) cleft lip and palate and to compare the findings with a well-matched normal occlusion sample using cone beam computed tomography images.

Assessment of the soft tissue thickness at the lower anterior face in adult patients with different skeletal vertical patterns using cone-beam computed tomography

Objective: To evaluate and compare the soft tissue thickness values at the lower anterior face among adult patients with different vertical growth patterns using cone-beam computed tomography

Condylar and ramal vertical asymmetry in adolescent patients with cleft lip and palate evaluated with cone-beam computed tomography

Introduction: The aims of this study were to evaluate condylar and ramal mandibular vertical asymmetry in a patient group affected by unilateral (UCLP) and bilateral (BCLP) cleft lip and palate, and to compare the findings with a well-matched control group with normal occlusion. Methods: The study groups included 20 UCLP patients (12 male, 8 female), 21 BCLP patients (12 male, 9 female), and a control group of 21 subjects with normal occlusion (10 male, 11 female). Measurements of condylar, ramal, and condylar plus ramal heights and asymmetry indexes were examined on cone-beam computed tomography images. One-way analysis of variance was used to determine potential statistical differences among the groups for condylar, ramal, and condylar plus ramal asymmetry index measurements. The post-hoc Tukey HSD test was used to determine individual differences. Results: No investigated group showed a statistically significant sex difference for any asymmetry index (P = 0.05). There was a statistically significant difference between the normal and cleft sides in the ramal height and ramal plus condylar height measurements in the UCLP group (P = 0.004 and P = 0.006, respectively). The Tukey HSD test showed a statistically significant difference between the UCLP and BCLP groups in terms of ramal asymmetry index values (P = 0.018). Conclusions: The ramal height and ramal plus condylar height measurements were significantly lower in the cleft side in the UCLP patients, and there was a statistically significant difference in ramal asymmetry index values between the patients affected by UCLP and BCLP

Bilateral anterior Stafne bone defect mimicking radicular cyst: report of a rare case with a review of the literature

Stafne bone defects (SBDs) are asymptomatic radiolucent lingual/buccal bone lesions of the lower jaw that are frequently caused by soft tissue inclusion. SBDs located on the lingual anterior mandibular body (ASBDs) are rare variants. Sublingual salivary glands are thought to be responsible for ASBDs. However, other structures, such as lymphoid or vascular tissues, might be associated with ASBDs. ASBDs may be confused with other odontogenic or non-odontogenic pathologies because of their location and lower occurrence rate. To date, only one case involving the bilateral anterior mandibular area has been reported in the literature, including both the clinical case and archaeological specimens. The primary aim of our study was to describe a new case of bilateral ASBD in the anterior mandible that was mimicking a radicular cyst. The bilateral ASBD was diagnosed with the help of a three-dimensional cone-beam computed tomography scan, and it presented radiographically as a periapical pathologic defect. An additional aim was to review previously reported cases related to ASBDs
