Delayed Diagnosis of Unilateral Mandibular Condylar Fracture in a Posterior Edentulous Patient

Background. Fractures of the mandible are common in elderly patients, and among them, condylar fractures are the most frequent type. A change in occlusion is the most common physical finding in patients with fractures of the mandible. Therefore, it is challenging to identify mandibular fractures in posterior edentulous patients due to the lack of posterior occlusal contacts. It is crucial to do radiological investigations in such patients to exclude fractures. Case Presentation. This article describes a case of delayed diagnosis of a unilateral mandibular condylar fracture for a week’s duration and treating the condition as temporomandibular pathology in a posterior edentulous, 52-year-old patient. Conclusion. This clinical case highlights the importance of radiological investigations and occlusal analysis for early diagnosis of condylar fractures, particularly in posterior edentulous patients, lacking posterior occlusal contacts

Morphology of palatally impacted canines: a case-controlled cone-beam volumetric tomography study

Introduction The aim of this study was to investigate the relationships between an apical curvature or a hook and the crown/root ratio in subjects with and without palatally impacted maxillary canines. Methods An experimental group of 44 patients (17 boys, 27 girls; mean age, 13.6\ua0years) with 59 palatally impacted maxillary canines was selected from the records of patients referred to a radiology practice for cone-beam imaging. If a patient had bilateral palatally impacted canines, 1 canine was randomly selected for analysis. The palatally impacted canine group was matched for age and sex with 49 normal subjects (25 boys, 24 girls; mean age, 13.2\ua0years) with 98 canines. Cone-beam DICOM files were imported into In\ua0Vivo imaging software (version 5.3; Anatomage, San Jose, Calif) for analysis. The angulations and linear variables of the maxillary canines were measured by using the software measurement tools. Chi-square and independent t tests were used to test for differences between the groups. Results The presence of a hook at the apical third and other root curvature were significantly different between the 2 groups (P\ua

Comparison of topical tacrolimus and clobetasol in the management of symptomatic oral lichen planus: A double-blinded, randomized clinical trial in Sri Lanka

AimOral lichen planus (OLP) is a common, chronic inflammatory disease of the oral mucosa. Although several studies have shown the efficacy of different treatment modalities, a definitive cure has not yet been established. The present trial compares the effectiveness of topically-applied clobetasol and tacrolimus in the symptomatic management of OLP.MethodsA randomized, comparative, double-blind study with 68 patients (43 females, 25 males; mean age: 46.76 years) was undertaken. Patients were randomly divided into two groups of 34 patients each to receive topical tacrolimus 0.1% cream or clobetasol propionate 0.05% cream for 3 weeks.ResultsAfter 3 weeks of treatment, the mean pain score dropped by 1.59 (right) and 1.53 (left) in the tacrolimus group, while in clobetasol group these values were 0.94 and 0.85, respectively. The mean scores for clinical appearance reduced by 1.18 (right) and 1.0 (left) in the tacrolimus group compared with a reduction of 0.5 and 0.26, respectively, in the clobetasol group. These reductions were statistically significant (P ConclusionThe results suggest that tacrolimus 0.1% cream is an effective alternative to topical steroid and can be considered a first-line therapy in OLP. However, further studies are needed to confirm the effectiveness of this treatment before it is recommended for use in clinical practice.<br/

Linear and Volumetric Analysis of Maxillary Sinus Pneumatization in a Sri Lankan Population Using Cone Beam Computer Tomography

Objective. The objectives of this study were to evaluate the linear and volumetric measurements of the maxillary sinus in relation to sex and side on cone beam computer tomographic (CBCT) images in a Sri Lankan population. Methods. A total of 20 sets of CBCT images selected from the database at the Division of Oral Medicine and Radiology, Faculty of Dental Sciences, University of Peradeniya, Sri Lanka, were evaluated. Linear measurements were obtained in a craniocaudal (height), anteroposterior (length), and mediolateral (width) dimensions. Volume was computed by using the same data using a computerized 3D modeling software developed for 3D measurements and calculations. Results. The maximum mean craniocaudal dimension was at the level of the 1st and the 2nd molar tooth bilaterally. The largest average craniocaudal, mediolateral, and anteroposterior extensions of the maxillary sinus using CBCT were 31.71±5.44 mm, 21.28±5.09 mm, and 32.92±4.31 mm, respectively. The differences between the sides and sex showed no statistical significance (P>0.05), except for the maximum average value in craniocaudal dimension which showed a statistically significant difference in relation to gender (P=0.02). Conclusion. There is no significant difference in the largest average craniocaudal, mediolateral, and anteroposterior extensions of the maxillary sinus when gender and side were compared. However, the maximum average value in craniocaudal dimension had a statistically significant difference in relation to gender. This study provides valuable knowledge of the anatomical dimensions of the maxillary sinus which may help clinicians in treatment planning
