Dental practitioners may encounter various oral mucosal diseases. Oral lesions can be the early manifestation of many systemic diseases. Mucous membrane pemphigoid (MMP) is a chronic, auto immune vesiculobullous lesion involving the mucocutaneous structures. It is important for a dental surgeon to be aware of oral presentations of MMP. Early and accurate diagnosis of this rare clinical entity is essential for the effective management of the lesions which may reduce or lessen disease progression. Present case report highlights the clinical presentations of MMP affecting the oral mucosa along with diagnostic features.

ABSTRACT Localisation of impacted teeth is essential for surgical and orthodontic management. The study objective was to evaluate the prevalence and type of tooth impaction in the jaws using cone beam computed tomography (CBCT). The CBCT records of subjects between 2018 and 2020 were retrieved from our institution archives and examined by two oral radiologists. A total of 760 CBCT scans were evaluated, of which 140 (18.4%) scans had impacted teeth. From the 140 CBCT scans, 216 impacted teeth were identified. Maximum impactions were in the age group of 21–30 years. Third molars were the most commonly impacted teeth (66.2%), followed by canines (23.6%), supernumerary teeth (4.6%), premolars (3.2%), incisors (1.4%), and second molars (0.9%). Among the impacted canines, 53% were buccally impacted, 43% were palatally impacted and other impactions were 4%. Among the third molars, mesioangular impactions were the most frequent (41.2%), followed by horizontal (28%), vertical (16.7%) and distoangular impaction (4.1%). The most frequently impacted teeth were the third molars, followed by canines. Canine impactions were more frequent in the maxilla, while third molar impactions were thrice as common in the mandible compared to the maxilla. Mesioangular third molar impactions were the commonest, followed by horizontal, vertical and distoangular.
