Prevalence of Impacted Teeth in a South Indian Population using Cone Beam Computed Tomography: A Retrospective Study

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.

Mucous membrane pemphigoid presenting as bleeding gums and burning sensation of mouth: a case report

@#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.

Multiple craniofacial osteomas: an isolated case

Osteoma is a benign bony outgrowth of membranous bones and is found mostly on skull and facial bones. In the head and neck region they are commonly seen in the frontoethmoidal regions. The lesions are usually asymptomatic and sometimes may impinge on surrounding areas and cause symptoms. Osteomas may be present in a solitary or multiple sites. The present article reports a case of multiple osteomas of head located in the craniofacial region with imaging details.

Three-dimensional imaging of progressive facial hemiatrophy (Parry-Romberg syndrome) with unusual conjunctival findings

Progressive hemifacial atrophy, also known as Parry-Romberg syndrome, is an uncommon degenerative condition which is poorly defined. It is characterized by a slow and progressive atrophy affecting one side of the face. The onset usually occurs during the first two decades of life. Characteristically, the atrophy progresses slowly for several years, and then it becomes stable. Ophthalmic involvement is common, with progressive enophthalmos which is a frequent finding. Cutaneous pigmentation is common in such conditions, however its extension to the conjunctiva is rarely reported. We report a case of Parry Romberg syndrome with characteristic clinical and radiographic presentation accompanied with rare ocular findings. The clinical features, radiological findings, and differential diagnoses to be considered, and the available treatment options are discussed in this report.

Desmoplastic ameloblastoma: a report of two clinical cases

Desmoplastic ameloblastoma is a relatively rare histological variant of ameloblastoma with specific clinical, radiological, and histological features. Although radiographic examination of ameloblastomas usually reveals unilocular or multilocular radiolucency, desmoplastic ameloblastoma may appearas a mixed radiopaque-radiolucent lesion resembling benign fibro-osseous lesions. Histologically, desmoplastic ameloblastoma is characterized by small nests and strands of “compressed”odontogenic epithelium supported by pronounced collagenized stroma. This report describes two cases of desmoplastic ameloblastoma in the anterior maxilla of a female patient and the anterior mandible of a male patient, mimicking clinically as an odontogenic cyst.
