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.

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.
