Ameloblastoma is a benign odontogenic neoplasm which frequently affects the mandible. The term ameloblastoma includes several clinico-radiological and histological types. Apart from the most commonly encountered clinico-pathologic models there are few variants, whose biological profile is unknown or not elicited. The reason for lack of understanding is the scarcity of case report published in the literature. Among the types, unicystic ameloblastoma is the least encountered either it presents as unilocular or multilocular radiolucency, but peculiar radiographic presentation of multilocular radiolucency in posterior mandible with unilocular radiographic appearance crossing the midline is extremely rare, which has not been reported yet. Here we report a distinctive case of mural unicystic ameloblastoma of mandible in a 17-year-old-girl with the radiographic presentation as mentioned above.
Pyknodysostosis is a rare autosomal recessive disorder characterized by the post natal onset of short limbs, short stature, and generalized hyperostosis along with acro-osteolysis with sclerosis of the terminal phalanges, a feature that is considered essentially pathognomonic. Other features include persistence of fontanelles, delayed closure of sutures, wormian bones, absence of frontal sinuses, and obtuse mandibular gonial angle with relative mandibular prognathism. We report a case of 17-year-old girl who presented with a chief complaint of retention of deciduous teeth. General physical examination demonstrated short stature, frontal and parietal bossing, depressed nasal bridge, beaked nose, hypoplastic midface, wrinkled skin over the finger tips, and nail abnormalities. Radiographs showed multiple impacted permanent and supernumerary teeth, hypoplastic paranasal sinuses with acro-osteolysis of terminal phalanges, and open fontanelles, and sutures along with wormian bones in the lambdoidal region.
Odontoameloblastoma is a rare neoplasm of odontogenic origin in which there is proliferation of tissue of the odontogenic apparatus in an unrestrained pattern including complete morphodifferentiation, apposition and even calcification. Till date, around 20 cases have fulfilled the histologic criteria of the current World Health Organization histologic classification of odontogenic tumors. Review of literature from 1944 to 2011 reveals only four reported cases in the anterior mandible. Here, we report a case of odontoameloblastoma in the anterior mandible in which plexiform ameloblastoma was associated with compound odontoma forming an unusual combination.
This study aims to investigate the prevalence, morphology and elongation pattern of elongated styloid process in the population of Central Kerala and its relation to age and gender. ` 500 digital panoramic radiographs were collected from the archives of Department of Oral Medicine & Radiology, Mar Baselios Dental College taken during 2017-2020. Only those radiographs of patients within age group of 20-60 years and showed styloid processes of both sides with no pathologies in the required structures were included in the study. Radiographs with magnification and positioning errors were excluded. The collected data was entered in an Excel spreadsheet and analyzed using statistical analysis software-SPSS 16.0. The data was analyzed using chi square test and one way ANOVA. The average length of right and left styloid processes were 25.61±6.25mm & 25.88±6.67 mm respectively. The study showed that there is a progression in the length of right styloid process with advancing age. In this study females had a longer styloid process compared to males. A predominance of type I elongation is seen in both right and left sides.: The best protection is early detection. Presence of elongated styloid process is an incidental radiographic finding. However adequate and prompt diagnosis can lead to elimination of associated complications. This study focuses on detection of elongated styloid processes and comparison of length and identification of elongation patterns among right and left sides. These parameters and patterns may help the clinicians to distinguish between normal and elongated styloid processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
