The name styloid process (SP) was derived from the Greek word “stylos” meaning a pillar. It is a bony, cylindrical, needle-shaped projection, which originates from the posterior-inferior side of the petrous bone, immediately in front of the stylomastoid foramen, and goes obliquely down and forward. When elongated leads to pain and discomfort called Eagle's syndrome. Elongated SP accounts approximately to 4–7% of the population, 4% only are symptomatic.
Cherubism was first described by Jones in 1933 as “familial multilocular cystic disease of jaws.” Renamed as cherubism in 1938 because of classical characteristics of full round cheeks and upward cast of the eyes to the angelic look of the cherubs immortalized by renaissance art. It is characterized by progressive painless bilateral swelling of jaws involving either maxilla or mandible producing chubby face. It is uncommon fibro-osseous disorder of bone. Mutation in the gene encoding SH3-binding protein 2 (SH3BP2) plays a role in the disease. There are indications that the gene SH3BP2 plays a role in regulating the increased osteoblast and osteoclast activities that are seen in normal tooth eruption and point mutations in the gene could cause pathologic activation of osteoclasts. The purpose of this paper is to present the uncommon form of cherubism and to review the clinicoradiographic, histopathologic features and treatment so as to facilitate diagnosis of disease.
Aim:The present study is undertaken primarily to determine if a correlation in the appearance of nutrient canals with hypertension and diabetes exists and to determine whether the presence of nutrient canals can be used as a clue for the detection of hypertensive and diabetic patients.Patients and Methods:A total of 300 subjects were selected from the out-patient department comprising of 100 diabetic patients, 100 hypertensive patients and 100 patients without any systemic diseases as control group. Intraoral periapical radiograph of all these patients were taken for evaluation.Statistical Analysis Used:Statistical analysis of the data was done using the statistical package for the social sciences (SPSS 15.0) using Chi-square analysis. Differences were considered as significant when P ≤ 0.05.Results:Of all these 300 patients, 162 patients exhibited nutrient canals whereas 118 patients didn′t have nutrient canals. Of the 100 patients in Group I, 62 patients exhibited nutrient canals which accounts to 62% prevalence, 64 out of 100 patients in Group II, exhibited nutrient canals which account to 64% prevalence and 72 out of 100 patients in control group exhibited nutrient canals which account to 36% prevalence.Conclusion:As the study showed positive correlation, we conclude same that presence of nutrient canal can be used as an aid to rule out systemic diseases like diebeeis mellitus and hypertension.
Aim: Haller's cells are developmental variants of anterior ethmoidal sinus which are also known as infraorbital ethmoidal cells or orbito ethmoidal cells or maxilla ethmoidal cells. These anatomic variants of sinonasal regions pneumatize inferiorly and medial to the orbital floor and towards the inferior of maxillary sinus. Hence, the present study was to determine the prevalence of Haller's cells using CT PNS images. Objectives: The purpose of the study is to determine the prevalence of Haller's cells according to age and gender, to evaluate the relationship between Haller's cells and maxillary sinusitis and to correlate between Haller's cells and ipsilateral orbital floor dehiscence. Methods: CT PNS images of 60 patients within the age group of 16-75 years were retrieved, screened by a radiologist and analyzed. The data collected were subjected to statistical analysis analyzed with statistical software package, SPSS version 16.0. and p value < 0.05 was considered to be statistically significant. Results: The prevalence of Haller's cells in the present study was found to be 48%. There was no statistically significant association between the presence of Haller cells with respect to age and gender. There was a significant association between Haller cells with maxillary sinusitis and orbital floor dehiscence. Conclusion: This study has attempted to find the prevalence of Haller's cells which will be helpful for dentists in specifying the differential diagnosis for Oro facial pain and maxillary sinusitis.
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.
