Abstract Objectives: To determine the prevalence of idiopathic osteosclerosis IO in the jaw by radiographic evaluation and to investigate the relationship between the findings in relation to age, gender, and localization. Methods: The study included 2, panoramic radiographs obtained from the patients men and 1, women whose ages ranged from 10—77 and who visited the Department of Oral Diagnosis and Radiology in the Faculty of Dentistry, Erciyes University between and

Corresponding author. E-mail : moc. Materials and Methods Seven hundred and fifty patients were examined for the presence of IO in the jaw bone. After a thorough clinical examination, radiographic examination was done using OPG. Age specified by WHO were used 5, 12, 15, and The data collected was than tabulated and subjected to descriptive statistics and chi square test.
Results Among the total study population 89 The maximum number of IO cases cases was seen among the age group of y, 33 Keywords: Idiopathic osteosclerosis, Jaw bone, Oral health, Radio opacity Introduction Idiopathic osteosclerosis IO is a benign lesion which is mostly asymptomatic and come into limelight only when the radiographs are taken.
Dental literature describes this lesion with various names dense bone island, idiopathic osteosclerosis, enostosis and focal periapical osteopetrosis [ 1 ]. It can also be observed at various other sites in the skeleton such as pelvis, femur and other long bones [ 2 ]. These are areas with increased radio density of unknown aetiology and is not attributed to any dysplastic, inflammatory, neoplasia, or systemic disorder, it is not to be associated with detectable cortical expansion [ 3 ].
There is a need to differentiate IO from various other lesions that are observed by the dentists such as periapical cemental dysplasia, submandibular calculus, torus, exostosis, osteoma, odontoma, and condensing osteitis CO of dental origin associated with low-grade, chronic inflammation of the bone around the tooth apex as well as from soft-tissue lesions such as tonsilloliths, phleboliths, and sialoliths that may project as radiopacities in panoramic radiographs [ 4 ].
Although the aetiology of IO is unclear, but it may involve internal stress and sufficient blood supply to form bone masses in the mandible. Araki M et al. The study was carried out during the span of 6 months from June to December Patient who were willing to participate in the study and were falling in the age specified by WHO 5, 12, 15, and [ 6 ] were included in the study as per selective sampling.
Patients who had any source of pulpal infection, any known systemic illness, radiographic evidence of developmental anomalies or pathologies of the teeth and jaws were excluded from the study. Based on these criteria patients were examined in each age with equal number of males and females to standardize the comparison for the presence of IO in the jaw bone. Kodak C extraoral imaging system was used for digital OPG.
The digital images were then saved and interpreted.
