The Frequency and Distribution of Idiopathic Osteosclerosis of the Jaw

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 2,211 panoramic radiographs obtained from the patients (915 men and 1,296 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 2008 and 2009.Results:Of 2,211 patients, 135 patients (6.1%) had IO. The prevalence obtained in our study was in the range reported in the literature. IO was detected more often in mandible rather than the maxilla. In addition, mandibular molar localization was the most common localization, and most of the lesions were associated with root apices.Conclusions:In view of the findings, IO can be defined as developmental variations of normal bony architecture, which are unrelated to local stimuli. The lesions can arise at any age, any location with no sex predilection, and IO usually requires no treatment other than diagnosis. Because all these lesions were located in the jaw and could only is detected in panoramic evaluations, this indicates the importance of careful diagnostic evaluation of radiographies in dental examinations.

Idiopathic Osteosclerosis of the Jaws in Turkish Subpopulation: Cone-Beam Computed Tomography Findings

“…Many studies investigated among various populations by different radiographic equipment reported the distribution of IO between % 1.7 and % 31 mostly without gender discrimination and with mandibular posterior predominance (1)(2)(3)(4)(5)(6)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23). The difference in ethnic groups living different geographic regions; having distinctive genetic variations, habits and addictions was implied for one of the reasons of this distribution discrepancy in addition to unstandardized IO description between investigators and difference in radiographic technique of choice (3,6,15,16).…”

“…In Turkish population; IO distribution was reported between 2.4% and 6.1% on the studies performed with panoramic radiography [18][19][20][21] and 4% of 500 patients on a study performed with CBCT (14).…”

“…Even though the etiologic factors of IO formation have not been clearly understood yet; bone reaction related with increased occlusal forces, stimulating effect of residual root fragments and sufficient blood supply, torus-like developmental anatomic variations have been discoursed as possible causes of IO formation (1,5,(13)(14)(15)(19)(20)(21)(22).…”

“…With this radiologic appearance; IO can be differentiated from sclerotic lessions surrounded with radiolucent border like osteoma, osteoblastoma, periapical cemental dysplasia and from the lessions caused cortical expansion like torus and exostosis (7,(16)(17)(18). The distribution of IO was reported between 1.7% and 31% in many studies investigated among various populations by different radiographic equipment (1)(2)(3)(4)(5)(6)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23).…”

Diagnostic considerations while utilizing intraoral periapical radiographs for diagnosing radix entomolaris

“…In mandibular region, it frequently occurs in posterior region when compared to anterior region 5 . It is observed incidentally in radiographs as a well defined radiopacity ranging in size from 2mm to more than 2 cm, and is elliptical, round or irregular in shape 6 . They can be observed at apex of tooth roots or between the teeth roots.…”
