Lesions classified as Cemento-osseous dysplasia (COD) largely encompass three different sub-groups: Florid, focal and periapical lesions. Presentation is said. Cemento-osseous dysplasia (COD) is a benign condition of the jaws that may arise from the fibroblasts of the periodontal ligaments. It is most common in. Periapical cemento-osseous dysplasia (COD) is a very rare benign lesion arising from a group of disorders which are known to originate from undifferentiated.

First, the sample of cases was subject to referral bias. Head Neck Pathol ;2: The symmetrical radiolucency was remarkably reduced as more mineralization occurs at whole mandibular associated lesions. In the third patient, secondary osteomyelitis developed.
Periapical Cemento-osseous Dysplasia: Clinicopathological Features
J Oral Sci It can be diagnosed by radiographic appearance. Lam is associate professor and head, discipline of oral and maxillofacial radiology, faculty of dentistry, University of Toronto, Toronto, Ontario. In this case report an FCOD is presented, which is located between the first premolar and the second molar on the left side mandible of a year-old female patient.
The therapeutic approach to periapical COD is conservative, and consists of periodic clinical and radiographic check-ups 16 ; it has been suggested that resection of the lesion may be reserved for cases with an obvious state of chronic inflammation, or those that are characterized by repeated abscesses, which may involve the risk of developing chronic sclerosing osteomyelitis.
A year-old white Caucasian woman was referred for evaluation of the mobility of teeth Distinguishing features of focal cemento-osseous dysplasia and cemento-ossifying fibromas.
The panoramic radiograph taken 1 year after the operation Click here to view. Histological appearance of FCOD showed large sheets or fused globules of cemento-osseous tissue, which may be fused to the roots of one or more teeth or may lay separately. S50 – 70 A clinical and histopathologic study of fifteen cases. Minor radiolucency could be recognized around the roots while the high dense deposit within the bone is obvious at the mandibular associated lesions.
Florid cemento-osseous dysplasia may be familial with an autosomal dominant inheritance pattern, but there are only a few examples in the literature in which the familial pattern has been confirmed.
This article has been peer reviewed. Diagnosis is important so that the treating doctor does not confuse it for another periapical disease such as rarefying osteitis or condensing osteitis.
The diagnosis, treatment and 1 year follow-up after surgery are reported. This deposition may occur because of poor vascularity of the altered dysplastic tissue when there is communication with the oral cavity. In the first or osteolytic phase, a circular radiolucent lesion is visible at the apex of the root; in the second or cementoblastic stage, cementoblastic activity increases and, consequently, cemento-ossseous of cement begin to form, so that the radiolucent lesion assumes a mixed appearance.
Conflict of interests None declared. Am J Clin Pathol Cememto-osseous A clinical-pathologic study of thirty-four cases. Extra-oral examination was within normal limits. OPT image shows the bilateral radiolucent-radiopaque lesions around the apical thirds of the mandibular teeth. A clinical-pathologic study of thirty-four cases. Differences in histopathological nomenclature.

The young age of some individuals in the current study may reflect the radiographic basis of the study. Early-stage lesions have presented as periapical radiolucent defects that subsequently developed minute radiopacities. Cemento-osseous lesions are a complex sysplasia of lesions of similar histological appearance.
Speight PM, Carlos R. Commonly, no treatment is required and only regular follow-up examinations are advised 7. A complete or partial radiolucent rim was noted in a few reports 12,13,22 and a sclerotic border has been less frequently reported 2,14,22 Fig.
The definitive diagnosis for this case was periapical COD. FCOD is, usually, found during routine radiographic examination.
Periapical Cemento-osseous Dysplasia: Clinicopathological Features
The data were analyzed using SPSS software version Depending on the patient’s preference, a mandibular overdenture could later be provided. The lesion can be seen opposite the mandibular left first molar in a standard occlusal radiograph of the mandible c and a transverse computed tomography image d. There is no treatment necessary for any type of COD. Ortopantomography Figure 2followed by cone-beam computed tomography; these revealed a large area of calcified dysplasia, oval in shape, the longer axis being 3 cm, extending from the root-apex of the teeth to the inferior underlying mandibular cortical bone.
None of her family reported to have similar conditions. The WHO histological typing of odontogenic tumours. The etiology and pathogenesis of FCOD are unknown. Cemento-psseous cementum-like substances were mainly acellular in structure; there were no signs of free hemorrhage or osteoclastic activity. Demographic and clinical data, radiographic findings and final diagnoses were collected and analyzed to determine typical characteristics.
