Findings of Florid Cemento-Osseous Dysplasia: a Report of Three Cases

ABSTRACT Background Florid cemento-osseous dysplasia (FCOD) is a benign jaw lesion originating from periodontal ligament tissues usually asymptomatic and diagnosed accidentally at routine dental radiographic examination. The purpose of this paper is to report three cases diagnosed as FCOD with their clinical, radiographic and histological findings. Methods Radiologic and clinical symptoms of three cases diagnosed as FCOD are presented. Serum alkaline phosphatase test and biopsy taken from two of the patients are discussed to eliminate the Pagets disease. Results Three patients diagnosed as FCOD and called for routine follow-up. Because of no sign of infection or osteomyelitis, conservative treatment was applied. Conclusions Radiographic examination is significant for the diagnosis of florid cemento-osseous dysplasia, especially in the asymptomatic cases. The roles of the dentist are to ensure the follow-up of the diagnosed patients and to take the necessary measures for preventing from the infections.

Traumatic bone cyst mimicking radicular cyst.

Traumatic bone cysts were first defined by Lucas and Blum in 1929. It is classified as an intraosseous pseudocyst. They are asymptomatic and are usually seen during routine radiographical examination. According to the 2002 classification of the WHO, traumatic bone cysts are in miscellaneous lesions. This report describes a 16-year-old male patient who had a traumatic bone cyst that mimicked a radicular cyst.

Frank–ter Haar syndrome—additional findings?

Frank-ter Haar syndrome is a genetic disease that is transmitted by autosomal recessive pattern with characteristic features such as megalocornea or glaucoma, a prominent coccyx, heart defects, developmental delays, brachycephaly, a wide anterior fontanel, finger flexion deformities, full cheeks and micrognathia. Dentomaxillofacial features of this syndrome are not well documented in the literature. We present of a 21-year-old male with Frank-ter Haar syndrome and some features that may be linked with this syndrome not reported before in the literature.

THE PREVALENCE OF DENTAL ANOMALIES IN A TURKISH POPULATION

Purpose: The aim of the present study was to investigate the prevalence of dental anomalies in a Turkish population according to the gender and age. Materials and Methods: A retrospective study was performed using panoramic radiographs of 2025 patients (885 males and 1140 females) ranging in age from 9 to 35 (mean age 25.61±10.04) years attending Department of Oral Radiology, University of Istanbul, Faculty of Dentistry. These patients were examined to determine the presence of developmental dental anomalies involving hypodontia, hyperdontia, microdontia, taurodontism and other root anomalies. The incidence of these anomalies were assessed according to the gender and age. Results: Among the 2025 subjects, a total of 96 individuals (42 males and 54 females) showed at least one of the selected dental anomalies (4.74%). Tooth agenesis was the most common dental abnormality (1.77%) followed by taurodontism (1.18%), hyperdontia (0.79%), microdontia (0.54%) and root anomalies (0.44%), respectively. Conclusion: Tooth agenesis is the most common developmental dental anomaly in the studied Turkish population followed by taurodontism.

The Accuracy of New and Aged Mechanical Torque Devices Employed in Five Dental Implant Systems

Purpose Friction-style and spring-style torque wrenches are used to tighten implant abutments and prosthetic screws. The mechanical stability of these torque wrenches is crucial for the implant–abutment connection. The purposes of this study were to assess the performance of five brands (Straumann, Zimmer, Implant KA, Bredent, and Biohorizons) of wrench and to evaluate possible changes in applied torque values of aged wrenches. Materials and Methods Five new and aged wrenches that had been used approximately 250 times in a 1-year period were tested. The torque applied by friction- and spring-style wrenches was measured with a specially designed strain gauge indicator. Descriptive statistics, the one-sample t-test, and the independent-samples t-test were used to analyze values obtained from all torque wrenches. Results The accuracy of new and aged torque devices of all brands except Bredent differed significantly from the target values, but the mean values for aged and new wrenches did not differ significantly from each other (p > 0.05). Values for the spring- and friction-type torque wrenches deviated from the target values by 11.6% and 10.2%, respectively. Conclusion The accuracy of aged torque wrenches is adequate for prosthetic screw tightening, but that of new torque wrenches is unsatisfactory and must be examined carefully before delivery.

Reliability and validity of the Turkish version of the Rapid Estimate of Adult Literacy in Dentistry (TREALD-30)

Abstract Objective: To culturally adapt the Turkish version of Rapid Estimate of Adult Literacy in Dentistry (TREALD-30) for Turkish-speaking adult dental patients and to evaluate its psychometric properties. Material and methods: After translation and cross-cultural adaptation, TREALD-30 was tested in a sample of 127 adult patients who attended a dental school clinic in Istanbul. Data were collected through clinical examinations and self-completed questionnaires, including TREALD-30, the Oral Health Impact Profile (OHIP), the Rapid Estimate of Adult Literacy in Medicine (REALM), two health literacy screening questions, and socio-behavioral characteristics. Psychometric properties were examined using Classical Test Theory (CTT) and Rasch analysis. Results: Internal consistency (Cronbach’s Alpha = 0.91) and test-retest reliability (Intraclass correlation coefficient = 0.99) were satisfactory for TREALD-30. It exhibited good convergent and predictive validity. Monthly family income, years of education, dental flossing, health literacy, and health literacy skills were found as stronger predictors of patients’oral health literacy (OHL). Confirmatory factor analysis (CFA) confirmed a two-factor model. The Rasch model explained 37.9% of the total variance in this dataset. In addition, TREALD-30 had eleven misfitting items, which indicated evidence of multidimensionality. The reliability indeces provided in Rasch analysis (person separation reliability = 0.91 and expected-a-posteriori/plausible reliability = 0.94) indicated that TREALD-30 had acceptable reliability. Conclusion: TREALD-30 showed satisfactory psychometric properties. It may be used to identify patients with low OHL. Socio-demographic factors, oral health behaviors and health literacy skills should be taken into account when planning future studies to assess the OHL in both clinical and community settings.

TOOTH EXTRACTION FROM A PATIENT WITH CAVERNOUS HEMANGIOMA IN MAXILLOFACIAL REGION: CASE REPORT

Hemangiomas are benign vascular tumors which represent a rapid growth pattern followed by the involution phase. Generally, they are located in the soft tissues and are usually diagnosed in the first decade of life. Hemangiomas are mostly asymptomatic and rarely affect jaw bones. Mandible is affected more often than maxilla. If there is no complication present, treatment may not be necessary. Treatment planning of hemangiomas should be done by considering the location and the size of the lesion as well as the proximity to vital anatomical structures. The aim of this case report is to describe the procedures of tooth extraction in a patient who had been diagnosed as having maxillary cavernous hemangioma.

MONOSTOTIC FIBROUS DYSPLASIA PRESENTING IN MAXILLA: A CASE REPORT

Fibrous dysplasia (FD) is a bone disorder in which fibrous tissue replaces normal bone. FD can be monostotic (10%–25%) or polyostotic (50–90%) and is typically diagnosed accidentally on radiographs. Craniofacial lesions are typically unilateral and are diagnosed by clinical assessment and radiographic evaluation. This report describes the case of a 50-yearold female patient who had presented with painless swelling of the right maxilla and was diagnosed with FD. Subsequent bone scintigraphy identified the lesion as monostotic. Based on the patient’s age and the radiographic data, contour correction was performed. However, 1 year after surgery, the lesion regrew and the treatment was repeated.

Evaluation of dental panoramic radiographic findings in edentulous jaws: A retrospective study of 743 patients "Radiographic features in edentulous jaws"

PURPOSE The aim of this study was to determine the frequency of significant panoramic radiographic findings and eventual treatment requirements before conventional or implant supported prosthetic treatment in asymptomatic edentulous patients. MATERIALS AND METHODS A total of 743 asymptomatic edentulous patients were retrospectively evaluated using a digital panoramic system. We analyzed the radiographic findings, including impacted teeth, retained root fragments, foreign bodies, severe atrophy of the posterior maxillary alveolar bone, mucous retention cysts, soft tissue calcifications and radiopaque-radiolucent conditions. RESULTS Four-hundred-eighty-seven (65.6%) patients had no radiographic finding. A total of 331 radiographic findings were detected in 256 (34%) patients. In 52.9% (n=175) of these conditions, surgical treatment was required before application of implant-supported fixed prosthesis. However, before application of conventional removable prosthesis surgical treatment was required for 6% (n=20) of these conditions. CONCLUSION The edentulous patients who will have implant placement for implant-supported fixed prosthesis can frequently require additional surgical procedures to eliminate pathological conditions.
