Prevalence and characteristics of supernumerary teeth: A survey on 7348 people

WOS: 000218606600007PubMed: 25984466Objective: The aim of the present study was to determine the prevalence of supernumerary teeth with by evaluating a large group of adult patients in Turkey and to investigate the characteristics of supernumerary teeth with their complications and treatment options. Study Design: This descriptive and retrospective study was carried out in 7348 adult patients aged over 18 years (3212 females and 4136 males). The characteristics of the supernumerary teeth were noted and the diagnosis was made during clinical and radiographic examination with the help of panaromic, periapical, and occlusal radiography. Information on the demographic variables for each patient, including age and gender, were colleceted. Materials and Methods: All supernumerary teeth were classfied under several titles such as location, position, morphology, eruption, clinical complications, and treatment protocols. The data obtained were subjected to statistical analysis. Chi-squared test was used to determine differences in distribution of supernumerary teeth when stratified by gender. The statistical significance was established by confidence interval of 95% (P % 0.05). Results: 123 (2.14%) affected patients (69 females and 54 males) were observed with a female:male ratio of 1.28:1 (P < 0.05). One hundred and fifty-six supernumerary teeth were detected in all affected patients. Conclusion: Supernumerary teeth may be observed in adults patients with a similar frequency (2.14%) as in children and young adolescents, and clinicians should take measures and examine all patients carefully even at older ages

Reduction of isolated zygomatic arch fractures using dental instrument: Report of 2 cases and review of the literature.

To assess the effectiveness of a dental instrument for reduction of isolated zygomatic arch fractures. Two patients were admitted to our clinic representing isolated unilateral zygomatic arch fracture. The common presenting complaints were pain, swelling and difficulty in mouth opening. Fractures were confirmed with plain radiography and computerized tomography. The fractures were reduced with upper buccal sulcus approach by dental instrument. Patients achieved satisfactory maximum mouth opening within 10 days. At follow up after 6 months, there was complete healing without any complication. This procedure is cost effective, time saving, safe and effective to manage isolated zygomatic arch fractures under local anaesthesia with satisfactory outcomes

Evaluation of IL-32 levels in gingival tissue and serum of experimental periodontitis model

Aim: Interleukin (IL)-32, a recently discovered proinflammatory cytokine, is demonstrated in several infectious diseases. The goal of this study is to investigate the levels of IL-6, IL-10 and IL-32 in gingival tissue and serum of rats with experimental periodontitis. Material and Methods: Experimental periodontitis was induced by placing a silk ligature around the cervix of both sides of mandibular first molars in each male rat except for control group (Group 1). Thirty male Wistar albino rats were randomly divided into three groups of ten animals each as experimental periodontitis groups (Group 2, ligated for seven days; Group 3, ligated for fourteen days) and periodontally healthy control group (Group 1). At the end of experimental period, rats were sacrificed, and histomorphometric analyses were performed on the mandibles. IL-32, IL-10 and IL-6 levels were measured in gingival tissue and serum samples by ELISA. Results: Alveolar bone and attachment loss were statistically higher in all experimental groups than those in control group (P<0.001). It was found that the levels of IL-32 and IL-6 (P<0.01) and IL-10 (P<0.05) in gingival tissues were higher in Groups 2 and 3 than those in Group 1 except for IL-32 and IL-10 levels in Group 3. There was a positive correlation between levels of IL-32 and IL-6 in the serum and gingival tissues in all groups (P<0.05). Conclusion: The present results reveal that IL-32 values are locally increased in periodontitis. Proinflammatory cytokines properties, which are linked to periodontal tissue destruction, are also associated with IL-32
