ABSTRACT
Occurrence of central mucoepidermoid carcinoma within the jaw bones from aberrant salivary tissues is extremely rare and accounts for 2%-4% of all central mucoepidermoid carcinoma. Mandible is more commonly affected than maxilla in a ratio of 2:1. The origin of mucoepidermoid carcinoma is controversial and questionable. Central mucoepidermoid carcinoma is frequently misdiagnosed radiographically and clinically as a benign odontogenic tumor or cyst. Hence, it is important to detect malignant signs and histopathological feature of central mucoepidermoid carcinoma of the mandible to confirm the diagnosis. This paper reports a case of central mucoepidermoid carcinoma of the mandible in a 56-year-old patient with review of literature.
ABSTRACT
OBJECTIVES: The present evaluate the feasibility of Computed tomography (Dentascan), in assessment of the implant site in posterior maxilla & mandible. MATERIAL AND METHODS: data of total 11 patients with 20 implant sites were involved in the present study. Out of the 20 implant sites selected 10 were in posterior maxilla and 10 in posterior mandible. All the patients were routinely examined by panoramic radiography and CT. All images obtained i.e., conventional panoramic radiograph, and film based Dentascan MPR- CT images were evaluated for the detectability of mandibular canal at the mental foramen, 1 cm, 2 cm, and 3 cm posterior to mental foramen. The judgments were then compared by using the four point grading score. RESULTS: Both the statistical analysis and radiographic observation showed that Dentascan MPR CT gives significantly clearer images at the mental foramen and 1 cm, 2 cm , 3 cm posterior to it. Dentascan also provides significantly better visualization of the vital structures along with the bone density. The panoramic and Dentascan MPR CT images did not show a significant difference in visualization of the crest of alveolar ridge in both maxillary as well as the mandibular arch. CONCLUSION: The Dentascan MPR- CT images revealed significantly clearer images as well as better visualization of the vital structures than conventional panoramic radiography. Apart from providing clearer images Dentascan also gives the buccopalatal/buccolingual dimension at the implant site, along with the density of the available bone.
ABSTRACT
INTRODUCTION: Host response and environmental factors are known to modify periodontal status adversely. Presently serum, saliva, and GCF are being investigated for its biochemical constituents. GCF contains array of biochemical factors, offering potential use as a diagnostic or prognostic biomarker of the biologic state of the periodontium in health and disease. Alkaline phosphatase is produced locally in the periodontium and shows positive correlation with disease activity and PD. Present study was designed to analyze the levels of ALP in GCF and serum of patients with gingivitis, chronic & aggressive periodontitis before and after SRP & to compare the difference within the study groups. METHODS: OPD patients grouped into: Gingivitis, Aggressive periodontitis & chronic periodontitis patients. Clinical parameters recorded for each patient prior to therapy. Pooled GCF samples collected using micro capillary tubes from the deepest pocket sites for each patient and stored at -70° C. Serum samples also collected and stored at -20° C. Each patient was subjected to scaling and root planing with two weeks maintenance recall. After 6 to 8 weeks GCF and serum samples collected again and all clinical parameters rerecorded. GCF and serum samples analyzed for levels of ALP by using para nitro phenol assay for the three groups. RESULTS: ALP levels in GCF increased significantly during active phase of disease followed by statistically significant reduction after phase I therapy. Baseline levels of ALP in GCF was CP > AP > G with maximum reduction in GCF ALP after SRP in G > CP > AP group.
