POSSIBLE ROLE OF CRY1 AND CRY2 IN ORAL CARCINOGENESIS
Aim. Dysfunction of the circadian clock is involved in tumorigenesis, and altered expression of some clock genes has been found in cancer patients. It has been shown recently that the occurrence, development, prognosis, and treatment of cancer are closely related to the abnormal expression of certain circadian-clock genes. CRY1 and CRY2 circadian-clock gene plays an important role in the regulation of many normal hysiological rhythms. This proteins act as light-independent inhibitors of CLOCK-BMAL1 components of the circadian clock. It has been revealed recently that abnormal expression of CRY1 and CRY2 correlate closely with the occurrence and development of many cancers. However, the expr…

Influence of operator’s experience on the shaping and centering ability of WaveOne single-file system
Aim. The aim of this study was to assess the influence of operator experience on the centering ability of WaveOne reciprocating system on S-shape simulated root canals. Methods. Forty S-shaped canals in resin blocks were assigned in two groups (n=20 for each group). Groups 1 was shaped by an expert operator, postgraduate in endodontics with more of ten years experience, while a not expert operator, a student in the last year of study, with poor endodontic experience performed shaping in Groups 2. A first survey of canals has been made with K-file 10 to assess the working length (WL), after that the glide path was achieved with PathFile 1, 2, and 3 (Dentsply Maillefer) at the WL. Subsequentl…
A review of 50 cases of ameloblastoma in Nigerians.
Objectives. The purpose of this study was the review of 50 ameloblastoma in Nigerian patients observed in the Hos- pital of Ibadan. Ameloblastoma represents nearly 1% of all neoplasm located in the oral cavity. In 80% of cases it could be found in the mandible: 70% of these involving the molar region or the ascending ramus, 20% the premolar region and 10% the anterior part. Ameloblastoma is considered a benign neoplasm with slow growing-pattern and lo- cally aggressive behaviour. Methods. We collected the clinicopathologic data of 50 ameloblastoma from the files of the Hospital of Ibadan. Results. The 50 ameloblastoma occurred in patients from 8 years to 64 years, 25 cases (50%) were in the…
