In this study we investigated the effect of treatment with risedronate on glucocorticoid -prednisolone- induced decreases in bone density, quality, strength and growth of the tibia and mandible in growing rats. Trabecular and cortical bone structure was measured by peripheral quantitative computed tomography (pQCT) and three-dimensional (3D) micro-computed tomography (micro-CT). Indicators of bone strength were calculated from cortical bone density and the modulus of sections obtained from pQCT analysis. Tibial and mandibular bone sizes were also measured. Prednisolone decreased the bone growth of both tibia and mandible. It also caused deterioration of trabecular and cortical bone structure and strength in the mandible, and in cortical bone in the tibia, but had no effect on trabecular bone in the tibia. Risedronate inhibited the prednisolone-induced decreases in tibial width and mandibular length and height but did not improve the retardation of longitudinal bone growth. Risedronate prevented prednisolone-induced deterioration of trabecular and cortical bone architecture. In the mandible, this protective effect of risedronate was accompanied by an increase in cortical bone density and in bone strength. These findings show that risedronate inhibits prednisolone-induced loss of bone density, structure, decrease in bone strength, and retardation of bone growth in the mandible in young growing rats.","PeriodicalId":23086,"journal":{"name":"The Journal of The Kyushu Dental Society","volume":"86 1","pages":"1-17"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84375614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study sought to determine the relative frequency of odontogenic tumours in the Japanese population and to compare these data with previous classifications of odontogenic tumours.289 patients with odontogenic tumours diagnosed at the Department of Oral Pathology in Kyushu Dental College, Japan during a 20-year period from 1985 to 2004 were reviewed and reclassified according to the revised histopathological classification of odontogenic tumours by WHO published in 2005. Clinical data, including frequency, age, gender, and anatomical location, were also analyzed and collected.Odontogenic tumours accounted for 4.1% of all the oral and maxillofacial lesions (n=289).Of these, 289 patients (99.31%) had benign tumours and 2 (0.69%) had malignant tumours. The most frequent of the benign tumours were keratocystic odontogenic tumours (n=86), followed by ameloblastomas (n=81) and odontomas (n=79).These tumours constituted 84.43% of the all the odontogenic tumours. The mean age for benign odontogenic tumours was 32.36 ±19.83 years and for malignant tumours was 30 years, with the majority 189 (65.40%) of odontogenic tumours occurring in the second and the third molar region of the mandible, especially the posterior region 139 (48.10%). The male:female ratio for the all odontogenic tumours was 1:0.91.Conclusions:Keratocystic odontogenic tumours therefore tend to show a higher frequency of occurrence among odontogenic tumours than ameloblastoma, according to this new classification.","PeriodicalId":23086,"journal":{"name":"The Journal of The Kyushu Dental Society","volume":"44 1","pages":"55-66"},"PeriodicalIF":0.0,"publicationDate":"2007-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81121777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
