The aim of this study was to investigate how the thickness of the masseter muscle relates to the maxillofacial morphology, including the thickness of alveolar process in the mandibular incisor region, and the thickness of the mandibular symphysis. The subjects consisted of 80 adult male volunteers (mean age: 23 years 8 months). The relationship between masseter muscle thickness and the maxillof...

Three new species of non-marine ostracods, Strandesia martensi n. sp., Strandesia pholpunthini n. sp. and Oncocypris rostrata n. sp., are here described from the Northeastern part of Thailand. Strandesia martensi n. sp. is similar to Strandesia perakensis Victor & Fernando, 1981 and to Strandesia sanoamuangae Savatenalinton & Martens, 2010. It can be distinguished from these two species by the ...

The term odontogenic keratocyst was first used by Philipsen in the year 1956. The lesion was renamed by him as keratocystic odontogenic tumor (KCOT) and reclassified as odontogenic neoplasm in the World Health Organization's 2005 edition that occurs commonly in the jaws having a predilection for the angle and ascending ramus of mandible. In contrast, KCOTs arising in the maxillary premolar regi...

lntraosseous hemangiomas are benign tumors occurring most often in the skull and vertebrae. Rarely , these lesions can present in the maxilla and mandible. We found in the literature a case of an intraosseous hemangioma involving the mandibular condyle (1 ). We wish to report the panoramic zonographic, computed tomographic, and pathologic findings of another case involving both the condyle and ...

Proliferative periostitis is a rare form of osteomyelitis that is characterized by new bone formation with periosteal reaction common causes of proliferative periostitis are dental caries, periodontitis, cysts, and trauma. While proliferative periostitis typically presents as a localized lesion, in this study, we describe an extensive form of proliferative periostitis involving the whole mandib...

OBJECTIVES To study and document the mandibular angle of Nigerians from the north eastern arid zone, and investigate its role as an anthropological parameter for racial and or population groups differential diagnosis, its utilization in laryngoscopy and for successful inferior alveolar nerve anesthesia. DESIGN A cross sectional study. SETTING Department of Anatomy, College of Medical Scienc...

A sample of 41 dentulous dry mandibles from adult domestic pigs were studied in order to compare both the right and left sides according to age. Samples were grouped according to dental status: “subadults” (erupting third molar, n=19) and “adults” (fully erupted third molar, n=22). Individual levels of asymmetry were analysed from the xand y-coordinates of 16 landmarks on the dorsal aspect of t...

The ameloblastic carcinoma is a rare malignant counterpart of the ameloblastoma. Ameloblastic carcinoma is a malignant lesion with characteristic histologic features and behavior that dictates a more aggressive surgical approach than that of a simple ameloblastoma. However, reliable evidence of its biologic activity is currently unavailable due to the scarcity of well-documented cases. We prese...

The aim of the present investigation was to provide information about the long-term effects and optimal timing for class-II treatment with the Bionator appliance. Lateral cephalograms of 23 class-II patients treated with the Bionator were analyzed at three time periods: T1, start of treatment; T2, end of Bionator therapy; and T3, long-term observation (after completion of growth). T3 includes a...

INTRODUCTION The purpose of this investigation was to evaluate the dentoalveolar and skeletal cephalometric changes produced by headgear (HG) biteplane and bionator appliances in subjects with Class II Division 1 malocclusion. METHODS The sample comprised 60 patients with Class II Division 1 malocclusion; 30 (15 boys, 15 girls; mean age, 10.02 years) were treated with the HG biteplane for a m...
