The microscopic examination of tissue from an ulcerated area of the gingiva in the right lower third molar region showed infiltration of the deeper tissues by aggregates of malignant squamous cells, the latter arranged concentrically around keratinized centers forming well-defined and prominent epithelial pearls. 1964-10-01T00:00:00Z /library/oar/handle/123456789/50784 Title: Methods for early diagnosis of oral tumors : cytology Authors: Camilleri, George E. Abstract: Notwithstanding the pioneer work of Beale (1860-61), Walshe (1843), Daniel and Babes (Babes, 1963) and Dudgeon (Bamforth, 1963), the development of exfoliative cytology as a diagnostic aid is attributed chiefly to Papanicolaou (Papanicolaou and Traut, 1941). His long careful studies established the reliability of exfoliative cytology and it is now used extensively in the early diagnosis of malignant and premalignant lesions of many sites in the body. Its role in the diagnosis of carcinoma of the oral cavity is being evaluated (J olley and Smith, 1965; Sandler, 1963) and its historical background has been reviewed by Haam (1965). Oral exfoliative cytology is applicable to various clinical conditions such as benign lesions that would not normally have been submitted to biopsy, lesions requiring repeated examinations, widespread lesions from which comprehensive sampling cannot be made by biopsy, persistent lesions after surgery or radiotherapy and in mass population screening. It also has a definite place in the diagnosis and management of many non- neoplastic diseases of the oral mucosa (Camilleri and Lange, 1966). 1968-12-01T00:00:00Z /library/oar/handle/123456789/44322 Title: Dental Association of Malta international conference, Malta '94 : 50th anniversary celebrations, 10-12th February 1994 : souvenir programme Abstract: This Programme for the Dental Association of Malta International Congress for 1994, held on the occasion of the 50th Anniversary of the Association contains details of the extensive Scientific Programme, the Trade Exhibition, the Social Events and Tours.

Abstract: OBJECTIVES: This study was undertaken to examine the prevalence of dental caries in Inuit (Eskimo) youth aged 5-22 years. METHODS: Both tooth-oriented indices and child-oriented caries patterns were recorded in a field study conducted in 1991 in Nain and Hopedale, Northern Labrador. Seventy-eight percent (N = 347) of all school-children in these two locations were examined by a single examiner. RESULTS: Three percent of the population were caries free and 88 percent of those with caries experience had untreated dental decay. The mean combined dmft and DMFT per child for all ages was 6.85, while the mean combined dmfs and DMFS was 15.72. About 38 percent of subjects had pit and fissure caries; 2 percent had hypoplastic lesions; 4 percent had faciolingual caries; 31 percent had molar-approximal caries and 22 percent had faciolingual and molar-approximal caries, the most destructive caries pattern. About 68 percent of the 5-6-year-olds and 26 percent of the 15-22-year-olds experienced the most destructive pattern of decay in their primary and permanent dentitions, respectively. CONCLUSIONS: Preventive measures should start well before the age of 5 years. Describing caries patterns according to the dentition type complemented the traditional indices. 1994-01-01T00:00:00Z
