A three-year programme in oral diagnosis and treatment planning. A model using an interdisciplinary teaching team.

Diagnosis and treatment planning are considered to be the basis for successful clinical dentistry, however, these skills are difficult to teach and evaluate. At the Department of Diagnosis and Treatment Planning, Tel Aviv University Dental School, a 3-year teaching programme has been developed. The goals of the programme are to teach a systematic pattern of data collection from history, clinical examination, imaging modalities and models, and to use this data to identify the patient's problems and to arrive at a final diagnosis, to develop a treatment plan, taking into account all relevant information, and to consult experts when needed, to train in case presentation, and to deal with peer response. The program includes 20 h of lectures and 30 h of exercises in the 4th year, developing at least 8 full treatment plans per student in the fifth year, a 1 30-min weekly panel seminar during the final year, and a final integrative examination at the end of the 6th year.

Metastatic tumors to the jawbones: analysis of 390 cases.

A review of the English language literature revealed 390 well-documented cases of metastatic lesions to the jawbones. Most metastatic lesions were diagnosed in patients in their fifth to seventh decade. The primary site differed between the genders: for women, it was the breast followed by the adrenal, colo-rectum, female genital organs and thyroid; for men, it was the lung, followed by the prostate, kidney, bone and adrenal. The most common location of the metastatic tumors was the mandible, with the molar area the most frequent site involved. In about 30% of cases the oral lesion was the first sign of the malignant disease. The present data are compared with those of metastatic tumors to the oral mucosa and a view on the possible pathogenesis is presented.

Metastatic tumors to postextraction sites.

Review of the literature revealed 55 cases where tooth extraction preceded the discovery of metastases. The lung and breast were the most common sources of the metastasis, and the mandibular premolar area was the most common site. A soft tissue mass extruding from a recent extraction wound, and accompanied by pain, were the main symptoms in most patients. The mean time from discovery of the metastasis to death was 3.8 months. Tooth extraction appears to serve as a promoting factor in the metastatic process. A case of metastatic transitional cell carcinoma of the urinary bladder involving the area of a recently extracted mandibular third molar is reported.

Metastases to the oral mucosa: analysis of 157 cases.

A review of the English-language literature revealed 157 well-documented cases of metastatic lesions to the oral mucosa. Most (64%) were diagnosed in patients in their fifth to seventh decade. The frequency of the primary site differed between genders: for men it was the lung (35.5%) followed by the kidney (16%) and skin (15%); for women it was the breast (24%) followed by the genital organs (17%). The most common oral site was the gingiva and alveolar mucosa (54.8%) followed by the tongue (27.4%), and with much less frequency by the tonsil, palate, lip, buccal mucosa and floor of the mouth. Of the dentulous patients, 79% exhibited the metastatic tumor in the attached gingiva. The clinical appearance of the metastatic oral lesion in most cases resembled hyperplastic or reactive lesions.
