RESUMEN
The edentulous mandible provides a frequent indication for oral implants. In many cases implants are placed in the interforaminal region to support fixed prostheses or give retention to removable overdentures. One of the hazards of this seemingly safe surgical area is hemorrhage of the floor of the mouth. In this article, two cases of this life-threatening complication are reported.

Small bone defects due to atrophic, traumatic or periodontal bone loss can be grafted with autologous bone grafts taken from the maxillary tuberosity. This study presents a 1-3 years follow-up of 22 patients who were treated according to this technique. Thirty-two implants were placed 6 months after bone grafting. All implants were functioning well at the time of investigation.

Subacute necrotising sialadenitis (SANS) has recently been reported as a possible separate disease of the palatal salivary glands. Only 12 cases have been reported to our knowledge. We describe the clinical and histopathological findings of three new cases, and conclude that it is unlikely that SANS is a disease in its own right.

An important aspect of surgical diagnosis before implant placement is measurement of the width of the alveolar ridge. Besides the use of radiographic methods, alveolar crest width can be measured by ridge mapping. A ridge mapping technique using a specially designed caliper (Ultimapper) is presented. Results of a research investigation are presented, which suggest that the technique is reliable and easily performed.

As an incidental finding a firm nodule was palpated in the skin overlying the right angle of the mandible in a 78-year-old female. The radiograph showed a dense calcification. Histologically the lesion proved to be a pilomatrixoma. A brief review of the literature of the pilomatrixoma is presented. Finally, some comments are made about calcification in the paraoral region, especially in the lateral aspect of the neck.

BACKGROUND: The histologic classification of epithelial salivary gland tumors may present difficulties due to their great morphologic diversity. METHODS: In this study, 478 parotid gland tumors were reevaluated and reclassified according to the 1991 WHO histologic classification of salivary gland tumors. RESULTS: In 56 cases, the original diagnosis was changed, either within the benign or the malignant tumor group. In six cases (1.3%), the original diagnosis was changed from benign to malignant or vice versa. CONCLUSIONS: During the mean follow-up period of 10.3 years, no events occurred supporting or rejecting the proposed change in diagnosis in these six patients. With regard to the three cases in which an original malignant diagnosis was made, the possibility of an overdiagnosis, and therefore an overtreatment, remains.
