    Notes: Abstract Fifty-two patients who developed antro-oral fistula following tooth extraction were examined clinically and radiographically. Of these, 39 patients had only perforation of the antral floor and the other 13 had the tooth root pushed into the maxillary sinus. Maxillary sinusitis was present in 43 cases. The most frequent site of antro-oral fistula was the upper first molar, and the palatal root of the upper first molar was pushed into the antrum the most frequently. Our study suggested that most of the patients with antro-oral fistula had associated maxillary sinusitis before the extraction of the tooth. The highest risk of the occurrence of antro-oral fistula appeared to be at the time of extraction of the upper first molar associated with periapical and periodontal lesions.

    Notes: Abstract Oral radiographic findings often provide important clues that lead to early recognition and diagnosis of systemic diseases. The purpose of this study was to identify and analyze the oral radiographic manifestations of various systemic diseases. Conventional radiographs (panoramic, Waters' and dental radiographs) were evaluated in 68 patients with systemic diseases to assess abnormalities retrospectively. Furthermore, high-resolution CT and 3D-CT reformations were available in 2 cases. Various oral radiographic manifestations were present in 36 patients (52.9%): 22 patients with congenital, developmental and hereditary abnormalities; 7 patients with endocrine disturbance, a patient with blood disease and 6 patients with other diseases. The oral radiographic appearance of systemic diseases is considered to provide valuable information for the diagnosis and treatment planning of systemic diseases, especially with regard to abnormalities of the teeth and jaw bones. Furthermore, by using modalities such as CT, further detailed findings can be obtained.

    Notes: Abstract It is thought that the phase of inflammatory extension in osteomyelitis of the mandible varies according to the primary site of infection, that is, the causative tooth. This study was conducted to analyze the relationship between the extension phase of inflammatory bone changes and the causative tooth in patients with radiographically diagnosised osteomyelitis of the mandible. Between 1983 and 1993, a total of 219 patients with osteomyelitis of the mandible were seen in our department. In the age distribution, 135 cases occurred in men and 98 cases in women. Osteomyelitis was most prevalent in patients in their sixties (39 cases) followed by patients in their forties and fifties (38 cases each). The causative tooth was identified in 97 cases of osteomyelitis in the mandible. In the 39 cases in which the primary infection was caused by the third mandibular molar, distal extension was most prevalent (30 cases). In the 58 cases in which a tooth other than the third mandibular molar was the cause (front tooth, premolar, deciduous tooth and other molars), equal extension in the mesio-distal direction was most prevalent (40 cases). In the upper-lower extension phase, lower extension beyond the mandibular canal was most prevalent in the first, second and third molar teeth. In the cases involving teeth other than the mandibular molars, the inflammatory bone changes were rather limited to the upper part of the mandibular canal.
