Giant twin sialoliths presenting with acute cellulitis: a case report.

Sialolithiasis is a process of unknown aetiology in which calculus concretions form in the salivary gland ducts and tissue. It may occur at any age but it is most common in middle-aged adults. A case is presented of the occurrence of double giant sialoliths in the left Wharton's duct in a 16-year-old boy. The clinical symptoms and signs were somewhat atypical and included acute suppurative cellulitis in the floor of the mouth plus localized periodontitis involving 36. Under a local anaesthetic the stones were surgically extracted and healing was uneventful. Proper interpretation of symptoms and thoughtful investigation for localization of salivary stones is emphasized.

Oral health habits and periodontal health among a group of university students in Kenya.

The purpose of this study was to determine the oral health habits and periodontal health among a group of university students in Kenya. The study comprised 243 randomly selected first year students, mean age 23 years, at the University of Nairobi. Questionnaire response showed that 39% of the participants had visited a dentist before, mainly for extraction. Sixteen per cent said they visited a dentist at least once a year and 96% said they brushed daily. Clinical examination was done in a room with natural daylight using the WHO criteria. Plaque was visible on 35% of the surfaces. 11% of gingival sites examined bled on probing. Only one participant had pocket depth greater than or equal to 4 mm. Supra- and sub-gingival calculus was recorded at 18% of index tooth surfaces. The study will be considered as a baseline for later studies on oral health trends in similar populations.

Osteopetrosis presenting with paroxysmal trigeminal neuralgia. A case report.

Osteopetrosis is a rare disease of unknown aetiology. The relentless bone growth may progressively obliterate the various craniofacial skeletal foramina leading to nerve compression and a diversity of neurological disorders. A case is reported of a 37-year-old woman who was seen because of frequent attacks of paroxysmal trigeminal neuralgia (PTN); other orofacial neurologic deficits and generalised craniofacial skeletal thickening. The prompt recognition and management of associated disorders such as PTN is emphasized. Despite the lack of definitive treatment modalities for both osteopetrosis and PTN, the patient's quality of life must be sustained.

Ameloblastoma after surgical removal of an impacted mandibular molar. A case report.

A case of an ameloblastoma diagnosed about 3 1/2 years after removal of an impacted mandibular 3rd molar is presented. The pre-operative radiographs, though poor in quality, showed an ill-defined radiolucency in relation to the tooth. This feature was not apparent to the examiners at the time of first presentation. Despite unfavourable working conditions in developing countries, a high level of suspicion should be maintained to avoid serious sequelae at a later stage.

Pathogenesis of odontogenic cysts: an update.

This article briefly reviews the origin, classification and pathogenesis of the various odontogenic cysts. Keratocysts and follicular cysts are said to be developmental lesions arising from the remnants of the dental lamina and the cell rests of the dental follicle respectively. The radicular cysts are the most commonly occurring lesions associated with the apices of non-vital teeth. They are said to arise from proliferation of the cell rests of Malassez in chronically inflamed granulomata. It is noted that bone resorption is the major requirement for any bony lesion to expand; hence the interest in the role of diverse cellular and chemical mediators of bone resorption in disease. The current concepts of the role, in cyst initiation and growth, of enzymes including cellular metabolites and cytokines are presented. Evidence on the activities of collagenase, arachidonic acid metabolites, leukotrienes, hydroxyeicosatetraenoic acids, interleukin--1 and prostaglandins is cited. It is observed that the understanding of these cellular and molecular biological behaviour patterns may yield more appropriate information necessary for the development of more effective management modalities for such tissue degrading lesions as odontogenic cysts.

Fibrous dysplasia of the jaws: a case report.

This article reviews the present clinical, radiographic and histologic features of fibrous dysplastic lesions of the jaws. A case is presented of an apparently reactivated fibrous dysplastic jaw lesion, with evidence of cystic degeneration, in a 33-year-old female school-teacher who was first seen at the Department of Dental Surgery, University of Nairobi in March 1986. The dilemma in the management of fibrous dysplasia is reviewed and discussed. It is noted that while conservative surgical procedures remain the treatment of choice, situations arise where tremendous tissue activity would require early intervention by numerous cosmetic surgical shaving procedures. The present case, however, offers a unique management challenge due to the occurrence of extensive cystic degeneration in the mandible.

A conservative management of an extensive odontogenic residual cyst: a case report.

This article briefly reviews the clinical presentation and management of odontogenic cysts. A case is reported of an 18-year-old girl who, on 12-3-1986, presented for the first time at the Dental Department, University of Nairobi with a painful bony swelling in the chin area. The extensive swelling apparently arose long after the traditional removal of two mandibular incisors. After periodontal prophylaxis the cystic lesion was enucleated under a local anaesthetic and the cavity lining subjected to histopathological examination which revealed appearances consistent with those of an odontogenic residual cyst. Immediate wound care involved dressing the defect with zinc iodoform paste on ribbon gauze for 4 weeks when complete granulation and epithelialisation occurred. Subsequently the patient was instructed on homecare irrigation of the cavity without packing. Clinical and radiographic assessment showed progressively satisfactory healing of both the soft tissue and bone through a follow-up period of about two years. It is suggested that the cavity filling in process by periosteal and endosteal bone deposition may be faster where the defect is left without a pack or obturator following complete granulation and epithelialisation.

Clinical report on longitudinal post-eruptive changes in fluorotic enamel observed in 10 cases over a 2 1/2 year period.

The present longitudinal study was conducted on ten children from age 5-6 years to determine the post-eruptive enamel changes of fluorosed permanent incisors. The children were born and reared in an area of Kenya with a water fluoride level of 14-45 parts per million. The incisors were examined and photographed periodically from the time of eruption over a period of 2 1/2 years. It was noted that the fluorosed incisor was intact as it erupted and then it underwent a variety of changes. In some there was mechanical breakdown (pitting) of the chalky white enamel which occurred rapidly initially and then the breakdown slowed down by 2 years. In others, there was smoothening of the pitted enamel resulting in a translucent appearance. Alternatively there was some degree of patchy staining of the enamel without surface breakdown. Much of the cervical 1/3 of the enamel remained intact even in teeth with severe breakdown. In most cases, these changes were bilaterally symmetrical. The possible reasons for these changes are discussed.
