Radiation dose as a factor in the choice of routine pre-operative dental radiographs.

Radiation doses received by patients during dental x-ray examinations were measured in 95 patients referred to the X-ray Department of the Teaching Dental Hospital, University of Nairobi. The mean skin dose for single periapical films was 5.96 milligray (596 millirads) with the bitewing view recording a mean dose of 5.57 milligray (mGy). During a 14-film full-mouth periapical survey, mean doses ranged from 10.3-16.2 mGy for the upper jaw and 10.1-13.5 mGy for the lower jaw, respectively, depending on the region of dentition. In these full-mouth examinations, the distribution of skin dose over different parts of the dentition showed a characteristic pattern which may be explained by the overlap of radiation fields in the aggregated series of exposure. Orthopantomography recorded lower mean skin doses of 3.26 mGy in the molar region and 2.67 mGy at the posterior midline at the level of the 2nd cervical vertebra. The relative merits of intra-oral radiography versus orthopantomography are discussed, with radiation dosage as one of the factors to be considered. Some observations are made on measures to reduce patient dose.

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.

Skeletal and dental fluorosis: two case reports.

Two case reports from a high fluoride (10 ppm) rural community. They presented with severe degrees of dental fluorosis, hyper-sensitivity of teeth and skeletal fluorosis all arising from the ingestion of high amount of fluoride in water over a long period of time. Both cases had deformities of the upper and lower limbs. However, the deformities were more pronounced in the lower limbs than in the upper limbs, resulting in knock knee. Radiological finding showed osteosclerosis of the axial bones while the appendicular bones exhibited osteoporosis. There was marked change of bone structure observed as osteomalacia, and course trabecular bone pattern. Osteoporosis was also associated with cortical thinning. Periosteal bone apposition was observed in the bones: and genu valgum of the limbs. Biochemical tests revealed normal values for serum calcium and inorganic phosphate. However, the serum alkaline phosphatase was elevated. This may be an indication of a pathological condition where there are possible compensatory mechanisms to maintain normal levels of serum calcium and inorganic phosphate. One case which had undergone corrective surgical intervention of the lower limbs four years earlier, had continued to live in the same environment using drinking water with 10 ppmF after corrective surgery, and showed no improvement.

Pediatric recurrent sialectasis: case report.

A 2 1/2-year-old female presented to the Department of Paediatrics with a fever (38.2 degrees C) and bilateral swelling of the parotid salivary glands. A month later, she presented with similar signs and symptoms. Three months later the patient had a third attack and was referred to the Paediatric Dental Department. A clinical examination and sialography showed a normal Stensen's duct. The parenchyma of the right parotid had a combination of punctate lesions (1-2 mm in diameter) and globular lesions (3 mm in diameter). In the left parotid there were punctate lesions approximately 1 mm in diameter. The patient was managed with antipyretics (acetaminophen) and penicillin. This condition should be referred to as sialadenitis pediatrica as it presents as a clinical entity with signs and symptoms of swelling and pyrexia in the absence of sialography and histological findings. It is referred to as sialectasis after histological and sialographic observations detect lesions affecting the parenchyma of the salivary glands.
