Background: Dental and cranio-maxillofacial diagnostic imaging constitutes an invaluable tool in the accurate diagnosis and management of a diverse range of conditions and diseases that afflict the oral and cranio-maxillofacial region. In order to improve on any existing facility, periodic audit evaluation is paramount. In this way proper and relevant service delivery can be achieved. Objective: To evaluate the range and volume of dental and cranio-maxillofacial diagnostic radiographic services offered at the University of Nairobi Dental Hospital (UNDH) in Kenya over a 5-year period (2006-2010). Methods: Retrospective survey involving manual examination of patient records at the Division of Dental and cranio-maxillo- facial Radiology registry of the UNDH. Results: Over the study period, the range of diagnostic radiographic services offered comprised of both intra- and extra- oral examinations. The total volume of radiographs taken was 48,874 among which 41,980 (86%) were intraoral and 6894 (14%) extraoral views. Among the intraoral views, 74% were bitewing, 25% periapical and only 1% were occlusal diagnostic views. The majority (95%) of the extraoral projections consisted of panoramic views and only 5% constituted other techniques. The volume of radiographs was high from January to September while November and December had the lowest number of examination requests. Conclusion: Intraoral radiography was the commonest examination with bitewings having been the majority while the panoramic tomography was the com- monest extraoral examination performed.
To study the Knowledge, Attitude, and Use of Pit and Fissure Sealants by Dentists in Nairobi. Materials and methods: This was a descriptive cross-sectional study which was done between May and June 1999. Questionnaires were distributed to 115 dentists who were sampled through convenience sampling. Setting: Nairobi Subjects: Dentists in public and private practice. Results: Sixty nine dentists (60%) responded. (50.7%) of the dentists had average knowledge on PFS. Majority of the respondents (92.7%) agreed that Pit and fissure sealants should be part of preventive measures for dental caries. (65%) claimed to use Pit and fissure sealants with only a third using them regularly. The Pediatric dentists used sealants frequently. Conclusion: Application of PFS was not practiced much in Nairobi and sealant usage was associated with dentist's knowledge about them. There is need to disseminate knowledge on PFS to the dentists and sensitize the public about prevention of dental decay using sealants.
