    Views and preferences of patients attending a tertiary hospital in Nigeria on use of saliva for clinical or laboratory tests
    (2018) Lasisi, T.J.; Lawal, F.B.
    The purpose of this study was to assess the knowledge and views of patients on the use of saliva for clinical or laboratory analysis. This was a cross sectional survey of 189 patients attending one primary and one tertiary oral health facility in Nigeria. Information was obtained from participants using pretested structured questionnaires and SPSS version 23 to analyze the data. Tests of associations between variables were determined using Chi-square and level of significance set at < 5%. One hundred and fifty-two (80.4%) respondents were aware of the use of saliva for clinical or laboratory test. The majority 152 (80.4%) agreed that saliva is easier to collect than other body fluids while 63 (33.3%) preferred to give saliva sample to blood 54 (28.6%) and urine 51 (27%) for clinical or laboratory tests. Only 20 (10.6%) had given saliva for tests before. Ninety-nine (52.4%) indicated strong interest in donating saliva for research while only 4 (2.1%) had given saliva as samples for research work before. Age, educational status and occupational class were significantly associated with awareness of use of saliva as investigative specimen (p < 0.05). This survey revealed that majority of the patients were aware of the use of saliva as well as its advantages over other body fluids for clinical or laboratory tests. Very few indicated previous saliva sampling for clinical and laboratory tests. Thus there is need for development of precise, cheap and accessible saliva tests for patient-centered diagnostic testing and disease monitoring

    A comparison of clinical and radiographic caries diagnosis on posterior teeth of children seen at a Nigerian Teaching Hospital.
    (2010) Popoola, B.O.; Denloye, O.O.; Ajayi, D.M.; Sote, E.O.
    caries is the most effective means of ensuring resolution of the condition and its sequelae. The aim of this study was to compare the effectiveness of clinical and radiographic (using bitewing radiograph) methods of caries diagnosis in children. The subjects were 172 children within the age range of 5-12 years attending the Paedodontic Clinic of the University College Hospital for the first time. They were clinically examined for the presence of dental caries using the WHO criteria. Left and right bitewing radiographs were taken following the clinical examination to detect dental caries. Clinical examination found additional 4 occlusal caries (incipient caries) that were not diagnosed radiographically and radiographic examination revealed additional 20 approximal surface caries that were not evident clinically in deciduous teeth. In permanent teeth, 3 additional occlusal caries were diagnosed clinically while only one additional approximal caries was diagnosed radiographically. These observations revealed the additional diagnostic value of bitewing radiograph in the diagnosis of approximal caries in children and the importance of clinical examinations in diagnosis of early occlusal caries (incipient caries) which are difficult to see on dental radiographs. In view of these findings, the use of bitewing radiographs combined with careful clinical examination will be of great advantage in early detection of caries in children
