In this thesis, the use of radiography in endodontic practice and the importance of radiographic interpretation of periapical lesion, file and working length, and the second mesio-buccal canal (MB2) of maxillary first molar were studied. The aims of the questionnaire study were primarily to evaluate the opinions and attitudes of general dental practitioners (GDPs) and endodontists in the UK towards the use of radiography and radiographic equipments in endodontic practice. The second aim was to investigate the ability of endodontists and GDPs to interpret early apical pathology. The impact of viewing conditions on the interpretation of file and working length study was conducted to determine whether or not ideal viewing conditions have any influence on the diagnostic accuracy of observers. Finally, the effects of horizontal angulation on the interpretation of MB2 canal in maxillary first molar study was conducted in a comparison of three imaging modalities in terms of sensitivity and specificity to determine the optimal horizontal beam angulation and radiographic system for the detection of MB2 canal. Conclusions: Certain radiographic techniques highlighted by the National Endodontic Guidelines and the Faculty of General Dental Practitioners have been adopted by both specialists and GDPs in the UK. However, endodontists were more able than GDPs to recognise an early apical lesion. Furthermore, optimal viewing condition for endodontic working length requires the use of a viewing box, masking and magnification. Finally, a +20o horizontal beam angulation was found to be optimal in the identification of MB2 canal of maxillary first molar with all imaging modalities.
