a comparison of the accurate diagnosis of the horizontal & vertical bitewing images

Conditions: Periodontal Diseases; Dental Caries

Summary: the aims of this research are to determine if vertical bitewings will be more effective and more comprehensive for the diagnosis of caries and the level of alveolar bone loss than the horizontal bitewing technique for the patients at king abdulaziz university over the age of 18. this is a cross sectional study. all the images in this study will be conducted at school of dentistry, king abdulaziz university. each patients will be exposed to 4 horizontal bitewing for posterior teeth ( standard of care ) and 4 vertical bitewing for the same area ( experimental ). the radiographs will be processed digitally. all the x ray will be taken using the standard protection protocol.
