Digitalization in Dental Prosthesis and Comparative Analysis of IOPA and RVG techniques for Tooth Measurements

The tooth height is mostly measured during root canal procedure. It is the most common reason for taking intra oral radiography during any procedure performance. Dental radiograph is also captured to find underlying cause of dental problems like peri-apical lesions, carries, bone defects, post procedure assessment of surgery or procedure done by dentist, etc. Intra oral radiograph also helps in gathering essential information of morphological bone status that helps to determine prognosis of treatment. Dental radiographs help in selecting the treatment plan, and determining the outcomes of different therapies. The study was aimed at evaluating the parametric measurements as got through radiovisiography (RVG) and conventional (intraoral periapical [IOPA] radiographs) for the determination of height of tooth, crownlength, root length, mesiodistal diameter at crown and mesio-distal diameter at tooth root. Radiographs of12 subjects (healthy patients) were taken by conventional methods as well as digital method, 5 standard points were selected on each tooth and dimensions of 3 tooth of each subjects were recorded in mm. Total 180 sites were recorded and result was compared with previous studies done on dogs and other animals. The results didn’t show any significant statistical parametric variations in measured values between conventional and digital radiographic methods. Hence, both IOPA radiograph as well as RVG can be used, but RVG provides good images with lots of colour changes in software in lesser time with good storage facility in computers as compared to conventional methods.
