Comparision between Conventional Radiography (IOPA) and Digital Radiography
Diagnosis is the
process of assessing a patient’s health as well as ensuing opinions formulated
by clinicians. Oral diagnosis is the art of using scientific knowledge to
determine the nature of oral diseases and distinguishing it from other diseases
.Radiography is a
well established procedure in daily dental practice and is still the most basic
and an important diagnostic tool available. Radiographs play an integral role
in the assessment of periodontal diseases. Conventional bitewing and intra oralperiapical radiographs are commonly used to detect alveolar bone loss
associated with periodontal disease. They provide unique information about the
status of the periodontium and a permanent record of the bone throughout the
course of the disease. However, the quality of an X-ray sensitive film can be
affected by multiple variables such as improper exposure, underor overdeveloping
and poor fixing.
Over the past few
years, systems that can generate radiographic digital images without the need
for radiography film have become available for use in clinical practice and are
gaining popularity among practitioners. Such digital radiography can also reduce
the radiation exposure. One of the most useful advantages of digital
radiography is the knack it provides to the clinicians to send images to
practitioners in a matter of minutes, for which it has become widely accepted
as an alternative to film-based radiography .A few studies
(most of which were performed in vitro) that examined the use of digital
radiography in evaluating crestal alveolar bone loss associated with
periodontal disease listed out few of its main advantages over conventional
radiography to be speed, convenience, lack of dark room procedures, image
improvement tools and dose reduction. Thus the implementation of digital
radiography in a dental practice seems to provide a solution for the future
imaging requirements.
