A number of indices have been developed to assess
and quantify the quality of mandibular bone mass and to
observe the signs of resorption using panoramic images.
To evaluate the reliability of digital morphometric
indices-Panoramic mandibular index (PMI), Mental
index (MI)& Mandibular cortical index (MCI) in
detection of osteoporosis.
To investigate influence of age and gender for
To assess digital radio morphometric indices with
bone density in identifying risk group for
Materials & Methods:-
Retrospectively digital OPG images are collected
from archives of stored data from CS 8100 care stream
panoramic machine which are subjected to digital radio
morphometric measurements to assess the bone
mineralised density of mandibular bone. Samples are
divided as follows (years)
Group-1: 21-30 Years.
Group-2: 31-40 Years.
Group-3: 41-50 Years.
Group-4: 51-60 Years.
According to gender MI, MCI &according to age
PMI are significant in accessing risk of osteoporosis.
Statistical analysis revealed that females & old age group
subjects are more prone.
Our study concluded that millions of people
undergo OPG annually, so OPG is not only used for
dental problems but can also be used as screening tool to
prevent further complication of bone diseases. Well
trained dental practitioner can detect low mineral bone
density by simple screening analytical method, using
above panoramic indices.
