The author has examined the abnormalities in panoramic radiographs of 668
edentulous patients. The distribution, type, incidence, and location of all abnormalities
were analized, and the distances between alveolar crest and anatomical structures were
measures. maxillary measurements were performed between alveolar crest and lower
margin of the maxillary sinus and mandibular measurements between alveolar crest and
upper edge of the mental foramen
The obtained results were as follows:
1. Of the 668 panoramic radiogaphs examined, 103(15.4%)showed one or more
abnormalities.
2. The incidence of abnormalities was decreased by years, which was 22.0% in 1970's
and 16.8% in 1980's and 12.1% in 1990's.
3. The distribution of abnormalities as follows:
43(40.2%) superficial root fragmental 24(22.4%) impacted teeth, 9(8.4%) imbedded root
fragments, 7(6.5%) cysts,7(6.5%) Eactures,5(4.7%) foreign bodies,5(4.7%) abnormal
radiolucencies,4(3.7% ) abnormal radiopacities, 2(1.9%) bony defects, 1(0.9%) tumor.
4. In the location of abnormalities,42 cases(35.3%) were in the maxillary posterior
region,26 cases(21.8%) were in the maxillary anterior region, 20 cases(24.4%) were in
the mandibular posterior region and 18 cases(15.1%) were in the mandibular anterior
region.
5. In the distance between alveolar crest and maxillary sinus, 109 cases(9.7%) were
below 0.5§®, 757 cases(67.6%) were between 0.5§® and 10§®, 254 cases(22.7%) were
above 10§®. In the distance between alveolar crest and mental foramen, 73 cases(8.8%)
were below 0.5§®, 501 cases(60.7%) were between 0.5§® and 10§® and 252 cases(30.5%)
were above 100§®.
