Bitewing and periapical radiographic techniques are used in clinical and epidemiological
studies to assess crestal alveolar bone levels. The purpose of the present study
investigated relationships between these techniques by assessing alveolar crest location
at the same site. Bitewing and periapical radiographs were available from posterior
quadrants of 120 subjects. The distance from cemento-enamel junction to the alveolar
crest (CEJ-CR) was measured for each proximal surface from the distal of the cuspid to
the distal of the second molar. Data were arranged according to the proximal surface
examined, and bitewing and periapical measurements were compared using paired t
tests. The obtained results were as follows ;
1. In maxilla, a significant t ratio with a P value of 0.05 or less was reached for 78%
and in mandible reached for 39%.
2. Pearson correlations were calculated 32 surfaces (89%) had values below 0.70 and
so, data obtained by these techniques can not be used interchangeably on an individual
or group basis.
3. In situations where the periapical measure was greater than the bitewing, it ranged
up to 20.7% greater with a mean 9.8%. Where the bitewing was greater than periapical,
it ranged up to 51.9% greater, with a mean 18.2%.
4. The percentage difference was greater in maxillary posterior areas than in
mandibular molar, premolar areas. A lower prevalence of significant differences was
attributed to relatively more simply root and favorable radiographic conditions in
mandibular molar and premolar areas.
5. The anatomical limitations imposed on periapical radiographic technique, most often
result in somewhat foreshortened radiographic images. This situation would tend to be
accentuated by the anatomical restrictions of the hard palate.
6. Consequently, since the significant differences frequently exist between
measurements obtained from bitewing and periapical techniques, it is important to define
which technique is used.
