Abstract

저자는 표준 촬영과 교익 촬영을 시행하여 치조골의 높이 측정, 인접면 치아우식증의 판
독, 비교 및 인접면 중첩에 대하여 조사한 결과 다음과 같은 결론을 얻었다.
1. 상악에서 P<0.05인 유의한 차이를 보이는 수치는 100%였고 하악에서는 94%로 나타났
으며 97%에서 교익촬영의 측정치가 표준촬영의 측정치 보다 크게 나타났다.
2. 표준 촬영의 시도시 해부학적 제한은 대부분 축소된 X-선상을 만들며 이는 경구개에
의해 더욱 증대 된다고 생각된다.
3. 교익 촬영과 표준촬영 사이에 유의한 차이가 존재하므로 촬영방법의 선택시 이점을 고
려하여야 한다
4. 표준 필름 및 교익 필름에서 수평 겹침은 상악제2대구치의 근심에 가장 많았고 하악
제2소구치의 원심에서 가장 적었으며 총 수평 겹침의 수효는 표준 필름의 경우 538개로 교
익 필름(372개)의 경우보다 더 많았다
5. 인접면 치아 우식증은 교익 필름에서 74개로 표준필름 (23개)에서 보다 더 많이 발견되
었고 인접면 치아우식증이 교익촬영에서 더 많이 발견된 것은 수평 겹층이 적고 촬영시 수
평각을 얻기가 쉬운 결과라고 생각된다.

The purpose of the present study was to investigate associations between periapical
and bitewing techniques by assessing the crestal alveolar bone.
This article also reports the ability of these two techniques to correctly detect
evidence of interproximal dental caries, and comparison between the interproximal
overlapping of teeth.
Bitewing and periapical radiographs were used from posterior quardants of 243 dental
students in Seoul National University.
The distance from cemento-enamel junction to the alveolar crest (CEJ-AC) was
measured for each proximal surface from the distal of cuspid to the distal of 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 reached for 100% and
in mandible, reached for 94%.
2. The anatomic 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.
3. Consequently, since the significant differences frequently exist between
measurements obtained from bitewing and periapical techniques, it is important to define
which technique is used.
4. The number of the interproximal overlapping was the largest medial side of the
maxillary second molar, while the smallest at the distal side of the mandibular second
premolar. And the overall number of the interproximal overlapping was more (538) in
the periapical technique than in the bitewing technique (312).
5. The interproximal dental carious lesions were detected more (74) on the bitewing
films than on the periapical ones (23).
The fact was resulted from the small number of interproximal overlapping and relative
easiness of obtaining horizontal angulation in taking the bitewing radiographs.
