Objectives: This study evaluated the effect of adjacent gingival blood flow on detection of pulpal blood flow (PBF) using ultrasound Doppler flowmetry (UDF) through animal study. Materials and Methods: The study included 36 right and left maxillary the third incisors and canines in 9 experimental dogs. The study included 2 main steps: In the first step, the pulse sound level (PSL) was recorded on the cervical part of each tooth without flap elevation (Group 1), with flap elevation (Group 2), and after it was repositioned in place (Group 3). In the second step, the PSL was recorded on the cervical part of each tooth (Group 4), after pulpotomy (Group 5), after partial pulp extirpation (Group 6), after complete extirpation (Group 7), and after canal filling (Group 8). In Groups 5-8, the study was performed with and without flap elevation in the left and right teeth, respectively. The PSL was graded as follows: 0, inaudible; 1, heard faintly; and 2, heard well. The difference between each group was analyzed using Friedman's test with Wilcoxon signed-rank tests (α = 0.05). Results: In step 1, the PSL results were Group 1 > 2 and 3. In step 2, there was no significant difference between the groups when the flap was not elevated, while PSL results were Group 4 > 5 ≥ 6 and 7 ≥ 8 when the flap was elevated. Conclusions: PBF is affected by gingival blood flow when measured with UDF. UDF measurements require isolation of gingiva from the tooth.

본 연구는 온열요법이 표층부 혈류량과 피부 온도에 미치는 영향을 평가하기 위해, 건강한 성인 20명(남성: 10명, 여성: 10명)을 대상으로 습열요법과 초음파요법 적용전후의 전이부 표층부 혈류량과 피부 온도를 각각 laser doppler flowmetry와 접촉식온도계를 사용하여 측정함으로써 다음과 같은 결론을 얻었다. 1. 습열요법과 초음파요법 모두에서, 표층부 혈류량과 피부 온도는 적용전보다 적용후에 유의하게 증가하였다. 2. 습열요법을 시행한 경우, 초음파요법에 비해 적용직후 표층부 혈류량과 피부 온도의 증가량이 유의하게 더 컸으며, 증가된 상태도 더 오래 유지되었다. 3. 온열요법 적용전 표층부 혈류량과 피부 온도는 남성이 여성에 비해 더 높았다. 4. 온열요법 적용전후 표층부 혈류량과 피부 온도의 변화량은 남녀간의 유의한 차이가 없었다.
