Fig. 5. Comparison of the intravascular lumen area in each segment. In the oral mucosa, the intravascular lumen area for the DEX (+) effect site decreased significantly compared to that for the DEX (−) effect site (P < 0.001). Additionally, the intravascular lumen area in the periodontal ligament for the DEX (+) effect site decreased significantly compared to that for the DEX (−) effect site (P < 0.001). However, no significant differences were observed between the DEX (−) and DEX (+) sites in terms of the mandibular bone above and below the root apex and dental pulp. DEX, dexmedetomidine.
