Abstract:
Objective: To study the clinical reference pulpal blood flow(PBF) values detected by laser doppler flowmetry(LDF) in healthy young population and to analyze their possible affected factors. Methods: Undergraduate students at the age of 17-23 years were enrolled. PBF of 12-22 were detected by LDF based on the standard procedure. Difference of the test results between different sex was analyzed by T test and variance homogeneity test, and the correlation with age was analyzed by the chi-square test, and the difference between the different teeth was analyzed by the random group analysis. Results: 400 students(250 males and 150 females with the average age of 19. 83 years) met the inclusion criteria. The clinical reference values of PBF of different anterior teeth were obtained by the detection of LDF. For the same tooth, PBF values of females were higher than that of males (P＜ 0. 05). PBF values of different ages shared no statistical significance(P＞ 0. 05). For the same gender, PBF values of middle incisor were higher than that of lateral incisors(P＜ 0. 05). Conclusion: The determination of the clinical reference values of PBF detected by LDF may promote the clinical use of this technology.
