[Study on using laser Doppler flowmetry to determine the pulpal blood flow of immature maxillary incisors].

Objective: This study aimed to evaluate the influence of age on the pulpal blood flow (PBF) of immature maxillary incisors of maxillary incisors, which was detected by laser Doppler flowmetry (LDF).

Methods: LDF was used to detect the PBF value of maxillary central and lateral incisors of a child group (aged 7-13 years old) and a positive control group (aged 18-25 years old), as well as the central incisor of a negative control group (the central incisor had undergone endodontic treatment). We then compared the features of PBF in all groups with the influence of gender and position on PBF.
