Methods: Recordings were made from upper central and lateral incisors as well as from surrounding gingiva in healthy volunteers (n=30) and type I diabetic patients (n=10) using a laser Doppler flowmeter (Periflux PF5001 masters; Perimed Jarfalla, Sweden).
Results: The average blood flow signal recorded from central incisors in healthy subjects was 12.92 ± 5.9 while in diabetic patients was 6.50±2.2 (p<0.05). Recorded blood flow from lateral incisors in healthy patients was 19.13 ±5.2 and in diabetic patients 10.24±3.1 (p<0.05). The blood flow signal obtained from gingiva surrounding incisors in healthy patients was 33.07±4.8 and in diabetic patients 13.28±1.1 (p<0.05).
Conclusions: The results suggest that in type I diabetic patients, blood flow through pulpal and gingival tissue was significantly reduced compared to healthy subjects.
