Summary

Smoking significantly impacts oral microcirculation, altering capillary calibre and tortuosity. This study demonstrates video-capillaroscopy as a reliable, non-invasive method to assess these smoking-related changes in labial mucosa.

Area of Science:

  • Oral Medicine
  • Microcirculation Research
  • Vascular Biology

Background:

  • Smoking is a major risk factor for oral diseases.
  • Previous research has explored smoking's effects on microcirculation.
  • Non-invasive techniques like video-capillaroscopy offer new avenues for study.

Purpose of the Study:

  • To analyze labial microcirculation characteristics in vivo.
  • To evaluate the impact of smoking on oral microcirculation using computerized video-capillaroscopy.
  • To establish smoking as a risk factor affecting oral microcirculation.

Main Methods:

  • Utilized computerized video-capillaroscopy for non-invasive analysis.
  • Examined 35 healthy smokers and 35 healthy non-smokers.
  • Assessed capillary visibility, course, tortuosity, calibre, microhaemorrhages, and density per square millimetre in labial mucosa.

Main Results:

  • Smokers exhibited significantly smaller capillary calibre (P<.001) compared to non-smokers.
  • A higher number of detectable capillaries per square millimetre was observed in smokers (P<.001).
  • Significant correlation found between increased capillary tortuosity and smoking habit (P<.001).

Conclusions:

  • Computerized video-capillaroscopy provides a simple, reliable method for investigating labial microcirculation.
  • Smoking habit is a significant risk factor for oral diseases, demonstrably affecting oral microcirculation.
  • Findings underscore the detrimental effects of smoking on the vascular system of the oral mucosa.
