Alveolar Vascularization, Relationship With Periodontal Commitment And Mobility: Pilot Study.
Objectives: To describe the vascularization of alveolar bone immediately after dental extraction, by quantitative and area analysis of alveolar vascular channels and unmineralized spaces, and associate them with periodontal compromise and dental mobility, after minimally invasive exodontia and support immersion endoscopy of the alveolus.
Methods: Ten patients (4 men/6 women) with 10 uniradicular teeth with exodontia indication, were included. They were categorized into 2 groups according to their periodontal commitment and mobility; as periodontally compromised (CAL>7mm, PD>5mm) or periodontally healthy (CAL<7mm, PD<5mm), and mobility (>1mm horizontally or vertically) or non-mobility (<1mm horizontally or vertically). The minimally invasive extractions were performed with BenexII® extractor and immediately afterwards, an immersion endoscope was introduced, with which an alveoscopy video was recorded. The images obtained were later analyzed with the software ImageJ for quantification of channels and unmineralized spaces by field. The number of vascular channels, percentage of vascular channels area (Vc) and percentage of unmineralized spaces area (UnB), between periodontally compromised and periodontally healthy, and those with mobility and non-mobility, were quantified and compared. Statistical analysis was performed using independent t-test (p-value<0.05).
Results: Compared with the group of non-mobility, the group mobility did not show significant differences in UnB, nor in Vc. In the periodontally committed group, significantly greater values of UnB were observed (33.451%) than in the periodontally healthy (19.654%) (p<0.05), but there were no differences in the variable of Vc.
Conclusions: The clinical relevance of this study was the new and useful research protocol that allowed us to perform an in vivo morphogenetic exploration at a microscopic level of the alveolar bone. The same protocol could be applied in several in vivo studies at a microscopic level to observe and quantify the architecture of other surfaces. Periodontal involvement could be associated with a higher area of unmineralized spaces. Increasing the sample size for this study could lead to greater conclusions.
