摘要

本研究的目的是利用细菌培养的方法评估31个牙髓坏死和根尖周病变的乳牙根管内细菌的流行情况。冠接触后，用吸水纸收集材料进行微生物学评价和菌落形成单位(CFU)测定。厌氧微生物占96.7%，黑色素杆菌占35.5%，好氧微生物占93.5%，链球菌占96.7%，变形链球菌占48.4%。结论:牙髓坏死和根尖周病变的乳牙根管感染为多微生物感染，微生物数量多，以链球菌和厌氧微生物为主。

Prevalence of microorganisms in root canals of human deciduous teeth with necrotic pulp and chronic periapical lesions.

The objective of this study was to evaluate bacterial prevalence in 31 root canals of human deciduous teeth with necrotic pulp and periapical lesions using bacterial culture. After crown access, the material was collected using absorbent paper points for microbiological evaluation and determination of colony forming units (CFU). Anaerobic microorganisms were found in 96.7% of the samples, black-pigmented bacilli in 35.5%, aerobic microorganisms in 93.5%, streptococci in 96.7%, and S. mutans in 48.4%. We concluded that in human deciduous teeth root canals with necrotic pulp and periapical lesions the infection is polymicrobial, with a large number of microorganisms and a predominance of streptococci and anaerobic microorganisms.
