Abstract:
Objective To investigate the levels of hypoxia-inducible factor 1α(HIF-1α)and lipopolysaccha-ride signal receptor(CD14)in gingival crevicular fluid of preschool children with dental caries and their clini-cal significance.Methods A total of 468 preschool children(aged 3-6 years)who underwent oral examina-tions in the hospital from April 2022 to May 2024 were selected as the research objects and were divided into the observation group(with dental caries,n=107)and the healthy group(without dental caries,n=361)based on the presence or absence of dental caries.The observation group was further divided into three sub-groups according to the degree of caries activity test(CAT)score:low activity group(n=29),moderate activ-ity group(n=46),and high activity group(n=32).The children in the observation group were followed up for 6 months,and then divided into the occurrence group(n=36)and the non-occurrence group(n=71)based on whether chronic apical periodontitis occurred during the follow-up period.The levels of HIF-1α and CD14 in gingival crevicular fluid in the research objects were detected.The relationship between the levels of HIF-1α and CD14 in gingival crevicular fluid of preschool children with dental caries and CAT score was ex-plored by Pearson correlation analysis.The predictive value of HIF-1α and CD14 levels in gingival crevicular fluid for chronic apical periodontitis in preschool children with dental caries was explored by receiver operating characteristic(ROC)curve.Results The levels of HIF-1α and CD14 in gingival crevicular fluid in the obser-vation group were higher than those in the healthy group(P<0.05).With the increase of CAT score,the lev-els of HIF-1α and CD14 in gingival crevicular fluid gradually increased(high activity group>moderate activi-ty group>low activity group),and the differences were statistically significant(P<0.05).The levels of HIF-1α and CD14 in gingival crevicular fluid of preschool children with dental caries were positively correlated with CAT score(r=0.526,0.634,P<0.001).The levels of HIF-1α and CD14 in gingival crevicular fluid in the occurrence group were significantly higher than those in the non-occurrence group(P<0.05).ROC curve analysis showed that the area under the curve(AUC)of combined prediction of HIF-1α and CD14 levels in gingival crevicular fluid for chronic apical periodontitis in preschool children with dental caries was 0.902(95%CI:0.857-0.952),which was higher than 0.709(95%CI:0.664-0.759)and 0.825(95%CI:0.775-0.870)of individual prediction of HIF-1α and CD14 levels in gingival crevicular fluid.Conclusion HIF-1α and CD14 are highly expressed in gingival crevicular fluid of preschool children with dental caries,and their levels are related to the activity of dental caries and the occurrence of chronic apical periodontitis in preschool chil-dren with dental caries.The combined detection of the two can be used as effective indicators for predicting the occurrence of chronic apical periodontitis in preschool children with dental caries.
