A short-term analysis of the modification process of the plaque microbial community before and after treatment in children with S-ECC / 口腔疾病防治

Objective @# To explore from the perspective of microorganisms the changes in plaque microbial community of children with severe early childhood caries (S-ECC) before and 3 months after dental treatment. Meanwhile to show the effect of treatment on the maintenance of long- term caries-free state. @*Methods@# S-ECC children completed dental treatment under general anesthesia. We collected plaque from caries-free dental surfaces before treatment (caries, C) and at the postoperative follow-up review time points of 7 days (C-7D), 1 month (C-1 M), and 3 months (C-3 M). We included caries-free children (caries free, CF) as the control group to analyze the dynamic modification process of the plaque microbial community in the short-term pre- and postdental treatment.@*Results@#Species clustering analysis showed that the compositions of the microbial communities of the S-ECC and CF groups were highly similar. The α diversity index was not statistically significant (P>0.05). From the analysis of the relative abundance, Leptotrichia spp. and Aggregatibacter spp. decreased after treatment compared with before treatment (P<0.05). Streptococcus sanguinis in the C-7D group increased compared with that in the C group and gradually decreased within 3 months. Veillonella spp., Actinomyces spp., Allprevotella spp., Capnocytophaga spp., and Streptococcus mutans differed between the C and CF groups (P<0.05), Streptococcus mutans did not differ significantly between the C-7D and C-1 M groups and the CF group after treatment, while C-3 M showed an increase compared with the CF group (P<0.01). @*Conclusion@#The rapid change in the structure of the flora of children with S-ECC after treatment. The plaque microbial community structure in a caries-free state gradually starts to be established 1-3 months after treatment. There is a "core microbiota" in the oral plaque community that jointly maintains microecological stability. Veillonella spp., Allprevotella spp. and Streptococcus mutans have potential as possible microbial markers.

Evaluation of therapeutic effect and health economics of general anesthesia and routine outpatient dental treatment in children with severe early child caries / 华西口腔医学杂志

OBJECTIVES@#To evaluate the efficacy and health economics of the comprehensive therapy for the children with severe early child caries (S-ECC) under dental general anesthesia (DGA) and conventional outpatient treatment to provide references for dentists and parents in the choice of clinical treatment.@*METHODS@#A retrospective cohort study was conducted on S-ECC children aged 36-71 months and who received dental treatment under general anesthesia or routine outpatient situation. The filled tooth survival rate, treatment cost, and cost-filled tooth survival time of the two groups were compared, and the curative effect and health economics was evaluated.@*RESULTS@#The filled tooth survival rate of the DGA group was higher than that of the routine outpatient group (@*CONCLUSIONS@#Compared with the conventional outpatient treatment group, the treatment outcomes of S-ECC under general anesthesia were better, and the costs were higher. However, no significant difference was observed in the total medical cost-filled tooth survival time between these two groups, and the conventional outpatient treatment did not have evident economic advantages.

Investigation of postoperative complications in children after dental therapy under general anesthesia / 华西口腔医学杂志

OBJECTIVE@#This study aimed to evaluate the postoperative complications undergoing dental general anesthesia in children and analyze the prevalence and related factors.@*METHODS@#This prospective study involved 292 systematically healthy children (36 to 71 months old) who received extensive dental treatment under general anesthesia. Data about patients' histories, characteristics, dental and anesthesia procedure were collected. Parents or caregivers were interviewed face to face preoperation and 72 h postoperation. Data were analyzed using logistic regression.@*RESULTS@#Approximately 93.5% of the enrolled children reported one or more complications. The most prevalent complication was postoperative pain, followed by weariness, agitation, problem in eating, drowsiness, oral bleeding, cough, fever, etc. The length of operative time and femininity were the risks of the postoperative pain. Nutrition status was the factor probably in association with fever.@*CONCLUSIONS@#The children receive longer operative time and girls show to be more susceptible to the postoperative pain. High nutrition status could be the protective factor of postoperative fever.

Summary of nursing disable and mental retarded children with dental treatment under dental general anesthesia / 中国实用护理杂志

Objective@#This is a retrospective study of nursing 99 disable and mental retarded children with dental treatment under dental general anesthesia (DGA). This study may show a reference to nursing this kind of patients.@*Methods@#We choose the patients in our hospital from July 2017 to July 2018. And start the special nursing for disable and mental retarded children with dental treatment under dental general anesthesia.@*Results@#99 cases of children with disabilities can successfully complete all oral treatment. Among them, children with social disorders account for the majority of the visiting population; among disabled children, the incidence of caries, pulpitis and periapical periodontitis was increased.@*Conclusions@#Our nursing work should be done individually for this kind of children, improve the children obedience and can ensure the treatment smoothly and successfully, reduce the pain through the treatment and improve the recovery. It will give a theoretical and practical reference of nursing this kind of children for dental treatment.
