A Comparative Study on the Efficacy between Minimally Invasive Caries Removal Technique involving Carisolv and Traditional Mechanical Caries Removal in Treating Dental Caries in Children

Objective:To explore the curative effect of Carisolv,a minimally invasive caries removal technique and traditional mechanical caries removal treatment on children’s dental caries.Methods:A total of 97 children with dental caries who were treated in the Department of Stomatology in Affiliated Hospital of Chifeng University,Chifeng from September 2017 to May 2019 were selected and recruited as the research subjects.They were divided into two groups by random number table method.Forty-nine individuals were assigned in the control group while the remaining 48 individuals in the observation group.The control group was treated with traditional mechanical caries removal method,and the observation group was treated with minimally invasive caries removal technique,i.e.Carisolv.Both groups were followed up for six months.The degree of pain,recovery time of dental function and complications after six months of treatment were observed in the two groups of children.Results:During the treatment,compared with the control group,the children in the observation group experienced lower degree of pain and had shorter recovery time of dental function.After six months of treatment,the incidence of complications in the observation group was lower than that in the control group.The difference was statistically significant(P<0.05).Conclusion:Compared with traditional mechanical caries removal method,Carisolv,a minimally invasive caries removal technique could reduce the pain of children during the treatment process,shorten the time to restore dental function,reduce the occurrence of complications,and had a better therapeutic effect in treating children’s dental caries.

INFLUENCES OF TWO CARIES REMOVAL METHODS ON BLOOD PRESSURE AND PULSE IN CHILDREN

Objective To compare the effect of chemomechanical caries removal （CMCR） to traditional drilling （TD） on blood pressure and pulse in children. Methods Of all 105 subjects, 53 were randomly assigned to CMCR group; 52, to TD group. For each subject, the systolic pressure （SP）, diastolic pressure （DP） and pulse （ P ） were measured at five time-point： pre-treatment, initiation of carious removal, the end of carious removal, the end of the cavity restoration, and the end of the dental care. They were recorded as To, T1 , T2, T3, and TE, respectively. The difference of SP, DP, and P within each group were analyzed. Results Of all 105 subjects, 14 were administered local anesthesia. Since local anesthesia may be a confounding factor for changes in blood pressure and pulse, only the data of the other 91 subjects that local anesthesia were not administered were analyzed. Regarding the SP, DP, and P for TD, the difference between TO and T1 was significant （ P = 0. 013, 0. 015, 0. 012 respectively）, while not significant between T1 and T2, T2 and T3, T3 and TE（ P 〉0. 05）. Regarding the SP, DP, and P for CMCR, the differences were not significant between every two consecutive time-points （ P 〉 0. 05）. The differences of the SP, DP, and P between CMCR and TD were not significant for time-points T0, T3 and Te （p 〉 0. 05 ）, while significant for T1 and T2 （ P 〈 0. 05 ）. Conclusion In general, CMCR induces less increase of blood pressure and pulse in children compared to traditional drilling （TD）. It may be inferred that CMCR is less distressing than TD.
