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.展开更多

The aim of this study was to establish a possible correla-tion between removable partial denture in acrylic resin use after 5 years and dental diseases. Materials and Methods: Partially edentulous patients presenting for removable denture treatment at the Prosthodontics service of the Affiliated Hospital of Kinshasa University, Democratic Republic of Congo were assessed in this study. Patients were randomly assigned into 2 groups: Denture and non-denture group. Caries and periodontal diseases were compared between both groups. Statistical significance was set at p < 0.05. Results: The average age in the denture and non-denture-group was 53.15 (±SD 22.05) and 31.59 (±SD 11.98) years. Out of 160 teeth were decayed, both 110 teeth (68.75%) in the denture-group and 50 teeth (31.25%) in the non-denture group. The DMFT index calculated at start time of the study was 0.2 for both groups, after five years was 7.1 for the denture-group and 2.6 for the non-denture-group. The plaque index in the denture-group had an index of 1 and that of non-denture-group was 0.5. Conclusion: The relationship has been found between patients’ wearers a RPD and dental diseases.展开更多
