ABSTRACT
Objective:To investigate the curative effect of different restorations for deciduous teeth defect of children.Methods:67 children with teeth defecting seriously and being unable to fill restore were enrolled from January 2011 to January 2015 and randomly divided into three groups,one group of patients accepted metal crown restoration (Group A,n=22),one group adopted ceramic inlay restoration (Group B,n=22),and the last one accepted silver amalgam filling (Group C,n=23),the curative effect and incidence of adverse reactions among three groups in the period follow-up were compared.Results:In the period of 18-month follow-up,6 patients of toothache,5 patients of food impaction and crevices between restorations and teeth,3 cases of gingival congestion,2 cases of secondary caries were observed in group C;3 cases of toothache,1 case of food impaction,gingival congestion,crevices between restorations and teeth and secondary caries were observed in group B;2 cases of toothache and food impaction,1 case of gingival congestion were observed in group A.The incidence of adverse reactions in group A and group B was lower than those in group C (P＜0.05),which was lower in group A than that in group B,but no significant difference was found between group A and group B (P＞0.05).Conclusion:The restoration of metal crown and ceramic inlay deserved popularization had better curative effect and safety for deciduous teeth defect of children than silver amalgam filling.
ABSTRACT
Objective:To investigate the influence of chronic periodontitis on the clinic effect of implant restoration.Methods:Fifty-two cases of chronic periodontitis patients with 70 implants and forty-nine cases of periodontally healthy patients with 69 implants admitted into our hospital from July 2013 to June 2016 were named as observation group and control group respectively.The implants survival rates,marginal bone loss (MBL),modified plaque index (mPLI),modified sulcus bleeding index (mSBI),and peri-implant probing pocket depth (PD) as well as IL-1,IL-6 in peri-implant sulcular fluid of the two groups were detected and analyzed after loading of 1,3,6,12 months.Results:After 12 months of loading,no obvious difference was found in the implants survival rate between two groups (P＞0.05).After 1,3 months of loading,no remarkable change was found in mPLI,mSBI,PD,and MBL between two groups(P＞0.05),while mSBI,PD,and MBL in observation group were significantly higher than those of control group except of mPLI after 6 months of loading (P＜0.05).Additionally,after 1,3 months of loading,IL-β in control group was not detected,while IL-β in observation group was conspicuously higher than those of control group after 6 months of loading and IL-6 in observation group was significantly higher than that of control group after 3 months of loading (P＜0.05).Conclusion:Chronic periodontitis could decrease the clinical effect ofim-plant restoration,which was probably due to the occurrence ofperi-implantitis.
