ABSTRACT
Objective:To investigate the effect of Vitapex paste in the root canal for deciduous teeth with chronic apical periodontitis.Methods:200 children with chronic apical periodontitis were selected and divided into two groups.The observation group (108 cases)was given Vitapex paste.The control group (92 cases) was given Zinc oxide iodoform paste.The effect of Vitapex paste in root canal for deciduous teeth with chronic apical periodontitis was evaluated by filling quality after 1 month'treatment,the VAS scores before and after treatment,long-term curative effect were compared between two groups.Results:After 1 month'treatment,the suitable filling rate of observation group was higher than that of the control group(P＜0.05).There was no statistical significance in the VAS scores between two groups (P＞0.05).After 1 week'and 1 month'treatment,the pain feeling were alleviated in two groups and significantly lighter in the observation group(P＜0.05).After 6 months' follow-up,the success rate was 96.3％ in the observation group and 87.0％ in the control group,the success rate of observation group was higher than that of the control group (P＜0.05).Conclusion:The filling process of Vitapex paste was simple and easy,which had a good therapeutic effect on chronic apical periodontitis of deciduous teeth and could relieve the toothache of patients.
ABSTRACT
Objective To observe the clinical curative effect of the joint application of Vitapex paste and AH plus,which cured the combined periodontic -endodontic lesion .Methods 72 patients of 113 teeth with the com-bined periodontic-endodontic lesion were chosen ,which were randomly divided into the two groups ,with all complete periodontal initial therapy and routine root canal preparation and dressing at the same time .The observation group included 36 cases of 58 teeth,when the first time to see a doctor ,injected Vitapex paste to the periapical tissue and periodontal tissue sparse area for 1 -2weeks.The sceond time,the tap root canal was closely filled withc AH plus paste and gutta-percha.The control group concludes 36 cases of 55 teeth,with the traditional method,the tap root canal was filled with AH plus paste and gutta -percha directly .Then observation of postoperative emergency response within 1 week,of periodontal clinical indicators (including the PD,BOP,PLI) in 1 month,3 months,6 months after periodontal initial therapy ,and of the long-term curative effect after 1 year.Results 1 week after root canal filling , there were 48 cases no reaction , 9 cases mild reaction and 1 case severe reaction in the observation group , while 47cases no reaction ,7 cases mild reaction and 1 case severe reaction in the control group .There was no statistical difference of evaluation of emergency response between the two groups (χ2 =0.002,P>0.05).Compared with the situations before treatment ,PD,BOP and PLI were all reduced significantly in 1,3 and 6 months after periodontal ther-apy (P0.05),while 1 month (t=2.581,5.984,1.870,all P<0.05),3 months (t=4.806,7.640,1.034,all P<0.05) and 6 months (t=4.612,8.043,1.167,all P<0.05) later,there was statistical difference of decreased value between the two groups .The 1 year follow up showed that significant efficiency in the observation group was 46.55%,and total efficiency was 91.38%,while significant efficiency 27.27% and total effi-ciency 70.91%in the control group ,and there were statistical differences of significant efficiency and total efficiency between the two groups (χ2 =16.761,21.061,all P<0.05).Conclusion With the joint application of Vitapex paste and AH plus ,and two method curing the combined periodontic -endodontic lesion ,there was no evident differ-ence compared with the traditional short -term emergency response .By long-term observation ,found that this method could effectively promote the healing of periapical tissue and periodontal tissue ,and that curative effect is remarkable compared with the traditional method .
ABSTRACT
Objective To analysis 2 years follow-up clinical effects in endodontic lesion combined periodontal in treatment with Vitapex .Methods 112 patients with periodontal endodontic lesion combined periodontal were randomly divided into control group (56 cases ,75 teeth) and study group(56 cases ,77 teeth) .Treatment of Zinc oxide glycerin paste combined with gutta percha filling root canal was used in control group ,while Vitapex combined with gutta percha filling root canal was used in study group .After 2 years ,the clinical data of the two groups were analysed .Results The total effective rate of anterior and posterior in study group were significant higher than in control group(P<0 .05) .The total effective rate of of I type ,II type and III type lesions in study group were higher than in control group(P<0 .05) .Conclusion Treatment of Vitapex combined with gutta percha filling root canal in endodontic lesion combined periodontal has better clinical effectiveness to promote periapical and periodontal tissue healing than control group .
ABSTRACT
Objective To evaluate the clinical effect of Vitapex paste in the treatment of chronic periapical periodontitis.Methods Seventy patients who suffer from chronic periapical periodontitis were selected randomly.Their root canals were filled with Vitapex paste for almost one year.Results 68 teeth of the 70 patients received succesful results,and the success rate reached 97%.Conclusion The application of Vitapex paste in the treatment of chronic periapical periodontitis not only helps the healing of the inflammation,but also leads to a good closure of apical foramen.
