Comparative evaluation of clinical and radiological success of zinc oxide-ozonated oil, modified 3mix-mp antibiotic paste, and vitapex as treatment options in primary molars requiring pulpectomy: An in vivo study.

OBJECTIVES: The aim of this study was to evaluate the clinical and radiographic success of zinc oxide-ozonated oil (ZnO-OO), modified 3Mix antibiotic paste, and Vitapex in treatment of primary molars requiring pulpectomy. METHODS: Sixty-four primary molars of forty three children aged between 4 and 8 years with pulpally involved primary molars requiring root canal procedures were treated with ZnO-OO, modified 3Mix-MP paste, and Vitapex. The subjects were followed up clinically at 1, 6, and 12 months whereas radiographically at 6 and 12 months, respectively. RESULTS: The results showed that the clinical and radiographic success rates of ZnO-OO and Vitapex over 12 months period of observation were 100% whereas, for modified 3Mix-MP paste, the results were 95.8% and 79.2%, respectively. CONCLUSION: On the basis of the overall success rates of all the three medicaments, following order of performance can be inferred clinical success and radiographical success:- ZnO-OO = Vitapex > modified 3MIX-MP paste.

Comparative Evaluation of Caries Status in Primary and Permanent Molars in 7-8-year-old Schoolchildren of Shimla Using Caries Assessment Spectrum and Treatment Index.

BACKGROUND: A new epidemiological index is introduced for full assessment of dental caries which is known as caries assessment spectrum and treatment (CAST). "Spectrum" is considered backbone of this index as it covers from no lesion to advanced stage progression of caries. We aimed to evaluate and compare the status of caries in primary and permanent molars of 7-8-year-old schoolchildren of Shimla using CAST index and to find if any correlation exists between the status of caries in evaluated teeth. METHODS: Three hundred and one schoolchildren with age group of 7-8 years were selected from schools in Shimla. CAST codes were determined for primary molars and first permanent molars. The distribution of CAST codes in the examined molars is correlated with the help of Spearman's rank correlation coefficient. The level of statistical significance was established at P < 0.05. The intraexaminer reliability was determined by the unweighted kappa coefficient. RESULTS: Caries was assessed in 6.3%-12.3% of the permanent molars in contrast to primary molars, in which caries was near about 50%. The correlation was stronger for first and second deciduous molars for the right side of the mouth than the left side (r = 0.293 and 0.257 in the maxilla and 0.503 and 0.319 in the mandible [P < 0.001], respectively, while correlation for teeth in opposite jaws was moderate [r = 0.20-0.47]). The intraexaminer reliability was examined (k = 0.90 for the primary and 0.85 for permanent molars). CONCLUSION: The correlation between primary and permanent molars regarding the caries status in primary molars is weak while strongest correlation was present on the right side of the mouth for first and second deciduous molars. The study also showed the applicability of the CAST index in epidemiological surveys.

In Search of a Novel Substitute: Clinical and Radiological Success of Lesion Sterilization and Tissue Repair with Modified 3Mix-MP Antibiotic Paste and Conventional Pulpectomy for Primary Molars with Pulp Involvement with 18 Months Follow-up.

OBJECTIVES: The aim of this study was to evaluate the clinical and radiographic success of zinc oxide (ZnO)-ozonated oil, modified 3Mix antibiotic paste, and vitapex in the treatment of primary molars requiring pulpectomy. METHODS: Sixty-four primary molars of forty-three healthy children aged between 4 and 8 years with primary molars requiring root canal procedure were treated with ZnO-ozonated oil, modified 3Mix-MP antibiotic paste, and vitapex. Clinical follow up was done at 1, 6,12 months and 18 months while radiographical follow-up was done at 6,12 and 18 months, respectively. RESULTS: The results showed that the clinical success rates of ZnO-ozonated oil, modified 3Mix-MP paste and vitapex were 95.5%,89.5% and 100% respectively and radiographical success rates were 94.4%,80.95% and 100% respectively after 18 months period of observation. CONCLUSION: The overall success rates of ZnO-ozonated oil, vitapex and modified 3Mix antibiotic paste were comparable.
