ABSTRACT
Formocresol is widely used in primary teeth pulpotomies; however it is known to have several side effects. The purpose of this study was to assess pulpal changes of primary teeth pulps after pulpotomy with sodium hypochlorite and formocresol. In this randomized clinical trial, 22 teeth were selected. These teeth were randomly divided into 2 groups [formocresol; n=11 and sodium hypochlorite n=11]. Two months post-operatively teeth were extracted and pulpal responses were evaluated by recording the degree of inflammation and extent of pulpal involvement. Dentinal bridge formation was also evaluated. Finally the data was analyzed with McNemartest. The formocresol group demonstrated mild inflammation in 4 cases whereas sodium hypochlorite had mild inflammation in six cases. Severe inflammation was only found in 1 case in the sodium hypochlorite group, but it was present in 4 cases in the formocresol group. In sodium hypochlorite group there were no cases of necrosis, and dentinal bridge was found in 3 cases, unlike, the formocresol group which had necrosis but no dentinal bridge formation. Based on the results of this study sodium hypochlorite may be a suitable solution for conducting pulpotomy in primary teeth
ABSTRACT
Background and Aim: Equipments and surfaces in dental clinics and centers are always in risk of contamination. When there is no possibility of sterilizing them, fast acting disinfecting agents are used. In this study, antibacterial effect of a new disinfecting solution, named Nanex,against streptococcus mutans and pseudomonas aeroginosa was compared with pure Nano silver solution and Deconex 53 plus
Materials and methods: In this experimental study, in order to determine the effective antibacterial concentration , serial dilution technique ,evaluation of [MIC] and [MBC] were used. Finally bacterial growth was assessed
Results: The # 4 solution [containing 100 ppm Nano silver and 2% Deconex] showed the least MIC and MBC for streptococcus mutans. The # 7 solution [containing 133 ppm Nano silver and 1% Deconex] showed the least MIC and MBC for psuedomonas aerogenosa
Conclusion: Thus, antibacterial effect of Nanex solution was more potent and effective than pure solution of nano silver and deconex
ABSTRACT
Pulpotomy of carious primary teeth with an exposed pulp is a common treatment option. Pulpotomy has been conducted with various medicaments over the years. The aim of this study was to evaluate clinical and radiographic success of primary vital pulpotomy with ProRoot and Root MTA. In this randomized clinical trial, children aged between 3-7 years who met the inclusion criteria were enrolled. A total of 70 teeth were deemed suitable under the inclusion criteria and teeth were randomly divided into the 2 groups; ProRoot and Root MTA. Pulpotomy was performed and immediately followed by coronal amalgam restoration. The clinical and radiographic follow ups were conducted 6, 12, 18, 30 months post-operatively. The data were analyzed using Exact Fisher test. At the final follow up, 28 teeth in ProRoot MTA and 26 teeth in Root MTA were evaluated. In the Root MTA group, 1 tooth had exfoliated and one had an abscess and furcal radiolucency radiographically. In ProRoot MTA group, external resorption was observed in 1 tooth. Statistical analysis did not show significant difference in success rate between 2 groups after 30 months. The success rates of Root and ProRoot MTA are similar, indicating that pulpotomy can be carried out successfully in both primary molars
