ABSTRACT
BACKGROUND: Endodontic therapy treats inside of the tooth and its success is based upon the triad of thorough canal debridement, effective disinfection, and obturation of the canal space. Thus, one of the most important steps is biomechanical preparation, which is the key stage of endodontic treatment with a predictive success factor if performed properly. AIM: The aim of the study is to evaluate and compare the cleaning efficiency of different file systems in terms of remaining dentin thickness. MATERIALS AND METHODS: A total of thirty permanent extracted anterior teeth were taken for the study and was divided into three groups - Group I - Manual Protapers, Group II - Rotary Mtwo, and Group III - Reciprocating WaveOne file systems. Pre-cone-beam computed tomography (CBCT) scan was taken followed by biomechanical preparation by the respective file groups. Post-CBCT scan was taken and the pre- and post-CBCT scans were compared for remaining dentin thickness. Data were analyzed with ANOVA (P = 0.001). STATISTICAL ANALYSIS USED: ANOVA test was used in this study. RESULTS: Protaper showed minimum reduction in dentin thickness followed by Mtwo and WaveOne showed maximum reduction in dentin thickness, but the intergroup comparison was found to be highly insignificant. CONCLUSION: WaveOne is a highly recommended rotary endodontic instrument which does not cause significant lowering in remaining dentin thickness after biomechanical preparation.
ABSTRACT
BACKGROUND: Herbs have renewed importance in this modern era for their antimicrobial properties and fewer side effects. So a novel idea to use these herbs for pulpectomy; was implemented. There are chances of failure of pulpectomy due to inefficient removal of microbial load. Thus, for a successful endodontic treatment, obturating material with optimum antimicrobial properties is advocated in the present study. AIM: To compare and evaluate the antibacterial efficacy of zinc oxide eugenol, zinc oxide with tulsi extract and zinc oxide with aloe vera as obturating materials against E. faecalis bacteria. MATERIALS AND METHODS: Antimicrobial efficacy of zinc oxide eugenol as control, zinc oxide with tulsi extract and zinc oxide with aloe vera as experimental groups were assessed by using agar diffusion method. The statistical analysis was done. RESULTS: Intergroup comparison revealed significant difference amongst all the groups except between zinc oxide eugenol and zinc oxide with tulsi extract. Zinc oxide eugenol had significantly higher zone of inhibition among all the groups. CONCLUSION: According to results obtained from the present study can be summarized as follows: Zinc oxide eugenol > Zinc oxide with tulsi extract > Zinc oxide with aloe vera.
ABSTRACT
AIM: The purpose of this study is to compare the effect of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP, Tooth Mousse) containing and casein phosphopeptide-amorphous calcium phosphate with fluoride (CPP-ACPF, Tooth Mousse Plus) containing pastes on dental erosion. MATERIALS AND METHODS: Thirty permanent non-carious premolars indicated for orthodontic extraction were included in this study and were sectioned in mesiodistal direction vertically. After immersion in the carbonated drink for 14 min, samples were treated with various remineralizing pastes which were CPP-ACP containing paste (Tooth Mousse) and CPP-ACPF containing paste (Tooth Mousse Plus) according to the manufacturer's instructions. Vickers Microhardness was recorded at baseline, after exposure to erosive drink and after treatment with remineralizing pastes. Data obtained was statistically analysed using Student t-test with a level of significance set at p < 0.05. RESULTS: CPP-ACP (Tooth Mousse) and CPP-ACP with fluoride (Tooth Mousse Plus) resulted in 30.52% and 38.98% increase in post-erosion microhardness values respectively. The remineralizing potential of CPP-ACP with fluoride containing paste (Tooth Mousse Plus) was significantly better than that of CPP-ACP containing paste (Tooth Mousse) (p < 0.05). CONCLUSION: Casein phosphopeptide-amorphous calcium phosphate with fluoride (CPP-ACPF, Tooth Mousse Plus) can be recommended to be used in preventing erosive tooth wear from acidic beverages.
ABSTRACT
The use of minimally invasive procedures and attention to patient comfort are of great importance, especially for dental treatment in young children. This has led to the development of chemomechanical methods for caries removal. Aim: To evaluate and compare the antimicrobial efficacy, efficacy in terms of time consumption and pain perception of chemomechanical caries removal agent Papacarie® and conventional method of caries removal. Methods: Subjects for this study were chosen from children admitted to dental clinic for restorative procedures. Forty children (age 4-8 years) with early childhood caries were included in this study. Two primary teeth with comparable degrees of carious destruction were chosen in each child for caries removal with either Papacarie® or rotary instruments. The time taken for caries removal was measured using stopwatch. Pain response during caries removal was evaluated using the Wong Baker Face Pain Scale. Dentin samples of both groups were taken prior to, and after caries removal for microbiological analysis. Results The time taken for caries removal in chemomechanical caries removal method was three times longer than the conventional method. Pain score during chemomechanical method of caries removal was 1.525 as compared with 6.65 when conventional method was used. The antimicrobial efficacy of chemomechanical caries removal was significantly similar to conventional method. Conclusions: Papacarie® can be an effective clinical alternative treatment for the removal of occlusal dentinal caries in cavitated primary molars.
