Bacterial Growth Inhibition

This study evaluated in vitro the antibacterial activity of 4 root canal filling materials for primary teeth - zinc oxide and eugenol cement (ZOE), Calen paste thickened with zinc oxide (Calen/ZO), Sealapex sealer and EndoREZ sealer - against 5 bacterial strains commonly found in endodontic infections (Kocuria rhizophila, Enterococcus faecalis, Streptococcus mutans, Escherichia coli and Staphylococcus aureus) using the agar diffusion test (agar-well technique). Calen paste, 1% chlorhexidine digluconate (CHX) and distilled water served as controls. Seven wells per dish were made at equidistant points and immediately filled with the test and control materials. After incubation of the plates at 37oC for 24 h, the diameter of the zones of bacterial growth inhibition produced around the wells was measured (in mm) with a digital caliper under reflected light. Data were analyzed statistically by analysis of variance and Tukey's post-hoc test (?=0.05). There were statistically significant differences (p<0.0001) among the zones of bacterial growth inhibition produced by the different materials against all target microorganisms. K. rhizophila was inhibited more effectively (p<0.05) by ZOE, while Calen/ZO had its highest antibacterial activity against E. faecalis (p<0.05). S. mutans was inhibited by Calen/ZO, Sealapex and ZOE in the same intensity (p>0.05). E. coli was inhibited more effectively (p<0.05) by ZOE, followed by Calen/ZO and Sealapex. Calen/ZO and ZOE were equally effective (p>0.05) against S. aureus, while Sealapex had the lowest antibacterial efficacy (p<0.05) against this microorganism. EndoREZ presented antibacterial activity only against K. rhizophila and S. aureus. The Calen paste and Calen/ZO produced larger zones of inhibition than 1% CHX when the marker microorganism was E faecalis. In conclusion, the in vitro antibacterial activity of the 4 root canal filling materials for primary teeth against bacterial strains commonly found in endodontic infections can be presented in a decreasing order of efficacy as follows: ZOE>Calen/ZO>Sealapex>EndoREZ.

Antimicrobial Effectiveness

The primary goal of endodontic treatment in primary teeth is to eliminate infection, and to retain the tooth in a functional state until their normal exfoliation time without endangering the permanent dentition or the general health of the child. The complexity of the pulp canal system in primary teeth presents a discerning problem for chemo-mechanical preparation. One of the factors determining the success of endodontic treatment in infected primary teeth is the sealing material that should encompass among other factors a potent bactericidal effect and the capacity to resorb along with the roots of primary teeth. This study evaluated the antimicrobial effectiveness of 5 root canal filling materials and a negative control agent against 23 strains of bacteria isolated from infected root canals of primary molar teeth and 3 non standard bacterial strains using agar diffusion assay. The materials were Zinc oxide and Eugenol (ZOE), Zinc oxide-Eugenol and Formocresol (ZOE+FC), Calcium hydroxide and sterile water (CAOH+H2O), Zinc oxide and Camphorated phenol (ZO+CP), Calcium hydroxide and Iodoform (Metapex) and Vaseline (Control). All the materials except Vaseline showed varied antimicrobial activity against the test bacteria. The zones of inhibition were ranked into 4 inhibition categories based on the proportional distribution of the data. All the 26 bacterial isolates were classified under 4 groups based on Aerobic/Anaerobic and Gram positive/Gram negative. Statistical analysis was carried out to compare the antimicrobial effectiveness between materials tested with each of the bacterial groupings. ZOE+FC produced strong inhibition against most bacteria when compared to ZOE, ZO+CP and CAOH+H2O. Metapex and Vaseline were found to be non inhibitory

Objective: Pulpectomy is the conservative treatment approach that retains and preserves the primary tooth in the dental arch in its normal function and non-pathologic state until its exfoliation. Over the years, pulpectomy has been performed using various instrumentation techniques. The aim of this study was to compare the quality of root filing and instrumentation time using Kedo-S files, Reciprocating files and K-files in primary teeth. Material And Methods: A randomized clinical trial was performed on 45 primary molars equally distributed for instrumentation with Kedo-S files, reciprocating files and K-Files. Immediate post-operative digital radiographs were taken to evaluate the quality of root filing and root canal instrumentation time was also recorded. Results: Mean instrumentation time with Kedo-S was 75.6 seconds, reciprocating file was 190.6 seconds and K-file was 95.4 seconds. Highest optimal fill was obtained with Kedo-S file group, highest overfill was obtained with Kedo-S group and highest under fill was obtained with reciprocating file group. Conclusion: Kedo-S rotary system provides better quality of root canal filling in minimum instrumentation time.KEYWORDS Pulpectomy; Primary teeth; Root canal filling; Rotary files.

ABSTRACT Aim The purpose of this study is to compare the efficacy of calcium hydroxide and zinc oxide eugenol as a root canal filling material in primary teeth using endodontic pressure syringe system. Materials and methods A total of 40 primary mandibular molars were selected and divided into two groups-group I (calcium hydroxide was used as root canal filling material) and group II (zinc oxide eugenol used as canal filling material). Clinical review was undertaken at 1, 3, 6 and 9 months interval for evaluating pain, tenderness, mobility and any other sign of pathology. Radiographic examination was done at interval of 3, 6 and 9 months for the evaluation of any change in the radiolucency around the apices and inter-radicular space. Resorption of root and filling material was also assessed. Results Reduction in the clinical symptoms were noted in both groups (p < 0.01). All the 20 cases in group I demonstrated a decrease in size of radiolucency. However in group II, an increase in radiolucency was observed in 2 teeth at 3 months radiographic examination. Further no decrease in the size of radiolucency was noticed at subsequent follow-up visits. Complete resorption of overfilled material was observed at the 3 months radiographic examination for group I whereas partial resorption of overfilled material was seen at 6 months radiographic examination for group II. Conclusion The findings of the present study indicate that calcium hydroxide could be used exclusively or as an alternative to zinc oxide eugenol as a root canal filling material for the primary teeth.

The aim of this study was to compare the efficiency in both, preparation time and root canal shape, when using the Nickel Titanium (Ni-Ti) rotary and K-Files hand instrumentation on root canal preparation of single rooted primary teeth. Material and methods: Sixty single rooted primary teeth were selected and divided into two equal groups: Group (I) 30 teeth instrumented with manual K- files and group (II) 30 teeth instrumented with Ni-Ti rotary files (ProFile 0.04). Instrumentation times were calculated and root canal impressions were taken with light bodied silicone in order to evaluate the shape. The data was analyzed with SPSS program using the t-test and the Chi-square test to compare their means. Results: The preparation time with group (I) K- files was significantly higher than in group (II) rotary files (ProFile 0.04), with a p= .005. The ProFile system showed a significantly more favorable canal taper when compared to the K-files system (P= .002). Conclusions: The use of rotary files in primary teeth has several advantages when compared with manual K files: the efficiency in both, preparation time and root canal shape. 1. A decreased working time, that helps maintain patient cooperation by diminishing the potential for tiredness. 2. The shape of the root canal is more conical, favoring a higher quality of the root canal filling, and increasing clinical success.
