title: Evaluation of efficacy of Aloe Vera as a Disinfectant by Immersion and Spray methods on Irreversible Hydrocolloid Impression Material and its Effect on the Dimensional Stability of Resultant Gypsum Cast An in Vitro Study
abstract: The need to use a natural alternative for disinfecting dental impression materials, which should be biocompatible and effective, led us to evaluate the efficacy of Aloe vera as a disinfectant by immersion and spray method on alginate impression material and its effect on the dimensional stability of the resultant gypsum cast. The efficacy of the disinfection procedures against Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans was evaluated by determining the number of colony forming units (CFU) recovered after disinfection of alginate discs inoculated with 1x106 CFU for defined intervals with aloe vera solution (99.96% Dimensional stability was determined from the mean percentage deviation of three measurements that were taken between the fixed points on the casts using a traveling microscope and compared with corresponding measurements from the master model and controls. Statistical analysis of data was determined by analysis of variance. We found out that there is a mean percentage reduction in colony count of S. aureus, P. aeruginosa, and C. albicans after 3 minutes of immersion in aloe vera and after 3 minutes spray disinfection. Complete elimination of all the microorganism cells after 7 min immersion and spray disinfection. There was a statistically significant difference in the increase of the mean anteroposterior (AP) and cross arch (CA) dimension after 3 and 7 minutes immersion in aloe vera. Spraying with aloe vera for 7 minutes was proved to be the most effective disinfection procedure without altering dimensional stability.

title: Role of Herbal Agents Tea Tree Oil and Aloe vera as Cavity Disinfectant Adjuncts in Minimally Invasive Dentistry An In vivo Comparative Study.
abstract: The prevention and control of caries necessitates the elimination of cariogenic bacteria and cavity disinfectants have proved to play a major role in achieving the goal. The use of phytotherapy is trending and many natural products have shown anti microbial properties which can be used as cavity disinfectant in the field of dentistry.  The aim of this study was to compare the efficacy of herbal antibacterial agents (Tea Tree Oil (TTO) and Aloe vera) with commercially available 2% chlorhexidine (CHX) as cavity disinfectant for use in minimally invasive dentistry.  The study included three test groups, Group I (2% chlorhexidine) Group II (tea tree oil) Group III (Aloe vera gel) with a control group (distilled water) Ten patients with atleast one tooth with an occlusal or occluso proximal lesion suitable for Atraumatic Restorative Treatment (ART) were selected for each group, dentinal samples were collected using sterile spoon excavators at three stages from each tooth viz. pre excavation, post excavation and post disinfection of the cavities. These dentinal samples were subjected to microbiological analysis for Total Viable Count (TVC) The data collected were statistically analysed using ANOVA and Bonferroni post hoc test.  The results of present study showed that there was a statistically significant reduction in TVC when compared between pre and post excavation in all the groups (p<0.05) and post excavation and post disinfection in all the test groups (p<0.05) (except control group) Post disinfection, 2% chlorhexidine showed highest reduction in TVC followed by 1% tea tree oil and aloe vera gel.  Natural antibacterial agents like tea tree oil and aloe vera could be effectively used as cavity disinfectants which will help in minimizing secondary caries and rendering a long term restorative success.

title: Comparative evaluation of effect of chlorhexidine, Azadirachta indica (neem) and Aloe barbadensis miller (Aloe vera) on resin dentin bond stabilization using shear bond testing: An in vitro study
abstract: Cavity disinfectants help to remove the microbial remnants; hence, its use prior to any restoration is valuable, and a search for alternative to chlorhexidine (CHX) is required which may be more efficacious and can overcome the drawbacks of CHX.  The aim of this study was to evaluate the effect of application of three different cavity disinfectants in a clinically relevant time period on the immediate and delayed shear bond strengths (SBSs) of an etch and rinse adhesive system to dentin.  For SBS testing, flat coronal dentin surfaces were prepared in two hundred extracted human molars. Specimens were randomly assigned to four groups according to the disinfectant used: Group I: Control (no disinfectant) Group II: 2% CHX solution, Group III: Aloe barbadensis miller (Aloe vera) solution, and Group IV: Azadirachta indica (neem) solution. Specimens were bonded using Prime and Bond NT adhesive which was employed according to the manufacturer's instructions. Resin composite cylinder buildups were done in all the samples. The modes of failure were noted after visual examination using a binocular stereomicroscope. Samples were also analyzed under scanning electron microscope for observation of resin dentin interface. SBS results were analyzed using one way ANOVA followed by Tukey's post hoc test.  The results showed that CHX, Aloe vera, and neem had improved bond strengths as compared to the control group for both immediate and delayed SBSs.  From the results of the study, the authors concluded that Aloe vera and neem can be used as alternative cavity disinfectants to CHX.

title: Ethanolic extracts of Aloe vera and propolis as cavity disinfectants: An in vitro study
abstract: Though a large number of agents including chlorhexidine have been used for cavity disinfection during restorative procedures, till date none has proved to be "ideal." Thus, there is a need for an alternative cavity disinfectant, which is safe, effective, and economic. Herbal extracts of Aloe vera and propolis have shown the potential to be used as cavity disinfectants but not much is known about them. The aim of this study was to evaluate and compare the antibacterial activity of ethanolic extracts of Aloe vera and propolis against S. mutans and L. acidophilus, along with assessing the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)  The study included three groups: 2% chlorhexidine solution (group I) ethanolic extract of Aloe vera (group II) and ethanolic extract of propolis (group III) An MIC test was carried out using tissue culture microplates and serial dilution technique and later to MBC, an aliquot of each incubated well with concentrations higher than MIC was subcultured on brain heart infusion (BHI) medium. Antibacterial assay was carried out using agar disk diffusion technique and zones of inhibition were determined. One way analysis of variance (ANOVA) was used for intergroup comparison followed by post hoc Tukey's test for groupwise comparison.  Group II and Group III showed bacteriostatic effect but no bactericidal effect against both S. mutans and L. acidophilus. There was a significant difference in the antibacterial activity against both the tested microorganisms among all the groups, the highest being in group I followed by group II and group III.  Ethanolic extracts of Aloe vera and propolis are only bacteriostatic and their antibacterial efficacy is inferior to chlorhexidine against both S. mutans and L. acidophilus.

title: Disinfection of Dental Unit Water Line Using Aloe Vera: In Vitro Study
abstract: Dental unit waterlines may be heavily contaminated with microorganisms and are a potential source of infection for both practicing staff and immunocompromised patients particularly. Contamination of dental unit water lines could be inhibited with the use of disinfectants. The present study investigates the effect of aloe vera based disinfectant in reducing the microbial growth in dental unit water lines (DUWLs)  To compare the efficacy of aloe vera, hydrogen peroxide (H2O2) and 5% sodium hypochlorite (NaOCl) in controlling microbial contamination of DUWLs.  After obtaining baseline water samples, the dental unit waterlines were treated with aloe vera, 10% hydrogen peroxide, and 5% sodium hypochlorite. Each of the three disinfectants was used in increasing concentrations and their inhibiting effect was compared. Water samples were analyzed for microbiological quality by the total viable count (TVC) method.   There was significant reduction in mean CFU/ml when treated with disinfectants each for a period of one week. Aloe vera solution was found to be the most effective in reducing the microbial colonies.  Improving the water quality from dental unit water lines is of considerable importance; chemical based disinfectants can be replaced with herbal disinfectants for treating microbial contamination in dental unit waterlines.

title: Effect of Different Chemical and Herbal Disinfectant Solutions on the Mechanical and Physical Properties of Gutta percha: An In Vitro Study
abstract: Ab s t r Ac t  To evaluate the effect of 5.25% sodium hypochlorite (SH) 90% aloe vera (AV) gel, and 2% chlorhexidine (CHX) as disinfecting solutions on the physical and mechanical properties of gutta percha (GP)  A total of 80 GP cones of size F3 ProTaper were obtained from sealed packet as four different groups. The experimental groups were disinfected with 5.25% SH, 90% AV gel, and 2% CHX except control group. The tensile strength of GP cones was measured under universal testing machine, and the surface texture was analyzed under stereomicroscope.  Mean tensile strength in the order of lowest to highest was 9.13 for 5.25% SH, 13.05 for 2% CHX, 13.56 for 90% AV, and 16.44 for control group. The 5.25% SH group showed pitting on surface and control group and AV group showed negligible pitting, whereas 2% CHX showed moderate pitting on surface under stereomicroscope.  Aloe vera gel at 90% can be considered as a safer GP cone disinfectant.  The main objective of root canal treatment depends on the elimination of microorganism from the root canal system. To obtain aseptic condition, disinfection of GP cone is required, which may get contaminated during handling. Aloe vera gel can be a promising herbal disinfecting solution for GP cone without affecting any physical and mechanical properties of it.

title: Comparative evaluation of tensile strength of Gutta percha cones with a herbal disinfectant
abstract: To evaluate and compare the tensile strength values and influence of taper on the tensile strength of Gutta percha (GP) cones after disinfection with sodium hypochlorite (SH) and Aloe vera gel (AV)  Sixty GP cones of size 110, 2% taper, 60 GP cones F3 ProTaper, and 60 GP of size 30, 6% taper were obtained from sealed packs as three different groups. Experimental groups were disinfected with 5.25% SH and 90% AV gel except the control group. Tensile strengths of GP were measured using the universal testing machine.  The mean tensile strength values for Group IA, IIA and IIIA are 11.8 MPa, 8.69 MPa, and 9.24 MPa, respectively. Results were subjected to statistical analysis one way analysis of variance test and Tukey post hoc test. 5.25% SH solutions decreased the tensile strength of GP cones whereas with 90% AV gel it was not significantly altered.  Ninety percent Aloe vera gel as a disinfectant does not alter the tensile strength of GP cones

title: A Comparative Evaluation of Different Chemical Agents and Herbal Products in Disinfecting Gutta Percha Cones: An In Vitro Study
abstract: The main aim of this study was to compare and evaluate different chemical agents and herbal products in disinfecting gutta percha (GP) cones through an in vitro study.  this study, 160 GP cones were taken in test tubes, which were contaminated with Enterococcus faecalis inocula, prepared by dissolving it in Brain Heart Infusion (BHI) broth. The GP cones were then taken from the test tubes and dried on Whatman filter paper no. 1 and were divided into four groups according to the decontaminant used for the study group 1 (5% sodium hypochlorite [NaOCl] group 2 (2% chlorhexidine) group 3 (propolis) and group 4 (Aloe vera) which were further subdivided into subgroups on the basis immersion time periods of 1 and 10 minutes. The GP cones were then again dried and taken in the test tubes containing freshly prepared BHI broth to check the turbidity.  It was found that 2% chlorhexidine was the most effective disinfectant against E. faecalis, 5% NaOCl was the second best disinfectant followed by propolis, while Aloe vera had not shown any effect as GP disinfectant.  Since 2% chlorhexidine showed better disinfection efficacy against E. faecalis than 5% NaOCl, it can be recommended for chairside disinfection of GP. One minute immersion of GP in 2% chlorhexidine is sufficient for elimination of E. faecalis.
