Background
Toothbrushes are the most commonly used mechanical plaque control methods, and they are said to harbor microorganisms if not stored properly following usage.
Objective
An assessment of the influence of a decontaminating agent (sterile water (control)/chlorhexidine mouthwash/herbal mouthwash) on the properties of toothbrush bristles following storage for 24 hrs by means of scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR).
Methodology
The study involves a total of 24 slim soft toothbrushes (six samples per group) with different decontaminating agents: Group 1: Vented container, Group 2: Sterile water, Group 3: 0.2% Chlorhexidine mouthwash, and Group 4: Herbal mouthwash. The toothbrushes were stored in their respective containers for 24 hours, following which, snippets of toothbrush bristles were collected and tested for the evaluation of wear using SEM and the biochemical alteration occurring in the bristles was assessed using FTIR.
Results and conclusion
The Group 2 and Group 3 samples showed significant wear (Score 2) under SEM evaluation, and FTIR spectroscopy evaluation revealed that changes occur in the fingerprint region of infrared spectroscopy owing to chemical bond alteration following decontamination. Considering the benefits we acquire in terms of microbial load reduction, decontamination is recommended, though it might necessitate frequent changing of toothbrushes.
The objective of this literature review was to critically review the evidence available in the literature regarding the expediency of erbium family of lasers for root bio modification as a part of periodontal therapy. The literature search was performed on the Pubmed using MeSH words such as "lasers/therapeutic use, scaling, dental calculus, tooth root/anatomy and histology, ultrasonic therapy". The studies were screened and were grouped as follows: those evaluating a) efficacy for calculus removal with the Erbium family of laser b) root surface changes following Er YAG and Er Cr YSGG application c) comparative studies of the Er YAG, Er Cr YSGG lasers versus conventional methods of root surface modification d) Bio compatibility of root surface following Erbium laser treatment e) Studies on the combined efficacy of laser root modification with conventional methods towards root surface bio-modification f) Studies on effectiveness of root surface bio-modification prior to root coverage procedures. In conclusion, the erbium family has a proven anti-bacterial action, predictable calculus removal, minimal root substance removal, and appears to favor cell attachment. The Erbium family of lasers appears to be a useful adjunct for the management of periodontal disease.
Context:Bone grafting materials which have an inherent anti-microbial property against initial colonizers of plaque bacteria would be useful in regenerative periodontal surgical procedures.Aims:This study was performed to analyze the antibacterial property of a Perioglas™ against a common oral commensal Streptococcus salivarius (early colonizer).Settings and Design:
In vitro observational study.Materials and Methods:Perioglas™ (in various concentrations) was assessed for its antibacterial property against the ATCC 13419 strain of S. salivarius. The anti-microbial activity was analyzed in terms of reduction in colony-forming units in culture plates and smear following a 24 h incubation at 37°C.Statistical Analysis Used:Observational study - No statistical analysis applicable.Results:The bioactive glass (BAG) exerted an antibacterial effect against the S. salivarius in the suspending media and smear. The antibacterial activity of BAG increased in proportion with its concentration.Conclusions:Perioglas™ demonstrated a considerable antibacterial effect against S. salivarius at 50 mg/mL concentration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
