Effect of Herbal Water, Ozonated Water, Water, and Chlorhexidine Mouthrinses on Oral Health Status of Children: A Randomized Controlled Trial

Herbal Mouthrinses for Prevention of Dental Caries in Children and Adolescents: A Systematic Review

The primary aim of this study was to evaluate the effectiveness of herbal mouthrinses (HMR) on caries prevention in children and adolescents. In addition, this systematic review assessed its effectiveness in remineralization of white spot lesions, reduction of halitosis, and improving gingival and periodontal health in orthodontic patients and patients with special healthcare needs (SHCN). A comprehensive bibliographic search was conducted in PubMed, Cochrane Central, EMBASE, AMED, ProQuest, CINAHL, AYUSH, Digital Helpline for Ayurveda Research Articles (DHARA), and Clinical Trial Gov databases. A total of 3,918 titles were identified during the initial search. Of these, 32 studies were selected for quality assessment. A total of 5,038 participants from 10 countries were thus included in this review, with 22 (66.7%) studies conducted in India. All included studies were published between 2004 and 2021. Included studies investigated the effect of HMR on caries increments, which record decayed, missing, filled (DMF) [International Caries Detection and Assessment System (ICDAS)], decayed, missing, filled teeth/surfaces (DMFT/S), and incipient caries. Changes in bacterial count (Streptococcus mutans and Lactobacillus) and alterations in levels of Candida albicans from saliva or plaque samples were also reported. The effect of HMR on gingival and plaque indices among adolescents undergoing orthodontic treatment and children with SHCN was reported in two studies. The variance in the HMR formula across studies, short follow-up period, and limiting grade of evidence do not allow for conclusive evidence of the efficacy of HMR. This warrants high-quality randomized controlled trials (RCTs) with longer intervention periods involving children under 6 years to yield more conclusive results.

Effect of 20-ppm ozone and 1% chlorhexidine gels on plaque index and Streptococcus mutans counts in the dental plaque in 6-12-year-old children: A randomized, double-blind clinical trial

Background

One of the methods to control dental caries is to use ozone. Since it is difficult for children to use mouthwashes, the present study aimed to evaluate 20-ppm zone and 1% chlorhexidine (CHX) gels' effects on the plaque index and Streptococcus mutans counts in 6-12-year-old children.

Methods

In the present double-blind clinical trial, 165 children, 6-12 years of age, referring to the Department of Pediatric Dentistry, Tabriz Faculty of Dentistry, were selected based on inclusion and exclusion criteria and randomly assigned to three groups: ozone gel, CHX gel, and control. The subjects were instructed to place an adequate amount of the gels on all the surfaces of their teeth with one clean finger. The patients and evaluators were blinded to the study groups. The plaque index and S. mutans counts in plaque samples were determined before intervention and three weeks after intervention on the buccal surface of the most posterior maxillary tooth (left or right). S. mutans counts were determined by culture. STATA software version 14 was used for statistical analyses using Wilcoxon, Kruskal-Wallis, and post hoc Dum tests. Statistical significance was defined at P<0.05.

Results

The 20-ppm ozone and 1% CHX gels significantly decreased dental plaque compared to the control group (P<0.05), and their effects were similar (P>0.05). These gels significantly decreased the colonies and bacterial counts of S. mutans (P<0.05).

Conclusion

The performance of 20-ppm ozone gel in decreasing the dental plaque and S. mutans counts was similar to 1% CHX gel.

Efficacy of ozonated water as a PS in photodynamic therapy: A tool for dental caries management? An in vitro study

Background

The most prevalent noncommunicable disease in the world is dental caries; and when it is not adequately treated, it is usually associated with tooth loss or severe dental lesions. In fact, expensive care or tooth extraction may be necessary due to the negative effects dental caries have on general health. This is due to its frequent pain and secondary bacterial infections. The aim of this study was to investigate the activity of ozonated water as such and in combination with appropriate light radiation so as to perform a photodynamic treatment (PDT) against the cariogenic bacterium Streptococcus mutans.

Design and methods

This work has been performed in vitro by using an S. mutans strain mainly structured in a biofilm status, reproducing the natural condition of the tooth infection. The ozone was tested at three different concentrations by using a commercial device able to generate different O3 formulations in water. The PDT treatment requires an appropriate light wavelength, evaluated in this work through the UV-Vis adsorption spectrum of the ozonated water.

Results

The obtained results suggested an effective and synergic property of O3 and light at 460-470 nm against this microorganism. The most antibiofilm activity was observed using a concentration of ozone of 0.06 mg/L alone as well as with PDT treatment.

Conclusions

The results are encouraging for additional research and in vitro/in vivo fresh experimental investigations to perform an exhaustive antimicrobial treatment protocol against the S. mutans tooth infection.

Efficacy of ozonated water over chlorhexidine mouth rinse in chronic gingivitis patients - A comparative clinical study

Aim

This study aimed to compare the efficacy of ozonated water mouth rinse over chlorhexidine mouth rinse against the accumulation of plaque in chronic gingivitis patients.

Materials and methods

A total of 30 patients with chronic generalized gingivitis were choosen for the study. The duration of this study was 15 days and was divided into three groups. Group 1 patients were advised to rinse with ozonated water¸ group 2 with a chlorhexidine mouth rinse and group 3 with water for 15 days. The clinical parameters like plaque index, gingival index, and bleeding index were recorded at baseline, 7th, and 15th day respectively. Saliva samples were collected for microbial culture at baseline that is before mouth rinse and on the 15th day that is after using mouth rinse from each patient.

Results

The statistical analysis was performed by using ANOVA and Bonferroni's Post Hoc test on 30 patients at the end of the 15^thday. There was a significant decrease in mean plaque, gingival, and bleeding scores in group 2 patients that are chlorhexidine mouth rinse. There was also a decrease in the microbial culture at the end of the 15th day in patients with chlorhexidine mouth rinse compared to ozonated water.

Conclusion

The results of this study demonstrate that ozonated water was less effective compared to chlorhexidine mouth rinse in reducing plaque in gingivitis patients. But ozonated water can be used as an alternative to CHX.
