Comparative study between photodynamic therapy and the use of probiotics in the reduction of halitosis in mouth breathing children: Study protocol for a randomized controlled clinical trial.

ABSTRACT:

Introduction

Halitosis is a term that defines any odor or foul smell the emanates from the oral cavity, the origin of which may be local or systemic. One of the causes of local or oral halitosis is low salivary flow and dry mouth, which is also one of the complaints of individuals with the mouth-breathing habit. The aim of this study is to determine the effectiveness of antimicrobial photodynamic therapy (aPDT) and the use of probiotics for the treatment of halitosis in mouth-breathing children.

Methods

Fifty-two children between 7 and 12 years of age with a diagnosis of mouth breathing and halitosis determined through an interview and clinical examination will be selected. The participants will be divided into 4 groups: Group 1-treatment with brushing, dental floss and tongue scraper; Group 2-brushing, dental floss and aPDT applied to the dorsum and middle third of the tongue; Group 3-brushing, dental floss and probiotics; Group 4-brushing, dental floss, aPDT and probiotics. The use of a breath meter and microbiological analysis of the tongue coating will be performed before, immediately after treatment and 7 days after treatment. The quantitative analysis will involve counts of colony-forming bacteria per milliliter and real-time polymerase chain reaction. The normality of the data will be determined using the Shapiro-Wilk test. Parametric data will be submitted to analysis of variance and nonparametric data will be compared using the Kruskal-Wallis test. The results of each treatment in the different periods of the study will be compared using the Wilcoxon test.

Discussion

Due to the low level of evidence, studies are needed to determine whether treatment with aPDT using annatto as the photosensitizer and blue led as the light source is effective at diminishing halitosis in mouth-breathing children.

Project description:BackgroundHalitosis is an unpleasant breath odour that can interfere with the professional life, social life and quality of life of people who suffer from it. A modality of treatment that has been increasing in dentistry is antimicrobial photodynamic therapy (aPDT). Bixa orellana, popularly known as "urucum" is a plant native to Brazil. The seeds are used to produce a dye that is largely used in the food, textile, paint and cosmetic industries. The aim of this study is to verify whether aPDT with Bixa orellana extract and blue light-emitting diodes (LEDs) is effective in reducing halitosis. This method will also be compared with tongue scraping, the most commonly used conventional method for tongue coating removal, and the association of both methods will be evaluated.Methods/designA randomized clinical trial will be conducted at the dental clinic of the Universidade Nove de Julho. Thirty-nine patients will be divided by block randomization into three groups (n = 13) according to the treatment to be performed. In Group 1, tongue scraping will be performed by the same operator in all patients for analysis of the immediate results. Patients will also be instructed on how to use the scraper at home. Group 2 will be treated with aPDT with Bixa orellana extract and the LED light curing device: Valo Cordless Ultradent®. Six points in the tongue dorsum with a distance of 1 cm between them will be irradiated. The apparatus will be pre-calibrated at wavelength 395-480 nm for 20 s and 9.6 J per point. In Group 3, patients will be submitted to the tongue scraping procedure, as well as to the previously explained aPDT. Oral air collection with the Oral Chroma™ and microbiological collections of the tongue coating shall be done before, immediately after and 7 days after treatment for comparison.DiscussionHalitosis treatment is a topic that still needs attention. The results of this trial could support decision-making by clinicians regarding aPDT using blue LEDs for treating halitosis on a daily basis, as most dentists already have this light source in their offices.Trial registrationClinicalTrials.gov, NCT03346460 . Registered on 17 November 2017.

Project description:BackgroundHalitosis is a common problem that affects a large portion of the population worldwide. The origin of this condition is oral in 90% and systemic in 10% of cases. The unpleasant odor is mainly the result of volatile sulfur compounds produced by Gram-negative bacteria. However, it has recently been found that anaerobic Gram-positive bacteria also produce hydrogen sulfide (H2S) in the presence of amino acids, such as cysteine. Light, both with and without the use of chemical agents, has been used to induce therapeutic and antimicrobial effects. In photodynamic therapy, the antimicrobial effect is confined to areas covered by photosensitizing dye. The aim of the present study is to evaluate the antimicrobial effect of photodynamic therapy on halitosis in adolescents through the analysis of volatile sulfur compounds measured using gas chromatography and microbiological analysis of coated tongue.Methods/designA quantitative clinical trial will be carried out involving 60 adolescents randomly divided into the following groups: group 1 will receive treatment with a tongue scraper, group 2 will receive photodynamic therapy applied to the posterior two-thirds of the dorsum of the tongue, and group 3 will receive combined treatment (tongue scraper and photodynamic therapy). Gas chromatography (OralChromaTM) and microbiological analysis will be used for the diagnosis of halitosis at the beginning of the study. Post-treatment evaluations will be conducted at one hour and 24 hours after treatment. The statistical analysis will include the Shapiro-Wilk test for the determination of the distribution of the data. If normal distribution is demonstrated, analysis of variance followed by Tukey's test will be used to compare groups. The Kruskal-Wallis test followed by the Student-Newman-Keuls test will be used for data with non-normal distribution. Either the paired t-test or the Wilcoxon test will be used to compare data before and after treatment, depending on the distribution of the data.DiscussionThe results of this trial will determine the efficacy of using photodynamic therapy alone or in combination with a tongue scraper to treat bad breath in adolescents.Trial registrationThe protocol for this study was registered with Clinical Trials (registration number NCT02007993) on 10 December 2013.
