Active clinical trials for "Dental Caries"

Dental caries is highly prevalent across the globe including Pakistan and is associated with tooth loss, malocclusion and temporomandibular joint problems and sometimes may cause life threatening infections. Streptococcus mutans is considered to be one of the major pathogen responsible for the development of dental caries. As treatment of dental carries is quite expensive, main focus is on the prevention of dental carries. Chlorhexidine is the gold standard mouthwash used for the prevention of dental carries but its use has been associated with certain side effects including staining of teeth, burning sensation and a bitter taste in the oral cavity. Many populations use medicinal plants as traditional or alternative treatments for various ailments due to their better safety profiles, health beneficial effects, lower cost and easy availability. Among the plant species used for medicinal purposes are those of the genus Morus. Its most commonly used species are Morus alba, rubra and nigra that have also shown antimicrobial properties against various infections in addition to other health promoting effects. Moreover, morus alba fruit has not been evaluated for its antimicrobial activity against oral pathogens including streptococcus mutans. The purpose of this study is to evaluate the antimicrobial properties against salivary streptococcus mutans and alteration of pH in the saliva of patients with dental caries before and after the use of chlorhexidine and morus alba fruit extract mouthwashes. This study is double blinded randomised clinical trial. Sample size is calculated according to open Epi calculator and came out as 1 in each group. We will take sample size as 120 and the sampling technique will be non-probability consecutive sampling. Morus alba extract preparation will be done in the Botany department of Lasbella University of Agriculture, Water and Marine Sciences (LUAWMS) Balochistan. According to inclusion criteria and after obtaining informed consents, samples of saliva of the individuals of 18-40 year of both genders will be collected from the OPD of Dentistry department, Civil hospital Uthal Balochistan at the beginning of the study and two weeks after the treatments. The total 120 subjects will be equally divided into three groups, 40 participants in each group (A, B and C). The subjects in group A will be given chlorhexidine mouthwash and the subjects in group B and C will be given 20% and 30% aqueous extracts of morus alba fruit in the form of mouthwashes respectively. The samples of saliva will be analysed for S.mutans counts and pH levels at baseline and 15 days after the use of respective mouthwash. Culture procedure for S.mutans count will be Dilution and Spread plate technique.

The literature recognizes that fluoride is the most widely used and studied means for dental remineralization. The use of fluoride mouthwashes is shown as an effective way to increase the fluoride intraoral availability. However, the current challenge is the substantivity, so new compounds have been introduced into these formulations. This study aims to evaluate the in vivo effect of fluoride mouthwash containing nanoencapsulated Fluoride (NanoF) - in fluoride retention in saliva and dental plaque. A study of the clinical and laboratory type, crossover, double-blind, randomized will be held. After sample calculation, the total of 12 individuals aged between 18 and 35 years old, healthy, decayed, missing, and filled teeth index less than 6 and residents in brazilian northeast capital will be part of the sample. Fluoride bioavailability will be evaluated in the biofilm and saliva after the use of fluoridated weekly. The biofilm will be assessed on 1h and 12 h after rinsing; and unstimulated saliva in times of 3, 15, 30, 45, 60 minutes and 12 hours after. It will be 3 mouthwashes: 50% Nanoencapsulated Fluoride, 100% Nanoencapsulated Fluoride and Free sodium fluoride. Between weeks of use, rinsing will be extended washout (without fluoride) to avoid carryover effect. Inferential data analysis will be carried out, considering the amount of alpha <0.05. So knowing that caries is a dynamic process, the largest fluoride retention in the oral fluids promoted by the Nanoencapsulated Fluoride may have important impact on Des-Re process and in the control of dental caries.

The focus of the study is to evaluate the safety of multiple study drug administrations and the study drug selectively reducing or eliminating a specific bacteria in the mouth. It will compare a liquid and gel product applied in different modes.

To evaluate the effect of daily ingestion of the probiotic Lactobacillus reuteri on the levels of secretory IgA and the cytokines Il1-beta, IL-6, IL-8 and IL-10 in saliva of healthy young adults.

The aim of the prospective project is to investigate effect of daily probiotic supplements on dental caries development in preschool children living in a low socioeconomic immigrant area in souithern Sweden. The study design is a randomised controlled trial with two parallell arms. The intervention is one probiotic tablet or placebo once daily. The null hypothesis is that the caries experience and increment will not differ betwwen the two groups.

The aim of the present investigation was to evaluate the effect of stevioside and rebaudioside on several variables related to caries development. Two approaches were performed: an in vitro evaluation of the growth of a culture of mutans streptococci and in vivo randomized study on the effect of a single rinse containing stevioside and rebaudioside on plaque-pH.

The proposed test is intended to enable dentists to differentiate between cavitated and non-cavitated tooth decay in the areas where teeth are in contact (interproximal surfaces). In these areas, dentists cannot visually inspect for caries, and currently bitewing X-rays (BWs) only correctly detect the presence of enamel decay 15-25% of the time. This low sensitivity can lead to late treatment resulting in unnecessarily large fillings, crowns, pain, root canals, and possible later loss of teeth. Hypothesis: Use of radiographic contrast on teeth will increase the accuracy of detection of early cavitation from 58% to 90%.

Objective: The aim of this study is to assess the effectiveness of an oral health educative intervention in preventing early childhood caries (ECC). Methods: The trial targets 0- to 12-month-old children and their mothers in Pelotas, Brazil. Twenty-four public health centres (clusters) were randomly selected and assigned to intervention or control group (12 clusters per intervention group). In each center, up to 30 children/mothers were selected and invited to participate in the trial. Each mother was interviewed in order to collect socio-economic and demographic variables. The intervention group received by means of a pamphlet the oral health instructions, which were emphasized with verbal instructions. Dental examination will be carried out after 1 year for all teeth surfaces to determine caries status.

The purpose of this study is to determine if adding daily application of CPP-ACP containing paste for one year is superior to regular fluoride tooth brushing in preventing dental caries in high caries risk Thai preschool children.

Dental caries is the most common chronic disease of childhood and is increasing in prevalence in children 2-5 years old. Racial and ethnic minority groups as well as economically disadvantaged individuals are affected the most by this health outcome. This study will test if a community-based multimodal intervention will reduce 2-year incidence of early childhood caries (ECC) in children aged 0-5 living in public housing developments. The intervention combines the components of motivational interviewing (counseling) delivered by dental health advocates, fluoride varnish application, oral health assessment and referral. The investigators hypothesize that the multimodal intervention with motivational interviewing will reduce ECC behavioral risk factors thereby leading to a reduction of ECC incidence when compared to fluoride varnish application, written oral health education materials and oral health assessment and referral.
