Evaluation Of Fluoride Uptake By Dentine Following Silver Diamine Fluoride Under Resin Modified Glass Ionomer Restoration In Carious Primary Molars

March 4, 2021 updated by: Associate Professor Dr. Rania Abdallah Nasr, Cairo University

Evaluation Of Fluoride Uptake By Dentine Following Pretreatment With Silver Diamine Fluoride And Potassium Iodide Under Resin Modified Glass Ionomer Restoration Versus Resin Modified Glass Ionomer Restoration Alone In Carious Primary Molars: (In Vitro Study)

Dental caries is one of the most common oral diseases of childhood and is considered as a major public health problem especially in areas with poor access to dental care. In a recent cross sectional study carried out in Egypt on 1000 child aged from 3-6 years, it was found that 61.4% of these children had dental caries. In order to avoid serious complications of untreated dental caries such as pain, infections, emergency visits and possibly hospitalization , an effective low cost treatment should be identified particularly in areas with poor dental access.

Studies have proven that silver diamine fluoride (SDF) is a topical fluoride that has the ability to effectively arrest and prevent dental caries.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

It was concluded that fluoride uptake into dentine from conventional GI restorations was not affected in the presence of SDF and KI. It was also mentioned that the results may be different if conditioning is applied not etching and recommended this for future investigation.

Aim: Therefore, the aim of this study is to determine whether carious primary molars treated with SDF and Potassium iodide (KI) prior to placing resin modified glass ionomer (RMGI) restorations will affect the fluoride uptake into primary dentine or not.

Study Setting:

  • The study was conducted in Pediatric Dentistry and Dental Public Health Department Faculty of Dentistry, Cairo University, Egypt.
  • Energy Dispersive X-ray analysis with Scanning Electron Microscope (SEM/EDX) measurement analysis was conducted at the National Research Center (NRC), Egypt.

Freshly extracted discarded primary molars were collected from outpatient clinic of Pediatric Dentistry Department, Faculty of Dentistry, Cairo University at the end of every day.

  • Teeth were then sectioned through the center of the carious lesion mesiodistally using a slow-speed cutting saw with coolant (Isomet 4000, USA) forming two similar halves, so that the 20 molars were sectioned to 40 halves.
  • Each tooth was placed in a separate container with its 2 halves.
  • Teeth containers were then randomly allocated either to the control or intervention group.

Control Group: One half empty and the other half with Resin Modified Glass Ionmer (RMGI) only.

Intervention Group : One half empty and the other half SDF+KI+RMGI

  • After dehydration, teeth were mounted on stubs using double-sided carbon tape, and sputter coated with gold for 20 s using a Turbo molecular pumped coater (QUORUM 150T ES, Laughton, United Kingdom) .
  • Teeth were then placed in SEM/EDX for fluoride measurement by weight percentage.

Data showed parametric distribution so; it was represented by mean and standard deviation (SD) values. Independent and paired t-tests were used for inter and intragroup comparisons respectively. The significance level was set at p ≤0.05 within all tests. Statistical analysis was performed with R statistical analysis software version 4.0.3 for windows (R Core Team, 2020).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study
