Randomized Clinical Trial of Fissure Sealants Comparing Universal Adhesive With Etch-And-Rinse Adhesive After 24 Month

April 7, 2021 updated by: Dr Emel Karaman, Ondokuz Mayıs University
Objective: This randomized, controlled clinical study aimed to evaluate the performance of one universal adhesive applied with etch-and-rinse or self-etch strategy and one etch-and-rinse adhesive on fissure sealant retention over 24 months. Methodology: 144 sealants were placed on the permanent premolars and molars of 13 subjects. Teeth were divided into three groups SB2(control): Adper Single Bond 2, SBU-ER: Single Bond Universal/etch-and-rinse, SBU-SE: Single Bond Universal/self-etch. After the adhesive application, Fissurit FX was applied and light-cured. Clinical evaluations were done at baseline and at 1 week, 6-, 12-, 18- and 24-month recalls. Visual examination was performed on every visit for evaluation of the sealants. Evaluating criteria were: 1= completely retained; 2= partial loss; 3= total loss. The Pearson Chi-square test was used for each evaluation period.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Thirteen patients with a mean age of 20.5 (range 19-22) were selected among the patients seeking routine dental care from Conservative Dentistry Department who met the inclusion criteria. Inclusion criteria were: good oral hygiene and and the absence of caries, previously placed restorations, bruxism and an allergy to the materials tested.

Bitewing radiographs were taken. Pellicle and any remaining plaque on the fissures were removed by using slurry of pumice with a slow-speed handpiece. All restorative procedures were performed by the same operator. The teeth were assigned for different group by using a table of random numbers.

Group 1 (SB2): Etched with 35% phosphoric acid gel for 30 s, rinsed and dried. Adper Single Bond 2 (3M ESPE St. Paul MN. USA) applied and light cured for 10s with a LED device (Demi Plus; Kerr, Switzerland) Group 2 (SBU-ER) : Etched with 35% phosphoric acid gel for 30s, rinsed and dried. Single Bond Universal Adhesive (3M ESPE St. Paul MN.USA) applied, gently air thinned for 5 s and light cured for 10s with a LED device Group 3 (SBU-SE): Single Bond Universal Adhesive (3M ESPE St. Paul MN.USA) applied for 20 s with vigorous agitation, gently air thinned for 5 s and light cured for 10 s with a LED device A nanofilled fissure sealant, Fissurit FX (Voco,Cuxhaven,Germany) was applied to the fissures and air entrapment was prevented by carefull spreading with a dental probe. The sealant material was light-cured for 20 seconds with LED. The occlusion was checked with articulating paper. Fine-grit diamond burs (Diatech, Swiss Dental, Switzerland) and rubber cups (Edenta AG, AU SG, Switzerland). were used for finishing and polishing.

Each restoration was evaluated at baseline,1week after treatment and 6, 12, 18 and 24 months. Evaluation of restorations was carried out by two calibrated examiners who were unaware of group allocation and who were not involved with the treatment procedures, by the help of a mirror, blunt explorer and air stream. Caries formation was evaluated as present or absent and the sealants were evaluated according to the following criteria: 1= Completely retained 2= Partial loss 3= Total loss.

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.
