Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Molar-Incisor Hypomineralization (MIH) is a qualitative enamel defect caused by systemic hypomineralization that affects one to four first permanent molars, and may or may not involve incisors. The clinical repercussions associated with MIH can be characterized by: painful hypersensitivity, post-eruptive fractures, rapid progression of caries lesions in newly erupted first permanent molars, difficulty in achieving effective anesthesia, aesthetic impairments, and patient fear and anxiety. To date, there is no consensus on the best treatment for sensitivity in teeth with MIH, thus managing sensitivity in these teeth remains a significant challenge. The aim of this study is to evaluate the effectiveness of a 10% Biosilicate® solution as a desensitizing agent in MIH teeth in children, compared to Fluoride varnish (Duraphat® Colgate, Brazil). Children aged 6 to 12 years will be selected for this study, with a total of 63 participants diagnosed with MIH, and a sensitivity score ≥2 on the SCASS scale. The children will be randomly divided into two groups (n=21): GI: Duraphat®, GII: Biosilicate®. Interventions will be performed once a week for 4 consecutive weeks, followed by 8 weeks of follow-up. The results will be subjected to statistical tests with a 95% confidence level (α = 0.05).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will evaluate the effectiveness of a 10% Biosilicate® solution as a desensitizing agent in MIH teeth in children, compared to Fluoride varnish (Duraphat® Colgate, Brazil). The children included in the study will be subdivided into three randomized treatment options, which are: Group 1: Fluoridated varnish (Duraphat® Colgate, Brazil); Group 2: Biosilicate® 10%. The randomization sequence will be generated using the envelope method. A numerical sequence (1 and 2) will be printed, which will correspond sequentially to the three groups (GI and GII). The numbers will be placed in envelopes with the same characteristics and then sealed. The implementation of the random allocation sequence will be carried out by a single researcher, who will use the previously sealed envelopes along with the numbers corresponding to the treatments to be administered. As each child is included in the study, an envelope will be labeled with the child's name and will only be opened by the operator before the start of the treatment. Children with the potential for inclusion in the research will be referred for clinical examination in the mobile dental unit (Dental Case), and those with at least one first permanent molar affected by MIH and reporting hypersensitivity, with or without structure loss, will be invited to participate. The complaint of sensitivity will be confirmed by applying a 1-second air blast at a distance of 1 centimeter from the occlusal surface of the tooth; a score of 2 or 3 on the Schiff Cold Air Sensitivity Scale (SCASS) will be considered a positive result.

RANDOMIZED

Intervention Model

PARALLEL

According to the sample calculation of this study, 42 children (21 per group) will be selected, who have teeth with Molar-Incisor Hypomineralization and painful sensitivity in those teeth, recruited from Municipal Schools in Ribeirão Preto, São Paulo, Brazil, and children treated at the Pediatric Dentistry Clinic and the Dental Enamel Clinic of FORP USP. The children included in the study will be subdivided into three randomized treatment options, which are: Group 1: Fluoridated varnish (Duraphat® Colgate, Brazil); Group 2: Biosilicate® 10%. The randomization sequence will be generated using the envelope method. A numerical sequence (1 and 2) will be printed, which will correspond sequentially to the three groups (GI and GII).

Blinding Strategy

TRIPLE

Participants Investigators Outcome Assessors
To ensure the first stage of blinding in the study, the patient will not know which group and type of treatment the tooth will receive. Therefore, we will attempt to standardize some methods to ensure this reliability. The products to be tested will be removed from their original containers and placed in identical 10ml white bottles. The second stage concerns the evaluator. All treatments will be performed by a single operator, and the tests will be applied by another evaluator. In this way, the evaluator will not know the group allocation or the type of intervention that was performed.To increase the reliability of the results, the statistician will also not know the allocation or which groups correspond to each treatment. They will only receive a table with letters representing the groups as A and B and the test values, without knowing which group or interventions were carried out.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Biosilicate® 10%

Supervised tooth brushing will be performed with fluoride-free toothpaste. Then, the tooth affected by MIH will be cleaned with sterile gauze, isolated with a cotton roll, and subsequently, the operator will apply a solution using a microapplicator to all the free surfaces of the selected teeth. This solution will either be a 10% Biosilicate® solution or fluoride varnish (Duraphat®). All products will be removed from their original containers and placed in identical 10ml plastic bottles, white and standardized. The different products will be applied equally for 15 seconds according to the application protocol. Immediately after application, sensitivity tests will be performed using the SCASS and VAS protocols, and will be repeated 1, 2, 4, and 8 weeks after the completion of the treatment. The form for recording the results for each patient is provided in.

Duraphat®

Initially, the child will be instructed not to consume any food or drink for up to 40 minutes after the treatment. Oral hygiene instructions will be given, and a kit with a toothbrush and fluoride toothpaste will be provided. In all groups, the treatment protocols will be applied once a week for 4 consecutive weeks. Supervised tooth brushing will be performed with fluoride-free toothpaste, followed by cleaning the tooth affected by MIH with sterile gauze, isolating it with a cotton roll, and then, the operator will apply a solution to all the free surfaces of the selected teeth using a microapplicator.
