Effectiveness of Two Health Education Interventions in the Prevention of Caries and Gingivitis in Orthodontic Patients

March 15, 2025 updated by: Adriana del Pilar Forero, Universidad Nacional de Colombia

Effectiveness of Motivational Interviewing and Conventional Oral Health Education (OHEc) Versus OHEc in the Prevention and Control of Dental Caries and Gingivitis in Subjects With Fixed Orthodontic Appliances. A Randomized Controlled Trial

Dental caries and gingivitis are classified by the World Health Organization (WHO) as an important public health problem due to their high prevalence and incidence worldwide despite the development of public policies to combat them. They are chronic diseases that have a severe impact in terms of pain and suffering, impairment of function and effect on quality of life. During orthodontic treatments, the most common adverse event is the appearance of dental caries lesions and gingivitis due to increased retention and change of dental biofilm composition or difficulty of removal with conventional oral hygiene techniques. Efforts to implement various conventional preventive interventions of self-care and education have not decreased their incidence, so it is necessary to implement motivational interventions to help adolescents and young adults to make positive changes in their oral health habits, which are constant and lasting and prevent and control gingivitis and 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

Dental caries and gingivitis are multifactorial diseases, however the only necessary factor, although insufficient for their development, is bacterial biofilm; brackets significantly increase its retention and limit self- cleaning mechanisms, representing a challenge in clinical practice. Motivational interventions in oral health could be an alternative to generate behavioral changes in oral health and daily self-care routines that are more sustainable over time compared to conventional education models in patients with fixed orthodontic appliances. A randomized controlled clinical trial open to subjects and single-blinded (investigators) of parallel groups is proposed for the evaluation of the effect of motivational interviewing combined with conventional oral health education (OHEc) versus OHEc, in the prevention of dental caries lesions and gingivitis. A sample size of 94 patients in total is proposed, distributed 47 in each arm of the study, with a follow-up of the cohort for six months. The baseline risk will be established before the placement of fixed appliances (T0), and a follow-up will be carried out during six months, with assessments in one (T1), three(T2) and six months (T3) after cementation, where the presence of gingivitis, caries and changes in risk variables, adverse events and adherence to conventional and motivational interventions, will be measured.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Conventional Oral health Education
Conventional oral health education and nutritional guidelines prior to the placement of fixed appliances, by means of a 5-8 minute video and instructive brochure.
Other: Conventional Educational interventions
Conventional educational methods can be verbal, written or visual and can be combined for greater understanding and effectiveness in oral health and dietary routines. The education are imparted in the first appointment of the appliances cementation by a video and oral health instruction booklet and each patient receive an oral hygiene kit. This education is repeated in month 1 and 3 after appliances cementation.
Experimental: Motivational interviewing + Conventional Oral health Education
Include the conventional oral health education of the control group and a 30 minute motivational interviewing (MI)
Other: Conventional Educational interventions
Conventional educational methods can be verbal, written or visual and can be combined for greater understanding and effectiveness in oral health and dietary routines. The education are imparted in the first appointment of the appliances cementation by a video and oral health instruction booklet and each patient receive an oral hygiene kit. This education is repeated in month 1 and 3 after appliances cementation.
Behavioral: Motivational intervention
In addition to the conventional educational method, a motivational interviewing (MI) by Miller and Rollnick of 30 minutes will be used, with an initial script according to the stage of change in each patient in T0. The reinforcements of motivational interviewing are in month one and three after the installation of the braces, they will have the same methodology but will be focused on the aspects that in the previous session or in the clinical assessment were detected as the most important deficiencies or risk factors for the patient.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures
