Brief Summary

To assess the influence of the choice of fluoride varnish flavor on the acceptance and cooperation in schoolchildren between (5-10) years during the dental visit, in which an application of fluoride varnish is indicated.

Detailed Description

The main assumption of the study is giving the child the option to choose e.g. their preferred taste of the fluoride varnish possibly moves the focus away from not being willing to receive the fluoride varnish application to rather accepting it (pseudoalternative).

The aim of this study is to investigate the impact of participation via choosing the taste of the fluoride varnish (locus of control and pseudo-alternative) on the acceptance and cooperation during dental visit in schoolchildren aged 5 to 10 years.

This two-parallel arm single-blind randomized controlled clinical trial will be undertaken at the Department of Preventive and Pediatric Dentistry at the University of Greifswald from approximately January 2022 to Autumn 2022. The child will be randomly allocated using simple random sampling with the use of random table method, in which 35 randomly generated serial numbers for each group will be generated by Windows Microsoft Excel (2010, USA) to ensure equal randomization of each group.

The test group will receive a previously allocated flavor of fluoride varnish (Profluorid VOCO, Germany) ranging from (Melon, Caramel, Cherry, Bubble gum, Mint) containing 22,500 ppm fluoride. However the test group will be receiving the choosing the taste of the previously mentioned fluoride varnish r with flavor ranging from (Melon, Caramel, Cherry, Bubble gum, Mint). After allocation an independent observer enters the dental treatment room for blinded assessment. After the dental visit, the participating child, the accompanying parent or caregiver, the dental operator and the blinded assessor receive a short questionnaire to be filled out.

Patients presenting with acute pain or with signs and symptoms, which should be treated will not be asked to participate. Moreover Systemic diseases that require special attention during their dental treatment or Parents/children who refused to participate in the study, and reported allergy against ingredients of the toothpaste are excluded from participation.

Assessment would be done firstly by observing participants' behavior and then categorized using the Frankl's behavior rating scale-FRS (Frankl, 1962) by an independent blinded observer, and the accompanying parent.

Secondly, The dental anxiety level of the child using the facial image scale (FIS) consists of a row of five gray scale faces ranging from very happy to very unhappy, moreover a questionnaire will be filled out by the caregivers (including questions on demographic issues) on their acceptance and preference regarding the choice of the taste of the fluoride varnish.

Further data of the child for better description of the baseline characteristics of the participants will be taken from the documentation in the patient's file: e.g. age, sex, dmft / DMFT, history of dental anxiety, history of invasive dental treatment e.g. nitrous oxide sedation or dental general anesthesia.

Intervention Type: BEHAVIORAL

For the test group, before the standard check-up starts, the participant is given the choice of selecting the taste of the fluoride varnish (Profluorid VOCO, Germany) from a range of about five flavors (Melon, Caramel, Cherry, Bubble gum, Mint), which will be applied at the end of the visit. Post-placement instructions provided by the manufacturer will be given to the caregiver and the child and questionnaires will be handed out.
