The goal of the project is to investigate the clinical efficacy of management of early caries lesions by resin infiltration and to further scrutinize the patient stress experiences.
The aim of this study is to test the clinical efficacy of caries infiltration to arrest proximal caries lesions in primary molars. It was hypothesized that infiltrated lesions (test lesions) will progress significantly less than non infiltrated lesions (control lesions). Additionally, it was hypothesized that dental anxiety and stress related to caries infiltration will be significantly less than dental anxiety related to a conventional restorative procedure. The study will be a controlled clinical trial with a split mouth design and blind evaluation of the outcome (caries progression). Caries progression will be evaluated annually, 12, 24, and 36 months after treatment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Resin infiltration | Experimental | This study is a split mouth design. One tooth with a proximal caries lesion is randomized into this arm and another tooth to the arm "Control". Teeth in this arm are treated by the resin infiltration technique using Icon (DMG, Germany) according to manufactures´ instructions. In addition patients and their guardians are instructed to floss once a day and to brush with fluoridated toothpaste twice a day. Digital bitewing radiographs will be taken at baseline and repeated after 12 months. Additionally caries risk will be evaluated. |

| Control | Other | This study is a split mouth design. One tooth with a proximal caries lesion is randomized into this arm and another tooth to the arm "Resin infiltration". Teeth randomized into this arm do not recieve any special treatment except general oral nonivasiv treatment (flossing and brushing). Patients and their guardians are instructed to floss once a day and to brush with fluoridated toothpaste twice a day. Digital bitewing radiographs will be taken at baseline and repeated after 12 months. Additionally caries risk will be evaluated. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Resin infiltration | Device | Proximal caries lesions that are selected for this intervention will be treated with the resin infiltrant Icon according to the manufacturer's instructions. In short, local anesthesia of the gingival papila, application of rubber dam, etching of the lesion surface for 120 s using 15%HCl gel, washing the lesion with water spray for 30 s, drying the lesion with 100% ethanol for 30 s and subsequent air blowing, application of the infiltrant for 180 s using an applicator provided with the kit, removing excess material from the lesion surface by air blowing and flossing, light curing of the infiltrant for 40 s, repeated application for 60 s, light curing for 40 s, polishing, and removal of the rubber dam. |
| Measure | Description | Time Frame |
|---|---|---|
| Caries progression rate | Radiographic evaluation of infiltrated and control caries lesions to evaluate caries progression. This is done by pairwise comparison of digital bitewing radiographs by one calibrated, blinded examiner. | 1 year |
| Measure | Description | Time Frame |
|---|---|---|
| Stress reaction during treatment | To evaluate dental anxiety and stress reactions in relation to the caries infiltration procedure in comparison with a dental examination appointment and conventional resin restoration appointment. A facial image scale with five faces ranging from very happy (1) to very unhappy (5) will be used. | Immediate |

| Control | Device | Proximal caries lesions do not recieve a placebo treatment, but simply left untreated. |
|
| Caries risk |
Caries risk is asses based on caries index (Nyvad criteria), proximal plaque index (0 = no visible plaque; 1 = visible plaque) and gingival bleeding index (0 = no bleeding after flossing; 1 = bleeding after flossing), dietary habits, and exposition to fluorides based on the Cariogram model. |
| Baseline, 6 months, 1 year, 2 years, 3 years |
| Caries progression rate | Radiographic evaluation of infiltrated and control caries lesions to evaluate caries progression in long term. This is done by pairwise comparison of digital bitewing radiographs by one calibrated, blinded examiner. | 2 years, 3 years |
