Comparison of a Chemically Activated Composite Resin Alkasite With Resin Composite in Atypical Caries Lesions of Deciduous Teeth - A Non-inferiority Randomized Clinical Trial

Atypical cavities, which involve more than two surfaces, one being buccal or lingual/palatal, are a challenge for restorative dentistry, since the risk of restorative failure is related to the number of surfaces involved. Thus, the purpose of this umbrella project is to conduct a randomized controlled trial (RCT) to evaluate the efficacy and patient-centered outcomes of a chemically activated composite alkasite resin in atypical deciduous molar lesions. Primary molars of children aged 4 to 7 years with at least one atypical cavitary lesion in primary molars will be selected for the RCT. The selected teeth will be randomly divided into: Alkasite chemically activated composite resin and Bulk fill composite resin. Clinical and radiographic follow-up of the lesions will be performed for 6 and 12 months. The effectiveness of the treatments will be evaluated by the longevity of the restorative procedures and paralysis of the lesions. Patient-centered outcomes will also be evaluated.

Selective removal of dental caries with manual instruments, under relative isolation, application of universal adhesive system and restoration with chemically activated composite resin Alkasite.

Selective removal of dental caries with manual instruments, under relative isolation, application of universal adhesive system and restoration with bulk fill resin composite.

For the evaluation of caries progression, the interproximal radiographic examination will be used to verify an increase of radiolucent image under restoration.

Presence of caries lesion on the surface adjacent to the restored tooth or on the margins of the restoration by means of visual Clinical Examination.

To evaluate the satisfaction of the children in relation to the treatment performed. The questionnaire will be used "Child's and parent's questionnaire about teeth appearance".

It will be employed a questionnaire after the completion of the treatment performed. It will also be added a question about the behavior of children during the procedure, which will be categorized as - great behavior, regular or bad.

The parents/guardians will be questioned about the satisfaction regarding the treatment performed in the child. The answer will be scored by a likert scale.

The child will also be questioned as to the discomfort in relation to the treatment performed. For this will be used the scale of faces of Wong-Baker.

The child will also be questioned about the sensitivity of the restorative procedure. For this, the Wong-Baker face scale will be used.

The validated Brazilian version of Early Childhood Oral Health Impact Scale (ECOHIS) will be applied to children and should be answered by their parents.

Inclusion Criteria: Children will be included who have at least one posterior tooth with atypical caries lesion. Exclusion Criteria: Patients with special needs will be excluded, with general health conditions that may affect the oral cavity, non-cooperating in relation to the examination, which use orthodontic apparatus and the parents/guardians or children not to consent to their participation in the study. In addition, teeth with pulp exposure, spontaneous pain, mobility, presence of swelling or fistula close to the tooth, furcation or cervical injury, teeth with restorations, sealants or enamel formation defects will be excluded.
