Efficacy of a Chemically Activated Composite Resin Alkasite in Atypical Caries Lesions of Deciduous Teeth

Efficacy of a Chemically Activated Composite Resin Alkasite in Atypical Caries Lesions of Deciduous Teeth - Randomized Clinical Trial

Atypical cavities, which involve more than two surfaces being one of them vestibular or lingual/palatine, are a challenge for restorative dentistry, since the risk of failure of the restorations are related to the number of surfaces involved. Thus, the objective of this project is to conduct a randomized clinical trial in order to evaluate the efficacy and patient-centered outcomes of a chemically-activated alkasite composite resin in atypical lesions of deciduous molars. Deciduous molars of children between 4 and 7 years of age with at least one atypical cavity lesion in deciduous molars will be selected for the ECR. The selected teeth will be randomly divided into two groups: Chemically activated composite resin Alkasite and resin-Modified glass ionomer cement. Clinical and radiographic follow-up of the lesions will be performed for 6 and 12 months. The efficacy of the treatments will be evaluated by the longevity of the restoring procedures and the arrestment of the caries lesions. Patient-centered outcomes will also be evaluated.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Survival of restoration	To evaluate the survival of restoration by clinical examination with FDI index.	12 months after treatment.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Caries lesion progression	For the evaluation of caries progression, the interproximal radiographic examination will be used to verify an increase of radiolucent image under restoration.	12 months after treatment.
Secondary caries lesion or on the surface adjacent to the restored tooth	Presence of caries lesion on the surface adjacent to the restored tooth or on the margins of the restoration by means of visualClinical Examination	12 months after treatment.
Perception of children and parents/guardians	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".	6 months after treatment.
Operator perception	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.	6 months after the restoration.
Parents/Guardians Satisfaction	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.	6 months after restoration.
Child discomfort	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.	Immediately after the treatment.
Post Operative sensitivity of the child	The child will also be questioned about the sensitivity of the restorative procedure. For this, the Wong-Baker face scale will be used.	7 ° day after the restorative procedure.
Oral health-related quality of life	The validated Brazilian version of Early Childhood Oral Health Impact Scale (ECOHIS) will be applied to children and should be answered by their parents.	6 month of restorative treatment.
