Efficacy of conventional treatment with composite resin and atraumatic restorative treatment in posterior primary teeth: study protocol for a randomised controlled trial
Introduction Despite the widespread acceptance of conventional treatment using composite resin in primary teeth , there is limited evidence that this approach is the best option in paediatric clinics .  Atraumatic restorative treatment ( ART ) using high-viscosity glass ionomer cement has gradually become more popular because it performs well in clinical studies , is easy to h and le and is patient friendly . Therefore , the aim of this r and omised clinical trial study is to compare the restoration longevity of conventional treatment using composite resin with that of ART in posterior primary teeth . As secondary outcomes , cost-efficacy and patient self-reported discomfort will also be tested . Methods and analysis Children aged 3–6 years presenting with at least one occlusal and /or occlusal-proximal cavity will be r and omly assigned to one of two groups according to the dental treatment : ART ( experimental group ) or composite resin restoration ( control group ) . The dental treatment will be performed at a dental care trailer located in an educational complex in Barueri/SP , Brazil . The unit of r and omisation will be the child . A sample size of 240 teeth with occlusal cavities and 188 teeth with occlusal-proximal cavities has been calculated . The primary outcome will be restoration longevity , which will be clinical ly assessed after 6 , 12 , 18 and 24 months by two examiners . The duration of the dental treatment and the cost of all material s used will be considered when estimating the cost-efficacy of each treatment . Individual discomfort will be measured after each dental procedure using the Facial Scale of Wong-Baker . Ethics and dissemination This clinical trial was approved by the local ethics committee from the Faculty of Dentistry of the University of São Paulo ( registration no. 1.556.018 ) . Participants will be included after their legal guardians have signed an informed consent form containing detailed information about the research .
