Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All cases diagnosed with primary lower 2nd molars class 2 caries will undergo inferior alveolar nerve block as regional anesthesia using topical benzocaine gel 20% and 2% lidocaine with 1/80000 adrenaline (Septodent) injected through 25 mm gauge 27 disposable needle (NEDTC). A rubber dam will be applied and mesial or distal class II cavity preparation will be performed followed by application of metal cervical matrix band with wooden wedges. Then total etching using 39% phosphoric acid and Futurabond™, (VOCO) is applied. The preparations will be distributed in a randomized way to be filled with one of the following materials: Dental bulk fill composite X-tra fill™, (VOCO)(Intervention arm 1) , Polyacid-modified resin composite Glasiosite Compomer™, (VOCO)(Intervention arm 2), and a resin composite applied by incremental technique Polofil Supra™, (VOCO)(Control arm). These preparations will be performed using a turbine handpiece (NSK) and diamond round and cutting burs in addition to composite finishing burs. The procedure lasts for 30 minutes in average.
As all the procedures for all recruited cases are performed by single dentist (the principal investigator) who perform all three kinds of procedures with adherence to protocol proposed by himself. Also, photos are available for most cases in different stages of procedures.
The children will be followed up 3, 6, and 12 months later for outcome evaluation.
Clinical evaluation, procedures and follow up visits will be done in pediatric dentistry department in Damascus University on outpatient basis by a different dentist who is pediatric dentistry undergraduate with 3 years pediatric dentistry experience.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Number are allocated to the expected recruited cases from the beginning. These number are randomly allocated to three groups. When the case is recruited it will be previously allocated to one of the groups with no intervention awareness by the investigator who recruited it.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomization using a randomization table created by www.graphpad.com.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Efficacy
Statistical methods / analysis
Sample size was calculated using g-power 3.1 software. The significance level set at 0.05 and the power of the study at 0.80.
Based on a one-way Anova test, it is estimated that 60 patients needed to demonstrate an effective size.
SPSS statistical software for Windows will be used for statistical analysis.
Kruskal Wallis test will be applied. Deviations from the baseline will be tested for significance with the Wilcoxon Signed Rank Matched Paris Test.
Interrater reliability will be tested using Cohen Kappa measure,
The level of significance will be set at 0.05.
