Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Anterior primary teeth with class V caries in children aged 4-7 years, who screen in the Department of Pediatric Dentistry at Damascus university, will be involved in this split mouth design study
Intra- and extraoral examinations of patients will be performed before the treatment and their initial radiologic examinations will be performed.
The carious lesion will be covered with Enzyme Pepsin-based Gel and left undisturbed for 40 s. Then, it will be removed by scraping gently with a spoon excavator without application of any vertical pressure, under the isolation of rubber dam, this process will be repeated until the cavity appeare clean. caries detector dye will be used to confirm that the cavity is free of caries.
All teeth will be restored with Glass inomer cement.
The expected duration for the whole procedure is 20 minutes
A single practitioner will perform excavation of caries for all teeth so that caries removal and excavation will be identical.
Clinical and radiographic evaluation will be performed after 3 and 6 Months.
Intervention code [1] 320559 0
Treatment: Other
Comparator / control treatment
Carisolv solution will be used to remove caries in the control side.
The carious lesion will be covered with Carisolv solution and left undisturbed for 30 s. Then, it will be removed by scraping gently with a spoon excavator without application of any vertical pressure, under the isolation of rubber dam, this process will be repeated until the cavity appeare clean. caries detector dye will be used to confirm that the cavity is free of caries.
All teeth will be restored with Glass inomer cement.
The same practitioner will perform excavation of caries for all control teeth so that caries removal and excavation will be identical.
Clinical and radiographic evaluation will be performed after 3 and 6 Months.
Control group
Active

Outcomes
Primary outcome [1] 327518 0
Efficacy of Enzyme pepsin-based gel and Carisolv solution as a chemomechanical caries removal agent in primary teeth will be assessed clinically by another observer who did not know the treatment method, using Visual and tactile assessment by manual probing, and using a caries detector.
Timepoint [1] 327518 0
(T1): Immediately following caries removal
Secondary outcome [1] 395496 0
Evaluation of pain using Wong-Baker FACES pain rating scale
Timepoint [1] 395496 0
(T1): During caries removal
Secondary outcome [2] 395497 0
The need for anesthesia
In the presence of pain during the procedure, the Wong-Baker FACES pain rating scale would be used and when the score was greater than or equal to 3, local anesthesia would be administrated,
the need for the administration of anesthesia was based on the evaluation of the procedure, patient behavior, and the cause of the pain.
Timepoint [2] 395497 0
(T1): For the duration of the procedure,
Secondary outcome [3] 395498 0
Evaluation of caries relapse radiologically
Caries recurrence will be evaluated using periapical radiographs by another researcher without informing him of the method of removing caries, so he will evaluate the presence or absence of caries recurrence.
Timepoint [3] 395498 0
(T1): 3 months after treatment
(T2): 6 months after treatment
Secondary outcome [4] 401716 0
Evaluation of caries relapse clinically
The clinical examination will be conducted by the researcher in the absence of diagnostic cards in order to avoid knowing the type of treatment applied using a caries detector.
Timepoint [4] 401716 0
(T1): 3 months after treatment
(T2): 6 months after treatment
Secondary outcome [5] 401717 0
Evaluation of pulp vitality clinically
The clinical examination will be conducted by the researcher in the absence of diagnostic cards in order to avoid knowing the type of treatment applied through the absence of symptoms and clinical signs indicating pulp necrosis.
Timepoint [5] 401717 0
(T1): 3 months after treatment
(T2): 6 months after treatment
Secondary outcome [6] 401719 0
Evaluation of pulp vitality radiologically
Pulp vitality will be evaluated using periapical radiographs by another researcher without informing him of the method of removing caries through the absence of radiographic signs indicating pulp necrosis.
Timepoint [6] 401719 0
(T1): 3 months after treatment
(T2): 6 months after treatment
Secondary outcome [7] 401720 0
The number of materials application times
The number of both materials application times will be counted by the investigator from the start of caries removal till confirm the cavity is free of caries by caries detector dye.
Timepoint [7] 401720 0
During caries removal

Efficacy
Statistical methods / analysis
Sample size was calculate using g-power 3.1 software. The significance level was set at 0.05 and the power of the study was set to be 0.80.
Based on a Chi – Square test, it was estimate that 40patients were required to demonstrate an effect size (0.4).
Sample size will be raised to 46patients to avoid the negative effect of the possible drop rate.
Statistical analyses will be performed using the statistical software SPSS for Windows (version 25.0, SPSS Inc.,Chicago,IL,USA).

The chi-square and McNemar test will be performed. A P value <0.05 will be considered statistically significant.
