Brief Summary

Minimally invasive dentistry continues to gain importance, especially in the treatment of permanent teeth with deep caries lesions and immature roots. Chemo-mechanical caries removal (CMCR) is an alternative to the conventional method and consists of the application of a proteolytic substance that softens carious dentin tissue and facilitates its removal using manual instruments. This method can be employed without the use of local anesthesia or burs, thereby preserving sound dental tissue. The trial aim to assess the clinical performance of Brix 3ooo and Papacarie duo gel as chemo-mechanical caries removal agents (CMCR), their performance in terms of time required for the caries removal, patient subjective pain reaction, their radiographic success and their antimicrobial effect in comparison with Atraumatic Restorative Treatment (ART) hand excavation method for caries removal. The trial will include 108 children with age ranging between 8 and 10 years old who have at least one carious first permanent molar will be randomly divided into three groups. A three-arm randomized clinical trial where test groups, group I, caries removal will be using Brix 3000, and group II Papacarie duo will be used, while the control group hand excavation will be the method of caries removal. Dentin samples of three groups will be taken prior to and following caries removal. The total viable streptococci and lactobacilli count will be determined and expressed as colony forming units per milliliter (CFU). The time required for caries removal with each method will be calculated and the subjective pain reaction following each method will be recorded. After complete caries removal step, it will be followed by restoration with glass ionomer restoration. Patients will be followed up at 3-, 6- and 12-month intervals to determine the clinical success and at 6- and 12- month intervals for the radiographic success rate for each caries removal method.

Outcome Measures

Primary Outcomes (2)

  • To assess and compare the efficacy of two chemo-mechanical agents Brix 3000 and Papacarie duo in terms of their clinical success in young permanent molars, in comparison with hand excavation approach

    The clinical assessment will be at 3-, 6- and 12-month intervals to evaluate restoration success according to the criteria of atraumatic restorative treatment by Phantumvanit et al. (1996) .Restorations which will receive a score of 0, 1 or 7 will be considered successful while those having a score of 2, 3, 4 or 8 will be considered failures. Those which will receive a score of 5, 6 will be excluded from the analysis.

    one year follow up

  • To assess and compare the efficacy of two chemo-mechanical agents Brix 3000 and Papacarie duo in terms of their radiographic success in young permanent molars, in comparison with hand excavation approach

    The radiographic evaluation will be performed using the radiographic subtraction method

    one year follow up

Secondary Outcomes (3)
