About this study

This study aimed to evaluate the in vivo microbiologic action of the best concentration of chlorhexidine and doxycycline associated with the resin-modified glass ionomer cement applied on remaining dentine after indirect pulp treatment.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • an active deep carious lesion at the internal half of the dentine thickness of a primary molar that had not been previously restored and that involved the occlusal or occlusoproximal surface;
  • the absence of signs of irreversible damage to the pulp
  • the absence of radiolucencies at the interradicular or periapical region or thickening of the periodontal spaces, absence of internal and external root resorption, absence of calcification of the pulp tissue
  • children presenting no systemic disease or those not using medications.

Exclusion criteria

  • presence of signs of irreversible damage to the pulp
  • children presenting systemic disease or those using medications.

Treatment and study plan

Indirect pulp treatment

Other

Carious dentine was sampled from the mesial portion of the cavity floor and the pulpal wall was entirely covered with one of the randomly selected materials: GIC containing 4.5% DOX; GIC containing 1.25% CHX or GIC as a control group. The antimicrobial concentrations were chosen based in the previous in vitro results obtained in this study. The cavities were then temporarily restored using a conventional GIC. Within 3 months after the initial treatment,the materials were carefully and completely removed, a new dentine sample was collected, and the teeth were then restored with a light-cured composite resin using a bonding system, after a new placement of the initial liner material.

Primary outcomes

  1. Indirect Pulp Treatment using GIC associated with 1.25% CHX or 4.5% DOX.

    Time frame: up to 3 months

    Within 3 months after the initial treatment, the teeth were submitted to clinical and radiographic examination to determine signs and symptoms of pulp vitality.

Secondary outcomes

  1. Indirect Pulp Treatment using GIC associated with 1.25% CHX or 4.5% DOX.

    Time frame: up to 3 months

    Dentine samples were collected at baseline and after 3 months of the treatment for microbiological evaluation (colony-forming unit - CFU).
