Properties of Glass Ionomer Cements Associated With Chlorhexidine or Doxycycline

Biological and Physicomechanical Properties of Glass Ionomer Cements Associated With Chlorhexidine or Doxycycline

This study assessed the clinical performance of a resin-modified glass ionomer cement containing different concentrations of chlorhexidine digluconate and doxycycline hyclate.

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.

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.
