Calcium Hydroxide, Mineral Trioxide Aggregate and Biodentine (Trademark) as Direct Pulp Capping of Permanent Teeth

Phase 2

Completed

Interventions: Drug: Calcium hydroxide
Drug: Mineral trioxide aggregate
Drug: Biodentine

Brief Summary: Background: Dental caries is considered an oral health problem worldwide. In Chile the last national epidemiological study (2007) showed a national prevalence of dental caries in children 6 years (70.3%) and 12 (62.5%). Direct pulp capping is a preventive dental therapy, keeps the vitality of the tooth using some inductive materials mineralized tissue formation.

Objective: The main objective of this study is to evaluate the effectiveness of two innovative direct pulp capping materials; Biodentine compared MTA and calcium hydroxide in the maintenance of pulp vitality in teeth permanent molars.

Detailed Description: Methodology: It is a randomized controlled study. groups signed the informed consent for clinical trial patients, a clinical evaluation of 90 permanent molars teeth through endodontic diagnostic tests and radiograph. will be conducted to determine diagnosis. Will be assigned randomly to the type of material to use and direct pulp teeth affected by caries coating is carried out; Patients will not have knowledge of the material to be used in the coating. The patient will be clinically evaluated at 1 week, 3 months and 8 months, and radiographically; at the beginning and end of the study. In each clinical control endodontic diagnostic tests of heat, cold, electric and percussion will be performed. In radiographic controls take a radiograph control with positioner or surveyor at baseline and 8 months, to evaluate the periapical status. Clinical success will consider that tooth in continuous controls and after 8 months presented vitality and radiographic signs of apical image without injury. Failure unresponsive to consider whether susceptibility testing of cold and electricity in more than one control and presents radiographic image with apical lesion.

Recruitment & Eligibility

Inclusion Criteria

Teeth that have pulp exposure not exceeding 1 mm in size.

Exclusion Criteria

Every child with systemic and / or neurological conditions that make it impossible to focus on conventional dental clinic
