Conservative Versus Non-conservative Treatment for Severe Dental Caries

Status Completed

Clinical Trial Summary

The purpose of this study is to compare the effectiveness of the conservative (pulpectomy) versus non-conservative treatment (tooth extraction) of primary molars affected with severe dental caries associated to oral health-related quality of life, anthropometric and clinical outcomes.

Clinical Trial Description

Treatment: evaluate two interventions for treating severe dental caries in primary molared of preschool children.

SAMPLE: preschool children aged 3 to 5 years with severe dental caries (SDC) in primary molars. SDC will be indicated by the Pufa index. The Pufa index records the presence of severely decayed teeth with visible pulp involvement (p), ulceration of the oral mucosa owing to root fragments (u), fistula (f) and abscess (a). Children with pufa-score > 0 in primary molars will be included in the study. All children aged 3 to 5 years, who sought dental screening at the Dental School, University of São Paulo (USP) in August to October 2013 can be initially eligible.

CLINICAL GROUPS RANDOMLY ASSIGNED:

- Group A: Conservative treatment represented by pulpectomies + teeth restoration with composite resin crown.

- Group B: Dental extraction

- Treatment of carious teeth with pufa score =0 will receive dental fillings (01 occlusal surface affected: ART; 02 surfaces affected: composite resin; ≥ 03 surfaces affected: composite resin crown).

- One operator (specialists in paediatric dentistry) blinded to the outcomes will carry out the treatments.

FOLLOW-UP: 4, 8 and 12 months.

OUTCOMES: All outcomes will be assessed by a single person interviewer/examiner blinded to the oral treatments groups.

1. Oral Health-Related Quality of Life:

- Brazilian SOHO-5

- Brazilian ECOHIS

2. Anthropometric measures:

- Weight-for-age Z-score (WAZ)

- Height-for-age Z-score (HAZ)

- BMI-for age Z-score (BAZ)

3. Dental anxiety (Facial Image Scale).

4. Dental pain (Wong-Baker Scale)

5. Problems in the developing occlusion: loss of space ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
