Comparison of clinical retention of fissure sealants with and without using sodium hypochlorite after enamel etching.

Interventions

Intervention 1: Control group: Preparation of permanent mandibular first molar enamel with acid etching (usual method) and use of fissure sealant. Intervention 2: Intervention group: Preparation of en

Eligibility

Sex/Gender

All

Age

7 Years to 12 Years

Inclusion criteria

Inclusion criteria: Participants should have had cooperation and acceptance for dental treatment and good oral hygiene. Patients with a pair of sound first permanent mandibular molars, bilaterally, which were qualified for fissure sealant therapy. Ages between 7 and 12 years. Teeth should have had acceptable situation for isolation with cotton roll and suction.

Exclusion criteria

Exclusion criteria: Presence of any types of dental caries. Medically compromised patients. Tooth isolation impossibility. Lack of cooperation and acceptance from patients or their parents. Self-cleansing occlusal pits and fissures which did not need fissure sealant therapy.

Design outcomes

Primary

Measure	Time frame
The percentage of people in whom fissure sealant retention is increased by the use of sodium hypochlorite. Timepoint: Measurement of fissure sealant retention rate six months after treatment. Method of measurement: After 6 months, all 34 people will be contacted in order of fissure sealant time and in the pediatric ward of the faculty will be checked by 2 pediatric dentists. The reliability of the examiners will be calculated using Cohen's Kappa statistical coefficient. Each fissure sealant will be evaluated independently using a mirror and a slow catheter after 6 months by 2 calibrated researchers, who were not involved in the treatment process. If there is a disagreement between the two researchers during the evaluation period, after discussion, an agreement will be reached. If the treatment fails, the tooth will be re-treated. The examination technique will be visual observation and clinical evaluation.	—
