Effectiveness of Fissure Sealant in Preventing Caries in Yemeni Children

Objective: To evaluate the effectiveness of the Fisseal (ProMedica, Germany) in Yemeni school children. Children that selected for the current study were between 5-12 years old. Methods: Eighty five patients who required fissure sealant for deep pits and fissure on 38 premolars teeth and 47 molars teeth was recruited. Clinical and radiographic examinations were demonstrated to select the children that are needed for fissure sealant. The treatment and recall protocol was approved by the ethical committee from the Faculty of Dentistry. The patient's informed consent was obtained before enrolment in the clinical evaluation. Initially, the rubber dam was applied to isolate the teeth. The enamel surface of the pit and fissure was then cleaned. After that, teeth for each patient were dried with air. Each tooth surface was then etched by phosphoric acid for 30-60 seconds. Afterwards, tooth surface was rinsed for 10 seconds with an air water spray. Each tooth then dried with air. After that, Fisseal (ProMedica, Germany) was applied to tooth pits and fissures and then light-cured for 40 seconds. The patients were then recalled at 1, 3, 6 and 9 months by clinical investigation. Results: The survival rate for Fisseal (ProMedica, Germany) was 98.82%, with follow up months varying from 1 to 9 months. Conclusions: Pits and fissures were occluded successfully by utilizing Fisseal (ProMedica, Germany). No any colour change was shown in interfacial of treated teeth and sealant materials.
