Initiate a calcium hydroxide pulpectomy Initiate conventional root canal treatment with gutta-percha Place calcium hydroxide on the pinpoint exposure Open the pulp chamber to find healthy pulp tissue and perform a pulpotomy 14. Preventive resin restoration is used In non accessible proximal areas In cavitated pit and fissure sealants In deep caries Used in non cavitated pit and fissure sealants 15. Which of the following are advantages a light cured materials over chemical cure sealants? All of the above Less chance of incorporation of air bubble Working time is longer Better physical and mechanical properties 16.
