None of the above', 'role': 'user'}, {'content': 'Answer: D \nExplanation: A\xa0few\xa0reports\xa0of\xa0adverse\xa0effects\xa0have\xa0been\xa0attributed\xa0to hybrid ionomers, which release HEMA, a monomer that can\xa0cause\xa0 pulpal\xa0 inflammation\xa0and\xa0allergic\xa0contact\xa0dermatitis. Therefore, hybrid ionomers are not as biocompatible as conventional\xa0glass\xa0ionomers.\xa0Dental\xa0personnel\xa0may\xa0be\xa0at\xa0risk from\xa0adverse\xa0effects\xa0such\xa0as\xa0contact\xa0dermatitis\xa0and\xa0other immunological responses. The temperature increase associated with the polymerization process can also be considered as a drawback of hybrid ionomer cements.\nRef: Phillip’s Science of Dental Materials ed 12 pg 327', 'role': 'assistant'}]
