Conservative Dentistry Answer: 1

In case of a deep caries lesion incomplete debridement is done to
1) Allow secondary dentin formation first
2) To seal the cavity and create aseptic field
3) Prevent pulp exposure and allow a thin layer of a dentin to remain
4) Avoid microleakage

Conservative Dentistry Answer: 3

Mercuroscopic expansion in dental amalgam occurs when
1) Moisture contamination occurs during condensation of zinc containing amalgam
2) Moisture contamination occurs during truturation of zinc containing amalgam
3) Mercury released as a result of electrochemical corrosion re-reacts with Ag-Sn particle
4) Mercury released as a result of electrochemical corrosion re-reacts with Ag-Cu particle

Conservative Dentistry Answer: 3
