EndodonticsThe most common consequence of bleaching non-vital teeth is cervical resorption. This occurs because: 1) Bleaching agents can penetrate through dentinal tubules and reach the cervical area, 2) The agents cause chemical irritation to periodontal ligament cells, 3) This triggers inflammatory resorption at the cervical region, 4) The process can be progressive and lead to tooth loss. Proper isolation with cervical seal using glass ionomer cement helps prevent this complication.

ProsthodonticsNon-rigid or semi-rigid connectors are used in dental bridges when there is a need to accommodate non-parallel abutments (option 2). This design allows for some movement between the components of the bridge, which can help in achieving a better fit and function when the abutments are not parallel.

Conservative DentistryExplanation: When dealing with adjacent Class III cavities, it is generally recommended to prepare the larger cavity first and fill it last. This approach allows the dentist to have better access and visibility when preparing the larger cavity, which can be more complex. Filling the larger cavity last helps to avoid contamination and ensures that the smaller cavity can be filled with precision without compromising the integrity of the larger restoration.
