Indications for the use of a removable partial denture include:
1) Large edentulous space, deep undercut of abutment, not posterior of
abutment.
2) Periodontitis of abutment, aesthetic concerns for posterior teeth, not
posterior of abutment.
3) Deep undercut of abutment, periodontitis of abutment, not posterior of
abutment.
4) Large edentulous space, not posterior of abutment, periodontitis of
abutment
Prosthodontics Answer: 4
A removable partial denture is indicated in cases of large edentulous spaces, especially when there is periodontitis affecting the abutment teeth, as it can help restore function and aesthetics.
Actinobacillus actinomycetam comitans is commonly associated with
1) Juvenile periodontitis
2) Adult periodontitis
3) Refractory periodontitis
4) All of the above
Periodontics
Answer: 4
False about anodontia
1) May involve both the deciduous and the permanent dentition
2) In false anodontia tooth does not undergo full development
3) May involve a single tooth
4) In total anodontia all teeth are missing
Oral Pathology
Answer: 2
Usually full mouth survey of radiographs for edentulous patients is done to
1. Detect any residual root tips retained
2. Detect supernumerary teeth
3. To detect periapical infections
4. To detect the presence of cysts and tumours
Endodontics
Answer: 1
Apically positioned flap is placed
1. 1 mm corona to crest of alveolar bone
2. 2 mm apical to crest of alveolar bone
3. At crest of alveolar bone
4. 5 mm coronal to crest of alveolar bone

Answer: 2
What are the main components of a typical dental composite resin?
1) Monomers, fillers, initiators, and accelerators.
2) Resins, fillers, catalysts, and diluents.
3) Polymers, pigments, and plasticizers.
4) Monomers, fillers, and cross-linking agents.
Dental composite resins typically consist of a resin matrix (monomers), filler particles (such as silica or glass), initiators (like camphorquinone), and accelerators (such as amines) to control the setting process.
