Which of the following is not a mouth temperature except Korrecta type I.
Which of the following is not true regarding the muscular influence on
denture borders
1. Masseter muscle may influence the borders and flange of the maxillary denture
2. Temporal muscle may influence the denture flange in the maxillary tuberosity
area
3. Medial pterygoid muscle may influence the denture border in the region of the
pterygomaxillary notch
4. None of the above
Prosthodontics
Answer: 3
Explanation: The medial pterygoid muscle primarily functions to move the
mandible medially and assist in closing the jaw. It does not directly influence
the borders of a maxillary denture in the region of the pterygomaxillary notch.
Instead, it is involved in the movement of the mandible and may indirectly
affect the fit and stability of the denture.
Of the three dimensions of colour, the one which describes the dominant colour of the object is
1. Hue
2. Value
3. Chroma
4. Maverick
Prosthodontics
Answer: 1
Hue refers to the attribute of a color that allows it to be classified as red, blue, green, etc. It is one of the three dimensions of color, along with value (lightness) and chroma (intensity or saturation).
The occlusal plane for the complete denture patient is determined by
1. The face bow device which determines the occlusal plane
2. The position of the upper first molar
3. The height of the retromolar pad and anterior aesthetic height
4. None of the above
The occlusal plane for the complete denture patient is determined by the height of the retromolar pad and anterior aesthetic height.
Which of the following materials have maximum osseous integration
1) Tantalum and titanium
2) Vitreous carbon
3) Porous aluminium silicate
4) Alumina and sapphire
Prosthodontics
Answer: 1
Maximum osseous integration is a term used in the context of dental implants and refers to the degree to which the bone tissue of the jaw integrates with the implant material. Tantalum and titanium are both biocompatible materials that are known for their excellent osseointegration properties. Titanium is the most commonly used material for dental implants due to its high biocompatibility and strong osseointegration. Tantalum is also biocompatible, but it is not as commonly used as titanium.
An acrylic substitute for the loss of soft tissue in soft palate is called
1) Obturator
2) Artificial velum
3) Mould
4) Model
Prosthodontics
Answer: 2
An artificial velum is a prosthetic device used to replace lost soft tissue in the soft palate, which is crucial for functions such as speech and swallowing. It helps in closing the gap between the oral cavity and the nasal cavity, thereby improving the function of the palate.

3. 18.12 cm square
4. 20.25 cm square
Prosthodontics
Answer: 1
The mean denture bearing area in the edentulous mandible is approximately 12.25 cm square.
Main advantage of RPD over fixed bridge in replacing bilateral lost teeth
1) Cross arch stabilisation
2) Aesthetics
3) Less expensive
4) Comfort of the patient
Prosthodontics
Answer: 1
Cross Arch Stabilization: RPDs provide cross arch stabilization by distributing the forces of mastication more evenly across the remaining natural teeth and the edentulous (toothless) regions of the arches. This is particularly beneficial when there are missing teeth on both sides of the mouth. An RPD connects to the teeth on both sides of the mouth, which helps maintain the alignment and stability of the remaining dentition. In contrast, a fixed bridge typically relies on the adjacent natural teeth for support, which can result in increased load and stress on these abutment teeth. This additional stress can potentially lead to issues such as tooth decay, root fracture, or periodontal disease if not managed properly.
