Which of the following muscles has two separate functions in mandibular
movement
1) Masseter
2) Geniohyoid
3) External(lateral)pterygoid
4) Buccinator
Anatomy Answer: 3
The external (lateral) pterygoid muscle has two primary functions: it assists in depressing the mandible (opening the mouth) and in moving the mandible forward (protrusion). This dual function distinguishes it from other muscles of mastication, which primarily elevate the mandible.
High heat obturation technique refers to
1) Thermofill technique
2) Ultrafill technique
3) Sectional filling
4) Obtura II technique
Endodontics
Answer: 4
Obtura II is a high heat obturation technique used in endodontics (root canal treatment) to fill and seal the root canal system of teeth. This technique involves the use of a thermoplasticized gutta-percha, which is heated to a high temperature and then compacted into the root canal with a heat source such as a heated plugger or a heated tip of a handpiece. The heat helps to soften the gutta-percha, allowing it to adapt to the irregularities of the root canal system and form a tight seal against bacterial microleakage. Thermofill and Ultrafill are not high heat techniques, while sectional filling is a method of filling the canal in increments, which may or may not involve heat.
The prognosis of the broken instrument in root canal is good when
1) Instrument is less than 20 No.
2) Instrument is lodged in the bone beyond the apical area
3) Instrument obliterates apical third of the canal
4) Instrument is in middle
Endodontics
Answer: 3
Which of the following structures is most likely to be damaged when per forming flap surgery on the complete mandibular arch?
1. Mental nerve
2. Attachment of mylohyoid muscle
3. Retromolar pad
4. Attachment of buccinator muscle
Periodontics
Answer: 1
The mental nerve is situated beneath the mandibular arch and is at risk during
flap procedures, especially when flaps are elevated or repositioned in that
area.

2) The incidence of the disease was more in those consuming zarda pan
3) The disease can be cured if Zarda pan is stopped
4) None of the above
