UHS PGET Periodontology MCQs with Answers: Sample Questions & Preparation

The UHS Postgraduate Entrance Test (PGET) in Lahore is the written gate to MD, MS, MDS and FCPS induction. It has two papers of 100 single-best-answer MCQs, two hours each: Paper I basic medical sciences and Paper II the specialty. This page is for BDS graduates aiming for MDS Periodontology and shows a sample of Periodontology questions with answers and one-line explanations.

What Periodontology practice covers

The Periodontology bank covers gingival and periodontal disease, classification and therapy, alongside the Paper I BDS basic-sciences core. Questions come from FCPS Part 1 and SZABMU Part-I collections plus reviewed recall material, and each keeps a source tag.

Sample MCQs

1. Aortic regurgitation is not seen in

• A) Ankylosing spondylitis
• B) Bacterial endocarditis
• C) Acute myocardial infarction ✅
• D) Marfan's syndrome

• B) 2nd premolar
• C) lateral incisor
• D) canine

Width of attached gingival is greatest in the incinor region ( maxilla 3:5 to 4.5 mm mandible 3.3 to 3.9mm)and least width is in the first premolar region ( maxilla 1.9 mandible 1.8mm)

3. Which of the following is true:

• B) External resorption appears contiguouswith the canal on X-ray examination.
• C) The apexiocator accurately differentiate between internal and external resorption.
• D) Internal resorption is larger in size thanthe external resorption

Internal resorption is contiguous with the canal

4. Which of the following drugs is/are used in the treatment of radiation xerostomia?

• A) Bethanechol
• B) Pilocarpine
• C) Anetholetrithione
• D) All of the above ✅

Xerostomia is one of the common complications of radiotherapy. Sialagogues are used to stimulate salivary secretion. Pilocarpine is best-studied sialagogue. Others are anetholetrithione, bethanechol and bromhexine.

5. The 18/8 stainless steel used in orthodontic wire contains —

• A) 18% iron: 8% nickel
• B) 18% nickel: 8% chromium
• C) 18% chromium: 8% nickel ✅
• D) 18% chromium: 8% cobalt
• E) 18% nickel: 8% cobalt

18/8 stainless steel is 18% chromium and 8% nickel.

6. The main advantage of composites over unfilled direct filling resin is their:

• A) Higher solubility in saliva
• B) Lower modulus of elasticity
• C) Esthetic excellence
• D) Lower thermal co-efficient of expansion ✅

Advantages of composites (filled resins) over unfilled resins are lower co-efficient of thermal expansion, low polymerization shrinkage, low water absorption and high abrasive resistance.

How to use these questions
