🔴 involves the proximal surfaces of anterior teeth but does not include or feature the destruction of the incisal angle.
Rounding or beveling this internal line angle reduces the concentration of stress that could otherwise lead to a fracture of the amalgam at the isthmus. Incorrects: A sharp angle (A) actually increases the risk of fracture.
Incisal edges of anterior or cusp tips of posterior teeth.
: The C-factor is the ratio of bonded to unbonded (free) surfaces in a composite restoration. A Class I cavity has 5 bonded surfaces (pulpal, buccal, lingual, mesial, distal) and only 1 unbonded surface (occlusal), resulting in a C-factor of 5. High C-factors increase polymerization shrinkage stress on the cavity walls. Question 2: Correct Answer is C (Gamma-2 phase) Explanation : The Gamma-2 phase ( operative+dentistry+mcqs+pdf+new
This large collection offers 1000 MCQs specifically focused on operative and endodontic topics. It provides an extensive bank of practice questions for thorough exam preparation. The material can be accessed online in PDF format.

Mastering operative dentistry requires a deep understanding of dental anatomy, material science, and clinical techniques. Multiple-choice questions (MCQs) are the standard format for major dental board exams, including the NBDE, NBDHE, ADC, ORE, and various postgraduate entrance tests. 🔴 involves the proximal surfaces of anterior teeth
Based on recent exam patterns and UHS Model Papers , make sure you have these concepts down cold:
Silver amalgam has high compressive strength but does provide thermal insulation for the tooth. G.V. Black Classification
This report outlines key resources and sample content for recent Operative Dentistry Multiple Choice Questions (MCQs), specifically focusing on materials suitable for 2025–2026 dental board exam preparation. Incisal edges of anterior or cusp tips of posterior teeth
The treatment of choice for a vital, permanent tooth with a wide-open apex and a small traumatic pulp exposure is: A. Pulpectomy B. Apexification C. Apexogenesis D. Indirect pulp capping Answer Key and Explanations
When reviewing these PDFs, prioritize these highly-tested sections:
The keyword is critical. Operative dentistry has evolved dramatically over the last decade. A new PDF should cover:
Critical pH values for enamel (5.5) and dentin (6.2).
In a cavity preparation cavo-surface margin will be junction between: A) Cavity wall/floor and adjacent tooth surface B) Cavity wall and floor C) Floor of occlusal box and approximial box D) Axial wall and occlusal floor
