Conservative DentistryExplanation: In a Class V amalgam restoration, the occlusal wall (or the wall facing the occlusal surface) is typically wider than the gingival wall (the wall facing the gingiva). This design feature helps to provide adequate bulk for the restoration, ensuring strength and resistance to fracture. The other options, such as retention undercuts and wall convergence, are not characteristic features of Class V restorations, which are primarily concerned with the gingival and occlusal relationships.

It is also used to treat ventricular tachycardia and to perform nerve blocks Dosage Of Local Anesthesia: 1) Safety dose of 2% Lignocaine is 4.5mg/kg without a Vasoconstrictor Without a Vasoconstrictor 300 mg (maximum dose) 2) Safety dose of 2% Lignocaine is 7mg/kg with a Vasoconstrictor With a Vasoconstrictor – 500 mg (maximum dose) 3) As 1ml of 2% Lignocaine contains 20mg – Where the Maximum safety dose being 300 mg So 15 ml of Drug can be given safely 4) 1:1,00,000 concentration means 1 part of Adrenaline is 1,00,000 parts of Solution Safety Dose of Adrenaline for Dental Use in normal patients is 0.2 mg – which means 20 ml of LA can be given to normal patients containing Adrenaline For cardiac Patients the safety dose of Adrenaline is 0.04mg – Which means 4ml of LA can be given to Patients with cardiac problems containing Adrenaline 5) If the concentration of LA is 1:50,000 – 10 ml of LA can be given safely

Retaining the primary second molar is often the most conservative approach when the permanent successor is congenitally missing, provided the primary molar has a good root structure and is functional. Minimal proximal stripping can help
manage space and alignment

PeriodonticsThe location of calculus (subgingival vs. supragingival) influences the choice of instrument type (e.g., hand scalers vs. ultrasonic scalers). The area of the mouth (anterior vs. posterior) also affects instrument selection due to accessibility and angulation. The depth of pockets is crucial as deeper pockets may require specific instruments designed for subgingival scaling.
