Public Health DentistryDental plaque is a bacterial biofilm that forms on the teeth and is a common factor in the development of both dental caries and periodontal disease. While fluoride in drinking water can help prevent dental caries, it is not directly related to periodontal disease. Nutritional disturbances can affect the overall health of the individual but are not the sole cause of either
condition. Disturbed occlusion may be a risk factor for certain dental issues but is not universally common to both diseases.

ProsthodonticsExplanation: The combination of acrylic resin posterior teeth
and porcelain anterior teeth can lead to differential wear and stress
concentrations, which may cause resorption of the anterior residual ridge.
Porcelain teeth are harder and can create more stress on the underlying bone
compared to acrylic teeth, leading to potential resorption. Therefore, option 2
is the correct answer, as it highlights the negative impact on the anterior
ridge.

PhysiologyAnswer: 1) DepolarizationExplanation: EPSPs occur when the neurotransmitter binds to postsynaptic receptors that open sodium channels, allowing sodium ions to flow into the neuron and causing the membrane to depolarize. This increases the excitability of the neuron, bringing the membrane potential closer to the threshold for action potential firing.
