Study Notes

Applegate's Classification is a system used to categorize edentulous (toothless) arches in preparation for denture construction. The classification is based on the amount and quality of the remaining alveolar ridge, the relationship of the ridge to the residual ridges, and the presence of undercuts. The system is primarily used in the context of complete denture prosthodontics to determine the best approach for achieving retention, stability, and suppo…

Berkson's Bias is a type of selection bias that occurs in case-control studies, particularly when the cases and controls are selected from a hospital or clinical setting. It arises when the selection of cases (individuals with the disease) and controls (individuals without the disease) is influenced by the presence of other conditions or factors, leading to a distortion in the association between exposure and outcome. Key Features of Berkson'…

Innervation of the Skin Innervation of the skin is mainly through the three branches of the trigeminal nerve (CN V). Some skin over the angle of the mandible and anterior and posterior of the auricle is supplied by the great auricular nerve from the cervical plexus. Some cutaneous branches of the auricular branch of the facial nerve also supplies skin on both sides of the auricle. The trigeminal nerve is the general sensory nerve to the head, part…
