PedodonticsThe Russell periodontal index does not indicate masticatory efficiency.

RadiologyRadiographic detection of carious lesions or dentinal destruction typically requires a certain threshold of loss of tooth structure. Studies have shown that a loss of approximately 40 microns of dentin is necessary for a radiograph to show evidence of carious lesions.

ProsthodonticsThe lingual extension of the mandibular impression should be tested by functional movements of the tongue.

ProsthodonticsCross Arch Stabilization: RPDs provide cross arch stabilization by distributing the forces of mastication more evenly across the remaining natural teeth and the edentulous (toothless) regions of the arches. This is particularly beneficial when there are missing teeth on both sides of the mouth. An RPD connects to the teeth on both sides of the mouth, which helps maintain the alignment and stability of the remaining dentition. In contrast, a fixed bridge typically relies on the adjacent natural teeth for support, which can result in increased load and stress on these abutment teeth. This additional stress can potentially lead to issues such as tooth decay, root fracture, or periodontal disease if not managed properly.

ProsthodonticsRetromolar area should be covered in CD or distal extension RPD in order to derive support from the underlying bone which is resistant to resorption.

ProsthodonticsThe pattern of mandibular movement of complete denture patients and those with natural teeth are the same.

Oral MedicineNeurofibromatosis type 1 is an autosomal dominant disorder caused by a mutation in the NF1 gene, which produces neurofibromin. The gene is located on chromosome 17.

Oral SurgeryNasal fractures, even minor ones, can lead to bruising (ecchymosis) and
swelling (edema) around the nose and face due to the vascularity of the area.
Most nasal fractures, especially minor ones, do not require reduction
(surgical realignment) unless there is significant displacement or functional
impairment. Typically, if reduction is necessary, it is done shortly after the
injury, not for a few weeks.
Traumatic telecanthus (increased distance between the inner canthi of the
eyes) can occur with severe nasal injuries, but it is not a necessary
complication of all nasal fractures.
Severe nasal fractures can lead to complications such as the telescoping of
the nasal complex, which may involve displacement into adjacent structures,
including the frontal sinus.
