Myositis ossificans would NOT cause pathologic fractures of maxilla or mandible because it involves ossification within muscle tissue, not weakening of existing bone structure. Bone cysts, multiple myeloma, and giant cell tumor all cause bone destruction and weakening, predisposing to pathologic fractures. Myositis ossificans actually adds calcified tissue rather than destroying bone.

In a double-blind study, neither the participants nor the experimenters know who is receiving the treatment or the placebo. This is to prevent any bias in the study results due to the expectations of the participants or the researchers. The statement that the investigator can omit data that fails to support the hypothesis is not correct; data should be analyzed as is to maintain the integrity of the study.

Fluorosis is associated with osteosclerosis, not osteoporosis. It leads to increased bone density due to excessive deposition of fluoride.

Group 2 (Cleidocranial dysplasia, achondroplasia, craniofacial dysostosis) is characterized by relative/absolute mandibular prognathism. These conditions involve maxillary hypoplasia or underdevelopment, creating relative mandibular prognathism. Group 1 conditions (Treacher Collins, Pierre-Robin, Leontiasis ossea) are not typically associated with mandibular prognathism - Pierre-Robin has micrognathia, and Treacher Collins has mandibular hypoplasia.

Stimulation of the cholinergic system can lead to increased penile erection due to the vasodilation of blood vessels in the penis, allowing for greater blood flow and engorgement of the corpora cavernosa.
