Long-term granular diet may lead to declined resistance to trauma of the temporomandibular joint.

This study was carried out to determine the effect of food texture on the response to trauma of the temporomandibular joint in mice. Animals were fed either a solid or granular diet after weaning. At 8 weeks old, condylar hypermobility was induced by forcing the mouth wide open ten times under ether anaesthesia.

Lack of the bone remodeling in osteopetrotic (op/op) mice associated with microdontia.

Osteopetrosis is an inherited metabolic disease characterized by an excessive accumulation of bone. This is associated with an osteoclast deficiency. Osteopetrosis is always accompanied by the failure and/or delay of tooth eruption.
