Defective connective tissue leads to fragile capillaries, resulting in abnormal bleeding, bruising, and internal hemorrhaging. Collagen is an important part of bone, so bone formation is also affected. Teeth loosen, bones break more easily, and once-healed breaks may recur. [8] Defective collagen fibrillogenesis impairs wound healing.
As its biological causes have been more precisely determined, it has become more widely recognized that while the primary disease process of OI happens in the bones, the most common types of OI—those caused by type I collagen gene mutations—affect virtually all of the human body's organs in some way.
The condition is associated with sailors who weren't eating fruit and vegetables — but it's more common than you'd think.
Scurvy, caused by a deficiency of vitamin C which is necessary for the synthesis of collagen. Fibromuscular dysplasia is a disease of the blood vessels that leads to an abnormal growth in the arterial wall.
The type II and XI collagenopathies are a group of disorders that affect connective tissue, the tissue that supports the body's joints and organs. These disorders are caused by defects in type II or type XI collagen. Collagens are complex molecules that provide structure, strength, and elasticity to connective tissue.
1: Total loss of attachment (clinical attachment loss, CAL) is the sum of 2: Gingival recession, and 3: Probing depth. Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth.

Collagen disease is a term previously used to describe systemic autoimmune diseases (e.g., rheumatoid arthritis, systemic lupus erythematosus, and systemic sclerosis), but now is thought to be more appropriate for diseases associated with defects in collagen, which is a component of the connective tissue.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
