It has been suggested that "non-celiac wheat sensitivity" is a more appropriate term, without forgetting  that other gluten-containing cereals are implicated in the development of symptoms.NCGS is the most common syndrome of gluten-related disorders with prevalence rates between 0.5%–13% in the general population. As no biomarker for diagnosing this condition is available, its diagnosis is made by exclusion of other gluten-related disorders such as celiac disease and wheat allergy. Many people have not been diagnosed following strict criteria, and there is a "fad component" to the recent rise in popularity of the gluten-free diet, leading to debate surrounding the evidence for this condition and its relationship to celiac disease and irritable bowel syndrome. People with NCGS are often unrecognized by specialists and lack adequate medical care and treatment. They often have a long history of health complaints and unsuccessful consultations with physicians, and thus many resort to a gluten-free diet and a self-diagnosis of gluten sensitivity. Signs and symptoms
Reported symptoms of NCGS are similar to those of celiac disease, with most patients reporting both gastrointestinal and non-gastrointestinal symptoms. In the "classical" presentation of NCGS, gastrointestinal symptoms are similar to those of irritable bowel syndrome, and are also not distinguishable from those of wheat allergy, but there is a different interval between exposure to wheat and onset of symptoms. Wheat allergy has a fast onset (from minutes to hours) after the consumption of food containing wheat and can be anaphylaxic.
Primary
Primary occlusal trauma occurs when greater than normal occlusal forces are placed on teeth, as in the case of parafunctional habits, such as bruxism or various chewing or biting habits, including but not limited to those involving fingernails and pencils or pens. The associated excessive forces can be grouped into three categories. Excesses of:
Duration
Frequency and
MagnitudePrimary occlusal trauma will occur when there is a normal periodontal attachment apparatus and, thus, no periodontal disease. Secondary
Secondary occlusal trauma occurs when normal or excessive occlusal forces are placed on teeth with compromised periodontal attachment, thus contributing harm to an already damaged system. As stated, secondary occlusal trauma occurs when there is a compromised periodontal attachment and, thus, a pre-existing periodontal condition. Cause and treatment
Teeth are constantly subject to both horizontal and vertical occlusal forces. With the center of rotation of the tooth acting as a fulcrum, the surface of bone adjacent to the pressured side of the tooth will undergo resorption and disappear, while the surface of bone adjacent to the tensioned side of the tooth will undergo apposition and increase in volume.In both primary and secondary occlusal trauma, tooth mobility might develop over time, with it occurring earlier and being more prevalent in secondary occlusal trauma. To treat mobility due to primary occlusal trauma, the cause of the trauma must be eliminated. Likewise for teeth subject to secondary occlusal trauma, though these teeth may also require splinting together to the adjacent teeth so as to eliminate their mobility.
