ABSTRACT
Background: Bruxism is defined as the medical term for clenching and grinding of teeth. It?s one of the most common parafunctional habit, occurring both during sleep "Eccentric Bruxism" and wakefulness "Centric Bruxism". Bruxism can result in tooth wear and damage, jaw disorders, headaches and dental restoration damage. Bruxism is usually a subconscious reflex that is often not recognized by the patient. As a consequence, one of the most difficult aspects of this treatable problem is convincing the patient of this disorder. The early diagnosis and management can prevent the breakdown of the dentition and pain in the orofacial region. Although various treatment modalities are present, the successful management of bruxism lies in the precise diagnosis and isolation of the etiology
Aim of the Study: raw conclusions about the existence of a possible relationship between the two, and its clinical relevance
Study selection: dental literature in bibliographic database like PubMed/Medline was searched for the terms "bruxism? and "prosthetic treatment?, relevant studies were critically reviewed were conducted using, as well as combinations of these and related terms
Results: there is no known treatment to stop bruxism, including prosthetic treatment. The role of bruxism is considered as a major cause in the tooth wear process and as informed by the present critical review, the relationship between bruxism and prosthetic treatment is one that relates mainly to the effect of the former on the latter
Conclusion: Bruxism may be included among the risk factors, and is associated with increased mechanical and/or technical complications in prosthodontic rehabilitation, although it seems not to affect implant survival. When prosthetic intervention is indicated in a patient with bruxism, efforts should be made to reduce the effects of likely heavy occlusal loading on all the components that contribute to prosthetic structural integrity. Failure to do so may indicate earlier failure than is the norm
ABSTRACT
Background: Women have lower bone density than men and they lose bone mass more quickly as they advance in age, which leads to osteoporosis. The Saudi Diabetes and Endocrine Association in the Eastern Province revealed that 30 to 50% of Saudi women above 40 years of age develop osteoporosis. Factors related to the development of osteoporosis include poor diet, low calcium intake, vitamin D deficiency, sedentary lifestyle and smoking. Previous studies have shown that there is a high prevalence of vitamin D deficiency in Saudi women. Methods: The present study was done in 100 Saudi women above 40 years of age who were outpatients in Arar Central Hospital during a period of four months. After taking an informed consent, data was collected relating to the risk factors, vitamin D levels were assessed and the patients underwent a Dual Energy X-ray Absorptiometry (DEXA) scan. Results: The results showed that 82% of Saudi women patients had vitamin D deficiency. Only 21% of women were exposed to sunlight. 58% of the women had low BMD (18% with osteoporosis and 40% with osteopenia). Only 5% of patients took Vitamin D and Calcium rich diet and 7% were in the habit of doing exercise. There was a significant association between bone mass density and exercise when Fisher's exact test was used (P value < 0.05) Conclusion: Prevalence of osteopenia is higher than osteoporosis in the Saudi women above 40 years in the Northern part of Saudi Arabia. The major cause of low BMD is lack of exercise even though there is a high prevalence of Vitamin D deficiency.
