  • Guideline # 18 ORAL HEALTH
    Guideline # 18 ORAL HEALTH RATIONALE Dental caries, commonly referred to as “tooth decay” or “cavities,” is the most prevalent chronic health problem of children in California, and the largest single unmet health need afflicting children in the United States. A 2006 statewide oral health needs assessment of California kindergarten and third grade children conducted by the Dental Health Foundation (now called the Center for Oral Health) found that 54 percent of kindergartners and 71 percent of third graders had experienced dental caries, and that 28 percent and 29 percent, respectively, had untreated caries. Dental caries can affect children’s growth, lead to malocclusion, exacerbate certain systemic diseases, and result in significant pain and potentially life-threatening infections. Caries can impact a child’s speech development, learning ability (attention deficit due to pain), school attendance, social development, and self-esteem as well.1 Multiple studies have consistently shown that children with low socioeconomic status (SES) are at increased risk for dental caries.2,3,4 Child Health Disability and Prevention (CHDP) Program children are classified as low socioeconomic status and are likely at high risk for caries. With regular professional dental care and daily homecare, most oral disease is preventable. Almost one-half of the low-income population does not obtain regular dental care at least annually.5 California children covered by Medicaid (Medi-Cal), ages 1-20, rank 41 out of all 50 states and the District of Columbia in receiving any preventive dental service in FY2011.6 Dental examinations, oral prophylaxis, professional topical fluoride applications, and restorative treatment can help maintain oral health.

  • Tooth Decay Information
    ToothMasters Information on Tooth Decay Definition: Tooth decay is the destruction of the enamel (outer surface) of a tooth. Tooth decay is also known as dental cavities or dental caries. Decay is caused by bacteria that collect on tooth enamel. The bacteria live in a sticky, white film called plaque (pronounced PLAK). Bacteria obtain their food from sugar and starch in a person's diet. When they eat those foods, the bacteria create an acid that attacks tooth enamel and causes decay. Tooth decay is the second most common health problem after the common cold (see common cold entry). By some estimates, more than 90 percent of people in the United States have at least one cavity; about 75 percent of people get their first cavity by the age of five. Description: Anyone can get tooth decay. However, children and the elderly are the two groups at highest risk. Other high-risk groups include people who eat a lot of starch and sugary foods; people who live in areas without fluoridated water (water with fluoride added to it); and people who already have other tooth problems. Tooth decay is also often a problem in young babies. If a baby is given a bottle containing a sweet liquid before going to bed, or if parents soak the baby's pacifier in sugar, honey, or another sweet substance, bacteria may grow on the baby's teeth and cause tooth decay. Causes: Tooth decay occurs when three factors are present: bacteria, sugar, and a weak tooth surface. The sugar often comes from sweet foods such as sugar or honey.

Joint pain preceded diagnosis by up to three years in five patients and 15 years in one patient. Joints most commonly involved were lumbar spine, hips, and knees (four cases). In three cases there were no bowel symptoms. All were seronegative. X-rays were abnormal in two cases. HLA-type Al, B8, DR3 was present in five and B27 in two patients. Circulating immune complexes showed no consistent pattern before or after treatment. Coeliac disease was diagnosed in all patients by jejunal biopsy, and joint symptoms in all responded to a gluten-free diet. Gluten challenge (for up to three weeks) failed to provoke arthritis in three patients tested. In a separate study of 160 treated coeliac patients attending regular follow up no arthritis attributable to coeliac disease and no ankylosing was in a group spondylitis identified, though control of 100 patients with Crohn's disease thecopyright. expected incidence of seronegative polyarthritis (23%) and ankylosing spondylitis (5%) was found (p<0.01).

  • Conditions Related to Inflammatory Arthritis
    Conditions Related to Inflammatory Arthritis There are many conditions related to inflammatory arthritis. Some exhibit symptoms similar to those of inflammatory arthritis, some are autoimmune disorders that result from inflammatory arthritis, and some occur in conjunction with inflammatory arthritis. Related conditions are listed for information purposes only. • Adhesive capsulitis – also known as “frozen shoulder,” the connective tissue surrounding the joint becomes stiff and inflamed causing extreme pain and greatly restricting movement. • Adult onset Still’s disease – a form of arthritis characterized by high spiking fevers and a salmon- colored rash. Still’s disease is more common in children. • Caplan’s syndrome – an inflammation and scarring of the lungs in people with rheumatoid arthritis who have exposure to coal dust, as in a mine. • Celiac disease – an autoimmune disorder of the small intestine that causes malabsorption of nutrients and can eventually cause osteopenia or osteoporosis. • Dermatomyositis – a connective tissue disease characterized by inflammation of the muscles and the skin. The condition is believed to be caused either by viral infection or an autoimmune reaction. • Diabetic finger sclerosis – a complication of diabetes, causing a hardening of the skin and connective tissue in the fingers, thus causing stiffness. • Duchenne muscular dystrophy – one of the most prevalent types of muscular dystrophy, characterized by rapid muscle degeneration. • Dupuytren’s contracture – an abnormal thickening of tissues in the palm and fingers that can cause the fingers to curl. • Eosinophilic fasciitis (Shulman’s syndrome) – a condition in which the muscle tissue underneath the skin becomes swollen and thick. People with eosinophilic fasciitis have a buildup of eosinophils—a type of white blood cell—in the affected tissue.

  • Third Molar (Wisdom) Teeth
    Third molar (wisdom) teeth This information leaflet is for patients who may need to have their third molar (wisdom) teeth removed. It explains why they may need to be removed, what is involved and any risks or complications that there may be. Please take the opportunity to read this leaflet before seeing the surgeon for consultation. The surgeon will explain what treatment is required for you and how these issues may affect you. They will also answer any of your questions. What are wisdom teeth? Third molar (wisdom) teeth are the last teeth to erupt into the mouth. People will normally develop four wisdom teeth: two on each side of the mouth, one on the bottom jaw and one on the top jaw. These would normally erupt between the ages of 18-24 years. Some people can develop less than four wisdom teeth and, occasionally, others can develop more than four. A wisdom tooth can fail to erupt properly into the mouth and can become stuck, either under the gum, or as it pushes through the gum – this is referred to as an impacted wisdom tooth. Sometimes the wisdom tooth will not become impacted and will erupt and function normally. Both impacted and non-impacted wisdom teeth can cause problems for people. Some of these problems can cause symptoms such as pain & swelling, however other wisdom teeth may have no symptoms at all but will still cause problems in the mouth. People often develop problems soon after their wisdom teeth erupt but others may not cause problems until later on in life.

  • Joint Pain and Sjögren’S Syndrome
    Joint Pain and Sjögren’s Syndrome Alan N. Baer, MD, FACP Alan N. Baer, MD, FACP Associate Professor of Medicine Division of Rheumatology Johns Hopkins University School of Medicine Director, Jerome Greene Sjogren's Syndrome Clinic 5200 Eastern Avenue Mason F. Lord Bldg. Center Tower Suite 4100, Room 413 Baltimore MD 21224 Phone (410) 550-1887 Fax (410) 550-6255 In 1930, Henrik Sjögren, a Swedish ophthalmologist, examined a woman with rheumatoid arthritis who had extreme dryness of her eyes and mouth and filamentary keratitis, an eye condition related to her lack of tears (1). He became fascinated by this unusual debilitating condition and subsequently evaluated 18 additional women with the same combination of findings. He described this new syndrome as “keratoconjunctivitis sicca” in his postdoctoral thesis. Thirteen of the 19 women had chronic inflammatory arthritis. We would now classify these 13 women as having secondary Sjögren’s syndrome (SS), occurring in the context of rheumatoid arthritis. However, joint pain constitutes one of the most common symptoms of the primary form of SS, defined as SS occurring in the absence of an underlying rheumatic disease. In a recent survey of SS patients belonging to the French Sjögren’s Syndrome Society (Association Française du Gougerot-Sjögren et des Syndromes Secs), 81% reported significant joint and muscle pain (2). In this article, the joint manifestations of primary SS will be reviewed. A few definitions are needed for the reader. Although the term “arthritis” was originally applied to conditions causing joint inflammation, it now includes disorders in which the joint has become damaged by degenerative, metabolic, or traumatic processes.
