In a person with Parkinsons disease, there is insufficient dopamine and motor symptoms such as tremors, rigidity, problems with counterpoise and bradykinesia can occur. According to the National Parkinson Foundation, four to six million people worldwide are estimated to confuse Parkinsons Disease. In the United States alone, the incidence is estimated at fifty to sixty thousand new cases diagnosed each year. Additionally, the Center for Disease Control puts complications from Parkinsons disease as the 14th leading cause of death. composition there is no cure, the symptoms can be controlled with medications and surgery. 6 A 2011 German cross sectional study revealed that people with Parkinsons Disease had poorer oral health. They were found to have more caries, tooth mobility, gingival recession and periodontic pocket ing than the control cohort. Additionally, the group with Parkinsons disease reported less frequent tooth brushing and dental visits, and exhibited reduced salivary flow. 4. Supporting this, a separate Japanese study showed more untreated caries and deeper periodontal pockets, leading to fewer natural teeth in persons with Parkinsons Disease 2. There is a significant population with Parkinsons Disease, a condition that has been shown to have a negative impact on oral health. increase caries and periodontal problems can lead to tooth loss and edentulism, a condition treatable with traditional or implant retained overdentures.Patient RM is a male with Parkinsons disease. He is partially edentulous with six maxillary teeth and two mandibular teeth. ... ...100.2 Hanaoka A, Kashihara K.
