The main purpose of choosing the topic was to research the relationship between osteoporosis and periodontal diseases. Osteoporosis is a bone disease that causes a decrease in the strength and density of bones, which ultimately leads to weak bones prone to fragility. Bones become weak and spongy and are prone to fracture even with minor injury. Periodontal disease is a condition that affects the gum tissues and bones that support the teeth. Periodontal disease is caused by a bacterial infection of the teeth causing inflammation of the gums. Types of periodontal disease include gingivitis and periodontitis. Gingivitis is characterized by red, swollen and easily bleeding gums caused by poor oral hygiene. Periodontitis is advanced gingivitis that lasts a long time without treatment. It is caused by a buildup of plaque on the surface of the teeth that spreads to the surface of the gums. Bacterial plaque releases toxins that cause gum irritation and tooth pain (Bollen, 2006). Type of osteoporosis and periodontal disease. The type of osteoporosis includes primary osteoporosis type 1 or postmenopausal and secondary osteoporosis. Type 1 occurs in women over 75 after menopause, while secondary osteoporosis can occur at any age, mainly due to prolonged use of certain medications that compress calcium in the bones or a deficiency in calcium in the body. Normal bones contain calcium, collagen and proteins that strengthen bones. Normal bones are strong and do not break easily unless there is a serious injury. A normal bone fracture can occur when the bone is under stress, while in an osteoporotic patient, a bone fracture occurs with minimal stress during normal activity, especially when...... middle of paper. ..... accompanied by symptoms such as oral discomfort, burning sensation and progression of periodontal disease. During my research, I encountered difficulties in researching the relationship between osteoporosis and periodontal disease because some information was unclear. The study of the relationship between the two diseases is still ongoing and most experiments are carried out on rats and not humans. However, the research was successful and the results obtained proved that there is a correlation between periodontal disease and osteoporosis, both being associated with loss of bone mass density. In conclusion, further studies are needed in researching the relationship between the two diseases and people should be informed about the potential causes of osteoporosis, which are potential contributing factors leading to periodontal disease (Megason, 2010).
