Intra oral digital x ray
In dentistry two major types of x rays used to film the mouth - intra oral x-rays and extra oral x rays. Intra oral x-rays involve placing the x-ray film inside the mouth and extra oral x-rays place the x-ray film outside the mouth. The amount of radiation is reduced by around 80% using this technique. These x-rays allow the dentist to identify dental problems that cannot be identified with the naked eyes. Intra oral digital xrays help the dentist take a close look at the tooth roots, study the condition of the developing tooth, scrutinize general tooth health, identify caries and check the strength of the bony region adjoining the tooth.
Various types of intra oral x-rays are bite-wing x-rays, periapical x-rays and occlusal x-rays. X-ray films are substituted with electronic pad or sensors and the pictures are filmed. The x-rays fall on the pad in a similar fashion as they fall on the film and the pad or sensor transfers the image directly to the computer and a print out is taken unlike developing the x-ray film in a dark room. The main benefit of these x-rays is that they help comparison of current images to previous images without any difficulty and over the computer itself.
Xerostomia or Dry Mouth is a condition that can occur due to many reasons. It is often indicative of other health conditions. There is reduced saliva flow, not necessarily due to decreased salivary gland function. Other conditions that occur with xerostomia include constant sore throat, dry nasal passage, burning mouth or difficulty in swallowing. Symptoms of xerostomia include thick saliva, cracked lips and sores at the mouth corners. There might be red patches on the tongue and palate. The tongue appears dry with very few papillae - indentations. Xerostomia can lead to reduced oral pH and increased risk of plaque and dental caries, if left untreated. Other conditions that can develop include tongue ulcers, oral candidiasis, halitosis and sialadenitis.
Oral cavity examination to measure the flow rate of saliva is done to diagnose xerostomia. This is done through sialometry test. Sialography is an imaging test wherein the salivary glands are examined for stones and masses. The patients medications must be examined. Medications are the main cause for xerostomia. These include antihistamines, antidepressants, anti-Parkinson agents, diuretics and sedatives. Analgesics, decongestants and muscle relaxants also cause this. Another cause for xerostomia is Sjogren's syndrome. Other causes include sarcoidosis, rheumatoid arthritis, systemic lupus erythematosus, scleroderma, diabetes mellitus, hypertension, cystic fibrosis, endocrine disorders and amyloidosis.
Palliative methods include use of water and glycerin and avoidance of alcohol-based mouth washes. Sip plenty of plain cool water. Eat more blended and moist foods. Include hard cheese in the diet. Suck on sugar-free gum. Artificial saliva and salivary stimulants might be suggested by the physician. Pilocarpine is the most prescribed medication for xerostomia.
A dentist dedicated to the dental and oral health of children is a pediatric dentist. In other words, pediatric dentists are pediatricians of dentistry. A pediatric dentist attends to the dental problems of infants' right through the teenage years. A pediatric dentist requires additional qualification after a graduation in general dentistry to meet the special needs of children. Visiting a pediatric dentist from early childhood to the growing years can help avoid dental treatments at later age and stage.
