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

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.


Pediatric dentist

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.


  • A pediatric dentist handles normal children as well as hospitalized, handicapped and chronically ill children. The pediatric dentist can approach the child's own special needs in a sensitive, caring and professional manner. A pediatric dentist employs medication and controls pain to alleviate the child's apprehension about treatment.
  • Prevention of dental diseases and disorders is a pediatric dentist's primary concern. A pediatric dentist advises parents that regular dental care should begin by one year of age. A pediatric dentist explains and discusses diseases of the gum, and how to avoid or minimize the damage if it has already started in the child.
  • Preventive home care for brushing, flossing, diet control programs, importance of the use of fluorides are taught by a pediatric dentist.
  • The issue of 'nursing decay', often called 'bottle mouth syndrome' is bound to occur in infants. As the name indicates, this is a pattern of decay associated with prolonged nursing. A pediatric dentist recommends that a child be weaned by approximately twelve months of age to prevent such nursing caries.
  • It is normal for a pediatric dentist to prevent tooth decay by using sealants. A sealant is a clear or shaded plastic material that a pediatric dentist uses to apply to the chewing surfaces of the back teeth. In a child, the back teeth have depressions and grooves on their chewing surfaces and so it is difficult and sometimes impossible to clean. The sealant forms a coating or barrier to protect the tooth from bacteria and bits of food. A pediatric dentist helps dramatically reduce the risk of decay for children and teens by protecting such depressions and grooves with a coating of sealant.
  • Bite problems (malocclusion) are often a concern of parents of young children. Sometimes this problem is hereditary when a child has an extra or missing teeth from birth.
  • A pediatric dentist is especially qualified and trained to handle several dental emergencies that can occur in childhood. It may be a broken tooth, broken braces and wires, a cut or bitten tongue or a knocked-out tooth or a common toothache.
