Cavities (Don't wait until it hurts)

Cavities or dental caries are the decayed areas of your teeth that develop into tiny openings or holes. Cavities are referred as the disease of civilized people because of the changed food habits causing them.
They are one of the most common dental problems all around the world due to the shifting food habits of the people over past few years. The trend of eating more of soft and junk food, staying away from diets rich in fruits, fibers and vegetables along with high intake of refined sugar and carbonated soft drinks is one of the main reasons for Dental Cavities. They are especially common in children and young adults. But anyone who has teeth can get cavities , including infants and older people.

Your mouth like many other parts of your body, contains many types of bacteria. Some of these bacteria thrive on food and drinks that contains sugars and cooked searches, also known as fermenting carbohydrates. When these carbohydrates are not cleaned away from your teeth, the bacteria present in your mouth can convert them into acid within no time. The bacteria, acids, food particles and saliva then from into Dental Plaque- a sticky film or layer coats your teeth. The acids in plaque attack minerals in the mouth in the tooth hard outer surface called the Enamel. This erosion causes tiny openings or holes in the enamel cavitiesOnce the spots of enamel are worn away, the bacteria and acid can reach the next layer of your teeth, called Dentin. This layer is softer and less resistant to acid than enamel, so once tooth decay reaches dentin, the decay process speeds up. As the tooth decay continues, the bacteria and acid continue to reach deeper layer of your teeth, that is Pulp. The pulp contains nerves and blood vessels which causes toothache, sensitivity and pain. Further it may lead to swelling called tooth abscess. Tooth decay most frequently occurs in back chewing teeth- molars and premolars. These teeth have lots of natural grooves, pits and fissures.

Computers and dentistry

The use of computers in dental office and in dental education has become the standard of practice. Mobile and miniature devices habe replaced standard textbook, paper databases, even live lectures and redefined the learning process itself.

The digital dental office :
The concept of high tech electronic and fully digitized systems to manage a dental office and integrated clinical tasks is becoming the standard model of current practice. A rapidly developing management product is the internet based software provided by an application service provider (ASP). This product exists in two different platforms :

  • web-hosting
  • web-based

The history of the development of the dental software is brief. For the first time the computers have been used in the dental medicine in the 1960s[1]. Since then computers and information technologies spread progressively in the dental practice. According to Atkinson, J. in the year of 2000 85,1% of all dentists in the United States use computers

There are many kind of dental software, which depends on specific task, that they do to help the dental practice. One classification is given from Schleyer and Kirsher. They categorize three main categories of dental software: administrative, clinical, and for internet. The clinical category from other side is categorized in: electronic dental records, electronic dental designs, dental imaging software, and software used for diagnostics and treatment

Zimmerman recognizes the following types of computer software, depending from their task: administration and management of patients documentation. electronic archives of the documentation. telecommunication computer - aided education computerizing instruments and techniques in the dental office software helping the clinical decision making. All classifications of dental software are relative, since there are software products, designed for realizing more than one task. A larger classification based on the specific task shows more types of tasks and software. 

This classification of dental software is:

  • Dental administration management
  • Dental practitioners records management
  • Dental schedules and dental scheduling
  • Patient dental records management
  • Dental billing
  • Dental imaging processing
  • Dental diagnostics
  • Dental treatment helping
  • Computer aided dental education
  • Software for usage of dental instruments and other techniques used in the dental practice

Free dental software
There are several types of free dental software: shareware, freeware and open source dental software. Most frequently the free dental software is provided as shareware. This means, that the dental software license allows its usage only for evaluation purposes.
