Dental service has evolved impressively over the course of the past century. While a visit to the dentist may not be among the favorite activities of most people, dental technology has improved to better satisfy patients' needs. Dental tools and implements are constantly enhanced to perform in an area of health services which has gained great recognition. Even though archeologists have found that knowledge of dentistry already existed more than 5,000 years ago, dentistry has only been a profession since the 20th century. Dental extractions were often performed by barbers until the 19th century. Dental tools, on the other hand, were already used more than 600 years ago, when an ancestor of the modern forceps was invented. Whether a patient needs help with a toothache, a filling, teeth cleaning, or a more complex treatment, dental tools are now made to safely satisfy the specifics of the job. Common dental handheld tools include the mouth mirror, explorer, forceps, and saliva ejector. Some dental tools need to be sharp to avoid unnecessary repetition when scaling teeth. Sharp dental tools also demand less grip strength on the part of the dentist. Dentistry demands the use of many instruments that enter into contact with blood or other sterile parts of the body of a patient. Placing these instruments in the chamber of an autoclave will ensure that they are kept clean and free of any hazardous agents, thus protecting the patient's health. The autoclave is a medical sterilization device that permits the application of pressure and heat in order to decontaminate items or render them sterile.
