The protaper is a member of the tracheal family. It consists of two leaflets that start straight out from the tip of the trunk to the base of the skull at the base of the neck. The protaper functions as an attachment point for the soft palate, uvula and tonsils. The term “proper” refers to the middle area inside of the apical foramen.
Modern instruments for inspecting and treating the upper airway are based on the standard mechanic’s method for inspecting the protaper. This includes measuring the length of the protaper along the anterior wall of the frame by means of interferon gamma or fluoroscopy with an eye tube. The size and shape of the protaper are using to determine the exact location and depth of the root canal or cleft. The shape of the protaper and the length and depth of the root canal correlate directly to the functional significance of the instrument.
One of the most common uses of the protaper is for determining the root canal depth. In the past, the only way to do this was by making an incision into the soft tissue of the skull using the tip of the tracheoscopy. Today, a variety of special dental tools, including computers, computerized tomography (CT) scanners and instrumentation used for bone diagnosis and for real time x-ray processing make it possible to precisely determine the working length of the root. This is a critical function because many people will not have adequate dental health insurance to cover the full cost of the root canal treatment if it turns out to be too deep. Having the proper working length means that the physician does not have to resort to emergency measures such as crowning the tooth or cutting the underlying gum tissue in an attempt to save the tooth or teeth.
Another widely practiced technique for analyzing the root canals involves a computerized tomography (CT) scanner which is used for the same purpose but produces detailed images of the tooth’s internal structures. Once the images are obtained, the dentist can interpret the data and decide whether the pulp cavity lies within the central portion of the engine, the central section of the maxillary sinus, or somewhere else. Many practitioners believe that biopsies or tissue sampling from the apical foramen are better means of diagnosing central bone or tissue diseases as opposed to the application of a coronal method for root canals or the apical foramen technique. While biopsies are often successful in diagnosing osteoporosis, cardiovascular disease, and small bone cancers, they are unable to diagnose other conditions that lie outside of the teeth’s centers.
Root canals are categorized into three types: coronal, parabolic, and mixed. Coronal canal canals are the largest and deepest and are located inside the bone. The thickness of the bone surrounding the canals varies dramatically from thin to thick. Parabolic canals run along the surface of the tooth and are shallow in comparison to coronal canal canals. Mixed canals occur between parabolic and coronal canals.
Before a tooth specialist begins to work on your teeth, the first step is to have the tooth’s surface, including the roots and crown, examined by a professional dentist. The dentist may then begin the process of root canal preparation. It is important to remember that although the tools used for root canal preparation may be similar, no two practitioners or dental procedures are alike. For this reason, it is recommended that you work with only an experienced professional who utilizes state of the art equipment to ensure proper procedure and treatment.
