Endodontic therapy premolar

Management of a Maxillary First Premolar. Successful root canal therapy requires a thorough knowledge of root and root canal morphology, as well as the ability to adequately clean, shape and fill all canals. To achieve success in endodontic therapy it is imperative that all the canals are locate cleaned and shaped and obturated three dimensionally.

Maxillary first premolar having three separate roots has an incidence of 0. Even rarer are reported clinical case reports of maxillary second premolar with three separate roots and three canals. The techniques for premolars and molars are quite different.

RESTORING ENDO PREMOLAR TEETH Premolars that have reached the stage of needing endo most often have severely compromised crown structure. This exposes the core design and the remaining tooth structure to potentially damaging stresses. This may be due the extreme variations in root canal morphology of mandibular premolar teeth compared with the standard description of one root and one canal and therefore poses an endodontic challenge to the clinician. The most important requirements for successful endodontic treatment are accurate diagnosis and good knowledge of canal morphology. A mandibular second premolars rarely have more than one root and.

This step is essential not only to determine the extent of the decay, but also to determine how many canals exist in the tooth, (some have more than expected), as well as their shape, which varies depending on the patient.

Multirooted teeth represent a challenge to both endodontic diagnosis and treatment due to its complex and unusual root canal morphology in many cases and often encountered during endodontic treatment. Unusual anatomical configurations must be considered in the radiographic and clinical evaluation during the endodontic treatment. The canal anatomy maxillary first and second premolar has been studied extensively and the presence of three canals is relatively rare especially in the maxillary second premolar. A unique approach to endodontic therapy for dens invaginatus in a maxillary second premolar is pressented. Componentsoftherootcanalsystem The entire space in the dentine of the tooth where the pulp is housed is called the pulp cavity (Fig.

3). Schematic representation of a premolar periapical radiograph which reveals clues about root canal morphology. The average length of mandibular first premolar teeth was 21. All the teeth had cusps.

One hundred thirty four teeth (9 ) had one root, and just teeth () had two roots. Mesial invagination of root was found in teeth (1). How did we come up with these estimates? Root canal treatment for a posterior tooth (molar). What does the above fee include?

Careful evaluation of two or more periapical radiographs is mandatory.

These angled radiographs provide much needed information about root canal morphology. Figures and 2), the reduction of the radiolu-cency in the first premo-lar is indica-tive of heal-ing in progress (see also Figures 4and 5). Regrettably, both the restorations are inadequate.

This can be attributed to variations in the internal morphology of their pulp cavity, considering the number of root canals, apical deltas and lateral canals (115). Tooth Morphology and Access Openings.
