Premolar Root Canal Nuevo Progreso

Similar to the first premolar in coronal morphology, thesecond premolar varies mainly in root form. Its crown is narrower in thebuccal-palatal dimension and slightly wider in the mesial-distal. The canalorifice is centrally located but often appears more as a slot than as a singleovoid opening. When the slot-shaped opening appears, the clinician must assumethat the tooth has two canals until proved otherwise. The basic outline of thetooth is slightly ovoid but wider from mesial to distal than the outline of thefirst premolar. All caries and leaking restorations must be removed andreplaced with a suitable temporary restoration. Radicular morphology maypresent two separate canals, two canals anastomosing to a single canal, or twocanals with interconnections or "webbing." Accessory and lateralcanals may be present, but less often than in incisors. Vertucci and associatesstated that 75% of maxillary second premolars in their study had one canal atthe apex, 24% had two foramina, and 1% had three foramina. Of the teeth studied,59.5% had accessory canals. These clinicians also reported that when two canalsjoin into one, the palatal canal frequently exhibits a straight-line access tothe apex. They further pointed out that "if, on the direct periapicalexposure, a root canal shows a sudden narrowing, or even disappears, it meansthat at this point the canal divides into two parts, which cither remainseparate (type V) or merge (type II) before reaching the apex." The rootlength of the maxillary second molar is much like that of the first premolar;and apical curvature is not uncommon, particularly with large sinus cavities.After endodontic treatment, full occlusal coverage is mandatory to ensureagainst vertical cuspal or crown-root .

A root canal is the space within the root of a tooth. It is part of a naturally occurring space within a tooth that consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.At the center of a tooth is a hollow area that houses soft tissues, such as the nerve, blood vessels, and connective tissue. This hollow area contains a relatively wide space in the coronal portion of the tooth called the pulp chamber.These canals run through the center of the roots like pencil lead through the length of a pencil. The pulp receives nutrition through the blood vessels and sensory nerves carry signals back to the brain.

No toothache is a good toothache. But a toothache can seem especially nasty when it is one of your molar teeth, the largest teeth found in the back of your mouth. Used for chewing and grinding food, molars are important to your oral health. Without them you wouldn’t be able to eat -- and your jawbone would start to deteriorate, giving your cheeks the sunken look that’s often associated with aging.A toothache could be a sign your molar needs a root canal -- or molar endodontics, as dentists and endodontists might refer to it. Regardless, any sign of tooth discomfort means you should see a dentist -- and fast!
