Upper second premolar root canal

Lower central and lateral incisors - The single root of a lower incisor sometimes has canals. Maxillary Second Premolar. Similar to the first premolar in coronal morphology, the second premolar varies mainly in root form. Its crown is narrower in the buccal-palatal dimension and slightly wider in the mesial-distal.

The canal orifice is centrally located but often appears more as a slot than as a single ovoid opening.

Of the two hundred maxillary second premolars , 64. The average length of the teeth was 21. Concerning the canal morphology, 33. Out of the 1females of the maxillary second premolar had one root and had two roots. Regarding root canal morphology of the female maxillary second premolar had type I, had type II, and had type IV.

If the mesiodistal distance distance is equal to or wider in the root than the crown, expect three roots. The number of canals each first premolar have – have canals , have canal , and have canals. Type IV, are Type II, are Type I.

Two canals may be found in about of cases. The configuration of the two canals may vary with two separate canals and two exits, two canals and one common exit, one canal dividing and having two exits. In one study, it was found that of maxillary second premolars had accessory canals. The maxillary second premolar is one of two teeth located in the upper jaw , laterally (away from the midline of the face) from both the maxillary first premolars of the mouth but mesial (toward the midline of the face) from both maxillary first molars. The wisdom tooth is fully erupted and is where the second molar should have been.

This one failed and I believe it happened when posts were placed after it broke at the gum line. Figure 5) Many mandibular first premolars have significant lingual inclination of the root , making the second canal almost impossible to locate because the lingual canal often branches off the main canal at or near a 90-degree angle. If a single canal is present, it tends to be broad in the buccal-lingual direction, and this makes it difficult to remove biofilm from all root surfaces. How is the root canal shaped in the midroot section of the lower second premolar ? Oval in cross section, becoming more circular towards the apex Why does accidental pulp exposure occur less frequently in the lower second premolar in comparison to the lower first premolar ? Approximately to of maxillary first premolars have canals, while to have just canal. Three-rooted maxillary first premolars are uncommon, with an incidence of 0. Mandibular second premolars have been shown to have root canal at the apex in 97.

It doesn’t hurt more than a filling or any other dental procedure. Root canal treatment is done under profound local anesthetic. The root canal therapy on premolars is a routine, selective procedure. A study by Stropko evaluated the pulpal floor of upper first molars in the region of their mesiobuccal root (a root that frequently has a very minute second canal ).

They did this first by normal visual inspection and then again with the aid of an operating microscope. Canals configurations: Our study showed that 97. I had a root canal done on the second premolar on the upper right side of my mouth about months ago. I initially had problems with it once the temporary crown was put in. For example, the initial bite into any food would cause a lot of pain, but oddly would go away as I continued chewing.

A 49-year-old male patient was referred to the Department of Conservative Dentistry and Endodontics for root canal treatment in his maxillary right second molar. The patient complained of lingering pain in his right upper posterior region of the mouth on consuming cold and hot food and drinks for the past month. Terrible pain after eating anything sweet or salty in root canal and capped teeth. I got root canal treatment for Second Premolar and First Molar. Second Premolar had decay and after root canal it got crowned only after a month as my dentist took time to operate on First Molar.

My first molar had stone or dental pulp on the nerve. The facial ridge is not as prominent as that of the maxillary 1st premolar. Incisors, canines, upper second premolars, lower premolars, have one root and therefore are much easier. This is at variance with the studies of Greenand Vertucci et al.

Larger crown and root than mandibular 1st premolar , therefore larger pulp cavity in crown and upper root canal. Usually have ONE root and canal that may be curve usually DISTALLY. Crown is generally tilted lingually to the long axis of the tooth.

The access cavity has been extended mesially and buccally, at the expense of the mesiobuc-.
