What is the treatment for an infected root canal? What are the signs of a root canal infection? Should I get a root canal or pull the tooth? 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. The permanent maxillary second molar : Canal number And configurations in a Tunisian population One of the major causes of failure in endodontic treatment is the impossibility of locating and treating the entire root canal system, a result of the lack of knowledge regarding the dental, internal or external anatomy. Vertucci reported the occurrence of one canal at the apex in them at , and two canals at apex at.
In the same study, Vertucci found maxillary second premolars with three canals at apex to be only. Of the two hundred maxillary second premolars , 64. The average length of the teeth was 21.
Concerning the canal morphology, 33.
The aim of this study was to investigate the number of roots and root canals in the maxillary second premolar in a group of Jordanian population. The maxillary second premolars show an even lesser incidence of 0. Even rarer are reported clinical cases of maxillary second premolar with three separate roots and three canals. How many canals do first and second upper premolars have? The number of roots and root canals in the maxillary second premolars was recorded. A total of 2patients 1female () and 1male () received root canal treatment of maxillary second premolar.
The mean age of the patients was 32. The function of this premolar is similar to that. The permanent maxillary second molar: Canal number And configurations in a Tunisian population One of the major causes of failure in endodontic treatment is the impossibility of locating and treating the entire root canal system, a result of the lack of knowledge regarding the dental, internal or external anatomy.
Second premolars vary individually more than first premolars. A maxillary second premolar may have a crown that is noticeably smaller cervicoocclusally and mesiodistally. On the other han it may be larger in those dimensions and usually is.
Generally the root of a second premolar is longer than that of a first premolar. These studies were aimed to check the distribution with type of canals. This was, however, not investigated and is the limitation of the study. Vertucci also showed that the second premolar had one canal at the apex in 97.
Background: The aim of the case report is to demonstrate the importance of knowing the root canals configuration in the maxillary second premolars.
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.
Lower central and lateral incisors - The single root of a lower incisor sometimes has canals.
