Upper 2nd premolar canals

Of the two hundred maxillary second premolars , 64. The average length of the teeth was 21. Concerning the canal morphology, 33.

Lower central and lateral incisors - The single root of a lower incisor sometimes has 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. 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 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.

Type IV, are Type II, are Type I. The rest are pretty small percentages. Vertucci also showed that the second premolar had one canal at the apex in 97. Occasionally, the canal terminates with an extensive delta, making obturation of the accessory canals even more challenging.

As in the upper premolars , the access cavity is oval between the cusp tips. Root and root canal morphology of third molars in a Jordanian subpopulation.

Chapter: Morphology of Teeth and Their Root Canal Systems. Al-Ghananeem MMF, et al. The Number of Roots and Canals in the Maxillary Second Premolars in a Group of Jordanian Population. 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. Root canal treatment is also performed in this region.

How can I differentiate the first and second premolar ? You can differentiate both premolars through their morphological appearance. However, the functionality of both premolars is relatively same. As with first premolars, many mandibular second premolars have some lingual inclination of the root and a broad buccal-lingual canal dimension in difficulty contacting all surfaces of the canal with any instrumentation technique. How is the position of the base of the pulp chamber in the upper second different to the upper first premolar ? Placed further apically than upper first before narrowing to single root canal How is the pulp cavity shaped in the upper second premolars ? Pecora and co-worker reported that out of 4maxillary second premolars studie 67.

The incidence of two canals at the apex is reported to range from to. The majority of mandibular second permanent premolars have a single root canal system (9 type I) and two canals in the remainder ( type IV). Maxillary premolars - first premolars - mostly canals - second premolars - mostly l canal - access-ovoid shaped in bucco-lingual direction - pulp broad bucco-lingually - narrow mesiodistally. A branch of biology that deals with the form and structure of animals and plants.

The form and structure of an organism or any of its parts. The facial ridge is not as prominent as that of the maxillary 1st premolar. The lower second premolar almost always presents with two lingual cusps.

The lower premolars and the upper second premolar usually have one root. The upper first usually has two roots, but can have just one root, notably in Sinodonts, and can sometimes have three roots. Various case reports have been published and reported three canals in the maxillary second pre-molars. Vertucci performed a research on the root canal morphology of different teeth and reported three canals in of two hundredext ractedm axillary second premolars.

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. To determine the frequency of two canals in relation to age and gender as well as role of shift cone angle radiographic technique in maxillary second premolar tooth.
