What is the most common root canal system for maxillary second premolars?

In this study, variable root canal configurations were found in maxillary second premolars. Type II configuration was most prevalent (33.6%) followed by type IV (31.1%), type I (29.2%), type V (2.1%), type III (1.3%), type VI (1.2%), and type VII (1%) [Figure ​1a–g].

Where is the maxillary second molar?

The maxillary second molar is the tooth located distally (away from the midline of the face) from both the maxillary first molars of the mouth but mesial (toward the midline of the face) from both maxillary third molars. This is true only in permanent teeth.

Can a premolar have 3 canals?

The anatomy of a maxillary premolar with three canals, mesio buccal, distobuccal and palatal is similar to the adjacent maxillary molars and they are sometimes referred to as small molars or radiculous3. In a case of three root canals, the buccal orifices are not clearly visible with the mouth mirror.

Can a second molar have more than two canals?

This root can have more than two canals according to Ozcan et al. 11 who reported a case of a maxillary second molar with 3 canals in the mesio buccal root and Caliskan et al. 12 who showed that 16% of second maxillary molars had 3 canals in this root (Table 5). – Canals configurations:

What makes the maxillary second molar different from the first molar?

The distinguishing morphologic feature of the maxillary second molar is its three roots grouped close together, and sometimes fused. The parallel root canals are frequently superimposed radiographically. They are usually shorter than the roots of the first molar and not as curved.

How many canal are there in the maxillary root?

6- Different canal configurations observed at the lingual root (Figure 4) In the present study, 93 % of maxillary first molars were 3 rooted. Our results are similar to the findings of Libfeld 4 (90.6%), Neelakantan 5 (93.1%) and Sert 6 (91.27%).

What’s the name of the fourth molar root canal?

It’s often referred to as the “fourth canal” and is one of the most frustrating aspects of maxillary molar root canals. We have known of the presence of the MB2 canal for over a century. In 1917, Professor Walter Hess injected root canals of human teeth with vulcanized rubber and then removed the hard tooth tissues by decalcification.
