Dental anatomy upper first molar

What are the 4 roots of the upper first molar?
These roots were designated due to their anatomical position as mesiobuccal, distobuccal, and palatal root, usually exhibiting four root canals (mesiobuccal root with a second canal, whereas the other roots commonly contain only one canal) [3, 4]..
What is the anatomy of the upper first molar?
Maxillary first molars.
The maxillary first molars are three rooted, two buccal and one palatal.
The mesiobuccal root is broad in the buccopalatal plane and narrow in the mesiodistal plane, similar to a maxillary premolar root configuration.
The root generally exits the crown mesially and can abruptly curve distally..
What is the anatomy of the upper first molar?
The first maxillary molar has three roots - mesiobuccal , distobuccal and lingual .
The lingual root is the largest and longest of all roots, and it contains a lingual root depression.
The mesiobuccal root presents with mesial and distal root depressions..
What is the dental anatomy of the primary maxillary first molar?
First Molars – The maxillary first molars (tooth B, I) morphologically resemble both a molar and a premolar.
Its occlusal surface consists of the mesiobuccal, distolingual, mesiolingual, and distobuccal cusps.
The largest cusp is the mesiolingual cusp, and it also represents the sharpest cusp..
Why do upper molars have 3 roots?
A rare dental trait that is more common in Asian and Native American populations – three-rooted molars – could have its origins in trysts with our archaic relatives, the Denisovans, according to new research..
External root morphology
The maxillary first molar normally has three roots.
The mesiobuccal root is broad distobuccal and has prominent depressions or flutings on its mesial and distal surfaces.
The internal canal morphology is highly variable, but the majority of the mesiobuccal roots contain two canals.
The anatomical characteristics of permanent maxillary molars are complex and are generally described as teeth with three roots: Two buccal root canals and one palatal root canal[1].
There are usually four cusps on maxillary molars, two on the buccal (side nearest the cheek) and two palatal (side nearest the palate).
There may also be a fifth smaller cusp on the palatal side known as the Cusp of Carabelli.

What is the difference between a first molar and a distobuccal tooth?

Its roots are as long or even longer than the first molar’s

The distobuccal cusp is not as large and well-developed, and the distolingual cusp is smaller

The crown of this tooth is approximately 0

5 mm shorter cervico-occlusally than the one of the first molar, but buccolingually the dimensions are about the same

Viewed from the top of the tooth (occlusal view), the mandibular first molar is pentagonal (five sided) in shape and tapers toward the lingual, with the sides being the buccal surface, the mesial surface, the lingual surface, distal surface, and the distobuccal surface. The occlusal surface has four grooves.
