Maxillary molar roots

How many roots does the maxillary first premolar have? What are the maxillary teeth? 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. A maxillary first molar has typically three separate roots and in only about of the cases just two roots are found.

Two or more merged roots occur in about of all cases.

In second maxillary molars , merging of roots is much more common. The buccal root of the maxillary molars was more commonly protruded into the maxillary sinus. Among the roots of maxillary posterior teeth (from first premolar to second molar), mesiobuccal root of first molar and palatal root of second premolar were found in close proximity to the floor of maxillary sinus.

The presence of oblique ridge on the occlusal surface is a characteristic feature of the maxillary molar. The parallel root canals are frequently superimposed radiographically. They are usually shorter than the roots of the first molar and not as curved. Such roots should normally be removed early rather than late in order to minimize the likelihood of maxillary sinus complications.

In some cases, the sinus cavity can be irrigated with saline (antral lavage). Maxillary Sinus Involvement Teeth, roots and other foreign bodies can occasionally be displaced into the maxillary sinus.

Although they are sometimes seen as a chance asymptomatic finding on routine X-rays, such foreign bodies are generally removed because of the possible complication of sinus infection or polyp formation. Maxillary molars are teeth of clinical interest as they present with wide range of anatomical variations in their roots and in their canals. Apart from the usual three root anatomy of maxillary second molar , few studies have recorded occurrence of an extra palatal root in maxillary second molar making an uncommon ‘four root’ scenario. Lower central and lateral incisors - The single root of a lower incisor sometimes has canals. Principal identifying features 1- Rhomboidal occlusal outline.

The cusp of carabelli (non functional cusp), on the lingual surface of the mesiolingual cusp. Three well separated and well developed roots. Such a dental anomaly is the presence of two palatal roots in human maxillary second molars. The maxillary first molar normally has three roots. STOP CHASING or LUNGING at CARS on a Walk!

The anatomical relation of roots and their root canals were identified and were subsequently named based on definite sets of criteria. There is also bilateral maxillary sinus mucosal thickening. A new method for identification and naming of roots and root canal anatomy in maxillary molars , based on their root and canal relationship, was formulated and is presented in this paper. Maxillary First Molar buccal veiw of root the lingual root is the longest, the mesiobuccal root is the widest, and the distobuccal root is the straightest.

Type III maxillary molars are “constricted in root morphology with the MB, MP and DP canals encaged in a web of root dentin. Buccal roots are usually close together, and the palatal root diverges widely toward the palate. The palatal root is often curved buccally in its apical third.

Of the three canals, it offers the easiest access and has the largest diameter.

In the present study, of maxillary first molars were rooted. Our are similar to the findings of Libfeld (9 ), Neelakantan (9 ) and Sert (9). A thorough understanding of internal and external anatomy of various teeth is critical for a successful outcome of endodontic therapy.

The aims of this paper were (1) to describe the clinical retreatment of a maxillary second molar with two palatal roots and (2) to review the available literature regarding this anatomical variation. The Maxillary sinus is the one which is in close proximity to the Maxillary 2st molar on either side of the face. Because of the close proximity of the roots of the Maxillary 1st molar the chance of transferring the infection are greater. Signs of chronic sinus disease in the left maxillary sinus. CT scan shows a tooth-like structure into this maxillary sinus.

It`s also noted a bone discontinuity on the floor of the maxillary sinus. This patient has signs of chronic sinusitis probable and erosion of left maxillary floor with molar tooth migration within the sinus. Maxillary Second Molar compare to the max first molar -the crow of the max second molar is shorter -the root is as long or longer, but the roots are the same length and tipped distally.

It is the ones that had previous root -canal treatments that worry us, because those do get broken roots quite frequently (with the potential for shoving a broken tooth root into the sinus).
