Maxillary 2nd molar

What are first permanent molars? This is true only in permanent teeth. The maxillary second molar consists of four cusps: the largest is the mesiopalatal followed by the mesiobuccal, and the distopalatal cusp is the smallest.

Access in both teeth can usually be adequately prepared without disturbing the transverse ridge. The second molar is often easier to prepare because of the straight-line access to the orifices.

Buccal pit is present in both molars. The occlusal surface of the Molar consists of cusps which help in mastication of food or chewing. They decrease in size as they go posteriorly therefore the first molar is the largest, then the second molar and lastly the third molar. MAXILLARY FIRST MOLAR It is the largest tooth in the maxillary arch.

The maxillary first molar is the human tooth located laterally (away from the midline of the face) from both the maxillary second premolars of the mouth but mesial (toward the midline of the face) from both maxillary second molars. Maxillary molars have roots with tripod arrangement, which enhance the anchorage in alveolar bone. The presence of oblique ridge on the occlusal surface is a characteristic feature of the maxillary molar.

The crown of the maxillary molar is more centered over the root. Molar root fusion is one of the most commonly found anomalies in the development of root morphology. Root fusion is found more frequently in maxillary than in mandibular molars.

It is more common in the third molars, followed by second molars, and less often in the first molars, in both arches. The permanent maxillary second premolar is the fifth tooth from the midline. This tooth is a succedaneous tooth, replacing the deciduous maxillary second molar. The maxillary second premolar tooth shares a mesial contact with the maxillary first premolar and a distal contact with the maxillary first molar. The same shape as maxillary first molar but with more rhomboidal shape.

Heart shape take the same shape of maxillary third molar. The distolingual cusp is poorly developed. A maxillary second molar supplements a first molar’s function. Generally speaking, the differences that occur between the first and second molars are even more accentuated between the first and third molars.

Lower central and lateral incisors - The single root of a lower incisor sometimes has canals. In particular, anticipation of rare anatomical variations should be crucial for endodontic specialists. Such a dental anomaly is the presence of two palatal roots in human maxillary second molars.

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 maxillary second- molar extraction group exhibited distal movement of the maxillary first molar ( mm vs mm), and there was greater flaring of the mandibular incisors in the nonextraction. The maxillary third molar vary considerably in size, form and relative position to the other teeth. It is seldom as well developed as the second molar which it often resembles.

Its crown is smaller, the roots are shorter with great tendency for fusion resulting in one tapered root. Start studying Chapter molars. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Importance of Primary Teeth.

The loss of the deciduous teeth tends to mirror the eruption sequence: incisors, first molars , canines, and second molars , with. Maxillary Second Molar - root formation may be different from first molar - usually three canals - access similar to maxillary second molar (blunted triangular - outline) - always look for four canals - more variability of anatomy in second and third molars compared to first molar.
