Comparison between root of maxillary 1st and 2nd molar

Mandibular Molars
Let us first see the meaning of the two terms, maxillary, and mandibular, before looking at the difference between them. Maxillary molars are the molars in the upper jaw while mandibular molars are the molars in the lower jaw. In an adult, there are four types of teeth found in both maxilla and mandible, namely; incisors (8), canine (4), premolars (8), and molars (12). In this article, we mainly focus on the difference between maxillary and mandibular molars. There are 6 molars in each arch, and three molars on either side of the arch. The crown of the molars has modified into an occlusal (chewing) surface with 3 to 5 cusps. Moreover, the occlusal surfaces of molars are larger than that of other teeth. The main roles of molars include the mastication of food, maintenance of vertical dimension of the face, and help to keep other teeth in proper alignment. The key difference between them can be observed in their position and the structure.
What are Maxillary Molars?
Maxillary molars are the 6 molars on maxillary arch. In lingual view, geometric form of these molars is a trapezoid. In occlusal view, these teeth are rhomboid with 2 acute and 2 obtuse angles. They have two buccal cups and one buccal groove. The buccal surface is relatively verticle. Maxillary molars have 3 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.
