TOOTH ANATOMY

In this eLearning module, you will learn about Mandibular 1st molar. The mandibular first molar is the largest tooth in the mandibular arch. It has five well-developed cusps: two buccal, two lingual, and one distal. Mandibular first molars usually have two roots one mesial and one distal. The mesial root exits the crown in a mesial direction and then gradually curves distally in the apical third.

In this eLearning module, you will learn about Maxillary 1st molar. The maxillary first molar is the largest tooth in volume and one of the most complex in root and canal anatomy. It has four well-developed functioning cusps and one supplemental cusp of little practical use.The crown of this tooth is wider buccolingually than mesiodistally. Usually the extra dimension buccolingually is about 1 mm. The pulp chamber is widest in the buccolingual dimension, and four pulp horns are present.

In this eLearning module, you will learn about Maxillary 1st pre molar. The maxillary first premolar is the fourth permanent tooth from the median line in the maxillary arch, located laterally from both the maxillary canines of the mouth but mesial from both maxillary second premolars. It is the first posterior tooth. It have have two cusps bicuspid & two roots, buccal & lingual. The buccal cusp is usually about 1 mm longer than the lingual cusp. The crown is angular, and the buccal line angles are prominent.

In this eLearning module, you will learn about Maxillary canine. Maxillary canines are the longest teeth in the mouth. The crowns are usually as long as those of the maxillary central incisors, and the single roots are longer than those of any of the other teeth.The permanent maxillary canine replaces deciduous maxillary canine & is located 3rd from midline in each maxillary quadrant. The outline of the labial or lingual aspect of the maxillary canine is a series of curves or arcs except for the angle made by the tip of the cusp.

In this eLearning module, you will learn about Mandibular canine. The mandibular canine is a strategically important tooth in the dental arch. It is similar to maxillary canines except that they are slightly narrower mesiodistally. The single roots are longer than those of any of the other teeth. The middle labial lobes have been highly developed incisally into strong, well-formed cusps. Crowns and roots are markedly convex on most surfaces.

In this eLearning module, you will learn about Mandibular 2nd premolar.The Mandibular 2nd premolar has a larger crown and longer root than lower one. In the 2nd premolar the lingual pulp horn usually is larger. The root and root canal are more often oval than round, the pulp chamber is wider buccolingually, and the separation of the pulp chamber and root canal is normally distinguishable compared with the more regular taper in the first premolar.

In this eLearning module you will learn about Maxillary Central Incisor. The maxillary central incisor is the widest mesiodistally of any of the anterior teeth. They are the most prominent teeth, having a rectangular or square shape. The maxillary central incisors are centered in the maxilla, one on either side of the median line, with the mesial surface of each in contact with the mesial surface of the other.
