4. Reading and notetaking

1. On a first read - identify main topic and features

The permanent anterior teeth include the two central incisors, two lateral incisors, and two canines. The central incisors are closest to the midline, the lateral incisors are the second teeth from the midline, and the canines are the third teeth from the midline. All anterior teeth are succedaneous, which means they replace primary teeth of the same type.

All anterior teeth have a cingulum, a rounded raised area on the cervical third of the lingual surface. The lingual surface has rounded, raised borders in the mesial and distal surfaces called marginal ridges. Some anterior teeth have a fossa, a wide shallow depression on the lingual surfaces

Task 1

  • Read the passage below using the 'strategies for reading' outlined.
  • Take notes in point form and submit to your teacher

Maxillary molars
The maxillary molars assist the mandibular molars in performing the major portion of the work of mastification. They are usually the first permanent teeth to erupt into the maxillary arch. Because of both their size and their 'anchorage' in the jaws, the molars are the largest and strongest maxillary teeth. Each maxillary molar usually has four cusps, with two cusps on the buccal portion of the occlusal table and two on the lingual.

Each maxillary molar has three well separated and well developed roots. A tooth with three roots is said to be trifurcated, which means divided into thirds. A trifurcation is the area at which the three roots divide. Because maxilllary molars are trifurcated, the three divisions are usually located on the mesial, buccal and distal surfaces. They provide the tooth with maximum anchorage against occlusal forces. All maxillary molars are wider buccolingually than mesiodistally (Torres & Ehrlich 2005, p. 167)
