  2. Molar (tooth) - Wikipedia

    en.wikipedia.org/wiki/Molar_(tooth)

    A brachydont tooth has a crown above the gingival line and a neck just below it, and at least one root. A cap of enamel covers the crown and extends down to the neck. Cementum is only found below the gingival line. The occlusal surfaces tend to be pointed, well-suited for holding prey and tearing and shredding. [10]

  3. Maxillary first molar - Wikipedia

    en.wikipedia.org/wiki/Maxillary_first_molar

    The maxillary first molar normally has three roots. 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 ca

    Cementum is a specialized bone like substance covering the root of a tooth. [15] It is approximately 45% inorganic material (mainly hydroxyapatite), 33% organic material (mainly collagen) and 22% water. Cementum is excreted by cementoblasts within the root of the tooth and is thickest at the root apex. Its coloration is yellowish and it is ...

    en.wikipedia.org/wiki/Dental_anatomy

    Dentin composes most of the root, which normally has pulp canals. The roots of teeth may be single in number (single-rooted teeth) or multiple. Canines and most premolars, except for maxillary first premolars, usually have one root. Maxillary first premolars and mandibular molars usually have two roots. Maxillary molars usually have three roots.

    Nonetheless, it is known that cellular cementum is usually not found in teeth with one root. [36] In premolars and molars, cellular cementum is found only in the part of the root closest to the apex and in interradicular areas between multiple roots.

  7. Mandibular first molar - Wikipedia

    en.wikipedia.org/wiki/Mandibular_first_molar

    The mandibular first molar or six-year molar is the tooth located distally (away from the midline of the face) from both the mandibular second premolars of the mouth but mesial (toward the midline of the face) from both mandibular second molars. It is located on the mandibular (lower) arch of the mouth, and generally opposes the maxillary ...

  8. Idiopathic osteosclerosis - Wikipedia

    en.wikipedia.org/wiki/Idiopathic_osteosclerosis

    Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.

  9. Root canal - Wikipedia

    en.wikipedia.org/wiki/Root_canal

    A root canal is the naturally occurring anatomic space within the root of a tooth.It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.
