About this deal

Buffrénil, Vivian de; Quilhac, Alexandra (2021). "An Overview of the Embryonic Development of the Bony Skeleton". Vertebrate Skeletal Histology and Paleohistology. CRC Press: 29–38. doi: 10.1201/9781351189590-2. ISBN 978-1351189590. S2CID 236422314. Tooth abnormalities may be categorized according to whether they have environmental or developmental causes. [58] While environmental abnormalities may appear to have an obvious cause, there may not appear to be any known cause for some developmental abnormalities. Environmental forces may affect teeth during development, destroy tooth structure after development, discolor teeth at any stage of development, or alter the course of tooth eruption. Developmental abnormalities most commonly affect the number, size, shape, and structure of teeth. Toothache, and other dental problems, are common presenting complaints in both primary and secondary care. 1 Having a basic understanding of the dentition (or teeth) is important for all healthcare professionals. Permanent (or adult) teeth of which there are 32 in total, made up of 8 incisors, 4 canines, 8 premolars and 12 molars. A skeleton is the structural frame that supports the body of most animals. There are several types of skeletons, including the exoskeleton, which is a rigid outer shell that holds up an organism's shape; the endoskeleton, a rigid internal frame to which the organs and soft tissues attach; and the hydroskeleton, a flexible internal structure supported by the hydrostatic pressure of body fluids.

American Society for Biochemistry and Molecular Biology. 223 (2): 969–975. doi: 10.1016/S0021-9258(18)65095-1. PMID 13385244. The human skull consists of 22 bones (or 29, including the inner ear bones and hyoid bone) which are mostly connected together by ossified joints, so called sutures. The skull is divided into the braincase ( neuro cranium) and the facial skeleton ( viscerocranium). Its main task is the protection of the most important organ in the human body: the brain. Diastema is a condition in which there is a gap between two teeth caused by the imbalance in the relationship between the jaw and the size of teeth.

Superior view

The tooth is made up of a crown and either single or multiple roots. The anterior teeth in both the upper and the lower jaws, from the right first premolar to the left first premolar, are single rooted teeth. On the upper jaw, the maxillary second premolar may have two roots and all of the maxillary molars have two to three roots. On the lower jaw, the mandibular premolar has a single root and the molars have one to two roots. Listgarten, Max A.

Flossing teeth: Using floss or an approved dental gum cleaner cleans teeth below the gum line, where brushing cannot reach. Tooth development is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth. Although many diverse species have teeth, their development is largely the same as in humans. For human teeth to have a healthy oral environment, enamel, dentin, cementum, and the periodontium must all develop during appropriate stages of fetal development. Primary teeth start to form in the development of the embryo between the sixth and eighth weeks, and permanent teeth begin to form in the twentieth week. [25] If teeth do not start to develop at or near these times, they will not develop at all.

The FDI system uses a two-digit numbering system in which the first number represents a tooth's quadrant and the second number represents the number of the tooth from the midline of the face. For permanent teeth, the upper right teeth begin with the number, "1". The upper left teeth begin with the number, "2". The lower left teeth begin with the number, "3". The lower right teeth begin with the number, "4". For primary teeth, the sequence of numbers goes 5, 6, 7, and 8 for the teeth in the upper right, upper left, lower left, and lower right respectively. Tooth extraction: If a tooth is too damaged to repair with a filling or root canal, it may be removed. Wisdom teeth are often extracted to prevent displacement of the other teeth.Silvestro, JR (1977). "Second Dentition and School Readiness". New York State Dental Journal. 43 (3): 155–8.
