The arrows point in the following directions: distal ←, mesial →, coronal ↑, apical ↓. Distal The direction toward the gingiva beyond the tooth furthest from the anterior midline (the 'most posterior tooth' or last tooth) in each quadrant of a dental arch, as opposed to mesial, which refers to the direction toward the anterior midline.
Coronal places of articulation include the dental consonants at the upper teeth, the alveolar consonants at the upper gum (the alveolar ridge), the various postalveolar consonants (including domed palato-alveolar, laminal alveolo-palatal, and apical retroflex) just behind that, the subapical retroflex consonants curled back against the hard palate, and linguolabial consonants with the tongue ...

The voiceless alveolar, dental and postalveolar plosives (or stops) are types of consonantal sounds used in almost all spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental , alveolar , and postalveolar plosives is t , and the equivalent X-SAMPA symbol is t .
In addition, payment to dental professionals is based on the CDT code(s) reported on the ADA Claim Form, so using the most current codes helps to maximize reimbursement and minimize audit liability. [6] In the near future, dental professionals will be required to use diagnosis codes in support of the procedures and services they provide.
As the International Phonetic Alphabet does not have separate symbols for the alveolar consonants (the same symbol is used for all coronal places of articulation that are not palatalized), this sound is usually transcribed θ̠ , occasionally θ͇ (retracted or alveolarized [θ], respectively), ɹ̝̊ (constricted voiceless [ɹ]), or t̞ ...
A labial–coronal consonant is a consonant produced with two simultaneous articulators: with the lips ('labial'; a , , or sound), and with the tongue (at the teeth or gums, a 'dental' or 'alveolar' , or sound, or further back, a 'post-alveolar' or 'retroflex' , or sound).
A dental consonant is a consonant articulated with the tongue against the upper teeth, such as /θ/, /ð/. In some languages, dentals are distinguished from other groups, such as alveolar consonants , in which the tongue contacts the gum ridge.
