What is a palatogingival groove?
What is a palatogingival groove?
Palatogingival groove or radicular lingual groove (RLG) is a developmental anomaly that occurs as developmental infoldings of the inner enamel epithelium and Hertwig’s epithelial root sheath (HERS), involving primarily maxillary lateral incisors.
How is Palatogingival groove treated?
The treatment approach for teeth with PGG is based on the following three strategies: (i) complete eradication of microbials, (ii) permanent and thorough sealing of the root groove that communicates between the root canal and the periodontium, and (iii) periodontal regeneration and complete healing of the periodontium.
What is Palato-radicular groove?
Palato-radicular groove (PRG) is one of the rare developmental anomalies of maxillary incisor teeth, primarily maxillary lateral incisor. It usually begins in the central fossa, crosses the cingulum and extends to varying distance apically, possibly reaching the root apex.
Where is the location of lingual gingival groove?
They are usually found on the lingual surface of maxillary lateral incisors. They have an incidence rate ranging from 2.8% to 18%. They originate when the central fossa crosses the cingulum and extend toward root portion in apical direction.
What is dens in dente?
“Dens in dente” is a developmental malformation incident due to the in folding of enamel and dentin or an accentuation of the lingual pit of an incisor before calcification sets in.
What is a developmental groove?
n. One of the fine lines found in the enamel of a tooth that mark the junction of the lobes of the crown in its development.
How can you tell the difference between a left and right dog?
- To distinguish a right mandibular canine from a left mandibular canine; remember:
- • The distal cusp ridge is longer than the mesial cusp ridge.
- • The mesial surface of the crown is almost parallel to the long axis of the tooth.
How do you distinguish between left and right lateral incisors?
In the Palmer notation, a number is used in conjunction with a symbol designating in which quadrant the tooth is found. For this tooth, the left and right lateral incisors would have the same number, “2”, but the right one would have the symbol, “┐”, over it, while the left one would have, “┌”.
What is Invaginatus den?
Dens invaginatus is a malformation of teeth probably resulting from an infolding of the dental papilla during tooth development. Affected teeth show a deep infolding of enamel and dentine starting from the foramen coecum or even the tip of the cusps, and which may extend deep into the root.
