The mandibular canines are slightly narrower than the maxillary canines but its crown is as long and sometimes is longer. The mandibular canines usually have only one root, but sometimes the root may be bifurcated, or have two roots. When ...
Retention demands are significantly less following serial extraction. However it is better to follow a regular retention regimen for the first six months against possible relapse of rotations and to allow settling of the occlusion. A maxillary Hawley type retainer and a bonded mandibular canine to canine retainer make an efficient retention ...

Periapical COD occurs most commonly in the mandibular anterior teeth while focal COD appears predominantly in the mandibular posterior teeth. Florid COD is an extensive variant of periapical COD where lesions occur in multiple quadrants which can encompass the maxilla and mandible, and infrequently can cause jawbone deformity.

Root canal (endodontic treatment) Extraction; The condition is usually benign, but it can cause mild irritation to soft tissues around the teeth and the tongue, and if large enough, may pose an aesthetic problem. Talon cusps that are too large are filed down with a motorized file, and then endodontic therapy is administered.
Peg laterals typically occur on both sides, [2] and have short roots. [2] Inheritance may be involved, [2] and the frequency of microdontia in the upper laterals is just under 1%. [1] The second most commonly involved tooth is the maxillary third molars, [3] and after this supernumerary teeth. [3]
