  Incisor - Wikipedia, the free encyclopedia
Incisors are the first kind of tooth in heterodont mammals.
The incisors of rodents grow throughout life and are worn by gnawing.
The types of incisors are the maxillary central incisor, maxillary lateral incisor, mandibular central incisor, and mandibular lateral incisor.

 Incisors   (Site not responding. Last check: 2007-10-29)
The maxillary lateral incisor is the second tooth from the midline and the smallest in the maxillary arch.
It is relatively smooth, and the structures are not as prominent as in maxillary centrals.
The crown of the lateral incisor is shaped the same as the central incisor except that the distal surface is not as long.

 THE PERMANENT INCISOR TEETH
Maxillary incisors by definition arise in the premaxilla (which is merged into the maxilla in humans); mandibular incisors are the teeth that articulate with them.
Facial: The mandibular central incisor is the smallest tooth in the dental arch.
Mesial and distal outlines descend apically from the sharp mesial and distal incisal angles.

 PCSO Bulletin: Summer 2000 Dr. John Moore Lecture Summary
The decision to choose the single lower incisor extraction treatment option is based on facial balance, where extraction of premolars would have a negative effect, and when the amount of crowding in the mandibular arch is greater than that in the maxillary arch.
Central incisors are typically.5mm narrower than lateral incisors and, therefore, he preferred choice for extraction.

Numbers 17 through #32 are in the mandibular arch; the lower left third molar is #17, the lower left second molar is #18, and as you proceed around the mandibular arch to the lower right third molar you end with #32.
The occlusal surface of a cusp is composed of a mesial and a distal incline.
The right maxillary central incisor may be distinguished from the left maxillary central incisor because the distoincisal angle is more rounded than the mesioincisal angle, and the incisal edge slopes slightly gingivally in a mesiodistal direction.

The facial surface of the central incisors should be 5-9 mm anterior to the center of the incisive papilla.
The long axis of the mandibular incisor should be slightly inclined distally at the cervical portion of the tooth.
Alternatively, the mandibular canines can be arranged first in the proper relationship to the maxillary canines (the cusp tip of the mandibular canine is placed between the maxillary canine and lateral).

 Dental measuring instrument - Patent 4762491
A hand-operated dental measuring instrument used particularly by orthodontists, dentists, and technicians for rapidly indicating and/or monitoring the incisor tooth labial inclination, which is the inclination of the incisor crown to occlusal plane, of a patient's natural teeth or the plaster cast reproductions of a patient's mouth.
The angle formed by a tangent drawn to the anterior or labial surface of the incisor crowns to the perpendicular drawn to occlusal plane is known as labial inclination.
Occlusal plane is that plane which connects the incisal or biting edge of a central incisor tooth to the occlusal or biting surfaces of the molar teeth.

 Correlation Study Between Mandibular Central Incisor Proclination and Gingival Recession   (Site not responding. Last check: 2007-10-29)
Objective: The purpose of this study was to determine whether proclination of mandibular central incisors during fixed appliance therapy results in gingival recession.
Utilizing pre-treatment and post-treatment lateral cephalograms, the change in mandibular central incisor inclination was measured to divide the patients into an experimental group (proclination) and a control group (no proclination).
Conclusion: It was concluded that the degree of proclination of mandibular central incisors during fixed appliance therapy cannot be correlated to gingival recession in this sample.

Condylar and mandibular central incisor movements [linear distances (LD) and curvilinear pathways (CP)] were recorded in three dimensions for 20 s with an optoelectric (Optotrak®) jaw-tracking system while each participant performed multiple maximum protrusive and lateratrusive cycles.
Incisor movements were only moderately related to condylar movements between individuals and between replicates; LDs showed stronger correlations than CPs; and correlations were stronger for lateratrusion than protrusion.
It was concluded that (1) incisor protrusion and lateratrusion provide moderately reliable measures of condylar translation; (2) the linear distances that the incisors move during lateratrusion provide the best measure of contralateral condylar translation; and (3) condylar movements are not affected by repeated protrusion or lateratrusion.

Clinical and radiological evaluation revealed the cause of the symptoms to be a previously asymptomatic intruded primary incisor on the floor of the nasal cavity.
This case report describes a disfiguring hypoplastic maxillary right central incisor in a 20-year-old man. The maxillary primary central had been traumatized in a fall, which had resulted in its intrusion with subsequent episodes of pain and swelling around the tooth.
An analysis of 191 primary incisors damaged by acute mechanical trauma on 108 children, ranging in age from 2 to 6 years, has showed that most of the patients were between 2 and 3 years of age (67%) when the accidents occurred.

Bleeding from the scaling of the remaining teeth prevented bonding the patient's tooth as a pontic 34-37 to her remaining mandibular anterior teeth as a periodontal splint.
The incontrovertible facts concerning the conservative approach to splinting loose teeth by using enamel bonding with composites and reinforcing fibers is that the enamel is preserved (maintaining strength), pulpal tissue integrity is not violated, and the gingival tissue encroachment is diminished.
She had been previously diagnosed by her family dentist with a chronic periodontal condition in the mandibular anterior region and frenum attachment pull to the soft tissues investing the mandibular central incisor (Figure 1).

The larger tooth fragment appears to be a portion of the maxillary central incisor.
