Factors Associated with Orthodontically Induced Apical Root Resorption of Maxillary Incisors
… measuring RR of right and left maxillary central incisors. Using </p> <p>fiduciary markers at the anterior nasal spine (ANS), posterior nasal spine (PNS), and nasion (Na), movement of the incisors were assessed at three dental landmarks, the incisal edge (I), the center of resistance (C), and the …

AP Relationship of the Maxillary Central Incisors to the Forehead in Adult Korean Females
… relationship of the maxillary central incisors to the forehead in adult Korean females with harmonious profiles and in adult Korean female orthodontic patients. Methods: Ninety five photographic images of adult Korean females with good facial harmony (control group) were compared with …

Survival rate and fracture strength of maxillary incisors, restored with different kinds of full veneers : an in-vitro study
In this study, the survival rate and fracture strength of different kinds of ceramic full veneers, fabricated with a new experimental press ceramic (EPC), were evaluated after exposure to the artificial mouth. <br>Eighty, caries-free human maxillary central molars were used as abutments for the …

A Radiographic Analysis of Variance in Lower Incisor Enamel Thickness
… help predict the enamel thickness of mandibular incisors. At least two direct digital periapical radiographs were made for each of the 80 subjects. Radiographs were scaled to control for magnification errors using dental study models and computer software. Mesiodistal incisor width and mesial and …

The Effect of Orthodontic Treatment on Sagittal Root Position of the Maxillary Central Incisor
… Sagittal root position (SRP) of maxillary incisors is an important factor in implant treatment planning. Kan et al defined four classes of SRP in an effort to aid implant placement treatment planning and these SRP classifications represent a novel approach to describing bone changes around …

Survival rate and fracture strength of endodontically treated crowned maxillary incisors with severe defects, restored with different post and core systems after exposure to the artificial mouth.
Sixty-four caries-free maxillary incisors were randomly selected for similar size and quality prospectives, were endodontically treated and received a 1.2 mm circular shoulder preparation with a subjective convergence angle of 6°. The crown was cut off 2 mm above the cemento-enamel junction. The …

Maxillary Incisor Crown Form and Crowding in Adolescent Orthodontic Patients
… <em>anatomical</em> crown form of the maxillary incisors, as measured from the cementoenamel junction (CEJ), in relation to crowding. The aim of this study was to evaluate the statistical association between maxillary incisor crown form and the extent of crowding in adolescent boys and girls who …

Treatment Outcomes and Stability in Extraction vs. Non-Extraction Adult Anterior Open Bite Patients
… in achieving positive overbite of both central incisors when treating with (97%) or without extractions (92%). No clinically significant differences in skeletal outcomes were observed. The extraction group exhibited more lingual tipping and posterior movement of maxillary and mandibular incisors …

Tratamento ortodôntico de pacientes com agenesia de incisivos laterais superiores
… followed by lower premolars, maxillary lateral incisors and upper premolars. The treatment of dental agenesis of maxillary lateral incisors may consist in closing the space by orthodontic movement added to a new anatomy form of the canine and the first premolar. Another option of treatment is …

Changes of the Marginal Periodontium as a Result of Labial Tooth Movement in Monkeys
… and orthodontic forces were applied. The central incisors were moved labially a mean distance of 3.05mm. Post therapy measurements were performed to assess the change which occurred as a result of tooth movement. Significant recession of the gingival margin, connective tissue level and marginal …

Consequences of Contact: An Evaluation of Childhood Health Patterns Using Enamel Hypoplasias Among the Colonial Maya of Tipu
… 0.36 more episodes than maxillary central incisors. 79.3% of central incisors were affected and 87.3% of canines displayed lesions. Individuals dying as younger adults had significantly more episodes than older adults. Only a slight difference between means and individual tooth frequencies …

The influence of the interaction of fluoride (F) and aluminum (Al) on bioavailability in bacterial and mammalian systems
… rabbits. Fluoride accumulation in plasma, urine, incisors and tibia was increased as the F addition to the drinking water increased within groups receiving a single concentration of Al. In contrast, F accumulation in plasma, urine, incisors and tibia decreased as the Al concentration increased …

Pain Threshold of Human Anterior Teeth to Pressure Stimulation
… threshold level of adolescent maxillary central incisors is higher than maxillary lateral incisors. Additionally, it is obvious that the many variables which affect pain threshold are easier to control when tests are performed on the same day than when performed on different days. Further studies …

A proof of concept to differentiate among differences in flavor of American lamb using volatile flavor compound analysis
… 3 dentition groups [ young lambs (0 permanent incisors), yearlings (2 permanent incisors) and mature sheep or mutton (>2 permanent incisors)] to establish a proof of concept for differentiating the inherent differences in flavor that exist in meat from ovine animals of various age classes using …

Putting teeth into the developmental origins hypothesis: A longitudinal study of early childhood malnutrition, enamel hypoplasia and adolescent health in Amazonian Bolivia
… 2015, we examined EH in the permanent maxillary incisors and mandibular canines using digital photography from which the following measures of EH were abstracted: occurrence (any, none), extent of occurrence (<1/3, 1/3-2/3, >2/3 of the tooth surface) and estimated age at occurrence (1, 2, 3, 4 …

CBCT Evaluation of Morphological Changes to Alveolar Bone Due to Orthodontic Tooth Movement
… the orthodontic movement of the mandibular incisors, and awareness of this structural limitation may reduce the risk of potential damage to tooth roots and alveolar bone. A decision regarding the correct placement of the lower incisors will be largely determined by the amount of adaptation …
