Social and psychological concerns, improved function, appearance, self-esteem encourages a patient to pursue Orthodontic treatment, for which extraction may or not be needed. Conventionally steiner stick analysis tweed head plate correction is followed decide during fixed orthodontic treatment desirable outcome. This study was designed compare predicted position angulation of maxillary mandibul...

Results: Maxillary central and lateral incisors and canines typically presented with a single canal of type I canal configuration. In mandibular teeth, most of the central incisors showed type I (57.4%) canal configuration. Type III was found in 37.0% of the cases. The incidence of type III canal configuration in mandibular lateral incisors was 55.9%. The remainder was distributed mainly betwee...

Objective: Dental trauma may occur during daily life because of unexpected accidents. These dental traumas may affect facial esthetics and self-image; thus, successful dental trauma treatment is important. The objective of our study is to determine whether hyaluronic acid (HA) may be used as a stabilizer in the periodontal ligament space of traumatized teeth. Methods: Ex vivo study of pig mandi...

N papers have been pub­ lished on the repair of circumscribed defects in a number of bones of experi­ mental animals (Melcher and Irving 1962; Kramer, Killey and Wright 1968; Agsen 1968). The repair of extraction wounds in the jaws of experimental animals has also been extensively studied (Huebsch et al 1952; Boyne and Kruger 1962; Pietrokovski 1967; Tudo 1968; Huebsch and Hansen 1969; Mesrobia...

BACKGROUND The aim of this study was to present a temporary anchorage device with intraosseous screw for unilateral molar distalization to make a space for the impacted premolar and to found well balanced occlusion in a case. CASE PRESENTATION A 13-year-old male who have an impacted premolar is presented with skeletal Class I and dental Class 2 relationship. The screw was placed and immediate...

In several primate groups enamel is reduced or absent from the lingual (tongue) side of the mandibular incisor crowns akin to other placental and marsupial mammalian groups such as rodents, lagomorphs and wombats. Here we investigate the presumed adaptation of crowns with unilateral enamel to the incision of tough foods in cercopithecines, an Old World monkey subfamily, using a simulation appro...

The change in lower arch crowding 3-4 years after second permanent molar eruption was examined in 85 subjects, in relation to the angulation and change in angulation of molars and incisors relative to the mandibular plane using correlation and multiple regression analyses. Crowding increased significantly during the observation periods. Changes in molar and incisor angulation in both mesial and...

OBJECTIVES The purpose of the present study was to evaluate mandibular talon cusps distribution from the comprehensive literature search and proposal of new classification Material and Methods: The study was a review of articles published in the English language from January 1960 to December 2013. The PubMed/MEDLINE/Google Scholor databases were searched electronically using 'talon cusp', 'dens...

Objective: The objective of this study was to investigate the relationship between age, gender and clinical crown length using a longitudinal study design. Method: Four hundred and fifty-six sets of study models initially obtained for a large prospective longitudinal cohort study of orthodontic needs were examined. Each set of models corresponded to subjects at three different ages: 11–12, 14–1...
