Present techniques for predicting eruption or impaction of lower third molars are based on measurements of the space between the second molar and the ramus. This study was designed to investigate the reliability and validity of radiographic techniques often used for assessing this space. Rotational tomograms (O.P.G.s) yielded the best estimates of the Space(More)
INTRODUCTION The goal of this study was to compare the dimensions of maxillary lateral incisors in subjects with and without palatally displaced canines. METHODS An experimental group of 40 patients with 46 palatally displaced canines (20 in boys, 26 in girls; mean age, 13.9 years; range, 10.5-15.9 years) was selected from the records of patients referred(More)
The aim of this study was to determine the feasibility of treating children with impacted maxillary canines by orthodontic treatment alone. The subjects were 28 children (mean age: 13.5 years, range 11.4-16.1 years) with between them 32 palatally impacted canines. The overlying primary canines were extracted between 0 and 42 months before the start of(More)
BACKGROUND Palatally impacted maxillary canines may appear unsightly after treatment because of changes in position and colour. AIM To determine if palatally impacted canines treated either by surgical exposure and orthodontic repositioning or by creation of space in the arch and unassisted eruption have different aesthetic outcomes. METHODS Twenty(More)
BACKGROUND Many palatally impacted canines in children do not require surgical exposure prior to the start of orthodontic treatment. They erupt in mid-alveolar positions providing excess space is made for them in the arch. The time required for an impacted tooth to emerge under these conditions is highly variable. AIM To determine the factors influencing(More)
INTRODUCTION The purpose of this research was to investigate relationships among the location and orientation of palatally displaced canines and the dimension and orientation of the maxillary lateral incisor. METHODS An experimental group of 40 patients with 46 palatally displaced canines (20 from boys, 26 from girls; mean age of the subjects, 13.9 years;(More)
INTRODUCTION In this study, we used Q methodology to assess the concerns of adults seeking orthodontic treatment and to determine individualized interventions to reduce their anxiety. METHODS Statements of concern were derived by in-depth interviews with 70 adult patients. Q sorting methodology was then used to identify the main factors associated with(More)
INTRODUCTION The aim of this study was to investigate the relationships between an apical curvature or a hook and the crown/root ratio in subjects with and without palatally impacted maxillary canines. METHODS An experimental group of 44 patients (17 boys, 27 girls; mean age, 13.6 years) with 59 palatally impacted maxillary canines was selected from the(More)
BACKGROUND Inferior periodontal and pulpal outcomes may follow surgical exposure of palatally impacted maxillary canines. OBJECTIVES To compare the periodontal and pulpal health of palatally impacted maxillary canines following either surgical exposure and assisted eruption (SE) or unassisted eruption following extraction of the overlying deciduous canine(More)
