INTRODUCTION The relationship between malocclusion and quality of life (QoL) is complex and not well understood. The objective of this study was to determine whether malocclusion and its treatment influence an adolescent's general and oral health-related QoL. METHODS An observational, cross-sectional design with a longitudinal component was used. Clinical(More)
INTRODUCTION White spot lesions are a common sequela of orthodontic therapy. In this parallel-group randomized trial, we assessed the effectiveness of 2 agents commonly used to ameliorate white spot lesions compared with a normal home-care regimen. METHODS Patients aged 12 to 20 years were recruited from the offices of orthodontists and dentists who(More)
There are few prospective studies assessing risk factors for onset of temporomandibular (TMD) pain disorders in any age group. The aim of this prospective cohort study was to identify risk factors for onset of clinically significant TMD pain (i.e., pain meeting research diagnostic criteria for myofascial pain and/or arthralgia) during early adolescence.(More)
Fifty-one patients were enrolled in this study to explore the treatment effects of material stiffness and frequency of appliance change when using clear, sequential, removable appliances (aligners). Patients were stratified based on pretreatment peer assessment rating (PAR) scores and need for extractions. They were randomized into 4 treatment protocols:(More)
INTRODUCTION Self-ligating brackets have been gaining popularity over the past several decades. Various advantages for these systems have been claimed. The purposes of this systematic review were to identify and review the orthodontic literature with regard to the efficiency, effectiveness, and stability of treatment with self-ligating brackets compared(More)
BACKGROUND Orthodontic therapy has been suggested to lead to an improved periodontal status through mechanisms such as increased ease of plaque removal and reduced occlusal trauma. The objective of the authors' systematic review was to compare contemporary orthodontic treatment with no intervention, by means of evaluating periodontal outcomes measured after(More)
OBJECTIVE To determine whether there was a difference between planned home births and planned hospital births in Washington State with regard to certain adverse infant outcomes (neonatal death, low Apgar score, need for ventilator support) and maternal outcomes (prolonged labor, postpartum bleeding). METHODS We examined birth registry information from(More)
Recent advances in technology have led to the availability of sequential removable orthodontic appliances (aligners) to move teeth in a stepwise fashion (Invisalign, Align Technology, Santa Clara, Calif). This study was undertaken to compare 2 distinctly different materials (hard and soft) and 2 activation frequencies (1 week and 2 weeks) for this(More)
The records of 33 openbite patients treated with cribs were collected. The sample was divided into two groups with group one comprised of 26 growing patients and group two comprised of seven nongrowing patients. There was a significant increase in overbite for both groups during treatment. The nongrowing group also showed a significant increase in overbite(More)
INTRODUCTION Facial profile disharmonies in the anteroposterior (AP) position of the mandible are among the most frequent reasons that patients seek orthodontic treatment. Various methods are available for assessing profile preferences, and differences between them could affect treatment decisions. The purposes of this study were to compare and contrast 3(More)
