Relationship between dental crowding and mandibular incisor proclination during orthodontic treatment without extraction of permanent mandibular teeth.

Objective: To examine changes in mandibular incisor proclination and protrusion resulting from alleviation of crowding.

Materials And Methods: Records of 96 patients from a private practice treated without extractions or interproximal enamel reduction in the mandibular arch were included. Pre- and post-treatment cephalograms and models were examined to determine changes in incisor proclination, protrusion and crowding.

Acrylic orthodontic retainer is not a risk factor for focal Candida colonization in young healthy patients: a pilot study.

Background: Denture enhances the risk of Candida colonization because of adherence to acrylic base and interference with salivary rinsing. Acrylic orthodontic appliances may also create retentive areas for food debris and microbial pathogens; moreover, patients are instructed to use the retainers at night, when salivary secretion is reduced. We studied the Candida colonization in orthodontic patients using acrylic retainer.

Can black extrinsic tooth discoloration predict a lower caries score rate in young adults?

Objective: The aim of this study was to examine the association between black extrinsic tooth discoloration and caries prevalence in an adult population. This association has been previously shown in children and adolescents but has never been examined in an adult population.

Method And Materials: Young adults, aged 18 to 29 years old, were examined for black extrinsic tooth discoloration and caries prevalence.

[Orthodontic fixed retainer: fix or not fix? that is the question].

Orthodontic fixed retainer is widely used, as an orthodontic retention appliance, for nearly four decades. It answers the need for prolonged retention with minimum patient compliance. The effectiveness of fixed retainers was compared to other retention devices in several studies, and was found as effective as removable appliances.

[Are you afraid of open bite?].

Treatment of open bite malocclusion is a challenge for both the orthodontist and the patient. The key to successful treatment are careful evaluation, that leads to correct diagnosis and treatment plan, as well as meticulous cooperation on behalf of the patient. There are many treatment options starting with follow up and orofacial myofunctional therapy, and concluding with orthosurgical correction.

Case report on trial: Do you, Doctor, swear to tell the truth, the whole truth and nothing but the truth?

We are in the era of "evidence based medicine" in which our knowledge is stratified from top to bottom in a hierarchy of evidence. Many in the medical and dental communities highly value randomized clinical trials as the gold standard of care and undervalue clinical reports. The aim of this editorial is to emphasize the benefits of case reports in dental and oral medicine, and encourage those of us who write and read them.

Occlusal patterns in patients with idiopathic scoliosis.

Introduction: Idiopathic scoliosis is an orthopedic condition characterized by faulty posture. It might also be associated with some mild forms of facial asymmetry or dental deviations. The aim of the study was to clinically examine the occlusions of patients with idiopathic scoliosis.

Prediction of premolar tooth lengths based on their panoramic radiographic lengths.

Objective: Establishing a linear regression model for the determination of first premolar lengths based on panoramic radiographs.

Materials And Methods: The real lengths of 112 first premolars extracted for orthodontic reasons were measured and compared with their panoramic lengths. The teeth were divided into four groups according to their intraoral quadrant locations (T14, T24, T34, T44) and regression analysis was conducted for each group.

Dynamics of tissue changes found after mechanical loading of the rat incisor. I. A three-dimensional longitudinal study of the morphologic aspects.

A three-dimensional morphometric method was used to evaluate progressive changes in shape and size of recovering dental and periodontal tissues after orthodontic loading. In 35 female rats weighing 212 +/- 4 gm, loads of 19.7 +/- 1.
