Dynamics of orthodontic root resorption and repair in human premolars: a light microscopy studyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The objective was to examine these processes related to time and root development. Seventy-six premolars were divided into subgroups: 33 teeth were intruded and then extracted (G1); 25 teeth were intruded and then left in situ for varying periods before extraction (G2); 18 teeth served as the controls (G3). All teeth were examined by light microscopy. Using non-parametric statistical analysis, differences between the groups were examined with the Pearson chi-square test. Teeth in G1 and G2 had significantly more resorptive lesions, 55 and 64 per cent, respectively, than the controls of 11 per cent. Resorption was observed ...

Antero-posterior and transverse changes in the positions of palatal rugae after rapid maxillary expansionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The purpose of this study was to investigate the stability of the medial aspects of the rugae in patients where rapid maxillary expansion (RME) was performed in addition to fixed appliance therapy. Nineteen subjects that met the inclusion criteria for each group were randomly selected from the archive of one orthodontist office. The RME/fixed appliances group consisted of 8 males and 11 females (mean age pre-treatment 12.4 ± 2.0 years). The control group treated with fixed appliances only, consisted of 6 males and 13 females (mean pre-treatment age of 12.5 ± 2.1 years). The medial aspects of the rugae were re...

Routine treatment of bilateral aplasia of upper lateral incisors by orthodontic space closure without mandibular extractionsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study aimed to gather statistically validated information on the changes in orthodontic variables in patients with bilateral upper lateral incisor aplasia treated with isolated orthodontic space closure. Data were collected from 25 (15 females, 10 males) consecutively treated, unselected adolescents [mean age at the end of treatment 16.4 years, standard deviation (SD) 1.3] after orthodontic space closure using push-and-pull mechanics (PPM). The changes in the relevant parameters were determined by comparing baseline and final lateral headfilms and casts. Following verification of normal distribution by means of a Kolm...

Pain intensity during the first 7 days following the application of light and heavy continuous forcesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The purpose of the present study was to determine whether a force of 20 cN can be biologically active for tooth movement and to examine the pain intensity during the application of light (20 cN) or heavy (200 cN) continuous forces for 7 days. In the first experiment, a force of 20 cN was applied to eight canines in five volunteers. The mean tooth movement during 10 weeks was 2.4 mm. In the second experiment, two forces of 20 or 200 cN were applied to maxillary premolars in 12 male subjects (aged 24–31 years) to measure pain intensity for 7 days. Spontaneous and biting pain were recorded every 2–4 hours on a 100...

Craniofacial profile in Southern Chinese with hypodontiaEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The association between craniofacial morphology and congenitally missing teeth is at present unclear. The aims of this study were to investigate whether hypodontia is associated with changes in the sagittal skeletal profile and to identify putative relationships between the skeletal profile and the severity of hypodontia. In a cross-sectional analytical study, the craniofacial structure and profile based on two-dimensional lateral cephalograms of Southern Chinese hypodontia patients (n = 49, 24 males, 25 females, mean age 16.4 years) and a comparison group without hypodontia (n = 41, 15 males, 26 females, mean age 16.7 yea...
