ANCOVA is a method that can be thought of as a cross between ANOVA and Regression, and is, in fact, an A NOVA where the effects of some other variable have been controlled for statistically. Expand
Self-ligating vs conventional brackets in the treatment of mandibular crowding: a prospective clinical trial of treatment duration and dental effects.
Overall, no difference in the time required to correct mandibular crowding with Damon 2 and conventional brackets was observed, and the self-ligating group showed a statistically greater intermolar width increase than the conventional group. Expand
Collinearity in a regression framework refers to the situation where one of the columns of the design matrix is linearly dependent on other columns. Expand
Effectiveness of non-conventional methods for accelerated orthodontic tooth movement: a systematic review and meta-analysis.
There is some evidence that low laser therapy and corticotomy are effective, whereas the evidence is weak for interseptal bone reduction and very weak for photobiomodulation and pulsed electromagnetic fields. Expand
External apical root resorption in patients treated with conventional and self-ligating brackets.
Age, sex, and extraction treatment were not reliable predictors of EARR, but a positive association between EARR and duration of treatment was observed and no difference should be expected for root resorption between conventional and passive self-ligating brackets. Expand
Failure rate of self-ligating and edgewise brackets bonded with conventional acid etching and a self-etching primer: a prospective in vivo study.
Bonding of self-ligating brackets with SEP does not demonstrate higher probability for failure relative to standard bonding procedures and conventional brackets, and no difference in failure incidence was noted for either bracket-adhesive and mandibular or maxillary arch combinations, whereas a statistically significant difference was shown for right-sided appliances.

Torque expression of self-ligating brackets compared with conventional metallic, ceramic, and plastic brackets.
The ceramic bracket (Fascination 2) presented the highest torquing moment and, together with a SS bracket, the lowest torque loss (4.6 degrees), and self-ligating, polycarbonate, and selective metallic brackets demonstrated almost a 7-fold decreased moment developed during insertion of a 0.019 x 0.022-inch slot and a 100 per cent increase in loss.

How long does treatment with fixed orthodontic appliances last? A systematic review.
Based on prospective studies carried out in university settings, comprehensive orthodontic treatment on average requires less than 2 years to complete. Expand
Long-term periodontal status of patients with mandibular lingual fixed retention.
The results of this study raise the question of the appropriateness of lingual fixed retainers as a standard retention plan for all patients regardless of their attitude to dental hygiene and emphasize the importance of individual variability and cautious application of retention protocols. Expand
Active or passive self-ligating brackets? A randomized controlled trial of comparative efficiency in resolving maxillary anterior crowding in adolescents.
The use of passive or active self-ligating brackets does not seem to affect treatment duration for alleviating initial crowding and higher irregularity index values were associated with the increased probability of delayed resolving of crowding. Expand
