Randomized Controlled Trial Multicenter StudyA randomized clinical trial comparing the efficacy of ibuprofen and paracetamol in the control of orthodontic pain.
Previous research has shown that ibuprofen provides effective relief from orthodontic pain. The aim of this study was to ascertain whether paracetamol (also known as acetaminophen) provided pain relief of equivalent or greater magnitude. ⋯ A combination of preoperative and postoperative ibuprofen is more effective than paracetamol in the control of orthodontic pain.

Structured abstracts: do they improve the quality of information in abstracts?
This retrospective observational study was designed to assess the impact on quality of changing from unstructured to structured abstract format. Six dental journals, 3 that adopted structured abstracts and 3 with unstructured abstracts, were used. ⋯ Structured abstracts provide higher-quality information. Journal editors should be encouraged to use a structured abstract format.

Sagittal, vertical, and transverse changes consequent to maxillary molar distalization with the pendulum appliance.
The purpose of this study was to evaluate the skeletal and dental changes in patients who underwent distalization of their maxillary molars with pendulum appliances. ⋯ The pendulum appliance is effective for distalization of the maxillary molars and the establishment of a Class I molar relationship in a relatively short time. However, caution is needed to control collateral effects, including mesial movement of the first premolars and distal tipping of the molar crowns.

Dentoalveolar and skeletal changes associated with the pendulum appliance followed by fixed orthodontic treatment.
This prospective clinical study analyzed the distalization of maxillary molars achieved by the pendulum appliance and its effect on the anchorage teeth during and after fixed orthodontic treatment. ⋯ The pendulum appliance followed by fixed orthodontic treatment corrected the Class II sagittal relationship, especially due to the dentoalveolar changes secondary to the spontaneous mandibular growth in the anterior direction during fixed appliance treatment.
