Colonization of Streptococcus mutanson esthetic brackets: Self-ligating vs conventional
Introduction Self-ligating orthodontic brackets rely on clips, rather than ligatures, to hold the archwire in place. It is unknown whether replacing ligatures with clips affects the adherence of Streptococcus mutans…
Statistical methods for the assessment of orthodontic materials
Orthodontists use a wide range of materials during patient care; therefore, the performance of the available materials is of great importance. Orthodontic materials are initially tested in the laboratory, and,…

Three-dimensional reproducibility of natural head position
Introduction Although natural head position has proven to be reliable in the sagittal plane, with an increasing interest in 3-dimensional craniofacial analysis, a determination of its reproducibility in the coronal…
Quantitative comparison of 3 enamel-stripping devices in vitro: How precisely can we strip teeth?
Introduction In this in-vitro study, we aimed to investigate the predictability of the expected amount of stripping using 3 common stripping devices on premolars. Methods One hundred eighty extracted premolars…
Tooth whitening in the orthodontic practice: A survey of orthodontists
Introduction The demand for tooth whitening has grown almost exponentially in the last 20 years, but there are no published reports regarding how bleaching is used in contemporary orthodontic practices…
The patient has a big mouth
One of our readers wrote me the following e-mail. Since this month’s issue deals with orthodontic materials, I thought his question would be germane. If a patient swallows some part…

This case report describes the orthodontic treatment of an adult patient with iatrogenic absence of the maxillary canines, moderate maxillary and severe mandibular dental crowding, a Bolton discrepancy with a…
Evaluation of 3 commercially available materials for resolution of white spot lesions
Introduction White spot lesions are often seen on the teeth after orthodontic treatment, resulting in unpleasant esthetics. The aim of this in-vitro study was to compare subjectively and objectively the…
Three-dimensional deformation comparison of self-ligating brackets
Introduction Archwire rotation is used in orthodontic treatment to alter the labiolingual orientation of a tooth. Measurement of the 3-dimensional (3D) motion of the orthodontic brackets requires a new configuration…
