Effectiveness of lingual versus labial fixed appliances in adults according to the Peer Assessment Rating index.
Introduction: The purpose of this study was to compare the effectiveness of lingual treatment and labial fixed appliances in the treatment of adult orthodontic patients. Methods: We conducted a retrospective study of 72 patients. The Peer Assessment Rating (PAR) index was measured at the start (T0) and end (T1) of treatment. Significant differences between treatment means were determined by means of analysis of variancewith the Bonferroni correction or with the use of Fisher exact test. Results: The lingual group had a mean pretreatment age of 28.6 ± 6.7 years, and the labial group had a pretreatment age of 26.6 ± 9.5 years. This difference was statistically not significant. The mean pre- a…
Effect of saliva contamination on bracket failure with a self-etching primer: A prospective controlled clinical trial
Introduction The aim of this study was to evaluate in vivo the effect of saliva contamination at different stages of the bonding procedure on the bond failure rate and the adhesive remaining on teeth after debonding brackets bonded with a hydrophilic self-etching primer (Transbond Plus self-etching primer [TSEP], 3M Unitek, Monrovia, Calif). Methods This was a prospective controlled clinical trial. The sample consisted of 46 patients with similar treatment plans and mechanotherapies. Stainless steel brackets (n = 531) were bonded with TSEP. The patients were divided into 2 groups: contamination with saliva before TSEP application and contamination with saliva after TSEP application. In both…
A systematic review of the accuracy and efficiency of dental movements with Invisalign®
We are currently living in an era where the use of computer-aided design/computer-aided manufacturing has allowed individualized orthodontic treatments, but has also incorporated enhanced digitalized technology that does not permit improvisation. The purpose of this systematic review was to analyze publications that assessed the accuracy and efficiency of the Invisalign® system. A systematic review was performed using a search strategy to identify articles that referenced Invisalign®, which were published between August 2007 and August 2017, and listed in the following databases: MEDLINE, Embase, Cochrane Library, Web of Knowledge, Google Scholar, and LILACS. Additionally, a manual search o…
Edad de emergencia y secuencias polimórficas de la dentición permanente en una muestra de población de Asturias
Para este estudio sobre edad de emergencia se ha empleado una muestra seccional compuesta por 1.616 individuos del Área II de Asturias con dos objetivos principales. En primer lugar calcular la edad de emergencia de cada diente permanente, con exclusión de los terceros molares. En segundo averiguar la frecuencia de secuencias confrontando cada diente con cada uno de los restantes para detectar la existencia de secuencias polimórficas. Los hallazgos principales indican que la emergencia ocurre más tempranamente en el sexo femenino y que el primer diente en emerger es el I1i y el último el M2s en ambos sexos. Tres secuencias mostraron un dimorfismo sexual significativo. En concreto P2sCi, CiP…
