Caries risk after interproximal enamel reduction.

Introduction: Air-rotor stripping (ARS) is a commonly used method to alleviate crowding in the permanent dentition. Its widespread acceptance, however, has been limited by the potential increase in caries risk of the abraded enamel surface. The aim of this study was to compare the susceptibility of ARS-treated enamel surfaces with intact surfaces in patients undergoing fixed orthodontic therapy.

Accuracy of digital and analogue cephalometric measurements assessed with the sandwich technique.

Introduction: The purpose of the study was to evaluate the accuracy of cephalometric measurements obtained with digital tracing software compared with equivalent hand-traced measurements. In the sandwich technique, a storage phosphor plate and a conventional radiographic film are placed in the same cassette and exposed simultaneously. The method eliminates positioning errors and potential differences associated with multiple radiographic exposures that affected previous studies.

Markers of periodontal infection and preterm birth.

Objective: This study was undertaken to explore the relationship between clinical, microbiologic, and serologic markers of periodontitis and preterm birth (PTB).

Study Design: We compared women with a singleton gestation giving birth before the 37th week (cases, n = 83) with term delivery controls (n = 120). Periodontal examination and collection of dental plaque and blood samples were performed within 48 hours after delivery.

Maxillary canine impactions: orthodontic and surgical management.

With the exception of the maxillary and mandibular third molars, the maxillary canine is the most commonly encountered impaction. In North America, palatally located impactions appear to predominate over labially impacted canines and occur more frequently in women. Because of the common nature of this phenomenon, the general dentist should know how to properly diagnose and manage potential disturbances in the eruption of the maxillary canine.
