Potential of a New Cone-Beam CT Software for Blooming Artifact Reduction.

This study evaluated the dimensions of intraradicular posts using a new cone beam CT (CBCT) software, and verified the potential of blooming artifact reduction. Sixty-three single-rooted human teeth were shaped, obturated, prepared for intracanal post placement and distributed into three groups: G1: anatomically customized prefabricated glass fiber posts; G2: low-fusion alloy posts; G3: gold alloy posts. After post fabrication and luting with RelyX U200®, specimens were sectioned axially at 9 mm from the root apex, and markings were made on the root surfaces (X-, Y- and Z-axes).

Could orthodontic fixed appliances and excess weight affect gingival health in adolescents?

Introduction: The aim of this study was to evaluate the impact of being overweight or obese while wearing orthodontic fixed appliances on the prevalence of gingivitis in adolescents.

Methods: A total of 334 adolescents, aged between 12 and 18 years, were recruited from 3 public schools in Cuiabá, Brazil. Participants were divided in dichotomized categories of body mass index (BMI) (under and normal weight or overweight and obesity) and fixed orthodontic appliance usage (yes or no).
