Analysis of the Frequency and Correlated Factors of Midpalatal Suture Maturation Stages in Young Adults, Based on Cone Beam Computed Tomography Imaging.

Background: The choice of whether to perform a palatal disjunction in constricted maxilla has traditionally been decided based on the age of the patients, although there are gradually increasing references to the fact that this is not a determining factor. The main goal of this study was to evaluate the frequency of the different stages of midpalatal suture maturation in a sample of young adults between 15 and 30 years of age. Other objectives also included analyzing the possible correlation the maturation stages could maintain with sex and age groups.

Skeletal, Dentoalveolar and Dental Changes after "Mini-Screw Assisted Rapid Palatal Expansion" Evaluated with Cone Beam Computed Tomography.

The purpose of this study was to evaluate skeletal, dentoalveolar and dental changes after Mini-screw Assisted Rapid Palatal Expansion (MARPE) using tooth bone-borne expanders in adolescent patients after analyzing different craniofacial references by Cone beam computed tomography (CBCT) and digital model analysis. This prospective, non-controlled intervention study was conducted on fifteen subjects (mean age 17 ± 4 years) with transversal maxillary deficiency. Pre (T1) and post-expansion (T2) CBCTs and casts were taken to evaluate changes at the premolars and first molar areas.

Knowledge of First Aid Measures in Dental Trauma: A Survey of Teachers in the Province of Seville, Spain.

The high incidence of childhood dental trauma requires childcare professionals to have basic notions of dental first aid. The aim of this study is to assess the level of knowledge and aptitude (defined as the ability to operate competently in a given activity) of early childhood, primary, and/or secondary education teachers from Seville (Spain) referred to first aid measures in dental trauma. A descriptive study was conducted.

Efficacy and predictability of maxillary and mandibular expansion with the Invisalign® system.

Background: The purpose of this study is to evaluate the efficacy and predictability of upper and lower orthodontic expansion with the Invisalign® system.

Material And Methods: From a sample of 167 patients; 64 upper and 51 lower arches were randomly selected from patients who had been treated with plastic orthodontics (Invisalign® aligners, SmartTrack® material). Digital models were extracted at the beginning (ModT1) and at the end of treatment (ModT2) as well as the final ClinCheck® (CkT2).

Canine transposition as an alternative to trauma of the maxillary incisors: case report.

Objective: The present article aims at reporting the clinical case of a patient who suffered trauma at two years of age, causing almost complete apical displacement of the deciduous maxillary left central incisor and of the permanent incisor.

Methods: Ectopia secondary to intrusion was minimized by surgical removal of the ectopic tooth, and the left permanent canine was submitted to orthodontic traction to replace the extracted tooth.

Results: The treatment period lasted 36 months, resulting in correct occlusion and a good aesthetic outcome.

Clinical and radiographic evaluation of white MTA versus formocresol pulpotomy: A 48-month follow-up study.

Purpose: To determine whether there were differences between formocresol (FC) and white mineral trioxide aggregate (MTA) pulpotomy in terms of clinical and radiographic signs or effects upon the permanent successor over a long term.

Methods: A total of 212 molars (74 treated with FC and 138 with white MTA) corresponding to 129 subjects [66 females (51.1%) and 63 males (48.

Effect of mineral trioxide aggregate (MTA) pulpotomies in primary molars on their permanent tooth successors.

Purpose: To determine the long-term success rate of white MTA pulpotomies in primary teeth and its influence upon eruption and calcification of the permanent successor, as well as other key clinical and radiographic parameters.

Methods: A total of 138 molars from participants between 2-10 years of age were included. Clinical and radiographic parameters were monitored in the primary and/or permanent successor at 6, 12, 18, 24, 30, 36, 42, and 48 months or until eruption of the permanent successor, using the contralateral tooth as control.
