Reliability and accuracy of Artificial intelligence-based software for cephalometric diagnosis. A diagnostic study.

Background: Artificial intelligence (AI) is revolutionizing cephalometric diagnosis in orthodontics, streamlining the patient assessments. This study aimed to assess the reliability, accuracy, and time consumption of artificial intelligence (AI)-based software compared to a conventional digital cephalometric analysis method on 2D lateral cephalogram.

Methods: 408 lateral cephalometries were analysed using three methods: manual landmark localization, automatic localization, and semi-automatic localization with AI-based software.

Esthetic comparison of two composites used for Invisalign's attachments bonding.

Background: Esthetics is a factor of great importance for most patients undergoing treatment with Invisalign® aligners. When choosing a resin composite for the bonding of attachments required for the treatment, ideal characteristics such as low visibility and stain resistance of the material are essential to increase the overall perceived esthetics of the treatment. The objective of this article was to evaluate the esthetics of two resin composites used for attachment reproduction: the Transbond XT® from 3M® and the Tetric EvoCeram® from Ivoclar Vivadent®.

A comparison of the upper anterior teeth movements with optimized and conventional attachment.

Background: Invisalign® attachments are divided into two main groups: the conventional group and the optimized group, which is also known as the SmartForce™. The aim of this study is to compare the movements produced by an optimized crescent-shaped attachment in superior incisor teeth with the movements produced by a conventional rectangular attachment (vertical and horizontal) in the same teeth.

Material And Methods: This retrospective study examined the movement table of the initial ClinCheck® and the first refinement of 95 patients (mean age 44.

Effects of non-nutritive sucking habits on malocclusions: a systematic review.

The development of the craniomandibular system is guided by genetic interactions and environmental factors, including specific habits such as breastfeeding, bottle feeding, thumb sucking and the use of pacifiers. These habits can have a considerable impact on the growth of the developing jaws and can lead to malocclusion in children. This review aims to investigate potential associations between non-nutritive sucking habits (NNSHs) and malocclusions compared to the presence of nutritive sucking habits (NSHs).

Emergency appointments and psychological distress during COVID-19 lockdown among orthodontic patients in Spain.

Background: COVID-19 created an unexpected situation for dental patients. However, the impact of the lockdown on orthodontic patients is still unknown. Hence, this study was conducted to analyse the number and type of emergencies, distress and fear of getting infected among brackets and aligners orthodontic patients during the COVID-19 lockdown.

Influence of social media on the esthetic perception of the lip profile of orthodontic patients.

Objective: To identify the use of social media as an influencing factor of the orthodontic patient's preferences regarding the lip profile protrusion.

Methods: A two-part cross-sectional questionnaire was distributed to orthodontic patients in Spain and The Netherlands. The first part collected general data and frequency of use of different social media.

Air particulate concentration during orthodontic procedures: a pilot study.

Background: This study evaluates the particle dispersion involved in dental procedures carried out during orthodontic treatments. Variants such as temperature and relative humidity in the dental cabinet were considered.

Methods: Using a particle counter, a pilot study was conducted, in which 98 consecutive recordings were made during appointments of patients undergoing orthodontic treatments.

Prevalence of Hypodontia in a Sample of Spanish Dental Patients.

Objectives: The aim of this retrospective study was to evaluate the prevalence of hypodontia in a sample of dental patients, aged between seven and eleven years at University Alfonso X in Madrid (Spain).

Materials And Methods: The number of hypodontia cases and the most affected teeth were evaluated in 2500 panoramic radiographs in a random sample of dental patients consisting of 1235 females and 1265 males. We divided them according to age, number of hypodontia present in each patient (multiple or single), each side, each quadrant either in the upper jaw or in the mandible.

Visual perception of skeletal class and biotype in Spain.

The aim of this study was to determine and compare the visual accuracy of students and experienced orthodontists in distinguishing the different skeletal classes and facial biotypes using only lateral photographs. A group of 19 orthodontic students (4 males and 15 females, aged between 23 and 30 years) and 9 experienced orthodontists (three males and six females, aged between 30 and 56 years) were shown a slide presentation of 100 (50 males and 50 females) patients aged between 8 and 42 years and were asked to indicate the skeletal class and the facial biotype of each subject. Data were analysed using a one-way repeated measures analysis of variance, with Bonferroni post hoc adjustment for multiple testing.
