Transferring the tooth preparation finish line on intraoral digital scans to dental software programs: A dental technique.

Intraoral scanner software programs allow the clinician to draw the tooth preparation finish lines. However, this information may be lost when importing the digital file into different computer-aided design (CAD) dental software programs. A technique for transferring the marked tooth preparation finish line into an intraoral digital scan is described.

Effects of Photobiomodulation on the Upper First Molar Intrusion Movement Using Mini-Screws Anchorage: A Randomized Controlled Trial.

The aim of this study was to quantify the changes obtained when the molar intrusion movement is complemented by photobiomodulation (PBM). A common problem in adult patients is the super-eruption of maxillary molars caused by the loss of the antagonist tooth. Super-erupted molars impair oral rehabilitation and can cause both occlusal and functional problems.

Impact of photodynamic therapy versus ultrasonic scaler on gingival health during treatment with orthodontic fixed appliances.

Objectives: Poor oral hygiene during treatment with fixed appliances results in plaque accumulation. The presence of bacteria in the gingival crevice triggers an inflammatory reaction in the gingival tissues. The aim of this study was to compare the impact of two preventive treatments, photodynamic therapy (PDT), and ultrasonic scaler (US), on gingival health in patients under fixed orthodontic treatment.

Efficacy of photodynamic therapy vs ultrasonic scaler for preventing gingival inflammation and white spot lesions during orthodontic treatment.

Introduction: The complex designs of fixed orthodontic appliances hinder proper access for cleaning, favouring the development of gingival inflammation and white spot lesions around brackets. The aim of this study was to evaluate the effectiveness to avoid these undesirable effects by using two prophylactic methods: Photodynamic Therapy (PDT) and conventional ultrasonic scaler (US), in patients during fixed orthodontic treatment.

Materials And Methods: Twenty patients under orthodontic treatment for at least 15 months were randomly divided into two groups: PDT mediated by methylene blue (MB) and US.

Clinical and microbiological effects of the use of a cetylpyridinium chloride dentifrice and mouth rinse in orthodontic patients: a 3-month randomized clinical trial.

Objective: To assess the clinical, microbiological, and patient-based effects of using a cetylpyridinium chloride (CPC) toothpaste and mouth rinse in orthodontic patients.

Design: Parallel randomized controlled, triple-blinded trial (participants, examiners, outcomes' assessors). A computer-generated list was used to allocate treatments.

On-line laser radiation controlled to the removal of adhesive on teeth after bracket debonding.

Background And Aims: After bracket debonding a correct removal of the adhesive from tooth surfaces without causing any iatrogenic damage to the enamel is needed. However, conventional techniques do not allow a selective removal process. The present article focuses on the removal of adhesive on teeth after bracket debonding by using laser radiation at 355 nm (third harmonic wavelength of a Q-switched Nd:YAG).

Impact of delayed gratification on oral health and caries status in the primary dentition.

Objective: The ability to delay gratification (ATDG) is naturally linked to key regulatory psychological traits involved in self-discipline/regulation. The aim of this study was to ascertain the normalized impact of ATDG as an early predictor of oral health, on the primary dentition.

Methods: 404 subjects [202 children (4-6 years old) and 202 mothers] were enrolled in a case-control study.

Short- and Medium-Term Effects of Low-Level Laser Therapy on Periodontal Status in Lingual Orthodontic Patients.

Objective: The purpose of this study was to evaluate the short- and medium-term effects of low-level laser therapy (LLLT) applied in repeated doses in adults with a healthy periodontium treated by lingual orthodontic appliances.

Background Data: Plaque accumulation, in combination with difficulty in removing it in lingual orthodontic patients, can cause gingival inflammation.

Methods: Twelve orthodontic patients scheduled for fixed lingual orthodontic treatment were selected.

Long-term stability of rapid maxillary expansion combined with chincup protraction followed by fixed appliances.

Objective: To analyze the long-term stability of rapid maxillary expansion (RME) and protraction from chincup therapy in girls with Class III malocclusion.

Materials And Methods: Twenty-two girls (mean age  =  9.1 ± 0.

Effects of low-level laser therapy on orthodontics: rate of tooth movement, pain, and release of RANKL and OPG in GCF.

The aim of the study was evaluate tooth movement, receptor activator of nuclear factor KB ligand (RANKL), osteoprotegerin (OPG), and RANKL/OPG ratio in gingival crevicular fluid (GCF) in compression side and pain level during initial orthodontic tooth treatment to determine the efficacy of low-level laser therapy (LLLT). Ten volunteers who required fixed appliance positioned from the upper first premolars to upper first molars were selected. For each patient, the upper first premolar of the quadrant 1 was chosen to be irradiated with a laser diode at 670 nm, 200 mW, and 6.

Longitudinal evaluation of sEMG of masticatory muscles and kinematics of mandible changes in children treated for unilateral cross-bite.

The aim of this study was to evaluate masticatory muscle activity and kinematics of mandible changes in children with unilateral posterior cross-bite (UPXB) after orthodontic treatment, and one year after retention. Twenty-five children with UPXB and functional mandibular shift were evaluated before treatment (mean age 12.5years), after treatment (mean age 14.

A new concept of anatomic lingual arch form.

Introduction: The aim of this study was to describe a natural and anatomic lingual arch form obtained from subjects with normal occlusion that could be used, with other criteria, in the construction of personalized setups for the lingual straight-wire technique.

Methods: The study sample comprised 58 pairs of dental casts of the arches of 58 southern Europeans (37 women, 21 men) with ideal natural occlusions. After the reference points of the dental arches were identified and marked, the dental casts were scanned.

Activity of jaw muscles in unilateral cross-bite without mandibular shift.

Objectives: To evaluate and compare electromyographic activity of jaw muscles at rest and during maximal voluntary clenching in maximal intercuspation between growing individuals with unilateral posterior cross-bite without functional mandibular lateral shift during closure and matched individuals with normal occlusion. These findings may help elucidate the impact of this occlusal condition on jaw muscle function and the therapeutic implications.

Design: 30 growing children (10-12 years) with unilateral cross-bite without functional mandibular lateral shift during closure (cases) and 30 age- and sex-matched children with normal occlusion (controls) were consecutively selected applying highly restrictive criteria.

[Risk factor control and treatment of atherothrombosis. Spain REACH Registry].

Background And Objective: The REACH Registry is the largest worldwide registry designed to obtain information on cardiovascular risk factor control and preventive treatment in a population who have, or are at high risk of having, symptoms of atherothrombosis. The objective of this study is to show the results obtained in a sample of the Spanish population included in that registry.

Patients And Method: Registry of consecutive patients who have risk factors only (RFO) for atherothrombosis or who have symptomatic vascular disease (VD): coronary heart disease (CHD) and/or cerebrovascular disease (CVD) and/or peripheral artery disease (PAD).

Skeletal maturation determined by cervical vertebrae development.

The aim of this study was to determine the validity of cervical vertebrae radiographic assessment to predict skeletal maturation. Left hand-wrist and lateral cephalometric radiographs of 958 Spanish children from 5 to 18 years of age were measured. On the left hand-wrist radiographs the classification of Grave and Brown was used to assess skeletal maturation.
