Polishing after the removal of brackets is the final step in orthodontic treatment. It is simple to perform, though some studies have reported that polishing causes damage to the enamel surface. An in vitro study was made of the influence of the buccal surface convexity of the tooth upon possible enamel loss when the remaining resin and adhesive are removed after bracket decementing using two different polishing modes: a tungsten carbide bur at low and high speeds. The convexity of the buccal surface was quantified in 30 incisors and 30 premolars...

BACKGROUND: This study aims to investigate the impact and safety of combining maternal voice stimulation with gravity feeding on low-birth-weight preterm infants. The research focuses on key outcomes such as gastric tube indwelling time, feeding transition time, adequate gastrointestinal nutrition time, recovery of birth weight time, length of hospital stay, and oral motor function in preterm infants. METHODS: A total of 150 low birth weight preterm infants meeting inclusion criteria were recruited from the neonatal care unit and randomly assigned to three groups: traditional nasal feeding, gravity feeding with a homemade bracket, and a combined group receiving both gravity feeding and maternal voice stimulation...

BACKGROUND: Alopecia is a chronic dermatological disorder affecting men and women worldwide. Given the high incidence and significant impact on patients' well-being, options for managing and treating alopecia are essential.

Objective: This article aims to review the safety and efficacy of the Er:YAG laser in debonding dental accessories. Methods: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Articles published between 2010 and 2022 on the removal of dental accessories using erbium laser were searched. The selected articles were then classified according to the accessories used: adhesives, brackets, restorations, or implant crowns. Enamel surface roughness, shear bond strength, adhesive remnant index, duration time (t), pulp chamber temperature (T), morphology (M), and other variables were then noted...

Herein, we present a new method for determining the Ca isotopic composition of geological samples. To eliminate matrix elements from Ca, a column chromatography method was developed using a N , N , N ' N ' tetraoctyl-1,5-diglycolamide (TODGA) resin. The Ca isotopic compositions were measured by a multiple collector inductively coupled plasma mass spectrometry (MC-ICP-MS) without collision cell equipment, especially that direct measurement to 44 Ca/40 Ca can be achieved. To mitigate the interference from 40 Ar during 40 Ca measurement, the cold plasma technique was used to suppress the Ar+ generation, resulting in a background Ar+ intensity of <300 mV, in contrast to the conventional hot plasma conditions, which typically yield thousands of volts for Ar+ intensities...

Biofilm formation is a common concern during orthodontic treatment, as it can lead to oral health issues. MATERIALS AND METHODS: The study utilized a randomized controlled trial design. The participants were divided into two groups: the experimental group and the control group. The experimental group received orthodontic brackets coated with nanoparticles, while the control group received regular brackets...

BACKGROUND: Acid etching enamel improves resin-enamel adhesion and adhesive characteristics, but has pros and cons. The effects of laser etching on the bonding of orthodontic brackets vary depending on the wavelength, power output, exposure duration, and energy delivered. MATERIALS AND METHODS: This study used a new 1064-nm diode laser to irradiate 30 freshly extracted human premolars. They were divided into three groups: group A, group B, and group C. Acid etching was used for 1 min to bond bracket to tooth surface, and Indian ink was used for 30 s...

INTRODUCTION: Numerous manufacturers have improved bracket retention systems as a result of the frequent bond failure that occurs during orthodontic treatment. One of the elements affecting the adhesive's bond strength is the bracket retention mechanism. OBJECTIVES: This study's objective was to assess how various bracket base retention characters affected shear bond strength. MATERIALS AND METHODS: Four distinct base features for brackets were evaluated...

INTRODUCTION: The esthetic during the various orthodontic treatments has led to the invention of the brackets. When different ceramic brackets and archwires are used, the different frictional forces may result in the different outputs. Hence, in the present study, we evaluated and compared the frictional resistance between eight standard monocrystalline ceramic bracket models and each of the archwires of four different alloys. MATERIALS AND METHODS: Frictional force was tested using Instron testing machine, in vitro , for eight types of monocrystalline ceramic bracket, and four types of archwires beta-titanium, NiTi, copper-nickel-titanium, and stainless steel statistical analysis were done using various tools, and significance value of <0...

Therefore, seven brackets systems were evaluated in conjunction with different stainless steel archwires of varying dimensions (0.016″ × 0.022″, 0.018″ × 0.025″, and 0.019″ × 0.025″). Biomechanical behavior during torque development and transmission was assessed using a six-component force/torque sensor...

Orthodontic treatment during adolescence can contribute to the development of problematic eating disorders. This case study presents the situation of a 12-year-old male patient who experienced a prolonged period of dietary limitation, showed signs of chronic illness, and underwent a significant weight loss because of wearing dental braces. These circumstances triggered the emergence of atypical eating behaviors and complicated the therapeutic process. A case report highlights the effectiveness of conducting psychological evaluations for patients with braces who experience significant weight loss to address possible eating disorders...

Aim This study aims to examine five mandibular parameters: coronoid ramus height, condylar ramus height, projective ramus height, minimum ramus breadth, and gonial angle, using orthopantomography (OPG). Introduction The mandible, a crucial part of the human skull, demonstrates sexual dimorphism, which makes it an important tool for determining sex in forensic and anthropological investigations. Its form and structure are relatively resistant to significant changes after death. Among all skeletal components, the mandible stands out as a primary indicator of sexual differences...
