1. Failure rates of miniscrews inserted in the maxillary tuberosity
RESUMO Introdução: a manutenção da ancoragem sempre foi um desafio na Ortodontia. Objetivo: o objetivo do presente estudo foi descobrir a taxa de falhas dos mini-implantes instalados na região da tuberosidade maxilar (TM). Métodos: o presente estudo piloto avaliou 40 pacientes (23 mulheres, 17 homens; idade média = 20,1 ± 8,9 anos) que receberam

2. Effect of different stripping techniques on pulpal temperature: in vitro study
RESUMO Introdução: o desgaste proximal do esmalte é um procedimento clínico rotineiro utilizado na Ortodontia para se criar espaços ou equilibrar discrepâncias de tamanho dentário. Esse procedimento pode resultar em transferência de calor para a polpa, predispondo-a a mudanças histopatológicas e necrose do tecido pulpar. Objetivo: medir as mudan

3. High-intensity laser application in Orthodontics
ABSTRACT Introduction: In dental practice, low-level laser therapy (LLLT) and high-intensity laser therapy (HILT) are mainly used for dental surgery and biostimulation therapy. Within the Orthodontic specialty, while LLLT has been widely used to treat pain associated with orthodontic movement, accelerate bone regeneration after rapid maxillary expansion, an

4. Frictional resistance of self-ligating versus conventional brackets in different bracket-archwire-angle combinations
Objective: To compare the influence of archwire material (NiTi, beta-Ti and stainless steel) and brackets design (self-ligating and conventional) on the frictional force resistance. Material and Methods: Two types of brackets (self-ligating brackets - Smartclip, 3M/Unitek - and conventional brackets - Gemini, 3M/Unitek) with three (0, 5, and 10 degrees) s

5. Comparison of static friction with self-ligating, modified slot design and conventional brackets
OBJECTIVE: To compare the static frictional forces generated at the bracket/wire interface of stainless steel brackets with different geometries and angulations, combined with orthodontic wires of different diameters. MATERIAL AND METHODS: The frictional forces were evaluated with three different types of metal brackets: a passive self-ligating (SmartCl

6. High and specialty-related musculoskeletal disorders afflict dental professionals even since early training years
OBJECTIVE: To determine how early musculoskeletal disorders (MSDs) develop in dental professionals and to explore the potential differences among distinct dental specialties. MATERIAL AND METHODS: 271 dental postgraduates majoring in five dental specialties were recruited, i.e., orthodontics, prosthodontics, endodontics, periodontics and alveolar surgery.

7. Could idiopathic osteosclerosis have correlations with palatally impacted maxillary canines?
AIM: To investigate the association between palatally impacted maxillary canines (PIC) and idiopathic osteosclerosis. METHODS: A sample of 54 subjects (28 females and 26 males, mean age of 12.98±1.59 years) with PIC was selected from the records of 1,650 orthodontic patients treated at the Discipline of Orthodontics clinics at the Dental School of the Ponti

8. Influence of different beverages on the force degradation of intermaxillary elastics: an in vitro study
Objective: The aim of this study was to evaluate in vitro the effects of frequently ingested beverages on force degradation of intermaxillary elastics. Material and Methods: One hundred and eighty 1/4-inch intermaxillary elastics (TP Orthodontics) were immersed into six different beverages: (1) Coca-Cola®; (2) Beer; (3) Orange juice; (4) Red wine; (5) Co

9. Effect of elastomeric ligatures on frictional forces between the archwire and orthodontic bracket
AIM: To evaluate the frictional force between the archwire and orthodontic bracket generated by elastomeric ligatures with polymer coating (Super slick, TP Orthodontics) and conventional ligatures (Morelli) using two types of insertion techniques. METHODS: Forty elastomeric ligatures, 20 with polymer coating and 20 conventional, were evaluated. Each type of

10. Avaliação da deflexão elástica de fios ortodônticos de níquel-titânio, calibre 0,014 / Load-deflection study of caliber 0.014 nickel-titanium orthodontic wires
OBJECTIVE: The purpose of this study was to present the magnitude and the constancy of the forces released by nickel-titanium orthodontic wires, used to treat dental crowding. Another purpose was to compare the most usual types of bending tests used to evaluate these wires: 3-point test and clinical simulation device. MATERIAL AND METHODS: Eleven groups of o

11. Quantitative analysis of S. mutans and S. sobrinus cultivated independently and adhered to polished orthodontic composite resins
In Orthodontics, fixed appliances placed in the oral cavity are colonized by microorganisms. OBJECTIVE: The purpose of this study was to quantitatively determine the independent bacterial colonization of S. mutans and S. sobrinus in orthodontic composite resins. MATERIAL AND METHODS: Seven orthodontic composite adhesives for bonding brackets were selected an

12. Orthodontics as a therapeutic option for temporomandibular disorders: a systematic review
OBJECTIVE: Orthodontics as an option for treatment and prevention of Temporomandibular Disorders (TMD) is a topic that has generated discussion over time. While an occlusion current defends Orthodontics as an alternative to treatment, another current defends more conservative and reversible treatments. The objective of this study, through a systematic litera
