Can a Self-etching Primer be Effective in Bonding Aligner Attachments to Different Types of Ceramics?

Objective: This study aimed to evaluate the effectiveness of pretreatment with a self-etching primer for bonding aligner attachments to lithium disilicate (LD) and monolithic zirconia (MZ) ceramics.

Methods: Forty ceramics, including LD (n=20) and MZ (n=20), were divided into four study groups according to the surface pretreatments: LD specimens pretreated with universal primer (Monobond Plus, MP) after hydrofluoric acid etching (Group 1); MZ ceramics pretreated with MP after sandblasting (Group 2); LD ceramics pretreated with self-etching ceramic primer (Monobond etch & prime, MEP) (Group 3); and MZ ceramics pretreated with MEP after sandblasting (Group 4). The aligner composite (GC Aligner Connect) and universal adhesive (GPremio Bond) were used to prepare the resin attachments.

Objective: The aim of this study was to evaluate the self-concept and psychosocial status measured by the levels of social phobia and loneliness in a sample of adolescent patients with different malocclusions and to explain the relationships, if any, between malocclusions.

Methods: This study was performed on 90 (41 females and 49 males) orthodontic patients with a mean age of 13.52±1.

Effects of Different Combinations of Er:YAG Laser-Adhesives on Enamel Demineralization and Bracket Bond Strength.

Objective: The purpose of this study was to investigate the demineralization around brackets and shear bond strength (SBS) of brackets bonded to Er:YAG laser-irradiated enamel at different power settings with various adhesive systems combinations.

Methods: A total of 108 premolar teeth were used in this study. Teeth were assigned into three groups according to the etching procedure, then each group divided into three subgroups based on the application of different adhesive systems.

A reliable method for evaluating upper molar distalization: Superimposition of three-dimensional digital models.

Objective: The aim of this study was to evaluate the reliability of measurements obtained after the superimposition of three-dimensional (3D) digital models by comparing them with those obtained from lateral cephalometric radiographs and photocopies of plaster models for the evaluation of upper molar distalization.

Methods: Data were collected from plaster models and lateral cephalometric radiographs of 20 Class II patients whose maxillary first molars were distalized with an intraoral distalizer. The posterior movements of the maxillary first molars were evaluated using lateral cephalometric radiographs (group CP), photocopies of plaster models (group PH), and digitized 3D models (group TD).

Comparison of Bolton analysis and tooth size measurements obtained using conventional and three-dimensional orthodontic models.

Objectives: The aim of this study was to compare the accuracy, reproducibility, efficacy and effectiveness of measurements obtained using digital models with those obtained using plaster models.

Materials And Methods: A total of 20 digital models were produced by the Ortho Three-dimensional Models (O3DM) Laboratory and their software (O3DM version 2) was used to obtain measurements. Identical plaster models were used to obtain measurements of teeth with a vernier caliper.

Lasers in orthodontics.

Many types of dental lasers are currently available that can be efficiently used for soft and hard tissue applications in the field of orthodontics. For achieving the desired effects in the target tissue, knowledge of laser characteristics such as power, wavelength and timing, is necessary. Laser therapy is advantageous because it often avoids bleeding, can be pain free, is non-invasive and is relatively quick.

Effect of bracket type on halitosis, periodontal status, and microbial colonization.

Objective: To determine the effect of bracket type on halitosis, periodontal status, and microbial colonization.

Materials And Methods: Forty-six patients scheduled for fixed orthodontic treatment (age 11-16 years) were selected from the orthodontic department of Suleyman Demirel University. Patients were divided into two groups with random distribution of brackets; 23 patients were treated with self-ligating brackets (group SLBs), the others with conventional brackets (group CBs).

The relationship of orthodontic treatment need with periodontal status, dental caries, and sociodemographic factors.

The aim of this study was to determine the relationship of orthodontic malocclusion with periodontal status, dental caries, and sociodemographic status. Our study population consisted of a sample of 836 school children (384 male and 452 female, aged 11-14 years). Four experienced orthodontists and two experienced periodontists performed the clinical examinations.

Comparison of retention characteristics of Essix and Hawley retainers.

Objective: We aimed to compare the retention characteristics of Essix and Hawley retainers.

Methods: Adolescents undergoing fixed appliance treatment at 2 centers were recruited for this study. Twenty-two patients (16 women and 6 men) wore Essix retainers (Essix group) while 20 (14 women and 6 men) wore Hawley retainers (Hawley group).

Oxidative imbalance and anxiety in patients with sleep bruxism.

Objective: We evaluated the relationship among sleep bruxism (SB), antioxidant/oxidant status, and anxiety level to determine whether antioxidant/oxidant status may be used as a biological marker of SB.

Study Design: Thirty-three SB and 32 healthy patients of similar age, sex, and body mass index were enrolled, venous blood was collected, and anxiety scores were determined. Plasma samples were analyzed for total oxidant status, antioxidant status, and oxidative stress index.

Effects of Ginkgo biloba on experimental rapid maxillary expansion model: a histomorphometric study.

Objective: We aimed to investigate the effect of systemic Ginkgo biloba in rapid maxillary expansion (RME).

Study Design: We randomly divided 24 rats into 3 groups: expansion only (EO), expansion plus Ginkgo biloba (GB), and no expansion (NE). Expansion appliances were affixed to the maxillary incisors.

Systemic propolis stimulates new bone formation at the expanded suture: a histomorphometric study.

Objective: To investigate the effects of systemically given propolis on the expanded premaxillary suture in a rat study model.

Materials And Methods: The 24 rats were randomly divided into three groups-only expansion (OE), expansion plus propolis (PRO), and nonexpansion (control) groups. After the 5-day expansion period was completed, the OE and PRO groups underwent 12 days of mechanical retention.

Effect of fixed appliances on oral malodor.

Introduction: The objective of this study was to evaluate the effect of fixed appliances on oral malodor.

Methods: Forty-one patients participated in this study. They were randomized into 2 groups: treated with fixed orthodontic appliances and untreated controls.

Objectives: The aim of this study was to compare the shear bond strength (SBS) of two different light sources under different thermal cycle frequencies.

Methods: Ninety human premolar teeth were divided into six groups, in which three groups consisted of halogen groups - Group I was cured with halogen without thermocycle, Group II cured with halogen with 500 thermocycles, and Group III cured with halogen with 10,000 thermocycles. The other three groups consisted of Plasma arc (PAC) group - Group IV was cured with PAC without thermocycle, Group V cured with PAC thermocycled 500 cycles, and Group VI cured with PAC thermocycled 10,000 cycles.
