Methods: An anonymous 40-question questionnaire was sent online to the patients of private orthodontic clinics in 2 cities of Birjand, and Mashhad, capitals of Eastern provinces of Iran. Orthodontic patients of Mashhad dental school received the questionnaire as well.

Evaluation of Divine Proportions in Face and Smile of Patients With Unilateral Cleft Lip and Palate.

Introduction And Aim: The facial view of patients with cleft lip and palate greatly affects their psychological well-being and usually leads to introspection. The aim of this study was to compare the face and smile of cleft lip and palate patients and normal population with divine proportion.

Method: In this retrospective study, 20 female patients (14-25 years) with unilateral cleft lip and palate, who referred to Orthodontic Department of Mashhad School of Dentistry, were selected.

Evaluating the Efficacy of a Modified Piezo-Puncture Method on the Rate of Tooth Movement in Orthodontic Patients: A Clinical Study.

Objective: Owing to the increasing demand from orthodontic patients for a more rapid treatment, many studies have focused on accelerated tooth movement. Currently, one of the prevalent methods to achieve accelerated tooth movement is piezo-puncture. The aim of the present study was to evaluate the effect of a modified piezo-puncture method on tooth movement rate and type during canine retraction.

Antimicrobial and physical properties of alginate impression material incorporated with silver nanoparticles.

Background: Self-disinfecting impression materials would reduce time and energy needed for impression disinfecting process in clinic. The aim of this study was to evaluate the antimicrobial effect of alginate mixed with nanosilver solution at a concentration of 500 ppm and 1000 ppm on common oral microorganisms and assess changes in working time, setting time, and surface detail reproduction.

Materials And Methods: In this study, three groups were assigned.

Efficacy of Platelet-Rich Fibrin Combined with Autogenous Bone Graft in the Quality and Quantity of Maxillary Alveolar Cleft Reconstruction.

Introduction: The aim of this study was to evaluate the effect of platelet-rich fibrin (PRF) on the quality and quantity of bone formation in unilateral maxillary alveolar cleft reconstruction using cone beam computed tomography.

Materials And Methods: This study was conducted on 10 non-syndromic patients with unilateral cleft lip and palate within the age group of 9-12 years. The study population was randomly assigned into two groups of PRF and control, each of which entailed 5 cases.

Piezopuncture-Assisted Canine Distalization in Orthodontic Patients: Two Case Reports.

With the increasing number of young adults seeking orthodontic treatment to improve their smile esthetics or oral function, the time spent wearing brackets is one of the biggest challenges for these patients. Various surgical techniques have been developed over the years to accelerate tooth movement and reduce the total treatment time. A newly introduced, minimally invasive procedure namely piezopuncture, which uses a piezosurgical tool to create multiple cortical punctures through the gingiva, is presented in this report of two extraction cases.

Facial Anthropometric Evaluation of Unilateral Cleft Lip and Palate Patients: Infancy Through Adolescence.

Introduction: Craniofacial anthropometric studies measure the differences in humans' craniofacial dimensions. The aim of this study was to determine facial anthropometric dimensions of newborn to 12-year-old girls with nonsyndromic unilateral cleft lip and palate (UCLP).

Methods: In this cross-sectional analytical study, data was collected from 65 infant to 12-year old girls with UCLP.

Retentive Strength of Orthodontic Bands Cemented with Amorphous Calcium Phosphate-Modified Glass Ionomer Cement: An In-Vitro Study.

Objectives: The aim of this study was to evaluate and compare the retentive strength of orthodontic bands cemented with amorphous calcium phosphate (ACP)-containing and conventional glass ionomer cements (GICs).

Materials And Methods: One-hundred-and-twenty mandibular third molars were embedded in acrylic resin blocks with the buccal surface of crowns perpendicular to the base of the mold. The teeth were randomly divided into four groups containing 30 teeth each.

Comparison of esthetics perception and satisfaction of facial profile among male adolescents and adults with different profiles.

Objective: To evaluate esthetics perception and satisfaction of the facial profile among Iranian male adolescents and adults.

Materials And Methods: In this cross-sectional study, male subjects referred to Orthodontic Department of Mashhad Dental School were enrolled (n = 84) and were divided into two groups: Adolescents (n = 39), and adults (n = 45). They were also assigned to straight, convex, or concave profile groups based on the facial profile angle (G-Sn-Pog').

Comparison of three different sterilization and disinfection methods on orthodontic markers.

Background: Marking pencils which are frequently used in orthodontics may cause microbial contamination. The purpose of this study was to evaluate and compare the effectiveness of three disinfection and sterilization methods (autoclave, glutaraldehyde solution, and Deconex spray) on orthodontic markers.

Materials And Methods: One hundred and twenty orthodontic markers were divided into four groups each 30 pencils: One control group and three groups for three different disinfection/sterilization methods.

Evaluation of the effects of three different mouthwashes on the force decay of orthodontic chains.
