Orthodontic emergencies and mental health of patients undergoing orthodontic treatment during COVID-19 pandemic: A questionnaire study.

Objectives: To evaluate the impact of COVID-19 pandemic on orthodontic treatment and mental health of patients undergoing orthodontic treatment and to compare their mental health with the age-matched control group.

Materials And Methods: 484 orthodontic patients (245 males and 239 females) and 200 age-matched control subjects were divided into two age groups. Group 1 had 14-18 years of adolescents (N = 274) and 100 control participants (Group 2) and Group 3 comprised of 19 years above adults (N = 210) and 100 control participants (Group 4).

Outcomes of Standard Operating Procedures Instituted for Non-COVID Outpatient Department During COVID-19 Pandemic in Rural India.

Introduction: COVID-19 has emerged as a major health care problem during 2020. The risk of infection and transmission led to imposition of a severe lockdown by the government. The diversion of health care machinery towards the control of transmission, treatment of the infected individuals led to a compromise in delivery of care towards non-COVID ailments.

Success rate, treatment duration, and pain perception in the management of palatally impacted canines using the K9 and Ballista spring: a randomized clinical trial.

Objectives: To evaluate the success rate, treatment duration, and pain perceived during forced eruption of maxillary palatally impacted canines using the K9 and Ballista springs.

Materials And Methods: Thirty unilateral palatal canine impactions of moderate and difficult category as determined by KPG index (score between 10 and 19) were enrolled. Group 1 comprised canine impactions managed with K9 springs, and Group 2 comprised Ballista springs.

Evaluation of displacements and stress changes in the maxillo-mandibular complex with fixed functional appliance skeletally anchored on mandible using miniplates: A finite element study.

Objectives: Fixed functional appliances (FFA) have been used for correction class II malocclusion but cause proclination of teeth. Recently, few studies have advocated the use of skeletal anchorage along with FFAs to prevent this side effect. The purpose of the study was to evaluate the stress distribution and displacements produced by miniplate anchored Forsus-fatigue resistant device on the maxilla, mandible, and the dentition in a Class II malocclusion patient by finite element analysis.

Nasalance Scores as a Function of Skeletal Malocclusion of English-Speaking Adults in the North Indian Population.

Objective: The objective of this study is quantitative assessment of nasalance for skeletal Class I (normative values), Class II, and III malocclusion in the English language for the North Indian population and to compare the normative values with the nasalance scores obtained from individuals with skeletal Class II and III malocclusion and to evaluate the normative values as a function of gender.

Material And Methods: The study was conducted on a total sample of 200 patients with 100, 50, and 50 in group 1 (control group, Skeletal Class I), group 2 (Skeletal Class II), and group 3 (Skeletal Class III), respectively. ANB angle (anteroposterior angle formed by point A, nasion, and point B) measured on lateral cephalogram was used to categorize the patients into 3 groups.

Assessment of orthodontic treatment outcome using Peer Assessment Rating (PAR) index among patients with non-syndromic unilateral cleft lip and palate.

Objective: To evaluate the orthodontic treatment outcome among patients with non-syndromic unilateral cleft lip and palate using the Peer Assessment Rating (PAR) index.

Materials And Methods: The retrospective study comprised a sample of 80 patients with unilateral cleft lip and palate (39 males and 41 females) with complete pretreatment and posttreatment orthodontic records. The patients were divided into two groups according to the treatment modalities.

3-Dimensional prediction of pre-surgical decompensation after atypical extractions and soft tissue simulation for ortho-surgical management of skeletal Class III malocclusion: A case report.

Three dimensional imaging systems whether in the form of digital models, facial scanning or dolphin software play an important role in proper diagnosis and treatment planning of the orthosurgical cases. This case report highlights importance of three-dimensional treatment planning in the ortho-surgical management of the patient with skeletal Class III malocclusion involving atypical extraction. On clinical examination, patient had concave profile, prominent chin, deficient midface, flat cheekbone contour and prominent nasal projection.

Comparison of reliability, validity, and accuracy of linear measurements made on pre- and posttreatment digital study models with conventional plaster study models.

Objectives: To compare the accuracy of the linear measurements made on pre- and posttreatment three-dimensional (3D) scanned digital models with conventional plaster study models.

Materials And Methods: The study was conducted on pre- and posttreatment study models of 132 patients. A 3D model scanner was used to scan the plaster models to form 3D digital models.

Speech evaluation in children with missing anterior teeth and after prosthetic rehabilitation with fixed functional space maintainer.

Introduction: Speech and language development in children is a dynamic process. Development of vocal sound into meaningful speech was one of the major discoveries which have made the human beings to reach the pinnacle of the animal kingdom. The ability to speak is determined by the flow of air into the mouth which affects pronunciation of various words and phrases.

Sleeve Push Technique: A Novel Method of Space Gaining.

Space gaining is frequently required in orthodontics. Multiple loops were initially used for space gaining and alignment. The most common used mechanics for space gaining is the use of nickel-titanium open coil springs.

PGI Bracket Positioner: A Novel Combination of Reverse Bracket Tweezer and Positioning Gauze.

The accurate bracket positioning is essential for the expression of the bracket system that affects the treatment outcome considerably and is also essential for good functional occlusion as well as facial esthetics. The proper alignment cannot be achieved without proper bracket positioning. Thus, the brackets positioning devices are an integral part of orthodontic armamentarium.
