Lately, the spread of COVID-19 has become a significant worry in dental offi...

Introduction: Bimaxillary protrusion is an occlusal feature characterized by protrusive and proclined upper and lower incisors, associated with increased flattening of the lips and greater than average degree of lip prominence. It is considered one of the malocclusion types that stimulate patients to seek orthodontic treatment to improve facial sym...

Objective: Data available on prevalence of malocclusions are mostly local or national-based, therefore this study aimed to pool data to determine the distribution of malocclusion traits in the permanent dentition across the African continent. Methods: Recent studies published between 1990 and 2021 in PubMed, AJOL, PMC and Scopus on malocclusion pre...

Background The psychological impact of malocclusion, social acceptance, self-esteem, and the development of personality traits are considerations that can affect the demand for orthodontic treatment. The aim of this study was to assess the effect of malocclusion severity and self-perceived smile and dental aesthetics on self-esteem among adolescent...

Background The maxillary midline diastema is a space between both upper central incisors which is more than 0.5 mm in width, and there are varying factors attributed to its occurrence. Aim The purpose of this study was to determine the relationship between maxillary midline diastema width and labial frenum attachment among secondary school student...

Background: Tooth variation within populations is important for anthropologists and dentists. The objective was to compare crown dimensions among three Nigerian ethnic populations. Materials and methods: An electronic caliper was used to measure mesiodistal and buccolingual tooth width of maxillary and mandibular permanent teeth except third mol...

The impact of malocclusion on the psyche of an individual could range from mild reservations about teeth appearance to debilitating anxiety about self-image and self-esteem. The purpose of this study was to evaluate the psychosocial impact of malocclusion, determine its association with severity of malocclusion, and assess the effect of gender, age...

Objectives: Due to the COVID-19 pandemic, undergraduate dental education institutions substituted face-to-face learning with online learning. Although online learning has provided many advantages for higher education institutions, there remain many challenges which hinder its usage effectively. This research examined association between the level o...

Background: Orthodontic practitioners have a high exposure risk to cross infection with COVID-19 due to proximity with the patients and frequent exposure to body fluids during procedures. Objectives: This study aimed to investigate COVID-19 related experiences, knowledge, attitudes, and behaviours among orthodontists and orthodontic residents in Ni...

Objectives Two of lives’ most important domains may be in conflict with each other. This study investigated the association between perceived work-life balance (WLB), work interference with family (WIF), family interference with work (FIW), and organizational commitment (OC) of Nigerian orthodontists and orthodontic residents. Materials and Methods...

Background: The job of the orthodontist involves long working hours and interaction with each patient for many years before the conclusion of treatment thus orthodontists may experience peculiar levels of stress. Occupational stress has been proven to have negative consequences and can result in not only burnout but also hypertension and even suici...

Introduction: Orthodontic treatment planning within a public health system needs information on the need for orthodontic treatment within the population. It is imperative to have epidemiological data from which the need for orthodontic care in any region can be estimated. The present study, therefore, aimed to determine the orthodontic treatment n...

This narrative review provides a comprehensive summary of the implications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (COVID-19) on orthodontic treatment and a review of treatment protocols recommended for control of spread of this infection, using currently available data and literature....

INTRODUCTION: Motivation for orthodontic treatment among adolescents has been linked with patients' response during treatment. Parents have also been seen to be influencing factors in patient motivation. This study investigates the motivation for orthodontic treatment among patients and their parents/guardians. MATERIALS AND METHODS: Data were obta...

Objective: This study aimed to investigate the prevalence of subdivision Class II/1 and II/2 malocclusion, and analyse the anteroposterior skeletal characteristics associated with Class II/1 and II/2 malocclusion. Methods: Records of patients diagnosed with class II malocclusion between June 2012 and January 2017 were obtained from the LASUTH ortho...

Objectives: To compare the anterior facial height parameters among the sexes and to find facial height variations among Class I, II and III skeletal pattern groups. Methods: The sample comprised of 60 (26 females and 34 males) lateral cephalometric radiographs traced and grouped into Class I, II and III skeletal relationships based on their ANB val...

Background: Congenitally missing or aberrant morphology of maxillary lateral incisors may cause aesthetic and functional impairment of the affected individual. There is however paucity of information on its prevalence and pattern of presentation among Nigerians. Aim: To determine the prevalence of agenesis, peg and small maxillary lateral inciso...

ABSTRACT Sickle cell disease (SCD) is a hereditary autosomal recessive disorder of haemoglobin resulting in chronic anaemia and vaso-occlusion and mainly affects the black population. There have been documented case studies suggestive of craniofacial changes in children with sickle cell disease. Previous studies that documented the orthodontic prof...

The effects of digit sucking on dentofacial structures has been widely studied, but its relationship with the function and/or shape of the palate has been negleted. A clinical observation of high palatal vault has been reportedly associated with digit sucking. However, the description has been made on the basis of subjective clinical observation ra...

Objective: The aims of this study were to investigate factors influencing career choice as well as to identify future plans of Nigerian orthodontic residents.
