Background and objective: The genetic basis of dentoalveolar characteristics has been investigated by several studies, however, the findings are equivocal. The objective of this systematic review and meta-analysis was to evaluate the heritability of dental arches and occlusal parameters in different stages of human dentition. Search methods: Ele...

Background Assessment of growth status of a patient is a key component in orthodontic diagnosis and treatment planning for growing patients with skeletal discrepancy. Skeletal maturation based on hand-wrist radiograph and cervical vertebral maturation (CVM) are commonly used methods of growth assessment. Studies have shown that stages of dental cal...

Background/Objectives: The development of dental arches is a complex adaptive system with interactions between genetic and environmental factors. At different developmental stages, the relative contribution of these factors varies. The aims of this project were to identify the longitudinal changes of dental arches in the primary, mixed and permanen...

Context Regarding the relationship between the size of the pharynx and several sagittal skeletal malocclusions and patterns of growth, contradictory findings have been documented. Aims The intent of this research was to analyze the size of the pharynx in various sagittal malocclusions and growth patterns in the Nepalese population. Settings and D...

Anterior teeth play an important role in maintaining esthetics and phonetics in human beings. Missing anterior teeth might result in rotation, shifting, and root resorption of the adjacent teeth, loss of eruption space, underdevelopment of the anterior part of the maxilla, and crossbite. Adolescent patients are very conscious about how they look, a...

Purpose This study assessed the impact of intraoral scanner type, operator, and data augmentation on the dimensional accuracy of in vitro dental cast digital scans. It also evaluated the validation accuracy of an unsupervised machine-learning model trained with these scans. Methods Twenty-two dental casts were scanned using two handheld intraoral...

Background: After an initial period of uncertainty during the COVID-19 pandemic, medical universities responded to the pandemic by innovating their methods of teaching-learning and assessment. This scoping review aimed to identify innovations in assessment in medical, dental and nursing education at the undergraduate and postgraduate levels during...

Impaction of teeth affects patients’ esthetics, speech, and masticatory efficiency. In addition, the transposition of teeth makes a case difficult to manage. This case report describes a case of a 14-year-old boy with the impaction of the maxillary right central incisor and canine along with the transposition of the right canine and lateral incisor...

Bi-maxillary protrusion is a condition with protrusive and proclined upper and lower incisors and the patient is not able to close lips without strain. The presented case reported with the chief complaint of forwardly placed teeth, with skeletal class II malocclusion, and Angle’s class I malocclusion with protrusive and forwardly placed upper and l...

The agenesis of maxillary lateral incisors affects the Quality of Life and self-esteem of patients. The management of such patients can be done by either opening the space and replacing it with the prosthesis or closing the space and substituting the canine as a lateral incisor. The choice of treatment decision depends upon the proper diagnosis and...

Maxillary canines affect the smile and facial esthetics providing upper lip and alar base support. This article presents the case report of skeletal class I malocclusion with Angle’s class III (Right) subdivision and impacted left maxillary canine of poor prognosis for traction which was managed successfully with a combined surgical and orthodontic...

Pseudo class III malocclusion is due to immature contact of incisors resulting in a forward shift of mandible. A 13-year-old male patient presented with the complaint of inability to bite properly with pseudo skeletal class III malocclusion, functional shift, and reverse overjet which was treated with fixed orthodontic treatment. The total treatmen...

Background. With the changing paradigm from primarily hard tissue to soft tissue evaluation for orthodontic diagnosis and treatment planning, the priority has shifted to bring about improvement in the profile and smile characteristics of patients. Since not only the esthetics but also the stability of orthodontic treatment is largely determined by...

Maxillary anterior teeth are often referred to as “social six”; if ectopically placed affect the quality of life of the patient. This article presents a case report of a skeletal class II patient with Angle’s class II malocclusion and ectopically erupted right maxillary central incisor which is managed with fixed orthodontics. This highlights the i...

Clinically, supernumerary teeth are able to cause different local disorders and the most common one is impaction of maxillary incisors. Impacted maxillary incisors substantially affect esthetics, function, and self‑esteem of patients. Impaction of maxillary permanent incisor is a rare clinical entity in dental practice. Although impaction of a perm...

Welcome to the 12th Annual International Conference of Orthodontic & Dentofacial Orthopedic Association of Nepal. The annual scientific conference program continues in the virtual format again. After experiencing the devastating COVID-19 pandemic last year; we had the hope that the year 2021 would bring the healthy, happy and prosperous year ahead....

Introduction: Fixed orthodontic treatment causes chronic low grade irritation on the oral mucosa. Tobacco smoking is considered to be a risk factor in the development of oral cancer. This study involves a cytomorphometric analysis on the buccal mucosal cells in patients undergoing fixed orthodontic treatment who are tobacco smokers. Methods: Exfoli...

Purpose: The present study was conducted to find the preferred mode of learning among first-year preclinical students and compare the preferred mode of learning with sex, faculty of students, and academic performance of the students using the VARK questionnaire. Methods: A cross-sectional study was done among 142 first-year Bachelor of Medicine–Bac...

Introduction Patients undergoing fixed orthodontic treatment are usually recalled electively for the adjustments of the appliances, but sometimes they appear suddenly for emergency visit which must be addressed immediately. The primary objective of this study was to assess the nature and frequency of emergency visits made by patients under labial f...

Background: Mixed dentition space analysis methods using regression equations, namely, Moyers' analysis and Tanaka-Johnston analysis are commonly used around the world. However, the applicability of these analyses among different racial groups have been questioned. The primary objective of this study was to assess the applicability of the Moyers'...
