Assessment Of Gingival Status And Gingival Overgrowth Among Immunosuppressed Patients In Universiti Sains Malaysia Hospital, Wan Majdiah Wan Mohamad, Syamimi Izzati Mat Zaid, Haslina Taib

Journal of Dentistry Indonesia

Drug-induced gingival overgrowth (DIGO) is defined as an abnormal growth of the gingiva due to adverse effect of some drugs such as immunosuppressant, calcium channel blocker, and anticonvulsant. Immunosuppressive drugs play an important role in controlling organ transplant rejection and were widely used to treat different diseases. Objective: Immunosuppressive drugs are used for prevention of transplant rejection and management of autoimmune disease. Drug-induced gingival overgrowth (GO) is abnormal growth of gingiva due to adverse effect of these drugs. This study aimed to assess the gingival status, the prevalence of gingival overgrowth and its associated factors among immunosuppressed patients. Methods …

Interdisciplinary Approach Of Pediatric Obstructive Sleep Apnea With Congenitally Missing Second Premolars, Shih-Hsuan Lin, Yu-Feng Chen, Yu-Chuan Tseng

Taiwanese Journal of Orthodontics

This report is a case of 11-year-old young boy who was diagnosed with pediatric obstructive sleep apnea (OSA) by sleep surgeon and was referred for further evaluation of co-therapy with intervention of orthodontic appliances. This patient is a growing case of skeletal class II jaw relation, hypodivergent facial pattern, large overjet and anterior deep overbite with congenitally missing premolars. The treatment contained two folds. In the first stage, functional appliance was designed to help with the skeletal jaw discrepancy. By doing so, the expansion over upper airway was also expected. In the second stage, fixed edgewise appliances were bonded for …

Comparison Of Shear Bond Strengths And Fiction Forces Among Various Self-Ligating Ceramic Brackets, Chia-Lin Wu, Chen-Jung Chang, Tzer-Min Lee, Jen-Bang Lo, Jia-Kuang Liu

Taiwanese Journal of Orthodontics

Purpose: Ceramic self-ligating brackets were developed recently, however, only few comparative studies had been reported about their bond strengths and friction. The aim of the study was to compare shear bond strengths and friction forces of various self-ligating ceramic brackets. Materials and methods: The present study is divided into two parts. In shear bond strength test, bovine teeth were used as a substitute for human teeth. Five groups of brackets (three ceramic self-ligating brackets including ClippyC, GeniusCrystal, DamonClear2, ClarityAdvanced (conventional ceramic bracket), Damon3MX (metal self-ligating bracket), were used and debonded with 12 brackets in each group. The shear bond strengths …

C24: Evaluation Of Visual Treatment Objective (Vto) Accuracy In Nonsurgical Orthodontic Treatment, Michael Trieu

Annual Research Symposium

Evaluation of Visual Treatment Objective (VTO) Accuracy in Nonsurgical Orthodontic Treatment

Dr. Michael Trieu, Dr. Glen Roberson, Dr. Pramod Sinha, Dr. Calvin Heinrich, Dr. Kishore Chaudhry

Abstract

Background and Objectives

Visual treatment objectives (VTOs) predict the effects that different hard tissue movements can have on a person’s facial soft tissue. This is a powerful tool that can provide doctors with a visual prediction of what a patient would look like through various surgical and orthodontic movements while also providing a means to effectively communicate with patients. Initially, VTOs were drawn by hand, but technological innovations have provided the ability to …

Utilization Of A New Web-Based Application For Case Difficulty Assessment As A Predictor For Procedural Errors In Nonsurgical Root Canal Treatment, Watraat Unmona Hasanat

Orthodontics and Endodontics Theses

Introduction: There are currently no established guidelines to determine which cases general practitioners should refer to an endodontist for root canal treatment. The American Association of Endodontists (AAE) has developed the EndoCase mobile application (ECA), which utilizes either a full or abridged rubric to assign case difficulty level and provide referral guidelines to general practitioners and dental students. Objective: The objective of this study was to determine whether the abridged criteria of the EndoCase application can help predict the incidence of procedural errors in nonsurgical root canal treatment of mandibular molars in an undergraduate dental clinic based on the difficulty …

Removable Appliance Therapy For Interceptive Orthodontic Treatment, Vikas Gupta, James Chen

Orthodontics and Endodontics Theses

Introduction: Socioeconomically disadvantaged children have limited access to orthodontic services not only because of their families’ competing needs for limited resources, but also because of the limited availability of orthodontists in their communities and a shortage of orthodontists who are willing to treat patients enrolled in Medicaid. We will systematically explore the hypothesis that an early interceptive treatment protocol using removable appliances provides the same treatment outcome but better cost-effectiveness than a traditional fixed-appliance protocol. Methods: Interim data on a prospective study with patients being treated either in private practice with rational fixed Phase I orthodontic treatment (n=11) or in …

Comparison Of Maxillary Expansion Between Clear Aligners And Removable Expansion Appliance In The Mixed Dentition, Micaela Zaverdinos, Paul Kasrovi, James Chen, Heesoo Oh

Orthodontics and Endodontics Theses

Introduction: Orthodontic and orthopedic expansion is necessary to create space to resolve crowding due to arch deficiency or tooth size discrepancy. The Invisalign First clear aligner appliance as a modality for early interceptive orthodontic treatment has become incorporated into orthodontic practices in very recent years. The present study aims to investigate the magnitude of expansion of the Invisalign First clear aligner appliance compared to a Schwartz removable expander in patients with mixed dentition. Additionally, the study aims to compare the efficacy and predictability of Invisalign First clear aligners in this population. Materials & Methods: In this retrospective study, a sample …

Orthodontics and Endodontics Theses

ABSTRACT Introduction: Medical imaging continues to play an increasing role in health care and is an integral part of medicine and dentistry. Recent technological advancements have led to the development of fully automated landmark identification (ALI) systems capable of tracing Cone-Beam Computed Tomography (CBCT). The purpose of this study was to evaluate the accuracy and reliability of an ALI system as a tool for automatic landmark location compared to human judges. Methods: One hundred subjects’ CBCT volumes from multiple imaging centers were traced by two human judges who were calibrated and had an ICC close to 1. Fifty-three landmarks were …

1 Long Term Impact Of Microimplant Assisted Rapid Palatal Expansion On Soft Tissue Nasal Morphology, Laura Chew, Heeyeon Suh, Joorok Park, Heesoo Oh

Orthodontics and Endodontics Theses

Introduction: When skeletal transverse discrepancies exist between the maxilla and mandible, they commonly manifest in dental malocclusion. If left uncorrected, the malocclusion can lead to periodontal issues, tooth fractures, tooth loss, or other significant dental problems. Utilization of microimplants in palatal expansion aims to correct transverse discrepancies between the maxilla and mandible by separating the palatal suture in a parallel manner aimed at maximizing skeletal changes and minimizing dental side effects. Overlying soft tissue changes can be affected by the induced skeletal changes. The purpose of this study is to evaluate skeletal expansion and the overlying soft tissue change that …
