Journal of Dentistry Indonesia

The diagnosis and prognosis of teeth with endo-perio lesions present a major challenge for dentists. Proper diagnosis is critical in determining treatment and the long-term prognosis. However, treating complex endodontic and periodontal lesions is one of the most common challenges in current clinical practice. The coexistence of pulpal and periodontal tissue damage may complicate diagnosis and further influence dental prognosis. This article consists of a case report evaluating the efficacy of xenografts and resorbable membrane pericardium in treating bifurcation lesions associated with periodontal lesions of the left mandibular first molar. A 22-year-old female patient was referred by conservative dentistry with …

Machine Learning For Automated Cervical Vertebral Maturation Assessment On Lateral Cephalograms, Nuo Dong

Theses & Dissertations

Introduction: Skeletal maturation age is an important guide in growing adolescent patients to determine the proper time to start orthodontic treatment. The most practical and commonly used method to determine skeletal age in today’s clinical practice is the Cervical Vertebral Maturation (CVM) method [2]. Based on the morphology of the cervical vertebrae, six maturational stages can be determined – designated CS 1 to CS 6. The main drawback of this technique is the time required to determine CS number. Objective: In this research a machine learning (ML) algorithm to automatically determine CVM staging from the lateral cephalometric radiograph was developed. …

Three-Dimensional Analysis Of Condylar Displacement After Orthognathic Surgery In Patients With Facial Asymmetry, Teresa Bae

Theses & Dissertations

Facial asymmetry is apparent when there is a clinically significant variation between the two halves of the face. There can be varying degrees of facial asymmetry and mild asymmetry can be treated by orthodontics alone. For severe facial asymmetry a combination of orthodontics and orthognathic surgery may be necessary. The condyle must be in a stable position following surgery to have functional and structural stability and prevent relapse. This research proposal is to perform a retrospective CBCT study on the displacement of the condyle following orthognathic surgery in patients with facial asymmetry. The CBCTs were obtained from Taipei Veterans General …

Dentistry And The Law: Requiring Proof Of Adoption/Retaining Orthodontic Models, Dan Schulte Jd

The Journal of the Michigan Dental Association

In this Dentistry and the Law column, a dentist seeks guidance on handling a situation where racial differences between a child and an accompanying adult raised concerns during an examination, leading the dentist to request proof of adoption. The response clarifies that asking for proof of adoption is not illegal, citing relevant Michigan adoption statutes. The column advises adopting an office policy, emphasizing human trafficking training. Additionally, a dentist inquires about retaining orthodontic models and X-ray films. The answer recommends assuming orthodontic models are part of dental records, subject to a 10-year retention period. Patients can be given their models, …

Taiwanese Journal of Orthodontics

Purpose: It is valuable to detect whether bone thickness measurements performed on lateral cephalograms reflect the values obtained from three-dimensional images. The present study compared lateral cephalometry and cone-beam computed tomography (CBCT) for evaluating alveolar bone thickness surrounding maxillary central incisors.

Methods: The study included the records of 55 patients who had both lateral cephalograms and CBCT scans of the maxilla. In cephalograms, the alveolar bone thickness was measured at the crestal, middle, and apical levels of maxillary incisors at the buccal and lingual sides. Bone thickness was also measured at the corresponding points on CBCT images, and the data …

Facial Growth: Does It Play A Role In Long-Term Stability Of Orthodontic Treatment?, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

Following orthodontic treatment there is usually a period of retention to maintain the treatment result. This period can vary from a few years to even lifelong retention all depending upon the clinician, type of treatment and severity of the initial malocclusion. In most cases retention is planned for one to two years, but some clinicians routinely recommend continuous retention into adulthood. The retention planned for a patient is unfortunately often based on intuition rather than on scientific evidence. Furthermore, the retention is frequently not planned based on the initial malocclusion, the patient's facial growth pattern nor is attention paid to …

Comparison Of Thickness Between Thermoformed And Printed Orthodontic Aligners, Omar Souman

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: The fabrication of thermoformed orthodontic aligners involves processes that irreversibly alter material properties, resulting in aligners that exhibit high variation in thickness. The non-uniform thickness can lead to unpredictable forces that can adversely affect orthodontic tooth movement. With recent technological advancements enabling the printing of orthodontic aligners, it is of clinical interest to investigate their variation of thickness.

Purpose: This study utilized Micro-Computed Tomography (Micro-CT) and Geomagic Control X metrology software to compare the thickness of thermoformed and direct printed aligners.

Materials and Methods: Intraoral scans of 13 orthodontic patients were used to generate standard tessellation …

Oral Leukoplakia: Diagnosis And Management Revisited, Isaäc Van Der Waal

Journal of Dentistry Indonesia

The definition of oral leukoplakia has not much changed during the past five decades and is still a definition by exclusion of ‘known’ lesions. Therefore, a diagnosis of leukoplakia is not always a straightforward one for the clinicians and, to some extent, also for the pathologists. The traditional clinical classification in homogeneous and nonhomogeneous leukoplakia may just be simplified into leukoplakia (thin and thick/verrucous) and erythroleukoplakia. In spite of numerous reported predictive molecular and genetic parameters of malignant transformation, the presence and grade of epithelial dysplasia as assessed by histopathological examination is still the most important one. Of the various …

How To Manage Fan’S C Shape Canals Along With S Shape Morphology In Indian Population: A Case Series And Narrative Review, A Lavanya, Rajendra Kumar Tewari

Taiwanese Journal of Orthodontics

A 20-year-old male adult came to the clinic with a chief complaint of poor dental alignment. Clinical examination had revealed Skeletal Class III with an upper right buccally positioned high canine, anterior crowding, midline deviation and both maxillary lateral incisors crossbite. Four bimaxillary premolars were extracted. Improved super-elastic Ti-Ni alloy wire (ISW, developed by Tokyo Medical and Dental University) leveling was performed to relieve the crowding and to correct the high canine and midline deviation. Intermaxillary elastics (IME) was applied for a better interdigitation. Treatment was completed within 29 months and a desirable occlusion was achieved.
