Purpose: The objective of this study was to determine how apical, coronal and occlusal arch forms change following orthodontic treatment with fixed appliances and to establish a base for future studies. Material and Methods: Maxillary and mandibular apical, coronal and occlusal landmarks of 27 subjects were selected on their respective CBCT images at two time points: pre-orthodontic treatment (T1) and post-orthodontic treatment (T2). Comparisons were made between the two time points to evaluate how each arch form changed …

Effectiveness Of Resin Infiltration And Mi Paste Cpp-Acp In Masking White Spot Lesions, Melissa Wu Bailey

Loma Linda University Electronic Theses, Dissertations & Projects

The development of decalcification around orthodontic brackets and bands, commonly called white spot lesions (WSLs), is often observed in patients with poor oral hygiene during treatment (Behnan et al., 2010, Rodgers et al., 2010). In many instances, these WSLs continue to be visible after the removal of fixed appliances and after natural remineralization. The purpose of this in vitro study was to compare the effectiveness of two treatment modalities, resin infiltration (RI) and Casein Phosphopeptide Amorphous Calcium Phosphate (CPP-ACP), at improving the light reflectivity and thus the appearance of WSLs using spectrophotometric analysis. Sixty extracted human third molars were partially …

Analysis Of Periapical Biopsies Submitted For Histopathological Evaluation: A Retrospective Study, Abdullah I. Alqaied

Master's Theses

Apical periodontitis is the most common pathological process in the periapical region. Disciplined clinical and radiographic evaluations and appropriate diagnostic tests can detect lesions related to apical periodontitis. Aside from this, lesions mimicking pulp-related pathology but unrelated to pulpal infection and necrosis are occasionally discovered in the periapical region. The objective of this study was two-fold: (1) to determine the prevalence of diverse periapically located pathological entities, and (2) to apply that information to evaluate the rationale for routine submission of surgically obtained tissue for histological examination and diagnosis. Methods: A 5-year retrospective analysis of pathology reports from the UCONN …

Remarkable Resilience Of Teeth (How Are Teeth So Brittle Yet So Resilient), Paul J. Constantino

Biological Sciences Faculty Research

Tooth enamel is inherently weak, with fracture toughness comparable with glass, yet it is remarkably resilient, surviving millions of functional contacts over a lifetime. We propose a microstructural mechanism of damage resistance, based on observations from ex situ loading of human and sea otter molars (teeth with strikingly similar structural features). Section views of the enamel implicate tufts, hypomineralized crack-like defects at the enamel–dentin junction, as primary fracture sources. We report a stabilization in the evolution of these defects, by ‘‘stress shielding’’ from neighbors, by inhibition of ensuing crack extension from prism interweaving (decussation), and by self-healing. These factors, coupled …

Accuracy Of Unsegmented Cbct In Mesial-Distal Tooth Measurements, Todd Wesslen

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Cone-beam computed tomography (CBCT) scans may be used to measure mesial-distal (MD) tooth width for orthodontic diagnosis and treatment planning. Purpose: The objective of this study was to determine if MD tooth measurements from unsegemented CBCT scans in the axial, sagittal, and coronal planes or from a panoramic reconstruction correlate and agree with respective measurements made on study models. Material and Methods: Using stone models of 30 subjects, reference MD tooth measurements were made using digital calipers. From CBCT scans, five different methods of measuring MD width were used and compared to the reference: (1) points chosen from orthogonal …

Profile Attractiveness In Borderline Class Iii Surgical/Orthodontic Cases, Melina Adamian

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: This study evaluated differences between laypersons and orthodontists in rating facial attractiveness in borderline class III surgical/orthodontic cases. The purpose was to determine whether orthognathic surgery or camouflage is a better alternative for observable esthetic improvement in borderline Class III surgical/orthodontic patients. This study will aid the orthodontist in recommending treatment options to enhance profile attractiveness of borderline Class III surgical/orthodontic patients. Materials and Methods: Thirty profile images of treated borderline class III surgical/orthodontic cases were selected. Fifteen of the profile images were of cases that had been treated by orthodontics alone, and fifteen images were of cases that …

Sleeping Tongue Posture And Its Relationship To Craniofacial Morphology, Brent J. Tingey

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: There exists good consensus in the literature supporting the notion that resting tongue posture is an important factor in dental arch development and maintenance as well as airway control. What has yet to be quantitatively measured is the duration of time that a subconscious, resting tongue posture is maintained and whether such posture differs among various craniofacial morphologies. Quantifiable measurements might allow for prediction of tongue-posture-related problems specific to certain facial types. Purpose: The objective of this study was to record sleeping tongue posture over time in 27 subjects and to compare findings with craniofacial morphology determined by cephalometric …
