Compared to controls, study group patients were provided with scan box and cheek retractor (Dental Monitoring®) and were instructed to take monthly intra-oral scans. Plaque Index (PI), Gingival Index (GI), and White Spot Lesions (WSL) were recorded for both groups at baseline (t₀), every …

Concomitant Bilateral Mandibular Cemento-Ossifying Fibroma And Cementoblastoma: Case Report Of An Extremely Rare Occurrence, Madiha Bilal Qureshi, Muhammad Usman Tariq, Jamshid Abdul Ghafar, Muhammad Raza, Nasir Ud Din

Department of Pathology and Laboratory Medicine

Background: Cemento-ossifying fibroma (COF) and cementoblastoma (CB) are rare benign odontogenic tumors with a predilection for the mandible. Cemento-ossifying fibroma is a fibro-osseous lesion that originates in the tooth bearing areas of jaw and shows cementum-like tissue in a fibrotic stroma. Cementoblastoma is classically related to roots of teeth with the presence of calcified cementum-like material. To date, only a single case of concomitant unilateral COF and CB has been reported in the literature.
Case presentation: We present an unusual case of a 37-year-old female who presented with two discrete bilateral swellings in the right and left mandible for 10 …

Comparison Of The Upper Airway Volume In Orthodontically Treated Cases With First Premolar Extractions, Krystal Park

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Comprehensive orthodontic treatment often entails extraction of teeth to accomplish treatment goals. A potential side effect of extraction therapy is arch length shortening resulting in decreased space for the tongue which may cause a low tongue posture and a possible reduction in airway space. The purpose of the study was to retrospectively determine if extractions of all first premolars during orthodontic treatment and the resulting movement of mandibular incisors are correlated with a reduction in airway volume.

Materials and Methods: The T1 and T2 CBCT’s of 80 patients were collected and reviewed. The cases were divided into treatment (extraction) …

Effect Of Finishing And Polishing Techniques On The Fit Accuracy And Dimensions Of Conventional And Cad-Cam Removable Partial Denture Frameworks, Majed Altoman

Loma Linda University Electronic Theses, Dissertations & Projects

Rapid advancements in computer-aided design and computer-aided manufacturing (CAD-CAM) in removable dental prosthodontics have offered new modalities for fabrication of removable partial denture frameworks. The standard tessellation language (STL) files of the scans are used to digitally design the removable partial denture (RPD) framework, which are then printed in cobalt-chromium (Co-Cr) alloy and finished and polished according to manufacturers’ recommendations. There are few studies compare the fit accuracy of the cast DPD framework versus the CAD-CAM RPD frameworks which found that CAD-RP frameworks exhibited the highest discrepancies, using different methods of evaluation. Good fit between the denture base and the …

Oral Manifestations Of Syphilis: A Review Of The Clinical And Histopathologic Characteristics Of A Reemerging Entity With Report Of 19 New Cases, Molly Housley Smith, Richard J. Vargo, Elizabeth Ann Bilodeau, K. Mark Anderson, Anna Trzcinska, Carleigh R. Canterbury, John E. Fantasia, Yeshwant B. Rawal

School of Dentistry Faculty Research and Publications

Background

Syphilis is a sexually-transmitted infectious disease caused by Treponema pallidum. Cases of primary and secondary syphilis are on the rise in the United States, with a 14.4% increase in new cases noted from 2017 to 2018 and an escalation of 71% between the years 2014 and 2018. Fulfilling its nickname of “the great imitator,” oral manifestations of syphilis may mimic a variety of infectious, neoplastic, or immune-mediated processes, both clinically and histopathologically. This large spectrum of appearances can create a diagnostic challenge to the clinician and/or pathologist, leading to delay in diagnosis or misdiagnosis.

Coronal preflaring NiTi files should possess proper hardness, resistance to fracture and flexibility. This study compared the bending resistance and cyclic fatigue resistance of three orifice preflaring NiTi files. HyFlex EDM Orifice opener (#25/12), HyFlex CM (#25/08) and One Flare (#25/09) were tested (n = 46/instrument). Bending resistance was assessed with the stress when perpendicular displacement was applied to a 3 mm point from the file tip, and was performed at either room temperature (RT, n = 10) or body temperature (BT, n = 10). Cyclic fatigue resistance was tested with an artificial ceramic root canal at RT (n = …
