Association of Vital Pulp Therapy Outcomes with Tooth Type, Arch Location, Treatment Type, and Number of Surfaces Destroyed in Deciduous Teeth: A Ret…
2021
There is a paucity of information concerning vital pulp treatment outcomes in the undergraduate teaching setting. This study aimed to determine which type of deciduous molar, arch location, type of vital pulp therapy, and the number of carious surfaces involved had a better prognosis when carried out by undergraduate dental students. The method used was the review of clinical records of 590 patients with 600 deciduous molars, that visited the outpatient undergraduate dental clinics for vital pulp therapy. Statistical analysis used to determine the associations of tooth type, arch location, treatment type, and the number of carious surfaces involved in successful outcomes was logistic regres…
Pericoronitis: A clinical and epidemiological study in greek military recruits
2019
Background This paper presents a statistical analysis of epidemiological, clinical and radiographical characteristics of third molar-related pericoronitis. Material and methods 650 conscripts of the First Training Division of Conscript Soldiers of 2005 in Greece were recruited for the study. Each conscript was given a questionnaire and underwent a clinical test and a radiographic examination. The tested variables included the conscripts' personal information, oral hygiene parameters along with the radiographic angulation of the third molar, the level of impaction and their classification in relation to the edge of the mandible. Results The prevalence of pericoronitis was found to be 4.92%. …
Prospective study of monolithic zirconia crowns: clinical behavior and survival rate at a 5-year follow-up
2020
Purpose To evaluate the clinical behavior and survival of full coverage monolithic zirconia crowns on posterior teeth over a 5-year follow-up. Methods Fifty patients were recruited and underwent restoration with a Lava Plus monolithic zirconia crown (Lava™ Frame Zirconia, 3M Espe, Germany) on premolars or molars. Patients were monitored over a 5-year follow-up (2014-19), recording any biological and/or mechanical complications; these data were used to estimate the crowns' success rate. Periodontal clinical parameters were recorded (pocket probing depth (PPD), plaque index (PLI), bleeding on probing (BOP), and gingival recession (GR)). Wear to the zirconia crowns and antagonist teeth were al…
ONJ in osteometabolic patients: NO guilty verdict for teeth extraction
2018
The aim of this study is to evaluate retrospectively the impact of some variables on the risk of oNJ onset in osteometabolic non-cancer patients by logistic regression analyses.
Relationship between pulp-tooth volume ratios and chronological age in different anterior teeth on CBCT
2017
Background The CBCT imaging technique exhibits proper accuracy to determine the internal anatomy of teeth. Therefore, this technique can use to estimate age by measuring the amount of decrease in the volume of the pulpal cavity of teeth. The aim of the present study was to evaluate the correlation between chronological age and pulp-to-tooth volume ratios in anterior teeth with the use of the CBCT technique and to determine a regression model to estimate human age. Material and methods In this present descriptive-analytical study, 122 subjects (46 males and 76 females), with an age range of 13-70 years, were evaluated. The MIMICS software program was used to determine the pulp-to-tooth volum…
Dentin-pulp complex reactions in conventional and radiation-related caries: A comparative study
2019
Background Radiation-related caries (RRC) is one of the most significant oral toxicities of head and neck radiotherapy (HNRT); however, the potential of radiation to directly cause harmful dentin and pulpal effects and impair response to caries progression is controversial. Material and Methods Therefore, the aim of this study was to characterize the reactions of the dentin-pulp complex in teeth affected by RRC. Patients and methods: Twenty-two carious teeth extracted from 22 head and neck cancer (HNC) patients were divided into control (conventional caries; n=11) and irradiated (RRC; n=11) groups and paired matched by dental homology, clinical patterns of caries progression following the P…
Human exfoliated deciduous teeth and oral mucosa: promising applications in tissue regeneration
2018
In the last three decades, the constantly increasing need for therapies, efficiently preventing and/or treating human diseases, has raised the interest in Regenerative Medicine (RM). RM is based on employing mesenchymal stem cells (MSCs), that showed to have great proliferation, self-renewal and multilineage differentiation potential, in vitro as well as in vivo. The opportunity of an accessible, painless and low-cost reservoir of MSCs constitutes the first important step of a successful regenerative therapy to include in the current clinical practice. Oral cavity has recently demonstrated to contain different MSCs niches: dental pulp from permanent and deciduous teeth, periodontal ligament…
Development of a New Type of Incisal Table for Prosthetic Articulators
2010
This study illustrates the effectiveness of an advanced incisal table surface, featuring adjustable curvature, in the sake of more accurate articulator kinematics in anterior teeth reconstruction. Prosthetic articulators, used by dental technicians in reconstructive dentistry, are adjustable instruments that simulate the motion of mastication between dental casts: usually, the forward motion (protrusion) of the mandible is guided by sliding a pin over a flat table in order to recreate those movements when incisal teeth are missing. However, such protrusion is an approximation of the exact motion, since flat incisal tables have a limited set of adjustments. Customized software has been devel…
Mandibular talon cusps: A Systematic review and data analysis.
2014
Objectives: The purpose of the present study was to evaluate mandibular talon cusps distribution from the compre - hensive literature search and proposal of new classification Material and Methods: The study was a review of articles published in the English language from January 1960 to December 2013. The PubMed/MEDLINE/Google Scholor databases were searched electronically using "talon cusp", "dens evaginatus", "anterior teeth", mandible, "primary dentition" and "permanent dentition" as search terms in various combinations. The citation lists from the included references were subsequently examined, and a hand search was also performed in an attempt to identify additional reports. The distri…
Digital protocol for creating a virtual gingiva adjacent to teeth with subgingival dental preparations.
2019
Abstract Purpose This article describes a digital technique used to record gingival emergence profiles modeled for the prosthetic restoration of teeth prepared using biologically oriented preparation technique (BOPT). Materials and methods The description of the technique of intraoral recording, manipulation of digital files, and chairside protocol of prosthetic restorations is developed in the present manuscript on two anterior teeth treated with vertical and subgingival dental preparations for restoration with ceramic crowns. The manipulation of the digital files registered with an intraoral scanner with software that allows its alignment (best-fit) and the performance boolean of operatio…
