Papilla and pontic area regeneration in patient with gingival smile: A clinical case
2018
Purpose Connective tissue grafts are widely documented as a predictable technique for treating Miller Class I and II recessions, as well as procedures in which soft tissue augmentation is required for aesthetic reasons. This article aims to explore the resolution of a clinical case with this type of problema. Clinical case This case describes a technique for reconstructing a pontic area and adjacent papilla by means of two consecutive connective tissue grafts. The first graft served to increase the amount of tissue in the horizontal direction, and the second promoted vertical reconstruction of the defect. Results and conclusion In cases with aesthetic requirements, restorative intervention …
Accuracy of check-bite registration and centric condylar position
2002
In a dentate subject a jaw relation can either be determined in maximum intercuspation and is as such given by the occlusal morphology, or the mandibular position can be allocated according to the centric position of the condyles. For comprehensive restorative treatment or analytic measures of the occlusion it is important to record the centric condylar position. Various registration methods have been described in the literature, but there is no consensus on which is the 'best'. The aim of the present study was therefore to assess the accuracy of various registration methods and evaluate a possible influence of the used materials. Four dentists were involved in the clinical part of the stud…
Color and photography in the restorative dentistry. A brief communication about color temperature, dental color and the use of light and photography …
2020
Relevance. Optical properties of dental tissues can be captured by photography, considering the characteristics of the light sources. Therefore photography might become a way to communicate the color and the characterizing aspects of the teeth, reducing the misunderstandings between the dental practice and the laboratory in the project of dental restoration. Purpose. To illustrate some ways of using the current photographic technology to document teeth color correctly, and to be able to communicate it without misunderstandings and to replicate it in a simple way. Materials and methods. The photographs were taken using Nikon D500 digital camera, Nikkor 60 mm 2.8 macro lens, Nikon SB-700 Spee…
Could sonic delivery of bulk-fill resins improve the bond strength and cure depth in extended size class I cavities?
2020
Background The implementation of restorative procedures that guarantee success and optimize clinical time is the target of investigations in Restorative Dentistry. This study aimed to analyze the influence of sonic insertion of bulk-fill (BF) and conventional (C) resin composites on the microtensile bond-strength (µ-TBS) and cure depth (CD) of large and deep class I restorations. Material and Methods Fifty-six healthy human premolars were selected and occlusal cavities (4 x 4 x 3 mm; factor C = 5) were prepared. TC - Tetric N-Ceram (BF), SF - SonicFill (BF), and Z350 - Filtek Z350 XT (C) composite resins were used to restore the cavities, using sonic (S) and non-sonic (NS) insertion techniq…
Inclusion of the periodontal ligament in studies on the biomechanical behavior of fiber post-retained restorations: An in vitro study and three-dimen…
2016
Endodontically treated teeth are known to have reduced structural strength. Periodontal ligament may influence fracture resistance. The purpose of this study was to assess the influence of including the periodontal ligament in biomechanical studies about endodontically treated and restored teeth. Forty human maxillary central incisors were treated endodontically and randomly divided into four groups: non-crowned (with and without an artificial ligament) and crowned (with and without an artificial ligament) with glass-ceramic crowns. All groups received prefabricated glass-fiber posts and a composite resin core. Specimens were tested, under a flexural–compressive load, until failure occurre…
Aerosols generation using Er,Cr:YSGG laser compared to rotary instruments in conservative dentistry: A preliminary study
2021
Background In restorative dentistry, the use of high-speed air turbine, which generates aerosols, can be associated with the transmission of airborne diseases. New laser technologies could be useful in reducing the amount of aerosols, but there is a lack of scientific research on this topic. Material and methods This is a descriptive study to analyze the amount of aerosols produced after class I cavity preparation using high-speed air turbine (group 1) and Er,Cr:YSGG laser with two different parameters (groups 2 and 3). Fluorescein dye was incorporated into the coolant reservoir in order to visualize the production of aerosols during each procedure. Tooth preparation was performed in a typo…
Advances in paediatric restorative dentistry
2009
Dental caries has been a highly prevalent and costly disease in the world, representing the most common infectious disease in the paediatric population. Caries lesions are also increasingly isolated in specific teeth and tooth morphology types, and there is growing controversy about the most appropriate restorative material for these lesions in deciduous teeth. In fact, restorative materials continuously improved in durability, strength, aesthetics, and anti-cariogenic properties. Moreover, the increasing demand for aesthetic restorative treatment has totally transformed the practice of paediatric dentistry in the last decade. Traditionally, the use of amalgam was a standard procedure in th…
Quality of YouTube TM videos on dental implants
2018
Background Patients search YouTube for health-care information. Purpose To examine what YouTube offers patients seeking information on dental implants, and to evaluate the quality of provided information. Material and Methods A systematic search of YouTube for videos containing information on dental implants was performed using the key words “Dental implant” and “Tooth replacement”. Videos were examined by two senior Oral and Maxillofacial Surgery residents who were trained and calibrated to perform the search. Initial assessment was performed to exclude non- English language videos, duplicate videos, conference lectures, and irrelevant videos. Included videos were analyzed with regard to d…
