"In vivo" evaluation of the vascular pattern in oral peri-implant tissues.
2011
Abstract Introduction The vascularisation of the peri-implant tissue represents the key factor in obtaining a successful result in implantology, since an adequate vascular supply allows wound healing and the presence of numerous growth factors that promote osteogenesis. The aim of this study was to analyse “in vivo” the vascular pattern of the peri-implant mucosa in subjects that received implant treatment. Materials and methods In the study 22 subjects were examined, 11 of whom (test group) received dental implants (Straumann Dental Implant System ® ) while 11 were in the control group; the analysis was performed in the peri-implant masticatory mucosa. The evaluation of the microcirculatio…
Association between marfan syndrome and oral health status : a systematic review and meta-analysis
2019
Background: The purpose was to identify and assess the existing scientific evidence from epidemiologic, non-experimental, observational studies of associations between Marfan’s syndrome and oral diseases. Material and Methods: Electronic literature searches in MEDLINE (OVID), The Cochrane Library, Scopus and the Web of Science were conducted to identify all relevant articles. Eligibility was based on inclusion criteria, and quality assessments were conducted. The outcome variables were probing depth, gingival margin, clinical attachment level, bleeding on probing, gingival status, periodontal status, tooth mobility, furcation involvement and decayed, missing and filled teeth index. After ex…
Effect of aluminum chloride hemostatic agent on microleakage of class V composite resin restorations bonded with all-in-one adhesive
2012
Objectives: Since hemostatic agents can induce changes on enamel and dentin surfaces and influence composite resin adhesion, the aim of the present study was to evaluate the effect of the aluminum chloride hemostatic agent on the gingival margin microleakage of class V (Cl V) composite resin restorations bonded with all-in-one adhesive. Study design: Cl V cavities were prepared on the buccal surfaces of 60 sound bovine permanent incisors. Gingival margins of the cavities were placed 1.5 mm apical to the cemento-enamel junction (CEJ). The teeth were randomly divided into two groups of 30. In group 1, the cavities were restored without the application of a hemostatic agent; in group 2, the ca…
<i>In vitro</i> evaluation of microleakage in Class II composite restorations: High-viscosity bulk-fill <i>vs</i> conventiona…
2019
This study compared marginal microleakage of Class II cavities restored with bulk-fill resin (Filtek™ Bulk Fill) and conventional composite resin (Filtek™ Supreme XTE). Two standardized Class II cavities were prepared in forty extracted human molars. The gingival margin was located above the cemento-enamel junction for twenty molars (groups 1 and 2) and apically for the other twenty (groups 3 and 4) (n=20). The occlusomesial cavity was filled with bulk-fill resin by insertion in bulk (groups 1 and 3) and the occlusodistal cavity was restored with conventional composite using incremental technique (groups 2 and 4). The teeth were thermocycled (500 cycles 5-55°C), stained and observed under l…
Ceramic veneers on central incisors without finish line using bopt in a case with gingival asymmetry
2019
Objectives This clinical case report describes the rehabilitation of central incisors with veneers in a patient with gingival asymmetry. The teeth were prepared without finish line, applying BOPT concepts to correct asymmetry, and obtained a harmoniously integrated restoration with optimal periodontal health. Clinical implications Biologically oriented preparation technique (vertical or “feather edge” preparation) was used to obtain gingival symmetry. Teeth were prepared without horizontal finish line to achieve correct emergence, soft tissue adaptation and stabilization, while maintaining biological space, both at the provisional restoration stage and later when definitive restorations wer…
Altered passive eruption (APE) : a little-known clinical situation
2010
Gummy smile constitutes a relatively frequent aesthetic alteration characterized by excessive exhibition of the gums during smiling movements of the upper lip. It is the result of an inadequate relation between the lower edge of the upper lip, the positioning of the anterosuperior teeth, the location of the upper jaw, and the gingival margin position with respect to the dental crown. Altered Passive Eruption (APE) is a clinical situation produced by excessive gum overlapping over the enamel limits, resulting in a short clinical crown appearance, that gives the sensation of hidden teeth. The term itself suggests the causal mechanism, i.e., failure in the passive phase of dental eruption, tho…
Management of a crown-root fracture : a novel technique with interdisciplinary approach
2018
Anterior teeth with subgingival fractures require a complex treatment plan that addresses biologic, functional and aesthetic factors. This case report describes the management of a crown-root fractured maxillary left central incisor. An interdisciplinary approach was used to restore the tooth due to the complex nature of the treatment. Orthodontic extrusion was performed to move the fracture line above the alveolar bone and periodontal surgery to recontour the altered gingival margin. Finally, the incisor was restored performing a root canal retreatment with a fiber post and a full ceramic crown. The treatment resulted in secured periodontal health and good aesthetics. Key words:Crown-root …
Classification of Gingival Recession
2018
Gingival recession is a common finding in many patients and is clinically manifested by an apical displacement of the gingival margin in relation to the cemento-enamel junction (CEJ). Various classification systems have been proposed to classify gingival recession defects and to predict final root coverage outcomes. Among them, the Miller classification is still the most commonly used among dental practitioners and researchers. This chapter reviews the different classification systems available for gingival recession defects and explores the strengths and limitations of them.
Definition of Gingival Recession and Anatomical Considerations
2018
The gingiva is an integral part of the periodontium that covers the cervical portions of the teeth and the alveolar processes of the jaws. In health, the closely adapted gingival tissues provide effective protection against mechanical trauma and bacterial invasion and also play a critical role in aesthetics. Therefore, a recession of the gingival margin not only affects the aesthetic appearance but may cause several adverse consequences due to exposure of the root surface. This chapter provides a definition of gingival recession and gives a basic overview of the anatomical characteristics of the gingiva. A basic understanding of the macroscopic and microscopic features of healthy gingiva is…
Comparative in vitro study of two methods for gingival biotype assessment
2018
Background The gingival thickness seems to have an important role in different dental treatments. There are different methods of quantifying this thickness, but it is not known which of them can be the most effective. The objective to assess the accuracy of two different methods for gingival thickness measurement: the transgingival needle probing (TGNP) and the tension-free caliper (TFC) in an in vitro model, by comparing them with direct physical measurements (reference standard). Material and methods Gingival thickness (GT) was evaluated in 27 female pigs with four implant sites 1, 2 and 3mm from the gingival margin with three different methods: 1) transgingival needle probing 2) tension-…
