Relationships Between Different Tooth Shapes and Patient’s Periodontal Phenotype
The purpose of the present study was to establish
whether any correlation exists between tooth shapes and patient-related factors such as gingival and periodontal characteristics. Clinical measurements, including the width and the height of maxillary central incisor crowns, the apico incisal height of the keratinized mucosa, the buccal gingival thickness (GT), the depth of the sulcus, the bone-sounding depth (BS) and the height of the interproximal maxillary central papilla, were investigated in 50 healthy individuals. These individuals were then divided into three groups based on the shape of their maxillary central incisor crowns: triangular; square; or square-tapered. The results of this study indicate that different tooth shapes are associated with significantly different values for the extent of the KM, its bucco-lingual thickness and the height of the interproximal maxillary central papilla.
Evaluation of Enamel Micro-Cracks Characteristics After Removal of Metal Brackets in Adult Patients
The purpose of this study was to evaluate and compare enamel micro-crack characteristics of adult patients before and after removal of metal brackets. After the examination with scanning electron microscopy (SEM), 45 extracted human teeth were divided into three groups of equal size. The length and width of the longest enamel micro-crack were measured for all the teeth before and after removal of metal brackets. The changes in the location of the micro-cracks were also evaluated. New enamel micro-cracks were found in 6 of 15 (40 per cent) examined teeth. Greatest changes in the width of enamel micro-cracks after debonding procedure appear in the cervical third of the tooth. On the basis of this result, the dentist must pay extra care and attention to this specific area of enamel during removal of metal brackets in adult patients.
Acellular Dermal Matrix Grafts for Root Coverage Procedures: Review of Products and Introduction of a New Technique
Gingival recession remains a significant problem in dental esthetics as well as periodontal health. Adequate zones of keratinized, attached tissue are vital for long-term periodontal health and maintenance. The correction of gingival recession is an important principle in cosmetic dental procedures that requires a harmonious gingival complex. Correction of deficient gingival tissues by either autogenous or allogenic tissue grafts has been well documented in the literature. This article will delineate differences among the various acellular dermal grafts as well as introduce a new technique that can enhance success.
Surgical Crown Lengthening in a Population With Human Immunodeficiency Virus: A Retrospective Analysis
This report investigates the outcome of CLS procedures performed at an urban dental school in a population of
individuals with HIV. Specifically, this retrospective clinical analysis evaluates the healing response after crown lengthening surgery (CLS). Of the 21 patients with HIV examined after CLS, none had postoperative complications, such as delayed healing, infection, or prolonged bleeding. Variations in viral load, CD4 cell count, smoking, platelets, and neutrophils did not impact surgical healing. In addition, variations in medication regimens
(highly active anti-retroviral therapy; on pro-tease inhibitors; no medications had an impact. The results of this retrospective analysis show the absence of postoperative complications after CLS in this population with HIV. Additional investigation into this area will help health care practitioners increase the range of surgical services provided to this group of patients.
RevitaliZe Patient Solutions: preliminary results from a single cohort prospective study using Screw-Vent TSVT implants
The aim of this paper was to report preliminary results from a cohort of subjects treated with the
RevitaliZe Patient Solutions approach. Clinical and radiographic results of axial and tilted implants up to
fourteen months of loading are presented. Seven patients were followed up for an average
of 11,88 months (range 8-16 months). Five subjects received implant treatment in both arches, resulting in
12 restorations. A total of 48 fixtures were placed and no failure was reported
during the follow-up period, leading to 100% implant and prosthetic survival rates. Radiographic analysis after
6 months of loading was conducted for all prostheses. No significant difference in marginal bone loss was
found between tilted and axial implants in both jaws. The present preliminary data suggests that
immediate loading with RevitaliZe Patient Solutions could be considered a predictable and cost- and timeeffective
approach for the treatment of total edentulism.
