Prospective assessment of post-extraction gingival closure with bone substitute and calcium sulphate
2009
Introduction: The closure of post extraction gingival defects has not been studied in depth, although their achievement is of great importance in certain situations, such as prior to radiotherapy treatment in patients with oral cancer. The aim of this study is to assess the influence of bone substitutes on the time of closure of post extraction gingival defects. Materials and Methods: 22 patients underwent two symmetrical dental extractions. Using a split mouth model, with random assignment to one or other group, one was considered a control group (no filling with any type of material post extraction), whereas the other was considered the experimental group (filling with bone substitute and…
Cyclosporin- and nifedipine-induced gingival overgrowth in renal transplant patients: correlations with periodontal and pharmacological parameters, a…
1996
The factors associated with cyclosporin A (CsA)- and nifedipine (Nif)-induced gingival overgrowth were investigated in 113 renal transplant recipients receiving CsA alone (Group 1) [n = 61], CsA and Nif (Group 2) [n = 28], or azathioprine (Aza) (Control Group) [n = 24]. Periodontal and pharmacological parameters were assessed for each patient. The patients with a gingival overgrowth index (GOI) score1 were considered responders (R); those with a score/= 1 were non-responders (NR). Gingival overgrowth occurred in 33.7% of the patients in Groups 1 and 2; 60% of the responders were receiving CsA+Nif. In R, no relationship was found between the GOI and the periodontal and pharmacological parame…
Gingival recession and associated factors in a homogeneous Mexican adult male population : a cross-sectional study
2011
Background: Diverse variables are implicated in the pathogenesis of gingival recession; more detailed knowledge about the relationship between the clinical presentation of gingival recession and assorted risk indicators may lead to improved patient monitoring, early intervention, and subsequent prevention. The objective was to evaluate clinically gingival recession in a homogeneous Mexican adult male population and to determine the strength of association with related factors. Method: A cross-sectional study was carried out in a largely homogeneous group in terms of ethnic background, socioeconomic status, gender, occupation, and medical/dental insurance, in Campeche, Mexico. Periodontal ex…
Marginal soft tissue stability around conical abutments inserted with the one abutment-one time protocol after 5 years of prosthetic loading
2018
BACKGROUND Soft tissue stability is crucial to obtain and maintain optimal esthetic results. PURPOSE This study aimed to investigate, over 5 years, the soft tissue response using a conical abutment together with the "one-abutment one-time" (OA-OT) protocol in the restoration of implants inserted in the anterior esthetic area. MATERIAL AND METHODS From January 2011 to January 2012, all consecutive patients requiring an implant n the maxillary area between canines were enrolled. After submerged healing and osseointegration, a definitive abutment with a provisional crown was inserted. After 1 month, the definitive crown was delivered (Tdef). Analog impressions were taken before tooth extractio…
Failure of endodontic treatment due to a palatal gingival groove in a maxillary lateral incisor with talon cusp and two root canals.
1990
A case is presented in which endodontic treatment of a maxillary lateral incisor with a talon cusp and two root canals failed following a mistaken diagnosis. What was first diagnosed as an endodontic lesion was, in all probability, a primary periodontal lesion caused by the advance of bacteria from the gingival crevice to the apex along the radicular groove between the main tooth and the talon cusp.
Approximal plaque and gingival sulcus bleeding in routine dental care patients: relations to life stress, somatization and depression.
2005
Objectives: Previous research on relations between life stress and periodontal conditions was often based on indicators of periodontal destruction history and stimulus-specific measures of life stress. The present study was undertaken to compare patients showing different degrees of gingival sulcus bleeding with patients without signs of bleeding, using an instrument measuring cognitive impacts of events and assessing reported symptoms of depression and somatization. Additionally the patient groups were compared with regard to dental status and dental visiting behaviour. Analog comparisons were conducted in patients with different degrees of approximal plaque. Materials and Methods: 140 rou…
Periodontal disease and oral hygiene benefits in HIV seropositive and AIDS patients
2008
Objectives: The frequency of gingival and periodontal disease in HIV-seropositive and AIDS patients was investigated in order to evaluate the oral hygiene benefits of using mechanical therapy. Study design: thirty-two consenting HIV-positive patients were examined. Their gingival and periodontal status were evaluated using the Gingival Index and the Simplified Oral Hygiene Index. The data were assessed at baseline, after three months and after six months. Subjects received mechanical therapy, which included calculus removal, scaling and root planning, tooth polishing and oral hygiene instructions. The maintenance of oral hygiene was performed weekly. HIV staging and CD4 counts were also inv…
Fixed dental prostheses with vertical tooth preparations without finish lines: A report of two patients
2016
Tooth abutments can be prepared to receive fixed dental prostheses with different types of finish lines. The literature reports different complications arising from tooth preparation techniques, including gingival recession. Vertical preparation without a finish line is a technique whereby the abutments are prepared by introducing a diamond rotary instrument into the sulcus to eliminate the cementoenamel junction and to create a new prosthetic cementoenamel junction determined by the prosthetic margin. This article describes 2 patients whose dental abutments were prepared to receive ceramic restorations using vertical preparation without a finish line.
Effect of posterior gingival smile on the perception of smile esthetics
2013
Objectives: To evaluate and compare the influence of posterior gummy smile on the perception of smile esthetics by orthodontists, general-dentists and laypersons. Study Design: A frontal photograph of a smile with normal gum exposure was chosen and manipulated digitally using Adobe Photoshop C3 to generate three further images with posterior gum exposure of 4, 6 and 8mm. These four images were assessed by the three evaluator groups: orthodontists (n=40), general-dentists (n=40) and laypersons (n=40). Both orthodontists and dentists had at least ten years professional experience and laypersons were aged between 40-50 years. The proportion of men to women was 20:20 in each group. Evaluators a…
Prevalence of fimA genotypes of Porphyromonas gingivalis and other periodontal bacteria in a Spanish population with chronic periodontitis
2012
Objectives: The aim of this study was to determine the prevalence of the different fimA genotypes of Porphyromonas gingivalis in adult Spanish patients with chronic periodontitis, patients with gingivitis and periodontally healthy subjects, and the relationship between these genotypes and other periodontopathogenic bacteria. Study design: Samples of subgingival plaque were taken from 86 patients (33 with chronic periodontitis, 16 with gingivitis, and 37 periodontally healthy) in the course of a full periodontal examination. PCR was employed to determine the presence of the 6 fimA genotypes of Porphyromonas gingivalis (I-V and Ib) and of Aggregatibacter actinomycetemcomitans, Tannerella fors…
