Hereditary gingival fibromatosis: Characteristics and treatment approach
2017
Hereditary gingival fibromatosis (HGF) is a rare disorder characterized by a benign, non-hemorrhagic, fibrous gingival overgrowth that can appear in isolation or as part of a syndrome. Clinically, a pink gingiva with marked stippling can be seen to cover almost all the tooth, in many cases preventing eruption. HGF usually begins during the transition from primary to permanent teeth, giving rise to a condition that can have negative psychological effects at that age. As it does not resolve spontaneously, the treatment of choice is gingivectomy, which can be performed with an internal or external bevel incision, depending on each case and bearing in mind the changes that will take place at th…
Effect of disinfecting the cavity with chlorhexidine on the marginal gaps of Cl V giomer restorations
2017
Background Considering the effect of cavity disinfecting agents on the bonding and sealing ability of restorations bonded to dentin, the aim of this study was to evaluate the effect of chlorhexidine (CHX) disinfecting agent on the marginal gaps of Cl V giomer restorations. Material and Methods Cl V cavities were prepared on the buccal surfaces of 60 sound bovine permanent incisors in this in vitro study, with the occlusal and gingival margins in enamel and dentin, respectively. The teeth were randomly divided into two groups (n=30). The teeth in groups 1 and 2 were restored without and with the use of the disinfecting agent in the cavity, respectively, before applying the adhesive. BeautiBo…
Comparison of the detection of periodontal pathogens in bacteraemia after tooth brushing by culture and molecular techniques
2016
Background: The prevalence and amounts of periodontal pathogens detected in bacteraemia samples after tooth brushing-induced by means of four diagnostic technique, three based on culture and one in a molecular-based technique, have been compared in this study. Material and Methods: Blood samples were collected from thirty-six subjects with different periodontal status (17 were healthy, 10 with gingivitis and 9 with periodontitis) at baseline and 2 minutes after tooth brushing. Each sample was analyzed by three culture-based methods [direct anaerobic culturing (DAC), hemo-culture (BACTEC), and lysis-centrifugation (LC)] and one molecular-based technique [quantitative polymerase chain reactio…
The Efficacy of Powered Oscillating Heads vs. Powered Sonic Action Heads Toothbrushes to Maintain Periodontal and Peri-Implant Health: A Narrative Re…
2021
Objectives: To compare the efficacy of rotating-oscillating heads (ORHs) VS sonic action heads (SAHs) powered toothbrushes on plaque accumulation and gingival inflammation. Methods: An electronic (MEDLINE, Embase, Inspec, PQ SciTech and BIOSIS) and a complementary manual search were made to detect eligible studies. RCTs meeting the following criteria were included: final timepoint longer than 15 days; year of publication after 2000; patients without orthodontic appliances or severe systemic/psychiatric diseases. Studies comparing two or more different types of sonic/roto-oscillating toothbrushes were excluded. Selection of articles, extraction of data, and assessment of quality were made in…
Gingival bleeding reduction using a carbamide peroxide based tooth paste with lactoperoxidase
2011
Introduction: The combination of carbamide peroxide, thiocyanate or enzymes such as amynoglucosidase or gluco-oxidase is able to reduce gingival inflammation. Objective: To evaluate antiseptic efficacy, in relation to reduced gingival bleeding, of a new dentifrice containing carbamide peroxide and lactorperoxidase. Materials and method: A sample of 32 patients, with periodontal pockets of more than 3mm in the vestibular area and 4 mm at interproximal sites, was divided into two groups of 16 and 17 patients respectively. Group A used a dentifrice containing 3% carbamide peroxide and 5% lactoperoxidase plus 0.022% sodium fluoride for three weeks followed by a control dentifrice with only 0.02…
Percepción actual de la estética de la sonrisa
2020
Introducción: La belleza de una sonrisa constituye un sentimiento altamente subjetivo, y por ello los ideales de una sonrisa bonita pueden ser extensamente distintos y variables en la población. El objetivo de este estudio fue determinar los parámetros ideales de algunos componentes de la sonrisa, e igualmente conocer si la percepción estética de los mismos varía según profesionales de la odontología y público general, así como entre diestros y zurdos. Los aspectos de la sonrisa estudiados fueron: escalón vertical entre incisivos central y lateral, exposición gingival, forma de los dientes y desviación de línea media dental tanto hacia el lado derecho como izquierdo. Material y método: La m…
The influence of micronutrients on oral and general health
2011
Abstract Objective The aim of the present clinical pilot study was to examine the influence of a combination of micronutrients on individuals with high stress experience. Methods 40 healthy students (28 female, 12 male) with a mean age of 27.1 ± 3.0 years, experiencing high examination stress, were chosen. After approval of the ethics commission, one group of students (n = 19) took a combination of micronutrients (Orthomol vital m/f) for three months, whereas other students (n = 21) served as control group. All participants underwent at the beginning and at the end of the trial a dental examination, a determination of 10 periodontal pathogens, a salivary and a blood analysis. In addition, t…
Clinical effect of vitamin C supplementation on bone healing: A systematic review
2022
Background: The aim of the present systematic review was to evaluate the clinical effect of vitamin C on bone healing after bone fracture or bone reconstruction procedures. Material and Methods: In October 2020, Cochrane Library, Scopus and PubMed-Medline databases were searched without restrictions to identify animal and human studies that fulfilled the eligibility criteria. Outcome measures were bone healing time, bone gain (mm), bone density and adverse events. The risk of bias assessment of the selected studies was evaluated by means of Cochrane Collaboration's Tool for randomized clinical trials, while randomized clinical animal trials were assessed according to SYRCLE's tool. Addition…
Non-surgical periodontal treatment with a new ultrasonic device (Vectortm-ultrasonic system) or hand instruments. A prospective, controlled clinical …
2004
Objectives: The aim of this prospective, randomized, controlled clinical study was to compare the effectiveness of a newly developed ultrasonic device to that of scaling and root planing for non-surgical periodontal treatment. Material and Methods: Thirty-eight patients with moderate to advanced chronic periodontal disease were treated according to an “one-stage procedure” with either a newly developed ultrasonic device (VUS) (Vector™-ultrasonic system) or scaling and root planing (SRP) using hand instruments. Clinical assessments by plaque index (PlI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), and clinical attachment level (CAL) were made …
Metástasis gingival de adenocarcinoma de colon
2006
La cavidad oral es lugar de asiento de tumores metastásicos, sobre todo con origen en mama y pulmón. La mayoría de los casos afectan por este orden a los huesos mandibular y maxilar, aunque en ocasiones se desarrollan sobre las partes blandas intraorales. Presentamos el caso de un paciente de 62 años diagnosticado de adenocarcinoma de colon sigmoide con metástasis ganglionares y hepáticas, que 6 meses después presenta una lesión vegetante en la encía, interpretada inicialmente como neoplasia primaria de encía, que tras ser biopsiada fue diagnosticada como adenocarcinoma intestinal metastásico. El estudio histológico es obligatorio para diferenciar un adenocarcinoma de los carcinomas de célu…
