Fluoride - an adjunctive therapeutic agent for periodontal disease? Evidence from a cross-sectional study

2008

Objective: To assess the influence of the water fluoride level on periodontal status, by determining the periodontal health status of subjects residing in low, optimum and high fluoride areas. Study design: A cross sectional survey was carried out on 967 adults aged 35-44 years old, from the Udaipur district of India. A stratified cluster random sampling technique was implemented in order to collect a representative sample from low (3ppm) areas, based on the fluoride concentration in drinking water. Periodontal status was assessed in accordance to WHO criteria. The Chi-square test was used to compare proportions, and logistic regression analysis was used to determine the contribution of wat…

Evaluation of Support in Singing

2005

Summary This study searched for perceptual, acoustic, and physiological correlates of support in singing. Seven trained professional singers (four women and three men) sang repetitions of the syllable [pa:] at varying pitch and sound levels (1) habitually (with support) and (2) simulating singing without support. Estimate of subglottic pressure was obtained from oral pressure during [p]. Vocal fold vibration was registered with dual-channel electroglottography. Acoustic analyses were made on the recorded samples. All samples were also evaluated by the singers and other listeners, who were trained singers, singing students, and voice specialists without singing education (a total of 63 liste…

Detection of Epstein-Barr virus (EBV) DNA and antigens in oral mucosa of renal transplant patients without clinical evidence of oral hairy leukoplaki…

1998

The use of the polymerase chain reaction (PCR) to detect the presence of Epstein-Barr virus (EBV) DNA in oral mucosa in the absence of specific lesions gives rise to the problem of identifying the real viral replication sites. To verify whether the detection of EBV is due to salivary contamination or its true replicative capacity in oral mucosa, saliva samples and exfoliated cells from four different oral mucosa sites were taken from 40 renal transplant patients and 20 normal subjects for examination by PCR using two pairs of primers specific for the BamHI-L and BamHI-K genomic regions. EBV-specific sequences were detected in one or more of the oral mucosa samples from 29 transplant patient…

A survey of oral surgeons tobacco-use-related knowledge and intervention behaviors

2012

Objectives: To evaluate whether oral surgeons are aware of tobacco’s role in oral health. Moreover, we wanted to know professionals’ attitudes towards smoker patients and physicians’ involvement in detecting and eradicating this habit in patients. Study Design: We conducted a survey to determine the awareness of the members of the Spanish Society of Oral Surgery about tobacco’s damage on oral health and the role of dentists in the prevention and elimination of the smoking habit. Results: 450 surveys were distributed during the Seventh National Congress of the Spanish Society of Oral Surgery, of which 224 (49.8%) were answered. Seventy-six point eight percent of oral surgeons said that they …

Epstein Barr Virus detection and latent membrane protein 1 in oral hairy leukoplakia in HIV+ Venezuelan patients

2008

Purpose: To determine the prevalence of Epstein Barr Virus (EBV) in oral hairy leukoplakia lesions (OHL) in HIV+ Venezuelan patients. Material and Method: In this case study, we evaluated 21 HIV+ adult patients with clinically present OHL lesions, 11 who were undergoing antiretroviral therapy, 10 who were not undergoing therapy and 10 HIV-negative adult patients with hyperkeratotic oral mucosal lesions. All of the subjects were assessed at the Infectious Disease Center, Faculty of Dentistry, Central University of Venezuela, and were clinically examined to detect oral mucosal lesions with the confirmed histopathologic diagnosis. Nested-PCR was used to determine the EBV infection and the late…

Epstein-Barr virus is not detected in mucosal lichen planus

2018

Background Lichen planus (LP) is a chronic inflammatory, immunological, mucocutaneous disease can affect skin, genital and oral mucosa. Oral lichen planus (OLP) is the most common noninfectious, chronic inflammatory oral disease affecting 1-2% of the general adult population. World Health Organization (WHO) classifies OLP as a potentially malignant disorder. Epstein Barr virus or human herpesvirus-4, is a member of the herpes virus family and one of the most ubiquitous viruses known to human, infecting approximately 90% of the world’s adult population. The virus often infects B lymphocytes resulting in a wide spectrum of mucocutaneous and systemic diseases, ranging from mild lesions to aggr…

High prevalence of human cytomegalovirus in a population of periodontally healthy subjects.

2008

Background: Human cytomegalovirus (HCMV) appears to be more frequent in periodontally affected patients than in healthy control groups. Based on this assumption, it has been suggested that HCMV may play a role in the pathogenesis of periodontal disease. Objective: The objective of this uncontrolled study was to assess the occurrence of HCMV in a large unselected population of periodontally healthy subjects. Study Design: Fifty consecutive periodontally healthy patients satisfied the inclusion criteria. Two samples of gingival crevicular fluids were taken from two non-bleeding on probing sites for each patient. Samples were collected from the anterior and the posterior area. Polymerase chain…

Survival rates and bone loss after immediate loading of implants in fresh extraction sockets (single gaps). A clinical prospective study with 4 year …

2016

Background The aim of this prospective study was to report the outcome of treatment with implants inserted after tooth extraction and immediately loaded. Material and Methods Fifty-six patients with single tooth loss were treated with 116 IPX Galimplant® implants with internal connections and a sandblasted, acid-etched surface. All implants were placed after tooth extraction using a flapless approach without bone regeneration, and they were then immediately loaded with cemented acrylic prostheses. After a period of three months, definitive cemented ceramic prostheses were placed. Patients were examined throughout a total of 4 years of follow-up. Marginal bone loss and survival rates were ev…

Effect of implant macro-design on primary stability: A prospective clinical study

2016

Background Implant restorations have become a high predictable treatment option. Several caracteristics such as surgical technique and implant design can influence the treatment outcomes. The aim of the present study was to evaluate the influence of implant macro-design on primary stability measured with resonance frequency analysis (RFA) and insertion torque (IT). Material and Methods A total of 47 implants divided in two groups: Test group (TI): 22 Tapered MIS® Seven implants; Control group (CI): 25 cylindrical Astra® Osseospeed implants. All implants were inserted following the manufacturers’ standard protocols. Implant primary stability was measured at the moment of implant placement by…
