A combined treatment regimen for desquamative gingivitis in patients with oral lichen planus

2007

Background:  Chronic desquamative gingivitis (DG) is a condition characterized by erythema, ulceration, and desquamation of the free and attached gingiva, usually expression of a district-systemic disease, such as oral lichen planus (OLP). Methods:  A combined protocol of oral hygiene and topic corticosteroid therapy was applied in 30 patients with DG associated with OLP. Plaque index (PI) and bleeding on probing (BoP) were evaluated at baseline and after 3 months. Results:  PI scoring was significantly lower after treatment in anterior, posterior, and all sites (P < 0.0001) as well as in vestibular and lingual ones (P < 0.0001 and P = 0.0001, respectively). BoP measures were found to be re…

Clinical and Microbiologic Effects of Subgingival Controlled-Release Delivery of Chlorhexidine Chip in the Treatment of Periodontitis: A Multicenter …

2008

Background: The main therapeutic approach for periodontal diseases is mechanical treatment of root surfaces via scaling and root planing (SRP). Multicenter clinical trials have demonstrated that the adjunctive use of a chlorhexidine (CHX) chip is effective in improving clinical results compared to SRP alone. However, some recent studies failed to confirm these clinical results, and conflicting results were reported regarding the effects of the CHX chip on subgingival microflora. The aim of this study was to provide further data on the clinical and microbiologic effects of CHX chips when used as an adjunct to SRP. Methods: A total of 116 systemically healthy individuals with moderate to adva…

Proliferative verrucous vs conventional leukoplakia: no significantly increased risk of HPV infection

2004

Proliferative verrucous leukoplakia (PVL) is a very aggressive form of oral leukoplakia (OL) with high morbidity and mortality rates, hypothesised to be linked to HPV infection. This study aimed to determine the presence of HPV DNA in PVL in comparison with OL, and in relation to social-demographical variables (age, gender, smoking and drinking habits) in an Italian multi-centric hospital-based study. The study group consisted of 58 cases of PVL and 90 cases of OL as controls (47 homogeneous (H) and 43 non-homogeneous (non-H) form), both recruited from four Italian cohorts. HPV DNA was identified in exfoliated mucosal cells by nested PCR (nPCR) with MY09/MY11 and GP5+/GP6+ primer pairs and …

Brushing of Oral Mucosa for Diagnosis of HPV Infection in Patients with Potentially Malignant and Malignant Oral Lesions

2006

Introduction: Adequate brushing of oral mucosa is important for accurate human papillomavirus (HPV) detection in potentially malignant (oral leukoplakia [OL], oral lichen planus [OLP]) and malignant (oral squamous cell carcinoma [OSCC]) lesions. Since various factors may limit the adequacy of oral brushing and, consequently, the accuracy of HPV detection, modified sampling procedures should be evaluated for their effect on HPV frequency and/or types detected. Aim: To compare the HPV frequency in samples obtained by brushing the lesion site with the frequency in samples obtained by brushing an apparently normal adjacent site. The correlation between HPV frequency and keratinization of the si…

HPV infection in relation to OSCC histological grading and TNM stage. Evalutation by traditional statistics and fuzzy logic model

2006

We aimed to evaluate if in oral squamous cell carcinoma (OSCC) there is a relationship between histological grading (HG), TNM clinical stage and HPV infection; and to study the performance of fuzzy logic compared to traditional statistics, in the analysis of HPV status and correlates of OSCC. In cross-sectional analysis, the study group comprised 63 patients (mean age 68.89 years (SD ± 11.78), range (32–93); males 28 (44.4%), females 35 (55.6%)) with OSCC histologically diagnosed. HPV-DNA was studied in exfoliated oral epithelial cells by nested PCR (MY09/MY11 and GP5+/GP6+ primers). Data were analysed in parallel by traditional statistics with multivariate analysis and a fuzzy logic (FL) t…

Low rate of oral human papillomavirus (HPV) infection in women screened for cervical HPV infection in Southern Italy: A cross-sectional study of 140 …

2009

Even though the natural history of cervical and oral human papillomavirus (HPV) infection has been investigated intensely, the possibility that HPV may infect both sites in the same subject is not well documented. This study investigated the frequency of concurrent oral and cervical HPV infection in southern Italian women, in the light of some selected socio-behavioral variables. One hundred forty women (mean age: 36 years), with known cervical HPV status, were analyzed for oral HPV. Age, smoking/drinking habits, clinical and socio-behavioral history were assessed by personal interviews. Oral mucosal cells were collected by oral brushing and HPV DNA was sought by the use of nested PCR ampli…

The effects of antimicrobial sprays and mouthrinses on supragingival plaque regrowth: a comparative study.

2006

BACKGROUND: Due to the side effects of chlorhexidine digluconate (CHX) mouthrinsing, a spray has been proposed as an alternative method of CHX delivery to the oral cavity. The aim of this study was to investigate the plaque inhibitory effects of CHX, cetylpyridinium chloride (CPC), and triclosan (TRN) delivered by sprays and mouthrinses. METHODS: The study was an observer-masked, randomized cross-over design balanced for carryover effects, involving 15 healthy volunteers in a 4-day plaque regrowth model. Products being tested (0.2% CHX, 0.12% CHX, 0.05% CPC, and 0.03% TRN) were used both as sprays and mouthrinses. A saline solution served as a negative control. On day 1, subjects received p…

Expression of cell cycle markers and human papillomavirus infection in oral squamous cell carcinoma: use of fuzzy neural networks.

2005

Our aim was to evaluate in oral squamous cell carcinoma (OSCC) the relationship between some cell cycle markers and HPV infection, conditionally to age, gender and certain habits of patients, and to assess the ability of fuzzy neural networks (FNNs) in building up an adequate predictive model based on logic inference rules. Eighteen cases of OSCC were examined by immunohistochemistry for MIB-1, PCNA and survivin expression; presence of HPV DNA was investigated in exfoliated oral mucosa cells by nested PCR (nPCR, MY09-MY11/GP5-GP6), and HPV genotype was determined by direct DNA sequencing. Data were analyzed by traditional statistics (TS) and FNNs. HPV DNA was found in 9/18 OSCCs (50.0 %) wi…

Genotyping and antifungal susceptibility of human subgingival Candida albicans isolates.

2002

Subgingival colonization by Candida albicans has been described in human immunodeficiency virus (HIV)-infected individuals, but subgingival isolates have scarcely been characterized, particularly with respect to genotype and antifungal susceptibility. A series of 29 subgingival strains of C. albicans isolated from nine HIV-infected individuals was typed by electrophoretic karyotyping and tested for susceptibility to fluconazole, itraconazole, the new investigational triazole posaconazole and amphotericin B. DNA typing showed genetic heterogeneity within subgingival isolates, as almost every individual harbored his/her own specific isolate. Genetic identity was usually demonstrated within or…

Malattia parodontale e malattia cardiovascolare: correlazione o semplice coincidenza? Revisione della letteratura

2007

The present paper reviews relationship between chronic periodontitis and cardiovascular diseases. Original papers on this subject, published in English in the period between 2001 and the first semester 2006, were located in the MEDLINE/PubMed database. Additional studies were obtained by searching reference lists of previously published papers. Periodontal infection provides a chronic reservoir of inflammatory mediators and cytokines, lipopolysaccharide, which contribute to the formation of atheroma. Moreover, periodontal pathogens can penetrate the epithelial barrier of the periodontal tissues and reach the blood stream, carrying out a local atherogenic activity. Some studies indicated tha…

Treatment of prepubertal periodontitis. A case report and discussion.

1992

Abstract This paper reports the treatment of prepubertal periodontitis in a 3–year-old girl with Papillon-Lefevre Syndrome. Initially, the patient was found to have a myeloperoxidase deficiency and microbiological tests have identified Bacteroides and Fusobacterium, in 60% and 25%, respectively of the total number of microbial flora cultivated. The initial treatment was extraction of all the primary teeth with grade 3 mobility, scaling, root planing and daily subgingival irrigation with a 0.2% solution of chlorhexidine. Several months before the eruption of the first permanent molars, the rest of the primary teeth were extracted. The patient was treated with daily subgingival irrigation of …

No findings of dental defects in children treated with minocycline

2004

Thanks to their broad antimicrobial spectrum, tetracyclines were found to be valuable for the treatment of many infections (10). Unfortunately, they irreversibly bind to calcifying tissues and are deposited along the incremental lines of dentine and enamel, causing defects and staining, from bright yellow to dark brown (3, 5, 8). According to the American Academy of Pediatrics, tetracyclines are not indicated for the treatment of common infections in children younger than 8 years of age. However, doxycycline (a tetracycline analogue) is recommended for treatment of Rocky Mountain spotted fever in children of any age (1). Minocycline has several advantages over other tetracyclines: it is bet…

Occurrence of invading bacteria in radicular dentin of periodontally diseased teeth: Microbiological findings

1997

Bacterial invasion in roots of periodontally diseased teeth, which has been recently documented using cultural and microscopic techniques, may be important in the pathogenesis of periodontal disease. The purpose of this investigation was to determine the occurrence and the species of invading bacteria in radicular dentin of periodontally diseased teeth. Samples were taken from the middle layer of radicular dentin of 26 periodontally diseased teeth. 14 healthy teeth were used as controls. Dentin samples were cultured anaerobically. The chosen methodology allowed the determination of the numbers of bacteria present in both deeper and outer part of dentinal tubules, and the bacterial concentra…
