Microvascular Characteristics of the Human Interdental Papilla
2007
The aim of this study was to observe the microcirculation characteristics of the human interdental papilla in healthy patients in vivo. Twenty healthy patients were examined. Capillaroscopy was used to investigate the characteristics of microcirculation of the human periodontal mucosa. Visibility, course, tortuosity, as well as the average caliber of the capillary loops and the number of visible capillary loops per square millimeter were evaluated for each patient. The investigation of gingival mucosa revealed capillary loops with a course both parallel and perpendicular to the surface. Our study has pointed out that capillaroscopy is a reliable method to study periodontal microcirculation …
Bovine pericardium based non-cross linked collagen matrix for successful root coverage, a clinical study in human
2012
Abstract Introduction The aim of this study was to clinically assess the capacity of a novel bovine pericardium based, non-cross linked collagen matrix in root coverage. Methods 62 gingival recessions of Miller class I or II were treated. The matrix was adapted underneath a coronal repositioned split thickness flap. Clinical values were assessed at baseline and after six months. Results The mean recession in each patient was 2.2 mm at baseline. 6 Months after surgery 86.7% of the exposed root surfaces were covered. On average 0,3 mm of recession remained. The clinical attachment level changed from 3.5 ± 1.3 mm to 1,8 ( ± 0,7) mm during the observational time period. No statistically signifi…
Oral health survey of the adult population of the Valencia region (Spain).
2009
Objectives: Ascertain the oral health status of the adult population in the Valencia region of Spain. Study design: A cross sectional prevalence study was conducted on a sample of 1264 adults, comprising 733 individuals aged 35-44 years and 531 individuals aged 65-74 years. Data collection was carried out in 2006. In both age groups (younger adults and older adults), the clinical examinations were carried out by calibrated dentists (Kappa >0.76). Results: The caries prevalence in the group of 35-44 year-old subjects was 92.2% (DMFT=7.64). In the group of 65-74 year-old subjects, it was 98.3% (DMFT=16.38). The F/DMFT percentage of the younger adults was 66% and that of the older adults was 1…
Association Between Clinical and Microbiologic Cluster Profiles and Peri-implantitis
2017
Purpose: The correlation between associated local factors and peri-implantitis remains unknown. The aim of this study was to investigate the association between the clinical and microbiologic profiles and periimplantitis to eventually categorize different groups of this disease. Materials and Methods: Subjects with at least one implant presenting signs of peri-implantitis were selected. The clinical, radiographic, occlusal, and microbiologic profiles of these infected implants were collected. Cases were classified into five peri-implantitis groups according to potential disease-triggering factors: surgically, prosthetically, biomechanically, purely plaque-associated, and a combination of th…
PERIODONTAL MICROCIRCULATORY ABNORMALITIES IN PATIENTS WITH SYSTEMIC SCLEROSIS
2005
BACKGROUND: The aim of this study was to observe the differences in periodontal microcirculation between healthy patients and patients with systemic sclerosis (SSc). METHODS: Fifteen healthy patients and 15 patients with SSc were examined. Periodontal capillaroscopy was used to investigate the characteristics of microcirculation. The visibility, course, tortuosity, possible presence of microhemorrhages, average caliber of the capillary loops, and number of visible capillary loops per square millimeter were evaluated for each patient. RESULTS: The investigation was simple, non-invasive, and repeatable for each patient. In patients with SSc, it was possible to observe a reduced number of capi…
Periodontal microcirculation in diabetics: An in vivo non-invasive analysis by means of videocapillaroscopy
2012
Summary Background Diabetes mellitus is today considered a society-wide disease of a chronic/degenerative nature. Among the secondary effects of diabetes, the one that interests the dental surgeon most is diabetic parodontopathy. The aim of this study was to underline and objectify microcirculatory variations at a periodontal mucous level in type 2 diabetics. Material/Methods The study enrolled 80 subjects: 40 subjects with a diagnosis of diabetes mellitus type II (18 males and 22 females, between 44 and 85 years of age); and 40 healthy subjects (17 males and 23 females, between 44 and 78 years of age). All the subjects, both diabetic and healthy, were submitted to a videocapillaroscopic ex…
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…
The impact of mastication, salivation and food bolus formation on salt release during bread consumption
2014
Health authorities recommend higher fibre and lower salt content in bread products. However, these basic ingredients of bread composition are multifunctional, and important changes in their content influence the texture, flavour and acceptability of the product. This study was designed to investigate the link between oral processing, bolus formation and sodium release during the consumption of four different breads that varied in composition and structure. Chewing behaviour was determined by surface electromyography, and salivation was quantified from the water content of the boluses collected. The kinetics of bread degradation during food bolus formation was characterised by measuring the …
Periodontal disease and sjogren syndrome: a possible correlation?
2009
Sjögren syndrome (SS) is a chronic autoimmune rheumatic disease characterized by a progressive lymphocytic infiltration of exocrine glands, especially salivary and lachrymal ones, leading to xerostomia, parotid gland enlargement, and xerophthalmia. The aim of this study is to describe the capillaroscopic pattern of the interdental papilla in patients with SS and to evaluate a possible correlation with periodontal disease. Methods: A total of 25 patients affected by SS and 25 healthy controls were examined. The patients with conditions that compromise microcirculation, such as diabetes, hypertension, hyperlipidemia, or some pharmacological treatments, were not included in the study. All the…
Effect of non-surgical periodontal treatment with or without doxycycline on the periodontium of type 1 diabetic patients
2005
Aim: The present investigation was performed to study how type 1 diabetics responded to non-surgical periodontal treatment with and without adjunctive doxycycline. Method: Sixty diabetic type 1 patients (mean age 35.3 +/- 9 years) with moderate-to-severe periodontal disease were selected and divided into two groups of 30 patients each. Both groups were sex and age matched and had similar amounts of periodontal destruction. Plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment levels (CAL) were recorded. Group 1 (30 patients) was treated with oral hygiene instruction, scaling and root planing, chlorhexidine rinses twice a day and doxycycline (100 mg/day for…
