Oral microcirculation in post-menopause: a possible correlation with periodontitis

2012

Objectives: The reduction in the level of oestrogen, typical in menopause, has some effect on the health of the oral cavity. In fact, post-menopausal women present more severe periodontal disease than pre- menopausal women. Numerous factors can be held to be responsible for this increase, among which are the effects of oestrogens on the oral epithelium, on the salivary glands, on bone tissue and on the endothelium. Our double blind study aims to evaluate the possible variations in oral microcirculation in post-menopausal women. Methods: Twenty-seven women in post-menopause (age: Mean ± SD: 57.3 ± 8.73) and 27 women in pre-menopause (age: Mean ± SD: 27.77 ± 3.56) were examined. Oral microcir…

Study of the microcirculation of oral mucosa in healthy subjects

2003

The research has the following aims: 1: to verify the applicability of capillaroscopic investigation to oral mucosa; 2: to propose oral mucosa as an alternative to the fingernail fold for capillaroscopic investigation; 3: to describe the characteristics of the microcirculation of oral mucosa in healthy subjects. 100 healthy patients were examined. The characteristics of the micro-circulation in the areas of gum mucosa and the mucosa covering of the lower lip were examined using computerised videomicroscopic techniques. For each patient we evaluated the visibility, the course, the density, the tortuosity and any images characteristic of capillary loops, besides the possible presence of micro…

STUDY OF MICROCIRCULATION IN ORAL LICHEN PLANUS BY VIDEOCAPILLAROSCOPY

2007

Objective. The aim of this study was to evaluate “in vivo” the oral microcirculatory characteristics in patients with oral lichen planus (OLP) and to discover any differences in microcirculation in comparison with healthy patients. Study design. Twenty patients with established diagnosis of OLP and 20 healthy patients were examined in our laboratory by means of contact optical probe videocapillaroscopy. The examined areas for each patient were the right and the left buccal mucosae. Capillary density and total capillary diameter, as well as afferent and efferent loop diameter were studied; the discovery of characteristic (tortuous, branched) loops was also investigated. Results. The results …

ORAL MICROVASCULAR ABNORMALITIES IN PATIENTS WITH RHEUMATOID ARTHRITIS

2006

Microvascular involvement represents one of the first apparent steps in many autoimmune diseases such as rheumatoid arthritis (RA). Early in the disease, peripheral microangiopathy may be easily recognized and studied by videocapillaroscopy. The aim of this study has been to observe the differences in labial microcirculation between healthy patients and patients suffering from RA. A total of 30 healthy patients and 30 patients suffering from RA were examined. The patients with conditions known to compromise microcirculation, such as diabetes, hypertension, or some pharmacological treatments were not included in the study. All the patients were non-smokers. Labial capillaroscopy was used to …

The effect of acupuncture on oral microcirculation in healthy volunteers: an exploratory study.

2009

Background Acupuncture is a therapeutic technique currently used in the treatment of many pathologies. The aim of this study is to evaluate the potential effect of acupuncture on “in vivo” variations in oral microcirculation in healthy subjects. Methods An exploratory study was conducted on 40 healthy subjects: 20 cases (mean 55.90, SD 16.04) and 20 controls (mean 51, SD 11.91). Videocapillaroscopy was used to detect variations in oral microcirculation. This method permits an accurate and non-invasive in vivo study of the capillaries of the oral mucous. The site selected for this pilot study is the lower lip since it is the simplest to investigate and is more readily accessible. Assessments…

Changes of oral microcirculation in chemotherapy patients: A possible correlation with mucositis?

2014

The aim of this investigation is to appraise labial oral microcirculation in chemotherapy patients to clarify the effects of cytotoxic agents on oral microvessels. Twenty-five patients with diagnosis of head and neck tumors were recruited in the study. All the patients were submitted to chemotherapy. Labial oral microcirculation was evaluated on labial mucosa using oral videocapillaroscopy. The statistical significance was checked with the Mann-Whitney U-test (P < 0.05). The analysis of videocapillaroscopic patterns showed statistically significant variations relative to the diameter of the incoming loop; the diameter of the outgoing loop; and loop tortuosity. This study shows that capillar…

MORPHOLOGIC CHANGES IN THE MICROCIRCULATION INDUCED BY CHRONIC SMOKING HABIT: A VIDEOCAPILLAROSCOPIC STUDY ON THE HUMAN GINGIVAL MUCOSA

2005

PURPOSE: To analyze the gingival characteristics of microcirculation in vivo and to evaluate the effects of smoking by means of computerised videocapillaroscopic techniques. METHODS: 35 healthy non-smokers and 35 healthy smokers were examined. The characteristics of gingival microcirculation were examined using computerized videomicroscopic techniques. For each subject, visibility, course, tortuosity and any images characteristic of capillary loops, besides the possible presence of microhemorrhages, the average caliber of the capillary loops and the number of capillary loops visible per square millimeter were evaluated. The investigation was non-invasive and repeatable for each subject. RES…

Oral Microcirculation: Videocapillaroscopy Versus Other Techniques

2009

Microcirculation in the healing of surgical wounds in the oral cavity.

2013

Abstract. The aim of this research is to evaluate in vivo the characteristics of microcirculation after taking a biopsy sample from the oral mucosa. 20 patients were recruited to the study and all underwent an oral mucosa biopsy for the excision of benign neoformations. The modifications in the oral microcirculation were evaluated in vivo in correspondence to the surgical site through videocapillaroscopy at three different times: 30 min before the biopsy; 48 h after the biopsy; and 7 days after the biopsy. The statistical significance was checked with the Mann–Whitney U-test (P < 0.05). The analysis of videocapillaroscopic patterns showed statistically significant variations relative to the…
