Evaluation of gingival microcirculation in patients undergoing fixed orthodontic treatment: a pilot study.

2014

AIM: Among the many biological effects which occur during orthodontic movement, we decided to investigate gingival microcirculation. The aim of the study was to evaluate the biological microvascular response to the application of orthodontic force in vivo. MATERIALS AND METHODS: Forty patients (case group) between 9-22 years of age (average± DS 12±3.01) were selected for the study (M/F ratio: 20/20). They needed fixed orthodontic treatment due to several types of malocclusion. Forty healthy subjects (control group) were also recruited (M/F ratio 20/20; average age 12 years ± 4.01; Mean±SD =10.04±1.7). A videocapillaroscopic examination was performed on each patient on the buccal alveolar mu…

Morphological characteristics of microcirculation in oral lichen planus involving the lateral border of the tongue.

2009

Oral lichen planus (OLP) is a chronic mucosal condition commonly encountered in dental practice. Lichen planus is believed to represent an abnormal immune response in which epithelial cells are recognized as foreign, secondary to changes in the antigenicity of the cell surface. It has various oral manifestations. The aim of the study was to evaluate the morphological characteristics of microcirculation of lingual lichen planus (LLP). Twenty patients (10 patients with LLP and 10 healthy patients) were examined by means of videocapillaroscopy. The left margin of the lingual mucosa was examined in each patient. The capillary loop length, loop diameter, and capillary density were analyzed on ev…

In vivo evaluation of labial microcirculation in diabetics: a comparison with healthy subjects.

2011

AIM: Diabetes mellitus, a systemic chronic disease considered an epidemic by the World Health Organization (WHO) due to the rate of increase in the prevalence of diabetes, is a cause of microvascular and macrovascular complications leading to a significant burden for the individual and society. The aim of this study was to evaluate in vivo the effects of type II diabetes mellitus on the microcirculation of oral mucosa. METHODS: Forty-six subjects, 23 patients with type II diabetes mellitus (10 men, 13 women) and 23 healthy patients (9 men, 14 women) were examined in our laboratory. Oral microcirculation was evaluated on labial mucosa using oral video-capillaroscopy: a diagnostic method that…

Abnormal Nailfold Capillaries in Patients after Hand Transplantation

2020

Background: The development of graft vasculopathy may play a role in the long-term deterioration of hand grafts. The aim of study was to examine the patterns of the nailfold capillaries in hand transplant recipients. Methods: the study was performed on six patients who received hand transplantation. To normalize for the effect of immunosuppression an age- and sex-matched group of 12 patients with active kidney transplant was selected. As an additional control group, 12 healthy volunteers were recruited. Nailfold videocapillaroscopy was performed in all participants. Additionally, serum concentrations of vascular endothelial growth factor (VEGF) were measured. Results: Videocapillaroscopic e…

Aortic root dilation in associated with the reduction in capillary density observed at nailfold capillaroscopy in SSc patients

2020

Systemic sclerosis (SSc) is an autoimmune disease characterized by endothelial dysfunction and fibroblasts activation. Microvascular disease may be easily observed by means of nailfold capillaroscopy. Recent evidences emphasized also the involvement of large-medium arteries in SSc, mainly in terms of increased stiffness of the vessel wall. The study aims to measure aortic root diameter in a cohort of SSc patients and to correlate echocardiographic findings with the capillaroscopic pictures. We analyzed the clinical records of 125 consecutive SSc patients (M/F 14/111, mean age 55 ± 12.7 years, median disease duration 11 years) referring in 3 second-level rheumatology centers. All subjects un…

Evaluation of the Oral Microcirculation in Patients Undergoing Anti COVID-19 Vaccination: A Preliminary Study

2022

Videocapillaroscopy allows the study of both the morphological and architectural structure of the microcirculation and its hemodynamic conditions; these parameters are directly involved in autoimmune and/or inflammatory pathologies. The purpose of this research, based on capillaroscopy, is to establish whether a patient who receives an anti-COVID 19 vaccine has any changes in their oral microcirculation. A complete capillaroscopic mapping of the oral cavity of the subjects examined was made; the investigated mucosa sites were the following: cheek, labial, chewing-gingival and back of the tongue. This study showed an increase in capillary density from the comparison between the mean labial c…

Oral microcirculation observed in vivo by videocapillaroscopy: a review

2009

Capillaroscopy is a non-invasive diagnostic technique that is fundamental in viewing peripheral circulation and in studying microangiopathies. The morphological study of microcirculat ion is of fundamental importance, mainly because the microvascular bed is directly involved in the etiopathogenesis of autoimmune disorders and acute and chronic inflammatory pathological conditions. The value of capillaroscopic investigation as a diagnostic means in cases of peripheral microcirculation disorders has been confirmed by numerous studies. Other studies used capillaroscopic investigations to evaluate microcirculation damage not as a complication of disease (diabetes), but as its initial stage, and…

A comparison between nailfold capillaroscopy patterns in adulthood in juvenile and adult-onset systemic sclerosis: A EUSTAR exploratory study.

2015

Objective: Qualitative capillaroscopy patterns in juvenile- and adult-onset systemic sclerosis (SSc) were studied in adulthood using data from the EULAR Scleroderma Trials and Research (EUSTAR) database. Methods: Data collected between June 2004 and April 2013 were examined with focus on capillaroscopy. In this retrospective exploratory study, series of patients with juvenile-onset SSc were matched with series of adult-onset SSc having the same gender and autoantibody profile. Results: 30 of 123 patients with juvenile-onset and 2108 of 7133 with adult-onset SSc had data on capillaroscopy. Juvenile-onset SSc showed scleroderma pattern more frequently than adult-onset SSc (93.3% and 88%). The…
