A practical clinical recording system for cases of desquamative gingivitis

Gingival Manifestations in Oral Chronic Autoimmune Bullous Diseases: A Retrospective Study

Background and Objectives: Desquamative gingivitis (DG) is a clinical term indicating "peeling gums" and is associated with different oral manifestations. In this study, we aimed to assess the association between DG and autoimmune blistering mucocutaneous diseases (ABMD) with oral manifestations. Materials and Methods: A retrospective study including 88 patients diagnosed between 1998 and 2019 with ABMD (intraepithelial and subepithelial autoimmune blistering diseases) was performed at the Oral Medicine Department, Faculty of Dentistry, "Carol Davila" University of Medicine and Pharmacy in Bucharest. For each patient, the sociodemographic and anamnestic data, as well as clinical features of oral lesions (location), histological evaluation, and direct immunofluorescence data were collected. Results: Most of the patients involved in the study were female (78.4%). In total, 34 patients (38.63%) were diagnosed with subepithelial autoimmune diseases (SAD) and 54 (61.36%) had intraepithelial autoimmune diseases (IAD). Differences in the anatomic distribution of oral involvement were found between SAD and IAD. The presence of DG was significantly more common in patients with SAD compared to those with a diagnosis of IAD. Conclusions: Specific anatomical locations of the oral lesions are significantly associated with different subtypes of ABMD, with gingiva and hard palate mucosa being more involved in SAD and the soft palate and buccal mucosa in IAD. Desquamative gingivitis is a clinical sign that raises diagnostic challenges for several conditions in oral medicine.

Population-based cohort study to assess the gingival lesions in 1319 patients with lichen planus

AIMS

Oral lichen planus (OLP) is a chronic immune disease. In this paper, we evaluated the overall characters, clinical presentation, and outcome of gingival lesions in OLP Italian patients.

METHODS AND RESULTS

A retrospective cohort study was accomplished: a total of 1319 charts were investigated, of whom 922 were female (69.9%): 617 patients (46.8%) manifested white lesions and 702 red ones (53.2%). While most patients had several oral sites of involvement, the gingiva was the unique location in 103 cases. Symptoms were reported in 480 patients (36.4%): 286 patients with erosive OLP, 103 with atrophic form, and 91 with a white form. Long-lasting surveillance showed that only 40 patients (3.03%) had a total clinical signs remission. Regarding OLP medical treatment provided, patients attending less frequently a dental office underwent more often a specific therapy.

CONCLUSIONS

To the best of our knowledge, this is the biggest collections of patients with gingival OLP ever described; exclusive gingival lesions are, however, rare and unlikely to undergo a malignant transformation. Moreover, gum lesions seemed to anticipate the appearance of oral lesions and a higher rate of OLP therapy was observed in patients with less frequent dental check-ups and oral hygiene instructions.

Efficacy and safety of a bioadhesive gel containing propolis extract, nanovitamin C and nanovitamin E on desquamative gingivitis: a double-blind, randomized, clinical trial

OBJECTIVES

To evaluate the efficacy of a gel-containing propolis extract, nanovitamin C, and nanovitamin E as adjuvants to professional plaque removal on desquamative gingivitis (DG).

MATERIALS AND METHODS

A randomized clinical trial was conducted on patients suffering DG due to mucocutaneous diseases. Patients received professional supragingival prophylaxis with oral hygiene instructions and were randomly assigned to use test or control gels as toothpaste and to apply it on DG lesions 3 times/day for 4 weeks. DG clinical score (DGCS), clinical periodontal variables, and visual analog scale (VAS) for pain and oral health impact profile (OHIP-14) were collected at baseline, 2 and 4 weeks.

RESULTS

Twenty-two patients were randomly assigned to test (n = 11) or control group (n = 11). Eighteen had diagnosis of oral lichen planus and four of mucous membrane pemphigoid. DGCS statistically decreased in both groups after treatment with no significant differences between groups. Clinical periodontal outcomes decreased in both groups, but no significant differences were observed. Periodontal variables statistically improved only in test group after treatment. VAS and OHIP-14 scores decreased in test and control groups without significant differences. However, only one test group showed a statistically significant decrease in VAS and OHIP-14 scores after treatment. No adverse effects were reported.

CONCLUSIONS

Test gel may alleviate DG and improve quality of life without side effects.

CLINICAL RELEVANCE

A gel-containing propolis extract, nanovitamin C, and nanovitamin E as adjuvants to mechanical debridement may improve both clinical and patient related outcomes in DG patients without side effects.

CLINICAL TRIAL REGISTRATION

The study protocol was registered at clinicaltrials.gov with the following number: NCT05124366 on October 16, 2021.

Desquamative gingivitis: a challenging diagnosis for clinicians

Introduction Diagnosis of underlying causes for desquamative gingivitis (DG) is often delayed in clinical settings, but little is known about factors influencing its delayed diagnosis. We investigated the diagnostic patterns and associated factors in a cohort of patients presenting primarily with DG.Materials and methods A total of 41 patients presenting primarily with DG were interviewed to evaluate professional and patient diagnostic delays. Severity of DG was evaluated using the desquamative gingivitis clinical score (DGCS) proposed by Arduino <i>et al.</i> (2017).Results The study sample was composed of 29 females and 12 males. On average, patients waited 10.8 ± 10 months (range 4-20 months) before seeking their first professional consultation (that is, patient delay). Less severe disease and female gender were significantly associated with longer patient delay. Patients consulted an average of 4.1 ± 2 healthcare professionals (range two to six) before a definitive diagnosis was reached, with an average professional delay of 7.3 ± 5 months (range 2-11 months). Professional delay was positively correlated with the number of professional consultations (r = 0.69) and absence of other oral mucosal lesions or extraoral involvement.Conclusions Considerable diagnostic delay is a feature of the natural history of DG. Increased patient knowledge and professional awareness regarding DG symptoms and diagnostic measures is needed to reduce diagnostic delay and improve patients' experience with this disease.

Investigation of foreign materials in gingival lesions: a clinicopathologic, energy-dispersive microanalysis of the lesions and in vitro confirmation of pro-inflammatory effects of the foreign materials

OBJECTIVES

This study aimed to evaluate the clinical and histopathologic features of gingival lesions containing foreign material (GLFMs). In parallel, the composition of the foreign material and its effects in primary human gingival fibroblasts (HGFs) were investigated.

STUDY DESIGN

Eighty-six GLFMs were retrieved from an oral pathology biopsy service. Clinical and microscopic data were analyzed, and the composition of the particles was identified by using energy-dispersive X-ray spectroscopy (EDX). Furthermore, HGFs were stimulated with silica (SiO₂) microparticles to investigate the production of collagen type 1 (COL-1), matrix metalloproteinase 2 (MMP2), and inflammatory cytokines.

RESULTS

GLFMs were most commonly found in women (60.5%) and most frequently described as white plaques. Histopathologic examination identified verrucous hyperplasia in 59% and epithelial dysplasia in 28% of the cases. EDX microanalysis revealed that Si (94%) was the most frequently detected foreign element. SiO₂ microparticles induced higher COL-1 expression; higher levels of proinflammatory cytokines, such as interleukin-6 (IL-6), IL-8, and transforming growth factor-β, and increased MMP-2 activity in HGFs.

CONCLUSIONS

There was a strong association between the presence of foreign material in the gingiva and white verrucous clinical lesions. In addition, the most common element in the foreign material was Si, and our in vitro findings demonstrate the importance of silica-mediated effects on gingival fibroblasts.

Effects of oral healthcare motivation in patients with gingival oral lichen planus: A randomized controlled trial

OBJECTIVES

The role of dental plaque in gingival lesions caused by oral lichen planus has not been fully defined. The aim of this clinical trial was to evaluate the effects of oral healthcare motivation on clinical variables in patients with gingival oral lichen planus.

MATERIAL AND METHODS

Oral lichen planus patients with symptomatic gingival lesions were randomized in control and intervention groups. The intervention group was instructed to effectively remove bacterial biofilm from dental surfaces, while controls did not receive any advice. The outcome variables were as follows: quality of life (OHIP-14), pain, plaque index and clinical severity of the disease (Escudier index). Outcome variables were assessed at 0, 4 and 20 weeks and analysed using an ANOVA model for factorial design.

RESULTS

Data from 60 patients were collected. Regression analysis showed a significant positive trend of OHIP-14, plaque index and Escudier index in the intervention group compared to controls (p < 0.05). Pain did not prove significantly different (p = 0.408).

CONCLUSIONS

Plaque control improved both OHIP-14 and gingival lesion clinical severity. Oral hygienists should be involved in the multidisciplinary management of patients affected by oral lichen planus with gingival lesions.

Oral hygiene instructions and professional control as part of the treatment of desquamative gingivitis. Systematic review

Background

The aim of this present article was to evaluate the scientific evidence on the efficacy of daily hygiene and professional prophylaxis for treatment of desquamative gingivitis.

Material and Methods

The present systematic review was conducted following the PRISMA protocol. Searches were carried out in Pubmed, Embase, Web of Science and Cochrane Library up to July 2018, randomized clinical trials and cohort studies on desquamative gingivitis (DG), and oral diseases joined to DG.

Results

After screening, we found that nine publications met the eligibility criteria eight cohort studies and one randomized control trial. The diagnosis of the diseases corresponded to oral lichen planus (n=185), mucous membrane pemphigoid (n=13); plasma cell gingivitits (n=15) and pemphigus vulgar (n=11). The follow-up was between a week and a year after instructing patients. Dental daily hygiene and professional prophylaxis, at least with supragingival scaling and polishing have significantly improved the extension of the lesion and reduced the activity of DG, and gingival bleeding in all patients. Furthermore, these techniques have also reduced pain and gingival plaque.

Conclusions

In conclusion the studies presented support the efficacy of maintaining personal and professional oral hygiene in patients with GD, reducing the clinical signs of the disease, regardless of its pathogenesis.

Effect of sonic versus manual supervised toothbrushing on both clinical and biochemical profiles of patients with desquamative gingivitis associated with oral lichen planus: A randomized controlled trial

OBJECTIVES

The aim of this randomized, parallel-design, clinical trial was to investigate the effectiveness of an intensive plaque control programme with sonic versus manual toothbrushing on clinical outcomes and gingival crevicular fluid (GCF) levels of matrix metalloproteinases (MMP) in desquamative gingivitis (DG) patients.

METHODS

A total of 32 patients affected by DG secondary to oral lichen planus (OLP) were consecutively recruited and randomly assigned to a test (n = 16) and control (n = 16) group. Both groups were enrolled in an intensive control programme comprising supragingival scaling and polishing, and brush-specific instructions for a period of 8 weeks. The treatment of interest (test) was the use of a sonic-powered toothbrush, and the standard treatment (control) was the utilization of a soft-bristle manual toothbrush for twice-daily home oral hygiene procedures. Periodontal parameters, patient-centred outcomes, MMP-1 and MMP-9 GCF levels were evaluated at baseline and 8 weeks after starting the programme.

RESULTS

The plaque control programme resulted in statistically significant reduction in periodontal parameters with consequent improvement in the clinical features, painful symptoms and severity of DG lesions in both groups (all P < 0.001). When a sonic toothbrush was used, there was a more significant decrease in clinical indices, mucosal disease scores and GCF levels of MMP-1 and MMP-9.

CONCLUSIONS

This clinical trial reported the effectiveness of a combined protocol based on professional oral hygiene and supervised toothbrushing in OLP patients with DG. The daily use of a sonic toothbrush would seem to perform better in the short term.

Effect of a structured plaque control on MMP-1 and MMP-9 crevicular levels in patients with desquamative gingivitis associated with oral lichen planus

OBJECTIVES

No data are available in the literature on the extent to which the immune host-response and bacterial-elicited inflammation separately contributes to the increase in gingival crevicular fluid (GCF) levels of inflammatory biomarkers in patients affected by desquamative gingivitis (DG) secondary to oral lichen planus (OLP). The aim of this study was to investigate the effect of a structured plaque control intervention on GCF levels of MMP-1 and MMP-9 in OLP patients with DG and to compare them with those of non-OLP patients.

MATERIALS AND METHODS

The study population consisted of 18 unrelated Caucasian patients with DG, while 18 periodontally healthy subjects were recruited for the control group. Periodontal parameters and GCF biomarker amounts were evaluated at baseline and 2 months after a structured plaque control intervention, comprising professional oral hygiene sessions, manual toothbrushing, and interdental cleaning advice, only for DG patients. Determination of MMP-1 and MMP-9 levels was carried out by means of an enzyme-linked immunosorbent assay.

RESULTS

Plaque control program led to improvement in all examined clinical parameters and resulted in significant decrease in GCF total amount and concentration of MMP-1 and MMP-9 in comparison to baseline (p < 0.001). However, MMP-1 and MMP-9 levels in DG patients were still significantly higher than those in the healthy control group (p < 0.01).

CONCLUSIONS

These findings would seem to support an intrinsic upregulated expression of MMPs in DG patients that is exacerbated by bacterial plaque.

CLINICAL RELEVANCE

The present outcomes provide further scientific grounds for the importance of strict professional oral hygiene sessions in DG patients.
