Diffuse gingival enlargement

Non-Plaque Induced Diffuse Gingival Overgrowth: An Overview

Non-plaque induced diffuse gingival overgrowth represents a broad class of conditions caused by several etiological factors. The aim of this review is to highlight the most recent updates and classifications of all the existent gingival overgrowths. In addition, we highlighted the diagnostic pathway that should be employed in patients affected by gingival overgrowth. Gingival overgrowth can be related to syndromic diseases including a wide spectrum of genetic and chromosomal alterations. However, thanks to scientific sharing and the availability of genetic panels it is possible to obtain an accurate phenotypic identification of well-known syndromes and also to identify new ones. This narrative review shows that through rigid, strict diagnostic protocols, the work of the clinician is greatly facilitated, despite the wide variety of pathologies considered. In conclusion, the exchange of specialists’ competencies and the multidisciplinary management of these patients, are crucial to reach diagnosis and the correct clinical-therapeutic management.

Evaluation of Therapeutic Benefits of a Novel Herbal Ingredient-Based Hyaluronic Acid Gel as Monotherapy for Inflammatory Enlargement of a Patient with Diabetes Mellitus

The reason for the destruction of the attachment apparatus in patients with periodontal disease is the supra- and the subgingival microflora. Hence, the treatment of this inflammatory gingival disease is primarily focused on eliminating the cause. The present case report assessed the therapeutic benefit of adjunctive use of a commercially available topical agent containing 1% hyaluronic acid gel combined with nonsurgical periodontal therapy. A patient aged 64 years with type 2 diabetes mellitus reported to the Department of Periodontology. He complained of gum enlargement and frequent bleeding during brushing. The patient was not under any medication for his diabetes control. On examination, there was a localized papillary gingival enlargement. Therefore, Klirich gel containing hyaluronic acid was applied on the surface of the gingiva during the first visit of the patient. During the follow-up visit, he continued with this adjunctive use of the gel along with the nonsurgical periodontal therapy. In addition, he controlled his blood sugar level with diet and exercise. During the follow-up visit after one year, there was a noticeable clinical change in the overall health of his gingiva.

REST Final-Exon-Truncating Mutations Cause Hereditary Gingival Fibromatosis

Hereditary gingival fibromatosis (HGF) is the most common genetic form of gingival fibromatosis that develops as a slowly progressive, benign, localized or generalized enlargement of keratinized gingiva. HGF is a genetically heterogeneous disorder and can be transmitted either as an autosomal-dominant or autosomal-recessive trait or appear sporadically. To date, four loci (2p22.1, 2p23.3-p22.3, 5q13-q22, and 11p15) have been mapped to autosomes and one gene (SOS1) has been associated with the HGF trait observed to segregate in a dominant inheritance pattern. Here we report 11 individuals with HGF from three unrelated families. Whole-exome sequencing (WES) revealed three different truncating mutations including two frameshifts and one nonsense variant in RE1-silencing transcription factor (REST) in the probands from all families and further genetic and genomic analyses confirmed the WES-identified findings. REST is a transcriptional repressor that is expressed throughout the body; it has different roles in different cellular contexts, such as oncogenic and tumor-suppressor functions and hematopoietic and cardiac differentiation. Here we show the consequences of germline final-exon-truncating mutations in REST for organismal development and the association with the HGF phenotype.

[Inflammatory diseases of oral mucous membranes]

BACKGROUND

Mucous membranes are involved in many different inflammatory disorders.

METHODS

We describe the clinical features, diagnostic workup, and therapy of inflammatory diseases of mucous membranes.

RESULTS

The diagnostic workup is based on medical history, clinical manifestations, histopathology, and serology. Inadequate dental hygiene is one of the main pathogenetic factors. Treatment options depend on the diagnosis, underlying cause, and disease severity. Both local and systemic immunosuppressive or immunomodulatory strategies may be effective.

CONCLUSIONS

The diagnostic and therapeutic management of inflammatory mucous membrane disorders is usually more difficult than that of skin diseases and requires interdisciplinary cooperation.

Destructive membranous periodontal disease (ligneous gingivitis): a literature review

BACKGROUND

Destructive membranous periodontal disease, or ligneous gingivitis, is a rare condition involving nodular gingival enlargement with ulceration and periodontal tissue destruction. This review gives a brief account of the cases reported in the literature. An effort is also made to define the periodontal disease caused by plasminogen deficiency with a view to its potential inclusion in the classification of periodontal diseases.

METHODS

A MEDLINE/PubMed and manual search was conducted to find papers describing ≥1 case of ligneous disease involving the oral mucosa.

RESULTS

We identified 23 articles reporting 35 cases. For each patient, we analyzed various characteristics, including age, sex, age of onset, oral symptoms, histologic features, plasminogen levels (functional activity, plasma antigen), genetic features, treatment, and results of treatment during the reported follow-up.

CONCLUSIONS

Ligneous gingivitis is a rare periodontal disorder closely associated with ligneous conjunctivitis and plasminogen deficiency. Its diagnosis may be supported by the finding of genetic mutations responsible for the condition. Research is focusing on the future development of an effective therapy capable of arresting the destructive evolution of the disease. Additional studies, investigating features such as probing depth and attachment loss, are needed for the appropriate classification of this periodontal disease.

Lip and oral mucosal lesions in 100 renal transplant recipients

BACKGROUND

Renal transplant recipients (RTRs) appear to be more susceptible to the development of oral mucosal disease and lip cancer as a result of graft-preserving immunosuppressive therapy. However, reports regarding these pathologies other than lip cancer are scarce and not studied in a detailed manner in this patient population.

OBJECTIVE

The aim of this study was to determine the prevalence rates and clinical features of lip lesions and oral mucosal lesions (OMLs) in RTRs.

METHODS

In all, 100 consecutive RTRs (21 female and 79 male) and 79 healthy age- and sex-matched control subjects (23 female and 56 male) were screened for all pathologic and pseudopathologic lip lesions and OMLs, with special interest on precancerous and cancerous lesions. Information about possible associated risk factors such as smoking and alcohol consumption was also obtained. Dermatologic investigation included clinical observation and direct microscopic examination, culture, and histopathological evaluation when indicated.

RESULTS

One or more lip lesions, OMLs, or both were noted in every participant of both groups. Fordyce spots on the lips was the most common lesion in the patient group (73%), followed by diffuse gingival enlargement (39%), fissured tongue (35%), and oral candidiasis (26%). The last 3 disorders were significantly more common in RTRs, whereas the frequency of Fordyce spots in patients and control subjects was similar. No actinic cheilitis, lip cancer, or oral malignancy was observed.

LIMITATIONS

This was a relatively small sample size for evaluating precancerous and cancerous lip lesions and OMLs, as they are less frequently observed than benign lesions.

CONCLUSIONS

Some of the benign OMLs (oral candidiasis and diffuse gingival enlargement) are increased in RTRs mainly as a result of the immunosuppressive therapy or drug side effects. Precancerous or cancerous lesions were not observed on the lips or the oral mucosa of our RTRs. This finding is in direct contrast with those of previous studies, yet this can be related to the limited sample size of this study regarding these lesions.

Scurvy in a patient with depression

Scurvy is a nearly-forgotten disease in developed countries where adequate nutrition is easily available. It still may occur, however, when, for a variety of reasons, people fail to eat a diet containing adequate vitamin C. We report the case of a 52-year-old patient with depression who developed scurvy.
