[A woman with gingival enlargement]. / Een vrouw met gezwollen tandvlees.

A 65-year-old female complained of diffuse and rapidly progressive gingival enlargement. Gingival overgrowth can be caused by medication, infections or systemic diseases. In case of generalized, quickly progressive gingival enlargement, acute myeloid leukemia should be considered. Blood results showed an acute myelomonocytic leukemia. Treating the leukemia resolved the symptoms.

Treatment of calcium channel blocker-induced gingival overgrowth without modifying medication.

Gingival overgrowth is a common side effect of calcium channel blockers used in the treatment of cardiovascular diseases. While controversial, management includes discontinuing the calcium channel blocker. We report the case of a 66-year-old Japanese man with hypertension and type 2 diabetes mellitus who was diagnosed with severe periodontitis covering almost all the teeth. The patient had been on nifedipine (40 mg/day) and amlodipine (10 mg/day) medication for 5 years. With his physician's consent, nifedipine was discontinued during his treatment for periodontitis, which consisted of oral hygiene instructions and scaling and root planing on all areas. Gingivectomy was performed on the areas of hard fibrous swelling. Nifedipine was resumed during periodontal treatment when the patient's hypertension worsened. His periodontal scores improved when he resumed treatment. We report that significant improvement in gingival overgrowth can occur with basic periodontal treatment, surgery and sustained intensive follow-up without adjusting calcium channel blockers.

Amlodipine-induced gingival enlargement: A case report.

Gingival enlargements (GEs) can be caused by local, systemic diseases or drugs. Three molecules can be responsible of GEs: ciclosporin, phenytoin and calcium channel blockers (CCBs). We report the case of a 56-year-old male treated by Amlodipine, a CCB, for hypertension for many years and who recently developed a severe GE affecting both mandibular and maxillary arches inducing dental malposition. The histological examination showed non-specific inflammation with a predominance of lymphocytes. Amlodipine was suspected and suspended in agreement with his physician. One month later, the enlargement significantly reduced but GE was so severe and dental malposition so marked that all the teeth but the canines were extracted. No recurrence was noted one year later. This exceptional case should encourage every practitioner to be vigilant with patient treated with CCBs and their potential side effects and consequences.

Tuberous Sclerosis Complex with Gingival Enlargement in an Adolescent.

Tuberous sclerosis complex (TSC) is an autosomal dominant, multisystem genetic disorder. It is characterised by formation of benign hamartomas, neurofibromas, and angiofibromas located in different organs. We describe a case of a 13-year boy who complained of gingival enlargement. Clinical examination showed distinctive dermatological signs like hypopigmented macules, shagreen plaques, miliary fibromas, fibrous plaques and multiple angiofibromas. Oral manifestation included localised gingival enlargement. Gingivectomy was performed and the excised tissue was submitted for histopathological examination. The microscopic examination of gingival tissue revealed multiple bundles of collagen fibres with proliferating fibroblast and multiple proliferating blood vessels in the connective tissue. The clinical and histopathological findings were consistent with gingival angiofibromas of TSC. Gingivectomy allowed the patient to have better function and aesthetics. Periodontal examination in conjunction with dermatological examination is important for early diagnosis of TSC.

Oral health of pediatric liver transplant recipients.

To evaluate oral health conditions in pediatric liver transplant recipients, with special focus on caries, green staining of the teeth, gingival bleeding, and gingival overgrowth. 40 patients (mean age 11.6 years) were examined at a routine follow-up visit, 6 months to 16 years after liver transplantation at the Swiss Center for Liver Disease in Children. After the medical examination, participants were further examined for the presence of dental caries, periodontal disease, GE, and GTC. The mean decay, missing, and filled teeth (dmft/DMFT) score was 3.8. 45% of the participants presented at least one carious lesion. Two-third of the participants had more than 20% of sites with the presence of plaque and gingival inflammation. Signs of GE were found in 18% and GTC in 30% of the participants. A positive correlation was identified between GTC and peak serum bilirubin (P<.001) and primary diagnosis of cholestatic disease (P=.04). Gingival inflammation was associated with plaque (P<.001), use of immunosuppressive medication (P=.04), and was more pronounced in children with cholestatic disease (P=.007). Children and young adults with liver transplants presented a rather poor oral health status. Liver transplant physicians should counsel patients for regular dental follow-up in order to avoid serious dental infections.

Gingival overgrowth: Part 2: management strategies.

The effective and predictable management of gingival overgrowth requires correct diagnosis and consideration of aetiological factors, as discussed in Part 1 (BDJ 2017; 222: 85-91). Initial management should involve cause-related therapy, which may resolve or reduce the lesion. If functional, aesthetic and maintenance complications persist following this phase; further treatment may be required in the form of surgery. This paper discusses management strategies, including management of aetiological factors and surgical techniques.

Gingival overgrowth: Part 1: aetiology and clinical diagnosis.

Most commonly, gingival overgrowth is a plaque-induced inflammatory process, which can be modified by systemic disease or medications. However, rare genetic conditions can result in gingival overgrowth with non-plaque-induced aetiology. It is also important to appreciate the potential differential diagnoses of other presentations of enlarged gingival tissues; some may be secondary to localised trauma or non-plaque-induced inflammation and, albeit rarely, others may be manifestations of more sinister diseases or lesions. A definitive diagnosis will then enable an appropriate management strategy. This paper aims to discuss clinical features and diagnoses for conditions presenting with gingival overgrowth and other enlargements of gingival tissues.

Using Salivary Nitrite and Nitrate Levels as a Biomarker for Drug-Induced Gingival Overgrowth.

AIM: Drug-induced gingival overgrowth has a multifactorial nature and the pathogenesis is still uncertain. It has been suggested that Nitric Oxide (NO) might play a role in the pathogenesis of drug-induced gingival overgrowth due to the contribution of NO to immune response and matrix degradation. NO levels in biological fluids have been used as a diagnostic biomarker in many diseases. The aim of this study is to determine whether NO levels in plasma, saliva, and gingival crevicular fluid (GCF) can serve as a potential biomarker for the evaluation of drug-induced gingival overgrowth risk. MATERIALS AND METHODS: A total of 104 patients, receiving cyclosporine A (n = 35), phenytoin (n = 25), nifedipine (n = 26), or diltiazem (n = 18) participated in the study. The amount of gingival overgrowth was evaluated with two indices and was given as percentage. Periodontal clinical parameters including plaque index (PI), gingival index (GI), gingival bleeding time index (GBTI), and probing depth (PD) were also assessed. Saliva, GCF, and plasma samples were obtained from each participants. Nitrite and nitrate levels in saliva, GCF, and plasma were analyzed by Griess reagent. RESULTS: Salivary nitrite and nitrate levels in responders were significantly higher than those in non-responders in only phenytoin group (p < 0.05). Nitrite and nitrate levels of gingival crevicular fluid and plasma did not significantly differ between responders and non-responders in all study groups (p > 0.05). Salivary nitrite levels exhibited a significant correlation with PD, GBTI, severity of gingival overgrowth (%GO), and GCF volume (p < 0.05). Additionally, a strong positive correlation was detected between saliva and plasma nitrate levels (p < 0.005). However, both nitrite and nitrate levels in GCF and plasma demonstrated no significant correlation with clinical parameters, GO severity, and GCF volume (p > 0.05). CONCLUSION: Salivary nitrite and nitrate levels could be used as periodontal disease biomarkers in phenytoin induced gingival overgrowth, and that saliva seems to have a better diagnostic potential than GCF and plasma for the evaluation of drug-induced gingival overgrowth risk. However, when all drug groups were considered, saliva nitrite and nitrate levels could not be used as a biomarker for drug-induced gingival overgrowth.

Oral manifestations of neurofibromatosis type 1 in children with facial plexiform neurofibroma: report of three cases.

Neurofibromatosis type 1 (NF1) is a common autosomal genetic disorder with a prevalence of 1 in 3,000 births. NF1 is a complex syndrome characterized by many abnormalities and may affect all organ systems. Oral manifestations of NF1 occur frequently, but reports including NF1 children with facial plexiform neurofibromas and oral alterations are scant. Facial plexiform neurofibroma may cause asymmetry, disfigurement and usually arises from the trigeminal nerve. The aim of this paper is to to report three pediatric NF1 cases with facial plexiform neurofibroma presenting with oral manifestations, which were evaluated clinically and radiographically, and also to briefly review the literature. Patients presented with changes in the oral soft tissues, jaws, and teeth ipsilateral to the tumor.

Diagnosis and management of focal reactive overgrowths of gingiva--a case series.

Localized overgrowths of gingiva such as peripheral fibroma, peripheral ossifying/cementifying fibroma, pyogenic granuloma and peripheral giant cell granuloma belong to a common group of lesions designated as focal reactive overgrowths (FROG). These growths are reactive in nature. They occur in response to chronic, low grade irritation caused by plaque or any other irritant. Etiology, clinical features and treatment modes of these lesions are the same with slight variations. The present case series describes five different cases of FROG where the lesions were treated by surgical excision under local anesthesia followed by a three month re-evaluation where no recurrences were observed.

Phenytoin-induced severe gingival overgrowth in a child.

Gingival enlargement or overgrowth (GO) is a common complication of the anticonvulsant drug phenytoin (PHT). GO is evident in almost half of the patients receiving PHT therapy. PHT-induced gingival overgrowth (PGO) is more common in children than in adults and affects both males and females equally. PGO may vary from mild to severe and does not seem to be dose dependant. It is supposed that PHT and its metabolites cause a direct effect on the periodontal tissues; however, poor oral hygiene may contribute to the severity of gingival inflammation in patients with PGO. Management of PGO includes meticulous oral hygiene practice to reduce inflammation and surgical excision of the overgrown tissue, known as gingivectomy. We present a case of PHT-induced severe GO in a 10-year-old boy and discuss the clinical features, aetiology, pathogenesis and management of PGO.

Nephrocalcinosis associated with continuous enamel hypoplasia and severe alveolar bone loss: a case report and literature review.

Enamel-renal syndrome (ERS) is a rare manifestation of nephrocalcinosis that has been associated with generalized enamel hypoplasia. The purpose of this paper was to describe, for the first time, the association of enamel-renal syndrome with severe localized periodontal bone loss. A 13-year-old boy presented with: generalized hypoplastic enamel; intrapulpal calcifications; retention of primary teeth; delayed eruption of permanent teeth; enlarged dental-follicles; misshaped roots of permanent teeth; gingival overgrowth; severe localized alveolar bone loss; and severe malocclusion. His parents were first cousins, suggesting autosomal recessive inheritance. Further studies are necessary to clarify whether the etiology of the oral disturbances relates to the genetic defect in the dental tissue or to the continuous metabolic distress associated with renal dysfunction. Nevertheless, since nephrocalcinosis is often asymptomatic, dentists should refer children with generalized enamel hypoplasia or/and multiple intrapulpal calcifications to nephrologists.

Rare occurrence of lobular capillary hemangioma on the palate: possible mechanism and treatment considerations.

Lack of striking clinical presentation makes the diagnosis of vascular lesions a difficult task. There lies a great probability that a case of capillary hemangioma at a rare location like the palate in a pregnant female might be misdiagnosed. Definitive diagnosis can only be made after thorough clinical and histopathological examination. Additional care needs to be exercised in a pregnant female while treating any tumor-like growth, including maintenance of diet and oral hygiene. We present one such case of capillary hemangioma of the palate in a pregnant female, along with treatment considerations.

Thus, the conduct based on accurate anamnesis, clinical evaluation and careful observation of the patient during pregnancy is crucial to the achievement of the treatment, which can be surgical or just observational. It is important to highlight the need for care with hygiene, plaque removal and proper use of toothbrushes with brushing techniques that reduce the trauma of the oral mucosa...

Gingival overgrowth in renal transplant subjects: a 44-month follow-up study.

BACKGROUND: To assess changes in gingival status of renal transplant subjects under immunosuppressive regimens based on cyclosporine (CsA), tacrolimus (Tcr), and sirolimus (Sir). METHODS: From a sample of 135 subjects (baseline examination [BE]), 89 without periodontal treatment, who maintained the immunosuppressive regimen based on the same main agent (CsA=23, Tcr=31, and Sir=35), were reexamined after 44 months (follow-up examination [FE]). Demographic, pharmacologic, and periodontal variables were collected and gingival overgrowth (GO) was assessed by visual examination. RESULTS: In Tcr and CsA groups, although not significant, occurrence of GO decreased (CsA [BE=56.5% and FE=34.8%; P=0.063] and Tcr [BE=19.4% and FE=12.9%; P=0.500]). In addition, the severity of GO decreased significantly in CsA group (mean score BE=10.29 ± 7.70 and mean score FE=0.78 ± 1.38; P=0.003). In Sir group, GO decreased from 17.1% (BE) to 0.0% (FE) (P=not applicable). In total sample, GO was associated with papillary bleeding index (P=0.001) and concomitant use of calcium channel blockers (P=0.029); in CsA and Tcr groups, GO was associated with papillary bleeding index (P=0.029 and 0.033, respectively). CONCLUSIONS: There was no incidence of GO, and a decrease in the occurrence and severity of GO was significant in total sample. This decrease can be attributed to changes in pharmacologic and periodontal variables over this period of time.

Non-drug induced gingival enlargement.

Gingival enlargement refers to an increase in the size of the gingival tissue. The etiology varies, and often is multifactorial; however, local and systemic conditions, disease, and idiopathic factors may contribute to gingival enlargement. Tissue consistency can vary from soft and spongy to dense, typically appearing darker in shade compared to the drug-induced gingival enlargement. Treatment modalities usually involve surgical removal of excess tissue, non-surgical debridement, use of chemotherapeutic agents, and/or elimination or mitigation of contributing factors and conditions.
