Abstract
Abstract
Calcium channel blockers, a group of drugs widely used in the treatment of cardiovascular patients, although effective, often cause gingival enlargement, a side effect that is rarely recognized in clinical practice and is not given sufficient importance. Gingival enlargement caused by calcium channel blockers can be localized or generalized, mild or severe. It can negatively affect patients’ appearance, mastication, and speech, thus considerably reducing the quality of life of patients. Risk factors and pathogenesis of this side effect have been the subject of many studies but are still unknown, making this condition a major therapeutic challenge, especially if the cessation of the offending drug is not possible. This study aimed to review the etiology, potential risk factors, pathogenesis, clinical features, and therapy possibilities for gingival enlargement caused by calcium channel blockers.

Impact of Immunosuppressive Drugs on Fibroblasts: An In Vitro Study. J Clin Med 2022; 11:jcm11113107. [PMID: 35683494 PMCID: PMC9181118 DOI: 10.3390/jcm11113107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 05/17/2022] [Accepted: 05/24/2022] [Indexed: 12/04/2022] Open
Abstract
Background: The aim of this study was to compare the direct impact of different agents for immunosuppressive therapy on mouse fibroblasts as a possible cause of drug-induced gingival overgrowth (DIGO). Methods: 3T3 mouse fibroblasts were cultivated in cell-specific media (2 × 104 cells/mL) and treated for 6, 24, 48 and 72 h with one of three immunosuppressive drugs (IsDs): cyclosporin a (CsA), tacrolimus (TaC) and sirolimus (SiR). Different concentrations (10−750 ng/mL) were used to mimic serum levels under active immunosuppressive therapy conditions. Cell population characteristics (cell number, viability and morphology) were assessed using computer-assisted cell analysis. Expression of pro-collagen type I carboxy-terminal propeptide (PICP) was identified using an ELISA assay. Results: The influence of IsDs on the biological status of 3T3 fibroblasts was time- and dose-dependent. Comparing CsA and TaC, the total cell amount was enhanced using concentrations in the range of 10−150 ng/mL (p > 0.05). In contrast, treatment with SiR resulted in a decrease in the average cell number (p < 0.01). PICP and cell diameter of fibroblasts were not susceptible to IsD treatment (p > 0.05). Conclusions: Our results revealed time-dependent effects of IsDs, with distinct influences on cell number. The cell morphology and the PICP balance of the investigated fibroblast cell line remained unaffected. Hence, the potential role of IsDs is not a unilateral mechanism of action but rather a multifactorial process.

Abstract
Drug-influenced gingival enlargement (DIGE) or overgrowth manifests as abnormal enlargement of the gingiva due to an adverse effect of certain drug reactions in patients treated with anticonvulsants, immunosuppressants, or calcium channel blockers (CCBs). As the gingival enlargement became significant, it may interfere with the normal oral hygiene measures, aesthetics, as well as masticatory functions of the patients. The exact mechanism of how this undesirable condition develops is yet unknown, and complicated, with non-inflammatory and inflammatory pathways involved. This review illuminates these putative pathways of DIGE and highlights various treatment approaches based on existing research and current observations.

Abstract
Drug-induced gingival overgrowth (DIGO) is a pathological growth of gingival tissue, primarily associated with calcium channel blockers and immunosuppressants. Consequently, it is mainly seen in cardiovascular and transplanted patients. Nifedipine remains the main calcium channel blocker related to the development of this unpleasant side-effect. As for immunosuppressants, cyclosporin is the leading causative agent, whereas other drugs from this drug-group, including tacrolimus, have better safety profiles. Accumulated collagen with inflammatory infiltrates is the histological hallmark of this condition. Several factors are involved in the pathogenesis and can increase the risk, such as male gender, younger age, pre-existing periodontal inflammation, and concomitant use of other DIGO-inducing medications. Patients with DIGO may experience severe discomfort, trouble with speech and mastication, pain, and teeth loss, aside from cosmetic implications. Furthermore, these patients also have an increased risk for cardiovascular diseases. The interdisciplinary approach and cooperation with dental care experts are necessary for patient management. Treatment includes discontinuing the drug and switching to one with a better profile, improving oral hygiene, and surgical removal of enlarged tissue. Recognizing the potential of commonly used medications to cause DIGO and its effect on patients' health is necessary for early detection and adequate management of this complication.

Abstract
Aging is characterized by a progressive decline or loss of physiological functions, leading to increased susceptibility to disease or death. Several aging hallmarks, including genomic instability, cellular senescence, and mitochondrial dysfunction, have been suggested, which often lead to the numerous aging disorders. The periodontium, a complex structure surrounding and supporting the teeth, is composed of the gingiva, periodontal ligament, cementum, and alveolar bone. Supportive and protective roles of the periodontium are very critical to sustain life, but the periodontium undergoes morphological and physiological changes with age. In this review, we summarize the current knowledge of molecular and cellular physiological changes in the periodontium, by focusing on soft tissues including gingiva and periodontal ligament.

Abstract
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.

Abstract
AIM The aim of this study was to evaluate whether there is a relationship between gender and oral health status of children with autism spectrum disorders (CASD). MATERIAL-METHODS The study was carried out with 348 children. The children were separated into two groups to evaluate the prevalence of caries and to assess oral disorders in terms of gender. The following factors were evaluated: mean dmft (decayed missed filled permanent tooth in primary dentition), mean DMFT (decayed missed filled permanent tooth in permanent dentition), plaque index, caries prevalence scores, dental crowding, open bite, deep palate, drooling of saliva, tongue thrusting habit, bruxism, dental and soft tissue trauma, tooth wear, delayed eruption, and hypodontia. RESULTS The results showed that the mean dmft in boys with CASD (BCASD) was lower than the mean dmft in healthy boys. The mean dmft of the girls with CASD (GCASD) was also lower than that of the healthy girls. The prevalence of dental caries and mean DMFT in GCASD were higher than those of BCASD in permanent dentition. While the plaque index value of BCASD was higher than that of healthy boys, the plaque index value of GCASD was lower than that of healthy girls. The plaque index value of BCASD was higher than that of GCASD. GCASD were reported to have significantly more bruxism than their healthy counterparts. However, no statistically significant difference was found between BCASD and healthy boys regarding bruxism. Moreover, there was no significant difference between BCASD and GCASD in terms of bruxism. Drooling of saliva in BCASD was less than GCASD. CONCLUSION There were significant gender differences between CASD and healthy children in terms of dental caries and oral disorders in this study. There were also significant differences regarding dental caries and oral disorders between GCASD and BCASD.

Abstract
We evaluated the effect of cyclosporine A (CsA) administration on the level of miR-26-5p in rat gingival tissues and human gingival fibroblasts (HGFs) by qRT-PCR assay. Further, we conducted Western blotting and immunohistochemical analysis to assess the expressions of PTEN, PI3K, and p-AKT, and evaluated cell proliferation of HGFs by MTT assay. CsA treatment significantly downregulated the expressions of miR-26-5p and PTEN and upregulated the expressions of PI3K and p-AKT in both rat gingival tissues and HGFs. Overexpression of miR-26-5p inhibited CsA-induced overgrowth of HGFs, whereas knockdown of miR-26-5p promoted the overgrowth. PTEN knockdown not only promoted CsA-induced overgrowth of human HGFs but also reversed the repressive effects of miR-26-5p on CsA-induced overgrowth of HGFs. Our results revealed that miRNA-26-5p could repress CsA-induced overgrowth of human HGFs by regulating PTEN/PI3K/AKT pathway.

Abstract
Background Gingival tissue enlargement is a common side effect of antiepileptic medications (e.g. phenytoin and sodium valproate), immunosuppressing drugs (e.g. cyclosporine) and calcium channel blockers (e.g. nifedipine, verapamil, amlodipine) (Murakami et al. 2018, Clin Periodontol 45:S17–S27, 2018). The clinical and histological appearances of lesions caused by these drugs are indistinguishable from one another (Murakami et al. 2018, Clin Periodontol 45:S17–S27, 2018). Drug-induced gingival enlargement is rarely seen in edentulous patients. Case presentation This case presents a 72-year-old female with a history of squamous cell carcinoma of the floor of the mouth treated with surgical excision and fibula-free flap reconstruction. Following the uncovering of osseointegrated implants placed in the fibular-free flap, the patient developed gingival enlargement of the floor of the mouth. Cessation of amlodipine and switching to an alternative medication lead to a resolution of the enlarged tissue. Conclusions This case illustrates that gingival enlargement can occur around dental implants, most notably in rehabilitation cases in patients who have had head and neck cancer. Clinicians should be aware of the risk of gingival enlargement in hypertensive patients taking calcium channel blockers prior to implant placement.

Abstract
Gingival overgrowth is a serious side effect that accompanies the use of amlodipine. Several conflicting theories have been proposed to explain the fibroblast’s function in gingival overgrowth. To determine whether amlodipine alters the inflammatory responses, we investigated its effects on gingival fibroblast gene expression as compared with untreated cells. Fragments of gingival tissue of healthy volunteers (11 years old boy, 68 years old woman, and 20 years old men) were collected during operation. Gene expression of 29 genes was investigated in gingival fibroblast cell culture treated with amlodipine, compared with untreated cells. Among the studied genes, only 15 (CCL1, CCL2D, CCL5, CCL8, CXCL5, CXCL10, CCR1, CCR10, IL1A, IL1B, IL5, IL7, IL8, SPP1, and TNFSF10) were significantly deregulated. In particular, the most evident overexpressed genes in treated cells were CCR10 and IL1A. These results seem to indicate a possible role of amlodipine in the inflammatory response of treated human gingival fibroblasts.

Abstract
BACKGROUND AND OBJECTIVES Amlodipine, a calcium channel blocker derivative, is frequently used by patients with high blood pressure. Studies reported that it can induce gingival overgrowth. However, the underlying mechanism is not fully described yet. Interleukin-17A (IL-17A) is known as a proinflammatory cytokine, but current studies indicate that it has a role in fibrotic disorders and epithelial-mesenchymal transition (EMT). The aim of this study was to figure out the possible role of IL-17A in amlodipine-induced gingival overgrowth. MATERIALS AND METHODS Twenty-nine (29) individuals participated in the study, and they were assigned into 3 groups based on medical status and clinical periodontal examination; 9 patients with amlodipine-induced gingival overgrowth, 11 patients with inflammatory gingival overgrowth, and 9 healthy individuals as a control group. Clinical periodontal parameters including plaque index (PI), gingival index (GI), and gingival overgrowth index (GOI) were recorded. Blood and gingival crevicular fluid (GCF) samples were obtained. Gingival tissues were taken by appropriate periodontal surgery following initial periodontal therapy. To detect IL-17A on tissue samples, immunohistochemistry (IHC) was performed. Quantitative analysis was done, and the expression level of IL-17A was given as the percent positively stained cells. Enzyme-linked immunosorbent assay (ELISA) kits were used to analyze IL-17A in serum and GCF samples. RESULTS All recorded clinical parameters were significantly higher in gingival overgrowth groups compared with control. Evaluation of inflammation on tissue sections did not show any significant change within the groups. Immunohistochemistry findings showed that IL-17A expression was increased in amlodipine samples (81.90%) compared with control samples (42.35%) (P < .001). There was an increase in the inflammatory group (66.08%) which is significantly less than the amlodipine group (P < .05). IL-17A levels in serum and GCF samples were not different within the study groups. CONCLUSION In this study, elevated IL-17A expression regardless of inflammation shows that amlodipine might cause an increase of IL-17A in gingival tissues. This increase might induce fibrotic changes and EMT in gingival overgrowth tissues. The association of IL-17A with fibrosis and EMT in gingival tissues requires further investigation.

Abstract
Objectives: To prove the role of epithelial mesenchymal transition (EMT) in the pathogenesis of phenytoin influenced gingival overgrowth (PIGO) in children and young adults. Study design: Thirty male individuals who are to start with oral phenytoin therapy were recruited for the study. All the 30 individuals underwent full mouth scaling and root planning and were then followed up for a period of one year at intervals of 3 months each. Based on the clinical gingival status they were divided into group1 (responders) individuals who showed gingival overgrowth (GO) and group 2 (non responders) individuals who do not show any GO. Gingival tissue samples were obtained from both the groups at the end of 1 year and subjected to immuno histochemical analysis for E-cadherin expression and histo-pathological for alteration in the basement membrane and confirmation of the fibrosis. Results: Decrease in expression of E cadherin, loss of basement membrane integrity and fibrosis were noted on responder group when compared to non responder group at p<0.001. Fibrosis was seen in the epithelial connective tissue junction. Conclusion: Decrease in cell adhesion, degradation of basement membrane and presence of fibrosis could suggest the role of EMT in the pathogenesis of PIGO.

Abstract
Immune suppressed renal transplant patients are more prone to developing oral tissue alterations due to medications associated with a pleiotropic set of side effects involving the oral cavity. Drug-induced gingival overgrowth (DIGO) is the most commonly encountered side effect resulting from administration of calcineurin inhibitors such as cyclosporine-A (CsA), the standard first-line treatment for graft rejection prevention in transplant patients. Pathogenesis of gingival overgrowth (GO) is determined by the interrelation between medications and a pre-existing inflammatory periodontal condition, the main modifiable risk factor. Severity of gingival hyperplasia clinical manifestation is also related to calcium channel blocker association, frequently provided in addition to pharmacological therapy of transplant recipients. Specifically, nifedipine-induced enlargements have a higher prevalence rate compared to amlodipine-induced enlargements; 47.8% and 3.3% respectively. Available epidemiological data show a gender difference in prevalence, whereby males are generally more frequently affected than females. The impact of GO on the well-being of an individual is significant, often leading to complications related to masticatory function and phonation, a side effect that may necessitate switching to the tacrolimus drug that, under a similar regimen, is associated with a low incidence of gingival lesion. Early detection and management of GO is imperative to allow patients to continue life-prolonging therapy with minimal morbidity. The purpose of this study was threefold: firstly, to determine the prevalence and incidence of GO under the administration of CsA and Tacrolimus; secondly, to assess the correlation between periodontal status before and after periodontal therapy and medications on progression or recurrence of DIGO; and finally, to analyse the effect of immunosuppressant in association to the channel blocker agents on the onset and progression of gingival enlargement. We compared seventy-two renal transplant patients, including 33 patients who were receiving CsA, of which 25% were also receiving nifedipine and 9.72% also receiving amlodipine, and 39 patients who were receiving tacrolimus, of which 37.5% were also receiving nifedipine and 5.55% also receiving amlodipine, aged between 35 and 60 years. Medical and pharmacological data were recorded for all patients. Clinical periodontal examination, in order to establish the inflammatory status and degree of gingival enlargement, was performed at baseline (T0), 3 months (T1), 6 months (T2), and 9 months (T3). All patients were subjected to periodontal treatment. Statistically significant correlation between the reduction of the mean value of periodontal indices and degree of gingival hyperplasia at the three times was revealed. The prevalence of GO in patients taking cyclosporine was higher (33.3%) in comparison with those taking tacrolimus (14.7%). In accordance with previous studies, this trial highlighted the clinical significance of the pathological substrate on stimulating drug-induced gingival lesion, confirming the key role of periodontal inflammation in pathogenesis of gingival enlargement, but did not confirm the additional effect of calcium-channel blocker drugs in inducing gingival enlargement.

Abstract
Background:Previous studies have shown possible association between periodontal diseases and Diabetes Mellitus (DM), Cardiovascular Disease (CVD) and Adverse Pregnancy Outcomes (APO). Increasing the knowledge of physicians and dentists regarding the association between periodontal disease and systemic diseases should improve their ability to provide a high standard of treatment for the disease and prevent its consequences. In our study, we sought to identify knowledge gaps in the awareness of the relationship between systemic and periodontal diseases among dentists and physicians from the Kingdom of Saudi Arabia and the State of Kuwait.Methods:A cross-sectional study was performed with a convenient sample of selected physicians and dentists in Saudi Arabia and Kuwait using a self-developed structured questionnaire. Physicians’ and dentists’ awareness were assessed regarding current evidence of the relationship between systemic diseases and conditions (DM, CVD, APO) and periodontal diseases.Results:A total of 134 (21.5%) of the identified physicians and 485 (78%) of the identified dentists participated in this study. More than half of the participants (52.1% physicians and 67.5% dentists) agreed that there is a relationship between periodontal diseases and DM, CVD and APO. Dentists had a statistically higher level of awareness compared with the physicians. The findings related to the awareness of the dentist sub groups highlighted that periodontists were significantly more likely to have a good level of knowledge.Conclusion:Within the limitations of this study, we concluded that the awareness of physicians and dentists regarding the relationship between periodontal diseases and systemic diseases (DM, CVD, APO) is generally low, Therefore, improved collaboration between medical and dental health providers is recommended.

Abstract
Drug-induced gingival overgrowth is a condition caused by side effects of treatment with one of three types of drugs: phenytoin (used in epilepsy treatment), cyclosporine A (used in transplantology after allogenic organ transplants) and calcium channel blockers (used in the treatment of hypertension). Gingival overgrowth leads to inflammation within the gums and periodontium and can amplify the existing periodontal disease leading to tooth loss. Patients who have undergone kidney transplant are given immunosuppressants to prevent transplant rejection and mostly it is accompanied with calcium channel blockers to treat hypertension associated with kidney transplant. This article reports a case of recent gingival enlargement associated with cyclosporine A and amlodipine given to a kidney transplant patient from the past 11 years.

Abstract
Gingival enlargement is a very common side effect associated with the administration of several drugs, mainly anticonvulsants, calcium channel blockers (CCBs), and immunosuppressants. Amlodipine (a CCB) is a safe antihypertensive drug with a longer duration of action. Gingival enlargement induced by amlodipine is less prevalent among CCBs. Since the pathogenesis is not well understood, it is still a challenge for clinicians to diagnose and manage cases effectively. This case presents an atypical unilateral palatal gingival enlargement in a 61-year-old hypertensive female taking amlodipine. Difficulty for a pathologist in diagnosing in spite of repeated sample submission from the lesion and repeated failure for the operator to reach the underlying pathology due to amlodipine-induced hyperplasia have also been discussed in this case report.

Abstract
Gingival overgrowth (GO) is one of the common findings in clinical practice. There could be several causes including drugs associated with the GO. Carbamazepine (CBZ) and amlodipine are the drugs which are infrequently documented as a cause in inducing the gingival hyperplasia. Certain drugs in the body fluid might limit the population of plaque bacteria and alter their metabolism that in turn induce the inflammatory mediators and also activate the genetic and biochemical factors responsible for gingival fibroblast growth. Drug-induced GO is a side effect with a multifactorial etiology that seems to orchestrate the interaction between drugs and fibroblasts in the gingiva. We describe a case of trigeminal neuralgia with hypertension treated with multiple drugs including amlodipine and CBZ. Although amlodipine is known to be infrequently associated with GO, an association of CBZ with GO is even rarer. Causality analysis on the World Health Organization Uppsala Monitoring Centre's scale indicates a probable association with offending drugs.

Abstract
INTRODUCTION Gingival overgrowth, a known side effect of calcium channel blockers, particularly nifedipine, usually presents as a diffuse overgrowth. An unusual presentation of amlodipine-induced gingival overgrowth is presented here, with a large, erythematous gingival mass as the most prominent feature, and rapid, almost complete resolution of the mass after reduction of amlodipine dosage. CASE PRESENTATION A boy, aged 7 years, presented with a gingival mass first noticed a week previously, with no associated discomfort or bleeding. His medical history was significant for Wiskott-Aldrich syndrome, bone marrow transplant 5 years previously, and subsequent development of severe chronic graft-versus-host-disease. His medication included: 1) amlodipine; 2) enalapril; 3) tacrolimus; 4) sulfamethoxazole/trimethoprim; 5) voriconazole; 6) hydrocortisone cream; and 7) intravenous immunoglobulin infusions. Allergies included: 1) vancomycin; 2) metoclopramide; 3) clonidine; and 4) latex. Examination revealed mild generalized gingival overgrowth and the presence of a large, erythematous, sessile, soft, non-tender mass on the mandibular right gingiva between the primary lateral incisor and canine, resembling a pyogenic granuloma. No suppuration, bleeding on probing, or radiographic abnormalities were noted. A recommendation was made to the physician of the patient to replace amlodipine with a different class of antihypertensive. In response, amlodipine dosage was decreased by 50% to 2.5 mg daily. At a 2-week follow-up visit, considerable reduction in size of the gingival mass had occurred, and shortly after complete resolution was reported by his parents. No other intervention, such as scaling or excision, had been performed. CONCLUSION Discontinuation or reduction of the amlodipine dose to <5 mg daily prior to any surgical intervention should be considered in patients taking amlodipine presenting with a gingival mass.

Abstract
Gingival overgrowth occurs mainly as a result of certain anti-seizure, immunosuppressive, or antihypertensive drug therapies. Excess gingival tissues impede oral function and are disfiguring. Effective oral hygiene is compromised in the presence of gingival overgrowth, and it is now recognized that this may have negative implications for the systemic health of affected patients. Recent studies indicate that cytokine balances are abnormal in drug-induced forms of gingival overgrowth. Data supporting molecular and cellular characteristics that distinguish different forms of gingival overgrowth are summarized, and aspects of gingival fibroblast extracellular matrix metabolism that are unique to gingival tissues and cells are reviewed. Abnormal cytokine balances derived principally from lymphocytes and macrophages, and unique aspects of gingival extracellular matrix metabolism, are elements of a working model presented to facilitate our gaining a better understanding of mechanisms and of the tissue specificity of gingival overgrowth.

Abstract
Antiphospholipid antibody (APLA) syndrome is a noninflammatory autoimmune disease, with innumerable clinical manifestations ranging from recurrent thrombosis and pregnancy morbidity to valvular lesions, transverse myelitis, thrombocytopenia, and hemolytic anemia. APLAs in antiphospholipid syndrome (APS) are well-known risk factors for cerebrovascular accidents. Stroke is the most common manifestation of APS in the central nervous system. Gingival enlargement is a known side effect of phenytoin which is an antiepileptic drug. This can have a significant effect on the quality of life as well as increasing the oral bacterial load by generating plaque retention sites. The management of gingival overgrowth seems to be directed at controlling gingival inflammation through a good oral hygiene regimen. Thus, this case report aims to describe the conservative management of phenytoin-induced gingival enlargement combined with inflammatory enlargement in a patient with APLA syndrome.

Abstract
About 85-94% of the Spanish adults older than 35 experience gum problems, and about 15-30% suffer from periodontitis, being severe in up to 5-11% of them. Unlike other inflammatory conditions, periodontal disease rarely causes discomfort, or limits life or causes functional limitations until its advanced stages, when clinical signs and symptoms arise (gingival recession, pathological teeth migration, or mobility). Lack of knowledge about the disease, together with the idea that tooth loss is linked to ageing, frequently results in a late diagnosis, requiring extensive treatments with a worse prognosis. At Primary Care level, there is series of drugs have been related to periodontal disease (anticonvulsants, immunosuppressive drugs, and calcium channel blockers) as secondary effects, which vary as regards their frequency and severity depending of the amount of accumulated plaque. Stress and depression have also been reported to alter the immune response and to increase the inflammatory response as well as periodontal susceptibility. Certain systemic conditions, such as diabetes mellitus, cardiovascular disorders, respiratory diseases, as well as low-weight pre-term birth, have also been linked to periodontitis.

Abstract
Cyclosporine is a selective immunosuppressant that has a variety of applications in medical practice. Like phenytoin and the calcium channel blockers, the drug is associated with gingival overgrowth. This review considers the pharmacokinetics, pharmacodynamics, and unwanted effects of cyclosporine, in particular the action of the drug on the gingival tissues. In addition, elucidates the current concepts in mechanisms of cyclosporine-induced gingival overgrowth. Clinical and cell culture studies suggest that the mechanism of gingival overgrowth is a result of the interaction between the drug and its metabolites with susceptible gingival fibroblasts. Plaque-induced gingival inflammation appears to enhance this interaction. However, understanding of the pathogenesis of gingival overgrowth is incomplete at best. Hence, it would be pertinent to identify and explore possible risk factors relating to both prevalence and severity of drug-induced gingival overgrowth. Newer molecular approaches are needed to clearly establish the pathogenesis of gingival overgrowth and to provide novel information for the design of future preventive and therapeutic modalities.

Abstract
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.

Abstract
Drug-induced gingival overgrowth is caused by the antiseizure medication phenytoin, calcium channel blockers, and ciclosporin. Characteristics of these drug-induced gingival overgrowth lesions differ. We evaluate the ability of a mouse model to mimic human phenytoin-induced gingival overgrowth and assess the ability of a drug to prevent its development. Lovastatin was chosen based on previous analyses of tissue-specific regulation of CCN2 production in human gingival fibroblasts and the known roles of CCN2 in promoting fibrosis and epithelial to mesenchymal transition. Data indicate that anterior gingival tissue overgrowth occurred in phenytoin-treated mice based on gross tissue observations and histomorphometry of tissue sections. Molecular markers of epithelial plasticity and fibrosis were regulated by phenytoin in gingival epithelial tissues and in connective tissues similar to that seen in humans. Lovastatin attenuated epithelial gingival tissue growth in phenytoin-treated mice and altered the expressions of markers for epithelial to mesenchymal transition. Data indicate that phenytoin-induced gingival overgrowth in mice mimics molecular aspects of human gingival overgrowth and that lovastatin normalizes the tissue morphology and the expression of the molecular markers studied. Data are consistent with characterization of phenytoin-induced human gingival overgrowth in vivo and in vitro characteristics of cultured human gingival epithelial and connective tissue cells. Findings suggest that statins may serve to prevent or attenuate phenytoin-induced human gingival overgrowth, although specific human studies are required.

Abstract
Drug-induced gingival overgrowth is a tissue-specific condition and is estimated to affect approximately one million North Americans. Lesions occur principally as side-effects from phenytoin, nifedipine, or ciclosporin therapy in approximately half of the people who take these agents. Due to new indications for these drugs, their use continues to grow. Here, we review the molecular and cellular characteristics of human gingival overgrowth lesions and highlight how they differ considerably as a function of the causative drug. Analyses of molecular signaling pathways in cultured human gingival fibroblasts have provided evidence for their unique aspects compared with fibroblasts from the lung and kidney. These findings provide insights into both the basis for tissue specificity and into possible therapeutic opportunities which are reviewed here. Although ciclosporin-induced gingival overgrowth lesions exhibit principally the presence of inflammation and little fibrosis, nifedipine- and especially phenytoin-induced lesions are highly fibrotic. The increased expression of markers of gingival fibrosis, particularly CCN2 [also known as connective tissue growth factor (CTGF)], markers of epithelial to mesenchymal transition, and more recently periostin and members of the lysyl oxidase family of enzymes have been documented in phenytoin or nifedipine lesions. Some oral fibrotic conditions such as leukoplakia and oral submucous fibrosis, after subsequent additional genetic damage, can develop into oral cancer. Since many pathways are shared, the study of gingival fibrosis and comparisons with characteristics and molecular drivers of oral cancer would likely enhance understandings and functional roles of molecular drivers of these oral pathologies.

Abstract
Drug-induced gingival overgrowth is frequently associated with three particular drugs: phenytoin, cyclosporin, and nifedipine. As gingival enlargement develops, it affects the normal oral hygiene practice and may interfere with masticatory functions. The awareness in the medical community about this possible side effect of nifedipine is less when compared to the effects of phenytoin and cyclosporin. The frequency of gingival enlargement associated with chronic nifedipine therapy remains controversial. Within the group of patients that develop this unwanted effect, there appears to be variability in the extent and severity of the gingival changes. Although gingival inflammation is considered a primary requisite in their development, few cases with minimal or no plaque induced gingival inflammation have also been reported. A case report of gingival overgrowth induced by nifedipine in a patient with good oral hygiene and its nonsurgical management with drug substitution is discussed in this case report.

Abstract
Medication-related gingival enlargement is a common reactionary phenomenon that occurs with the use of several types of therapeutic agents, including antiepileptic drugs (AEDs). This disorder has been documented since 1939, shortly after the introduction of phenytoin. In the present case, a concise review of literature concerning the etiopathogenesis and management of AEDs (phenobarbitone and phenytoin) induced gingival enlargement has been described. It is vital that not only the periodontist, but also dental surgeons and medical practitioners should become aware of the potential etiologic agents, characteristic features, and the differential diagnosis of drug induced gingival enlargement in order to be able to prevent, diagnose and successfully manage the condition.

Abstract
Background: Epilepsy is described as a chronic neurological disorder characterized by recurrent seizures of cerebral origin, presenting with episodes of sensory, motor or autonomic phenomenon with or, without loss of consciousness. A recent meta-analysis of published and unpublished studies puts an overall prevalence rate of epilepsy in India at 5.59 per 1,000 populations. There have been studies that report clinical benefits of the use of folic acid as an adjuvant to the anti-epileptic therapy in the prevention of anti-epileptic drug induced gingival enlargement. However, studies conducted in the past have also reported precipitation of epileptic attacks in patients on folic acid adjuvant therapy due to fall in sera levels of phenytoin due to drug interactions. The study was planned to investigate the association of phenytoin induced gingival enlargement and sera levels of folic acid in epileptic patients on phenytoin therapy so as to justify the use of folic acid as a routine adjuvant to the usual anti-epileptic therapy to prevent this inevitable adverse effect without destabilizing the ongoing regimen leading to the precipitation of seizures in an otherwise stable patient (breakthrough seizures). Materials and Methods: A total of 100 patients between the ages 18 and 50 years were clinically diagnosed with epilepsy prior to the start of phenytoin therapy were included based on selection criteria and written informed consents were obtained. Assessment of serum folic acid levels and gingival enlargement was performed prior to the start of and after 1 year of phenytoin therapy. Statistical Analysis Used: The statistical analysis was carried out using t-test and the baseline serum folate levels and the serum folate levels obtained after 1 year of phenytoin therapy were correlated with the respective grades of gingival enlargement using Pearson's coefficient formula. Results: The results of the study confirmed a significant association between low serum folate levels with increasing severity as well as an early onset of phenytoin induced gingival enlargement. Conclusions: The results of the study suggest a higher incidence of gingival enlargement with an early onset and increased severity in phenytoin treated epileptic patients with a positive correlation with falling serum folic acid levels as the duration of the therapy increases.

Abstract
BACKGROUND Drug-induced gingival overgrowth is a common finding in the modern era. These gingival overgrowths are usually treated by various modalities namely substitution of drugs, surgical, and non-surgical treatment. The recent concept mainly involves full-mouth scaling and root planing (the entire dentition in two visits within 24 hours, i.e., two consecutive days) followed by chair side mouth rinsing by the patient with a 0.2% chlorhexidine solution for 2 minutes and brushing the tongue of the patient with 1% chlorhexidine gel. This is followed by an additional subgingival irrigation (three times, repeated within 10 minutes) of all pockets with a 1% chlorhexidine gel. MATERIALS AND METHODS Twenty patients between the ages of 20 and 50 years with drug-induced gingival overgrowth were treated using the full-mouth disinfection approach. The patients were evaluated at 3 months and 6 months after therapy. The data obtained for plaque index, bleeding on probing index, probing pocket depth, and gingival overgrowth scores were tabulated and compared statistically using the one sample unpaired t test. STATISTICAL ANALYSIS Statistically significant difference (P < 0.05) was found in PI GBI, PPD, and GO score between baseline, 3 months, and 6 months. RESULTS All clinical parameters improved significantly after therapy without the need of further surgical treatment. CONCLUSIONS Full-mouth disinfection might be a beneficial treatment concept in patients with drug-induced gingival overgrowth, thus decreasing the need for surgical therapy.

Abstract
Background/Aims The most common cause of chronic periodontitis is poor oral hygiene. Gastroesophageal reflux disease (GERD) enhances the proximal migration of gastric contents and may cause poor oral hygiene. We hypothesized that GERD may increase thse risk of chronic periodontitis and investigated this potential relationship. Methods A retrospective cross-sectional study was conducted in outpatients between January 1, 2010, and April 30, 2012. GERD was defined as being present based on at least two of the following criteria: etiologic agent(s), identifiable signs and symptoms, and consistent anatomic alterations. A total of 280 patients with chronic periodontitis and 280 controls were analyzed. Information regarding patient demographics and other potential confounding factors for chronic periodontitis were collected through individual medical records. Results GERD was revealed to be independently associated with an increased incidence of chronic periodontitis (odds ratio [OR], 2.883; 95% confidence interval [CI], 1.775 to 4.682). The other three variables of dental caries (OR, 1.531; 95% CI, 1.042 to 2.249), tobacco use (OR, 2.335; 95% CI, 1.461 to 3.730), and history of medication (calcium channel blocker, cyclosporine, or phenytoin) (OR, 2.114; 95% CI, 1.160 to 3.854) were also determined to be independent risk factors. Conclusions The present study supported our hypothesis that GERD can be a risk factor for chronic periodontitis.

Abstract
Gingival enlargement is a common clinical feature of gingival and periodontal diseases. It is an unwanted side effect of certain systemic drugs given for nondental treatment. It is being reported with three main groups of drugs like calcium channel blockers (CCBs), immunosuppressants, and anticonvulsants. Among calcium channel blockers, nifedipine causes gingival hyperplasia in about 10% of patients, whereas the incidence of amlodipine-, a third generation calcium channel blocker, induced gingival hyperplasia is very limited. There are very few reports of amlodipine-induced gingival enlargement at a dose of 5 mg. We report a case of amlodipine-induced gingival enlargement in a 45-year-old hypertensive patient taking amlodipine at a dose of 5 mg.

Abstract
Drug-induced gingival overgrowth or enlargement manifests as abnormal growth of the gingiva due to an adverse drug reaction (ADR) in patients treated with anticonvulsants, immunosuppressants, and calcium channel blockers. As gingival enlargement develops, it affects the normal oral hygiene practice and may interfere with masticatory functions. It gradually becomes a source of pain and the condition often leads to disfiguration. Within the group of patients that develop this unwanted effect, there appears to be variability in the extent and severity of the gingival changes. It would seem pertinent to identify and explore possible risk factors and relating them with the treatment plan. This article throws light on respective drugs and their association with gingival overgrowth and approaches to treatment based on current knowledge and investigative observations.

Abstract
Connective tissue growth factor (CCN2/CTGF) mediates transforming growth factor-β (TGF-β)-induced fibrosis. Drug-induced gingival overgrowth is tissue specific. Here the role of the phosphoinositol 3-kinase (PI3K) pathway in mediating TGF-β1-stimulated CCN2/CTGF expression in primary human adult gingival fibroblasts and human adult lung fibroblasts was compared. Data indicate that PI3K inhibitors attenuate upregulation of TGF-β1-induced CCN2/CTGF expression in human gingival fibroblasts independent of reducing JNK MAP kinase activation. Pharmacologic inhibitors and small interfering (si)RNA-mediated knockdown studies indicate that calcium-dependent isoforms and an atypical isoform of protein kinase C (PKC-δ) do not mediate TGF-β1-stimulated CCN2/CTGF expression in gingival fibroblasts. As glycogen synthase kinase-3β (GSK-3β) can undergo phosphorylation by the PI3K/pathway, the effects of GSK-3β inhibitor kenpaullone and siRNA knockdown were investigated. Data in gingival fibroblasts indicate that kenpaullone attenuates TGF-β1-mediated CCN2/CTGF expression. Activation of the Wnt canonical pathways with Wnt3a, which inhibits GSK-3β, similarly inhibits TGF-β1-stimulated CCN2/CTGF expression. In contrast, inhibition of GSK-3β by Wnt3a does not inhibit, but modestly stimulates, CCN2/CTGF levels in primary human adult lung fibroblasts and is β-catenin dependent, consistent with previous studies performed in other cell models. These data identify a novel pathway in gingival fibroblasts in which inhibition of GSK-3β attenuates CCN2/CTGF expression. In adult lung fibroblasts inhibition of GSK-3β modestly stimulates TGF-β1-regulated CCN2/CTGF expression. These studies have potential clinical relevance to the tissue specificity of drug-induced gingival overgrowth.

Abstract
Gingival overgrowth (GO) is among one of the most important clinical features of gingival pathology frequently seen in periodontal clinic. Amlodipine is a comparatively new calcium channel blocker and is being used with increasing frequency in the management of hypertension and angina. A 48-year-old Indian woman who was on amlodipine for 3 years for hypertension reported to the department of periodontics with the complaint of swollen, un esthetic gums. The patient developed GO 6 months before her first visit to dental hospital. She developed GO very rapidly due to the increase in amlodipine dose due to the severe angina attack 6 months before and due to the use of cholesterol (CHO) lowering drug. The main aim of the case report is to study the severity of amlodipine induced GO in a patient with cardiovascular disease (CVD) and to identify the role of subgingival microorganisms on inflammatory gingival enlargement in the same patient. The severity and rapidity of gingival enlargement in this report could have been triggered by doubling the dose of amlodipine and concomitant use of CHO lowering drug.

Abstract
Despite the popularity and wide acceptance of the calcium channel blockers (CCBs) by the medical community, their oral impact is rarely recognized or discussed. CCBs, as a group, have been frequently implicated as an etiologic factor for a common oral condition seen among patients seeking dental care: drug-induced gingival enlargement or overgrowth. This enlargement can be localized or generalized, and can range from mild to extremely severe, affecting patient's appearance and function. Treatment options for these patients include cessation of the offending drug and substitution with another class of antihypertensive medication to prevent recurrence of the lesions. In addition, depending on the severity of the gingival overgrowth, nonsurgical and surgical periodontal therapy may be required. The overall objective of this article is to review the etiology and known risk factors of these lesions, their clinical manifestations and periodontal management.

Abstract
Gingival overgrowth/hyperplasia can be attributed to several causes, but drug-induced gingival overgrowth/hyperplasia arises secondarily to prolonged use of antihypertensive drugs, anticonvulsants and immunosuppressants. The management is complex in nature considering the multitude of factors involved such as substitution of drug strict plaque control along with excision of the tissue to be performed under local anesthesia as outpatient. In the recent times, the patient's psychological fear of the treatment with the use of surgical blade and multiple visits has developed the concept of single visit treatment under general anesthesia incorporating a laser as viable option. The present case highlights the new method of management of gingival overgrowth.

Abstract
Mast cells (MCs) are multifunctional effector cells that were originally thought to be involved in allergic disorders. Now it is known that they contain an array of mediators with a multitude of effects on many other cells. MCs have become a recent concern in drug-induced gingival overgrowth (DIGO), an unwanted outcome of systemic medication. Most of the studies have confirmed the significant presence of inflammation as a prerequisite for the overgrowth to occur. The inflammatory changes within the gingival tissue appear to influence the interaction between the inducing drug and the fibroblast activity. The development of antibodies to MC-specific enzymes, tryptase and chymase, has facilitated the study of mast cells in DIGO. Many immunohistochemical studies involving MCs have been conducted; as a result, DIGO tissues are found to have increased the number of MCs in the gingiva, especially in the area of fibrosis. At the cellular level, gingival fibrogenesis is initiated by several mediators which induce the recruitment of a large number of inflammatory cells, including MCs. The purpose of this paper is to access the roles played by MCs in gingival overgrowth to hypothesize a relationship between these highly specialized cells in the pathogenesis of DIGO.

BACKGROUND Drug-influenced gingival overgrowth is an unaesthetic overgrowth of gingiva principally associated with intake of drugs like phenytoin, cyclosporin A and nifedipine. Its occurrence in both dentate and edentulous regions of oral cavity is poorly understood. OBJECTIVES This report highlights clinical and histological description, aetiology and management of gingival overgrowth in a partially edentulous (non-denture wearer) 60-year-old female patient with epilepsy on phenytoin and phenobarbital drugs from past 7 years. MATERIALS AND METHODS Patient's intraoral examination revealed lobulated and fibrotic consistency gingival overgrowth around teeth and on partially edentulous ridges of upper and lower arches along with generalised tooth mobility. Under medical consultation, full mouth extraction, surgical excision of overgrowth followed by complete denture rehabilitation and replacement of combination drugs with sodium valproate were accomplished. RESULTS Histologically, the lesion showed fibro-epithelial hyperplasia. Clinical results after 6 months demonstrated almost complete resolution of gingival overgrowth. CONCLUSION The findings of present case suggest that gingival overgrowth can occur even in partially edentulous ridges (not exposed to denture wear) that could be due to persistence of gingival overgrowth, which may not resolve completely following tooth extraction or occurs because of incorporation of specific subpopulation of gingival fibroblasts in alveolar ridge mucosa.

Abstract
BACKGROUND AND OBJECTIVES The renin-angiotensin system (RAS) is considered as a hormonal circulatory system involved in maintaining blood pressure, electrolyte and fluid homeostasis. RAS components can be synthesized in local tissues and are found to play a role in gingival overgrowth. The drug-induced gingival overgrowth (DIGO) is a fibrotic condition, which is associated with multiple factors, including inflammation and adverse drug effects such as cyclosporine A. This study was directed forward to the identification of the angiotensinogen, angiotensin II (Ang II) and its receptors AT₁ /AT₂ expression in DIGO tissues and cyclosporine-treated human gingival fibroblast cells. MATERIAL AND METHODS Gingival samples were obtained from patients with cyclosporine-induced gingival overgrowth, chronic periodontitis and normal healthy subjects. The total RNA was isolated and reverse transcription-polymerase chain reaction was performed for angiotensinogen, Ang II and AT₁ /AT₂ receptor. Ang II protein was estimated from tissue by enzyme immunoassay. The expression of Ang II and its receptors were also examined in gingival fibroblast cells treated with cyclosporine. RESULTS Ang II mRNA and protein expression was significantly higher in patients with DIGO than in patients with periodontitis and healthy subjects. The AT₁ mRNA was expressed more than AT₂ in all examined tissues. In gingival fibroblasts, Ang II and AT₁ expressions were increased with cyclosporine incorporation compared to controls. CONCLUSION These results suggest that cyclosporine can modulate local expression of RAS components such as angiotensinogen, Ang II and its receptors in gingival tissues and gingival fibroblast cells.
