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
<br/> Drug-influenced gingival enlargement (DIGE) is a reaction to specific medications, namely phenytoin, ciclosporin and calcium channel blockers. DIGE is encountered increasingly in clinical practice due to the widespread use of calcium channel blocker drugs particularly. Approaches to its management are discussed in this review.<br/> Methods: Narrative review of the literature and discussion of clinical implications.<br/> Findings: Management of DIGE involves nonsurgical treatment and may require surgical reduction of the overgrown gingival tissues. Management is complicated by the difficulties in achieving adequate plaque control, given the unfavourable contour of the enlarged gingival tissues, and the high frequency of recurrence of DIGE after surgical management. Replacing the drug involved can be very beneficial in selected cases, but the management of the underlying medical condition limits its application. The decision to replace a drug is not the responsibility of the dental practitioner, but the patient's physician may make it after consultation.<br/> Conclusions: Management of DIGE can be challenging and may require close co-operation between the dental practitioner and a hygienist, a periodontist and the patient's physician. Long term supportive maintenance programmes need to be in place for optimal outcomes.

Abstract
OBJECTIVE To evaluate the effect of periodontal treatment on gingival overgrowth in a group of renal transplant patients. SUBJECTS AND METHODS Twenty-five renal transplant recipients receiving immunosuppressive therapy with cyclosporine A (CsA) were randomly assigned to 2 groups. Group 1 (n = 15) included patients who had been specifically referred to a dental clinic to prevent gingival overgrowth and were given full periodontal therapy. Group 2 (n = 10) was comprised of patients who did not receive any professional periodontal cleaning. Patients from both groups were examined to determine their periodontal status before and after 3, 6 and 12 months in terms of their plaque index, gingival index and gingival overgrowth. During the examination, their overall health was stable. RESULTS For group 1, the scores were 1.89 (baseline), 0.98 (6 months) and 0.56 (12 months), and hence there were significant reductions (p = 0.0001). The gingival indices were 1.71 (baseline), 0.76 (6 months) and 0.35 (12 months), and the reductions were also significant (p = 0.0001). A significant association was observed between poor oral hygiene and the degree of gingival overgrowth. The 1-year post-treatment follow-up showed that patients in group 1 did not develop gingival overgrowth due to the use of CsA as group 2 did without prior periodontal therapy. CONCLUSION Oral hygiene status was the most important variable related to the development and degree of gingival overgrowth due to the use of CsA.

Abstract
Gingival enlargement is a well recognized unwanted effect associated mainly with anticonvulsant drugs, immunosuppressant drugs and calcium channel blockers. Amlodipine influenced gingival enlargement is comparatively less prevalent amongst calcium channel blockers. It causes aesthetic disfigurement, speech disturbances, abnormal tooth movement and difficulty in mastication. The management of drug influenced gingival enlargement is a challenge for the periodontist, mainly due to less understanding of its pathogenesis, difficulties in selection of proper line of management and recurrence of the enlargement. This report discusses the importance of conservative approach (scaling and root planning along with drug replacement) in the management of a case of amlodipine influenced gingival enlargement. The need for extensive surgery was decreased after this approach.

Abstract
BACKGROUND AND OBJECTIVE We assessed the effects of cyclosporine A and nifedipine on the in vitro incorporation of [(35)S]sulfate into gingival fibroblast cell cultures derived from responder and nonresponder subjects who had received an organ transplant followed by a therapeutic regimen using a combination of those drugs. MATERIAL AND METHODS Gingival fibroblasts were isolated from responder and nonresponder subjects and maintained in vitro. Prior to cell harvest, gingival interleukin-1beta concentrations were determined by enzyme-linked immunosorbent assay (ELISA). Cells were untreated or exposed to either 10(-7)-10(-10) m nifedipine or 100-500 ng/ml cyclosporine A. Incorporation of [(3)H]proline or [(35)S]sulfate into the cell cultures was determined by liquid scintillation analysis. In addition, the effects of 400 ng/ml cyclosporine A + 10(-7) m nifedipine and 400 ng/ml cyclosporine A + 10(-10) m nifedipine on incorporation of [(35)S]sulfate into the cell cultures was determined. Data were compared by factorial analysis of variance (anova) and a posthoc Tukey's test. RESULTS Gingiva from responders contained significantly more interleukin-1beta than gingiva from nonresponders (p < 0.01). The cell cultures derived from responders incorporated significantly more [(35)S]sulfate than those derived from nonresponders following exposure to either cyclosporine A or 10(-7) m nifedipine. In addition, the exposure of fibroblasts derived from gingival overgrowth to either 400 ng/ml cyclosporine A + 10(-7) m nifedipine or 400 ng/ml cyclosporine A + 10(-10) m nifedipine significantly increased or decreased, respectively, the incorporation of [(35)S]sulfate into the cultures. CONCLUSION The therapeutic combination of cyclosporine A and nifedipine could be a significant risk factor for gingival overgrowth in subjects susceptible to either agent. The mechanism for overgrowth could include edema secondary to increased sulfated-glycosaminoglycan (sGAG) synthesis by fibroblasts, but further investigation is required.

Abstract
The administration of calcium channel blockers has been associated with gingival overgrowth. However, there are few studies in humans or animals that evaluated the effect of diltiazem on gingival tissues. The present study assessed the influence of diltiazem, at different dosages and treatment duration, on gingival tissues of rats, using clinical, histological and histometric analyses. Eighty young male rats were separated into eight groups according to the dosage and duration of treatment. Rats were treated for 20 or 40 days with a daily subcutaneous injection of 5, 20 or 50 mg/kg of body weight of diltiazem. The results confirmed that diltiazem did not induce gingival overgrowth in rats. For all animals, the evaluation did not show gingival alterations regardless of the dosages and periods of treatment. The histometric analysis showed no significant change in the area of epithelium and connective tissues, although after 40 days of treatment a decrease in the area of connective tissue was observed, without statistically significant difference from control groups. Within the limits of this study, we suggest that diltiazem did not induce gingival overgrowth.

Abstract
BACKGROUND The hypothesis that nifedipine-induced gingival enlargement in periodontitis patients can be treated with the adjunctive use of tetracycline (TCN) fibers was tested in this study. METHODS Ten patients (mean age 66 +/- 4 years) with chronic periodontitis combined with nifedipine-induced gingival enlargement participated. Full mouth recordings of clinical parameters (probing depth, clinical attachment level, bleeding on probing, presence or absence of plaque) were assessed at baseline and gingival enlargement was estimated from casts. Participants were instructed in proper oral hygiene and received supragingival scaling before being reassessed 1 month later. They subsequently received full-mouth scaling and root planing followed by the immediate placement of TCN fibers in all pockets >5 mm. Clinical parameters were reassessed at 3, 6, and 12 months after completion of treatment. RESULTS TCN fiber placement was well tolerated by patients. All clinical parameters recorded displayed significant improvements after treatment, and they were preserved for the 12-month experimental period. A significant reduction of the percentage of pockets >5 mm was noticed after treatment. The reduction of enlargement was still observed at 12 months despite patients not achieving optimal oral hygiene. CONCLUSION Placement of tetracycline fibers as an adjunct to mechanical treatment is an option for the non-invasive therapy of nifedipine-induced gingival enlargement in periodontitis patients whose general medical condition and concomitant ailments do not favor a surgical approach.

Abstract
OBJECTIVES This study was conducted to determine the prevalence and risk factors for gingival enlargement in patients treated with diltiazem or verapamil. MATERIAL AND METHODS A cross-sectional study was conducted and data from 46 patients actually taking diltiazem or verapamil were compared with 49 cardiovascular controls that never received any of these drugs. All patients were examined for the presence of gingival enlargement using two different indices, the vertical gingival overgrowth (GO) index, and horizontal Miranda & Brunet (MB) index in the inter-dental area. Gingival index, plaque index, and probing depth were also evaluated. RESULTS The total study population was 95:32 diltiazem-treated, 14 verapamil-treated and 49 cardiovascular control subjects. Gingival enlargement occurred in 31% (GO index) and 50% (MB index) of the patients taking diltiazem. Gingival enlargement in the verapamil-treated group was 21% for the GO index and 36% for the MB index. The prevalence of gingival enlargement was higher in the diltiazem- and verapamil-treated patients than in controls for both indices. The difference between the diltiazem-treated group and control was statistically significant (p=0.022 for GO and p=0.001 for MB), while the difference between the verapamil-treated group and controls was not significant. The risk of gingival enlargement (OR--Odds Ratio) associated with diltiazem therapy was 4.0 (1.2-13.1) for the GO index and of 6.0 (2.1-17.3) for the MB index. When the OR were adjusted for gingival index (GI) values, the risk of gingival enlargement was 3.5 (1.0-12.4) for the GO index and 6.2 (1.9-20.0) for the MB index. In the verapamil-treated group the OR values were not significant. The level of concordance between GO and MB indices in all three groups showed a kappa-value of 0.72 (p<0.001). CONCLUSION Patients taking diltiazem are at high risk for gingival enlargement and gingivitis has a stronger effect than the drug treatment on gingival enlargement risk.

Abstract
OBJECTIVES In the last few years, several studies have suggested that periodontal diseases are related to the development of atherosclerosis and its complications. Our objective was to study the ultrastructural morphology of the gingiva from cardiac patients, some of whom were treated and some not with calcium channel blockers compared to a control group. MATERIAL AND METHODS Fifty-five patients were studied and grouped in the following way: (a) healthy group (HG) (n=12) healthy patients with at least two pockets between 3 and 5 mm; (b) cardiac group (CG) (n=12) patients with cardiac disease untreated with calcium channel blockers; (c) diltiazem group (DG) (n=13) cardiac patients treated with diltiazem; (d) nifedipine group (NG) (n=18) cardiac patients treated with nifedipine. RESULTS Ultrastructural studies in the CG showed inflammatory cells, collagen fibers disruption and a more extended morphologically compromised fibroblast mitochondria. Morphometric studies in CG showed mitochondria that were impaired in number but increased in volume, suggesting metabolic cell suffering. In DG and NG, morphometric data were similar to HG. The presence of myofibroblasts and collagen neosynthesis was detected in DG and NG. CONCLUSIONS Our data showed differences in the ultrastructure of the gingival fibroblasts between the studied groups; the DG and NG showed features that could be interpreted as an attempt to restore the cellular metabolic function.

Abstract
OBJECTIVES To analyse the periodontal inflammatory infiltrates in patients with cardiac disease, some of these patients were treated with calcium antagonists (nifedipine and diltiazem) and some were not, to compare them with a healthy control group, and to evaluate the changes in the inflammatory infiltrate after periodontal treatment. MATERIAL AND METHODS A "healthy group" (HG, n=12), a "cardiac group" (CG, n=12) without treatment with calcium antagonists, a "nifedipine group" (NG, n=18) and a "diltiazem group" (DG, n=13) were analysed. Biopsies were taken from a zone 2-3 mm below the upper part of the interproximal papillae 12-13 and 33-32 before causal periodontal treatment and after 1 year. Using haematoxylin-eosin staining, the plasma cells (P), lymphocytes (L), histiocytes (H) and polymorphonuclear cells (PMN) were counted. T and B lymphocytes were evaluated using the monoclonal antibodies anti-CD20 and anti-CD45RO. Statistical tests used: chi2 for study of the sample composition; ANOVA for comparison between groups; Student t-test and Wilcoxon test for comparison between visits; post-hoc test Bonferroni. RESULTS When the cells were compared statistically, differences were established for L at the first visit (p<0.00001) and at the last visit (p<0.02), for the B lymphocytes (first visit p<0.0021, last visit p<0.022) and for the T lymphocytes (first visit p<0.0042, last visit p<0.0021). Between the 2 visits, HG showed significant reductions for P (p<0.01), L (p<0.045) and H (p<0.033); and the NG for L (p<0.0001). Lymphocytes showed differences in the NG with respect to the B lymphocytes (p<0.008). CONCLUSIONS Nifedipine affects the inflammatory infiltrate with a greater number of lymphocytes (especially B) and these cells fell significantly in number after periodontal treatment.

Abstract
There is an increasing number of medications associated with gingival overgrowth. These medications are used to treat a number of common conditions in the Australian population and as such dentists can expect to manage a number of patients with medication-related gingival overgrowth. This review highlights the clinical features and management of the common overgrowths associated with anticonvulsants, immunosuppressants and the calcium channel blockers.

Abstract
BACKGROUND Drug-induced gingival overgrowth (DGO) is one of the well-recognized side effects of cyclosporin A (CsA) or nifedipine (Ni). After surgical periodontal therapy, the incidence of DGO recurrence is not known. The aim of this study was to evaluate the results of surgical periodontal therapy in patients receiving CsA or Ni and who exhibit severe long-term DGO. In addition, the relationship between various variables and the recurrence of severe DGO after periodontal surgery was investigated. METHODS A total of 38 patients, 22 with CsA-induced DGO and 16 with Ni-induced DGO, were included in this study. At baseline, patients received initial periodontal therapy, after which either the upper or lower anterior segment in each patient was surgically treated. Surgical periodontal therapy consisted of the flap technique with a 90 degrees gingivectomy incision. Following surgery, patients were placed on a maintenance therapy recall program and were monitored for 18 months. Patients were seen once a month for the first 3 months and once every 3 months for the following 15 months. Plaque index (PI), papilla bleeding index (PBI) and DGO scores in the treated segments were recorded at each recall appointment. Attendance at recall appointments was also noted for each patient. RESULTS Recurrence of severe DGO was observed in 13 of the 38 patients (34%) 18 months following periodontal surgery. Multiple regression analysis indicated that age, gingival inflammation, and attendance at recall appointments were significant determinants of the recurrence of severe DGO. CONCLUSIONS This study suggests that regular re-motivation and professional care at frequent recall appointments after periodontal surgery are of great importance in patients receiving CsA or Ni. By maintaining periodontal health, the life quality of these patients may be raised.

Abstract
BACKGROUND Gingival hyperplasia (GH) is a major side effect associated with cyclosporin A (CsA) therapy. The condition is further augmented due to the gingival inflammation. In this study, the effects of initial periodontal therapy and gingival curettage are analyzed in a group of patients with clinically significant (>30%) CsA-induced gingival hyperplasia. METHODS The test group of 15 patients received oral hygiene instructions, supra- and subgingival scaling, polishing, and gingival curettage only oral hygiene instructions were given to 16 control subjects. Plaque index (PI), gingival index (GI), calculus index (CI), periodontal probing depth (PD), and gingival hyperplasia were recorded at baseline and repeated 8 weeks after treatment. Current doses of immunosuppressive agents, serum concentrations of CsA, and duration of CsA therapy were recorded as the pharmacological parameters. RESULTS Statistical evaluation revealed that all clinical variables showed statistical decreases compared to baseline in the treated patients, while none of the parameters changed significantly in the control group. Initial GH scores of 53.63% in controls and 53.40% in the treated patients were 52.83% and 32.13% following treatment, respectively. A difference of 21.27% in the severity of treated GH was accompanied by a 0.56 decrease in GI scores in the test group. CONCLUSIONS Compared to the initial observations, the results suggested that nearly 60% of the condition could be of fibrotic origin. Initial periodontal therapy and curettage resulted in the resolution of the inflammation in CsA-induced GH. Further investigation of the treated patients has shown that 7 out of 15 patients (47%) in the test group responded well and their GH scores decreased below 30% at the end of the study. The treatment in this study was effective in eliminating the necessity of more extensive surgical modes of treatment, such as gingivectomy, in 47% of cases.

Abstract
To clarify the possible pathophysiological role of medullasin, a neutrophil elastase-like proteinase, in nifedipine (NF)-induced gingival overgrowth, a rat model of gingival overgrowth was first established using a diet containing NF. The relation between histopathological changes and the distribution of the proteinase was then investigated. Thirty-two, specific pathogen-free 20 day-old, male, Fisher 344 rats were fed a diet containing NF and killed at 2, 8, 16 and 32 weeks. Control rats (n = 32) were fed the same diet but without the drug. The mandible of each rat was resected and sectioned at 4-microm thickness buccolingually between the first and second molars. Computer image analysis was used to evaluate the extent of overgrowth in the approximal gingiva of each sample. To examine medullasin activity, the mean percentage of medullasin-positive cells per total cells counted in the pocket epithelium and the connective tissue adjacent to the epithelium of approximal gingiva was determined immunohistochemically. The height of the mid-portion and the area in NF-treated group increased significantly with time (with the exception of area at 2 weeks) compared with the corresponding regions in the control group. A marked inflammatory-cell infiltration and elongated rete pegs, especially in the mid-portion of approximal gingiva, were seen in the NF-treated group. The mean percentages of medullasin-positive cells in the NF-treated group at 8, 16 and 32 weeks were significantly higher than those of the control. Although medullasin-positive cells were mainly neutrophils, in several samples of the NF-treated group they were recognized as macrophage-like. These findings suggest that medullasin may be involved in host defence and immunoregulation in a NF-induced rat model of gingival overgrowth.

Abstract
A number of idiopathic, pathological and pharmacological reactions may result in an overgrowth of the gingiva. This review concentrates on those overgrowths associated with various pharmacological agents. The pharmaco-kinetics and side effects of each drug associated with gingival overgrowth are discussed along with the clinical and histological features and treatment. By examining the possible pathogeneses for these overgrowths we propose a unifying hypothesis for the causation based around inhibition of apoptosis and decreased collagenase activity modulated by cytoplasmic calcium.
