Association of the severity and progression rate of periodontitis with systemic medication intake. FRONTIERS IN ORAL HEALTH 2024; 5:1447019. [PMID: 39157205 PMCID: PMC11328918 DOI: 10.3389/froh.2024.1447019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2024] [Accepted: 07/23/2024] [Indexed: 08/20/2024] Open
Abstract
Background/purpose Information on the systemic medication profiles of patients with periodontitis is limited. Therefore, this retrospective cross-sectional study aimed to analyze the relationship between the severity and rate of progression of periodontitis and systemic medication intake using a database of patients who attended the Clinic of Periodontics of the Faculty of Dentistry of the University of Costa Rica. Methods Electronic health records of patients diagnosed with periodontitis based on the Classification of Periodontal and Peri-Implant Diseases and Conditions (2017) were evaluated. Individuals were further categorized based on the severity (stage) and rate of progression (grade). Data extracted from the patient records included age, sex, and self-reported medication intake. Results In total, 930 records were included. Most of the studied population was middle-aged (36-64 years old); 43.01% were male, and 56.99% were female. Four hundred and fifty-seven patients (49.14%) reported taking at least one systemic medication for a chronic condition. Regarding the periodontal treatment phase, 62.37% underwent steps 1-3, and 37.63% underwent step 4. The most common systemic medications taken were for cardiovascular diseases (42.28%), followed by medications for diabetes (14.46%) and neurologic disorders (14.46%). Most patients (59.35%) were diagnosed with Stage III periodontitis. Grade B (48.28%) was the most prevalent. Calcium channel blockers demonstrated a disease severity-dependent association with the periodontal stage (p = 0.021). In addition, systemic medications for diabetes mellitus were associated with periodontal disease severity and rate of progression (all Ps < 0.05). Conclusions This study provides indirect evidence of the association between systemic diseases and periodontitis. The positive association between medications used to treat diabetes and the severity and rate of progression of periodontitis may be due to the underlying disease rather than the medications per se.

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.

Abstract
In recent years, the practice of dentistry and periodontology has become complicated by several risk factors, including the treatment of an increasing number of patients with substance use disorder. This review presents an update in the current literature of the impact of illegal drug use on periodontal conditions and their possible effect as risk factors or indicators. The main illegal drugs that may have an impact on periodontal health and conditions are described, including their effect, medical manifestations, risks, and the overall effect on oral health and on the periodontium. Where available, data from epidemiologic studies are analyzed and summarized. The clinical management of periodontal patients using illegal drugs is reported in a comprehensive approach inclusive of the detection of illicit drug users, screening, interviewing and counseling, the referral to treatment, and the dental and periodontal management. With regard to the impact of illegal substance use on periodontal conditions, there is moderate evidence that regular long-term use of cannabis is a risk factor for periodontal disease, manifesting as a loss of periodontal attachment, deep pockets, recessions, and gingival enlargements. Limited evidence also shows that the use of cocaine can cause a series of gingival conditions that mostly presents as chemical induced-traumatic lesions (application of cocaine on the gingiva) or necrotizing ulcerative lesions. There is a scarcity of data regarding the impact of other drug use on periodontal health. There is evidence to suggest that regular long-term use of cannabis is a risk factor for periodontal disease and that the use of cocaine can cause a series of periodontal conditions. The dental treatment of subjects that use illegal substances is becoming more common in the daily clinical practice of periodontists and other dental clinicians. When the clinicians encounter such patients, it is essential to manage their addiction properly taking into consideration the impact of it on comprehensive dental treatment. Further studies and clinical observations are required to obtain sound and definitive information.

Abstract
Periodontal disease is an infection-driven inflammatory disease characterized by the destruction of tooth-supporting tissues. The establishment of chronic inflammation will result in progressive destruction of bone and soft tissue changes. Severe periodontitis can lead to tooth loss. The disease has complex pathogenesis with an interplay between genetic, environmental, and host factors and pathogens. Effective management consists of plaque control and non-surgical interventions, along with adjuvant strategies to control inflammation and disrupt the pathogenic subgingival biofilms. Recent studies have examined novel approaches for managing periodontal diseases such as modulating microbial signaling mechanisms, tissue engineering, and molecular targeting of host inflammatory substances. Mounting evidence suggests the need to integrate omics-based approaches with traditional therapy to address the disease. This article discusses the various evolving and future drug targets, including proteomics, gene therapeutics, vaccines, and nanotechnology in personalized periodontal medicine for the effective management of periodontal diseases.

Use of amnion-derived cellular cytokine solution for the treatment of gingivitis: A 2-week safety, dose-ranging, proof-of-principle randomized trial. J Periodontol 2021; 92:1317-1328. [PMID: 33586783 PMCID: PMC8518950 DOI: 10.1002/jper.20-0800] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 02/02/2021] [Accepted: 02/03/2021] [Indexed: 11/13/2022]
Abstract
Background A 6‐week Phase I clinical trial was performed to primarily evaluate the safety and secondarily determine the preliminary efficacy of a novel biological solution, ST266, comprised of a mixture of cytokines, growth factors, nucleic acids, and lipids secreted by cultured amnion‐derived multipotent progenitor cells on gingival inflammation. Methods Fifty‐four adults with gingivitis/periodontitis were randomly assigned to 1X ST266 or diluted 0.3X ST266 or saline topically applied on facial/lingual gingiva (20 µL/tooth). Safety was assessed through oral soft/hard tissue exam, adverse events, and routine laboratory tests. Efficacy was assessed by modified gingival index (MGI), bleeding on probing, plaque index, probing depth (PD), and clinical attachment level (CAL). Assessments were performed on day 0, 8, 12, and 42. ST266 and saline applied daily starting at day 0 through day 12 except weekend days. Plasma was analyzed for safety and proinflammatory cytokines, interleukin (IL)‐1β, IL‐6, tumor necrosis factor‐alpha, and interferon gamma. Gingival crevicular fluid (GCF) was analyzed for the same cytokines. Subgingival plaque was primarily analyzed by checkerboard DNA‐DNA hybridization. Comparisons with saline were modeled through a generalized estimating equations method adjusting for baseline. Results No safety concern was found related to ST266. Statistically significant reduction in MGI was noted at day 42 by 1X ST266 compared with saline (P = 0.044). PD and CAL were reduced by both doses of ST266 at day 42 (P <0.01) and by 1X ST266 at day 12 (P <0.05). GCF IL‐1β and IL‐6 levels were reduced by both doses of ST266 at day 12 (P <0.05, P <0.01, respectively). IL‐6 was also significantly reduced in plasma of both ST266 groups (P <0.05). Significant reductions in red complex bacteria were detected in both ST266 doses. Conclusions In this “first in human oral cavity” study, topical ST266 was safe and effective in reducing gingival inflammation in 6 weeks. Longitudinal studies with large sample sizes are warranted to assess the therapeutic value of this novel host modulatory compound in the treatment of periodontal diseases.

Abstract
OBJECTIVE We investigated the importance of reactive oxygen species (ROS) on developing gingival overgrowth (GO) and then introduced the antioxidant strategy to prevent, or even reduce GO. BACKGROUND Gingival overgrowth is a common side effect of the patients receiving cyclosporine A (CsA), an immune suppressant. Although it has been broadly investigated, the exact pathogenesis of the induced GO is still uncertain. METHODS We cultured human primary gingival fibroblasts and used animal model of GO to investigate the ameliorative effects of antioxidants on CsA-induced GO. To examine the CsA-induced oxidative stress, associated genes and protein expression, and the overgrown gingiva of rats by using immunocytochemistry, confocal laser scanning microscopy, real-time PCR, ELISA, gelatin zymography, gingival morphological, and immunohistochemical analysis. RESULTS We found for the first time that ROS was responsible for the CsA-induced oxidative stress and TGF-β1 expression in human primary gingival fibroblasts, as well as the GO of rats. The antioxidants (oxidative scavenger of vitamin E and an antioxidative enzyme inducer of hemin) ameliorated CsA-induced pathological and morphological alterations of GO without affected the CsA-suppressed il-2 expression in rats. CsA-induced oxidative stress, HO-1, TGF-β1, and type II EMT were also rescued by antioxidants treatment. CONCLUSIONS We concluded that CsA repetitively stimulating the production of ROS is the cause of CsA-GO which is ameliorated by treating antioxidants, including vitamin E and sulforaphane. Furthermore, the immunosuppressive effect of CsA is not interfered by antioxidant treatments in rats. This finding may thus help the clinician devise better prevention strategies in patients susceptible to GO.

Abstract
Abstract This trial evaluated the preemptive and postoperative effect of dexamethasone and ibuprofen on prevention of pain/discomfort, edema and interference in daily life in patients undergoing root coverage combined with subepithelial connective tissue graft (CAF + CTG). Twenty patients were randomly assigned as follows: NSAID Group: 400mg Ibuprofen 60 min preemptive + 400mg Ibuprofen postoperative; or SAID Group: 4mg Dexamethasone 60 min preemptive + 4mg Dexamethasone postoperative. The postoperative medication was administered 8 and 16 h post-surgery. Each patient received questionnaires based on a numeric scale (101-point numeric scale rate [NRS-101]) and multiple choice questions (four-point verbal rating scale [VRS-4]) about trans-operative pain/discomfort, hourly for 8 h after surgery and once a day for three days. A Visual Analogue Scale (VAS) for edema and interference in daily life during the 1st, 2nd, 3rd and 7th day was also answered. The degree of anxiety was rated statistically by the Chi-square test. The Mann-Whitney and Friedman tests were used for the other questionnaires. The surgery time and number of analgesic pills consumed were compared using Student’s t-test. Patients who used dexamethasone presented a trend toward less pain when compared to individuals who ingested ibuprofen, with a significant difference observed 3 h after the procedure (p<0.05). The use of dexamethasone also promoted less edema until the 2nd day and lower interference in daily life on the third day when compared with ibuprofen (p<0.05). We concluded that the use of dexamethasone as a preemptive and postoperative medication was more suitable as a drug therapeutic protocol for CAF + CTG.

Abstract
Gingival fibromatosis is a rare and heterogeneous group of disorders that develop as slowly progressive, local or diffuse enlargements within marginal and attached gingiva or interdental papilla. In severe cases, the excess tissue may cover the crowns of the teeth, thus causing functional, esthetic, and periodontal problems, such as bone loss and bleeding, due to the presence of pseudopockets and plaque accumulation. It affects both genders equally. Hereditary, drug-induced, and idiopathic gingival overgrowth have been reported. Hereditary gingival fibromatosis can occur as an isolated condition or as part of a genetic syndrome. The pathologic manifestation of gingival fibromatosis comprises excessive accumulation of extracellular matrix proteins, of which collagen type I is the most prominent example. Mutation in the Son-of-Sevenless-1 gene has been suggested as one possible etiological cause of isolated (non-syndromic) hereditary gingival fibromatosis, but mutations in other genes are also likely to be involved, given the heterogeneity of this condition. The most attractive concept of mechanism for drug-induced gingival overgrowth is epithelial-to-mesenchymal transition, a process in which interactions between gingival cells and the extracellular matrix are weakened as epithelial cells transdifferentiate into fibrogenic fibroblast-like cells. The diagnosis is mainly made on the basis of the patient's history and clinical features, and on histopathological evaluation of affected gingiva. Early diagnosis is important, mostly to exclude oral malignancy. Differential diagnosis comprises all pathologies in the mouth with excessive gingival overgrowth. Hereditary gingival fibromatosis may present as an autosomal-dominant or less commonly autosomal-recessive mode of inheritance. If a systemic disease or syndrome is suspected, the patient is directed to a geneticist for additional clinical examination and specialized diagnostic tests. Treatments vary according to the type of overgrowth and the extent of disease progression, thus, scaling of teeth is sufficient in mild cases, while in severe cases surgical intervention is required. Prognosis is precarious and the risk of recurrence exists.

Abstract
BACKGROUND Previous reports have demonstrated a higher prevalence of dental caries and periodontal disease in adults with inflammatory bowel disease (IBD), but similar data in children and adolescents do not exist. The aim of the study was to evaluate the status of dental caries, oral hygiene, gingival status and periodontal treatment needs of children with IBD. METHODS In this case-control study, 55 children on remission from a single outpatient IBD clinic, aged 4 to 18 years (12.27 ± 3.67 yr) and 55 matched systemically healthy controls of a dental practice were assessed prospectively. The evaluation included medical history, dental questionnaire in both groups, and previous and current medical therapy of children with IBD. Additionally, the decayed, missing, and filled tooth (dmf-t or DMF-T), simplified gingival, plaque control record and community periodontal treatment needs indices were evaluated. RESULTS Children with IBD compared with controls had a statistically significant (P < 0.001) higher dmf-t (2.95 versus 0.91) or DMF-T (5.81 versus 2.04) index and a higher gingival inflammation (simplified gingival, 40% versus 24%) although the respectively dental plaque index showed no significant difference (plaque control record, 42% versus 41%). Also, the community periodontal treatment needs was significantly higher compared with controls (P < 0.001); most of the patients with IBD needed treatment of gingivitis (47% versus 4%), and none of them had healthy periodontium (0% versus 69%). CONCLUSIONS The results of this case-control study demonstrate a higher frequency of dental caries, more clinical signs of gingival inflammation, and increased periodontal treatment needs in children and adolescents with IBD despite similar oral hygiene status.

Abstract
CONTEXT The Renin Angiotensin system has been implicated in the pathogenesis of Drug Induced Gingival Overgrowth (DIGO), a fibrotic condition, caused by Phenytoin, Nifedipine and Cyclosporine. AIM This study quantified Angiotensin II levels in gingival tissue samples obtained from healthy individuals, patients on Nifedipine manifesting/not manifesting drug induced gingival overgrowth. MATERIALS AND METHODS Gingival tissue samples were obtained from healthy individuals (n=24), patients on nifidipine manifesting gingival overgrowth (n= 18) and patients on nifidipine not manifesting gingival overgrowth (n=8). Angiotensin II levels were estimated in the samples using a commercially available ELISA kit. RESULTS Angiotensin II levels were significantly elevated in patients on Nifedipine manifesting gingival overgrowth compared to the other 2 groups (p<0.01). CONCLUSION The results of the study give an insight into the role played by Angiotensin II in the pathogenesis of drug induced gingival overgrowth.

Abstract
BACKGROUND Gingival overgrowth (GO) is a known side-effect of calcium channel blockers. Although there have been several case reports, few studies have examined the prevalence of nifedipine, diltiazem, and amlodipine. This study was conducted to determine the prevalence and risk factors for GO in patients treated with calcium channel blockers. MATERIALS AND METHODS A cross-sectional study was conducted in out patient Department of Medicine, Government Medical College, Calicut. 133 patients taking antihypertensives were examined for the presence of GO using two different indices: Vertical GO in 6 points around each tooth and horizontal Miranda-Brunet index in the interdental area. Gingival index (GI), plaque index, and probing depth were also evaluated. RESULTS The frequency of GO was significantly higher in nifedipine-treated cases than other drug groups. Frequency of GO was 75% for nifedipine, 31.4% for amlodipine and 25% for amlodipine + metoprolol. Higher gingival, plaque and calculus were observed in patients taking calcium channel blockers. Among the possible risk factors, only the GI showed a significant correlation with GO. CONCLUSIONS Patients taking antihypertensives had poor oral hygiene. Patients taking nifedipine showed a higher frequency of GO. Gingival inflammation acts as a predisposing factor.

Abstract
Inflammation is a protective response essential for maintaining human health and for fighting disease. As an active innate immune reaction to challenge, inflammation gives rise to clinical cardinal signs: rubor, calor, dolor, tumor and functio laesa. Termination of acute inflammation was previously recognized as a passive process; a natural decay of pro-inflammatory signals. We now understand that the natural resolution of inflammation involves well-integrated, active, biochemical programs that return tissues to homeostasis. This review focuses on recent advances in the understanding of the role of endogenous lipid mediators that modulate cellular fate and inflammation. Biosynthesis of eicosanoids and other lipids in exudates coincides with changes in the types of inflammatory cells. Resolution of inflammation is initiated by an active class switch in lipid mediators, such as classic prostaglandins and leukotrienes, to the production of proresolution mediators. Endogenous pro-resolving lipid mediators, including arachidonic acid-derived lipoxins, aspirin-triggered lipoxins, ω3-eicosapentaenoic acid-derived resolvins of the E-series, docosahexaenoic acid-derived resolvins of the D-series, protectins and maresins, are biosynthesized during the resolution phase of acute inflammation. Depending on the type of injury and the type of tissue, the initial cells that respond are polymorphonuclear leukocytes, monocytes/macrophages, epithelial cells or endothelial cells. The selective interaction of specific lipid mediators with G protein-coupled receptors expressed on innate immune cells (e.g. G protein-coupled receptor 32, lipoxin A4 receptor/formyl peptide receptor2, chemokine-like receptor 1, leukotriene B4 receptor type 1 and cabannoid receptor 2) induces cessation of leukocyte infiltration; vascular permeability/edema returns to normal with polymorphonuclear neutrophil death (mostly via apoptosis), the nonphlogistic infiltration of monocyte/macrophages and the removal (by macrophages) of apoptotic polymorphonuclear neutrophils, foreign agents (bacteria) and necrotic debris from the site. While an acute inflammatory response that is resolved in a timely manner prevents tissue injury, inadequate resolution and failure to return tissue to homeostasis results in neutrophil-mediated destruction and chronic inflammation. A better understanding of the complex mechanisms of lipid agonist mediators, cell targets and actions allows us to exploit and develop novel therapeutic strategies to treat human inflammatory diseases, including periodontal diseases.

Abstract
OBJECTIVE To identify factors associated with increased gingival inflammation in adults with systemic sclerosis (SSc, scleroderma). METHODS In this cross-sectional study, forty-eight adults with SSc received assessment of gingival inflammation using Löe and Silness gingival index (LSGI), measurement of oral aperture and evaluation of manual dexterity to perform oral hygiene using the Toothbrushing Ability Test, as well as completion of an oral health-related questionnaire. RESULTS Three explanatory variables in the final multiple predictor models for the LSGI outcome were statistically significant--manual dexterity to perform oral hygiene, flossing in the evening and SSc subtype, with higher (i.e., worse) LSGI score among those with impaired manual dexterity, not flossing in the evening and diffuse form of SSc. In addition, posterior teeth had higher LSGI scores compared with that of the anterior teeth after adjusting for other variables. CONCLUSIONS Results suggest that dental health professionals take manual dexterity into consideration when educating patients with SSc to improve their oral hygiene and educate them on paying more attention on cleaning their posterior teeth and the importance of flossing in the evening--especially those who only floss once a day or less often.

Abstract
Cyclosporin A(CsA) - induced gingival overgrowth(GO) is a current problem of tissue-specific mechanism which is still incompletely explained. The apoptotic process has been of particular interest like a new concept in the etiology of this unwanted effect. The aim of our study was to detect the level of apoptosis, expression bcl-2 and p53, associated with the different doses of CsA. in gingival stroma. A cohort of 84 kidney transplant recipients was divided into four subgroups based on average daily dose of therapeutically applied CsA (Neoral®), (100 mg, 125 mg, 150 mg and 175 mg). The control group consisted of 21 patients, clinically diagnosed with periodontitis, who were not subjected to any medicamentous treatment causing gingival overgrowth. The following indexes were analyzed: plaque index (PI), index of gingival inflammation (GI) according to Loe-Silnes, and gingival overgrowth index (GOI) according to MacGaw et al. The tissue samples were subjected to a semiquantitative analysis to detect apoptotical cells and immunohistochemically stained to detect the expression of the bcl-2 and p53 proteins. The difference in percentage of apoptotic cells between the group taking 175 mg and other subgroups, as well as the control group was statistically significant (p<0.05). There was a significant difference in percentage of expression bcl-2 between the 175 mg group compared to the other three subgroups and the control (p=0.001). However, a statistically significant positive correlation between the medicament dose, p53, apoptosis, and bcl-2 was registered (p<0.05). Inflammation plays the most important role in the induction of apoptosis and proliferation in gingival tissues.

Abstract
Cyclosporin A (CsA) has been used as an immunosuppressive drug to prevent organ transplant rejection and to treat autoimmune diseases. CsA has a proliferative effect on human gingival fibroblasts (HGF) in vitro. However, the molecular mechanisms underlying CsA-induced proliferation in HGF remain to be elucidated. This study was aimed to investigate the CsA responsive proteins in HGF using systematic proteomic approach. Cell viability was determined by MTT assay and reactive oxygen species (ROS) was measured by fluorescent spectrometer. Proteins profiled by two-dimensional gel electrophoresis (2-DE) were identified by matrix-assisted laser desorption ionization time-of flight (MALDI-TOF) and electrospray ionization quadrupole time-of-flight mass spectrometry (EIQ-TOF MS). To confirm the expression changes of proteins by proteomics analysis, Western blot was performed using specific antibody. CsA increased the cell viability of HGF in a dose- and time-dependent manner. Significantly, seventeen proteins were overexpressed in the CsA-treated HGF, whereas three proteins were found to be expressed less than the untreated cells. The identified proteins were mainly related with cell proliferation, metabolism, and oxidation. The overexpression of peroxiredoxin 1 (Prx 1) confirmed by Western blotting and reduction of cytosolic reactive oxygen species (ROS) levels in the CsA-treated HGF demonstrated that Prx 1 may play a crucial role in the HGF proliferation induced by CsA. Upregulation of Galectin 3 in CsA-treated HGF indicated that it is related to CsA-induced proliferation. These proteomic analysis data will provide an efficient approach in understanding the mechanisms of HGF proliferation by CsA.

Abstract
BACKGROUND The role of cyclosporin in the absence of calcium channel blockers and the associated risk variables of development and severity of gingival overgrowth have not yet been properly established. The present study was conducted to determine the effect of potential risk variables for gingival overgrowth severity in Brazilian renal transplant subjects medicated with cyclosporin in the absence of any calcium channel blockers. METHODS A cross-sectional study was conducted in a public hospital in Belo Horizonte, Brazil. Demographic, pharmacologic, and periodontal data, recorded from 194 subjects taking cyclosporin in the absence of calcium channel blockers, were analyzed using independent sample t, chi2 statistic, or Mann-Whitney U tests. The effects of potential risk variables of gingival overgrowth severity were determined using backward stepwise regression analysis. RESULTS The prevalence of clinically significant gingival overgrowth was 34.5% (N = 67). These subjects presented a significantly higher papillary bleeding index and a higher plaque index compared to those without clinically significant gingival overgrowth. When all demographic, pharmacologic, and periodontal data were evaluated in relation to gingival overgrowth severity, time since transplant, papillary bleeding index, serum cyclosporin concentration, and prednisolone and azathioprine dosages were significant in the univariate modeling (P <0.05) and remained significant when evaluated in the multivariate modeling (P <0.0001; adjusted R2 = 39.4%). CONCLUSIONS In the absence of calcium channel blockers, this study showed that pharmacologic variables, such as cyclosporin serum concentration, prednisolone and azathioprine dosages, and time since transplant, are strongly related to gingival overgrowth. In addition, the periodontal variable papillary bleeding index highlighted the primary role of inflammation on the pathogenesis and severity of gingival overgrowth.

Abstract
OBJECTIVE The purpose of this study was to identify the presence of periodontal microrganisms in 35 renal transplant patients before the transplant procedure. STUDY DESIGN At each time point, clinical parameters were recorded and subgingival plaque samples were collected from 4 different sites at days 30 and 90 after surgery. Samples were plated onto selective and nonselective media to determine total colony counts and the presence of putative periodontal pathogens. After transplant surgery, patients received immunosuppressive therapy. RESULTS Statistical analysis of the microbiologic data showed significant changes between time points. An increase in total counts of microrganisms was observed on day 90 after surgery. As a side effect of cyclosporine, 14 patients developed gingival overgrowth. Beta-hemolytic Streptococcus was more frequently detected in patients who did not present gingival overgrowth 90 days after surgery. CONCLUSION Quantitative and qualitative changes of the subgingival microflora can occur 90 days after transplant surgery, while patients are still under immunosupressive drugs.

Abstract
Drug-induced gingival overgrowth is a side effect associated with 3 types of drugs: anticonvulsants (phenytoin), immunosuppressive agents (cyclosporine A), and various calcium channel blockers for cardiovascular diseases. Gingival overgrowth is characterized by the accumulation of extracellular matrix in gingival connective tissues, particularly collagenous components with various degrees of inflammation. Although the mechanisms of these disorders have not been elucidated, recent studies suggest that these disorders seem to be induced by the disruption of homeostasis of collagen synthesis and degradation in gingival connective tissue, predominantly through the inhibition of collagen phagocytosis of gingival fibroblasts. The integrins are a large family of heterodimeric transmembrane receptors for extracellular matrix molecules. alpha2beta1 integrin serves as a specific receptor for type I collagen on fibroblasts, and alpha2 integrin has been shown to play a crucial role in collagen phagocytosis. Actin filaments, which are assembled from monomers and oligomers, are involved in collagen internalization after binding to integrins. Furthermore, the implication of intracellular calcium in the regulation of integrin-mediated binding activity and gelsolin activity, known as a calcium-dependent actin-severing protein, is also described. In this review, we focus on collagen metabolism in drug-induced gingival overgrowth, focusing on the regulation of collagen phagocytosis in fibroblasts.

Abstract
Gingival overgrowth is the enlargement of the attached gingiva due to an increased number of cells. The most prevalent types of gingival overgrowth in children are drug-induced gingival overgrowth, hereditary gingival fibromatosis (HGF), and neurofibromatosis I (von Recklinghausen disease). Gingival overgrowth induced by drugs such as phenytoin, nifedipine, and cyclosporin develops due to an increase in the connective tissue extracellular matrix. According to epidemiologic studies, it is more prevalent in male children and adolescents. There is an additive effect of those drugs on the degree of gingival overgrowth. Genetic heterogeneity seems to play an important role in the development of the disease. Functional difficulties, disfigurement, increased caries, and delayed eruption of permanent teeth are the main complications of drug-induced gingival overgrowth. HGF is the most common syndromic gingival enlargement in children. This autosomal dominant disease usually appears at the time of eruption of permanent dentition. Histologically, it is characterized by highly collagenized connective tissue. The most important complications are drifting of teeth, prolonged retention of primary dentition, diastemata, and poor plaque control. Neurofibromatosis I is an autosomal dominant disease more common in mentally handicapped individuals. Gingival overgrowth is caused by the formation of plexiform neurofibromas in the connective tissue of the gingiva. Plexiform neurofibromas are pathognomonic of the disease and consist of hypertrophic nerves arranged as lobules in the connective tissue. Complications of the disease are multiple and severe due to neurofibromas and their occasional malignant transformation.

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
BACKGROUND Fatty acid synthase (FAS) is the enzyme that synthesizes palmitate from malonyl-CoA and acetyl-CoA. Recent studies have shown that FAS is overexpressed in human cancers and that its activity is necessary for cell proliferation. Hereditary gingival fibromatosis (HGF) is a genetic disease manifested as a progressive enlargement of the gingiva. The pathogenesis of this condition is not understood; however, a proliferative advantage of HGF fibroblasts in comparison with cells from normal gingiva (NG) has been described. The aim of this study was to investigate the role of FAS in NG and HGF fibroblast proliferation. METHODS NG and HGF fibroblasts had their proliferative potential assessed by automated cell counting and immunocytochemistry against Ki-67 or proliferating cell nuclear antigen (PCNA). The production of FAS, androgen receptor (AR), and ErbB2 was analyzed by Western blot and the pattern of FAS expression studied by immunocytochemistry. FAS activity was blocked by the specific inhibitor cerulenin. RESULTS Higher proliferation rates were found in fibroblasts isolated from HGF than from NG. HGF fibroblasts with greater proliferative potential produced more FAS and AR than the cell lines with lower growth rates, and all studied cell lines produced similar amounts of the ErbB2 protein. In addition, the FAS inhibitor cerulenin was able to significantly reduce the proliferation of both NG and HGF cells. CONCLUSIONS These results show that FAS is expressed by gingival fibroblasts and that highly proliferative HGF cells produced more FAS and AR than the other fibroblast cell lines. Moreover, FAS inhibition significantly reduced both NG and HGF fibroblast growth, suggesting a role for the androgen-driven fatty acid biosynthesis in their proliferation.

Abstract
BACKGROUND Severe gingival overgrowth (GO) is induced in patients taking cyclosporin A (CsA) following organ transplantation. Determining which patient will develop GO is still not possible. The purpose of this study was to establish an association between CsA and gingival overgrowth in heart transplant patients taking into account periodontal and microbiological conditions. METHODS Thirty patients (10 female, 20 male; range: 13 to 67 years; mean age: 44.89) undergoing CsA treatment were evaluated using the gingival index (GI), plaque index (PI), probing depth (PD), and clinical attachment level (CAL). Subgingival samples collected from the deepest site of each quadrant and saliva samples were submitted to microbial analysis. All patients had at least 12 teeth. Exclusion criteria were the use of antibiotics and/or having undergone periodontal treatment 6 months prior to the study. Patients were divided in two groups: with gingival (GO+) and without gingival overgrowth (GO-). RESULTS There were no statistically significant differences between the GO+ and GO- groups when CsA dosage, time since transplant, GI, PI, PD, and CAL were compared. Microbiological examination of the subgingival samples detected the following microorganisms: Actinobacillus actinomycetemcomitans (23%), Porphyromonas gingivalis (36%), Prevotella intermedia (93%), Fusobacterium sp. (66%), Campylobacter rectus (30%), Micromonas micros (66%), enteric rods (0%), and yeasts (30%). A positive association between M. micros and the GO+ group was found (P < 0.001). Yeasts were detected in 30% of the subgingival and saliva samples. CONCLUSIONS Clinical parameters were not sufficient to determine which patients would develop GO. However, colonization by M. micros might play a role in the etiology of GO.

Abstract
BACKGROUND The objective of the present study was to investigate the effect of cyclosporin A (CsA) and azithromycin (AZI) on collagen metabolism in the gingiva of rats. METHODS Fifty 6-week-old male Sprague-Dawley (SD) rats (weight 120 to 150 g) were randomly distributed into five groups. All groups received various drugs via gastric feeding for 7 weeks. The first group (Mo group) received mineral oil for 7 weeks as a control; the CsA group received CsA in mineral oil for 7 weeks (dosage 30 mg/kg); the CsA/Mo group received CsA in mineral oil for 6 weeks and mineral oil only for the seventh week; the CsA/AZI group received CsA in mineral oil for 6 weeks and AZI (dosage 10 mg/kg) in mineral oil simultaneously with CsA in the seventh week; and the Mo/AZI group received mineral oil for 6 weeks and AZI in mineral oil for the seventh week. All animals were sacrificed for clinical and histological analyses. Gingival fibroblasts were cultured at the fourth passage, and the amount of collagen was measured. Type I collagen and collagenase mRNA were measured by reverse transcription-polymerase chain reaction. Collagen phagocytosis assay also was performed. RESULTS Clinically, CsA induced gingival overgrowth in rats, whereas AZI reduced gingival overgrowth. Histological results of the CsA group showed a marked increase of tissue volume compared to the other groups. High collagen amounts were found when gingival overgrowth was induced. However, type I collagen mRNA and collagenase mRNA expressions did not statistically differ among groups. Phagocytosis assay showed that CsA decreased phagocytic activity of gingival fibroblasts, whereas AZI increased the activity. These results suggest that the induction and reduction of CsA-induced gingival overgrowth were closely associated with phagocytic activity. CONCLUSION Cyclosporin A decreases collagen degradation by lowering phagocytic activity of rat gingival fibroblasts. Azithromycin partially compensates for this lowered phagocytic activity.

Abstract
Certain medical conditions and their accompanying drug treatment do have an impact upon oral structures and the delivery of dental care. Recent evidence suggests that oral health could be a significant risk factor for coronary artery disease. Many medical conditions can affect dental care are often over-stated and lack an evidence base. Examples include the need for antibiotic cover in patients at risk from infective endocarditis and the necessity to provide supplementary corticosteroids for those patients on longterm steroid therapy. By contrast, certain systematic drug treatments can have a profound affect on the oral tissue. The most obvious is drug-induced gingival overgrowth. Drugs frequently implicated in this unwanted effect include phenytoin, ciclosporin and the calcium channel blockers. Several risk factors for drug-induced overgrowth have been identified and include age, sex, peridontal variables and a range of drug pharmacokinetic variables. The relationship between oral health and coronary artery disease opens up a potentially new vista for the delivery of oral care. Although the association is convincing, casualty has not been established. If casualty for this relationship can be confirmed then the delivery of dental care and the promotion of oral health will receive a significant impetus.

Abstract
UNLABELLED Increasing numbers of children are receiving solid organ transplants namely kidney, liver, heart and lung. Patient survival rates following such transplants are essentially good with much of the success attributable to the development of Cyclosporine A (CyA), an immunosuppressive drug, that minimizes organ rejection. However the gingival overgrowth (GO) associated with the use of CyA is not only disfiguring but in paediatric recipients, may interfere with normal oral development and function. OBJECTIVE The aim of this review is to summarize current knowledge concerning the aetiology, pathogenesis and management of gingival overgrowth. METHODS Literature pertaining to gingival overgrowth is reviewed with particular reference to the paediatric population. Emphasis is placed on summarizing the evidence pertaining to the effectiveness of intervention. CONCLUSION CyA undoubtedly causes gingival overgrowth, the effects and levels of which appears to be more severe in younger patients. There is conflicting evidence as to the effectiveness of oral hygiene regimes, antibiotics and surgery in reducing overgrowth. The introduction of an alternative immunosuppressive agent (Tacrolimus) offers potential as it does not appear to cause overgrowth, although research to date is limited by the small sample size of many of the studies. This is an area in which multicentre studies would be of great value.

Abstract
OBJECTIVES The aim of this investigation is to study androgen metabolism in gingival fibroblasts in response to phenytoin, oestradiol and the antioestrogen tamoxifen, in order to establish the possible role of hormones in the aetiopathogenesis of phenytoin-induced gingival overgrowth. MATERIALS AND METHODS Six cell lines of human gingival fibroblasts were established in monolayer culture in Eagle's minimum essential medium. Duplicate incubations were performed independently with radiolabelled testosterone and 4-androstenedione, respectively (14C-T/14C-4-A), with optimal concentrations of phenytoin, oestradiol and tamoxifen alone and in combination. At the end of a 24-h incubation period, the medium was solvent extracted for steroid metabolites, which were separated by thin layer chromatography and quantified using a radioisotope scanner. RESULTS The substrates were metabolised mainly to the diols, 5alpha-dihydrotestosterone (DHT) and 4-androstenedione or testosterone, with the two substrates used. The trends were that phenytoin and oestradiol significantly elevated the yields of the androgens DHT, diols and 4-A/testosterone from both substrates while tamoxifen inhibited the stimulatory effects of oestradiol and phenytoin alone and in combination (n=6; p<0.01, one-way anova). CONCLUSION Specific hormone-mediated activity in response to phenytoin could contribute to the pathogenesis of gingival overgrowth, which can be decreased by the anti oestrogen tamoxifen.

Abstract
Keratinocyte growth factor stimulates the growth and activity of epithelial cells via the keratinocyte growth factor receptor. We have recently shown that the growth factor is markedly elevated in cyclosporin A-induced gingival hyperplasia tissue in vivo, but the effects of cyclosporin A on the receptor are not yet known. The present study was therefore carried out to determine whether expression of the keratinocyte growth factor receptor is up-regulated in gingival hyperplasia compared with normal gingiva. Using immunohistochemistry and the reverse-transcribed polymerase chain-reaction, we obtained results which showed that receptor antigen and gene transcript levels were both elevated in gingival hyperplasia tissue. In addition, flow cytometry and the reverse-transcribed polymerase chain-reaction showed that the receptor and mRNA were also higher in gingival epithelial cells following incubation with cyclosporin A in vitro. These findings suggest that the keratinocyte growth factor-receptor pathway of mesenchymal-epithelial interaction could play an important part in the molecular pathogenesis of gingival hyperplasia.

Abstract
The oral cavity may be the target organ for a number of diverse abnormalities that develop from side effects of medications. Because of the widespread and increasing use of prescription, over-the-counter, and herbal remedies, it is becoming increasingly likely that the dentist will encounter soft tissue or dental pathologies that represent a complication of a therapeutic agent. The more common abnormalities that may occur include gingival hyperplasia, tooth discoloration, candidiasis, chemical injuries, and altered taste perception. The dental practitioner is often the primary health care provider who can recognize, diagnose, treat, and/or prevent these conditions.

Abstract
BACKGROUND Cyclosporin A (CsA) is an immunosuppressive agent that is known to induce gingival overgrowth (GO). Pharmacological, genetic, immunologic, and inflammatory factors seem to be involved in the complex pathogenesis of drug-induced GO. Lymphocyte subpopulations in human gingival connective tissue have been implicated in the pathogenesis of inflammatory periodontal diseases. One purpose of this study was to quantify CD4, CD8-, CD57-, and epithelial membrane antigen (EMA)-positive cells in the gingiva of renal transplant recipients treated with CsA, and compare them to findings in healthy controls. A second aim was to correlate cell numbers with clinical findings. METHODS The study included 19 kidney recipients who were taking CsA and had significant GO (CsAGO+), 13 recipients who were taking CsA but showed no GO (CsAGO-), and 14 systemically healthy individuals with gingivitis (C). Sections from gingival biopsies were incubated with monoclonal antibodies for CD4, CD8, EMA, and CD57, and then analyzed using the avidin-biotin complex method. In each specimen, the mononuclear cell types were quantified and their distribution was evaluated in 3 separate tissue zones: S = subepithelial connective tissue beneath the sulcular epithelium; O = subepithelial connective tissue beneath the oral epithelium; and M = middle connective tissue. RESULTS There were no significant differences among the groups with respect to the numbers of CD4+ and CD8+ cells in each of the 3 zones (P >0.05). In zone S, the CsAGO+ group had significantly more EMA-positive cells than either the C or CsAGO- groups (P <0.05). There were significant differences among the groups regarding numbers of CD57+ (natural killer) cells in zone M, with the lowest cell numbers in the CsAGO+ patients (P<0.05). CONCLUSIONS The results showed that low numbers of natural killer cells are important in the expression of plaque-induced inflammatory changes in CsA-associated GO. It appears that these cells may influence the drug's ability to induce proliferative activity.

Abstract
BACKGROUND/AIMS Whereas accumulation of dentogingival plaque inevitably leads to inflammatory reactions in the adjacent gingival tissue, there is limited information with regard to factors influencing naturally occurring fluctuation between gingival health and disease. The major aims of the present study were to investigate site-specific associations between plaque and gingivitis as well as transition dynamics of naturally occurring gingivitis in smoking and non-smoking young adults. METHODS 65 systemically healthy young adults, 19 to 30 years old, participated. 33 volunteers smoked at least 20 cigarettes per day, whereas 32 subjects were non-smokers. Clinical periodontal conditions were assessed four times within a time period of 6 months. An ecological approach in data analysis as well as site-specific analyses considering the correlated structure of data were performed. RESULTS At the outset and after 6 months, smokers had significantly more supragingival plaque than non-smokers. At the final examination, bleeding upon probing as well as calculus were more prevalent in smokers. A site-by-site analysis revealed that smokers tended to have a weaker association between supragingival plaque and bleeding on probing than non-smokers (median Mantel-Haenszel's common odds ratio 1.91 vs. 2.89, p=0.07). Multiple logistic regression analyses adjusted for periodontal probing depth, plaque and calculus identified smoking status to significantly increase the risk for the first transition of non-bleeding to bleeding upon probing by 86% (p<0.01). In contrast, recovery of bleeding sites was positively influenced by female gender, but not smoking. CONCLUSIONS In multivariate analyses adjusted for probing depth, plaque and calculus, smokers appeared to be at higher risk for the transition from non-bleeding to bleeding on probing. Weaker associations between plaque and naturally occurring gingivitis in smokers may have important consequences for preventive strategies for gingivitis.

Abstract
BACKGROUND/AIMS Smoking is a major risk factor for destructive periodontal disease. There is limited information with regard to effects of smoking in subjects with minimal periodontal destruction. The aim of the present investigation was to assess the development of gingival recession in young adult smokers and non-smokers. METHODS 61 systemically healthy young adults, 19 to 30 years of age completed the final examination. 30 volunteers smoked at least 20 cigarettes per day, whereas 31 subjects were non-smokers. Clinical periodontal conditions were assessed 4x within a time period of 6 months. Site-specific analyses considering the correlated structure of data were performed. RESULTS At the outset, 50% of subjects presented with gingival recession at 1 or more sites. There was no significant difference in the prevalence of gingival recession between non-smokers and smokers. Severe recession in excess of 2 mm affected about 23% non-smokers but only 7% smokers. Some further gingival recession developed during the 6-month observation period. In a multivariate logistic regression analysis, the risk for recession development appeared not to be influenced by smoking status after adjusting for periodontal probing depth, recession at baseline, tooth brushing frequency, gender, jaw, tooth type and site. CONCLUSIONS Present data did not support the hypothesis that smokers are at an increased risk for the development of gingival recession.

Abstract
BACKGROUND Predictors of gingival enlargement in patients treated with anti-epileptics have not been previously assessed. This study was conducted to determine, with the aid of two indices that score vertical and horizontal overgrowth, the prevalence and risk factors for gingival enlargement in patients treated with phenytoin and other anticonvulsant drugs. MATERIALS AND METHODS A cross-sectional study was conducted and data from 59 patients taking antiepileptics were compared with 98 controls. Gingival enlargement was evaluated with two indices to score vertical overgrowth [Gingival overgrowth index (GO] and horizontal overgrowth [Miranda-Brunet index (MB)]. Gingival index, plaque index, and probing depth were also evaluated. RESULTS The prevalence of gingival enlargement was significantly higher (P < 0.0001) for both indices in the anticonvulsants treated groups than in the control group. Gingival overgrowth was significantly higher for both indices in the phenytoin group than in the non phenytoin group. Among the possible risk factors, only the gingival index showed a significant association with gingival enlargement. For the MB index the risk of gingival enlargement (odds ratio) associated to phenytoin therapy and other anticonvulsants therapy were 52.6 (13.5-205) and 6.6 (1.5-28.2). Gingival index-adjusted odds ratios for the same drugs were 5.7 (1.3-24.7) and 18.1 (2-158), respectively. The concordance between GO and MB indices in the control group and in the phenytoin-group and non phenytoin-group showed a Kappa value of 0.773 and 0.697, respectively. CONCLUSION This study reports significant differences in the prevalence and severity of gingival overgrowth in two groups of patients, one treated with phenytoin, and another treated with other anticonvulsants. Gingival inflammation is a significant risk factor for gingival enlargement in these patients.

Abstract
BACKGROUND The aim of this study was to determine and compare interleukin-6 (IL-6) levels in gingival crevicular fluid (GCF) and clinical periodontal findings in patients with rheumatoid arthritis (RA) and adult periodontitis (AP). METHODS A total of 45 patients divided into 3 groups (15 patients with RA and AP, 15 patients with AP, and 15 periodontally healthy subjects) were included in this study. Plaque index (PI), gingival index (GI), sulcus bleeding index (SBI), probing depth (PD), and attachment level (AL) values for each patient were recorded. Enzyme-linked immunosorbent assay for quantitative detection of IL-6 in each GCF sample was employed. RESULTS No significant difference could be detected between the RA and AP groups in the mean clinical parameter data except PI. Although the mean GCF IL-6 level in the RA group was the highest, no significant difference could be found among the groups. There was only a strong negative correlation between GCF IL-6 levels and GI scores in the RA group. CONCLUSIONS In the patients with RA, despite increased local tissue destruction potential due to autoimmunity and higher PI levels than in the AP patients, our findings suggest that medication including corticosteroid and non-steroidal anti-inflammatory drugs may decrease gingival inflammation, but the synthesis and degradation of IL-6 in gingival tissue of RA patients may be different. To our knowledge, this study is the first report determining GCF IL-6 levels in RA patients.

Abstract
In order to define the effects of chronic renal failure (CRF) in the progress of gingival inflammation, we studied 6 patients (4 male, 2 female) with CRF who were on chronic hemodialysis for 4.25 (range 1-15) years. Six healthy individuals, age and sex matched were used as controls. The protocol which we used comprised of two periods (a) a 40-day duration period of preparation and (b) a 28-day duration experimental period. During the (a) period, all subjects went through: (1) therapy of the chronic gingivitis and (2) complete control of dental plaque by oral hygiene. During the experimental period, all subjects were advised to avoid, for at least 21 days, any mechanical or chemical media of oral hygiene and went through photographing, recording of gingival index (GI), recording of plaque index (PII), and the collection and quantification of gingival crevicular fluid (GCF). On the 21st day, root planning and polishing were performed and subjects were advised to carry out oral hygiene. On the 28th day, all previous examinations (GI, PII, GCF) were repeated. In both patients and controls, GI, PII and GCF were increased on 7th, 14th and 21st day, without significant differences between the groups and returned to normal (close to zero point) on the 28th day. There are no significant differences between patients with CRF and normal controls in the evolution of experimental gingivitis. Therefore, chronic uremia has no effect on the defense of periodontal tissue against microbial plaque.

Abstract
BACKGROUND Previous reports in the literature have shown that non-steroidal anti-inflammatory drugs (NSAID) may affect osseous tissues by either stimulating or inhibiting bone formation. This effect can be drug specific and different NSAIDs may produce opposite results. There are also reports showing that NSAIDs inhibit bone loss due to inflammatory disease process. The purpose of this randomized, controlled, blinded, clinical investigation was to determine the effect of a one week course of postsurgical naproxen on the osseous healing in intrabony defects. METHODS Twenty-four vertical osseous defects in 24 patients were treated with either a bioabsorbable membrane plus twice daily postsurgical naproxen 500 mg for one week (test or GPN group) or with a polylactide bioabsorbable membrane alone (control or GA group). Twelve patients were included in each group. Treatment was performed on either 2- or 3-wall or combination defects. All measurements were taken from a stent by a calibrated, blinded examiner and open measurements were repeated at the 9-month second stage surgery. Power analysis to determine superiority of naproxen treatment showed that a 12 per group sample size would yield 87% power to detect a 2.0 mm difference and 64% power to detect a 1.5 mm difference. RESULTS Open defect measurements from baseline to 9 months showed a statistically significant (P < 0.05) mean defect fill of 1.96 +/- 1.27 mm and 2.04 +/- 1.71 for the GPN and GA groups, respectively. This corresponded to a mean defect fill of 42% and a mean defect resolution of approximately 75% for both groups. The differences between GPN and GA groups were not statistically significant (P > 0.05). Defect fill of > or = 50% was seen in 6 defects (50%) in the GPN group and in 5 defects (42%) in the GA group. CONCLUSIONS The administration of postsurgical naproxen failed to produce osseous healing that was statistically superior to that obtained with polylactide bioabsorbable membranes alone.

Abstract
Hereditary gingival fibromatosis (HGF) is an oral condition characterized by the enlargement of the gingiva of both the maxilla and mandible. To study the cell proliferation index of fibroblasts from HGF and normal gingiva (NG), cell cultures from 4 members of the same family with HGF and from 4 healthy patients were established. Our results obtained from 6 different cell proliferation assays clearly showed that the cell proliferation rate was significantly higher in fibroblasts from HGF than from normal gingiva. HGF and control fibroblasts in subconfluent culture densities were typically spindle, but in saturation density HGF cells were shorter than control cells. These data suggest that the higher proliferative index of HGF fibroblasts possibly has a role in the pathogenesis of gingival outgrowth in HGF patients.

Abstract
This chapter affirms that drugs and medicaments may have a profound effect on the periodontal structures. In some instances, such as drug-induced melanosis, the effect may be insignificant to the health of the patient. In other circumstances, drug-induced disorders may initiate painful, destructive disease processes that will not be successfully managed unless the causal role of drugs is recognized and altered. Finally, the clinician must remain aware of the contribution of drug-induced xerostomia and smoking to increased susceptibility to dental and periodontal diseases.

Abstract
During immunosuppression with cyclosporine, gingival overgrowth, a minor secondary effect, may appear in the first weeks of treatment. In certain cases it may affect the function and/or esthetic appearance in a manner intolerable to the patient. A new immunnosuppressive molecule, tacrolimus, presently used as a treatment of second choice to control acute corticoresistant rejection, may bring oral comfort to these patients, since it reduces gingival overgrowth to negligible levels.

Abstract
The present study was conducted to determine the clinical effects of nifedipine on the gingiva of 97 patients. Patients were examined for changes in periodontal status and divided into subgroups, based on their age, gender, duration of drug intake, presence/absence of plaque and gingival inflammation, and according to the presence and severity of gingival overgrowth. Gingival overgrowth was noticed in 29% of the patients. Among the recorded parameters, duration of drug intake, presence/severity of gingival inflammation, and gender seemed to have the greatest effect on the development of gingival overgrowth. Patients with higher gingival inflammation scores, those on nifedipine medication for more than 4 years, and males were likely to have an increased tendency for higher incidence and severity of gingival overgrowth. The findings of the present study suggest that nifedipine medication induces gingival overgrowth and that certain local factors are involved in the pathogenesis of drug-induced gingival overgrowth. However, individual ability and sensitivity to metabolize the drug and its metabolites also seem to be important etiological factors.

Abstract
Phenytoin is a commonly used anticonvulsant drug for the prevention of seizures. A common side effect of phenytoin (PHT) therapy is connective tissue hyperplasia, particularly in the oral cavity manifesting as gingival overgrowth. Our previous studies concerning the molecular mechanisms of drug-induced gingival overgrowth have demonstrated that PHT alters the normal tissue turnover/wound healing signal by causing changes in macrophage phenotype, resulting in the upregulation of essential polypeptide growth factors such as platelet-derived growth factor (PDGF). The cellular consequences of this elevation in growth factor have not been investigated. The present light and electron microscopic study of rat hyperplastic connective tissue and human gingival overgrowth induced by PHT treatment revealed the presence of numerous myofibroblasts. Cells identified as myofibroblasts were evident in all PHT-treated tissue samples and were characterized by an elongated fusiform cell shape, abundant cytoplasmic rough endoplasmic reticulum/polyribosomes, and accumulations of sub-plasmalemmal microfilaments containing spindle densities. These cells were never observed in control tissues. Myofibroblasts are associated with the later stages of tissue turnover, specifically with the transition from the granulation to the remodeling phases of the wound healing process. The presence of myofibroblasts in hyperplastic connective and gingival tissues induced by PHT treatment suggests that PHT exacerbates the normal tissue turnover/wound healing signals responsible for the appearance of myofibroblasts.
