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

Abstract
BACKGROUND The incidence of gingival overgrowth among renal transplant patients treated with cyclosporine A ranges from 13% to 84.6%, and the overgrowth is not only esthetic but also a medical problem. We studied the determination of association between TGF-β1 (TGFB1) gene polymorphism and gingival overgrowth in kidney transplant patients medicated with cyclosporin A. METHODS Eighty-four kidney transplant patients with gingival overgrowth and 140 control transplant patients without overgrowth were enrolled into the case control study. TGFB1 polymorphism was determined using the PCR-RFLP assay for +869T > C in codon 10 and +915G > C in codon 25 as well as TaqMan real-time PCR assays for promoter -800G>A and -509C > T SNPs. RESULTS In kidney transplant patients suffering from gingival overgrowth, mean score of gingival overgrowth was 1.38 ± 0.60, whereas in control subjects it was 0.0. The patients with gingival overgrowth were characterized by similar distribution of TGFB1 genotypes and allele in comparison to subjects without gingival overgrowth. Among 16 potentially possible haplotypes of TGFB1 gene, only four were observed in the studied sample of kidney transplant patients: G_C_T_G, G_T_C_G, G_C_C_C, and A_C_T_G, with similar frequency in patients with and without gingival overgrowth. CONCLUSION No association between the TGFB1 gene polymorphism and gingival overgrowth was revealed in kidney transplant patients administered cyclosporine A.

Abstract
OBJECTIVES Impaired homeostasis and fluid balance are important physiopathological alterations in patients with chronic renal failure which may adversely affect the fluid dynamics and health status of tissues and organs. There are insufficient data about this phenomenon in periodontal tissues. The aim of this study was to evaluate the fluid dynamics of gingiva in children with end stage renal failure (ESRF), correlating this entity with gingival health in the same patient group. DESIGN Fifteen paediatric ESRF patients undergoing peritoneal dialysis (test group) and 15 systemically healthy children (control group) who were without periodontitis participated in the study. Fluid dynamics of gingiva were assessed via the gingival crevicular fluid (GCF) volume and tissue osmotic pressure (GOP) levels in the groups. GCF volume was measured using a Periotron 8000, whereas GOP was measured using a digital osmometer. Silness and Löe Plaque index (PI) and, Löe and Silness gingival index (GI) scores were utilized to determine the gingival health status in the study population. RESULTS There were increases in the GCF volume and GOP of the test group compared to those of the control group (p<0.01). The PI and GI scores were higher in the test group than in the control group (p<0.01). Strong and positive correlations were found between GI and GCF volume, GI and GOP and, GCF volume and GOP in both groups (p<0.01). CONCLUSIONS Our findings suggest that the fluid dynamics of gingiva may alter in children with ESRF, and this phenomenon may consequently affect the gingival health of these patients.

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
Cyclosporine (CSA) is a commonly used immunosuppressive medication in pediatric transplantation. Drug-induced gingival overgrowth (DIGO) is a frequent side effect associated with CSA use and can impair the patient's ability to achieve good oral hygiene. This study tested the hypothesis that sonic tooth brushing and oral hygiene instruction can reduce the occurrence or severity of DIGO in CSA-treated pediatric renal transplant recipients. Twenty-three pediatric renal transplant patients with DIGO were randomly allocated to treatment or control groups. The treatment group received oral hygiene instruction and use of a sonic toothbrush, while the control group continued their usual home care with manual brushes. Dental impressions and photographs of all subjects were taken at baseline and every 3 months for a year. The casts and photographs were evaluated by a dental panel to compare the DIGO levels from baseline until the end of the study. After 12 months the control group had significantly more severe DIGO than did the sonic tooth brushing and oral hygiene instruction group (OR=4.5, 95%CI=1.2-16.0, P=0.03). Of the risk factors considered, only male gender was significantly associated with worse outcome (OR=6.1, 95%CI=2.3-16.1, P=0.03). The use of a powered toothbrush, together with oral hygiene instruction, may be an important component of health maintenance for pediatric transplant patients on CSA.

Abstract
BACKGROUND Some reports suggest that the prevalence and severity of gingival overgrowth (GO) is lower in patients taking tacrolimus (Tcr) than in those taking cyclosporin A (CsA). The present study was conducted to determine the prevalence and severity of GO in a group of renal transplant recipients treated with Tcr in comparison to those treated with CsA and to evaluate the risk variables associated with the development of GO in these two drug regimens. METHODS A cross-sectional study was conducted in a public hospital in Belo Horizonte City, Brazil. Demographic, pharmacological, and periodontal data were recorded for each subject. Variables from 134 subjects taking Tcr were compared to 451 subjects taking CsA using independent sample t, chi(2) statistic, or Mann-Whitney tests. The effects of potential risk factors on GO severity were determined using forward and backward stepwise regression analysis. RESULTS Subjects taking CsA showed a higher mean GO score (29.03% +/- 22.9%) compared to subjects taking Tcr (16.9% +/- 3.4%) (P = 0.0038). In the Tcr group, 17.9% of the subjects had clinically significant GO compared to 38.1% in the CsA group (P = 0.045). In the multivariate final model, papillary bleeding index, azathioprine dosage, and concomitant use of calcium channel blockers (CCB) were significant variables associated with severity of GO in Tcr and CsA groups. In addition, previous CsA use also remained significant for GO in subjects under a Tcr regimen. CONCLUSIONS The prevalence and severity of GO is lower in transplant subjects taking Tcr compared to CsA. GO severity in both groups was strongly associated with the papillary bleeding index, highlighting the role of inflammation in this condition. Concomitant CCB use, azathioprine dosage, and previous CsA use in the Tcr group reinforces the possible synergistic effects of these pharmacological variables on GO severity.

Abstract
AIM Describe the oral condition of chronic renal failure and healthy subjects, and the relationship between oral variables, chronic renal failure (CRF) conditions, and their treatment. MATERIALS AND METHODS Four renal failure groups: chronic renal disease (n=22); undergoing dialysis (n=22); after dialysis and transplant (n=21); and after transplant (n=32), and a healthy control (n=38) were examined. Caries, enamel hypoplasia, pulp obliteration, plaque index, gingival bleeding, recession, overgrowth and index, probing depths, attachment loss, renal treatments and their relations with the oral variables were analysed. RESULTS The renal failure groups had higher gingival index (GI) and bleeding, probing depths, attachment loss, hypoplasia and obliteration and less caries, than the control. Plaque was higher in the dialysis and pre-dialysis (PD) groups. Overgrowth was evident after transplant. The PD group showed lower GI than other renal groups. Dialysis duration and end-stage renal failure significantly correlated with gingivitis, probing depth, attachment loss and enamel hypoplasia. Immuran correlated positively with probing depth, gingival recession and attachment loss. Normiten and Nifedipine had positive correlations with gingival overgrowth. CONCLUSIONS CRF patients are characterized by pulp obliteration, gingival and periodontal diseases. Duration of end stage renal failure and type of systemic treatment have a significant influence on the oral condition.

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
OBJECTIVES This study investigates the effect of a range of potential risk factors on the severity of gingival overgrowth in transplant patients medicated with ciclosporin in the absence of any calcium channel blockers. MATERIALS AND METHODS One hundred dentate solid organ transplants medicated with ciclosporin (but not calcium channel blockers or phenytoin) were recruited for the study. Demographic, pharmacological and periodontal data were recorded and gingival overgrowth assessed from stone models. RESULTS Univariate analysis identified the duration of transplant, papilla bleeding index, creatinine serum concentration, azathioprine and prednisolone dosage as risk factors for overgrowth severity. Multivariate modelling, excluding the periodontal parameters, gave a predictive model that included dosages of ciclosporin, azathioprine, prednisolone and weight (p<0.0001, adjusted-R2=19%). Adding the periodontal variables strengthened the model (p<0.0001, adjusted-R2=34.5%). CONCLUSION The explanatory models in this study contain a number of variables that moderate inflammation (azathioprine and prednisolone) or are markers of it (papilla bleeding index). Dosage of each of the three immunosuppressants was identified as a risk factor for the severity of gingival change. This observation appears to have been masked by the effects of the calcium channel blockers in earlier studies.

Abstract
OBJECTIVE To determine whether there is association between genotypes of drug transporter multidrug resistant (MDR)1 gene coding drug transporter P-glycoprotein and gingival overgrowth in kidney transplant patients. METHODS Fifty-four unrelated kidney transplant patients suffering from gingival overgrowth as well 120 control transplant patients without overgrowth were enrolled into the study. Gingival overgrowth was assessed by two independent periodontal specialists at 6 months after transplantation. During the post-transplant period all patients were given medication, which included cyclosporine A, diltiazem or verapamil, prednisone, azathioprine. MDR1 C3435T polymorphism was determined using the polymerase chain reaction-restriction fragment length polymorphism assay. RESULTS In kidney transplant patients suffering from gingival overgrowth mean score of gingival overgrowth was 1.43 +/- 0.63, whereas in control subjects was 0.0. Patients with gingival overgrowth induced by immunosuppressive medication were characterized by similar distribution of MDR1 genotypes. There were no significant differences of 3435CC, 20.4% and 22.5%, 3435CT, 61.1% and 54.2% and 3435TT, 18.5% and 23.3% genotypes (frequencies) between patients with and without gingival overgrowth. The risk of gingival overgrowth was the highest among patients carrying 3435CT genotype (OD 1.33), but did not differ markedly from the other genotypes, i.e. 3435CC (OD 0.88) and 3435TT (OD 0.75). Likewise to genotypes, distribution of alleles was similar in patients with gingival overgrowth and healthy gingiva. The wild-type allele 3435C was found in 50.9% and 49.6% of subjects whereas the mutated allele 3435T was revealed in 49.1% and 50.4% of patients with and without gingival overgrowth, respectively. The evaluated risk of gingival overgrowth in patients with 3435C allele was 1.06 versus 0.95 in those with healthy gingiva. The medication regimen administered in both groups of the study was comparable. Immunohistochemical studies revealed expression of P-glycoprotein in ducts of the salivary gland. CONCLUSION No association between the MDR1 gene polymorphism and gingival overgrowth was revealed in kidney transplant patients administered cyclosporine A as a principal immunosuppressive agent. Further studies are needed to elucidate the role of P-glycoprotein in drug transport in salivary glands.

Abstract
AIMS The study aims to determine the prevalence and severity of gingival overgrowth in a group of adult organ transplant recipients immunosuppressed with tacrolimus in comparison with ciclosporin, and to examine various risk factors for the development of gingival overgrowth. METHODS Forty patients taking tacrolimus were compared with 197 ciclosporin patients. Demographic, pharmacological and periodontal data were recorded for all patients. Comparison between the groups was made using independent sample t-tests, chi2 statistic or Mann-Whitney test. The effects of risk variables on overgrowth severity were examined using forward and backward stepwise regression analysis. RESULTS Those taking tacrolimus had a significantly lower mean gingival overgrowth score (14.1%) compared with ciclosporin (22.4%). Fifteen percent of the tacrolimus group had clinically significant gingival overgrowth compared with 30% in the ciclosporin group (p=0.053). CONCLUSIONS The prevalence and severity of gingival overgrowth is less in adult transplant patients taking tacrolimus compared with ciclosporin. Concomitant use of calcium channel blockers and previous medication with ciclosporin are significant risk factors for the presence and severity of gingival overgrowth. Patients who have alteration of their immunosuppressant from ciclosporin to tacrolimus may persist in demonstrating gingival overgrowth attributable to their ongoing therapy with calcium channel blockers.

Abstract
BACKGROUND The incidence of gingival overgrowth (GO) associated with the use of cyclosporin A (CsA) is controversial. In the present study, we determined the incidence of GO in Brazilian renal transplant patients treated with CsA and the possible associations between periodontal and pharmacological variables. METHODS The test group consisted of 20 renal transplant patients, and the control group included 20 non-transplant patients. Periodontal conditions were evaluated based on the plaque index (PI), gingival index (GI), probing depth (PD), and the rate of gingival overgrowth, together with pharmacological variables (daily CsA dose and duration of treatment). RESULTS A significant difference in PI (P < 0.0001) and PD (P < 0.0001) was observed between groups, while GI (P = 0.15) did not differ significantly. Using the Pearson correlation coefficient, a significant correlation was observed not only between GI (P < 0.001; r = 0.8141) and GO, but also for PD (P < 0.001; r = 0.866) and GO. The other correlations were not statistically significant. CONCLUSIONS We conclude that GO induced by CsA may vary according to the individual sensitivity of each patient and may or may not be correlated with other local factors (periodontal variables).

Abstract
OBJECTIVES To investigate the prevalence and severity of gingival overgrowth in a group of renal transplant recipients treated in one centre in Northern Ireland. STUDY DESIGN A consecutive group of patients who had had a renal transplant for at least 6 months and were attending the Renal Unit in Belfast City Hospital took part in the study. These were divided into a group of 84 subjects treated with cyclosporin since their transplant who were compared with a control group of 36 transplant recipients who had never received cyclosporin. Each subject had a periodontal examination and completed a questionnaire. The severity of gingival overgrowth was scored from plaster models. OUTCOME MEASURES Clinically significant gingival overgrowth was equated with a score of > or = 30 using the index developed by Seymour et al (1985). RESULTS 41 (49%) of the cyclosporin group had clinically significant gingival overgrowth compared with none of the controls. A significantly higher proportion of males had overgrowth than females. There were significant correlations between age at transplant, plaque, bleeding, pocketing and the severity of gingival overgrowth. Many patients with clinically significant gingival overgrowth were apparently unconcerned about this condition. CONCLUSIONS It is concluded that gingival overgrowth is a significant problem for renal transplant patients treated with cyclosporin, particularly if they are also treated with a calcium channel blocker. None of the factors measured, in isolation, explained the variable expression of gingival overgrowth in those at risk.
