A retrospective analysis of oral and maxillofacial pathology in a pediatric population from Rio de Janeiro-Brazil over a 75-year period

BACKGROUND: The aim of this study was to analyze the distribution of oral and maxillofacial lesions affecting children and adolescents patients from a single oral pathology laboratory from Rio de Janeiro, Brazil. MATERIAL AND METHODS: Oral and maxillofacial lesions biopsied in patients younger than 19-years were retrieved from the oral pathology files of the Department of Oral Diagnosis and Pathology, School of Dentistry, Federal University of Rio de Janeiro over a 75-year period (1942-2017). The clinical data and the diagnoses of each case were included in a Microsoft Excel(R) database, being classified into 13 categories according to the etiology. A descriptive analysis of the variables age, gender and final diagnosis was made. RESULTS: From 19.095 lesions diagnosed in this period, 2408 (12.61%) were from patients aged 0 to19 years, with a higher incidence in females in the second decade. Salivary gland pathology was the most common group of lesions (24.30%), followed by reactive lesions (16.82%) and odontogenic cysts (14.66%). Mucocele was the most common lesion (21.72%), followed by dentigerous cyst (6.48%) and fibrous hyperplasia (6.44%). Malignant lesions were observed in 1.12% of all cases with Burkitt lymphoma as the most frequent. CONCLUSIONS: Our results were similar to previous studies and knowledge of these data may contribute to the understanding of oral lesions that most commonly affects children

Distribution of biopsied non plaque-induced gingival lesions in a Chilean population according to the classification of periodontal diseases.

BACKGROUND: Many gingival lesions are not induced by plaque. The aim of this study was to analyze the frequency of biopsied non-plaque-induced gingival lesions (NPIGL) in a Chilean population. METHODS: One thousand twelve cases of biopsied gingival lesions with confirmed anatomopathologic diagnosis were included, from the records of the Oral Pathology Referral Institute (OPRI), Faculty of Dentistry, University of Chile, between years 1990 and 2009. RESULTS: The most frequent non plaque-induced gingival lesions categories from biopsied cases included hyperplastic lesions, malignancies and benign neoplasms. The most frequent diagnoses in each category were fibrous hyperplasia (35.47%), squamous cell carcinoma (3.85%) and giant cell fibroma (2.08%), respectively. From all lesions, only 8.3% fitted in the specified categories of the current classification of periodontal diseases. CONCLUSIONS: The most frequent biopsied NPIGL were hyperplastic lesions and neoplasms. These categories represent relevant lesions to be included in a future periodontal classification system to improve the care needs of the patients, as well as early diagnosis and treatment.

Part 3: Impact of systemic conditions and medications on oral health.

The people who are treated in the community setting will often have multiple comorbidities. Systemic medical conditions can have a negative impact on oral health. In addition, the medications used to treat systemic conditions may also themselves cause oral symptoms. As a large proportion of patients treated by the community nursing team will be elderly, this paper will focus on common geriatric conditions that can display oral or dental symptoms. The effects of medications will be discussed and linked to oral complaints patients may express. The primary aims are to give a broad overview of the oral effects of ageing, of illness and of polypharmacy and advise on how these can be best managed by the nursing team.

Distribution of oral and maxillofacial lesions in pediatric patients from a Brazilian southeastern population.

OBJECTIVES: Oral lesions affecting infants account for approximately 10% of all samples from diagnostic services and studies investigating the distribution of these lesions in pediatrics from different geographic areas are desired to improve the diagnostic knowledge of clinicians. Therefore, the aim of this study is to describe the distribution of oral lesions in a southeastern Brazilian population. METHODS: The oral pathology files of the University of Campinas was retrospectively reviewed for all cases diagnosed from 2000 to 2014 affecting patients 16-years-old and younger. Data on gender and diagnosis were retrieved from patients' oral pathology reports and included in a Microsoft Excel® database. RESULTS: Out of 34,138 cases, 2539 affected pediatric patients (7.4%) with a higher incidence in those with 13-16 years-old. Salivary gland disease was the most common group of lesions (37.1%), followed by mucosal pathology (13.6%) and odontogenic cysts (11.3%). Mucous extravasation cyst was the most common lesion (36.3%), followed by fibrous hyperplasia (5.6%) and dental follicle (5.2%). Dental lesions were uncommon (7.9%) and malignancies rare (0.4%). CONCLUSIONS: Our results were similar to previous studies and the small differences observed were more likely result of methodological variability and characteristics of the service of origin from where samples were collected.

Impacto de lesiones orales sobre la calidad de vida en pacientes adultos / Impact of oral injuries on the quality of life in patients

Objetivo: Evaluar el impacto de lesiones orales sobre la calidad de vida relacionada con la Salud Oral (CVRSB) en adultos. Materiales y métodos: Estudio analítico transversal, muestra a conveniencia de 292 pacientes, Facultad de Odontología, Universidad de Cartagena, con lesiones orales en los últimos 3 meses y diligenciaron el Índice de Salud Oral General, GOHAI para evaluar CVRSB. Dos examinadores fueron calibrados para evaluar lesiones orales. Fue realizado análisis univariado y multivariado de Regresión de Poisson con varianza robusta y nivel de confianza del 95%. Resultados: 39% (IC 95%: 33-44) de los pacientes presentaron un alto impacto de la CVRSO; 28,7 (DE: 0,45), fue la media del puntaje total GOHAI. La mayoría de las lesiones encontradas fueron lesiones secundarias deprimidas asociadas a dolor (aftas= 24,6%). Casi todas las lesiones orales se asociaron con los puntajes totales GOHAI en el análisis univariado (p<0,05). El modelo final multivariado quedó ajustado así: las úlceras orales presentaron un impacto negativo sobre CVRSO (RR= 1,2, IC 95%:1,1-1,3, p= 0,000), igual que la hiperplasia gingival (RR= 1,2, IC 95%: 1,03-1,4, p= 0,02) y el herpes labial (RR= 1,2, IC 95%: 1,02-1,4, p= 0,02), a diferencia del torus palatino (RR= 0,85, IC 95%:0,7-0,9, p= 0,001), mientras tener trabajo presenta un impacto positivo (RR= 0,91, IC 95%: 0,86-0,97, p= 0,007). El dominio psicosocial fue el más comprometido. Conclusiones: La úlceras orales, hiperplasia gingival y herpes labial presentan un impacto negativo sobre la CVRSO, a diferencia del torus palatino, mientras que el tener trabajo presenta un impacto positivo (AU)

Objective: Assess the impact of oral lesions on the quality of life related to Oral Health (QLROH) in adults. Materials and methods: Transversal analytical study, a convenience sample of 292 patients, Faculty of Dentistry, University of Cartagena, with oral lesions in the last three months and administered the Oral Health Index General, GOHAI to evaluate QLROH. Two examiners were calibrated to evaluate oral lesions. It was conducted univariate and multivariate Poisson regression with robust variance and confidence level of 95%. Results: 39% (95% CI: 33-44) of patients had a high impact of QLROH; 28,7 (SD: 0,45) was the mean total score GOHAI. Most of the injuries found were depressed secondary lesions associated with pain (aphtha= 24,6%). Almost all oral lesions were associated with total scores GOHAI in univariate analysis (p<0.05). The final multivariate model was adjusted as follows: oral ulcers had a negative impact on QLROH (RR= 1,2, 95% CI: 1,1-1,3, p= 0,000), gingival hyperplasia (RR= 1,2, 95% CI: 1,03-1,4, p= 0,02) and herpes labialis (RR= 1,2, 95% CI:1,02-1,4, p= 0,02) unlike the palatal torus (RR= 0,85, 95% CI: 0,7-0,9, p= 0,001), while having a job has a positive impact (RR= 0,91, 95% CI: 0, 86-0,97, p= 0,007). The psychosocial do main was the most compromised. Conclusions: The oral ulcers, gingival hyperplasia and herpes labialis have a negative impact on QLROH, unlike the palatal torus, while having a job has a positive impact (AU)

A retrospective analysis of reactive hyperplastic lesions of the oral cavity: study of 1149 cases diagnosed between 2000 and 2011, Chile / Análisis retrospectivo de lesiones reaccionales hiperplásicas en mucosa oral: estudio de 1149 casos diagnosticados entre el 2000–2011 en chile

El objetivo de este estudio fue determinar la frecuencia relativa y distribución de lesiones reaccionales hiperplásicas (LRH) de la mucosa oral, presentes en el registro de biopsias del Servicio de Anatomía Patológica de la Facultad de Odontología, Universidad de Chile. Este estudio de tipo retrospectivo consistió en 1149 biopsias con diagnóstico histopatológico de LRH, entre los años 2000-2011. Las LRH se clasificaron en 5 grupos: Hiperplasia fibrosa (HF), granuloma piogénico (GP), granuloma periférico de células gigantes (GPCG) y fibroma osificante periférico(FOP). Los datos de edad y sexo de los sujetos, y de localización y tipo de lesión, fueron obtenidos del registro de biopsias de cada caso. De las LRH, la lesión más frecuente fue HF (71,1 por ciento), seguido de GP (21,1 por ciento), GPCG (5 por ciento) y FOP (2,9 por ciento) respectivamente. Las biopsias de LRH fueron mas frecuentes en mujeres (70,7 por ciento). El rango etario más afectado fue el de 50 a 59 años (22 por ciento). La localización de mayor frecuencia de LRH fue el maxilar superior (24,7 por ciento), seguida de mejilla (20,6 por ciento), lengua (19,4 por ciento), mandíbula (18,5 por ciento), labio inferior (9,9 por ciento) y labio superior (6,7 por ciento). En este estudio, de las LRH el diagnóstico más prevalente fue FH. El sexo más afectado fue el femenino, el rango etario el de 50 a 59 años y la ubicación más frecuente, maxilar superior. Estos resultados en general son concordantes con lo descrito en otros países.

The aim of this study was to determine the relative frequency and distribution of reactive hyperplastic lesions (RHL) of the oral mucosa at the Oral Pathology Institute of the School of Dentistry at the University of Chile. This was a retrospective study of 1149 biopsies with histopathological diagnosis of RHL, performed between 2000 and 2011. The RHL were classified in 4 groups: fibrous hyperplasia (FH), pyogenic granuloma (PG), peripheral giant-cell granuloma (PGCG) and peripheral ossifying fibroma (POF). Results: the most frequent RHL was FH (71. 1%), followed by PG (21.1%), PGCG (5 %) and POF (2.9%). RHLs were more frequent in women (70.7%). The most highly affected age group was the 50- to 59-year-olds (22%). The most frequent location for RHL was maxilla (24.7%), followed by cheek (20.6%), tongue (19.4%) and jaw (18.5%). The most prevalent RHL diagnosis was FH. Themost frequently affected sex was female, the most frequent agerange was 50-59 years, and the most frequent location, maxilla.

A retrospective analysis of oral and maxillofacial pathology in an Australian adult population.

BACKGROUND: The prevalence of oral and maxillofacial pathology has not previously been reported in the Australian adult population. This study aimed to audit a large pathology service to provide insight into the prevalence of head and neck pathologies. METHODS: Written records of a major Australian oral pathology service were imported into an electronic database. Age, gender and histological diagnosis were assessed. Prevalence of histological diagnoses as a percentage of the major diagnostic categories and of the whole sample were calculated, as well as gender predilections and mean age of presentation of disease. RESULTS: A total of 6344 oral pathology specimens, collected from adults aged 17 years and over were included in the analysis. Mucosal pathology was the most common pathology (37.2%), followed by odontogenic cysts (16.3%) and dental pathology (14.5%). The three most common histological diagnoses were fibrous hyperplasia (15.2%), chronic periapical granuloma (9.6%) and radicular cyst (9.5%). The male:female ratio of the entire sample was 0.74. CONCLUSIONS: This is the first study to describe the prevalence of oral and maxillofacial pathology among adult patients in an Australian population. The trends seen in this study are repeated in studies from other parts of the world, and are of diagnostic importance.

A retrospective analysis of oral and maxillofacial pathology in an Australian paediatric population.

BACKGROUND: The prevalence of oral and maxillofacial pathology has not previously been reported in the Australian paediatric population. This study aimed to audit a large pathology service to provide insight into the prevalence of oral and maxillofacial pathology. METHODS: Written records of a major Australian oral pathology service were imported into an electronic database. Age, gender and histological diagnosis were assessed. Prevalence of histological diagnoses as a percentage of the major diagnostic categories and of the whole sample were calculated, as well as gender predilections and mean age of presentation of disease. RESULTS: A total of 1305 oral pathology specimens, collected from paediatric patients aged 16 and under were included in the analysis. The most common pathology was dental pathology (24.4%), followed by odontogenic cysts (18.5%) and mucosal pathology (17.0%). The most frequently encountered lesion was the dentigerous cyst (9.4%), followed by fibrous hyperplasia (8.3%), radicular cyst (5.2%) and chronic periapical granuloma (5.2%). CONCLUSIONS: In the paediatric population, dental pathology and specifically, the dentigerous cyst is the most common pathology type sent for histopathology, suggesting a high prevalence of pathology of dental origin occurring in Australian children.

Oral manifestations of allograft recipients before and after renal transplantation.

Renal transplantation is considered the best treatment option for patients with end-stage renal disease. In this study, the prevalence of oral lesions was studied in a cohort of renal transplant recipients before and after transplantation. Fifty-nine kidney transplant recipients were examined one week before and four months after transplantation. The information gathered included age, sex, smoking history, duration on dialysis, drugs and their doses. There were 41 males (69.5%) and 18 females (30.5%) with a mean age of 37 years. Before surgery, two patients had non-specific lesions and two other patients had leukoedema. Following transplantation, 24 patients (40.7%) did not have any specific lesion. In six patients, we observed non-specific erythematous lesions (10.2%). Other recorded observations are as follows: Gingival hyperplasia in five patients (8.5%), oral candidiasis of the erythematous type in five patients (8.5%), hairy leukoplakia in four patients (6.8%) and leukoedema in seven patients (11.9%). In our study patients, the prevalence of oral lesions increased after transplantation, although it was lower than that reported in other studies. This could be due to the differences in sample size, differences between Iranian race and other races and different pharmaceutical formulation of the drug produced in Iran.

[A woman with gingival hyperplasia]. / Een vrouw met gingivahyperplasie.

A woman visited her dentist with complaints of swollen gums. If there was a serious infection of multiple teeth, the surgeon had to do a total extraction of the upper jaw. The clinical picture was suspicious for a lymphoma, a fibromatosis or a gingivitis. The biopsy showed a chronical infection. In this case the gingival overgrowth and the subsequent infection of the teeth were caused by nifedipine. Gingival enlargement can be a consequence of the administration of calcium channel blockers and can occur if these are administered during a few months or years. The incidence is 0,01-0,1% and the prevalence is 20%. Drug substitution should be considered a valid treatment option and can be successful within a few weeks.

The role of MDR1 C3435T gene polymorphism on gingival hyperplasia in Turkish renal transplant patients treated with cyclosporine in the absence of calcium channel blockers.

OBJECTIVE: To investigate the occurrence of MDR1 C3435T gene polymorphisms in the Turkish renal transplant patients treated with cyclosporine (CsA), and correlate these findings with prevalence and degree of gingival hyperplasia (GH). METHODS: Before to renal transplantation, dental treatment and oral hygiene education of 300 renal disease patients was completed. Peripheral blood samples were collected from 154 renal transplant recipients on CsA treatment without calcium channel blockers. MDR1 C3435T gene polymorphism and GH were analyzed at posttransplant month 6. RESULTS: No difference was detected among groups for age, posttransplant period, creatine levels, serum concentration of CsA, or plaque and bleeding indices (P > .05). Out of all transplanted patients, 42.8% were found to have the heterozygote genotype. This was reduced to 37.5% when individuals with GH were taken into account. However, when degree of GH was analyzed, those with severe GH were found to have the heterozygote genotype significantly more often (P < .05). CONCLUSIONS: The MDR1 gene polymorphism is not associated with GH frequency, but may be associated with GH severity.

Relative frequency of localized reactive hyperplastic lesions of the gingiva: a retrospective study of 1675 cases from Israel.

BACKGROUND: The gingiva reacts to chronic irritation or trauma with localized reactive hyperplastic lesions (LRHL) that can be classified into four groups: focal fibrous hyperplasia (FFH), pyogenic granuloma (PG), peripheral ossifying fibroma (POF), and peripheral giant cell granuloma (PGCG). This study determined the frequency of LRHL in an oral pathology biopsy service and compared these data with reports from other countries. METHODS: The material included the biopsies of all consecutive LRHL of the gingiva stored in the departmental database (1989-2008). Lesions were analyzed according to their location and to the patients' age and gender. The findings were compared with those published in studies from other countries. RESULTS: There were 1675 LRHL that comprised 6.7% of the 25,106 accessed biopsies. FFH was the most common (31.8%), followed by PG (29.1%), POF (20.4%), and PGCG (18.7%). POF tended to affect younger patients than did FFH, PG, and PGCG. FFH, PG, and POF were more common in women, while PGCG showed no gender predilection. PG and POF were more common in the maxilla, PGCG more common in the mandible and FFH was distributed equally between the jaws. The anterior region of the maxilla was the most prevalent site for FFH, PG, and POF. CONCLUSION: The results of this study differ somewhat from those of other countries. There is a need for further investigation to answer the question whether the differences can be attributed to geographic or ethnic factors and/or to small sample sizes of the reported studies.

Pediatric localized reactive gingival lesions: a retrospective study from Israel.

PURPOSE: Chronic irritation of the gingiva causes localized reactive hyperplastic lesions (LRHLs), which are classified into: peripheral ossifying fibroma (POF); peripheral giant cell granuloma (PGCG); pyogenic granuloma (PG); and focal fibrous hyperplasia (FFH). The purpose of this study was to determine the frequency of localized reactive hyperplastic lesions in Israeli children and adolescents. METHODS: All consecutive archival LRHL biopsies of the gingiva between 1989 and 2008 were included. Lesions were analyzed according to location and patients' age and gender. Our findings were compared to pediatric and all-age data in publications from other countries. RESULTS: Of 233 gingival LRHL specimens, POFs were most common (33%), followed by PGs (25%), FFHs (23%) and PGCGs (20%). PGs and FFHs were more common in females, and PGCG were more common in males. POFs showed no gender predilection. PGCGs and FFHs were distributed almost equally between the maxilla and mandible, while POFs and PGs were more common in the maxilla. Comparing data to other countries was problematic because there were so few dedicated to the pediatric population and because of inconsistencies in data presentation. CONCLUSIONS: Pediatric dentists should be aware of gingival LRHLs, because they are not uncommon among children.

Denture-related hyperplasia: a clinical study of a Turkish population group.

Inflammatory fibrous hyperplasia (epulis fissuratum) (IFH) and inflammatory papillary hyperplasia (IPH) are oral mucosal diseases caused by ill-fitting denture wearing. A study was carried out on a group of Turkish people consisted of 131 female and 39 male complete denture wearers (n= 170) distributed in two age groups (30-60 and 60-80 years old). The analysis of data collected from patients showed that while the incidence of IFH was higher in women than in men, the incidence of IPH was similar. Most lesions were found in the 30-60 year-old group. The incidence of lesions increased as the denture wearing period increased. Soft tissue growth was the main complaint of the patients with IFH and IPH. In the maxilla, the incidence of IFH was higher than IPH. There was also a significant difference between the distribution of the lesion types in the jaws. There were a larger number of lesions in the maxilla compared to the mandible and most IFH lesions were located in the anterior region of the jaws.

Poor oral hygiene enhances gingival overgrowth caused by calcineurin inhibitors.

AIM: To estimate the prevalence of gingival overgrowth in kidney allograft recipients in southern Switzerland and to determine the factors associated with it. We hypothesized that poor oral hygiene was a risk factor. METHODS: We assessed the level of oral hygiene among renal transplant patients and determined whether a good level of information and regular dental checkups in addition to good oral hygiene could prevent gingival hyperplasia. Seventy-six adults who had undergone kidney transplantation were examined. The level of oral hygiene, gender, age, time elapsed from transplantation, medication and dose were recorded. RESULTS: In general the level of oral hygiene was average. We found a significant association between the severity of gingival overgrowth and the level of oral hygiene. No statistical relationship between gingival hyperplasia and the other recorded variables was detected. Patients on tacrolimus had a tendency to have less gingival hyperplasia. Patient education, along with regular dental checkups and a good level of oral hygiene, should prevent gingival hyperplasia or maintain it at an acceptable level. CONCLUSION: Intensive motivation of patients to maintain good oral hygiene is necessary to reduce the incidence of gingival hyperplasia.

Estudo clínico-patológico do carcinoma epidermóide de língua e imunohistoquímico das proteínas bmp-2, bmpr-ia, bmpr-ii e endoglina / Physician-pathological study of the carcinoma epidermóide of language and imunohistoquímico of proteins bmp-2, bmpr-went, bmpr-ii and endoglina

As BMPs (proteinas morfogenéticas ósseas) são citocinas relacionadas com a proliferação e angiogênese em diversos tipos de câncer humano. Com este trabalho foi analisada a expressão imunohistoquímica das proteínas NMP-2, BMPR-IA, BMPR-II e endoglina (CD105), correlacionando-a com o comportamento biológico e a angiogênese local nos carcinomas epidermóides de língua (CEL). A amostra foi composta de 25 casos de CEL sem metástase (CELSM), 25 CEL com metástase (CELCM) graduados segundo Bryne (1198) e adaptado por Miranda (2002), além de 25 casos de hiperplasia fibrosa inflamatória (HFI), utilizado como grupo controle. Foi utilizado escore 0 para marcação ausente-fraca e 1 para forte; tipo de distribuição focal ou difuso. Adicionalmente, para o CD105 foi realizada a contagem microvascular (MVC). A maior parte dos pacientes com CEL foi do sexo masculino, no grupo CELSM a faixa etária foi maior que 65 anos e o CELCM se encontrou entre 45-65 anos; houve predomínio do estágio II do TNM, assim como de...

Gingival enlargement in antihypertensive medication.

INTRODUCTION: Drug-induced gingival enlargement is a well documented side effect with the use of phenytoin, cyclosporine and calcium channel blockers. The prevalence of gingival enlargement induced by calcium channel blockers is uncertain. Several studies show conflicting results ranging from 20% to 83%. This study was conducted to determine the prevalence of gingival enlargement in patients taking antihypertensive medication. METHODS: All consecutive patients on antihypertensive agents attending the Dental OPD were studied. The prevalence of drug induced gingival enlargement was determined. The periodontal condition of all subjects were assessed including plaque index and probing depth. RESULTS: Total 81.2% of subjects taking antihypertensive were seen to have significant enlargement. Among them 71.1% were taking calcium channel blocker, 21.5% were taking ACE Inhibitors, and 7.4% were taking beta-blockers. CONCLUSIONS: Patients taking antihypertensive agents are at increased risk for gingival enlargement and inflammation is an important cofactor for the expression of this effect.

Oral disease burden and utilization of dental care patterns among pediatric solid organ transplant recipients.

OBJECTIVES: We conducted a study among pediatric renal (RTRs) and liver transplant recipients (LTRs) to determine: a) the overall burden of oral disease; and b) the frequency with which this population utilizes dental care services in relation to sociodemographic factors and oral disease burden. METHODS: In this cross-sectional survey, study procedures included the completion of a standardized questionnaire (by parents/guardians), oral mucosal examination, assessment of caries, gingival enlargement, and plaque index. RESULTS: The 142 children (82 RTRs and 60 LTRs) enrolled from April 2002 to November 2005 were predominantly Latino (41 percent) and Caucasian (34 percent). Forty-three percent had at least one carious surface (in either a deciduous or permanent tooth), 19 percent had five or more carious surfaces, and 25 percent had gingival enlargement. We found only one case of oral candidiasis. Even though 72 percent of parents/guardians reported their child had a regular source of dental care, only 49 percent had a dental cleaning and 44 percent had dental radiographs in the past year, reflecting a low prevalence of preventive dental care. Among children with no regular source of dental care, there were statistically significantly higher proportions of Latinos, younger children, and families with an annual household income <$35,000. CONCLUSION: While the prevalence of oral mucosal disease and gingival enlargement was low, the prevalence of children with caries was high, and there was low use of preventive dental care. Strategies to improve this population's utilization of preventive dental care are needed.

Denture-related hyperplasia: a clinical study of a turkish population group

Inflammatory fibrous hyperplasia (epulis fissuratum) (IFH) and inflammatory papillary hyperplasia (IPH) are oral mucosal diseases caused by ill-fitting denture wearing. A study was carried out on a group of Turkish people consisted of 131 female and 39 male complete denture wearers (n= 170) distributed in two age groups (30-60 and 60-80 years old). The analysis of data collected from patients showed that while the incidence of IFH was higher in women than in men, the incidence of IPH was similar. Most lesions were found in the 30-60 year-old group. The incidence of lesions increased as the denture wearing period increased. Soft tissue growth was the main complaint of the patients with IFH and IPH. In the maxilla, the incidence of IFH was higher than IPH. There was also a significant difference between the distribution of the lesion types in the jaws. There were a larger number of lesions in the maxilla compared to the mandible and most IFH lesions were located in the anterior region of the jaws.

A hiperplasia fibrosa inflamatória (epulis fissuratum) (HFI) e a hiperplasia papilar inflamatória (HPI) são doenças da mucosa causadas por próteses mal-ajustadas. Foi feito um estudo num grupo de pessoas, na Turquia, composto por 131 mulheres e 39 homens (n=170) usuários de próteses totais. O grupo foi subdividido em duas faixas etárias (30 a 60 e 60 a 80 anos). A análise dos dados coletados dos pacientes mostrou que a incidência de HFI foi mais alta entre as mulheres, ao passo que a incidência de HPI foi similar em ambos os sexos. A maioria das lesões foi encontrada no grupo indivíduos de 30 a 60 anos. A incidência das lesões aumentou com o tempo de uso da prótese. A queixa principal dos pacientes com HFI e HPI foi o aparecimento de tecidos moles. A incidência de HFI foi maior do que HPI, na maxila. Houve também diferença significativa de distribuição dos tipos de lesão nos maxilares. Houve maior número de lesões na maxila, em comparação com a mandíbula e a maioria das lesões HFI estava localizada na parte anterior dos maxilares.

Gingival overgrowth in renal transplant recipients: a study concerning prevalence, severity, periodontal, and predisposing factors.

Gingival overgrowth (GO) is the main oral manifestation in transplant recipients who use calcineurin inhibitors. In the present study, factors for GO development were investigated in Brazilian renal transplant recipients who were prescribed cyclosporine (CsA) or tacrolimus (TAC). Demographic, pharmacological, clinical, and periodontal data were obtained from 83 patients, as well as HLA expression in 51 of them. The prevalence of GO was high (47%), but its severity was low according to periodontal indices. The prevalence of GO was greater among patients who used CsA (n = 49) than those receiving used TAC (n = 34) namely, 61% versus 26.5% (P = .003). Comparisons between patients with versus without GO were performed independent of the administered immunossupressant. The group with GO showed a greater degree of gingival inflammation index. HLA-A68 had greater expression among patients without GO (P = .04). The risk factors for GO occurrence were evaluated using a multivariate analysis that identified gingival inflammation and HLA-A24 expression as risk factors. Increased age and use of TAC were identified as protective factors. GO showed a high prevalence, yet a light intensity. Patients who were younger, men, or received CsA showed a greater occurrence of GO. The risk factors identified for GO development were the presence of gingival inflammation and HLA-A24 expression.
