Prevalence of aggressive periodontitis in adolescents and young adults from Vale do Paraíba

The aim of the present study was to determine the prevalence of localized and generalized aggressive periodontitis, as well as of incidental attachment loss, in a population of adolescents and young adults aging between 15 and 25 years (19.4 ± 3.44) from Vale do Paraíba - SP, who searched for general dental care at the Department of Dentistry, University of Taubaté, São Paulo. Six hundred patients, 244 male and 356 female subjects, were included in the studied sample. The periodontal status of this population was evaluated by measuring the depth of periodontal pockets, as well as attachment loss. The data were confirmed by means of radiographic examination. Measurements were performed in six sites per tooth. Ten subjects (1.66%) were diagnosed as having localized aggressive periodontitis, 2 males (aging 18.5 ± 2.12 years) and 8 females (aging 19.2 ± 3.91 years); 22 (3.66%) presented with generalized aggressive periodontitis, 6 males (aging 19.1 ± 3.06 years) and 16 females (aging 20.1 ± 2.71 years); and 86 individuals (14.3%) presented with incipient periodontitis, 29 males (aging 20.2 ± 2.87 years) and 57 females (aging 21.1 ± 2.79 years). There was a positive correlation between the female gender and the occurrence of periodontal disease.O objetivo do presente estudo foi avaliar a prevalência de periodontite agressiva localizada, periodontite agressiva generalizada e periodontite incipiente em uma população de 15 a 25 anos de idade (19,4 ± 3,44) da região do Vale do Paraíba - SP que procuraram tratamento odontológico clínico geral no Departamento de Odontologia da Universidade de Taubaté, SP.

AVALIAÇÃO DA PERIODONTITE INDUZIDA EM RATOS PREVIAMENTE EXPOSTOS À CICLOSPORINA A: ANÁLISE HISTOLÓGICA E BIOQUÍMICA

A imunossupressão gerada pela ciclosporina A (CsA) tem sido associada à perda óssea alveolar (PO) em modelos animais com doença periodontal induzida (SPOLIDÓRIO et al., 2001, 2004). O objetivo deste estudo foi comparar através de análise histológica e bioquímica, as alterações ósseas na periodontite induzida por ligadura (L) em ratos previamente expostos a CsA. Foram utilizados 36 animais, divididos em 4 grupos (n=9): GC – controle; GCsA; GL ; GCsAL. Doses diárias de 10mg/kg de peso dos animais foram aplicadas em CsA e GsAL por 60 dias. A ligadura foi inserida no primeiro molar inferior 30 dias após o início do experimento em GL e GCsAL. Passados 60 dias, foram coletadas amostras sangüíneas para mensuração da fosfatase alcalina (FA). Em seguida, os animais foram sacrificados e as mandíbulas processadas para análise histológica da área ocupada pelo ligamento periodontal (ALP) e células marcadas pela fosfatase ácida tartarato-resistentes (TRAP+). Os resultados não mostraram diferença estatística significativa (ANOVA, Tukey) nos valores da FA (p=0,1). Após análise de variância os resultados mostraram diferença estatística nos valores da ALP (p=0.03994) e ausência de diferença estatística nos valores de células TRAP+ (p=0.3995). Neste estudo, a presença da CsA não influenciou a PO causada pela periodontite induzida

Horizontal Alveolar Ridge Augmentation in the Mandibular Posterior Region Using Biphasic Calcium Phosphate and Leukocyte- and Platelet rich fibrin (L-PRF): A case report.

In bone defects caused by tooth loss, tissue reconstructions are necessary to enable prosthetic rehabilitation with dental implants. Diverse techniques and materials of different origins are used for this purpose.  Leukocyte- and Platelet-Rich Fibrin (L-PRF) has been used in association with osteoconductive biomaterials in procedures of bone regeneration and for covering grafted areas. The aim of this article was to demonstrate a clinical case of bone grafting in the posterior region of the mandible, performed with the use of synthetic biomaterial composed of biphasic calcium phosphate associated with Leukocyte- and Platelet-Rich Fibrin for performing bone augmentation in an alveolar ridge with a horizontal defect, thereby enabling later installation of dental implants and prosthetic rehabilitation in the region. Keywords: bone graft, biomaterials, leukocyte- and platelet-rich fibrin, bone substitutes, dental implants.In bone defects caused by tooth loss, tissue reconstructions are necessary to enable prosthetic rehabilitation with dental implants.

Periodontal disease in a rural community in Minas Gerais, Brazil

of this study was to evaluate the prevalence and severity of periodontal disease and treatment needs in a Brazilian rural community, using the Community Periodontal Index of Treatment Needs (CPITN). This study included 183 individuals who were clinically evaluated. The results showed that 45% of the individuals between ages 0-5 years had bleeding upon probing, and 34% of individuals ages 6-12 presented dental calculus. Among the individuals ages 13-18, 15% of pathological pockets were found with probing depth (PD) of 4-5 mm. However, among individuals ages 19-34, 50% showed a PD of 4-5 mm and 12.5% PD ≥ 6 mm. In the group of individuals ages 35-44, 17% showed PD ≥ 6 mm. Ninety percent of the individuals up to 13 years old needed only oral hygiene instructions. Dental scaling was indicated to 70% and 95% of the individuals aged 13-18 and 19-34 respectively. A more complex periodontal therapy was indicated to 17% of individuals aged 35-44. These results showed the necessity of the implementation of dental preventive programs to this community, especially to individuals under 12 years, and curative programs for individuals ages older than 13 years old

Menopausa: fator de risco para doença periodontal?

OBJETIVO: verificar se existe relação entre os parâmetros periodontais e os níveis de estrógeno e densitometria óssea mineral (DOM). MÉTODOS: foram avaliadas 46 mulheres na pós-menopausa entre 44 e 68 anos de idade (52,2±4,8) e 15 mulheres como grupo controle entre 35 e 54 anos de idade (44,7±7,5). Parâmetros periodontais como profundidade à sondagem (PS), perda de inserção clínica (PIC) e dentes ausentes (DA) foram comparados com os níveis de estrógeno (suficiente e deficiente) e DOM em normais, osteopênicas e osteoporóticas. Os dados foram comparados pela diferença das médias entre os grupos e analisados pelo teste de Aspin-Welch. RESULTADOS: as médias dos parâmetros de PS, PIC e DA, quando associados ao grau da DOM em normais (2,1±0,5; 2,9±1,4 e 10,6±5,0), osteopênicas (2,3±0,7; 3,0±1,1 e 12,8±5,1) e osteoporóticas (2,4±0,6; 2,7±0,9 e 14,3±5,7), não mostraram diferenças significativas (p>0,05). Foi encontrada diferença significante entre o grupo controle e nas mulheres menopausadas para PIC e DA. Quando comparados com os níveis de estrógeno os resultados demonstraram igualdade para os parâmetros periodontais. CONCLUSÕES: apesar de alguns estudos demonstrarem correlação positiva da doença periodontal com osteoporose e com os níveis de estrogênio, na população de mulheres menopausadas estes dados não foram confirmados neste estudo

Periodontal clinical evaluation before and after surgically assisted rapid maxillary expansion

ABSTRACT Introduction: The surgically assisted rapid maxillary expansion is a procedure that reduces the resistance of the sutures correcting the posterior crossbite in adults. Objective: The aim of this study was to evaluate the periodontal status of 17 adults submitted to this procedure. Methods: The clinical attachment level (CAL), gingival recession, attached gingiva and bleeding were evaluated in maxillary first premolars and molars, central and lateral incisors of right and left sides before surgery, 5 days and 6 months after. Means, standard deviation, medians, minimum and maximum values were compared among the evaluations using the Friedman and McNemar tests. Results: There was a statistically significant increase in CAL in the right central incisor, right and left premolars and right and left molars. There was a statistically significant increase in gingival recession in the right and left premolars and molars. The amount of attached gingiva significantly decreased in right premolars and right and left molars. There was increase in bleeding in most of the teeth. Conclusion: Results indicated that the surgically assisted rapid maxillary expansion might cause alterations in periodontal tissue
