Avaliação da redução do índice de placa visível e do índice de sangramento gengival em uma prática de promoção de saúde bucal com crianças

The purpose of this research was to evaluate the reduction of the VPI (visible plaque index) and of the GBI (gum bleeding index) in children seen at a unit of SUS, in the state of Rio de Janeiro. A comparative and statistical procedure (t-test, by means of the GMC program) was employed in order to assess the variation between initial and final mean VPI and GBI values. Initial values were registered in the beginning of the assistance program, and final values were registered after the children had participated in health promotion activities, which included weekly supervised brushing sessions, individual dietary guidance, collective instructive activities in which parents were present, adjusting of the oral environment, as well as restorative and surgical dental care, during an average period of six months. The studied sample comprised fourty-two children, with an average age of nine years, who presented an average of four teeth affected by caries. The technique of indirect documentation, by means of documental research, was employed. The following results were obtained: initial VPI = 29%; final VPI = 11%; initial GBI = 13% and final GBI = 5%. The observed variations were statistically significant at the level of 1%, which was revealed by the applied statistical test. The program proved efficient as to plaque control, reducing VPI to a more acceptable level. Although GBI presented considerable reduction, the presence of bleeding at the end of the program calls for a better approach in motivating patients as to regular oral hygiene.

Dental Caries and Periodontal Disease in Brazilian Children and Adolescents with Cerebral Palsy

The aim of the present study was determine the prevalence and factors associated with dental caries and periodontal disease in Brazilian children and adolescents with cerebral palsy (CP). This is a cross-sectional study conducted with 80 patients ranging in age from 2 to 18 years old. Oral exams were conducted by an examiner with records of DMFT, dmft, Gingival Bleeding Index (GBI) and Community Periodontal Index (CPI). The statistical analysis used Poisson Regression with robust variance estimation (α = 0.05). The prevalence of dental caries was 59.3%, with DMFT and mean dmft of 1.71 ± 2.42 and 2.22 ± 3.23, respectively. The mean GBI was 22.44%, and in the CPI, the prevalence of gingival bleeding, calculus, shallow and deep pockets were 94.73%, 79.62%, 12.90% and 3.22%, respectively. The caregiver’s educational level of less than eight years were associated with the dental caries experience (PR = 1.439; 95%CI = 1.09–1.89). The periodontal alterations were associated with female sex (PR = 0.82; 95%CI = 0.69–0.97), caregiver’s educational level of less than eight years (PR = 1.15; 95%CI = 1.03–1.29), poor oral perception (PR = 0.89; 95%CI = 0.80–0.98), serious communication problem (PR = 0.87; 95%CI = 0.76–0.99) and athetoid type of CP (PR = 0.85; 95%CI = 0.75–0.97). The patients with CP presented high dental caries experience and periodontal alterations, which were associated with their demographic, socioeconomic, oral health perception and systemic information.

Anti-adherent activity of Rosmarinus officinalis essential oil on Candida albicans: an SEM analysis

Objetivo: Avaliar a atividade antiaderente do oleo essencial de Rosmarinus officinalis (Alecrim) sobre Candida albicans (ATCC289065). Metodologia: O oleo essencial de R. officinalis foi avaliado nas concentracoes 0,56 mg/mL; 1,12 mg/mL e 2,25 mg/mL, atraves de Microscopia Eletronica de Varredura (MEV). Adicionou-se, em tubos de vidro estereis: 1 corpo de prova de resina acrilica; 2 mL de caldo Sabouraud-Dextrose; 0,2 mL do inoculo fungico e 2 mL do oleo essencial de R. officinalis nas concentracoes testadas. Agua destilada esteril e nistatina (100.000 UI/mL) funcionaram como controle. Os produtos testados foram adicionados em duas condicoes: junto aos demais componentes do dispositivo de aderencia (t=0h); e apos 24 h da insercao desses componentes (t=24 h). Os tubos foram incubados a 37 oC durante 48 h. Os especimes foram fixados e preparados para analise em MEV. Resultados: Na concentracao 0,56 mg/mL o oleo essencial de R. officinalis, foi semelhante a nistatina (t=0 h e t=24 h). Na concentracao 2,25 mg/mL, o produto natural provocou inibicao significativa da aderencia e rompimento celular. Efeito intermediario foi observado em 1,12 mg/mL. Maior inibicao da aderencia foi observada em t=24 h. Conclusao: O oleo essencial de R. officinalis apresentou atividade antiaderente sobre C. albicans. Maior inibicao da aderencia foi observada para o estado de agregacao celular (t=24 h) e maior concentracao do produto natural.

Atividade antifúngica de extratos vegetais brasileiros sobre cepas de Candida

Objective: To evaluate the antifungal activity of Brazilian plant extracts against strains of Candida albicans (ATCC289065) – C1, C. tropicalis (ATCC40042) – C2 and C. krusei (ATCC40147) – C3. Methods: The evaluated Brazilian plat extracts were represented by essential oils from Citrus aurantium (orange), Citrus limmom (lemon), Citrus reticulata (mandarin), Xylopia brasiliensis (pindaiba), Campomanesia xanthocarpa (guabiroba), Ocimum basilicum (basil) and Cymbopogon martinii (palmarosa). The antifungal activity of essential oils was determined by agar diffusion technique. Fungal suspensions (1.5 x 106 organisms/mL) were sowed in Sabouraud Dextrose Agar, over which were distributed discs of sterile paper. The specimens were inundated with 20μL of tested solutions and control in pure formulation. The tests were performed in duplicate and Chlorhexidine Digluconate (0.12%) served as control. The inhibition areas of fungal growth, in millimeters, were measured and analyzed descriptively. Results: For C. aurantium, C. limmom, C. reticulata, X. brasiliensis, C. xanthocarpa, O. basilicum, C. martinii and Chlorhexidine the average of the inhibition zones of growth were, respectively: 14.5, 9.0, 11.5, 11.5, 20.0, 30.0, 40.0, 22.0 (C1), 16.5, 8.0, 10.5, 9.0, 36.0, 44.0, 36.0, 26,0 (C2), and 40.0, 8.0, 10.0, 9.5, 18.0, 34.0, 36.0, 22.0 (C3). Conclusions: All products tested presented antifungal activity, highlighting the essential oils from C. xanthocarpa, O. basilicum and C. martinii, with greatest inhibition zones of fungal growth. DESCRIPTORS: Biological products. Oral candidiasis. Products with antimicrobial action

ATIVIDADE ANTIFÚNGICA DE ANTISSÉPTICOS BUCAIS SOBRE CANDIDA SPP.

Objective: To verify the in vitro antifungal activity of the mouthwashes Malvatricim® (P1), Colgate Plax® (P2), Oral B®(P3) and Colgate Periogard® (P4) on Candida albicans (ATCC 40277), Candida albicans (ATCC 289065), Candida krusei(ATCC 40147), Candida tropicalis (ATCC 13803) and Candida tropicalis (ATCC 40042). Material and Methods: Fungal suspensions were prepared (106 microrganisms / mL) and seeded on Petri dishes containing Sabouraud Dextrose Agar 4%. It was followed the agar diffusion method by means of the wells technique. Into each well were inserted 50 μL of the products as in their commercial formulation. Nystatin 1:100.000 IU (P5) was used as positive control. The plates were incubated in bacteriological incubator at 37oC for 48h. Tests were performed in triplicate and compared to positive control. The mean diameter of growth inhibition halos (MDGI)promoted by the substances was calculated and represented the antimicrobial activity. Results: P4 has showed the most potent activity against C. albicans (ATCC-289065), C. krusei(ATCC-40147), C. tropicalis (ATCC-40042), and C. tropicalis(ATCC-13803), with MDGI of 15.0mm; 15.0mm; 18.0mm and 14.3mm, respectively. C. albicans strain (ATCC-40277) was the only one susceptible to P1 (MDGI=25.3mm) and resistant to P5. The mouthwashes P2, P3 and P4 have presented antimicrobial activity against all strains assessed. Conclusion: It is concluded that the products under study, excepting Malvatricim®, have showed inhibitory activity on all strains assayed. Colgate Periogard® has presented the best activity on the strains investigated, followed by Colgate Plax®, Oral B® and Malvatricim®. DESCRIPTORS Dental prophylaxis. Microbiology. Fungi.
