Antiplaque and antigingivitis effect of Lippia Sidoides: a double-blind clinical study in humans

OBJECTIVES: The antiplaque and antigingivitis effect of Lippia Sidoides (LS) was evaluated in this in vivo investigation. MATERIAL AND METHODS: Twenty-three subjects participated in a cross-over, double-blind clinical study, using 21-day partial-mouth experimental model of gingivitis. A toothshield was constructed for each volunteer, avoiding the brushing of the 4 experimental posterior teeth in the lower left quadrant. The subjects were randomly assigned initially to use either the placebo gel (control group) or the test gel, containing 10% LS (test group). RESULTS: The clinical results showed statistically significant differences for plaque index (PLI) (

Acidentes ocupacionais na graduação em odontologia: retrospectiva de 10 anos - doi:10.5020/18061230.2009.p240

Objective: To investigate occupational accidents that occurred during the first 10 years of Fortaleza University (UNIFOR) Dental School. Methods: A documental study based on secondary data from the Notification Center of Occupational Accidents of UNIFOR Dental School, reported in the last 10 years. The variables included characteristics of the accidents and of the injured, besides the type of instrument and the resulting injury. Results: Were recorded 160 occupational accidents divided by location, function of the injured and type of accident. It was observed that 63.1% of cases occurred in the Multidisciplinary Clinic, 23.1% in the Integrated Clinic, 8.8% in the laboratories, 1.9% at home, 1.25% in the Surgical Center, 1.25% in the Material Sterilization Central and 0.6% during the training outside university. Concerning the injured, 90.6% of the victims were undergraduates, 5.0% staff, 3.8% teachers and 0.6% patients. Regarding the injury, 40.6% were penetrating bloody injuries, 11.9% cutting bloody injuries, 2.5% cutting non-bloody injuries, 5% burns, 5% penetrating bloody injuries/cutting bloody injuries, 2.5% were injuries with maceration, 1.9% injuries causing ocular trauma and 0.6% of an incident of dog bite. Conclusion: It was concluded that penetrating injuries were prevalent and these occurred mostly in the multidisciplinary clinic, where students of earlier periods of dental course work, indicating that the experience in dental practice generates more care with safety.Objetivo: Investigar os acidentes ocupacionais ocorridos durante os 10 primeiros anos do curso de Odontologia da Universidade de Fortaleza (UNIFOR). Métodos: Estudo de natureza documental baseado em dados secundários do Centro de Notificações de Acidentes Ocupacionais do Curso de Odontologia, informados nos últimos 10 anos. As variáveis estudadas contemplaram características dos acidentes e dos acidentados, além do tipo de instrumento e da lesão resultante. Resultados: Foram registrados 160 acidentes ocupacionais divididos por local, função dos acidentados e tipo de acidente. Foi observado que 63,1% dos casos ocorreram na Clínica Multidisciplinar, 23,1% na Clínica Integrada, 8,8% nos laboratórios, 1,9% em casa, 1,25% no Centro Cirúrgico, 1,25% na Central de Esterilização de Material (CEM) e 0,6% durante o Estágio Extramuro. Com relação ao acidentado, 90,6% das vítimas eram alunos de graduação, 5,0% funcionários, 3,8% professores e 0,6% eram pacientes. Em relação às lesões, 40,6% eram do tipo perfurante cruento, 11,9% lesões do tipo cortante cruento, 2,5% lesões do tipo cortante não cruento, 5% queimaduras, 5% lesões do tipo perfurante cruento/cortante cruento, 2,5% lesões do tipo maceração, 1,9% lesões causando trauma ocular e 0,6% um incidente de mordida de cachorro. Conclusão: Concluiuse que as lesões perfurantes foram prevalentes e estas ocorreram, em sua maioria, na clínica multidisciplinar, local onde os alunos de períodos iniciais do curso atuam, indicando que a experiência na prática odontológica gera mais cuidados com a segurança no trabalho

The subjects were randomly assigned initially to use either the placebo gel (control group) or the test gel, containing 10% LS (test group). RESULTS: The clinical results showed statistically significant differences for plaque index (PLI) (p<0.01) between days 0 and 21 in both groups, however only the control group showed statistically significant difference (p<0.01) for the bleeding (IB) and gingival (GI) index within the experimental period of 21 days. On day 21, the test group presented significantly better results than the control group with regard to the GI (p<0.05). CONCLUSIONS: The test gel containing 10% LS was effective in the control of gingivitis
