AVALIAÇÃO DE MICRONÚCLEO APÓS A APLICAÇÃO DE AGENTES DESSENSIBILIZANTES: UM ENSAIO CLÍNICO RANDOMIZADO

O objetivo deste trabalho foi avaliar as células gengivais de pacientes com hipersensibilidade dentinária (HD), através de teste de micronúcleo, após a aplicação de agentes dessensibilizante em pacientes selecionados nos laboratórios de práticas clínicas do curso de Odontologia do Centro Universitário Franciscano (UNIFRA), Santa Maria, RS. Participaram do estudo quatorze pacientes, de ambos os sexos, classificados em dois grupos, teste (6) e controle (8). A avaliação foi feita através do biomonitoramento da superfície exposta ao agente. Para este fim, adotou-se o teste de micronúcleo, que evidenciou a presença ou não de carcinógenos, refletindo na incidência de eventos genotóxicos sobre a mucosa bucal. A coleta de material foi feita através da citologia esfoliativa na região onde os pacientes apresentaram HD aos estímulos térmicos, táctil e/ou osmóticos.  As lâminas foram coradas pela coloração de Giemsa que serviram para a avaliação da freqüência de micronúcleo e das alterações metanucleares. Os resultados demonstram pouca variação entre os espécimes estudados em relação ao número de micronúcleos, que variou de zero a dez micronúcleos por amostra estudada, sem diferenças importantes entre os grupos. Portanto, a utilização do gel teste parece não aumentar a incidência de eventos genotóxicos. Entretanto, um número maior de observações deve ser avaliado para confirmas estes achados

Xerostomia impacts oral health-related quality of life in individuals with end-stage renal disease

ABSTRACT Objective: This two-centre cross-sectional study aimed to evaluate whether xerostomia occurrence is associated with oral health-related quality of life (OHRQoL) in patients with end-stage renal disease (ESRD) after the adjustment for potential confounders. Methods: Oral examinations were performed by calibrated examiners for untreated dental caries, periodontitis and tooth loss in 180 adults with ESRD. The presence of xerostomia was determined using the global question “How often does your mouth feel dry?”. OHRQoL was evaluated by the simplified version of the Oral Health Impact Profile (OHIP14) questionnaire. Multivariate zero-inflated negative binomial regression analysis was used to calculate the incidence rate ratios (IRR) for the nonzero scores and odds ratios (OR) of having no impact in OHIP14 scores according to the presence of exposure. Results: In the adjusted model, xerostomia (IRR = 1.57; 95% CI: 1.12 to 2.20) was associated with poorer OHRQoL. The adjusted domain-specific analysis revealed that xerostomia occurrence significantly impacted the psychological disability and social disability, and the chance of having no impact was lower for the psychological discomfort domain (OR = 0.84; 95% CI: 0.12 to 0.98). Conclusion: Xerostomia exert an impact on OHRQoL in patients with ESRD, mainly in the psychological and social disabilities constructs

Staining and calculus formation after 0.12% chlorhexidine rinses in plaque-free and plaque covered surfaces: a randomized trial

OBJECTIVES: Studies concerning side effects of chlorhexidine as related to the presence of plaque are scarce. The purpose of this study was to compare the side effects of 0.12% chlorhexidine gluconate (CHX) on previously plaque-free (control group) and plaque-covered surfaces (test group). METHODS: This study had a single-blind, randomized, split-mouth, 21 days-experimental gingivitis design, including 20 individuals who abandoned all mechanical plaque control methods during 25 days. After 4 days of plaque accumulation, the individuals had 2 randomized quadrants cleaned, remaining 2 quadrants with plaque-covered dental surfaces. On the fourth day, the individuals started with 0.12% CHX rinsing lasting for 21 days. Stain index intensity and extent as well as calculus formation were evaluated during the experimental period. RESULTS: Intergroup comparisons showed statistically higher (p<0.05) stain intensity and extent index as well as calculus formation over the study in test surfaces as compared to control surfaces. Thus, 26.19% of test surfaces presented calculus, whereas calculus was observed in 4.52% in control surfaces. CONCLUSIONS: The presence of plaque increased 0.12% CHX side effects. These results strengthen the necessity of biofilm disruption prior to the start of CHX mouthrinses in order to reduce side effects

Efficacy of Gluma Desensitizer® on dentin hypersensitivity in periodontally treated patients Eficácia do Gluma Desensitizer® sobre hipersensibilidade dentinária em pacientes periodontalmente tratados

The aim of this double-blind, controlled, split-mouth designed clinical trial was to assess the effect of a single application of Gluma Desensitizer® on alleviating dentin hypersensitivity. Twelve subjects entered the study and ten completed the protocol. Each subject had two teeth treated: one with Gluma Desensitizer® according to the manufacturer's instructions and one with water. The assessment of pain was performed with the VAS (Visual Analogue Scale), after tactile (probe), thermal (cold blast of water) and thermal/evaporative (cold blast of air) stimuli at baseline, immediately after treatment, after 1 week and after 4 weeks. The mean VAS values for the test and control teeth were compared by the paired t test (alpha = 0.05). Repeated measurements ANOVA was used to compare the different experimental times. The results showed that for test teeth, at baseline, mean VAS values were 1.76 (&plusmn; 2.82), 7.10 (&plusmn; 2.10) and 4.75 (&plusmn; 2.65), and, after 4 weeks, the mean values were 1.70 (&plusmn; 2.31), 5.50 (&plusmn; 3.30) and 4.61 (&plusmn; 3.14), respectively for probe, water and air stimuli. For the control teeth, at baseline, the mean VAS values were 1.86 (&plusmn; 2.92), 6.61 (&plusmn; 2.31) and 4.08 (&plusmn; 2.91) and, after 4 weeks, 2.66 (&plusmn; 3.07), 6.32 (&plusmn; 2.94) e 4.76 (&plusmn; 3.26).There were no statistically significant differences between test and control teeth at any time. No intra-group differences were demonstrated either. It was concluded that Gluma Desensitizer® had no effect on hypersensitive teeth from periodontally treated patients for a period up to 4 weeks.<br>O objetivo deste estudo clínico duplo-cego, controlado, de boca-dividida foi avaliar o efeito de uma aplicação única do Gluma Desensitizer® no alívio da hipersensibilidade dentinária. Doze sujeitos participaram do estudo, sendo que destes dez completaram o estudo. Cada um dos participantes teve dois dentes tratados, um com o Gluma Desensitizer®, de acordo com as orientações do fabricante, e o outro com água. Para a avaliação da dor foi utilizada a EVA (Escala Visual Analógica), após os estímulos táctil (sonda), térmico (jato de água frio) e térmico/evaporativo (jato de ar frio) no início do experimento, imediatamente após o tratamento, uma e quatro semanas após. Os valores médios encontrados na EVA foram comparados pelo teste-t pareado (alfa = 0,05). Para os diferentes tempos experimentais utilizou-se ANOVA para medidas repetidas. Os resultados mostram que, no início do tratamento, os valores médios foram de 1,76 (&plusmn; 2,82), 7,10 (&plusmn; 2,10) e 4,75 (&plusmn; 2,65) para os dentes teste e, após quatro semanas, os valores médios foram de 1,70 (&plusmn; 2,31), 5,50 (&plusmn; 3,30) e 4,61 (&plusmn; 3,14) respectivamente para os estímulos sonda, água e ar. Para os dentes controle, no início do tratamento, os valores médios segundo a EVA foram de 1,86 (&plusmn; 2,92), 6,61 (&plusmn; 2,31) e 4,08 (&plusmn; 2,91) e, após 4 semanas, 2,66 (&plusmn; 3,07), 6,32 (&plusmn; 2,94) e 4,76 (&plusmn; 3,26). Não ocorreram diferenças estatisticamente significativas entre os dentes teste e controle em nenhum dos tempos experimentais. Também não ocorreram diferenças intragrupo. Concluímos que o Gluma Desensitizer® não tem efeito sobre a hipersensibilidade dentinária de pacientes periodontalmente tratados num período de até quatro semanas
