Condições Bucais em Pacientes com Líquen Plano Oral

Objetivo: Avaliar as condicoes bucais de pacientes com liquen plano oral (LPO), comparando com um grupo controle. Metodo: Foram selecionados 17 individuos portadores de LPO e 17 nao portadores de LPO, pareados em idade e sexo. Realizou-se exame clinico bucal em todos os pacientes e foram determinados os indices CPO-D, CPI, IHOS e ISG, e as taxas de fluxo salivar em repouso e estimulado. Realizou-se analise estatistica com testes qui-quadrado e de Mann-Whitney, considerando significante p menor que 0,05. Resultados: Em ambos os grupo 82,4% dos pacientes eram do sexo feminino, a idade dos pacientes com LPO variou de 15 a 73 anos (media de 49±16 anos). No grupo LPO a media do CPO-D foi 4,18±4 e no controle foi 1,88±3,3. Quanto ao IHOS, no grupo LPO 64,7% tinha higiene oral satisfatoria e no controle 94,1%. O CPI evidenciou 70,6% doenca periodontal no grupo LPO e 41,1% no grupo controle. A media do fluxo salivar em repouso foi de 0,38±0,19 ml/min. e de 0,44±0,22 ml/min., no grupo LPO e controle, respectivamente. Houve diferenca estatisticamente significante nas medias do IHOS (p= 0,035), CPI (0,033) e CPO-D, (p=0,033). Nao houve diferenca estatisticamente significante para o fluxo salivar em repouso (p=0,200), para o fluxo salivar estimulado (p=0,381) e ISG (p= 0,381). Conclusoes: Os pacientes com LPO apresentam piores condicoes bucais e funcao normal das glândulas salivares, quando comparado com individuos sem LPO. Ressaltamos a importância do controle de fatores bucais na evolucao das lesoes do LPO. Objective: To evaluate the oral conditions in patients with oral lichen planus (OLP) and compared with a control group. Method: 17 patients with OLP and 17 age- sex- matched controls were selected. Oral examination and DMFT index, CPI, OHI-S and GSI, and unstimulated and stimulated salivary flow were determined. Statistical analysis was being applied qui-square and Mann-Whitney test, considering significant p less than 0.05. Results: In both groups of patients were 82.4% female, the patient age range with OLP was 15-73 years (maen 49±16 years). In the OLP group the mean DMFT was 4.18±4 and the control was 1.88±3.3. As for the OHI-S, 64.7% in OLP group had satisfactory oral hygiene and control 94.1%. The CPI showed 70.6% of periodontal disease in OLP group and 41.1% in the control group. The mean unstimulated salivary flow was 0.38±0.19 ml / min. and 0.44 ± 0.22 ml / min., OLP and control group, respectively. Statistically significant differences were observed in OHI-S (p=0.035), CPI (p=0.033) and DMFT (p=0.033). There was no statistically significant difference in the unstimulated salivary flow (p=0.200), stimulated salivary flow (p=0.381) or GSI (p=0.381). Conclusions: Patients with OLP had worse oral health conditions and had no dysfunction of the salivary glands. We emphasize the importance to control the oral factors in patients with OLP.
