OBJECTIVE: This study was carried out to relate periodontal status to the oral lesions in patients with oral lichen planus (OLP). MATERIALS AND METHODS: Periodontal status was evaluated in 90 patients with OLP and in 52 controls, in terms of the plaque index (PII), simplified calculus index (CIS) and periodontal disease index (PDI). RESULTS: No significant differences were observed between the two groups as regards the different periodontal indices. The plaque and calculus indices were higher in the more extensive forms of OLP (P ‫؍‬ 0.02 and P ‫؍‬ 0.012, respectively), and in the presence of gingival involvement (P ‫؍‬ 0.004 and P ‫؍‬ 0.04). A significant association was also observed between the presence of atrophic-erosive lesions and increased periodontal deterioration (P ‫؍‬ 0.037). CONCLUSIONS: Increased plaque and calculus deposits are associated to a significantly higher incidence of atrophic-erosive gingival lesions in patients with OLP.

Resumen: Las enfermedades vesículo-ampollares de la mucosa oral pueden estar producidas por agentes mecánicos, físicos o químicos, por microorganismos, o por desórdenes inmunológicos o alérgicos. Dentro de los procesos ampollares de base inmunológica se encuentran el eritema exudativo multiforme, el pénfigo vulgar, el penfigoide, el liquen plano, el lupus eritematoso, la dermatitis herpetiforme y la enfermedad por depósito lineal de IgA. Este artí-culo presenta una revisión de los diferentes aspectos etiopatogénicos, clínicos, y terapéuticos de los penfigoides dentro de las enfermedades ampollares de la cavidad oral. Además se realiza una puesta al día, exponiendo los criterios diagnósticos, así como las técnicas más importantes empleadas en el mismo. A review is provided of the different etiopathogenic, clinical and therapeutic aspects of pemphigoid disorders among the range of ampullar diseases of the oral cavity. An update is also provided, with a description of the diagnostic criteria and principal techniques employed. Milián-Masanet MA, Sanchis-Bielsa JM. Penfigoides: revisión y puerta al día.
