Diagnóstico diferencial das manifestações das sífilis e da Aids com líquen plano na boca: relato de caso / Differential diagnosis of manifestations of syphilis and Aids with lichen planus in mouth: case report

A sífilis segue um curso semiológico em que aparece, desaparece e ressurge com variados sinais e sintomas, exigindo dos examinadores conhecimentos clínicos e laboratoriais que os conduzam ao seu diagnóstico. A disseminação do Treponema pallidum envolve praticamente todos os sistemas orgânicos,dificultando diagnósticos e justificando a histórica consagração de que a sífilis é uma grande simuladora de várias outras doenças. A mucosa bucal é importante área sinalizadora para o reconhecimento da doença através de exame clínico sistemático e detalhado. Infelizmente, a incidência e prevalênciade sífilis no mundo não expressa sinais claros de pronunciada diminuição, sobretudo na América Latina e nos países ditos emergentes. O propósito dopresente trabalho é relatar o caso de um paciente com manifestações clínicas de sífilis e aids (síndrome da imunodeficiência adquirida) na boca, que foram primariamente interpretadas como líquen plano.

Syphilis follows a semiological course in which it appears, disappears, and reappears with various signs and symptoms, demanding clinical and laboratorial knowledge that lead to its diagnosis from examiners. The dissemination of Treponema pallidum involves practically all of the organic systems, complicating diagnosis and justifying the historic consecration that syphilis is a large simulator of various other diseases. The oral mucosa is an important signalizing areafor disease recognition by way of a systematic and detailed clinical examination. Unfortunately, the incidence and prevalence of syphilis in the world does notexpress clear signs of pronounced decrease, especially in Latin America and in the so-called emerging countries. The purpose of the present study is to report thecase of a patient with clinical oral manifestations of syphilis and aids (acquired immunodeficiency syndrome) that were primarily interpreted as lichen planus

Comparative study of the polyvinyl siloxane technique with resin-splinted transfer copings used for multiple implant abutment impressions.

UNLABELLED: STATEMENTS OF PROBLEM: The lack of passivity in implant dentistry may result in failures. Therefore, impression is the first procedure in the fabrication of a passive prosthesis. The aim of this study is to compare the polyvinyl siloxane technique with a resin-splinted transfer copings used for multiple implant abutment impression. METHODS: A master cast was obtained from an edentate ridge. From the master cast, 30 casts were obtained using 3 different impression techniques. Control technique was made with polyvinyl siloxane. Resin-splinted transfer copings in condensation siloxane or irreversible hydrocolloid were used as test. The distances between analogs were obtained using a profile projector. Statistical analysis was carried out using 1-way analysis of variance. RESULTS: No significant difference among the 3 impression techniques (P > 0.05) was observed. CONCLUSION: Resin-splinted transfer copings in condensation siloxane or irreversible hydrocolloid produced impressions as accurately as polyvinyl siloxane.
