RESUMEN
O presente artigo visa relatar um caso clínico, onde através de um procedimento cirúrgico, conseguiu-se a alteração do biótipo gengival fino para o biótipo gengival espesso com o aumento da gengiva queratinizada da região. Através da discussão e descrição detalhadas dos procedimentos cirúrgicos envolvidos conclui-se que a técnica de enxerto gengival livre é eficaz na alteração do biótipo gengival, permitindo o aumento da quantidade de gengiva queratinizada ao redor dos implantes.
This paper aimed to report a case where, through surgical procedure, it was possible to convert thin gingival biotype into thick gingival biotype, with an augment of keratinized gingiva in the region. Through detailed description and discussion of the surgical procedures utilized, it was concluded that the free gingival graft technique is effective in altering the gingival biotype allowing an augment of the quantity of keratinized gingival around the implant.

OBJECTIVES: The objective of this study was to compare, by scanning electron microscopy, the smoothness of the resected apical root surface after preparation with high-speed #699 bur, #699 bur plus Shofu finishing and Zekrya bur, and with an erbium:YAG laser. STUDY DESIGN: Thirty-nine extracted human premolars were instrumented and obturated and their root apices were resected. The roots were divided into 4 groups according to the root resection method. The teeth were dried, metallized, and analyzed at x400 by scanning electron microscopy. Scores ranging from 0 to 3 were attributed to surface smoothness. The data were analyzed by the Kruskal-Wallis test for overall comparison, and by Dunn's test for individual comparisons. RESULTS: Smoother surfaces were observed for the groups treated with the #699 bur and the #699 bur plus Shofu point finishing, while rougher surfaces were obtained with the laser, which differed significantly from the other 2 methods (P < .05). CONCLUSIONS: Treatment with the #699 bur plus Shofu finishing yielded better results in terms of surface smoothness, whereas the laser treatment produced more irregular and rougher surfaces after root resection.
