Nasotracheal Intubation: An Overview.

INTRODUCTION: Nasotracheal intubation is the commonest method used to induce anaesthesia in oral surgery patients. It has a distinct advantage of providing good accessibility for oral surgical procedures. ANATOMY AND PROCEDURE: One must know the anatomy involved, the pathway and procedure of intubation, the pre-anaesthetic medication and complications which may be seen at the time of intubation. The surgeon must have the knowhow of the tube and the procedure which are explained in detail in the article. COMPLICATIONS: Several complications can arise while performing the procedure which may be operator induced or arising due to anatomical variations. CONCLUSION: It is prudent for the oral surgeon to know the basics of nasotracheal intubation in order to form a useful team member for management of complications arising from anaesthesia. Recent years have seen improvement in the armamentarium. These help negate the blindness of the procedure.

Comparative analysis of postcementation hypersensitivity with glass ionomer cement and a resin cement: an in vivo study.

AIM: The aim of this clinical study was to compare the postoperative sensitivity of abutment teeth restored with full coverage restorations retained with either conventional glassionomer cement (GIC) or resin cement. MATERIALS AND METHODS: Fifty patients received full-coverage restorations on vital abutment teeth. Of these, 25 were cemented with GIC (GC Luting and Lining cement) and the other 25 using an adhesive resin cement (Smartcem 2). A randomized single blind study was undertaken for acquiring and evaluating the data. The teeth were examined before cementation, after cementation, 24 hours postcementation and 7 days postcementation. A visual analog scale was used to help the patient rate hypersensitivity. RESULTS: The statistical analysis of the result was done using students paired t-test. No statistically significant difference between Smartcem 2 and GIC was observed, when tested immediately and 24 hours after cementation. Statistically significant difference was seen between Smartcem 2 and GIC when tested 7 days postcementation with a significance level of 0.05. Higher postoperative sensitivity was seen with GIC when compared to resin cement. CONCLUSION: In this study, the incidence of postoperative hypersensitivity after cementation of full-crown restorations with GIC and resin cement was similar when tested immediately. However, 7 days postcementation, abutments with GIC showed higher response compared to resin cement. CLINICAL SIGNIFICANCE: A self-adhesive resin cement can be the material of choice for luting if presence of postoperative sensitivity is of prime consideration. In case GIC is being used, patient should be informed about the presence of sensitivity for a more prolonged period than with resin cement.

Ocular prosthesis: art meets science / Prótese ocular: a arte encontra a ciência

Objective: To describe a method of fabricating of ocular prosthesis. Discussion: The conventionalmethod of painting the iris region of a scleral prosthesis has been circumvented in this method. Fabricatingan ocular prosthesis by conventional methods requires painting the scleral region. Painting the cornealregion of the prosthesis is a tedious process. This article describes an easier, faster and a more aesthetictechnique of customizing an ocular prosthesis.

Objetivo: Descrever um método de fabricação de prótese ocular. Discussão: O método convencional de pintura(caracterização) da região da íris numa prótese escleral foi modifi cado neste método. A fabricação de prótese ocular pormétodos convencionais requer pintura da esclerótica. Pintar a região corneal da prótese é um processo tedioso. Esteartigo descreve uma maneira rápida, fácil e com resultados estéticos satisfatórios de customização de próteses oculares.
