Comparative analysis of pink and white esthetics of anterior full veneer crown: Indian scenario.

A goal of modern dentistry is to make an esthetic outcome as one of the major modalities in dental treatment. In recent years, more emphasis has been given to esthetic parameters, especially in the anterior regions. The aim of this study was to evaluate the presence of change in pink and white esthetics scores after giving crowns in a single tooth. Subjects for this retrospective study were chosen by randomization from June 2019 to May 2020. A total of 120 subjects were selected which were equally divided with respect to age and gender. The analysis was done with a photographic assessment. The study test was done using paired t-test, and the correlation was evaluated using the Chi-square test. In this study, we observed that there is an increase in pink and white esthetic scores (WES) after the prosthesis is delivered. There was a clinical and statistically significant difference seen with the WES and total score, whereas only clinical but no statistical difference was seen with the pink esthetic score. After giving crowns, there is an increase in overall esthetic score. It is important to have certain standardized indices to score esthetics by which the overall esthetic outcomes can be improved. One such popular index is the pink and white esthetic index, which scores the soft and hard tissue.

Effectiveness of local and topical anesthesia during gingival retraction / Eficácia da anestesia local e tópica durante a retração gingival

Objective: To compare the effectiveness of local and topical anesthesia during gingival retraction in prepared abutment teeth. Material and Methods: 72 patients desiring full mouth rehabilitation or bilateral fixed partial denture in the same arch were selected based on the inclusion criteria framed and were randomly allocated into Groups A and B of 36 each. Patients in Group A received gingival retraction with topical anesthesia and Group B received gingival retraction with infiltration anesthesia. All the patients were tested for pain, discomfort and bleeding during gingival retraction. Results: There was no significant difference in pain, discomfort and gingival bleeding (P >.05) during gingival retraction using topical and local anesthetic agents. Conclusion: Topical anesthesia was equally effective as infiltration anesthesia in managing the pain, discomfort and bleeding during gingival retraction by cord packing in prepared abutment teeth.

Objetivo: Comparar a eficácia da anestesia local e tópica durante a retração gengival previa a moldagem em dentes pilares preparados. Material e Métodos: Foram selecionados 72 pacientes indicados para reabilitação bucal total ou prótese parcial fixa bilateral na mesma arcada com base nos critérios de inclusão formulados e alocados aleatoriamente nos Grupos A e B com 36 pacientes cada. Os pacientes do Grupo A receberam retração gengival com anestesia tópica e no Grupo B receberam retração gengival com anestesia infiltrativa. Todos os pacientes foram testados para dor, desconforto e sangramento durante o procedimento. Resultados: Não houve diferença significativa na dor, desconforto e sangramento gengival (P>. 05) durante a retração gengival com anestésicos tópicos e locais. Conclusão: A anestesia tópica foi tão eficaz quanto a anestesia de infiltração no controle da dor, desconforto e sangramento durante a retração gengival com fio retrator gengival em dentes pilares preparados.(AU)

Comparative analysis of different impression techniques in relation to single tooth impression.

It is of interest to compare the accuracy of three different impression techniques for a single tooth impression. We used 3 groups with 15 samples each in this study. Group 1: Putty and light body in a sectional stock tray; Group 2: Monophase and extra light body in a sectional stock tray; Group 3: Matrix impression technique. 15 impressions were taken of a prepared tooth on a typodont with each technique. The dimensions of the casts poured from these impression techniques were compared with the control typodont tooth. Data analysis shows that the matrix impression technique gave the best results in terms of dimensional study followed by monophase and extra light body impression technique and putty and light body impression technique gave the least accurate results. The results show that there is a statistically significant difference between the three impression techniques in terms of dimensional stability. Data analysis shows that the matrix impression technique gave the best results in terms of dimensional study followed by monophase and extra light body impression technique and putty and light body impression technique gave the least accurate results. The variations between the groups are within acceptable limits. Hence, it can be concluded that all the impression techniques will result in adequate dimensional stability and can be used in clinical scenarios.
