Clinical and Radiographic evaluation of mixture of Zinc Oxide powder and Nanohydroxyapatite as an obturating material in primary molars / Avaliação clínica e radiográfica da associação do pó de óxido de zinco com nanohidroxiapatita como um material obturador utilizado em primeiros molares

Pulpectomy is the treatment alternative in rescuing the pulpally involved carious primary teeth. Various obturating materials are being used to conserve an infected deciduous dentition. The present study documents the use of a novel obturating material in primary molars due to the disadvantages associated with of the currently used materials. Objective: To evaluate clinically and radiographically the success rate of the mixture of zinc oxide powder and nanohydroxyapatite with saline as an obturating material in primary molars and also to compare its efficiency with Endoflas. Material and Methods: Thirty pulpectomy indicated primary molars were randomly divided into two equal groups; Group I (mixture of zinc oxide powder and nanohydroxyapatite with saline) and Group II (Endoflas FS). The teeth were evaluated using various clinical and radiographic criteria at 3, 6 and 9-month intervals. The obtained results were statistically analyzed (P <0.05). Results: The overall present study findings revealed 100% clinical success in both the groups. Whereas radiographically, success reported was 66% for Group I and 100% for Group II at the end of 9 months followup. The difference in the radiographic success rate between the two groups was statistically significant (P <0.05). Conclusion: Endoflas FS had demonstrated high success rate both clinically and radiographically when compared to the novel combination of a mixture of zinc oxide powder and nanohydroxyapatite with saline as obturating material.

Pulpectomia é uma alternativa de tratamento que visa resgatar polpas envolvidas em processos cariosos de dentes decíduos. Vários materiais obturadores estão sendo usados para conservar a dentição decídua infectada. O presente estudo relata o uso de um novo material obturador em molares decíduos devido às desvantagens dos materiais atualmente utilizados. Objectivo: Avaliar clínica e radiograficamente a taxa de sucesso da mistura de pó de óxido de zinco e nanoidroxiapatita como material obturador em molares decíduos e também comparar sua eficiência com Endoflash. Material e Métodos: Trinta molares decíduos que foram indicados para pulpectomias foram divididos aleatoriamente em dois grupos iguais; Grupo I (mistura de pó de óxido de zinco e nanoidroxiapatita) e Grupo II (Endoflash). Os dentes foram avaliados utilizando vários critérios clínicos e radiográficos em intervalos de 3, 6 e 9 meses. Os resultados obtidos foram analisados estatisticamente (P <0,05). Resultados: Os achados gerais do presente estudo revelaram sucesso clínico de 100% em ambos os grupos. Enquanto que radiograficamente, o sucesso relatado foi de 66% para o Grupo I e 100% para o Grupo II ao final de 9 meses de acompanhamento. A diferença na taxa de sucesso radiográfico entre os dois grupos foi estatisticamente significante (P <0,05). Conclusão: O Endoflas demonstrou alta taxa de sucesso tanto clínica como radiograficamente quando comparado à nova combinação de pó de óxido de zinco e nanoidroxiapatita como material obturador (AU)

Pioneering Strategies for Relieving Dental Anxiety in Hearing Impaired Children: a Randomized Controlled Clinical Study.

STATEMENT OF THE PROBLEM: Hearing impaired children have a problem in understanding and comprehending with dental treatments. Visual language is the sensible answer of how to improve communication with them. PURPOSE: To evaluate the applicability of dental sign language in Hearing impaired children in relieving anxiety during stressful dental treatment by improving their means of communication. MATERIALS AND METHOD: This randomized clinical trial was carried out in the Department of Pedodontics and Preventive Dentistry which included 40 Hearing Impaired children meeting inclusion criteria. The selected children were randomly divided into the study and control group comprising of 20 each. In the control group, initial oral examination and dental treatment (oral prophylaxis and class I restoration) were performed without the use of dental sign language. In the study group, the dental sign language specific to dental treatment was educated and during their subsequent visit to the dental clinic after dental sign language reinforcement, oral prophylaxis and class I restoration were done. Subjective and objective measurements of anxiety were recorded for both groups using facial image scale (FIS), pulse oximeter and electronic blood pressure apparatus to compare for correlation. The obtained data were subjected to statistical analysis using unpaired t-test. RESULTS: There was a statistically significant reduction in the anxiety levels (p< 0.05) in the study group compared to the control group. CONCLUSION: Dental sign language was effective in reducing the level of anxiety in children who are hard of hearing. Dental sign language was able to improve behavior positively during dental treatment and may also aid in developing a positive dental attitude among children who are hard of hearing.
