RESUMEN
Background: Autotransplantation is a minor surgical procedure which involves transplantation of teeth within the same oral cavity. For children, autotransplantation may be considered as a provisional measure with good survival probability. It offers a viable biological approach for replacing the missing teeth and also for orthodontic treatments in children. Aim: The aim of this study is to assess the knowledge, attitude, and practice of autotransplantation among pediatric dentists in Chennai, India. Methods: An 18?item questionnaire was developed, piloted, and distributed among 100 practicing pediatric dentists in Chennai, India. Descriptive statistical analysis was done using Chi?square test. Results: Seventy valid responses from the practicing pediatric dentists were obtained. Among them, 39.7% had an experience of 5–10 years, 47.1% practiced less than 5 years, and 13.2% had experience more than 10 years. Analysis of the responses showed that 76.5% of the pediatric dentists were aware of the procedure but have not observed autotransplantation being done. Among the respondents, 95.6% have not performed this technique and 40.6% of them were not sure of the prognosis. Atraumatic extraction of donor tooth was considered to be a major limitation in autotransplantation by 41.8% of the pediatric dentists. From the responses received, 95.6% were interested in gaining more information with majority opting for more hands on workshops on the technique of autotransplantation. Conclusion: Though most of the respondents were aware of autotransplantation procedure, they have not practiced it due to inadequate training
RESUMEN
Objetive: The aim of the study was to evaluate the maximum molar bite force in children aged 4 to 6 years with and without dental caries. Material and Methods: This cross sectional study was carried out from May 2018 to December 2018. A total of 288 children aged between 4 to 6 years were randomly selected from six different primary schools in Chennai city, India and divided into two groups of 144 children each, based on the presence and absence of caries: Group A children with non-carious dentition and Group B children with carious dentition. Bite force measurement was performed using standardized custom made occlusal force gauge. Statistical analysis used: Data were expressed as the mean ± SD. Student's ttest (two tailed, independent) and ANOVA were used to find the significance of study parameters between the groups. Results: Occlusal bite force of non-carious dentition (367.94 ±33.71N) was higher than the carious dentition (326.73±27.83N) and it was statistically significant (p≤0.01). Overall occlusal bite force of boys (350.44±35.84N) was significantly higher than that of girls (344.22±38.25N). Flush terminal plane molar relationship showed higher occlusal bite force (380.54±27.36N) followed by mesial step (350.82±22.25N) and distal step (310.63±20.82N) molar relationship. Conclusion: Non-carious dentition showed significantly higher bite force than carious dentition in children 4 to 6 years of age. Boys had higher bite force than the girls and flush terminal plane molar relationship showed higher bite force than mesial and distal step molar relationship.
Objetivo: El objetivo del estudio fue evaluar la fuerza de mordida molar máxima en niños y niñas de 4 a 6 años con y sin caries dental. Material y Métodos: Este estudio transversal se llevó a cabo entre mayo de 2018 y diciembre de 2018. Se seleccionó aleatoriamente un total de 288 niños y niñas de entre 4 y 6 años de seis escuelas primarias diferentes en la ciudad de Chennai, India, y se dividieron en dos grupos de 144 niños cada uno según la presencia y ausencia de caries: El grupo A incluye niños con dentición no-cariada y el grupo B incluye niños con dentición cariada. La medición de la fuerza de mordida se realizó utilizando un medidor de fuerza oclusal estandarizado hecho a medida.Análisis estadístico utilizado: Los datos se expresaron como la media ± SD. Se utilizó la prueba t de Student (dos colas, independiente) y ANOVA para encontrar la importancia de los parámetros de estudio entre los grupos. Resultados: La fuerza de mordida oclusal de la dentición no cariada (367,94 ±33,71N) fue mayor que la de la dentición cariada (326,73±27,83N) y fue estadísticamente significativa (p≤0,01). La fuerza de mordida oclusal global de los niños (350,44±35,84N) fue significativamente mayor que la de las niñas (344,22±38,25N). La relación molar en el plano terminal al ras mostró una mayor fuerza de mordida oclusal (380,54 ± 27,36 N), seguida de una relación molar de escalón mesial (350,82 ± 22,25 N) y escalón distal (310,63 ± 20,82N).Conclusión: La dentición no cariada mostró una fuerza de mordida significativamente mayor que la dentición cariada en niños de 4 a 6 años de edad. Los niños tenían una mayor fuerza de mordida que las niñas y la relación molar en el plano terminal mostró una mayor fuerza de mordida que la relación molar escalonada mesial y distal.
