The premature extraction under general anesthesia differs significantly from the same manipulation made with local anesthesia. The aim of the study is to compare the number, the type and the position of the prematurely extracted deciduous teeth in children treated with local and under general anesthesia. Subjects of monitoring were 60 children. The clinical group consists of 30 children with te...

introduction: in restorative dentistry, selecting the proper material is an important factor for clinical success. the objective of this study was clinical evaluation of survival time of three tooth color materials in primary anterior teeth. methods: in this interventional clinical trial study, 94 deciduous anterior teeth (36 teeth in boys, 58 teeth in girls) belonging to 3-5 year old children ...

An accurate diagnosis of the morphology of the root canal system is a prerequisite for successful root canal treatment.1 Frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have an anatomical variations or additional root canals.2 Supernumerary root is a developmental condition and may involve any tooth. The incidence of ...

To isolate high-quality human postnatal stem cells from accessible resources is an important goal for stem-cell research. In this study we found that exfoliated human deciduous tooth contains multipotent stem cells [stem cells from human exfoliated deciduous teeth (SHED)]. SHED were identified to be a population of highly proliferative, clonogenic cells capable of differentiating into a variety...

In humans, deciduous tooth development begins before birth and is complete by about the fourth postnatal year. They are lost when the patient becomes 11 years old. The permanent teeth appear by 6-7 years (and later for the wisdom teeth). Most are successional, and a few are non successional. The coronal part of the human tooth is composed of two hard tissues: enamel and dentin, and this part in...

During postnatal development the female is more advanced than the male in calcification and eruption of all permanent teeth, except for the third molar. In deciduous teeth the direction is reversed; males are slightly more advanced (H. V. MEREDITH, J Dent Res 25:4366, 1946). The direction and the magnitude of prenatal dental dimorphism is of interest, but has not been systematically explored. W...

BACKGROUND Hypophosphatasia is a rare inherited disease derived from mutations in tissue non-specific alkaline phosphatase genes, with typical oral symptoms including short root anomaly and dysplasia of dentin or cementum. CASE PRESENTATION Two young female patients presented with short root anomaly with a history of premature loss of deciduous and/or permanent teeth. The laboratory and imagi...

BACKGROUND To evaluate and compare the microhardness of deciduous teeth treated with nano-hydroxyapatite and calcium sucrose phosphate after iron drop exposure. MATERIAL AND METHODS Twenty healthy anterior deciduous teeth were collected and stored in 0.9% saline solution at room temperature. All the teeth were immersed in artificial saliva in an incubator shaker at 37° for an hour and then su...

The aim of the present study was to evaluate the relationship between BMI and tooth decay in a population of Iranian children. In this cross-sectional descriptive/analytical study, 1482 children were selected from kindergartens and preschool centers in Kerman, Iran. The children underwent examination of deciduous teeth (using the dmft index) after determination of height and weight for calculat...
