ABSTRACT
Statement of Problem: Early childhood caries can cause pain, discomfort and also inability to have a healthy nutrition .Malnutrition can be characterized when there is a weight, height, and body mass index [BMI] deficiency
Purpose: The aim of this study was to evaluate the relationship between the severe early childhood caries [based on the dmft index] and BMI in pre-school children in Shiraz
Materials and Method: A descriptive analytical cross-sectional study was enrolled on 202 healthy preschool children with the age range of 3-6 years recruited from the kindergartens of different socio- economical parts of Shiraz, Iran. The Anthropometric measurements, weight and height were evaluated. The Z-scores were calculated employing WHO Anthro software [www.who.int/childgrowth/software/en/ index.html] to elucidate the subject's status on the age- and sex-specific growth chart. Every Child who has received two Z-scores under the normal value [< -2] was considered as abnormal. The relationship between dmft index and BMI was then investigated
Results: The mean of dmft was 4.13. From children with severe early childhood caries, 12.5%were under weight, 5% had height deficiency and 19.5% had BMI deficiency, however, there was no significant relationship between increasing dmft and the height, weight and BMI deficiency
Conclusion: There was not a linear correlation between severe early childhood caries and BMI, height, and weight deficiency. An incidence of 55% was yielded for severe early childhood caries which was an additional finding of this study
ABSTRACT
Hypophosphatasia is a rare inherited disorder characterized by deficient activity of tissue non-specific alkaline phosphatase [found in the bone, liver and kidney] which leads to abnormal bone and tooth mineralization. The symptoms are highly variable in their clinical manifestation, ranging from stillbirth without mineralized bone to early loss of primary teeth without bone symptoms. The diagnosis is based on low levels of serum alkaline phosphatase and increased serum or urine concentrations of phosphoethanolamine, pyridoxal 5 '-phosphate and inorganic pyrophosphate. Six clinical forms of Hypophosphatasia are currently recognized: prenatal [lethal], prenatal benign, infantile, childhood, adult and odontohypophosphatasia. A 27-month-old girl was referred to the Paediatric Dentistry Department of Shiraz Dental School with chief complaint of spontaneous loosening and shedding of anterior deciduous teeth. In clinical examination, it was noticed that, teeth number 61, 62, 71, 72 and 81 were absent. There was no sign of gingival inflammation. According to the height and weight curves, growth of patient was below the normal rate. About 1 year delay in the date of her standing or walking capability was recorded in the patient's medical history. Also there was a history of foot pain and early fatigue. CBC, serum alkaline phosphatase and urine phosphoethanolamine tests were requested for the patient. Results showed decreased serum alkaline phosphatase and increased urine phosphoethanolamine. In histological survey of exfoliated teeth, the absence of cementum on root surfaces was detected. Also, the patient's physician reported skeletal deformities and defective mineralization in her hands and feet
