Abstract

Introduction: Down syndrome (DS) is a common genetic disorder also known as Trisomy 21.DS individuals have specific physical dysmorphism especially the face. The most common features and problems associated with Down’s syndrome  are characteristic facial features, cognitive problems, congenital heart disease, hearing problems, short stature, thyroid problems and Alzheimer’s disease. This study aims to determine the differences of the vertical facial height measurement (UFH, MFH and LFH) between DS and regular (R) children. Methods: The study is a Cross-sectional analytical. Subjects are 6-13 years of age, with a total of 20 DS children (10 males; 10 females) of selected Sekolah Luar Biasa-C (SLB- Cs) and 160 R school children (80 males; 80 females) from selected Sekolah Dasar Negeri (SDNs) in Kota Bandung. Subjects selected using the three levels Multi stage cluster sampling. Measurements taken were upper, middle and lower facial height with each measurement taken three times. Data was analysed using the t-test and p-value. Results: UFH in DS males are 5.623, 5.986, 6.352, 6.396, 6.585, 6.747,7.109; MFH 3.325, 3.456, 3.457, 3.646, 3.611, 3.720, 3.716 and LFH are 4.163, 4.283, 4.235, 4.771, 4.850, 4.979, 5.132. UFH in R males are 5.924, 6.029, 6.223, 6.362, 6.476, 6.725, 6.903, 7.366; MFH 3.942, 3.998, 4.103, 4.148, 4.175, 4.247, 4.463, 4.534 and LFH 4.509, 4.658, 4.882, 5.058, 5.167, 5.450, 5.532, 5.606. In DS females UFH are 5.745, 5.912, 5.986, 6.394, 6.339, 6.778; MFH 3.575, 3.704, 3.711, 3.768, 3.749, 3.865 and LFH 4.49, 4.552, 4.646, 4.909, 5.034, 5.039. UFH for R females 6.062, 6.167, 6.243, 6.308, 6.476, 6.515, 6.799, 6.965; MFH 3.700, 3.863, 3.981, 4.084,4.091, 4.116, 4.191, 4.221 and LFH 4.576, 4.702, 3.764, 4.998, 5.156, 5.326, 5.374, 5.552 (in cm). Conclusion: There are significant differences with the MFH and LFH between DS and R children and UFH differences is non significant between these two populations.

Abstract

Introduction: Growth and development assessment in children is measured by the head circumference measurement or as known as occipital-frontal circumference. In cases of genetic abnormalities such as Down syndrome which is caused by extra chromosome 21, give distinct features in the craniofacial profile, hence the author finds it is useful to observe the changes in their growth, mainly the head circumference. The purpose of this research is to analized comparison between head circumference measurement in children with Down syndrome in Sekolah Luar Biasa-C and normal children, Methods: Type of this research is analytical with surveying technique, using cross sectional studies on 20 children with Down syndrome and 160 normal children 6 to 13 years old. The sample subject. Based on anthropometry landmark on point Glabella to Opisthocranion, measurement is taken using a non-stretchable, flexible measuring tape. Result: There are significant differences between the head circumference of children in both group according to age and gender; except age 6 male, with the mean value of children with Down syndrome compare to normal circumference measurement were smaller 3 to 5 cm behind the normal children in this research. Conclusion: The head circumference of the children with Down syndrome over all from age 6 to 13 years old were smaller than the regular children in same age and same gender.

Abstract

Introduction: The term microdontia is used when the teeth are smaller than normal. It is recognized clinically as teeth having a usual crown shape or sometimes with tapering (peg or conical) crown in lateral incisors. Microdontia is usually manifested in systemic diseases and syndromes especially Down syndrome. The cause of microdontia is unknown but it could be multifactorial. The purpose of this research was to determine the prevalence of microdontia in patients with Down syndrome. Methods: Type of research is descriptive survey. The sampling method is purposive sampling. A study was conducted in 38 Down syndrome patients, aged between 7-29 years of age, consisted of 19 males and 19 females. The teeth were examined visually. Result: a total of 23 students had microdontia of lateral incisors of either the upper or lower jaw which indicated a prevalence of 60.53%. 10 students had microdontia of lateral incisors involving the upper and lower jaw which gives out a prevalence of 26.31%. Overall, the total prevalence of microdontia in the students with Down syndrome was 86.84%. Conclusion: Prevalence of microdontia in lateral incisors among patients with Down syndrome in Kota Bandung is high. There is no statistically significant difference in microdontia prevalence between female and male Down syndrome students.
