ABSTRACT
Background & objectives: Vertical malocclusions of the incisor teeth namely, anterior openbite and deep overbite present a challenge to the orthodontic clinicians. Determining the etiology of these is utmost important for further treatment planning and prognosis. Present study was carried out to understand the dentofacial skeletal pattern of the deep overbite in two types of deformities, Angle's Class II Div.l & Class II Div.2 (study group) and comparing them with normal occlusion (control group). Methods: Lateral cephalogram of total 60 pts, 20 in each of the above mentioned groups were analysed using 19 linear and 8 angular parameters and results of each group were compared with other two groups and conclusions were drawn. Result and conclusion: Larger posterior facial height, lower anterior facial height, lower gonial angle, larger Jaraback’s ratio & reduced lower molar height together contribute to horizontal growth pattern. It was concluded that there is more horizontal growth pattern in class II div. 2 cases hence the deepbite is more severe in class II div.2 cases compared to div.1 cases.
ABSTRACT
Background: Extraction of all 1st premolars in the orthodontic treatment of Class II div 1 malocclusion has been associated with a decrease in vertical dimension of occlusion thus predisposing the patient to TMJ disorders. Objectives: To evaluate the vertical changes occurring in patients having class II div 1 malocclusion, treated orthodontically with 1st premolar extractions & compare these changes with those occurring in patients treated orthodontically without extractions. Method: Pre-treatment & Post-treatment Lateral Cephalogram radiograph of 11 patients having CL-II div1 malocclusion treated without extraction and 16 patients treated with the extraction of all 1st premolars were analyzed and compared to observe the changes in the anterior facial height. Result: the orthodontic treatment of Cl-II div 1 malocclusion cases treated with a non-extraction approach leads to a statistically significant increase in the anterior facial height due to the downward & backward rotation of the mandible. The cases treated with the extraction of all 1st premolars also show the statically significant increase in the anterior facial height but this increase was less than that observed for the non-extraction group. Conclusion: this study does not support the theory that the first premolar extractions reduce the vertical dimension of occlusion and predispose the extraction patients to TMJ disorders.
ABSTRACT
The authors present the first case of multiple pterygium syndrome (OMIM # 265000) from Gujarat, a rare syndrome characterized by multiple pterygia, facial and skeletal anomalies. A 9-year-old female child born of consanguineous marriage, with features of arthrogryposis multiplex, multiple pterygia, hypoplastic genitalia and skeletal anomalies presented with pneumonia. A previously unreported association of Atrial Septal defect was discovered on routine 2D echocardiography, which is important for prognostication and follow-up.
ABSTRACT
Background: Salmonella typhi infection remains a serious problem in developing country. It has been estimated that approximately 12.5 million cases of typhoid fever occurs annually in the developing countries with 7.7 million cases in Asia alone. The disease is predominantly a disease of school age children and young adults and is reported to be a milder in infants and young children. Methods: A total of 150 children with clinical and/or laboratory diagnosis of typhoid fever admitted to the tertiary care level government hospital attached with the Government medical college in Pediatrics ward were reviewed during the months of JUNE to MAY for demographic data such as age, sex, clinical features, result of laboratory tests and antibiotic sensitivity in vivo. Results: There were 88 male and 62 female patients, from the age group ranging from 2 years to 12 years. Predominant symptoms were fever, abdominal pain , vomiting and headache. Hepatomegaly was almost twice as frequent as spleenomegaly. Common clinical signs of typhoid fever in adults such as relative bradycardia and rose spots were seldom documented in children. Fever, Toxic look, coated tongue and hepato-spleenomegaly were common clinical signs of clinical presentation in children. The positivity rate of WIDAL test and Blood Culture was 71.33% and 5.33% respectively. Hepatitis, Bronchitis and Encephalopathy were commonly observed complications of Multidrug resistant typhoid fever in this study. Antibiotics sensitivity in vivo revealed resistance rates of 78.12% for Ampicillin, 84.2% for Trimethoprim-Sulfamethoxazole (Co-trimoxazole), 19.5% for Ciprofloxacin, 14.28% for Ofloxacin and 20% for Cefotaxime. Conclusions : No resistance was detected against Cefixime and Ceftriaxone. Except the two patients died during the period of observation of this clinical study, all paediatrics patients survive from their illness completely.
