RESUMO
BACKGROUND: Non-syndromic cleft lip with or without cleft palate (CL/P) or cleft palate only (CPO) are orofacial clefts with multifactorial etiology. These include environmental factors and heterogeneous genetic background. Therefore, studies on different and homogenous populations can be useful in detecting related factors. The aim of the present study was to evaluate the risk factors in patients with non-syndromic cleft in Tehran, Iran. METHODS: Data from 300 patients and 300 controls were collected between 2005 and 2010. Binary logistic regression analyses were used to calculate relative risk by odds ratio (OR) and %95 confidence interval. RESULTS: Low maternal age (OR=1.06, 95% CI, 1.011-1.113), low socioeconomic status (OR=0.23, 95% CI, 0.007-0.074), maternal systemic disease (OR=0.364; 95% CI, 0.152-0.873) and passive smoking (OR=0.613, 95% CI, 0.430-0.874) increased the risk for CL/P and CPO. There was a significant difference in iron and folic acid use during pregnancy when the case and control groups were compared. CONCLUSION: In assessing for orofacial cleft risk, we should consider lack of folic acid supplementation use, maternal age and systemic diseases and passive smoking as risk factors.
RESUMO
Acute Lymphoblastic Leukemia (ALL) is the most prevalent hematological malignant tumor during childhood. Unilateral infiltration into the gums is less prevalent and more often observed in the AML type.A 12-year-old girl with symptoms of pain and swelling in the buccal vestibule and also at the posterior part of the right palate of the maxilla was referred to a private dental office. The patient had been inflicted by ALL and had undergone complete chemotherapy. A week prior to her admittance into the hospital, the workup of the patient's blood revealed her recovery. The clinical and radiographic evidence did not show any dental problems. The histological examinations on the patient's jaw revealed the correct diagnosis of ALL and the patient underwent chemotherapy for the second time.This case has been reported to point out that intraoral unilateral swelling of the upper jaw may be propounded as the primary diagnostic symptom of ALL.
RESUMO
Radicular cysts arising from deciduous teeth are rare. This report presents a case of radicular cyst associated with a primary molar following pulp therapy and discusses the relationship between pulp therapy and the rapid growth of the cyst. The treatment consisted of enucleation of the cyst sac and extraction of the involved primary teeth and 20 months follow up of the patient. Early diagnosis of the lesion would have lead to a less aggressive treatment plan.
