13. The 19-bp deletion polymorphism of dihydrofolate reductase (DHFR) and nonsyndromic cleft lip with or without cleft palate: evidence for a protective role
Objective Nonsyndromic cleft lip with or without cleft palate (NS-CL/P) are among the most common congenital birth defects worldwide. Several lines of evidence point to the involvement of folate, as well as folate metabolizing enzymes in risk reduction of orofacial clefts. Dihydrofolate reductase (DHFR) enzyme participates in the metabolic cycle of folate a

14. Dental development of children and adolescents with cleft lip and palate
Aim: To evaluate the dental development of Brazilian children and adolescents with cleft lip and palate. Methods: The sample consisted of 107 panoramic radiographs of children and adolescents with cleft lip and/or palate (cleft group) and 107 panoramic radiographs of children and adolescents without cleft lip and/or palate (control group), with chronological

15. Risk factors and the prevention of oral clefts
This article presents general aspects of risk factors and particularities of the management of individuals with oral clefts (OCs). A practical manual of prevention and management of this congenital defect was prepared based on a review of the literature and using data from Brazilian multicenter studies. Since OCs require efforts from all levels of healthcare

16. Molecular analysis of holoprosencephaly in South America
Holoprosencephaly (HPE) is a spectrum of brain and facial malformations primarily reflecting genetic factors, such as chromosomal abnormalities and gene mutations. Here, we present a clinical and molecular analysis of 195 probands with HPE or microforms; approximately 72% of the patients were derived from the Latin American Collaborative Study of Congenital

17. Evaluation of the intercanine distance in newborns with cleft lip and palate using 3D digital casts
OBJECTIVE: The purpose of this present study was to compare, by means of 3D digital casts, the anterior transverse dimension of the dental arch of newborns with and without cleft lip and palate. MATERIAL AND METHODS: The sample was composed of ninety-four children aged from 3 to 9 months divided into three study groups: Group I - children without craniofa

18. MSX1 gene and nonsyndromic oral clefts in a Southern Brazilian population
Nonsyndromic oral clefts (NSOC) are the most common craniofacial birth defects in humans. The etiology of NSOC is complex, involving both genetic and environmental factors. Several genes that play a role in cellular proliferation, differentiation, and apoptosis have been associated with clefting. For example, variations in the homeobox gene family member MSX

19. Investigação de fatores genéticos na etiologia de fendas orofaciais típicas / Investigation of genetic factors on the etiology of orofacial clefts typical
Typical oral cleft (TOC) is a prevalent and heterogeneous group of congenital defects with multiple etiologies, which remain unknown in several cases. Population studies detected several genes related to TOC. An individualized investigation, involving different laboratorial tools at same time, is an approach that can contribute on the etiological characteriz

20. TGFA/Taq I polymorphism and environmental factors in non-syndromic oral clefts in Southern Brazil
We report a study of TGFA/ Taq I polymorphisms and environmental factors in non-syndromic oral cleft in Southern Brazil. Nonsyndromic cleft case-parent triads were recruited to participate. Clinical data was collected with an emphasis on tobacco and alcohol use during pregnancy. DNA was extracted from peripheral blood and TGFA/ Taq I polymorphisms were analy

21. Evaluation of the cell block technique as an auxiliary method of diagnosing jawbone lesions
This study investigated the viability of the cell block technique as an auxiliary method of diagnosing jawbone lesions. Thirty-three clinically diagnosed jawbone lesions with a cystic appearance were subjected to aspiration. The aspirated material was processed by the cell block technique, and the lesions were biopsied and treated. Cytological findings (cell

22. Cleft lip and palate: recommendations for dental anesthetic procedure based on anatomic evidences
Patients with cleft lip and palate usually present dental anomalies of number, shape, structure and position in the cleft area and the general dentist is frequently asked to restore or extract those teeth. Considering that several anatomic variations are expected in teeth adjacent to cleft areas and that knowledge of these variations by general dentists is r

23. Caracterização de aspectos relevantes para a avaliação genético-clínica de portadores de fendas orofaciais em Alagoas / Description of relevant aspects for genetic evaluation of patients with orofacial clefts in Alagoas
As fendas orofaciais (FOF) têm prevalência mundial em torno de 1:600 nascidos-vivos. Trata-se de um grupo heterogêneo, com significativa associação a comorbidades e que demanda assistência multiprofissional, integral e especializada. No Brasil, embora exista a Rede de Referência no Tratamento de Deformidades Craniofaciais (RRTDCF), com atuação na es

24. Timing and sequence of primary tooth eruption in children with cleft lip and palate
OBJECTIVE: To determine the timing and sequence of eruption of primary teeth in children with complete bilateral cleft lip and palate. MATERIAL AND METHODS: This cross-sectional study was conducted at the Hospital for Rehabilitation of Craniofacial Anomalies of the University of São Paulo, Bauru, SP, Brazil, with a sample of 395 children (128 girls and 267
