Article Synopsis
  • - The study evaluated the occurrence of dental anomalies like hypodontia, hyperdontia, and canine impaction in children with nonsyndromic cleft lip and/or palate (CL/P), focusing on patients from a specialized clinic.
  • - Among 56 children aged 8-12 years, findings showed that 37.5% had hypodontia and 23.21% had hyperdontia, while the incidence of canine impaction was 5.36%, particularly affecting the cleft area.
  • - No significant effect of treatments like maxillary expansion or alveolar bone grafting on permanent canine eruption was found, but the study concluded that a certain clinical approach was effective and should be implemented more widely.

Introduction: Growth hormone deficiency (GHD) is one of the main indications for growth hormone therapy. One characteristic of this disease is bone age delay in relation to the chronological age. Pituitary dysfunction negatively affects the growth and development of the jaws and teeth of the child.

Article Synopsis
  • The study investigates the complex causes of nonsyndromic cleft lip and/or palate (NSCL/P), focusing on the potential impact of DNA repair gene polymorphisms in a Polish population.
  • Researchers analyzed 36 polymorphisms in 12 DNA damage repair genes in a group of 263 NSCL/P patients compared to a control group of 526.
  • Findings indicate that specific variants in the BRIP1 gene increase the risk of NSCL/P, suggesting it may be a new candidate gene linked to this birth defect.

The CDH1 gene plays an important role during carcinogenesis and craniofacial morphogenesis. Germline mutations in this gene have been described in families presenting syndromic diffuse gastric cancer and orofacial clefts. The aim of this study was to evaluate the association between nucleotide variants of CDH1 and the risk of non-syndromic cleft lip with or without cleft palate (NSCL/P).

Growth hormone (GH) is a polypeptide hormone produced by the cells of pituitary. Production of growth hormone is carried out in a pulsating manner, and the frequency and intensity of the pulses is dependent on age and gender. Growth hormone deficiency (GHD) is characterized by, among others, slow growth process often from early childhood, delayed bone age.

Background: Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a common structural malformation with a complex and multifactorial aetiology. Associations of abnormalities in phenylalanine metabolism and orofacial clefts have been suggested.

Methods: Eight single nucleotide polymorphisms (SNPs) of genes encoding phenylalanine hydroxylase (PAH) and large neutral l-amino acid transporter type 1 (LAT1), as well as the PAH mutation that is most common in the Polish population (rs5030858; R408W), were investigated in 263 patients with NSCL/P and 270 matched controls using high resolution melting curve analysis (HRM).

Background: Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is one of the most common congenital anomalies, with a complex and still not fully understood etiology. Given the important role of the Wnt/β-catenin pathway during craniofacial development, we decided to test the hypothesis that common polymorphic variants of the genes encoding crucial components of this signaling pathway might contribute to the risk of NSCL/P in the Polish population.

Methods: A set of 19 single nucleotide polymorphisms (SNPs) in the APC, AXIN1, AXIN2, CTNNB1, DVL2, and GSK-3β genes were analyzed using restriction fragment length polymorphism and high-resolution melting curve methods in a group of 280 patients with NSCL/P and a properly matched control group (n = 330).

Background: Tooth agenesis is one of the most common anomalies of human dentition and is due to a complex and not fully elucidated etiology. The purpose of this study was to evaluate the possibility that polymorphic variants of genes encoding the main folate and choline metabolism enzymes might be associated with the risk of hypodontia in the Polish population.

Methods And Results: We analyzed 21 polymorphisms of 13 candidate genes and found that single nucleotide polymorphisms (SNPs) in the CHDH gene are significantly correlated with the risk of dental agenesis.
