Objectives:
The main objective of this study was to report the prevalence and other relative risk factors of oral clefts among newborn infants.
Methods:
In this study, we reviewed the data regarding 234 infants with cleft anomalies as collected in questionnaires from 2004 to 2019 and demographic parameters were assessed.
Results:
Cleft lip and palate was the most common anomaly (66.7%), followed by isolated cleft palate (28.2%), isolated cleft lip (3.8%), and cleft lip and alveolus (1.3%). The study also showed that 54.3% of all cleft patients were boys and 45.7% were girls (with a rate of 1.18) and the difference between both sexes was significant (P-value = 0.010). In addition, cleft lip and palate was more common in males and isolated cleft palate was seen more in girls (P-value = 0.002, P-value = 0.001, respectively). The parents (56.4%) had consanguinity and 20% of them had a history of cleft in their family.
Conclusion:
Cleft lip and palate in boys and cleft palate in girls was more common. Parents' consanguinity and history of cleft in their family are also important factors to consider. Further studies on cleft anomalies along with or without genetic factors are required.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Oral Cavity
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
