Context: Cleft lip and palate (CLP) is the most common congenital malformations in the face and neck. Given that the inheritance of this disease is multifactorial and both genetic and environmental factors play crucial roles in its creation, studying these factors may be a step toward reducing the prevalence of the disease in future generations. Method: For this study, we looked through several national and international databases, consisting of Scientific Information Database, IranDoc, ScienceDirect, Google Scholar, PubMed, and Scopus. Based on our search method, we found 800 published articles, of which 750 were obtained from the international databases, and the remaining 50 were extracted from the national databases. After data refining, 600 articles with eligible criteria remained for data extraction, and data related to embryological origin, classification and etiology, genes and environmental factors, and complications caused by CLP were collected. Results: The CLP etiology was multifactorial and involved both genetic and environmental risk factors. The primary purpose of this review was to give the reader an overview of studies on multifactorial causes of this congenital disability. The functions of genes are very different, indicating a high level of vulnerability in the cranial and facial growth pathways. Conclusions: These findings have advanced our understanding of genes associated with CLP and genetic polymorphisms involved in orofacial closure defects. The findings can create new clinical and molecular research opportunities.

X-ray cephalometry was used in studies of facial growth and development carried out in 32 males with complete unilateral cleft lip and palate. They underwent primary periosteoplasty and were examined at the ages of 10 and 15 years. The results were compared with the development of the face In a longitudinal study of 20 males with the same type of cleft who were operated with a primary bone graft. The series with periosteoplasty showed a more marked proclination of the upper dentoalveolar component with the restoration of a positive overjet, as compared to a persistent anterior crossbite in the males with bone grafts. The lower jaw showed a larger protrusion, while individuals with bone grafts were characterized at the ages of 10 and 15 years by a larger posterior rotation of the mandible. The growth of the maxilla did not differ between series. In both series, there was a marked reduction In the growth of maxillary depth and of upper lip height, while the highest growth rate showed parameters of nasal prominence. An increasing mandibular protrusion and maxillary retrusion resulted in an impairment of sagittal jaw relations and in the flattening of the face, both of which occurred in almost all patients. The rotation of the lower jaw was not correlated with either the convexity of the face, sagittal jaw relations, or an overjet. The independence of developmental changes of selected characteristics at their initial state documented the impossibility of predicting the development of the face on the basis of a single x-ray examination at a given stage of development. Fixed appliances promoted a more marked proclination of upper incisors and the alveolar process than removable appliances, but they exerted no direct action on the other facial parameters studied.

This article reviews the concepts associated with dermatoglyphs such as their classification, characteristics and applications. It also reviews orofacial clefts such as cleft lip and palate and proposes a possible relationship between dermatoglyphics and these orofacial clefts, entities that are considered isolated at first, but considering that they are derived from the same embryonic tissue, the ectoderm, and their development is in the same period of gestation, making genetic and environmental factors that would influence the development of the asyndromic lip and / or palate could be reflected in the fingerprints and the type of pattern that they follow. Key words: Cleft lip, dermatoglyphics, cleft palate, fingerprint.

Objective To assess the skeletal and dental craniofacial proportions of unilateral cleft lip and palate patients who were operated upon using the Malek technique, and compare them with a normal group to highlight the effect of surgical correction on craniofacial development during growth. Design Retrospective. Methods The cleft palate was closed using the Malek technique in a single operation at 3 months for 11 patients (complete closure of lip and palate) and in a two-stage operation for 10 patients (soft palate at 3 months, lip and hard palate at 6 months). Comparisons were made with a normal control group. Angular and linear measurements of anterior and posterior dimensions of the upper and lower compartments of the face were measured in the 7th and 12th years. Results and Conclusion No significant differences were observed between the two groups of palate technique repair, although significant differences were observed between craniofacial dimensions of normal versus cleft lip and palate patients. At a skeletal level, the maxilla and mandible were retrusive relative to the cranial base in the cleft lip and palate group. In fact, there was a backward rotation of the palatal plane with repercussions on the maxillo-mandibular complex position. Furthermore, the maxilla was shorter than in normal patients, whereas the mandible was normally shaped. The upper incisors were retroclined and they locked the lower incisors in linguoversion. There was a posterior skeletal deficit of the respiratory compartment, compensated by more marked posterior maxillary alveolar growth. Facial growth in cleft lip and palate patients followed the same pattern, but was delayed compared with normal patients.

This report is a serial growth study of a pair of monozygotic twin boys, one of whom suffered from a bilateral cleft of the lip and a unilateral cleft of the palate. Annual records for height and weight were registered from seven years eight months to 18 years 0 months. Soft tissue facial growth was also measured annually using short base stereophotogrammetry (Burke, 1967). Growth and development of the dentition was recorded as orthodontic study models at less frequent intervals. Measurements derived from the facial maps allowed not only measurement of soft tissue growth changes in the face, but also of surgical change to both lips related to an Abbe flap procedure carried out for the cleft twin. All changes are compared with those occurring in his monozygotic twin.

Relevance. Cleft lip and palate is one of the severe malformations of the face and jaw, requiring a comprehensive approach to the rehabilitation of the patients, including doctors of various specialties, one of which is orthodontists. A feature of orthodontic treatment is difficulty of fixing bracket systems, as well as lowering the level of oral hygiene, caused by deformation and displacement of fragments of the maxillofacial region.Purpose. Improving the effectiveness of orthodontic treatment and hygiene of the oral caviti in patients with cleft lip and palate in permanent bite period.Materials and methods. A comparison was made of the effetctiveness of fixing brackets systmes with direct and indirect bonding techniques and the effectiveness of oral hygiene during orthodontic treatment using irrigators.Results. The results of the study showed a difference in the effectiveness of using direct and indirect methods of fixing bracket systems in patients with cleft and palate. The use of irrigators as additional means of oral hygiene has demonstrated a positive dynamic of hygiene indices.Conclusions. Results of the study demonstrate the advantages of fixation the brackets by indirect bonding and use additional hygiene products irrigator for improving of oral hygiene.

Orofacial clefts (OFC) are one of the most common congenital problems seen with a very high incidence. It imparts a negative effect on the overall health of the child by hindering in his feeding practices, normal facial growth, development of dentition and hence speech. Infants born with orofacial clefts have oronasal communication which creates a problem with the creation of negative pressure inside the oral cavity required for suckling.The treatment for such patients is with the multidisciplinary approach but the preliminary  concern for the neonate is to help with the feeding for which a feeding appliance is given. This case report presents a case of a 3-day old infant to whom a feeding appliance was given to aid in suckling.

The normal development of the face relies upon the correct morphogenesis of structures in utero that usually occurs within the first trimester of embryonic life. The face is a very complex structure involving many genes and factors and with it being such a crucial part of life, both physically and aesthetically and therefore mentally, its important for everything to be just right. However, when the normal process doesn’t go to plan this results in dysmorphogenesis, which cleft lip and palate (CLP) is an example of as the lip/palate doesn’t fuse together and the infant is left with a gap. Although the exact cause of CLP is unknown, it is thought to be a mixture of genetics, environment and the teratogens the mothers are exposed to within the environment. This report will demonstrate the normal development of the face for the purpose of understanding how it goes wrong, resulting in CLP. Since there is still a lot to be understood about CLP it will also shed light on recent advances in relating SHH and certain genes as a possible cause for this dysmorphogenesis. The report will also briefly look at the relation of CLP with the genes associated with syndromic and non-syndromic diseases and the different types of CLP. There are many other facial defects that are a result of dysmorphogenesis, however as CLP is one of the most common yet poorly understood facial defect, it will be the main focus of this report.
