Hypohidrotic ectodermal dysplasia: dental, clinical, genetic and dermatoglyphic findings of three cases.

Patients with hypohidrotic ectodermal dysplasia (HED) are characterized by the clinical manifestations of hypodontia, hypohidrosis, hypotrichosis and a highly characteristic facial physiognomy. This disorder is inherited as an X-linked trait. This report presents three cases with HED in which the clinical evaluation (intraoral and radiological), genetic findings and SEM examination of hair.

The relation of bruxism and dermatoglyphics.

With the aim to examine the dermatoglyphic patterns of finger and palm, 38 bruxism patients, 18 being female were studied. Fingerprint patterns in bruxism has previously been discussed in a few papers, but this is the first paper about dermatoglyphic patterns of palm in bruxism. The aim of this study of finger and palm prints in patients with bruxism were to discuss the importance of dermatoglyphic patterns in the diagnosis and etiology of the disease.

The dental, genetic, radiological and dermatoglyphic findings of a 19-year-old girl showing macrodontia of maxillary permanent central incisors in association with a contrasting character, microdontia of maxillary permanent lateral and mandibular primary central incisors and bilateral absence of maxillary first premolars and missing of the right mandibular second premolar and peg-shaped mandibular primary lateral incisors and canines were presented.

A Rapp-Hodgkin like syndrome in three sibs: clinical, dental and dermatoglyphic study.

Rapp-Hodgkin ectodermal dysplasia is an autosomal dominant disorder characterized by distinctive craniofacies, cleft lip or palate, oligodontia or anodontia, hypoplasia of the nails, and a decrease in or absence of the sweat glands and hair follicles. We have identified a family in which three children display clinical features similar to Rapp-Hodgkin syndrome. The father and two other sisters of the patient had normal facial features, but had short stature and had dental anomalies, the latter suggestive of ectodermal dysplasia.

Taurodontism in association with supernumerary teeth.

The dental, radiological, genetic and dermatoglyphic findings of an additional patient with taurodontism in association with supernumerary teeth were presented and the findings of the patient were compared with those in the literature.

Inverted impaction of a mesiodens: a case report.

Dental, radiological, dermatoglyphic and genetic findings of a patient showing inverted impaction of a mesiodens are presented. It is probable that the inversion of the mesiodens was caused by contact of the incisal edge of the crown of the mesiodens by the apex of the root of the erupting right maxillary central incisor tooth.

Hypocalcification type amelogenesis imperfecta in permanent dentition in association with heavily worn primary teeth, gingival hyperplasia, hypodontia and impacted teeth.

A female patient with hypocalcification type amelogenesis imperfecta in permanent dentition in association with heavily worn primary teeth, gingival hyperplasia, hypodontia and impacted teeth is presented.

Hemifacial microsomia: oral, clinical, genetic and dermatoglyphic findings.

Oral, clinical, genetic and dermatoglyphic findings of a female patient with hemifacial microsomia are described and compared with those cited in the literature.

Dermatoglyphic findings in dental caries: a preliminary report.

The dermatoglyphs of caries-free students and the students with dental caries in 10 or more teeth were compared. The caries-free students had an increased frequency of ulnar loops on all fingers. In contrast, the students with dental caries had an increased frequency of whorls on all fingers.

Enamel hypoplasia and essential staining of teeth from erythroblastosis fetalis.

The dental, clinical, radiological, pedigree and dermatoglyphic findings of a patient showing hypoplasia of enamel and intrinsic staining of the teeth from erythroblastosis fetalis are presented.

Congenital hypodontia of maxillary lateral incisors in association with coloboma of the iris and hypomaturation type of amelogenesis imperfecta in a large kindred.

The dental, clinical, genetic, radiological and dermatoglyphic findings in patients from a large kindred with congenital hypodontia of maxillary lateral incisors (CHMLI) in association with coloboma of the iris (Cl) and hypomaturation type of amelogenesis imperfecta (HTAI) are presented. The pedigree of the kindred showing multiple consanguinaeous marriages and the findings of the family members with CHMLI and a family member with CHMLI, Cl and HTAI and two members with both CHMLI and HTAI suggested that the isolated CHMLI was due to an autosomal recessive gene, but, the Cl was determined by an autosomal dominant gene linked to CHMLI gene. HTAI was an autosomal recessive character linked to both CHMLI and Cl.

Dermatoglyphics in patients with Cenani-Lenz type syndactyly: studies in a new case.

We describe an additional case of Cenani-Lenz syndactylism in a 4 1/2-year-old boy from a consanguineous Turkish family. The digital anomalies consisted partly of synostosis and partly of malformations of the phalanges. Although there was no radio-ulnar synostosis or abnormality of the bones of the feet, the findings are comparable to those described in the Cenani-Lenz type of syndactyly.

Local, hypoplastic type of amelogenesis imperfecta: a clinical, genetic, radiological and dermatoglyphic study.

A patient and her family members showing X-linked dominant form local, hypoplastic type of amelogenesis imperfecta (AI) were investigated from view-point of their teeth, clinical, genetic, radiological and particularly dermatoglyphic findings. It was suggested that it might be a close relationship between the intra-uterine development of both AI and unusual dermatoglyphs originated from the same layer, ectoderm and an X-linked dominant gene could determine both abnormal teeth and unusual dermatoglyphic characteristics in questions.

The clinical, genetic, radiological and dermatoglyphic findings of a case showing generalized microdontia associated with an extra maxillary central incisor, hypoplastic maxilla, prognathic mandible, wide-set of the ears, hooked nose, astigmatism, camptodactyly, flexion contractures of the distal interphalangeal joints of the fingers, thinning of the fingers towards the distal end of the palm, and complete webbing of the IVth and Vth toes (syndactyly type III) and short stature were presented.

Congenital hypodontia: a pedigree and dermatoglyphic study.

The dermatoglyphs and the pedigrees of 11 male and 10 female, a total of 21 patients with congenital hypodontia (CH) were investigated. The dermatoglyphics of the patients were compared with those of 250 male and 250 female control cases. There were more arches on the finger-tips of the patients with absence of the lateral incisors, absence of the second premolars and a total patients with CH.

Bilateral absence of maxillary and mandibular second premolars: a clinical, genetic and dermatoglyphic study.

In the report presented here the mode of inheritance pattern of absence of maxillary and mandibular second premolars will be investigated by pedigree analyses and dermatoglyphic studies of a patient who showed the trait and his family members. An 11-year-old male patient with caries with bilateral absence of maxillary and mandibular second premolars was observed. Most of the dermatoglyphic traits observed in the patient were also found in the father and the sister of the patient.

A genetic and dermatoglyphic study on periodontitis.

Periodontal diseases encompass a wide range of disease manifestations and processes from the mildest inflammation of gingiva to the most advanced destructive periodontitis with loss of attachment, bone tissue and teeth. No entirely satisfactory identification and classification exist in periodontitis especially for high risk early onset periodontitis (EOP) cases, because of insufficient knowledge about the aetiological and host factors and their overlapping clinical and laboratory features. In this study, the dermatoglyphics, which is a genetic test method, suggesting the modes of inheritances of hereditary diseases, was performed on 36 EOP and 20 adult periodontitis (AP) patients and 20 periodontally healthy individuals.

Robinow syndrome: with special emphasis on dermatoglyphics and hand malformations (split hand).

Fourteen cases of Robinow syndrome are described with special emphasis on dermatoglyphics and hand malformations (split hands were detected in two, ectrodactyly with nail hypoplasia in one and hypoplastic extra middle finger in another one). Dermatoglyphic studies were performed on ten cases. Increased whorl patterns of the finger tips and a single large palmar hypothenar whorl pattern associated with distally displaced axial triradii were detected.
