Clinical features of incontinentia pigmenti with emphasis on dermatoglyphic findings.

Incontinentia pigmenti is a syndrome characterized by both systemic and oral manifestations. Presented here are the dental, clinical, radiological, genetic and dermatoglyphic findings of a 6 year old female case and her family members. The following features were apparent: oligodontia in maxillary and mandibular arches in both dentition, peg-shaped incisors and brown lesions on the body surface. No other problems were observed. The case had remarkable dermatoglyphic findings such as hypothenar loops associated with distally displaced axial triradii on both palms, reduced total finger and summed palmar a-b ridge-counts, decreasing plantar pattern intensity on the left sole. The other family members had similar dermatoglyphic characteristics. The paternal grand father, the father and the brother had eye defects.

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. Boys 6 to 14 year old and a 11 year old girl were referred to the Marmara University, Faculty of Dentistry, complaining of oligodontia in the maxillary and mandibular arches and delay in eruption of other teeth. Peg-shaped teeth have been observed. The dermatoglyphs of the patients were striking. SEM examination of hair demonstrated a distinctly abnormal longitudinal grooving along the entire length of each hair and a desquamation of the surface cuticles. The treatment was planned in a multidisciplinary odontological group involving pediatric dentistry, orthodontics, prosthodontics and oral surgery and maxillofacial radiology of future dental habilitation. A specially designed overdenture, a removable prosthesis and osseointegrated implants were constructed. Periodic recall visits were advised, to monitor the dentures and implants during periods of growth and development, and eruption of the permanent teeth.

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. Bruxism patients demonstrated an increase in frequency of whorls and a decrease in frequency of ulnar loops than the controls. Patients with bruxism demonstrated a lower frequency of atd angle than controls. Augmentation of I loops and t triradii and diminution of IV, H and t" triradii were observed in bruxism patients. Furthermore, the main line A ended more frequently in sector 5' in bruxism patients when compared with controls. There is no significant difference between the total finger ridge counts (TRC) and a-b ridge counts the subjects with bruxism and that of the controls. The dermatoglyphic patterns of finger and palm was significantly different in children with bruxism. When combined with other clinical features in bruxism, dermatoglyphics can serve to strengthen a diagnostic impression.

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.

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. The overall clinical, dental, and dermatoglyphic findings of these patients are discussed in relation to reports of families with Rapp-Hodgkin syndrome.

Macrodontia in association with a contrasting character microdontia.

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.

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.

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. We analysed the dermatoglyphics of our patient and compared them with those previously reported. We also investigated the relationship between the bony malformations and the dermatoglyphic patterns in our patient and in the literature.

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.

Generalized microdontia and associated anomalies: a clinical, genetic, radiologic and dermatoglyphic study.

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.
