[Oral and maxillofacial manifestations of familial adenomatosis polyposis. Gardner's syndrome].

Patients suffering from familial adenomatosis polyposis develop multiple pre-malignant gastrointestinal polyps and are at high risk of developing colon cancer. In addition extra-intestinal manifestations are observed frequently. The combination of extra-intestinal manifestations and familial adenomatosis polyposis is named Gardner's syndrome. An early diagnosis of this disease is important because it could mean a better prognosis for the patient. This review describes the oral and maxillofacial symptoms of FAP, and its potential implications for dental treatment.

Mesiodens in the primary dentition stage: a radiographic study.

Five hundred and forty-three Chinese patients in the primary dentition stage were evaluated for mesiodens with maxillary, anterior occlusal films. Compared with other studies, a higher prevalence was found, using different age-groups and diagnostic methods. The distributions of mesiodens by sex, location, and direction were also studied. Because mesiodens could interfere with normal development of the occlusion, especially in the early mixed dentition stage, early diagnosis, using appropriate radiographs during the primary dentition stage, could lead to more comprehensive treatment planning.

Prevalence of hypodontia and hyperdontia in paedodontic and orthodontic patients in Budapest.

Various publications have reported the prevalence of accessory teeth to be between 1 and 3%. In contrast, hypodontia has a much higher prevalence. In the current work, the authors studied OP radiographs on 2,219 patients aged 6 to 18 years who presented at the Department of Paedodontics and Orthodontics at Semmelweis University in Budapest (patients with systemic disease were excluded). The examined radiographs revealed a prevalence of accessory teeth of 1.53%. The sequence of prevalence was as follows: mesiodens > second incisor > first incisor. 77.5% of the accessory teeth were located in the upper jaw, with 97.5% of those being present in the incisor region. Hypodontia was detected in 326 patients (14.69%); missing wisdom germs were not considered. The sequence of prevalence of missing germ was as follows: upper second incisor > lower second premolar > upper second premolar > lower first incisor. Hypodontia in the molar region was observed in 15 cases (0.68%). The prevalence of oligodontia was 1.04%.

[Diagnostic possibilities of digital volume tomography].

Cone beam computed tomography allows high quality 3D images of cranio-facial structures. Although detail resolution is increased, x-ray exposition is reduced compared to classic computer tomography. The volume is analysed in three orthogonal plains, which can be rotated independently without quality loss. Cone beam computed tomography seems to be a less expensive and less x-ray exposing alternative to classic computer tomography.

Rubinstein Taybi syndrome.

Rubinstein Taybi syndrome or Broad Thumb and Hallux syndrome is a genetic multisystem disorder characterized by facial dysmorphism, growth retardation and mental deficiency. A ten-year-old boy who had come to the Department of Pedodontics, Ragas Dental College, Chennai, with the chief complaint of unaesthetic appearance with extra teeth revealed delay in the developmental milestones. The patient appeared to be hyperactive and mentally retarded. Extra oral features revealed distinctive facial appearance with a broad fore head, hypertelorism, broad nasal bridge and beaked nose. Intra oral features observed were talons cusps in the upper central and lateral incisors, mesiodens, carious teeth and plaque accumulation. Since the patient was hyper active and mentally retarded, the dental treatment was done under GA. The treatment plan and dental management of this patient are discussed in this case report.

Dens evaginatus of anterior teeth (talon cusp) associated with other odontogenic anomalies.

Depending on tooth location, usually, dens evaginatus describes an anomaly of posterior teeth and talon cusp as an anomaly of anterior teeth. From the standpoint of developmental, morphological and histological considerations dens evaginatus is a more acceptable term to use and talon cusp should be considered as a subset of dens evaginatus. It mostly occurs as an isolated finding rather than an integral part of any disorder. Two cases of dens evaginatus along with other dental anomalies are reported.

Treatment of a pseudo-class III relationship in the primary dentition: a case history.

In conclusion, posterior and anterior crossbites of the primary dentition should be corrected, once recognized, to allow for normal dental base development and subsequent favorable skeletal growth, provided the analysis of the case reveals no gross boney discrepancies. To quiet any archaic ideas of delaying posterior crossbite correction until the eruption of the permanent first molars, a pilot is being undertaken to determine whether there is a statistical difference in the need for retreatment of patients, when the permanent first molars erupt with the use of either the Porter, Quadhelix, or R.P.E.-type appliances. It is hoped that this will support the low retreatment frequency of 7.6 percent reported by Kutin and Hawes.

[Double teeth in primary dentition and findings of permanent successors].

Prevalence of double teeth in primary dentition of 0.5% was established in the sample of 2.987 preschool children of Zagreb. Between children with double teeth 60% were female and 40% males. Fusion ocurred in 66.7 percent and germination in 33.3 percent in the sample of children having double teeth. In all children with double teeth orthopantomograms were taken. Analysis of radiographs revealed anomalies of permanent successors in 53.3 percent of all children with double primary teeth. In children with germination in primary dentition anomalies of permanent teeth were present in 20 percent (hyperdontia in all cases), while fusion of deciduous teeth was accompanied by abnormal finding (hypodontia) in permanent dentition in 70 percent. Obtained results pointed out to the need of distinction between type of double teeth in primary dentition, i.e. between fusion and germination because chance of lacking the permanent successors is considerably dependent on the type of anomaly.

[Anomalies of deciduous teeth and findings in permanent dentition].

Prevalence of anomalies of deciduous teeth has been analyzed in the general population of Zagreb preschool children. The sample comprised 2,987 children from 3 to 6 years of age (1,582 boys and 1,405 girls). Hypodontia was found in 0.47%, hyperdontia in 0.10%, and double teeth in 0.43% of total sample. Total prevalence of all anomalies in the sample was 1.0%. The sample for the analysis of permanent dentition has been enlarged with the clinical sample of children having the same anomalies and comprised 48 children. In all children with anomalies of primary teeth the orthopantomograms were taken and the status of permanent dentition was analyzed. In children with hypodontia in primary dentition hypodontia of permanent teeth was found in 100% of cases. Patients with hyperdontia of primary teeth displayed anomalies in permanent dentition in 85.7%, while in children with primary double teeth, anomalies of permanent teeth were present in 61.1% of cases. Missing deciduous teeth were found in both jaws in only 8.7% of cases, and in 34.8% in permanent dentition. Symmetrical occurrence of hypodontia of primary teeth (i.e. in both sides of jaws) was significantly higher in boys (56.3%) than in girls (28.6%). In permanent dentition symmetrical occurrence of hypodontia was significantly higher than in primary dentition (81.3% in boys and 57.1% in girls). The most frequently missing primary teeth were maxillary lateral incisors (48.8%) followed by mandibular central incisors (34.9%). Hyperdontia of primary teeth has been found only in boys, and it related only to the maxillary lateral incisors. Anomalies of deciduous teeth show a high degree of association with the finding in the permanent dentition.(ABSTRACT TRUNCATED AT 250 WORDS)

[Osteogenesis imperfecta: presentation of a case].

Osteogenesis Imperfecta constitutes a group of anomalies include between the lethal form of the disease and a condition in which the cortical bone is thiness and more breakable. It's frequently associated to dental abnormalities. It's possible to found serious bone alterations associated to regular dentition or on the contrary. The present article reports a clinical case with Osteogenesis Imperfecta Tarda.

[Comparison of different types of cleft lip and palate in regards to dental anomalies and sexual incidence].

The present study addresses two questions. Does the incidence of dental anomalies differ among the four following types of cleft lip and palate: the isolated cleft palate, the unilateral cleft lip and palate, (right or left), and the bilateral cleft lip and palate. Furthermore is the sexual incidence comparable among the four above mentioned types? Radiographic records and complete family history of clefting of 156 patients with a complete cleft lip and palate were obtained from the Cleft Lip and Palate Teams of Ste-Justine Hospital. Patients in which the cleft was part of a syndrome were excluded from the study. According to the analysis of the data, the incidence of dental anomalies was relatively high, specifically as high as 92% for the bilateral cleft lip and palate. The sexual incidence differed among the four types.
