Prevalence of dentofacial characteristics in a belgian orthodontic population.

The aim of this retrospective study was to provide quantitative information on the prevalence of dentofacial characteristics to find correlations between them and to determine the orthodontic treatment need in a Belgian orthodontic population. Data were acquired from 1,477 patients who had initial records made at the Department of Orthodontics, Katholieke Universiteit Leuven, Belgium between February 1983 and June 1997. The prevalence of Angle Class I, Class II div. 1, Class II div. 2 and Class III malocclusions was, respectively, 31%, 52%, 11% and 6%. The male-to-female ratio was 4:6. Spacing and trauma to teeth occurred more in males than in females. The prevalence of the following dentofacial characteristics was significantly different between the Angle classes: segmental crossbite; crossbite of one tooth; facial asymmetry; protral and lateral mandibular shift; horizontal and vertical growth patterns, impacted teeth; traumatised teeth; ectopically erupting canines; age at first records. No significant difference in the prevalence of the Angle classes between the sexes was found. Several clinically relevant correlations were found between the examined dentofacial characteristics. This Belgian orthodontic population from the Leuven region seems to be comparable to other orthodontic populations in Europe.

Ectopic soft-tissue mesiodens.

The mesiodens is the most common supernumerary tooth. It can be found in both the erupted and the impacted states. A case of a developing mesiodens located entirely in soft tissue is described. The lesion presented as a pedunculated palatal mass. No case of soft-tissue mesiodens has been previously reported. A theory of origin for this supernumerary tooth is proposed.

Supernumerary tooth in the maxillary sinus: case report.

The ectopic development of teeth has been reported in many locations including the nasal cavity, maxillary sinus and the chin. Ectopic teeth may be permanent, deciduous or supernumerary. A case is presented in which a supernumerary tooth erupted into the maxillary sinus of an 11 year old boy.

Intrusion injuries of primary incisors. Part II: Sequelae affecting the intruded primary incisors.

Luxation injuries to incisors, including intrusive displacement, occur with a high frequency in the primary dentition. Intrusion injuries are associated with damage to the pulpal and periodontal structures and possible fracture of the alveolar bone. The pulpal tissue of the intruded tooth sustains a severe shock during displacement, which may be reflected later by sequelae ranging from mild discoloration to pulpal necrosis and infection. Disintegration of pulpal tissue may result in periapical tissue inflammation, which in turn may induce developmental disturbances in the germ of the permanent successor tooth. Additionally, severe injury to the periodontal ligament during intrusion may lead to ankylosis of the primary incisor and consequently to delayed or ectopic eruption of its permanent successor. This article will review the possible sequelae affecting primary incisors following their intrusion.

Treatment of ectopically erupting maxillary permanent first molars with a distal extended stainless steel crown.

The exaggerated mesial eruption of the permanent first molar can result in the tooth becoming impacted, or the premature atypical resorption and exfoliation of the primary molar, with a resultant loss of space. A stainless steel crown with a distal guide plane was placed on a primary molar to correct the aberrant eruption angle of the permanent tooth. This procedure can be used successfully for both partially and totally tissue-impacted teeth, and is described in this report.
