1/185. Orthodontic considerations in individuals with down syndrome: a case report.

    The skeletal and soft tissue features, aberrations in dental development, and periodontal and caries characteristics of down syndrome related to orthodontic treatment are discussed. A case report describing the successful orthodontic treatment of a 13-year-old boy with down syndrome and a severe malocclusion is presented. ( info)

2/185. Premature dental eruption: report of case.

    This case report reviews the variability of dental eruption and the possible sequelae. Dental eruption of the permanent teeth in cleft palate children may be variable, with delayed eruption the most common phenomenon. A case of premature dental eruption of a maxillary left first premolar is demonstrated, however, in a five-year-old male. This localized premature dental eruption anomaly was attributed to early extraction of the primary dentition, due to caries. ( info)

3/185. Orthodontic management of mandibular lateral incisor-canine transpositions: reports of cases.

    This article presents different treatment aspects in three mandibular lateral incisor-canine transposition cases. The early identification of transposed teeth simplifies orthodontic correction. Incomplete transposition cases can be managed successfully by interceptive orthodontic treatment. If complete transposition occurs, two treatment alternatives may be possible: Extraction of the transposed tooth or keep the teeth in their transposed positions. ( info)

4/185. root resorption: another long-term outcome.

    Case history is presented of an indigenous Zambian girl. Initial surgical repositioning is shown and at a later stage when the tooth had erupted into the nasolabial vestibule and an orthodontic correction was performed. Surgical trauma as well as orthodontic forces may have precipitated root resorption; however, the aim of saving a tooth has been achieved. ( info)

5/185. Dilacerated incisors and congenitally displaced incisors: three case reports.

    Three cases of dilacerated incisors and congenitally displaced incisors are reported. Dilaceration of central incisors occurs following trauma to the deciduous dentition. Generally these teeth are so severely malformed that they have to be extracted. Congenital displacement of the central incisors is an idiopathic condition with a generally favourable prognosis for orthodontic alignment. ( info)

6/185. Piggyback archwires.

    Commonly, clinicians' principal tool in the alignment phase of orthodontic mechanotherapy is the nickel-titanium wire. During the course of orthodontic treatment, however, there are times when some segments of the dental arch require flexible wires, while the rest would benefit from rigid wires. In this report, we describe a technique where both of these needs are satisfied simultaneously. Specifically, a segment of nickel-titanium wire is piggybacked onto a stainless steel wire in regions where flexibility is desired. This method eliminates the problems associated with the activation, de-activation forces created along a continuous archwire and might be more economical. Clinical pictures illustrate the point.

7/185. Second premolar serial extraction.

    serial extraction of mandibular second premolars should be considered if they are impacted or in cases with moderate arch length deficiency combined with an absence of dentofacial protrusion. The favorable dental changes associated with this approach greatly minimize future orthodontic treatment complexity and time. ( info)

8/185. nasolacrimal duct obstruction secondary to ectopic teeth.

    OBJECTIVE: To describe two patients with nasolacrimal duct obstruction (NLDO) caused by ectopic eruption of teeth. The literature concerning nasal and other unusual ectopic sites of tooth eruption is reviewed. DESIGN: Two interventional case reports and literature review. PARTICIPANTS: A 3-year-old girl with epiphora and recurrent dacryocystitis of the right eye. Previous medical and surgical management was unsuccessful. A 32-year-old female with a long history of right eye discomfort and epiphora. Previous examinations and workup were negative. INTERVENTION: A computed tomographic (CT) scan of the orbits and sinuses was performed in both patients. The ectopic teeth were surgically removed. MAIN OUTCOME MEASURES: Nasolacrimal system function and response to treatment at the last follow-up were recorded. RESULTS: In the first patient, CT imaging disclosed two teeth within the right inferior meatus compressing the nasolacrimal duct. In the second patient, CT revealed a large dental structure in the maxillary sinus compressing the nasolacrimal duct. Endoscopic tooth extraction and nasolacrimal duct probing in the first patient and surgical removal of the dental structure in the second patient effected complete resolution of symptoms. Both patients were symptom free at last follow-up. CONCLUSIONS: These cases suggest that ectopic eruption of teeth should be added to the differential diagnosis of NLDO. Surgical removal of the ectopic teeth compressing the nasolacrimal duct results in resolution of the lacrimal drainage obstruction. ( info)

9/185. Transposition of mesial and distal aspects of maxillary first molars: case report.

    Congenital absence of one or more teeth, hypodontia, is the most common developmental anomaly and is often accompanied by the presence of other tooth anomalies. In this case two Japanese sisters have several congenitally missing primary and permanent teeth and morphological abnormalities of maxillary first molars. One sister has transposition of mesial and distal aspects of a maxillary first molar, whose cusps display a normal shape. Another sister has maxillary first molars, which look like maxillary second molars. Mesio-distally shift of teeth is a very rare anomaly making this particular case important to analyze the teeth formation and development. ( info)

10/185. Ectopic eruption of maxillary canine and premolars: case report.

    This article presents a case of ectopic eruption of permanent teeth in the maxilla in the late mixed dentition. The authors advocate early diagnosis of ectopic eruption with a closer follow-up during the transition from primary to permanent dentition and space maintenance, as a way to avoid active orthodontic treatment for alignment ectopic erupted teeth.
