Management of two unusual cases of dens invaginatus and talon cusp associated with other dental anomalies.

The management of two unusual cases of dens invaginatus and talon cusp is presented. The first concerns talon cusp in maxillary primary and permanent lateral incisors, a supplemental tooth with dens invaginatus hampering eruption of the permanent incisors. The other present with bizarre crown morphology of a lateral incisor with talon cusp, dens invaginatus and a palatal accessory cusp-like structure. Early diagnosis and management are important to avoid complications.

Orthodontic and periodontal considerations in managing teeth exhibiting significant delay in eruption.

AIM: Significant delay in tooth eruption may be observed in many orthodontic patients. This delay may lead to complications, such as devitalization, ankylosis, external root resorption, injury to the adjacent teeth, and mucogingival problems. These complications may result in prolonged treatment time, esthetic deformities, damage to the periodontal tissues, and tooth loss. This report investigates the special considerations needed in treating such cases. METHODS: Combined orthodontic and surgical treatment can be used in managing teeth exhibiting significant delay in eruption. RESULTS: A high rate of success can be achieved in terms of esthetics, occlusion, and periodontal health. CONCLUSION: Nontraumatic surgery, adequate control of gingival inflammation, and use of minimal orthodontic forces may ensure a higher percentage of success and prevention of problems associated with teeth exhibiting significant delay in eruption.

New considerations in the treatment of compromised third molars.

Management of asymptomatic malposed third molars is a controversial topic. As a result, many malposed or mildly pathologic third molars are not removed. Historical pro and con arguments regarding removal centered around cost and the aspects of the surgical removal itself. Current epidemiology and medical advances address issues not considered before. There is a large growth of the aging population (over 40 years). More and more of these elderly patients are requiring third molar removal. Over a five-year period, 1997-2002, the incidence almost doubled to 17.9 percent. This age category is known to be high risk for third molar surgery. An equally or higher risk is the rapidly growing number of patients seeking third molar surgery who are moderately severely medically compromised. This paper reviews how this lack of consensus results in delayed removal of malposed third molars in this population. Preventive dental concepts, removing compromised third molars earlier, would eliminate the high risk to this aging population.

Mixed dentition analysis in a Moroccan population.

The aims of this study were to produce odontometric data for a Moroccan population, to test Tanaka and Johnston and Moyers methods, to derive regression equations and elaborate a specific orthodontic prediction table for Moroccan children. 50 dental casts of Moroccan students (25 males, 25 females, mean age 22.6 years sd 1.35) were used to perform measurements of the greatest mesiodistal widths of all mandibular and maxillary canines and premolars and mandibular incisors with an orthodontic calliper. Significant sexual dimorphism was found in tooth sizes (p = .001). The study revealed close relationships between the total mesiodistal widths of the mandibular permanent incisors and that of the maxillary and mandibular canines and premolars. The correlation coefficients (r) and the coefficient of determination (R2) were better sexes combined for the maxilla (r = 0.60 ; R2 = 0.36 ) and for the mandible (r = 0.61 ; R2= 0.37). The regression equations elaborated for males and females were used as a basis for establishing an orthodontic prediction table for Moroccan children.

Complications of pediatric denture misuse: a case report.

The multiple loss of primary molars due to caries or other reasons in the primary or mixed dentition can lead to severe mutilation of the developing dentition. It is advisable to construct a removable appliance to maintain the relationship of the remaining teeth and to guide the eruption of the developing teeth in order to prevent the child from developing psychological and speech problems. However, parental and patient cooperation are imperative if the pediatric patient is to exercise the necessary care to maintain the denture in a clean and healthy condition. This case report identifies the complications that can arise from the uncontrolled misuse of a pediatric denture. It is concluded that as well as the parents, the pediatric dentists play an important role in the follow-up of the young patients for whom pediatric dentures are constructed. Additionally, patients should be re-called for check-up visits or instructed to refer to the dental clinics in 6-month intervals. Brochures that inform the patients and their parents about the application and care of pediatric dentures and space maintainers should be given.

[Histological study of the resorbed dental crowns of impacted wisdom teeth].

Undecalcified sections of 31 impacted third molars are examined histologically for signs of resorption. Resorption starts at small spots in enamel, progresses to dentin and may even penetrate the pulp cavity. The incidence of such resorption processes increases after the age fifty. A prerequisite for resorption is the loss of reduced ameloblastic epithelium. Histological examination reveals multinuclear giant cells and apposition of spongious bone to destroyed dental substances. The results is dental ankylosis. Because partially resorbed teeth or ankylosed teeth may lead to serious surgical difficulties, impacted wisdom teeth without any clinical symptoms and without pathologic radiological findings should always be extracted at a young age.

A retrospective assessment of zinc oxide-eugenol pulpectomies in vital maxillary primary incisors successfully restored with composite resin crowns.

PURPOSE: The purpose of this retrospective study was to evaluate, via clinical and radiographic assessments, the treatment outcome of zinc oxide-eugenol (ZOE) pulpectomies performed in vital maxillary primary incisors successfully restored with composite resin crowns. METHODS: Pulpectomized vital primary incisors were treated by a uniformed technique, filled with ZOE paste, and successfully restored with composite resin crowns. Those that remained intact and noncarious for the assessment interval were evaluated for the outcome (success or failure) based on clinical and radiographic findings and compared to: (1) the reason for treatment; (2) the canal filling extent; (3) the type of composite resin crown restoration performed; and (4) the eruption status of its succedaneous tooth. RESULTS: For 104 maxillary primary incisors meeting the inclusion criteria, failure, as judged by presence of pathologic root resorption and/or apical lucency, was determined to be 24% (25/104), for a mean duration of 18 months observation. Failures were statistically associated with the reason for treatment (higher for trauma), the extent of ZOE paste filler in the pulp canal (higher for gross overfill), and the eruption status of the associated succedaneous permanent incisor (higher for delayed eruption). CONCLUSIONS: This study determined a failure rate (24%) for pulpectomies-using ZOE paste and performed on vital primary incisors-comparable to that reported for nonvital pulpectomies. A statistically significant increase in failure rates was found for: (1) incisors treated for trauma (42%) vs those treated for dental caries (19%); and (2) grossly overfilled canals (80%) vs canals filled to the apex (0%).

Supernumerary teeth and mental retardation: the importance of early surgical intervention.

AIM: This paper reported a rare case of hyperdontia in a child of 10 years who revealed a mixed dentition and a light mental retardation. MATERIALS AND METHODS: The therapeutic approach has been based on interdisciplinary cooperation between the pediatric dentist, orthodontist and oral surgeon. TC-Dentascan, with a panoramic and occlusal radiographs revealed the presence of two supernumerary teeth in the premaxillary region and clinical examination showed an abnormality of dentoalveolar complex. Both impacted supernumerary teeth were extracted under general anesthesia. Clinical examination revealed that they appeared two premolars in shape with fully formed crowns and partly formed roots. RESULTS: Three months after the extraction of supernumerary teeth there was a spontaneous eruption of permanent central incisors and left lateral incisor. CONCLUSION: The authors emphasized the importance of removal of supernumerary teeth to eliminate the cause of a delayed eruption of permanent teeth.

Cleidocranial dysplasia: 2 generations of management.

Patients with cleidocranial dysplasia (CCD) commonly present with significant dental problems, such as retention of multiple deciduous teeth, impaction or delay in eruption of permanent teeth and, often, the presence of supernumerary teeth. Several approaches have been described for the management of such patients. We report 2 cases illustrating the shift in the management paradigm from edentulation and prosthetic replacement to orthodontically assisted forced eruption and fixed appliance orthodontic treatment combined with orthognathic surgery.
