Options in aesthetic restorations: discoloration and malformation--problems and solutions.
This article is a review of the current options for treatment of discolored and malformed dentition--laminate veneers, all-ceramic crowns, and metal-ceramic crowns. It emphasizes the importance of close cooperation between the restorative dentist and the laboratory technician and a thorough knowledge of the dental materials science. The objective of this article is to provide diverse solutions for severe tooth discolorations and malformations. Four cases illustrate the procedures, the materials utilized, and the results achieved.
[Chemotherapy and dental growth].
A prospective study about the development of the mandibular second right molar, has been performed with 17 chemotherapy treated children in the Paediatric Oncology department of the Centre Oscar-Lambret (Lille). Our method is based upon the measure of the crown or root length for different periods: periods with or without chemotherapy. These measurements have been performed every 6 months for 18 months with orthopantomograms. We notice for both the crown and the root: a significant difference in growing speed between periods with an without chemotherapy; a speeding up of the mineralization at the end of the treatment rejoining the average figures of a healthy test population.
Enamel opacities and dental caries in children who used a low fluoride toothpaste between 2 and 5 years of age.
A recent clinical trial investigated the cariostatic effectiveness of a low (550 ppm) fluoride toothpaste in comparison with a standard (1050 ppm) control paste in pre-school children who were 2-years-old at the start of the 3-year trial. The present study has investigated the prevalence of enamel opacities in permanent incisor teeth and of caries in children who had taken part. As well as children from test and control groups, a third group of non-trial children were included in the sample. A total of 1,523 children were examined in schools and had photographs taken of their upper permanent incisor teeth. The latter were scored using the Thylstrup and Fejerskov (TF) index for fluorosis and the modified Developmental Defects of Enamel (DDE) index. Differences between the groups were small in real terms but using the TF index the child and tooth prevalence of opacities were significantly lower in the children who had used the test paste with a lower fluoride content; the same trend was seen in diffuse defects scored using the modified DDE index. There was no significant difference in the prevalence of caries in either primary or permanent teeth although the trend in both cases was for slightly more disease in children who had used the test paste.
[Cleidocranial dysplasia: review of the literature and presentation of a case].
Cleidocranial Dysplasia, although not frequent, can present to the dentist. In this article, we have reviewed the literature concerning this disease and we present a patient with this condition. An overview of the disease would reveal partial to complete absence of clavicles, delayed closing of cranial fontanels, prolonged retention of deciduous teeth, subsequent delay in eruption of permanent teeth and multiple impactions.

Multiple dens evaginatus: diagnosis, management, and complications: case report.
Dens evaginatus is a disturbance in tooth formation that appears clinically as an accessory occlusal tuberculated cusp composed of enamel and dentin, usually enclosing pulp tissue. The tubercle often fractures or is worn away, with subsequent pulp exposure leading to pulpal inflammation, necrosis, and periapical inflammation. When this happens to an immature tooth, diagnosis may be complicated by the similarity in radiographic appearance of the periapical lesion and the dental follicle. The management of such teeth may be complicated because of their immaturity. A case report of multiple abraded dens evaginatus with pulp necrosis is presented that illustrates 1) the difficulty of diagnosing otherwise apparently healthy teeth associated with periapical lesions and sinus tracts, and 2) their management and treatment complications including recurrent infections and root fractures.

Evaluation of occlusion, trauma, and dental anomalies in African-American children of metropolitan Headstart programs.
493 African-American children between the ages of three and four years were examined for evaluation of molar occlusion with frequency of anterior and posterior crossbite, fractured and/or darkened teeth from trauma and dental anomalies in the primary dentition. Overall results from both age groups revealed 90% had a mesial step, 8% a flush and 2% a distal step molar occlusion. Crossbite, either anterior or posterior, occurred in 12% of all children examined. Posterior crossbite was seen in 7% and anterior crossbite in 5%. Anterior openbite was seen in 8% of the children. Trauma to the primary dentition occurred in 23% of the children, 16% as fractured and 7% as discolored teeth. The most frequently involved teeth were the maxillary primary central incisors. Fused primary teeth were observed in two children. There were no congenitally missing primary teeth and only one supernumerary maxillary primary lateral incisor was observed.
Maintenance care and supportive periodontal therapy.
This paper presents a review of the literature and clinical observations concerning the long-term professional care of all dental patients. Gingivitis, ubiquitous in the adult population, is often without significant consequences to the dentition; however, gingivitis may develop into periodontitis. Patients with gingivitis, therefore, should be monitored professionally, especially those patients with other risk factors (attachment loss, age, smoking, and abnormal tooth mobility). In patients without substantial attachment loss, professional examination, prophylaxis, and oral hygiene instruction should be provided once or twice a year, depending on the presence of other risk factors. All patients who have been treated for periodontitis should be recalled, after completion of treatment and a healing phase, every 3 to 4 months. Sites with active periodontitis should be re-treated. Topical use of fluorides is recommended.
Oral-facial characteristics of circumscribed scleroderma: case report.
Scleroderma is a rare disorder of unknown etiology. Circumscribed scleroderma is a localized focal form. It may present as well defined elevated or depressed white or yellowish patches termed "morphea," or linear bands made up of a furrow with elevated ridges on the margins described as "coup de sabre." The oral-facial characteristics of circumscribed scleroderma in a ten year old afflicted female are described in detail.
Incontinentia pigmenti (Bloch-Sulzberger syndrome): a case report.
A syndrome--incontinentia pigmenti--of probable genetic etiology, is discussed and a new case report presented. The syndrome presents systemic and dental manifestations, which are separate although similar to those found in other disease entities, i.e., congenital syphilis, hereditary ectodermal dysplasia.
Surgical management of the palato-radicular groove and associated periodontal lesion: a case presentation.
The palato-radicular groove is an anatomic variant which may be associated with significant attachment loss. This article illustrates the need to carefully examine all patients for the presence of such an anomaly and suggests one possible treatment modality in the event an associated periodontal lesion is present. The learning objective of this article is the ability to recognize this anatomic anomaly and to implement corrective measures.
