Eruption of rootless teeth in congenital renal disease

Eruption of rootless mandibular premolars and other dental defects in a girl suffering from congenital kidney disease are described. The successful management of these excessively mobile teeth allowed them to develop roots of sufficient length. Hypotheses of tooth emergence are viewed in the light of these rootless eruptions.

Marginal adaptation of glass-ionomer cements.

The effect of thermocycling on the marginal adaptation of two glass-ionomer cements was determined by means of scanning electron microscopy. Small gaps in the cement as well as at the enamel-cement interface were observed after curing, but these phenomena were not enhanced by thermocycling. Localized areas of surface deterioration were observed for both cements after thermocycling.

Teaching and practical guidelines in pulp therapy in primary teeth in Colombia – South America

OBJECTIVE To describe the teaching practical guidelines in pulp therapy for primary teeth in Colombian dental schools, based on Primosch et al. survey (1997). METHODS A 27-question survey was sent to 31 dental schools. A total of 68 surveys were obtained for analysis of the results, in which pediatric dentists answered 48 surveys, 11 surveys by general practitioners, and 9 were answered but were not identified in any of these groups. RESULTS Indirect pulp treatment (IPT) is taught by pediatric dentists (83%) and general practitioners (90%). Calcium hydroxide and glass ionomer were the preferred materials in this treatment. Pulpotomy is the most commonly procedure used. There was no different percentage in the use of medicaments: cresatin, glutaraldehyde, calcium hydroxide, formocresol. Pulpectomy is taught by general practitioners (73%) and pediatric dentists (96%). The preferred filler material, used by general practitioners (73%) and pediatric dentists (94%), was zinc oxide and eugenol. CONCLUSIONS There is a discrepancy in the choice of treatment and medications for pulp therapy primary teeth between general practitioners and pediatric dentists. The recommendations given in American Academy of Pediatric Dentistry (AAPD) guidelines 2012 for pulp therapy in primary and young permanent teeth are being followed in the majority instances.

Acid-etch/composite resin restoration of fractured anterior teeth

R epair of fractured incisal angles of anterior teeth has always been a difficult procedure, particularly when done for children. Retention and esthetics are problems and a variety of procedures have been proposed, none of them fulfilling the requirements of an ideal restoration. Thus, a more esthetic restoration, such as a complete veneer crown, involves radical tissue removal which jeopardizes the vitality of the young pulp. Presently, there is no material capable of forming an adhesive bond with an untreated enamel surface under oral conditions. Several reports have indicated that satisfactory retention can be achieved after etching of the enamel surface.l-+’ Several modifications of this technique have been reported. 5-10 Different restorative materials have been applied to the etched area, among them filled and unfilled resins. Ward, Buonocore, and Woolridge I1 described the use of a restorative material in conjunction with a fissure sealant, which was polymerized by ultraviolet light. The resin functioned as a bonding medium between the tooth and the composite material, and these authors claimed that the result was increased retention of the restoration.12, I3 Barbakow and associates14 report a clinical study in which fractured incisal edges and other hypoplastic lesions were successfully restored with Restodent.? This investigation evaluated retention and the esthetic results of acid-etched Restodent restorations placed on fractured permanent anterior teeth.

Pulp Therapy for the Primary Dentition

Several treatment options for pulp therapy in primary teeth are reviewed. Conservative treatments are recommended for primary teeth whose pulps have the potential to recover once the irritation has been removed. The role of dentin permeability and microleakage is emphasized when protective basis and indirect pulp treatment are discussed. Alternative dressings for formocresol pulpotomies such as 6.25% glutaraldehyde solution, antigen-extracted allogeneic dentin matrix, and crude bone morphogenetic protein are reported with promising results. Pulpectomy is recommended for teeth with evidence of chronic inflammation involving radicular pulp or pulp necrosis with and without periapical involvement. The main disadvantage of zinc oxide-eugenol paste, widely used for primary root fillings in the United States, is its slow resorption rate, frequently much slower than that of the root. Other root canal pastes containing iodoform, or a modification of this with the addition of calcium hydroxide, are being utilized in South America, Japan, and Europe.

Pulpotomy Techniques: Cervical (Traditional) and Partial

The conservation of primary teeth in form and function until their normal exfoliation is one of the fundamental objectives of pediatric dentistry. Not only is it important for normal speech, development, and self-esteem, it is the best way to preserve arch length and avoid secondary issues such as space loss and permanent tooth impaction.

The Primary Pulp: Developmental and Biomedical Background

Maintaining the integrity and health of the oral tissues is the primary objective of pulp treatment. Premature loss of primary teeth can lead to malocclusion and/or to esthetic, phonetic, or functional problems. It is important to attempt to preserve pulp vitality whenever possible; however, when this is not feasible, the pulp can be entirely extirpated without significantly compromising the function of the tooth [1, 2].

Pediatric Endodontics: Past and Present Perspectives and Future Directions

Dentistry for children is one of the most needed of all specialties in dentistry. Yet, unawareness of newer concepts of present-day pediatric dentistry practice and the ultimate goals to be achieved still exist. The value of teaching pediatric dentistry cannot be overestimated as inadequate or unsatisfactory dental treatment during childhood may damage permanently the entire masticatory apparatus, leaving the individual with many of the dental problems so common in today’s adult population [1].

Pink Spot – Literature Review and Case Report

BACKGROUND Pink spots in teeth were first described by Mummery in 1920, and were related to resorption. Resorption is a pathologic process that often eludes the clinician with its varied etiologic factors and diverse clinical presentations. Resorption can be generally classified as internal and external resorption. Internal resorption has been described as a rare occurrence as compared to external resorption. CASE REPORT This article describes a pink spot that was diagnosed as a progressing resorption process. Early diagnosis enabled a successful management of the lesion. CONCLUSION Early diagnosis and treatment of an internal resorption, clinically seen as a pink spot, in a primary central incisor may prevent its fast progress and subsequent loss.
