Glass-ionomer-resin restoration of primary molars with adjacent Class II carious lesions.

Glass-ionomer-resin cements carry the advantages of both traditional glass-ionomer cements (such as esthetics and fluoride ion leaching) and light-curing resins (such as adhesive bonding to tooth structure and rapid material hardening by visible light exposure). In addition, their physical properties are improved over those of self-hardening glass-ionomer cements. The glass-ionomer-resin cements can be used to restore primary teeth quickly and successfully. The technique for simultaneously restoring adjacent Class II lesions in primary teeth is presented.

Restoration of Class II carious lesions in primary molars using light-hardening glass-ionomer-resin cement.

Light-hardening glass-ionomer-resin restorative cement was introduced in 1992. Besides having the advantage of rapid initial hardening by application of visible light, the new formulations have better physical properties than do self-hardening glass-ionomer restorative materials. This article documents use of one such cement for restoration of Class II carious lesions in primary molars. The rationale for use of the new cement is reviewed.

Visible light-hardened glass-ionomer-resin cement restorations for primary teeth: new developments.

Bonded glass-ionomer-silver-cement cement and visible light-hardened glass-ionomer liner and base material have proven to be reliable dentinal and enamel restoratives since the mid-1980s. When used within their limitations, they offer advantages over mechanically interlocked silver amalgam material. A light-hardened glass-ionomer-resin cement restorative material, which appears to have greater wear resistance and fracture toughness than prior glass-ionomer cements, has been introduced. This paper describes use of the new material and discusses its potential future implications.

Dentigerous cyst associated with trauma to a primary incisor: a case report.

Trauma to primary incisors is common and poses a challenge to dentists who treat children. Often, the clinical appearance of such teeth does not indicate the underlying pathosis. In this case, a dentigerous cyst developed in association with an injured primary incisor, resulting in loss of a permanent tooth.

Glass-ionomer-silver-cermet interim Class I restorations for permanent teeth.

Glass-ionomer-silver-cermet cement has proved to be a worthy alternative to silver amalgam for restoring certain Class I lesions in primary teeth. Such restorations are now known to last up to 8 years without need for repair or replacement. Cermet cement has also been used for interim restoration of permanent teeth in special cases, with ideal results. The procedure for placing a glass-ionomer-silver-cermet cement Class I restoration is described.

Zinc oxide-eugenol pulpotomy and stainless steel crown restoration of a primary molar.

The most durable and reliable method of retaining a primary molar in the mouth after a pulpotomy procedure is complete-coverage restoration with a preformed stainless steel crown. This paper describes a method for performing pulpotomy and stainless steel crown restoration of a primary molar. Neither formocresol, glutaraldehyde, nor calcium hydroxide is used during the pulpotomy phase of the treatment.

Cementation of a fixed orthodontic appliance.

Cementation of a fixed orthodontic appliance requires careful attention to detail. Certain procedures can be used to improve fit of the stainless steel band and enhance the cementing procedure. This paper outlines a technique for cementation that optimizes the chances for an ideal long-term band-cement-tooth bond.

Effect of enamel microabrasion compound on human gingiva: report of a case.

A new material to be used in the procedure of enamel microabrasion has been recently introduced. Because the compound contains hydrochloric acid, the manufacturer recommends many safety precautions, especially use of the rubber dam. This case report documents the effect of the enamel microabrasion compound on the gingiva of one human subject and verifies the need for careful handling of the material.

Dental twinning anomalies: the nomenclature enigma.

Dental twinning results from abnormal events in the embryologic development of teeth. This paper describes the impossibility of assigning precise diagnostic terms, such as germination, fusion, macrodontia, and concrescence, to dental twinning anomalies because the entire course of odontogenesis cannot be witnessed. Traditional nomenclature is reviewed and seven cases that exemplify the principle are presented. Modification of nomenclature to describe dental twinning defects is suggested.

Triplication and twinning in one dental arch: report of a case.

This report documents the case of a young patient who presented with dental conjoining anomalies in both sides of the maxillary arch. One defect involved primary incisor twinning and the other a rare instance of primary incisor triplication--three conjoined teeth.

Reproduction and teratogenic studies of 5-thio-D-glucose in mice.

Under the conditions of the present study, 5-thio-D-glucose was found to be an effective and useful reversible male contraceptive. Treatment of male mice with 5-thio, administered intraperitoneally or orally at 40 or 60 mg/kg for 28 to 35 days produced germinal cell degeneration and complete inhibition of spermatogenesis in the seminiferous tubules. These treatment regimens also resulted in complete sterility in males lasting for several weeks. Resumption of sperm development and fertility occurred with 5 to 6 weeks after treatment was discontinued. The Leydig cell population, Sertoli cells, and spermatogonia apparently were not affected and male libido was not impaired. There was no evidence of embryotoxic or teratogenic effect in litters of pregnant females treated orally with 5-thio on days 6--12 of gestation.

Enamel microabrasion to improve enamel surface texture.

Enamel microabrasion is effective in removing superficial enamel coloration defects. The technique has now also been shown to improve the appearance of enamel with surface texture irregularities. The method of microabrading teeth with surface texture defects is described, and several cases are documented.
