Microabrasive tooth preparation for early caries prevention and treatment

Based on the 4-year experience with the method of air-abrasion treatment on the stages of treatment and prevention of dental caries in the article provides data on the indications for its use, benefits and complications.     

A technique for restoring an overflared root canal in an anterior tooth

This article describes a technique for fabricating a dowel and core for a tooth with an overflared root canal. The technique involves supporting a glass fiber-reinforced prefabricated dowel with chopped silanated glass fibers.     

Aesthetic replacement of an anterior tooth using the natural tooth as a pontic; an innovative technique

This article presents a novel technique for replacing an anterior tooth. A new modification to the clinical technique of direct fabrication of a resin-bonded bridge was employed, in which the patient’s natural tooth was used as a pontic. Treatment with this modification led to overall improved aesthetics and reduced treatment cost. The natural tooth pontic was stabilized in the extraction socket with a resin-wire splint as a provisional restoration to maintain the gingival architecture while the permanent bridge was being constructed.     

An esthetic, conservative reconstruction technique for an endodontically prepared tooth.

A reconstruction technique is presented for endodontically treated teeth in which a minimally invasive procedure is desired. A resin-bonded, laboratory-fabricated, heat- and pressure-cured composite resin onlay was used to achieve tooth support as well as esthetic results.     

Two-year study of alternative conservative treatment modalities for early anterior permanent tooth loss

Premature tooth loss in children may consist of single or multiple, primary or permanent, and anterior or posterior units of the dentition. This tooth loss may be due to either trauma or caries and, in some cases, to congenital or genetic defects. With anterior tooth loss cases, there are several problems the dental practitioner must consider. These are space maintenance, masticatory function, speech and esthetic appearance.     

Unusual ectopic eruption of a permanent central incisor following an intrusion injury to the primary tooth

Intrusive luxation of primary teeth carries a high risk of damage to underlying permanent tooth germs. Ectopic eruption of permanent incisors is an unusual outcome of traumatic injury to their predecessors. In this case report, we describe the multidisciplinary management of the consequences of a primary tooth intrusion that led to severe ectopic eruption of the permanent left central incisor in a horizontal position at the level of the labial sulcus.     

A new technique for determining the denture tooth bond

summary Defective bonds between resin teeth and denture base material remain a continuing source of failure. Findings from the limited number of studies on this topic are diminished by the numerous experimental approaches adopted. National and international standard specifications also adopt different methods of specimen preparation and physical straining. A critical appraisal of the various standards is carried out and a new procedure for determining the denture tooth to acrylic resin bond is described. A study using this technique found that physical modification and alginate contamination of the tooth had no significant effect on the bond strength. Ineffectual wax elimination was the main cause of failure.
