Indirect pulp treatment of primary posterior teeth: a retrospective study.

PURPOSE: This study was performed to assess retrospectively the clinical and radiographic success of indirect pulp treatment (IPT) on primary posterior teeth, and to compare the influence of caries risk, skills of the operator, and restorative material on the success of IPT. METHODS: A retrospective review of records of patients treated with IPT in the pediatric dental clinic at The University of Michigan, School of Dentistry from July 1993 through July 1999 was completed in January 2000. Two hundred fifty-five records with IPT were reviewed, from which 132 patients met the inclusion criteria, with 187 primary posterior teeth treated with an IPT. The patients were followed clinically and radiographically for a time ranging between 2 weeks to 73 months. Data were analyzed using survival analysis methods. RESULTS: The success of IPT was 95% (178/187 teeth), with only 9 failures. The 1-year probability of survival of each tooth was estimated to be 96% using an exponential survival model. The use of a base over a calcium hydroxide liner significantly increased the success rate of IPT (P = .0095). The use of a stainless steel crown (SSC) after an IPT was significantly more successful than the use of an amalgam (P=.026). IPT performed on primary first molars failed more frequently than on second primary molars (P = .045). There was no significant difference between maxillary and mandibular primary molars. CONCLUSIONS: Indirect pulp treatment is a successful technique and should be considered as an alternative pulp therapy procedure in deeply carious primary posterior teeth. The use of a base over the liner in addition to a SSC dramatically increases the success of an IPT.

Assessment of chair side techniques for composite resin restoration--a survey.

The purpose of this survey was to assess the awareness of dental practitioners relating to chair side techniques in restoring teeth with light cure composite. The survey package consisted of a consent form, a leaflet stating the rationale and purpose of the survey and the questionnaire. Randomised sample of dental surgeons in practice was selected. The collected data was then analysed. A 52% response was obtained. Gross deficiencies in practice technique were observed, especially related to parameters like isolation, etching, bond and composite application and finishing of the restoration. Significantly individual assessment of problems by dental practitioners was found to be different from objective rationale. It is suggested that adequate and periodic re-evaluation of techniques must be made by the general dental practitioners, through continuing dental education or workshops so as to achiEve optimum quality.

Self-etching adhesives and postoperative sensitivity.

PURPOSE: To test the hypothesis that the prevention of postoperative sensitivity in resin-based composite restorations is better achieved with a self-etching/self-priming (SE/SP) dentin bonding system without lining than with an early generation total-etch (TE) bonding system. METHODS: Over a 4-year period, clinical follow-ups were conducted on patients who had received composite restorations. The depth of each cavity was categorized as being shallow, medium or deep, and an evaluation was made regarding the need for pulpal protection for each restoration. Three different self-etching/self-priming (SE/SP) adhesive systems were compared to three different total-etch (TE) adhesive systems. The incidences of postoperative sensitivity (IPS) were examined by a standardized procedure 1 week after placement of the restoration. Patients' ages varied between 16-83 years. RESULTS: The total number of restorations placed in vital teeth were 330 for 150 patients in the SE/SP group, and 126 for 70 patients in the TE group. Incidences of IPS in the total number of restorations stratified for depth were 14% in deep cavities, 6% in medium depth cavities and 5% in shallow cavities in the SE/SP group, and 35% in deep cavities, 16% in medium and 4% in shallow cavities in the TE group. Fisher's exact test showed the incidence of IPS was significantly higher in cases of deep (P< 0.05) and medium (P< 0.05) cavities. The test also revealed that in restorations placed with the SE/SP adhesive systems, the presence or absence of a protective liner or base made no significant difference in the IPS in medium and shallow cavities, while the use of such protective layers produced a significantly higher IPS (21%), compared with no protection (0%), in deep cavities (P< 0.05). The absence of protective liners or bases did not result in postoperative sensitivity in deep cavities, when the SE/SP dentin bonding systems were used.

On the diagnosis and management of neurocutaneous syndrome, a toxicity disorder from dental sealants.

Neurocutaneous syndrome, a newly discovered toxicity disorder, is characterized by neurological sensations, pain, depleted energy, and memory loss as well as itchy cutaneous lesions that may invite various opportunistic infections. Components in the calcium hydroxide dental sealants Dycal, Life and Sealapex have been identified as sources of the observed symptoms. Sulfonamide and neurological toxicity issues are discussed, and three case histories are presented. Additional notes on zinc oxide, Fynal, IRM, and Sultan U/P sealers are also included. Diagnostic and management protocols at the Parasitology Center, Inc., are proposed.

Radiographic assessment of primary molar pulpotomies restored with resin-based materials.

PURPOSE: The aims of this study were to: (1) retrospectively assess the overall performance of formocresol pulpotomies in primary molars when definitively restored with a resin-based material; and (2) compare the results to previously published studies using more traditional restorative techniques (stainless steel crown, amalgam). METHODS: Records of a 2-operator pediatric dental office using this novel restorative technique were reviewed. Pre- and postoperative radiographs of pulpotomized primary molars restored with Z-100 and with a minimum of 6 months of follow-up were compared to the contralateral nonpulpotomized tooth. Radiographic success was determined by the absence of furcation/periapical osseous radiolucency and internal/external pathologic root resorption. Patient's age, gender, tooth type and arch, follow-up time, ZOE base type used (IRM only or IRM with glass ionomer overlay), and number of surfaces involved were the variables analyzed in the study. Statistical analysis was performed using chi-square analysis. RESULTS: Fifty-nine teeth in 52 patients met the selection criteria. Patient's age at treatment ranged between 44 and 118 months, with an average follow-up time of 21 months (range = 7 to 43). Significant failure rate was found in the mandibular arch (P = .035). When only the occlusal surface was restored, 100% success was obtained. With proximal restorations, 83% (15/18) success was obtained when the base was IRM followed by glass ionomer and 69% (22/32) success for IRM only (P = .259). CONCLUSIONS: Overall, restoration of pulpotomized primary molars with resin-based material was inferior to reported success rates using stainless steel crowns. When proximal surfaces were restored, the failure rate (26%) was comparable to amalgam (23%). Prospective studies with larger sample size are necessary for definitive conclusions.

Clinical and radiographic evaluation of pulpotomies employing calcium hydroxide and trioxide mineral aggregate.

This study utilized clinical and radiographic examinations to compare the effectiveness of calcium hydroxide paste and mineral trioxide aggregate (MTA) for pulpotomies of primary molars in children. Ninety primary molars that showed clinical and radiographic indications for pulpotomy treatment were selected. The pulpotomies were performed in two sessions, using a corticosteroid/antibiotic solution as therapeutic dressing. The sample was divided into two groups of 45 teeth, in which the pulpal remains were protected with either calcium hydroxide paste (Group 1) or MTA (Group 2). Radiographs were taken immediately and at 3-, 6-, and 12-month follow-up appointments. Three teeth in Group 1 failed after three months, while two cases failed after six months and one more failed at one year. Two failures were found in Group 2 at the 12-month follow-up. These results indicate that both materials may be utilized for pulpotomies in primary teeth.

Restorative and endodontic management of an anomalous mandibular molar.

Morphologic variations of dental hard tissue should be recognized and considered during restorative procedures. Overlooking anomalies increases the potential for clinical complications. Amalgam was used erroneously in a patient when the presence of a paramolar structure was overlooked. The clinical complications that resulted from overlooking the anomaly led to restorative, endodontic, and periodontal failures. The present report describes the use of conservative endodontics and a cast restoration, taking into account the presence of the paramolar structure, to correct the case.
