Effect of provisional cements on the bond strength of various adhesive bonding systems on dentine.

Temporization of prepared teeth is needed for protection of the pulp and the restoration of the patients' aesthetic and functional needs. When zinc-oxyphosphate cement is used, eugenol-containing provisional cements are preferred because of their sedative effect to the pulp and because of their acceptable compressive strength. However, prior to definitive adhesive cementation with composite luting resins and dentine bonding agents the use of eugenol-containing provisional cements has to be considered critical because eugenol severely disturbs the polymerization of resinous materials. The purpose of this study was to compare shear bond strength values of various adhesive luting systems on dentine which had been in contact with various provisional cements prior to dentine bonding. The results show that the provisional cements which were used considerably decreased some of the bond strength values of the dentine bonding systems tested. Freegenol and Fermit, however, seem to have beneficial effects on the SBS values of Syntac and ART Bond. The only bonding system which produces acceptably high average SBS values with a eugenol-containing provisional cement was P-Bond.

Mental nerve paresthesia associated with an adhesive resin restoration: a case report.

A case is reported in which mental nerve paresthesia was associated with an adhesive resin restoration placed in direct contact with the pulp of a mandibular molar. The restoration was removed, and the paresthesia had completely resolved after nonsurgical endodontic therapy. Epicutaneous patch testing response indicated a possible causal relationship between the filling material and paresthesia.

Is there life after Buckley's formocresol? Part II - Development of a protocol for the management of extensive caries in the primary molar.

OBJECTIVE: To produce a working clinical protocol for pulp therapy techniques in the extensively carious primary molar. INTRODUCTION: The International Agency for Research on Cancer has recently classified formaldehyde as carcinogenic to human beings. As such, a medicament that can be used to replace formocresol in clinical practice should be identified. METHODS: Part I of this paper explored the currently available alternative interventions and materials to formocresol in the form of a narrative review following an extensive literature search. Part II now presents the formation of a specialist group to establish an evidence-based protocol, for the management of the extensively carious primary molar. CONCLUSION: A protocol and key points document have been developed to assist clinicians in their treatment planning. Areas for further postgraduate training are identified.

Effectiveness of three minimal intervention approaches for managing dental caries: survival of restorations after 2 years.

The present study was aimed at comparing the effectiveness of three minimally invasive restorative treatment approaches for dentinal lesions in occlusal surfaces. The approaches tested comprised a conventional and a modified-conventional treatment and a modified Atraumatic Restorative Treatment (ART). The conventional approach was performed in a university dental clinic whilst the modified-conventional, employing portable equipment, and the modified ART, using hand instruments and a caries removal solution (Caridex, were carried out in the field. Using the split-mouth design, 430 matched contralateral pairs of occlusal cavities were restored with amalgam or glass-ionomers in permanent molars of 152 school children by one dental therapist. The restorations were assessed using a modified USPHS-Ryge criteria. After 2 years, the cumulative survival percentages for occlusal amalgam and glass-ionomer restorations were 92 and 96%, respectively. The survival of all restorations in the conventional, modified-conventional and the modified ART group was 96, 96 and 91%, respectively. The survival of occlusal amalgam and glass-ionomer restorations per treatment group was as follows: 94 and 99%, respectively (conventional group); 95 and 97%, respectively (modified-conventional group), and 89 and 93%, respectively (modified ART group). The differences in survival percentage between restorations with amalgam and glass-ionomer, and between the three restorative treatment approaches were not statistically significant. In countries facing scarcity in resources for dental care, ART seems a promising restorative approach to occlusal caries in posterior teeth. However, a longer clinical observation period is required to substantiate this initial conclusion.

Success of an alternative for interim management of irreversible pulpitis.

BACKGROUND: Extraction and endodontic therapy are treatment options for irreversible pulpitis. Extraction often is chosen for financial reasons. The authors conducted a study to investigate an alternative interim therapy. METHODS: The authors recruited patients (N = 73) with irreversible pulpitis and whose teeth were restorable but who opted for extraction owing to financial reasons. After undergoing pulpotomy, the teeth were restored by random assignment with one of two intermediate restorative materials: Caulk IRM (Dentsply Caulk, Milford, Del.) (Group I, n = 38) or an IRM base with glass ionomer core (Fuji IX GP, GC America, Alsip, Ill.) (Group II, n = 35). The authors monitored the teeth over six and 12 months for pain, integrity of restoration and radiographic periapical status by densitometric analysis. RESULTS: By six months, 10 percent of subjects remaining in the study (Group I, n = 27; Group II, n = 25) reported pain; by 12 months, 22 percent (Group I, n = 22; Group II, n = 18) reported pain. A two-tailed Fisher exact test showed no significant difference (P > or = .05) between groups at either time interval. No apical radiographic change was noted in 49 percent of teeth at six months (Group I, n = 18; Group II, n = 19) and 42 percent at 12 months (Group I, n = 16; Group II, n = 15). Chi2 analysis demonstrated no significant differences (P > or = .05) between groups. Seven of 22 restorations in Group I and four of 18 in Group II required repair at 12 months with no statistical difference (chi2 analysis, P > or = .05). CONCLUSIONS: The interim treatment of eugenol pulpotomy using either restorative material reliably prevented pain for six months. For longer periods, both restorations may require repair. CLINICAL IMPLICATIONS: This option should preserve the integrity of the arch and extend the use of the tooth while the patient finds the means to finance complete endodontic treatment.

Some principles in the selection and use of some tooth-coloured materials and techniques--1998.

In an era when many clinicians are confused or almost overwhelmed by the rapidity of change in the field of conservative dentistry, the purpose of this presentation/paper is to identify briefly, with 'bottom line' statements, the research evidence in many topics within this field. The fields to be covered are glass ionomer restorations, 'compomer' restorations, composite resins, 'posterior composites', post-restoration sensitivity, direct pulp therapy, resin bonding to enamel and to dentine.

Indirect pulp treatment: in vivo outcomes of an adhesive resin system vs calcium hydroxide for protection of the dentin-pulp complex.

PURPOSE: The purpose of this prospective and randomized in vivo study was to compare the clinical and radiographic outcomes of an adhesive resin system vs a calcium hydroxide liner for protection of the dentin-pulp complex of primary molars treated with indirect pulp treatment. METHODS: Forty-eight primary molars with deep occlusal caries, but without preoperative signs and symptoms of irreversible pulpitis, received indirect pulp treatment and were restored with a composite resin (Z100). The teeth were randomly divided into 2 groups according to the material used for protection of the dentin-pulp complex: (1) adhesive resin system (Scotchbond MultiPurpose); and (2) calcium hydroxide liner (Dycal). These teeth were evaluated clinically and radiographicaly for 2 years. RESULTS: After 2 years, 83% (19/23) of the teeth treated with calcium hydroxide and 96% (24/25) of teeth treated with only the adhesive resin system presented a successful outcome, as determined by clinical and radiographic examination. Interradicular and/or periapical lesions were the most predominant signs of treatment failure, since 3 out of 23 teeth treated with calcium hydroxide and 1 out of 25 teeth treated with only adhesive resin presented this outcome. One tooth treated with the calcium hydroxide liner was diagnosed with internal root resorption at the 18-month examination. Of the 5 teeth diagnosed from radiographs as a failure of the indirect pulp treatment, none presented clinical signs/symptoms of pulpitis or necrosis such as the presence of fistula, enhanced tooth mobility, or pain. CONCLUSIONS: This study demonstrates that protection of the dentin-pulp complex of primary molars with an adhesive resin system results in similar clinical and radiographic 2-year outcomes as compared to calcium hydroxide when indirect pulp treatment is performed in Class I composite restorations.
