“…The authors view this dropout rate as normal, compared to dental clinical studies of the same duration. 34 In other studies, subjects dropping out of clinical trials typically have worse dental outcomes than those who remain. In the current study, subjects were more likely to return if they had problems, since the authors of the current study promised to replace the restorations at no charge.…”

The polymerization shrinkage of resin composites may affect restoration quality. A double blind, randomized clinical trial was carried out to compare two curing techniques-Soft-Start (SS) and the plasma arc curing light (PAC). The hypothesis that, delaying the gel point (with SS) improves marginal seal, was tested at alpha=0.05. Also, this report includes two-week, three-month, one-year and two-year results for post-op sensitivity. Twenty informed participants, each needing two Class II and/or complex Class I restorations, gave written consent. All the teeth were trans-illuminated to rule out pre-op crack lines before restoration placement. Clinical RelevanceClass I and II composite restorations placed with a Soft-Start technique showed no significant changes in post-op sensitivity to cold or any decreased signs of marginal stress. 266Operative Dentistry Sensitivity to a standardized cold stimulus was performed preoperatively at 2 weeks and at 3, 12 and 24 months. Patients rated their sensitivity after stimulus by means of a Visual Analog Scale (VAS). In addition, two independent, calibrated investigators evaluated the restorations clinically at each appointment. There were no significant differences in VAS scores between the two groups at any appointment period (two-way ANOVA; p>0.05).Several conditions were defined as indicating marginal stress before the start of the trial. At 24 months, there was no significant difference between the SS and PAC groups.Conclusion: Within the limitations of this study, Class I and II restorations placed with a SS technique did not show significant changes in post-op sensitivity or decreased signs of marginal stress.

“…Strand et al18 reported a higher failure rate of glass ionomer tunnel restorations in patients with high caries activity. This is also suggested by Ratledge et al4 who found that people with high caries activity had high risk of secondary caries 4. This may be due to the design of tunnel preparation, which does not clear the proximal contact, and the restorative margin in the proximal contact is subjected to cariogenic challenge by the plaque sheltered below the contact point.…”

“…The tunnel preparation was first reported in the 1960s for restoring distal proximal caries of a primary second molar, accessing caries beneath the marginal ridge and thus leaving it intact 4. In the 1980s, tunnel preparation was reintroduced with the use of glass ionomer cement 5,6.…”

The tunnel restoration has been suggested as a conservative alternative to the conventional box preparation for treating proximal caries. The main advantage of tunnel restoration over the conventional box or slot preparation includes being more conservative and increasing tooth integrity and strength by preserving the marginal ridge. However, tunnel restoration is technique-sensitive and can be particularly challenging for inexperienced restorative dentists. Recent advances in technology, such as the contemporary design of dental handpieces with advanced light-emitting diode (LED) and handheld comfort, offer operative dentists better vision, illumination, and maneuverability. The use of magnifying loupes also enhances the visibility of the preparation. The advent of digital radiographic imaging has improved dental imaging and reduced radiation. The new generation of restorative materials has improved mechanical properties. Tunnel restoration can be an option to restore proximal caries if the dentist performs proper case selection and pays attention to the details of the restorative procedures. This paper describes the clinical technique of tunnel restoration and reviews the studies of tunnel restorations.

“…The slot prep was compared and found to be a more reliable alternative. 20 When an amalgam is placed the matrix band is removed before the material setting and the restoration springs back and establishes a good contact. Unfortunately resin composite is set before the band removal and often leaves a gap between the new restoration and the adjacent tooth.…”
