“…Despite the increased pulpal responses from amalgam initially as compared with ZOE, definite resolution was found as early as after 15 days. It has been shown that the factor of load or application of force in grinding procedures themselves can contribute to an intensification of the pulpal response, even though frictional heat was neutralized with adequate coolants (Stanley and Swerdlow, 1960). Soremark et ah (1968) showed that radioactive Hg 197 had reached the pulp in humans by six days, which was the shortest observation period used, if no cavity liner was used.…”

For many years, the dental profession worked mainly with rather inert restorative materials that had a limited contact with vital tissue, and the opportunity for local and systemic complications was minimal. However, conditions have changed in recent years where the two leading non-mercury-containing materials, resin composites and glass-ionomer cements, are chemically active compounds and can have detrimental effects on pulp tissue. With the advent of light-curing techniques with incremental layering, resin component formulae that were formerly found to be quite irritating to the pulp have become less so with the elimination of the need for matrices and pressure for good adaptation to be gained. As experience revealed the deficiencies and dangers of ultraviolet-light-curing techniques, visible-light-curing systems were developed that provided greater depth of cure, a higher degree of polymerization with less shrinkage with incremental layers, and less porosity. When glass-ionomer cements (GICs) were first introduced, with just one acid (polyacrylic), pulpal responses were classified as bland. With the addition of many more acids to enhance certain characteristics and reduce the setting time, GICs have become more irritating, especially when used as luting agents in areas where the remaining dentin thickness is 0.5 mm or less. Gold foil and amalgam are inert and innocuous restorative materials but require pressure for condensation which creates an exaggerated inflammatory response. This presentation emphasizes the pulpal responses and side-effects of these non-mercury-containing restorative materials and how to keep them within an acceptable range of biocompatibility. Despite the lack of any substantial appearance of soft tissue and systemic responses to resin composites and GICs, the results of a survey of recent literature are included.

“…2 Drilling can cause deleterious thermal 3 and pressure effects on the pulp. 4 The use of the handpiece may result in the removal of softened but uninfected dentin resulting in the excessive loss of tooth tissue. 5 A new chemo-mechanical caries removal system, Carisolve (Medi Team, Gothenburg, Sweden) has recently been introduced.…”

“…A number of mechanisms responsible for pulpal necrosis have been proposed. These include damage of the pulpal tissue by thermal trauma during crown preparation (Stanley & Swerdlow, 1960) bacterial invasion through exposed dentinal tubules (Brännström & Lind, 1965; Bergenholtz, 1977, 1989; Goldman et al ., 1992), damage by chemicals of the luting media (Hume, 1990, Al‐Fawaz et al ., 1993) and stressed‐pulp syndrome where pulps of teeth to be crowned have been previously subjected to injuries. The pulp therefore has reduced ability to recover from a new assault caused by preparation and crown cementation (Zach, 1972).…”

The aim of the present research was to evaluate intra-pulpal pressure with respect to a combination of factors that are known to reduce pulpward pressure transmission in the laboratory while maintaining acceptable seating of the crowns. Thirty premolars were prepared for full crowns and individual crowns were cast. Ten teeth were etched prior to crown cementation with 100 N seating force. Crowns of groups 2 and 3 were cemented with 10 N force, after dentine sealing with bonding agent. Group two received, in addition, oscillating seating force during cementation. Pulp chamber pressure during cementation and marginal seating discrepancy after cementation were recorded. Group 1 showed significantly higher pressure mean 600 Pa and better crown seating (mean -22 microm) compared with group two (mean 144 Pa and 24 microm) and group 3 (mean 102 Pa and 44 microm) (P=0.001). Low seating forces combined with die spacer and sealing of dentinal tubules resulted in significant reduction of pressure transmitted into the pulp chamber during crown cementation. It is suggested that pre-impression sealing of dentine be considered for crown preparations on vital teeth.
