Kolker et al 8 concluded from an evaluation of year-old extensive amalgam restorations that such teeth should undergo a full-coverage procedure after 5 years to prevent restoration failure. Plasmans et al 10 evaluated the month success rate of amalgam restorations and concluded that success of extensive amalgam restorations alone or as a foundation for cast procedures shows no statistically significant differences. In addition, failure rate of amalgam restorations in older patients is higher than that in youngers.
A recent similar study in Iran on two-surface amalgam restorations showed that the most common reasons for restoration failures were, in descending order, proximal overhangs, recurrent caries and food impaction.
The higher frequency of cusp fractures in our study compared to the latter study might be due to our inclusion of endodontically-treated teeth and three-surface restorations. The mean age of the restorations was 15 years. The rate of amalgam margin fractures has decreased with the introduction of high-copper amalgams, 3 which is confirmed by the results of the present and previous studies.
However, this should not overshadow the importance of proper carving, burnishing and polishing of amalgam restorations. Another reason for replacing restorations in the present study was amalgam bulk fracture, which might be attributed to improper cavity design or recurrent caries resulting in undermining of the amalgam restoration. Amalgam cannot withstand tensional forces well; therefore, cavities should be prepared in a manner in which the material will have sufficient thickness and will not be subjected to tensional forces.
Such subjects did not have extensive restorations and seemed to have satisfactory oral health and hygiene status.
The findings of the present study emphasize the importance of proper education of dental practitioners and dental students in preventing restoration failures.
Subjects like cusp coverage and importance of follow-up visits should be emphasized in the curriculum for dental students and continuing education courses for dental practitioners. References 1. Chicago: Mosby; 5, , , Philadelphia: Quintessence; , Qualtrough et al 1 defined a cavity liner as an aqueous or volatile organic suspension or dispersion of zinc oxide or calcium hydroxide that can be applied to a cavity surface in a relatively thin film.
They included glass ionomer and RMGI cements as materials suitable for use as lining materials. Weiner 18 defined a cavity liner as a thin layer of material 0. Similarly, Heymann et al 3 defined liners as suspensions or dispersions of zinc oxide, calcium hydroxide, or RMGI that can be applied to a tooth surface in a relatively thin film.
Anusavice et al 19 stated that a cavity liner is a material that is used to coat the bottom of a prepared cavity to protect the pulp; it is applied in a thin layer and usually contains calcium hydroxide or mineral trioxide aggregate MTA ; it also includes certain glass ionomer cements used as intermediate layers between tooth structure and composite restorative material.
Both terms should not be used synonymously. Types In situations where a liner is indicated, there are several choices of materials. These liners are relatively weak in thin layers, soluble, do not stimulate reparative dentine, and demonstrate high interfacial leakage, for example, Cavitec Kerr Portland, OR, USA. MTA was also listed by some textbooks as a cavity liner.
The survey considered cavities with 1 mm remaining dentine thickness RDT as deep cavities since there were no strict guidelines for defining a deep cavity in the literature at that time.
Thirty-eight percent of the 39 dental schools involved in the survey reported that calcium hydroxide liners were taught for deep preparations with amalgam restoration followed by The survey also reported that for composite restorations in a deep cavities, the liners most frequently used were glass ionomers However, the survey did not offer scenarios that included composite restorations.
Calcium hydroxide aqueous suspensions are suspensions of calcium hydroxide in water. Calcium hydroxide liners, however, are a combination of calcium hydroxide with a varnish to modify the viscosity and to improve handling, 20 , 29 , 30 for example, Hydroxline George Taub, Jersey City, NJ, USA.
One paste contains calcium hydroxide and the other contains salicylate. Salicylate is a weak acid that is chemically similar to eugenol and reacts with the calcium hydroxide. Ideally, liners should possess antibacterial properties. The ability of these liners to prevent bacterial growth under restorations is of great importance as the numbers of bacteria in a cavity decrease the extent of pulpal inflammation is reduced.
Calcium hydroxide liners are reported to display antibacterial properties. The hydroxyl ions create an alkaline pH that is unfavorable for remaining bacteria in the cavity. Hydroxyl ions are highly oxidant free radicals that show high reactivity. Calcium hydroxide liners were also reported to reduce bacterial numbers much more effectively than only sealing the cavity.
Hence, it is recommended that they should be only applied over the smallest area that would suffice to aid in pulp therapy. Operative dentistry books recommend a calcium hydroxide liner if the excavation extends close to the pulpal tissue. In cases where the RDT is between 0. RMGI provides adequate sealing and protection to the dental pulp due, in part, to the chemical adhesion to dental substrates, fluoride release, decreased solubility, and superior mechanical properties.

Calcium hydroxide liners do not adhere to dentine or resin-based restorative materials. Hence, they provide a poor seal. The adaptation between dentine and Dycal and also between Dycal and Vitrebond 3M ESPE was evaluated under scanning electron microscope SEM , marked gaps were seen between Dycal and dentine, on one hand, and between Dycal and Vitrebond, on the other hand.
The study attributed the gaps to the lack of adhesion of Dycal to Vitrabond and dentine as well. Therefore, enough enamel and dentine should be left exposed for adhesion of the overlying protective RMGI layer since studies report good adaptation and bonding between dentine and Vitrebond.
There is little proof that VLC calcium hydroxide liners actually release calcium ions necessary for reactionary dentine formation. A study by Gandolfi et al 45 compared the release of calcium ions by Dycal, Life, and Lime-Lite and found that the amount of calcium released by Lime-Lite was negligible compared to that released by the chemical set formulas Dycal and Life.
There is little proof of considerable antibacterial effect of the VLC calcium hydroxide liners; the vehicle component of these light-cured products may prevent or significantly reduce any antimicrobial effects associated with the chemical cure products. They reported no antibacterial activity of the light-cured calcium hydroxide liner Prisma VLC Dycal and concluded that this material was inert.
Coogan and Creaven 37 reported that the antibacterial action of Prisma VLC Dycal is limited and its antibacterial properties were significantly less than that displayed by the chemically cured Dycal.
Similarly, Poggio et al 23 studied the antimicrobial effect of Calcimol LC and Dycal using an agar diffusion test and found Dycal to have a significantly higher antimicrobial activity compared to the Calcimol LC. They concluded that the VLC products are equally effective as standard self-curing, pulp capping products in inhibiting the growth of organisms commonly found at the base of a cavity preparation.
Yalcin et al 58 investigated the antibacterial effects of Dycal and the light-cured calcium hydroxide liner Calcimol LC using the direct contact test. The authors reported that both of these materials showed no antibacterial activity. Conclusion Calcium hydroxide liners should not be overused. Calcium hydroxide liners are used for its bioinductive and antimicrobial activity.

The placement of calcium hydroxide should be followed by a layer of RMGI to protect it from its drawbacks. Footnotes The author reports no conflicts of interest in this work.
