“…The term "marginal leakage" appeared a few years later in 1961 [101]. The catchy term "microleakage", which has remained to this day and suppressed all preceding descriptors, appears in a few IADR meeting abstracts from 1959, but the first actual article containing the term was published in 1966 [102]. The derivative term "nanoleakage" appeared some 30 years later, to denote localized leakage within the tooth-adhesive interface [103], although the 50 wt.% silver nitrate that is used as a marker by then had already been used in microleakage experiments for a decade [104].…”

Objectives: To critically appraise experimental ex vivo research that has focussed on secondary caries, and to offer possible explanations for the seemingly poor correlation to clinical observations. Methods: The literature relating to the etiopathogenesis or prevention of secondary caries gained from experimental ex vivo research was reviewed, with particular emphasis on microleakage and artificial caries-like lesions.Results: It is doubtful whether a caries wall lesion can exist independently of an outer enamel caries lesion. Microleakage experiments apparently continue to emerge regardless of multiple reviews questioning the reliability and validity of the method. Several of the approaches used to generate artificial caries-like lesions are very aggressive. Remarkably little discussion has evolved about how these aggressive approaches create microenvironments that do not occur in reality. Corrosion-and biodegradation products may influence the biofilm qualitatively and quantitatively and it is difficult to replicate these variables in any ex vivo environment. Clinical data sampling method, patient demography as well as study methodology influences the incidence and prevalence estimates of secondary caries. Clinical results based on clinical work in settings where cost per unit time is of nominal concern do not provide any indications on how the restorative material will perform when placed by the average dentists in the mouths of their spectrum of patients during a busy workday.Recommendations: The term "wall lesion" including its variants is ill defined, has been, and is still being used indiscriminately. Stakeholders should avoid using this ambiguous label due to its connotation to an entity that does not exist per se.

“…The root apices were sealed with green stick impression material, and three coats of nail varnish were applied to the surface, except in the area of the restoration, and allowed to dry. The teeth were immersed in 1% methylene blue dye solution and stored in an oven at 35°C for 24h, using a similar procedure to that adopted by Going and Sawinski (1966).…”

A previous investigation identified three types of cuspal movement that occur as a result of polymerization shrinkage when extracted molar teeth are filled with a microfine or hybrid composite used in conjunction with a dentine adhesive. That investigation was extended further by dye penetration and SEM studies of the margin, involving assessment of the degree of dye penetration and marginal integrity around the restoration. These studies indicate that there may be a failure of the adhesive bond between tooth and composite/adhesive complex which correlates with little or no cuspal movement. Failure within the tooth structure itself was also observed in a number of cases.

“…In the study by Phillips et al [1973], the composite material was com pared with amalgam in 124 paired posterior restorations, and superior marginal adapta tion was found with the composite. Two mi croleakage studies [Going and Sawinski, 1966;Guzman et al, 1969] have compared leakage around amalgam and composite res torations using radioisotope methods. Re sults showed a better initial seal with the composite material than with amalgam.…”
