We have previously shown that Swiss 3T3 cells aggregated on hydrophilic cellulose substratum Cuprophan (CU) establish short linear gap junctions composed of Cx 43 in cell surface plaques.
Uroplakin 2 is a major component of the surface plaques of the urothelium [ 55], is found exclusively in differentiated mammalian urothelium [ 56], and is a product of terminally-differentiated apical cell layer [ 57, 58].
Multivariate logistic regression analysis was conducted, controlling for socioeconomic status, social support (i.e., frequency of contacting friends and relatives), general oral health assessment items, number of decayed, missing and filled surfaces, plaque index and having regular dental visits.
All of these factors interplay in what can be described as the "application" phase (the initial interaction of relatively high concentrations of fluoride with the tooth surface and plaque), and the "retention" phase (the fluoride remaining in the mouth after brushing that is retained in saliva, plaque and plaque fluid, the tooth surface, and oral soft tissue reservoirs) [ 23- 25].
Also ask them the consider the moonwalk 'artifacts' that have endured, including the photographs of Neil Armstrong's boot and the American flag planted on the moon's surface, the plaque that reads: "We Came in Peace for All Mankind," the moon rocks collected on the surface.
Adequate polishing of the stripped teeth is essential for a good long-term prognosis, since scratches and furrows remaining on the enamel surface facilitate plaque accumulation and possibly caries development [11-13] [11-13]
Wet gauze pads, periodontal probes, toothbrushes, and dental floss were used to remove surface dental plaque [ 13].
The probe was used to clean the tooth surface from plaque and debris prior to examination and to check the surface texture of a lesion without penetrating it.
In both of these methods the activity of the lesion is based on the colour and texture of the tooth surface considering plaque stagnation.
Two important factors are (1) the initial interaction of relatively high concentrations of fluoride with the tooth surface and plaque during application and (2) the retention of fluoride in oral fluids after application.
