“…In pregnancy gingivitis, bacteria whose growth is enhanced by reduced oxygen tension such as the anaerobic species P intermedia and the capnophilic genus Capnocytophaga are found in high proportions. These species are also associated with the elevated plasma levels of estrogen and progesterone found during pregnancy (39). These hormones can favor the growth of these species by serving as nutrients, for example, as analogs of vitamin K. They additionally increase vascular permeability in the gingiva (116).…”

“…First, a thin removable layer formed by salivary biopolymers and various proteins appears, called “acquired” or initial pellicle, followed by primary bacterial colonizers, usually aerobic and facultative anaerobic gram-positive coccoids, such as different Streptococcus species (e.g., S. sanguinis , S. salivarius , S. mitis , S. oralis ) [9, 10]. This initial colonization together with subsequent deposition of protective extracellular matrices creates required preconditions for the successive incorporation of secondary microorganisms, especially anaerobic gram-negative coccoids and rods [9–11]. Depending on the bacterial composition and amount of growing biofilm, inflammatory reactions in the periodontal and peri-implant soft and hard tissues occur, which can lead in worst case to progressive bone resorption and early implant failure [7, 12–15].…”

The clinical success of osseointegrated dental implants depends on the strong attachment of the surrounding hard and soft tissues. Bacterial adhesion on implant surfaces can cause inflammatory reactions and may influence healing and long-term success of dental implants. Promising implant coatings should minimize bacterial adhesion, but allow epithelial and connective tissue attachment. Therefore, the present study has examined the bioactive effect of poly-(4-vinyl-N-hexylpyridiniumbromide) regarding typical oral bacteria as well as cytotoxicitiy to human cells considering different methods of connecting polymers to silicate-containing surfaces. The results revealed that the application of putative antibacterial and biocompatible polymer in coating strategies is affected by a variety of parameters. Published findings regarding reduced bacterial adhesion could not be verified using oral pathogens whereas hexylated polymers seem problematic for strong adhesion of soft tissue. Concerning innovative coatings for dental implants basic aspects (surface roughness, thickness, alkylation, combination with other polymers) have to be considered in further investigations.

“…1965, Suomiet al 1971, Lindhe et ai. 1975) and although considerable efforts have been made to develop a chemical plaque control agent, the results have so far been disappointing (Hull 1980, Laird & Grant 1983. Of the mechanical procedures, perhaps the most convenient is the use of an ultrasonic scaling instrument (Suppipat 1974), The removal of dental plaque and calculus from the tooth surface by the instrument is attributed mainly to the vibratory "chipping" action of the longitudinally oscillating scaling tip when the direction of motion is roughly parallel to the surface of the tooth (Johnson & Wilson 1957, Clark 1969.…”

Photomicrographs of the surfaces of recently extracted teeth stained with erythrosin dye were obtained. The stained surfaces were treated with an ultrasonic scaler using two different types of scaling tips driven by the same instrument operated at a medium power setting. Small areas of stained plaque removal occurred when the stationary scaling tip was operated without water cooling. Additional areas of removal were observed where a water coolant was present, which were larger than those produced by the non-water cooled tip. These additional areas were influenced by the type of scaling tip used, it's orientation to the tooth surface and it's displacement amplitude. Cavitational activity in the cooling water supply of the ultrasonic scaler is able to remove dental plaque from tooth surfaces and may be a useful adjunct to the mechanical action of the instrument.
