Metronidazole is indicated in the treatment of symptomatic trichomoniasis in females and males when the presence of the trichomonad has been confirmed by appropriate laboratory procedures and in the treatment of asymptomatic females when the organism is associated with endocervitis, cervicitis, or cervical erosion. Metronidazole is also indicated in the treatment of acute intestinal amebiasis (amebic dysentery and amebic liver abscess). It is indicated in the treatment of serious infections caused by susceptible anaerobic bacteria. Indicated surgical procedures should be performed in conjunction with metronidazole therapy. In a mixed aerobic and anaerobic infection, antibiotics appropriate for the treatment of the aerobic infection should be used in addition to metronidazole. 

The ability of glass-ionomers to form a natural adhesive bond to the surface of the tooth is one of these material s most important clinical advantages. They were originally prepared from poly(acrylic acid), a substance chosen because of its use in the zinc polycarboxylate cement, a material known to adhere to the tooth surface [123]. The advantages of adhesion by these materials were apparent right from the start, when they were used for the repair of cervical erosion lesions and as pit and fissure sealants [124,125]. 

Traditional use Used in Iran and other eastern countries as a laxative and antipyretic (Khalmatov 1964). An infusion of the roots is used to treat liver diseases and stomach and duodenal ulcers as well as diuretic. A galenic preparation of the aboveground parts is used to treat colitis, gastritis, stomach ulcers, dysentery, cervical erosion, to heal wounds, to treat inflammation of the ear, nose and throat, as a choleretic, to quench thirst, to reduce sweating and as an antipyretic, antiinflammatory, and cough remedy (Karimov and Shomakhmudov 1993).

Begun in the 1950s, research on dentin bonding continued at a slow pace through the 1960s and 1970s and culminated in the introduction of the first commercial dentin adhesive in 1975 [85]. However, this product had very poor clinical results when used to restore cervical erosion lesions without mechanical retention [98],... 

A polymeric filling material which at present is still little used but has major potential when the properties are made more acceptable, is the glass ionomer (10) cement, known by the acronym ASPA - aluminosilicate glass, very similar to the glass of the dental silicate cement and an aqueous polyacrylic acid solution as the setting medium (Fig, 9). Its use currently is practically limited to cervical erosion repair. The more extensive application of this material has been hampered by the lack of esthetic appearance due to opacity and rather slow set. 

However, this view has been challenged. For example, Lee and Eakle [77] suggested that they arise from a combination of factors, of which occlusal stress is one, but with abrasion and erosion also playing a part. Similarly, Spranger [78] has proposed a combination of factors in the development of cervical lesions, and that the phenomenon is related to the tooth anatomy, occlusion and parafunction, all of which contribute to elastic deformation forces at the neck of the tooth and which are augmented by wear phenomena [78],... 

In addition to the effects of biomechanical loading causing the formation of non-carious cervical lesions, there may also be a role for erosion in their formation. Dental erosion is the loss of material from the tooth surface by the effect of strong acid but without the involvement of bacteria [103,104]. In other words, the acid involved does not arise from the metabolic activity of key bacteria in the oral biofilm but from the stomach (hydrochloric acid) or from components of the diet. These may be beverages of various kinds (cola, fruit juices) [105], or fruit or vinegar-based preserves eaten at or between meal-times. 

It has been suggested that erosion of this type may contribute to the development of non-carious cervical lesions because erosive agents enter the surface of the enamel through internal channels. Having done so, they would weaken the enamel by chemical attack from within. The resulting affected enamel would then be more susceptible to wear (tooth brush erosion) and fracture when loaded than unaffected enamel. This erosion might influence the formation of cervical lesions without having a primary role in their occurrence.
