This was imperative to avoid contamination of the resin based cement to be used for luting selleck chem definitive crowns. Metal framework (Meganium GT, Megadental GmbH, Budingen, Germany) and porcelain (Noritake, Noritake Dental Supply Co., Ltd., Aichi, Japan) try-in were performed. The porcelain surface of each crown was glazed. The internal surface of crown surfaces was sandblasted (Sandblast Pen, RotaksDent, Istanbul, Turkiye) with 30�C40 micron alumina particles (mega-Strahlkorund, Megadental GmbH, Budingen, Germany ) under an air pressure of 4.2�C7 kg/cm2 and then the restoration surfaces were cleaned in an ultrasonic unit (Eurosonic Energy, Euronda, Vicenza, Italy) for 2 minutes. On the maxillary anterior region bonding strength of the single unit restorations was increased using resin based composite cement (Panavia F, Kuraray, Osaka, Japan).

The other desirable properties of this material are its exceptional low solubility and high tensile compressive strengths. Lower posterior restorations were cemented with glass ionomer luting cement (Aqua Meron, Voco, Cuxhaven, Germany). For the third year after treatment, the patient was followed for routine hygiene and assessment of long-term outcome (Figures 5, ,66 and and77).

DISCUSSION Dietary factors are the most common etiologic factor implicated in the development of dental erosion.

8 Fruits, fruit juices and candies with high concentrations of citric acid, carbonated beverages in which citric and phosphoric acids, are the usual extrinsic dietary instigators of dental erosion.9�C11 In this report, the excessive wear because of lemon chewing restored with multidisciplinary approach was reported. The slowly chewing lemon has an excessive wear effect just as it is in this case.5�C7 Erosion, abrasion and attrition are becoming more significant as the life expectancy of mankind increases. Such lesions are becoming more frequent, causing several unpleasant symptoms and serious problems in the stomatognatic system. According to some authors as much as 25% of the pathological destruction of hard dental tissue can be attributed to non-carious processes.12 The lesions are not only an aesthetic problem but also a functional are with the possibility of loss of masticatory units.

Saliva, with its buffering capacity and its ability to form a protective enamel pellicle, can control dental decalcification.9,13 The reduction or loss of salivary buffering capacity would contribute to the process of enamel erosion, the occurrence and the progression of dental erosion in this respect has been pointed out by various GSK-3 authors.14,15 An acid challenge results in under saturation of salivary salts (calcium, phosphate) and tooth demineralization with softening of dental enamel occurs.
