Class I restorations and restorations placed using rubber dam presented better AFR .
An elevated number of failures were observed due to recurrent caries , highlighting the need for professionals to work with a health-promoting approach .
BACKGROUND Several restorative material s with specific indications are used for filling cavities in primary teeth .
AIM To systematic ally review the literature in order to investigate the longevity of primary teeth restorations  and the reasons for failure .
Clinical evaluation of Dyract in primary molars: 1-year results.
PURPOSE To evaluate the 1-year clinical performance of Dyract in primary molars . MATERIAL S AND METHODS 55 children ( aged 4 - 9 years ) received 1 - 3 restorations ( n = 91 ) utilizing Dyract , a new restorative material combining properties of both glass ionomers and composites . RESULTS The so-called compomer material showed good h and ling characteristics and a survival rate of 97 % after 1 year . Nevertheless , the material demonstrated an average wear of 190 microns during 1 year , with 67 % of the restorations having occlusal wear of less than 200 microns . The combination of a low failure rate and the ease of application makes the compomer material very suitable for application in the primary dentition
