Community water fluoridation began in the 1945 as a public health measure to prevent and control caries and was implemented in Israel in 1981. Community water fluoridation reduced caries significantly, but in 2014, the Ministry of Health decided to stop Community water fluoridation in Israel. The aim of our study was to examine the effect of fluoridation cessation on the dental health of children aged 3-5, treated in "Assuta Tel Aviv" dental clinics, under general anesthesia or deep sedation. The computerized Maccabi-Dent database provided data for this retrospective study. Records from the years 2014-2019 including treatment codes for procedures relevant to the study, the number of stainless-steel crowns and restorations of all types were examined. Kruskal-Wallis test was performed to compare the results from before and after fluoridation cessation. A statistically significant increase in the mean number of treatments in the years after fluoridation cessation (P < 0.05) was found. There was approximately a two-fold increase in the number of all treatments for all ages. The results of the study emphasize the advantages of water fluoridation and are further proof of the need to restore community water fluoridation in Israel.
