The epidemiology of dental fluorosis derives from surveys carried out in recent years, as a result of a better comprehension of metabolic aspects of fluoride in the human organism and oral health concerns. This reflection aims at presenting studies carried out on fluorosis between 1993 and 2006. The period of 1993-2004 delimits the interval between the 2nd and the 3rd National Conferences on Or...
Chronic fluoride over-exposure during pre-eruptive enamel development can cause dental fluorosis. Severe dental fluorosis is characterized by porous, soft enamel that is vulnerable to erosion and decay. The prevalence of dental fluorosis among the population in the USA, India and China is increasing. Other than avoiding excessive intake, treatments to prevent dental fluorosis remain unknown. We...

OBJECTIVES To assess the prevalence and severity of dental fluorosis and dental caries among 12 and 15 years old children in relation to fluoride concentration in drinking water . SETTINGS AND DESIG...
Background: Periodontitis is multifactorial in nature. The effects of fluorosis as an environmental factor are not evaluated and researched to designate it as a risk factor similar to smoking. The primary objectives of this study were to investigate whether there is any association between fluorosis and periodontal disease and to assess salivary oxidative stress in fluorosed and nonfluorosed pa...
Background & Aims: The proper concentration of fluoride in drinking water can prevent dental caries and the concentration of above the standard causes dental fluorosis. The aim of this study was to determine the relationship between fluoride concentration in the drinking water with DMFT index and dental fluorosis in 11-12 years old students in rural areas of Oshnavieh. Materials & Methods...
Received: 28 Jun, 2015 Accepted: 4 Aug, 2015 Abstract Background & Aims: The present study aims to investigate the prevalence and severity of fluorosis and decayed, missing, and filled teeth (DMFT) in students aged 7-14 in villages of Maku. Materials & Methods: The present research was carried out on 240 school children that were divided into two groups according to clustering random s...
Introduction: Tooth decay is the most prevalent human disease after common cold. Although, fluoride in drinking water and daily meals can prevent teeth decay, its over consumption may cause fluorosis. This research was designed to study fluorosis prevalence rate in Bandar Abbas pupils, Iran. Methods: In this cross-sectional study, 867 pupils were randomly selected using a multi-stage sampling...
