Brief Summary

Fluorosis is caused by hypomineralization in the enamel due to increased fluoride ingestion during early childhood (Cawson.1, Wong et al. 2, and Sudhir 3). A considerable amount of evidence has been reported over the years, which has shown that presence of fluoride ions at up to one part per million in public water supply has reduced the prevalence of teeth decayed with minimal chance of dental fluorosis. The WHO recognized these facts by its resolution in 1969 4 and 1975 5, which stated that water fluoridation, where applicable, should be the cornerstone of any national policy of caries prevention

Conditions

Keywords

fluoride; mottling; libya; fluorosis

Outcome Measures

Primary Outcomes (1)

• Grading of mottling

  If there was fluorosis, the tooth or teeth were diagnosed as having fluorosis and coded according to the method produced by Al- Alousi 10, as follows A. White areas less than 2mm in diameter. B. White areas of or greater than 2mm in diameter. C. Colored (brown) areas less than 2mm in diameter, irrespective of there being any white areas. D. Colored (brown) areas of or greater than 2mm in dimeter, irrespective of there being any white area. E. Horizontal white lines irrespective of there being any white, non-linear areas. F. Colored (brown) or hypo-plastic areas.

  From baseline to 5 months

Study Arms (1)

observational

Total of 2015 Libyan school children aged 7 to 16 years, from urban (Tobruk) and rural (Kufra) areas were included in the main study. The children were of almost equal number of both sexes from each age group (table-I) .The total of 1935 children were examined for enamel fluorosis

Eligibility Criteria

• Age: 7 Years - 16 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)
• Sampling Method: Non-Probability Sample

Study Population

This study is part of a cross - sectional investigation of aspects of dental health in rural and urban Libyan school children. Total of 2015 Libyan school children aged 7 to 16 years, from urban (Tobruk) and rural (Kufra) areas were included in the main study. The children were of almost equal number of both sexes from each age group (table-I) .The total of 1935 children were examined for enamel fluorosis, the remaining, eighty children were excluded because they failed to meet inclusive criteria.

You may qualify if:

• Libyan children born and lived in the same area. 2. Limited to incisors only.

You may not qualify if:

• Non- Libyan children. 2. Children who born or lived outside the study areas. 3. Incisors with class II fracture (Ellis type 1970) or crowned
