In addition, it should be remembered that regardless of the degree of fluoride mottling, affected teeth are largely resistant to dental caries.
This report describes an unexpected, yet clinically significant, unusually high incidence of varying degrees of the clinical finding of dental fluorosis, also referred to enamel mottling, in an isolated island population.
This is a model somewhat similar to the research done in the Erode district, India, which also examined the prevalence of dental mottling in a relatively isolated community.
Symptoms caused by BPMV included mottling or mosaic on leaves, and slight to moderate leaf distortion.
Occurrence of seed coat mottling in soybean plants inoculated with Bean pod mottle virus and Soybean mosaic virus.
Effect of different strains of soybean mosaic virus on growth, maturity, yield, seed mottling, and seed transmission in several soybean cultivars.
Palouse has larger seeds when compared with Brewer and has an absence of seed coat mottling (Muehlbauer, 1992).
The large seed size and the presence of seed coat mottling are traits that should permit the replacement of Brewer by Merrit as a predominant lentil type in the U.S.
Variables measured were yield (kg [ha.sup.-1]), yield loss [(mean yield of 100% L78-379 in a replication-infected treatment yield)/ yield of 100% L78-379 in a replication, on a plot basis prior to ANOVA], seed weight (g x 100 [seeds.sup.-1]), seed coat mottling (% of seed with mottled seed coats), and seed transmission (%).

Measurement units were kg [ha.sup.-1] for yield, % for seed transmission and seed mottling, and g 100 [seeds.sup.-1] for seed size.
Soybean mosaic virus infection also increased seed coat mottling. The percentage of seed coat mottling was linearly related to the incidence level of SMV infection in both planting dates provided that infection occurred at or before flowering; however, if the soybean plants were infected by SMV after flowering the level of incidence did not increase seed coat mottling (Table 4).
