Within the limitations of this small population study, age relative to the date when the new water well became operational was a significant risk factor in development of fluorosis. The first year of life was a significant period for developing fluorosis on the mandibular and maxillary central incisors.

A method was devised to record graphically the stress that patients experience during routine dental procedures. Heart rate was used as the indicator and the variations in it showed which parts of the treatment provoked the maximum stress reactions. This pilot study indicated that by using this method it is possible to study specific dental problems and methods for treating them.
