Softness in nature is considered a godly virtue and being hard is misunderstood as pride, arrogance, insensitive etc, because of shortsightedness of people. Yet, experience will prove at the end that such folk who have not apparently shown pity were right mostly. Their goodness came in solid forms rather than like a pudding as it were. Determination to achieve is helped by some sense of obstinacy of though as long as that thought is productive. Sportsmen in particular are taught and trained to accept rigid disciplines if they have to excel. So it is in military. However, it is not to attempt anything beyond ability but abilities get developed through persistent striving to reach standards. Nature teaches us how to cope with negative looking surroundings and come out with productive outcomes. Scholars after achieving degrees are thankful for their tutors during primary education who were strict and exacting according to the childhood perception. They acknowledge the real worth of discipline.
In the field of dentistry and many synthetic productions a similar process is well applied through UV curing systems. Generally the abbreviation in front is exploited by skincare lotion manufacturers and sun cream sellers for the beach haunters. Little is known by the laymen and laywomen of the immense benefit of it dentistry where resins which have the materials responsive to this heat emitting radiation form sunlight. It does a marvel in that melting and hardening takes place in chosen areas of a substance – Similar to photosynthesis in plants where only that is exposed undergoes the change what to form chloroform. Further, this radiation with shorter wave lengths carries much energy that the ordinary visible light. Also it helps amalgamating any other substance with the primary compound.
A sensitive material gets to be hardened in this manner faster by UV curing systems. As such it is a time saving methodology as well. Although at first the areas which are sensitive to the process get processed, gradually other parts undergo the action as well. Therefore, it can be monitored and modulated as per the need. Ventilation or evaporation removals are not necessary as in other mechanisms. Many resins and glues have been found to be responsive to this radiation. Araldite an epoxy resin is one such. Even in vinyl flooring this source of energy is used much.
However, since this radiation is dangerous to the eyes it takes an extra-cautious dentist to apply it in the teeth. Everything under the sun has a dual quality. Good and the not-so-good. Take the beverage Tea for instance. It is a great health boosting tonic they say. But too much of it is something to worry about. So, sun has been the source of many a good thing for humanity. This is one that has been discovered no many years ago. There could be much more in it – the future will tell us. On the other hand all dentists are required to use proper gloves for the safety of their patient.
