There is a considerable difference between males and females in the prevalence of these teeth in permanent dentition; hyperdontia is twice as common in males as in females. However, this approximation varies in terms of location, other associating syndromes that may be present, and the ethnicity of the individual. In terms of ethnicity, it can be seen that hyperdontia is in fact less common in European than in Asian populations. There is evidence to show that an individual is more likely to have hyperdontia if other members of their family also have the condition. References

Ramelteon, along with other melatonin receptor agonists like melatonin, has been repurposed in clinical trials as an adjunctive treatment for acute manic episodes in subjects with bipolar disorder. Nonetheless, meta-analytic evidence is based on very few trials and does not allow supporting the use of melatonin receptor agonists as adjunctive options for mania in clinical practice, although the small sample size do not allow ruling out their beneficial effect.
