The research found that the babies’ teeth with certain genetic variants tend to appear later & that these chil- dren have a lower number of teeth by the age of one. In addi- tion,thosechildrenwhoseteeth develop later have a 35 percent increased likelihood of requir- ing orthodontic treatment. Some of the genes identified have been linked, in previous studies, with the development of the skull, jaws, ears, fingers, toes, and heart. The discovery may lead to innovations in the early treatment and prevention of congenital dental and occlu- sion problem.

In the control study conducted in 2009, samples of Streptococcus mutans and Escherichia coli were gassed immediately and after 1.5 hours with ozone for 24 seconds and several times. The results demonstrated that treatments with 24 seconds ozone had visible effects on the treated area. In all tests immedi- ate treatment was more effective than treatment after 1.5 hours. When the duration of the treat- ment was increased, the areas which contain no bacteria or have a low bacterial count also increase. W&H’s ozone generator has been available to dentists world- wide since 2008. Despite it’s sterilizable ergonomically hand- piece, it features preset prede- fined treatment times which make it easy to manage, the company states. Prozone is suit- able for a wide range of dental applications including cavity and surgical disinfection as well as periodontal and endodontic treatment. Treatment with ozone, a reactive three-oxygen molecule also found in earth’s atmosphere, is a relatively new concept in dentistry. Earlier studies indicate that it only takes a few seconds of therapy to kill 99 percent of bacteria making it a thousand times more power- ful than other bacteria killing agents.Thenewstudyshowsthat in order to reach the total poten- tial, treatment has to be per- formed immediately. Delayed treatment also results in reduced bacteria count but the visible effects are less significant. Devices utilizing ozone tech- nology such as Prozone expose filtered air to a highly electrical voltage which is directly applied to the treatment area where it destroys bacteria and viruses through oxidation.
