Bruxism the general population grind their teeth to a degree at some point during their life, although only 5% will develop a clinical condition. Some studies have reported that awake bruxism affects females more commonly than males, while in sleep bruxism, males and females are affected equally. Children are reported to brux as commonly as adults. It is possible for sleep bruxism to occur as early as the first year of life – after the first teeth (deciduous incisors) erupt into the mouth, and the overall prevalence in children is about 14–20%.

Diamond grinding of pavement pavement. Another important effect of diamond grinding is the considerable increase in surface macrotexture and consequent improvement in skid resistance, noise reduction and safety. The industry can be traced back to an event where a single diamond blade mounted on a concrete saw was used to groove concrete pavement in the late 1940s. Since that early tentative step, concrete grinding, grooving and texturing with diamond blades has developed into what is today a multimillion-dollar industry that is practiced worldwide. One of the first uses of diamond grinding of highway pavement was in 1965 on a 19-year-old section of Interstate 10
