Tooth wear: when to treat, why, and how. Part One.

A Comparative Study of Tooth Wear, Mechanical Power Losses and Efficiency in Normal and High Contact Ratio Asymmetric Spur Gears

The surface tooth wear which occurs at the gear contact region due to inadequate contact strength of the tooth is one of the predominant modes of gear failures. Currently, higher contact ratio spur gears are increasingly used in power transmission applications such as aircraft, wind turbine, automobiles and compact tracked vehicles due to their high load carrying capacity.  In this work, the di...

The Dahl principle in everyday dentistry

Private Dentistry October 2010 My first article on differential tooth wear, the Inman aligner, the Dahl principle and an alternative to preparomental dentistry (published in February’s Private Dentistry) resulted in me receiving quite a few emails. I was aware that the subject matter was a little controversial as the Dahl principle is often viewed as a slightly left field way of treating wear. ...

Assessment of Dental Students’ Knowledge of Tooth Wear, Its Diagnosis, Prevalence, Prevention, and Treatment

Background A sizable increase in the outbreak of tooth attrition and especially dental erosion has been observed. Detection of tooth wear, proper prevention, and effective intervention in the early stage will avoid the adverse effect on teeth performance and elegance. Thus, the current study aimed to determine the level of awareness of senior dental students (general dentists) about the preval...

Impacted and ankylosed teeth: why, when, and how to intervene.

With lateral crossbites occurring in 10% to 15% of children, one might ask: why treat these children early? One common answer is because of the risk for unilateral masticatory function and growth restriction, which might later lead to temporomandibular joint problems or facial asymmetry. Howeve...
