The purpose of this retrospective study is to determine whether the type of home brushing instrument used by periodontal patients can affect recare compliance and tooth retention. Data from 201 cohorts, half of which used a rotary mechanical brush, were evaluated throughout 10 years. At recall, 25% of the manual and 67% of the rotary users exhibited good to very good oral hygiene, the rotary group lost 0.082 teeth/patient/year compared with 0.185 teeth/patient/year, and 92% of the rotary group maintained acceptable recare intervals compared with 51% of the manual group. The findings for the efficacy of the rotary brush for these 3 parameters are both statistically and clinically relevant.

The predictability of implant fixtures as a long-term solution for edentulous areas has improved to the point where they have become the standard of care in many situations, in lieu of fixed prostheses. At the same time, the success rate of endodontically treated teeth, and those requiring retreatment, is very high as well. The dilemma presented to the clinician in treatment planning is when to retreat a tooth or extract and place an endosseous root-form implant. Risk assessment for prognostic evaluation plays an important role in the decision-making process. The clinical and systemic factors affecting the longevity of a tooth need be considered as well as location, bone quality and amount, and the condition of the patient's other teeth. This article attempts to provide a meaningful algorithm that will provide a basis for an appropriate choice of therapy.
