The use of rotary instruments constantly grows as they offer many advantages, such as reduction in working time and better preservation of the original root canal morphology.The aim of this study was to discuss the advantages and drawbacks of rotary instrumentation techniques in older patients. Many older people suffer from significant illnesses restricting access to the dental office and demanding fewer and shorter working sessions. The use of rotary instrumentation may offer a reduction in the number of visits and the duration of the working sessions. They may also help access the root canal system and achieve patency easier and faster, taking into consideration the increased calcification rates and the secondary dentine deposition in older teeth. The drawbacks of the method include increased risk of instrument separation and the possibility of dentine microcracks as its elasticity reduces with ageing. Rotary systems may be useful tools for the contemporary dental clinician and can offer significant help in many demanding geriatric cases. Nevertheless, they must be cautiously applied after appropriate case selection and familiarisation with their use. More research is necessary on the comparison between the use of rotary instruments and hand files, particularly in older patients.

In many developed or even developing countries an increase in the retention rates of natural teeth in older persons has been recorded over the last decades (2-5).

A gradual change in the field of Endodontology, which has become a daily routine, is the use of rotary instruments. Rotary systems in Endodontology have offered many advantages, including reduction in working time (8, 9). Moreover, a better preservation of the original root canal morphology can be achieved, as well as a more effective standardisation of its final shape (10). Some years ago, skepticism existed concerning their use (11), but today they are regarded as a necessity rather than a luxury. To the best of our knowledge, the international 63
