Abstract
One important contemplation in periodontal therapeutic modalities is the root surface which
has become exposed to the oral environment as a result of periodontitis. Changes in pathologically
exposed root surface are physical and chemical in nature and also become cytotoxic due to the
release of bacterial toxins that get attached to the root cementum. In regenerative attempts the root
interface functions as one of the wound margins and must provide an appropriate surface for cell
attachment and fiber development if regeneration is to occur. Knowing that successful periodontal
therapeutic outcomes include clot stability, cell migration towards the root surface, cell attachment,
cell proliferation and differentiation, debridement and preparation of a root surface play an important
rule for the above-mentioned events which constitutes the rationale behind root bio-modification.
The most conventional method includes scaling and root planing which are primarily aimed at the
gross removal of cement from the root surface. Beside this method, nowadays the laser assisted
root debridement become very popular since the laser beam is capable of achieving a delicate
removal of tissue. Whatever method for debridement of root surface in order to detoxify,
decontaminate and demineralize is used, significant change in topography and roughness happens
which has impact on many properties of the environment that they support. The aim of this
presentation will be to outline some challenging aspects of a root surface roughness, after Er:YAG
assisted debridement, since it contain irregularities of various orders ranging from shape deviations
to irregularities of the order of interatomic distances.
