“…For clinicians, this work demonstrates that the type of generator mechanism (magnetostrictive or piezoelectric) does not affect the pattern of oscillation of the ultrasonic probe. What will have more of a potential influence on the clinical result is the shape and design of the probe, which has been shown previously to affect root surfaces (Jepsen et al 2004). Future studies should consider this aspect of the ultrasonic scaler as a factor affecting tooth surface defects.…”

“…These damages increase exponentially as the ultrasonic power is increased from medium to high. It is also revealed that instrument contact time, angulations and design of the tip, tip to tooth angle, power level of the unit, sharpness of the working edge, instrument pressure are important on the degree of root damage (43–45).…”

Periodontal therapy aims at arresting periodontal infection and maintaining a healthy periodontium. The periodic mechanical removal of subgingival microbial biofilms is essential for controlling inflammatory periodontal disease. Mechanical periodontal therapy consists of scaling, root planing and gingival curettage. The sonic and ultrasonic scalers are valuable tools in the prevention of periodontal disease. The vibration of scaler tips is the main effect to remove the deposits from the dental surface, such as bacterial plaque, calculus and endotoxin. However, constant flushing activity of the lavage used to cool the tips and cavitational activity result in disruption of the weak and unattached subgingival plaque. The aim of the study was to review the safety, efficacy, role and deleterious side-effects of sonic and ultrasonic scalers in mechanical periodontal therapy.

“…However, root and dentin surfaces are also vulnerable to physical injury. Because of the low mineral content, root surfaces are easily abraded by toothbrushing, and although cementum formation triples throughout life, reaching a thickness of about 50 μm in the coronal part of the root at the age of 20 [Furseth and Mjör, 1979], exposed cervical root cementum is often damaged and/or removed by regular scaling and root planing [Jepsen et al, 2004]. Therefore, in clinical circumstances the exposed root often presents a dentin surface.…”

Ecological Hypothesis of Dentin and Root Caries

Recent advances regarding the caries process indicate that ecological phenomena induced by bacterial acid production tilt the de- and remineralization balance of the dental hard tissues towards demineralization through bacterial acid-induced adaptation and selection within the microbiota - from the dynamic stability stage to the aciduric stage via the acidogenic stage [Takahashi and Nyvad, 2008]. Dentin and root caries can also be partly explained by this hypothesis; however, the fact that these tissues contain a considerable amount of organic material suggests that protein degradation is involved in caries formation. In this review, we compiled relevant histological, biochemical, and microbiological information about dentin/root caries and refined the hypothesis by adding degradation of the organic matrix (the proteolytic stage) to the abovementioned stages. Bacterial acidification not only induces demineralization and exposure of the organic matrix in dentin/root surfaces but also activation of dentin-embedded and salivary matrix metalloproteinases and cathepsins. These phenomena initiate degradation of the demineralized organic matrix in dentin/root surfaces. While a bacterial involvement has never been confirmed in the initial degradation of organic material, the detection of proteolytic/amino acid-degrading bacteria and bacterial metabolites in dentin and root caries suggests a bacterial digestion and metabolism of partly degraded matrix. Moreover, bacterial metabolites might induce pulpitis as an inflammatory/immunomodulatory factor. Root and dentin surfaces are always at risk of becoming demineralized in the oral cavity, and exposed organic materials can be degraded by host-derived proteases contained in saliva and dentin itself. New approaches to the prevention and treatment of root/dentin caries are required.

Significant influence of scaler tip design on root substance loss resulting from ultrasonic scaling: a laserprofilometric in vitro study

Abstract: The present investigation could demonstrate that the aggressiveness of magnetostrictive and piezoelectric ultrasonic devices to root substance was significantly influenced by the scaler tip designs, increasing for wider scaler tips as compared with narrow, probe-shaped inserts.
