“…The clinical symptoms of dentine hypersensitivity (DH) is commonly reported during the clinical practice, in particular, subsequent to non-surgical periodontal therapy performed with sonic and manual instruments due to the removal of the thin layer of cementum in the cervical region and along the root surface (1)(2)(3)(4)(5). Dentine hypersensitivity is also induced by the enamel loss and/or the gingival root surface abrasion caused by the erosion, abfraction or gingival recession (6)(7).…”

Ultramorphology and dentine permeability changes induced by prophylactic procedures on exposed dentinal tubules in middle dentine

Objectives: The purpose of this study was to evaluate the changes in dentinal permeability (i.e. hydraulic conductance) after prophylactic treatments performed using prophy-powders with air-polishing system or prophy-pastes on exposed middle dentine. The changes in dentine morphology were evaluated by SEM. Study design: Commercial prophylactic pastes and air-polishing powders were tested in this study. Dentine discs from human third molars were used to study the quantitative reduction of the dentine permeability under simulated pulpal pressure (20 cm H 2 O). Further specimens were gold-coated and analysed using observed a SEM. Results: The results of this study showed different dentine permeability redaction based on the type of product employed (i.e. prophylactic paste or air-polishing powders). The use of Sylc bioactive glass and sodium bicarbonate were the most effective in reducing dentine permeability of the specimens. However, the air-polishing procedures performed with Sylc bioactive glass created a dentine surface devoid of exposed dentinal tubules due to the presence of a compact multilayered smear layer. Colgate Sensitive Pro-Relief and Nupro NU-Solution reduced the dentine permeability up to 69.8% and 66.9% respectively. Conclusion: Although all the tested products are able to statistically reduce dentine permeability, Sylc bioactive glass is an innovative and effective product which completely occludes the dentinal tubules during prophylactic procedures of air-polishing.

“…The healing of periodontal tissues after active periodontal therapy often results in gingival recession, and in addition, root debridement leads to loss of cementum [6, 7]. The short, sharp pain arising from exposed dentin in response to thermal, tactile, osmotic or chemical stimuli has been defined as dentin hypersensitivity [8].…”

Pain perception during debridement of hypersensitive teeth elicited by two ultrasonic scalers

et al. 2016

ObjectivesThe ultrasonic NO PAIN technology (Electro Medical Systems, Nyon, CH) promises minimal pain during debridement due to linear oscillating action combined with a sinusoidal power output and feedback control. The aim of the present study was to measure pain perception on a visual analogue scale (VAS) during supportive periodontal therapy including debridement of hypersensitive teeth. Two ultrasonic scalers were used, one with and one without NO PAIN technology.Material and methodsIn a randomized-controlled clinical study with split-mouth design, 100 hypersensitive teeth matched for air blast hypersensitivity were either treated with the ultrasonic device Piezon Master 700 or the Mini Piezon (both EMS, Nyon, CH). Pain perception during debridement was assessed by a VAS (range 0–10).ResultsThe average VAS for the test device Piezon Master 700 with NO PAIN technology was 3.16 ± 2.10, and for the control device Mini Piezon without NO PAIN technology 3.40 ± 2.59 (p = 0.490). Placing an arbitrary threshold at the VAS score of 3 for significant pain experience, 60 % of the subjects experienced no significant pain with either instrument.ConclusionNo statistically significant difference in perceived pain between the instruments used was found.Clinical relevanceBoth ultrasonic devices showed very small pain intensities during debridement of highly hypersensitive teeth and can therefore be recommended for supportive periodontal therapy.

Histologic Evaluation of Three Methods of Periodontal Root Surface Treatment in Humans

Abstract: The CO2 laser treatment, used at low power and in the defocused mode, combined with traditional mechanical instrumentation, could improve root surface debridement of periodontally involved teeth. More extensive, long-term studies are needed to confirm this hypothesis.
