“…A total of 5 measurements were calculated in each sample surface at different directions and locations with 0.25 mm cut off and 0.8 mm trace-lengths, having 0.1 mm stylus speed per second. Average root surface roughness (Ra) (mean between peaks and valleys of the surface profile) [ 9 ] was evaluated before and after instrumentations, and recorded as an average of these 5 measurements as described by Gursoy et al [ 10 ] Mean roughness height (Rz) (mean of five peaks and five valley height in each cutoff) [ 9 ] and maximum roughness depth (Rmax) (the maximum peak to valley of a profile) [ 13 ] were evaluated following instrumentations.…”

“…The use of different types of periodontal instruments in non-surgical periodontal treatment has different disadvantages such as the loss of the instrument sharpness within time, limited tactile sensitivity and requirement of an adequate experience in order to achieve ideal treatment outcomes [ 9 ]. In recent years, Er:YAG lasers are also stated to remove calculus and smear layer from the diseased root surfaces without harming the neighbouring soft tissues [ 6 , 10 , 11 ]. The aim of the present study was to compare root surface roughness and morphology following the use of Er:YAG laser 30°-angled tip, new generation ultrasonic tip and conventional curette in vitro.…”

Aim The aim of the present study was to evaluate the efficacy of 30°-angled Er:YAG laser tip and different periodontal instruments on root surface roughness and morphology in vitro. Methods Eighteen bovine teeth root without carious lesion were decoronated from the cementoenamel junction and seperated longitidunally. A total of 36 obtained blocks were mounted in resin blocks and polished with silicon carbide papers under water irrigation. These blocks were randomly assigned into 3 treatment groups. In Group 1, 30°-angled Er:YAG laser (2.94 μm) tip was applied onto the blocks with a 20 Hz, 120 mJ energy output under water irrigation for 20 s. In Groups 2 and 3, the same treatment was applied to the blocks with new generation ultrasonic tip and conventional curette apico-coronally for 20 s with a sweeping motion. Surface roughness and morphology were evaluated before and after instrumentation with a profilometer and SEM, respectively. Results After instrumentation, profilometric analysis revealed significantly higher roughness values compared to baseline in all treatment groups(p < 0.05). Laser group revealed the roughest surface morphology followed by conventional curette and new generation ultrasonic tip treatment groups (p < 0.05). In SEM analysis, irregular surfaces and crater defects were seen more frequently in the laser group. Conclusion Results of the study showed that the use of new generation ultrasonic tip was associated with smoother surface morphology compared to 30°-angled Er-YAG laser tip and conventional curette. Further in vitro and in vivo studies with an increased sample size are necessary to support the present study findings.

Objective:The aim of this study was the profilometric evaluation of the changes in root surface roughness created by different types of ultrasonic tips and mechanism of action.Methods: Thirty root dentine samples obtained from 15 maxillary premolars, extracted for orthodontic reasons, were included in the study. The sample surfaces were embedded into acrylic blocks, polished, and divided into 3 study groups as linear oscillating device (LOD) with straight tip (ST); LOD with perio-curette tip (PCT); conventional ultrasonic scaler tip (CUST). A calibrated clinician instrumented all surfaces in each group. The root surfaces were evaluated before and after instrumentations with a profilometer device.Results: There were no statistical differences between the initial roughness values of the groups (p<0.05). Multiple comparisons of aftertreatment values and differences before and after instrumentations revealed statistical significances (p=0.041; p=0.016, respectively). CUST group showed the highest surface roughness in comparison with the LOD groups. LOD with ST revealed the smoothest surface followed by LOD with PCT and CUST. Conclusion:Within the limits of this study, it may be concluded that fine and delicate tips with linear oscillating movement may be considered as the choice of insert for subgingival instrumentation due to the gentler mechanism of action than the conventional ultrasonic scalers.

Root-Planing Efficiency of Edge Retention Curettes After Extended Use on the Surface of the Tooth Root

et al. 2022

The present study aimed to evaluate the root surface topography and cutting-edge retention after mechanical root planing using five different types of curettes. Sixty premolars were divided among stainless steel curette (SS), titanium-coated curette (SC), titanium curette (Ti), EverEdge curette (EE), and XP curette (XP) groups. Mean tooth surface roughness (Ra) and the mean roughness depth (Rz) values were determined. The SEM and EDX values were checked after 40, 500, 1,000, and 2500 strokes. At 40 strokes, the mean Ra value of 2.33 ± 0.88 and mean Rz value of 18.5 ± 5.70 was the lowest recorded for titanium coated instrument. After 500 strokes, XP curettes presented with the lowest Ra and Rz values of 1.39 ± 0.25 and 12.32 ± 1.76, respectively. After 1000 and 2500 strokes, the XP curettes had Ra (1.02 ± 0.07; 0.71 ± 0.12) and Rz (9.63 ± 0.50; 7.20 ± 0.96), respectively. The 2-way ANOVA of Ra and Rz values and the post hoc showed a statistically significant difference with p < 0.05. The SEM analysis showed the surface of the roots to be smoother in XP, and the cutting was retained in XP and the EE curettes. In the EDX analysis, there was corrosion on the lateral surface of the Ti and the SC. XP curettes showed to be better statistically than other curettes, and both XP and EE retained the cutting edges longer. Hence, curettes with edge retention technology are long-lasting and effective for root surface instrumentation in periodontal practice.
