Abstract
INTRODUCTION Innovative technologies from other fields of science are constantly being introduced in medicine. Research works on animals strongly confirm the belief in better results following ultrasound and laser surgery. The main conclusions are based on observations from different animal species, whose biological characteristics differ from those of humans. This requires scientific experiments to be performed and confirmed in humans. MATERIAL & METHODS Human mandible specimens harvested in vivo by a conventional low-speed rotary device, an ultrasonic unit, or an Er: YAG laser were studied and analyzed to compare their effects on bone morphology and tissue response following surgery. RESULTS The cutting surface of eighty biopsies was studied, as well the facial edema, pain levels, and jaw dysfunction were followed up in the same eighty patients from whom the slices were obtained. In the piezosurgery and drill groups, the borders exhibited irregular edges full of bone fragments and debris. Thermal alterations within the superficial surface in all bone samples were generally minimal. In all specimens, intact osteocytes were detectable away from the area of direct action of the bone-cutting device. It was established, that the reactive facial edema, pain levels, and jaw disfunction were with milder values following in vivo osteotomy by an ultrasonic unit and Er: YAG laser compared to the conventional drilling. Moreover, the recovery of the patients in these two groups was more pronounced. The observed tissue changes proved to affect the follow-up tissue reactions in the postoperative period (p ≤ 0.05). DISCUSSION Based on the established effects on human bone by its in vivo cutting, it can be concluded that laser and ultrasonic bone surgery was a superior alternative osteotomy method in humans to conventional drilling.

Comparative Study of the Surgical Excision of Impacted Mandibular Third Molars Using Surgical Burs and an Erbium-Doped Yttrium Aluminum Garnet (Er:YAG) Laser. Cureus 2023; 15:e49816. [PMID: 38169690 PMCID: PMC10758536 DOI: 10.7759/cureus.49816] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 12/02/2023] [Indexed: 01/05/2024] Open
Abstract
Background The use of lasers has increased in the field of dentistry in recent years. However, in the field of oral and maxillofacial surgery, the use of lasers has been largely restricted to soft tissue, and less focus is placed on the use of lasers for hard tissues. Aim The present study aimed to comparatively evaluate the efficacy of a erbium-doped yttrium aluminum garnet (Er:YAG) laser for cutting the bone while removing the impacted mandibular third molar with the use of a surgical bur. Methods The study assessed 80 subjects undergoing removal of impacted mandibular third molars. The subjects were recruited from the Department of Oral and Maxillofacial Surgery, Luxmi Bai Institute of Dental Sciences and Hospital, Patiala, Punjab, India. They were randomly divided into two groups, each consisting of 40 subjects. Group I used an Er:YAG laser to remove the bone, while Group II used a surgical bur. Assessments and comparisons were made for complications, wound healing, trismus, edema, bleeding, and pain. Results The study examined the efficacy of the Er:YAG laser for cutting the bone and extracting the impacted mandibular third molars using a surgical bur in two groups of 80 patients each. When the laser was used in place of a surgical bur, Group I patients experienced less edema, bleeding, and discomfort; nevertheless, the difference was not statistically significant. Time taken by laser for bone cutting was significantly higher compared to the surgical bur. In Group I (laser), trismus existed for a longer time. For mouth opening, the preoperative mouth opening was comparable in the two groups with p = 0.87. Conclusion Pain, hemorrhage, and edema were lesser, and the time required for bone cutting was substantially longer in the laser group. Apart from these, laser-assisted intra-oral bone cutting should be preferred because of its less invasive nature, simpler procedure, and simpler osteotomy when compared to traditional surgical burs and also in anxiety-prone patients.

Abstract
BACKGROUND There are few research works with in-depth studies and direct simultaneous comparisons of the effects on tissue reactions and patients' recovery following in vivo conventional drilling, ultrasound- and laser-assisted osteotomy in humans. OBJECTIVE The current study aims to compare bone cutting duration, pain, swelling, and trismus in patients following surgical mandible third molar extraction by bone removal using three different osteotomes-a conventional rotary device, an ultrasonic unit, and an Er:YAG laser. METHODS A prospective, randomized three-group comparative clinical trial was performed. As an experimental setting for the study, аn open mandible third molar surgery was chosen because osteotomy is included in its protocol. Patients were divided into three groups according to the used device for bone removal. Bone cutting time intraoperatively, facial swelling, trismus, and pain on the first, second, and third postoperative days were assessed. The statistical analyses were performed using the SPSS v. 17.0-Kolmogorov-Smirnov test, one-way ANOVA, Student's t-test, Mann-Whitney test, and χ2 test. Statistical results were considered significant at p < 0.05 (confidence interval of difference, 95% CI). RESULTS Eighty patients (34 males and 46 females with an average age of 25.18 years) were included in the study. The average time for bone removal by the conventional low-speed device (4.95 min), by the ultrasonic unit (5.13 min), and by the Er:YAG laser (9.00 min) differed significantly (p = 0.001). The mean postoperative facial swelling showed a marked difference between the groups (p < 0.05), in favor of the laser and piezo groups. The osteotome proved to influence pain intensity not only immediately after surgery (p = 0.002), but also during the followed-up period (p = 0.001), again in favor of the two above-mentioned groups. No association was found between trismus and the osteotome used by the followed-up patients (p > 0.05). CONCLUSION Bone-cutting mechanism and the biological influence of the laser beam and ultrasound on living tissues proved to be favorable factors for patients' pain levels and tissue swelling postoperatively independent of the longer osteotomy duration compared to conventional drilling.

Abstract
Objective: The aim of this study is to investigate whether Er:YAG laser and piezosurgery methods can be an alternative to the conventional bur method. Background: The purpose of this study is to compare the postoperative pain, swelling, trismus and patient satisfaction between Er:YAG laser, piezosurgery device, and conventional bur methods that are used to remove bone barrier during extraction of the impacted lower third molar. Methods: Thirty healthy patients who have bilateral, asymptomatic, vertically impacted mandibular third molar teeth according to Pell and Gregory classification Class II and Winter Class B were selected. Patients were randomly divided into two groups. In 30 patients one side of the bony cover around the tooth was removed by the conventional bur technique, on the other side 15 patients were treated with the Er:YAG laser (VersaWave dental laser; HOYA ConBio) 200 mJ, 30 Hz, 4.5-6 W, noncontact mode, SP and R-14 handpiece tip, under air and saline solution, and 15 patients with the piezosurgery technique (VarioSurg Piezo; NSK) with frequency 20-100 kHz, 10-80% power range in Surgery (S), continuous mode, with SG17 and SG5 handpiece tip blade. Preoperative, 48th hour and 7th day measurements were made and recorded about pain, swelling, and trismus. At the end of the treatment, patients were asked to fill out a satisfaction questionnaire. Results: The pain observed at the postoperative 24th hour was statistically significantly lower in the laser group than in the piezosurgery group (p < 0.05). Only in the laser group swelling was seen with statistically significant differences between preoperative and postoperative 48th h (p < 0.05). Postoperative 48th h trismus value was seen as the highest in the laser group than others. Patient satisfaction was found to be higher in the laser and piezo technique compared with the bur technique. Conclusions: Er:YAG laser and piezo methods can be a good alternative to the conventional bur method when postoperative complications are compared. We believe that laser and piezo methods will be preferred for patients due to increased patient satisfaction. Clinical Trial Registration number: B.30.2.ANK.0.21.63.00/08 date: 28.01.10 no:150/3.

Abstract
PURPOSE Removal of impacted third molars, can be associated with complications such as pain, edema, trismus, that can increase the morbidity of this procedure. The purpose of this study is to determine whether the Er: YAG laser is effective in reducing pain, swelling and trismus compared to rotary instruments in removing impacted lower third molars (3 LM`s). METHODS For this systematic review the searches were carried out independently by 2 researchers and the articles were selected according to the inclusion and exclusion criteria previously established. The predictor variable was the study group (Er: YAG laser versus rotatory instruments). The main outcome was the analysis of post-operative pain, edema and trismus after third molars extractions. Data analysis included the risk of bias evaluation (RoB 2 Cochrane) and meta-analysis with random effects I2 based heterogeneity and 95% confidence. RESULTS In the initial results, 1,371 articles were found and 6 RCT were selected to compose this study. A total of 299, 3 LM`s were removed, 126 with the Er: YAG laser, 142 with a drill and 31 with a piezoelectric instrument. The results of this meta-analysis showed that in the laser group there was a significant reduction in edema (1.82 [CI95% = -3.06 to -0.57] cm (P = .004)) and complications (P = .0004), a slight reduction in pain after 2 days (P = .030) and there was no variation in trismus (P = .200) when compared to the drill group. The surgery and/or osteotomy time was shorter in the drill group. Only 1 study presented low risk of bias. CONCLUSIONS The Er: YAG laser has been shown to be effective in reducing edema, pain and complications in impacted lower third molar surgeries. however due to the lack of standardization in Er: YAG laser therapy, new controlled and standardized studies should be performed with the aim of proving the efficacy of this therapeutic modality.

Abstract
OBJECTIVE This study compared patient postoperative pain, swelling, and trismus after usage of rotary instruments, piezosurgery, and Er:YAG lasers in mandibular third-molar extraction. MATERIALS AND METHODS This prospective study was executed with class II and position B vertically impacted mandibular third molars. Patients were divided into three groups according to the osteotomy system used to remove retentive bone: rotary instruments, piezosurgery, and Er:YAG laser. Postoperative pain was evaluated using VAS questionnaires at 12 h, 24 h, 48 h, and 7 days after procedures. Trismus was evaluated by measuring the distance between the maxillary and mandibular incisors at maximum mouth opening, and comparing preoperative measurements with those for postoperative days 2 and 7. Analyses of swelling were carried out via a stereophotogrammetry system. Operation times were measured using a digital stopwatch from the initial incision to the final suture. RESULTS There were no statistically significant differences between the groups in terms of pain, trismus, or swelling (p > 0.05). Pain persisted more in the rotary instrument group 24 h later (0 ± 1.3; p = 0.001). The pain scores obtained after 48 h for the piezosurgery (1.81 ± 2.29) and rotary (2.2 ± 2.12) groups were observed at 24 h in the laser group (2.19 ± 1.52). The mean operation time was highest using the laser (19.1 ± 3.85 min; p = 0.001) and lowest using rotary instruments (9.88 ± 2.97 min; p = 0.001). CONCLUSION Piezosurgery and Er:YAG laser are good alternatives to rotary instrument systems in third-molar extraction, but both systems are slower than traditional rotary instruments.

Abstract
Background Reduction in postoperative complications is of vital considerations in impacted third molar teeth surgery. The aim of this study was to compare postoperative complications of impacted third molar surgeries for bone removal using laser, piezoelectric equipment, and conventional rotary instruments. Methods To address the research purpose, the investigator designed the prospective double-blind clinical trial study. The sample size was determined 20 (40 teeth) by sampling formula in any kind of operation. The data of patients were obtained in the different periods in terms of pain, trismus, swelling, ecchymosis, and patient's satisfaction and then analyzed using SPSS 20 software via paired t test and Wilcoxon and McNemar's tests. Results The pain immediately after surgery and 2 days and 7 days after surgery was higher in the laser group. The swelling immediately after surgery was more in the laser group but not significant. The amount of mouth opening immediately after surgery and 2 days and 7 days after surgery was significantly lower in the laser group than in the piezosurgery group. The total duration of surgery and duration of osteotomy were significantly longer in the laser group. The patient's satisfaction from surgery with piezosurgery was more than that with laser, but this difference was not significant. Conclusion Due to the rising demand for impacted wisdom tooth surgery, the present study suggests that hard tissue laser surgery and piezosurgery can clear the future of impacted molar surgery, and these approaches are more efficient in reducing postoperative complications compared to the conventional surgeries.

Abstract
Objective: To evaluate the effect of the Er,Cr:YSGG laser on healing of critical-sized calvarial defects (CSDs) in rats submitted to inhalation of cigarette smoke. Background: Smoking has been implicated with the delay in the bone healing after osteotomy procedures, then the use of the Er,Cr:YSGG laser for osteotomy in smokers could be an alternative to the conventional drills. Methods: One hundred animals were randomly allocated into four groups: trephine-the CSDs were made with a trephine drill in healthy rats; Er,Cr:YSGG-the CSDs were made with the Er,Cr:YSGG laser in healthy rats; Trephine-S-the CSDs were made with a trephine drill in rats exposed to cigarette smoke; and Er,Cr:YSGG-S-the CSDs were made with the Er,Cr:YSGG laser in rats exposed to cigarette smoke. The inhalation of cigarette smoke started 7 days before the surgical procedure until euthanasia (immediately, 7, 15, 30, or 60 days after the surgical procedure). A histometric analysis and a histological description were performed to evaluate (1) the residual linear lengths and bone formation in the CSDs; (2) the quality of bone healing. Results: The use of Er,Cr:YSGG laser induces more bone formation compared with the trephine in smokers; however, the closure of the CSD was only superior in the Er,Cr:YSGG-S group compared to the Trephine-S group at the 60-day period. Conclusions: The use of the Er,Cr:YSGG laser stimulated the bone repair process after osteotomy procedures in animals submitted to exposure of inhalation of cigarette smoke.

Assessment of Temperature Rise and Time of Alveolar Ridge Splitting by Means of Er:YAG Laser, Piezosurgery, and Surgical Saw: An Ex Vivo Study. BIOMED RESEARCH INTERNATIONAL 2016; 2016:9654975. [PMID: 27957502 PMCID: PMC5121450 DOI: 10.1155/2016/9654975] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/18/2016] [Revised: 06/06/2016] [Accepted: 10/13/2016] [Indexed: 11/18/2022]
Abstract
The most common adverse effect after bone cutting is a thermal damage. The aim of our study was to evaluate the bone temperature rise during an alveolar ridge splitting, rating the time needed to perform this procedure and the time to raise the temperature of a bone by 10°C, as well as to evaluate the bone carbonization occurrence. The research included 60 mandibles (n = 60) of adult pigs, divided into 4 groups (n = 15). Two vertical and one horizontal cut have been done in an alveolar ridge using Er:YAG laser with set power of 200 mJ (G1), 400 mJ (G2), piezosurgery unit (G3), and a saw (G4). The temperature was measured by K-type thermocouple. The highest temperature gradient was noted for piezosurgery on the buccal and lingual side of mandible. The temperature rises on the bone surface along with the increase of laser power. The lower time needed to perform ridge splitting was measured for a saw, piezosurgery, and Er:YAG laser with power of 400 mJ and 200 mJ, respectively. The temperature rise measured on the bone over 10°C and bone carbonization occurrence was not reported in all study groups. Piezosurgery, Er:YAG laser (200 mJ and 400 mJ), and surgical saw are useful and safe tools in ridge splitting surgery.
