RESUMEN
BACKGROUND: There is a general consensus among dental professionals regarding the extraction of impacted third molars in the presence of clinical symptoms. However, there is less agreement on the management of asymptomatic third molars. The objective of this study is to compare the perspectives of oral surgeons and orthodontists regarding the indications for the extraction of asymptomatic third molars. It is possible that healthcare professionals from different specialties may approach the extraction of these teeth in different ways. METHODS: In this cross-sectional study, a web-based questionnaire has been employed to collect data by inquiring about the reasons why participants prefer the extraction of asymptomatic third molars. Descriptive statistics were employed to evaluate the data obtained. The level of significance was set at P < 0.05. RESULTS: Prophylactic extraction of partially impacted molars was more favored among the participants (P < 0.05). The orthodontists preferred prophylactic extraction due to the risk of late anterior dental crowding (LADC); however, the oral surgeons preferred pre-pregnancy extractions (P < 0.05). The extraction decision for partial impaction was higher in females when the risk of distal caries was considered. For fully impacted ones, it was higher in males when the risk of caries and pericoronitis were considered (P < 0.05). CONCLUSIONS: Orthodontists preferred extraction because of the risk of LADC and caries, while oral surgeons focused on preventing pericoronitis, pathology, focal infection, and symptoms during pregnancy. This divergence between the participants may inform the guidelines for prophylactic management of third molars. These findings may be pertinent in gender medicine. CLINICAL RELEVANCE: This study has been enlightening for departments to consult each other before the extraction of a patient's asymptomatic third molar.

BACKGROUND Surgical extraction of impacted mandibular third molars is the most commonly performed procedure in oral surgery; its associated complications include sensory nerve damage, swelling, and trismus. This study aimed to evaluate the effects of hyaluronic acid (HA) on healing of the socket following extraction of the lower impacted third molar tooth in 40 dental patients. MATERIAL AND METHODS This prospective, double-blind, randomized, controlled study was carried out on 40 adult healthy patients indicated for surgical removal of bilateral impacted mandibular third molars with equal surgical difficulty (moderate surgical difficulty according to the Koerner index. Patients with right mandibular third molars were included into the study (HA) group and those with left mandibular third molars were included into the control group. Surgical removal of impacted teeth was performed at different times for each patient for proper measurement of postoperative clinical variables, including pain, swelling, and mouth opening. RESULTS Postoperative pain evaluation results using the visual analog scale (VAS) showed reduced pain levels at all observation periods. Postoperative swelling peaked in intensity within 12-48 hours, resolving between the 5th and 7th days, and there was no significant difference in pre- and postoperative measurements of interincisal opening between both groups (P>0.05). CONCLUSIONS We found that intra-socket application of hyaluronic acid after surgical extraction of impacted mandibular third molars promoted normal wound healing, and there was a clinical benefit of reduced postoperative pain and swelling.

BACKGROUND-OBJECTIVE(S): This randomized, split-mouth study aimed to compare postoperative complications following the surgical extraction of impacted lower third molars using piezosurgery versus conventional rotary instruments. MATERIALS AND METHODS: Twenty-one patients, aged 18-35 years, with bilaterally and symmetrically impacted lower third molars, were randomly assigned to undergo extraction using piezosurgery on one side and conventional rotary instruments on the other. RESULTS: The piezosurgery method required a longer operation time. However, it resulted in quicker resolution of postoperative swelling by the 7th day compared to the conventional method, where swelling persisted longer. Mandibular angle-tragus measurements were significantly higher with the conventional method on the 1st, 3rd, and 7th postoperative days. Although mouth opening decreased significantly after piezosurgery, it returned to preoperative levels by the 7th day, outperforming the conventional method. Postoperative pain was notably higher with the conventional method during the first four days but showed no significant difference from the 5th day onward. Alveolar bone healing was significantly better with piezosurgery at the 3rd and 6th months. Temporary paresthesia occurred in one patient from the conventional group, resolving within four weeks. Neither method resulted in alveolar osteitis. CONCLUSION(S): Within the study's limitations, piezosurgery demonstrated a reduction in postoperative discomfort, suggesting its advantage in enhancing patient recovery following lower third molar extractions. CLINICAL SIGNIFICANCE: Piezosurgery, when used appropriately, can reduce postoperative complications compared to conventional methods. Clinicians should be aware of its indications, benefits, and potential challenges. Trial registration This study was registered as a clinical trial to the ClinicalTrials.gov, and the registration ID is NCT06262841 ( https://clinicaltrials.gov/study/NCT06262841 ).

BACKGROUND: Alveolar Bone loss occurs frequently during the first six months after tooth extraction. Various studies have proposed different methods to reduce as much as possible the atrophy of the alveolar ridge after tooth extraction. Filling the socket with biomaterials after extraction can reduce the resorption of the alveolar ridge. We compared the height of the alveolar process at the mesial and distal aspects of the extraction site and the resorption rate was calculated after the application of HA/ß-TCP or synthetic co-polymer polyglycolic - polylactic acid PLGA mixed with blood to prevent socket resorption immediately and after tooth extraction. METHODS: The study was conducted on 24 extraction sockets of impacted mandibular third molars bilaterally, vertically, and completely covered, with a thin bony layer. HA/ß-TCP was inserted into 12 of the dental sockets immediately after extraction, and the synthetic polymer PLGA was inserted into 12 of the dental sockets. All sockets were covered completely with a full-thickness envelope flap. Follow-up was performed for one year after extraction, using radiographs and stents for the vertical alveolar ridge measurements. RESULTS: The mean resorption rate in the HA/ß-TCP and PLGA groups was ± 1.23 mm and ± 0.1 mm, respectively. A minimal alveolar bone height reduction of HA/ß-TCP was observed after 9 months, the reduction showed a slight decrease to 0.93 mm, while this rate was 0.04 mm after 9 months in the PLGA group. Moreover, the bone height was maintained after three months, indicating a good HA/ß-TCP graft performance in preserving alveolar bone (1.04 mm) while this rate was (0.04 mm) for PLGA. CONCLUSION: The PLGA graft demonstrated adequate safety and efficacy in dental socket preservation following tooth extraction. However, HA/ß-TCP causes greater resorption at augmented sites than PLGA, which clinicians should consider during treatment planning.

BACKGROUND: The purpose of the study was to compare the efficacy of the use of 0.2% chlorhexidine irrigation and the oral antibiotics for the prevention of postoperative complication like pain, trismus, swelling and infection after the surgical extraction of IMTM. MATERIAL AND METHODS: A randomised, double blinded clinical trial was planned with two equal groups. Patients were randomly divided into two groups using computer-generated codes with an allocation ratio of 1:1. Group I (Control): Standard preoperative and postoperative systemic oral antibiotics and Group II (Study): No systemic antibiotics and Chlorhexidine irrigation local delivery. The primary outcomes evaluated were postoperative pain, mouth opening, swelling and infection. The secondary outcome variables were the number of analgesics and antibiotics taken by the patient in the postoperative period, the satisfaction of the patient and adverse events, were followed up regulary for 7 days postoperatively. RESULTS: A total of 84 patients, divided into two equal groups participated in the study. In intergroup comparison of swelling, the difference was non-significant on postoperative day (POD) 1 and 7, except for POD 3, where it showed significantly lower results in the antibiotic group (p = 0.012). However, there was no significant difference in pain found between both groups at any of the postoperative time points, and the study group had a lesser need for rescue analgesics than the control group. A statistically significant difference in incidence of dry socket was observed (p = 0.03) and gastrointestinal adverse symptoms, but it showed insignificant results for wound dehiscence and pus discharge. Also, patient satisfaction was higher in the study group. CONCLUSIONS: both antibiotics and localised delivery demonstrated comparable results in terms of swelling, pain and trismus. However, with lesser adverse events, the localised chlorhexidine delivery with curved tips outperformed the antibiotic group.

OBJECTIVES: The aim of this study was to compare leukocyte and platelet-rich fibrin (L-PRF) and photobiomodulation (PBM) applications, which have been repeatedly reported to be superior to control groups, in terms of pain, soft tissue and bone healing in tooth extraction sockets. MATERIALS AND METHODS: This double-blind, randomized clinical study was completed with 34 patients, who had an indication for extraction of their bilaterally impacted teeth. The right and left teeth of the patients were randomly divided into L-PRF and PBM groups. L-PRF group was treated with the blood product centrifuged for 12 min at 2700 rpm, and the PBM group was treated with a diode laser at different points for 60 s with a wavelength of 940 nm in repeated sessions. Postoperative pain was evaluated using Visual Analogue Scale (VAS), soft tissue healing with Landry Index (LI), tissue healing in the distal region of mandibular second molar by probing depth measurement, and bone healing via panoramic x-ray using the Image J program. RESULTS: No statistically significant difference was found for any variable compared between the groups. CONCLUSION: L-PRF and PBM applications provide similar support in the healing of extraction sockets. Nevertheless, the advantages and disadvantages of both methods determine their usage areas. CLINICAL RELEVANCE: While L-PRF is advantageous in the early healing of extraction sockets, PBM may be preferred in terms of bone trabeculation in the long term.

BACKGROUND: Limiting postoperative edema, pain, trismus, and infection is crucial for smooth healing. This prospective, controlled clinical trial investigated and compared the effectiveness of dexamethasone and hyaluronidase in relieving these complications. METHODS: In groups Ia and IIa, 8 mg of dexamethasone and 150 IU of hyaluronidase were administered following the removal of impacted teeth, respectively. The contralateral sides (groups Ib and IIb) were determined as control groups. Edema, pain, trismus, and infection were clinically evaluated on the 1st, 2nd, 3rd, and 7th postoperative days. RESULTS: 60 patients were enrolled in the study. Hyaluronidase provided significantly more edema relief than dexamethasone on the 1st, 2nd, 3rd, and 7th postoperative days (P = 0.031, 0.002, 0.000, and 0.009, respectively). No statistical difference was found between dexamethasone and hyaluronidase in VAS and rescue analgesic intake amount values for all time points. Hyaluronidase was more effective in reducing trismus than dexamethasone on the 2nd and 3rd postoperative days (P = 0.029, 0.024, respectively). Neither of the agents significantly increased the postoperative infection rate. CONCLUSIONS: Hyaluronidase can be selected when postoperative excessive edema and trismus are anticipated. Dexamethasone may be a cost-effective option if postoperative pain control is merely targeted. TRIAL REGISTRATION: This trial was registered in the Clinical Trials Protocol Registration and Results System (ClinicalTrials.gov identifier number: NCT05466604) on 20/07/2022.

Background and Objectives: The aim of this study was to investigate the efficacy of a single preoperative dose of deflazacort on pain, swelling, and trismus after impacted lower third molar surgery. Materials and Methods: This randomised, prospective, double-blind, split-mouth clinical study included 26 healthy individuals with bilaterally impacted lower third molars. Group 1 was given a placebo (single-dose vitamin C tablet), and group 2 was given a single 30 mg dose of deflazacort 1 h prior to surgery. Pain was evaluated using the visual analogue scale for 1 week postoperatively. Oedema (in mm) and trismus (in mm) were evaluated preoperatively and on postoperative days 2 and 7. The Mann-Whitney U test was applied for group analyses. p values < 0.05 were considered statistically significant. Results: Postoperative pain scores were significantly lower in the deflazacort group at the 6th and 12th hours after surgery (p < 0.05). There were no significant differences in trismus between the groups at any time point (p > 0.05). There was less oedema in the deflazacort group on postoperative days 2 and 7, without any statistically significant difference (p > 0.05). Conclusions: A single preoperative dose of 30 mg deflazacort was found to be clinically effective in reducing pain and oedema after extraction of impacted lower third molars.

BACKGROUND: Patients presenting with partially impacted lower third molars (M3) have a higher likelihood of experiencing angle fractures while simultaneously decreasing the risk of condylar fractures. However, the specific biomechanical mechanism responsible for this occurrence remains unclear. Moreover, there is an ongoing debate regarding whether the removal of M3s might actually increase the risk of condylar fractures. This study aimed to evaluate how the presence of M3s influences mandibular fractures resulting from blows to the symphysis and lateral mandibular body, and to determine the indication for extracting M3s in such cases. METHODS: Models of the mandible with a partially M3-impacted model (M3I), M3-extracted model (M3E), and M3-absent model (M3A) were generated using a computer. A traumatic blown force of 2000 N was applied to the symphysis and the right body of the mandible. Von Mises and principal stresses were analyzed, and failure indexes were determined. Two cases of mandibular linear fractures were chosen for model verification and interpretation. RESULTS: When force was applied to the symphysis, the condylar region exhibited the highest stress levels, while stress in the mandibular angle region was much less regardless of the M3 state. On applying the force to the right mandibular body, stress in the condylar region decreased while stress in the mandibular body increased, especially in the blown regions. Impacted tooth or cavity formation post-M3 extraction led to uneven stress distribution on the blown side of the mandible, increasing the risk of mandibular angle fractures. In cases where M3 was absent or the extraction socket had healed, stress from lateral traumatic blown force was evenly distributed along both the inner and outer oblique lines of the mandible, thereby reducing the risk of mandibular fractures. CONCLUSIONS: The reduced risk of condylar fractures in patients with partially impacted lower M3s and mandibular angle fractures is mainly due to lateral blows on the mandible, which generate less stress in the condylar region than blows on the mandibular symphysis, rather than being caused by the M3 itself. Extraction of the lower M3 can decrease the risk of mandibular fractures, with a minor influence on condylar fractures.

OBJECTIVE: The aim of the study is reducing the risks of surgical injury to the inferior alveolar nerve, by taking into account individual topographic and anatomical features, improving diagnostic methods, and techniques for removing retinated teeth with a close fit to the mandibular canal. MATERIAL AND METHODS: An examination was conducted in the Department of Surgical Dentistry (CBCT/OPG) and surgical treatment of 223 patients, with a close fit of the roots of the retinated lower third molar to the mandibular canal. Microslips of teeth with roots intact during removal (n=96) of the main group and the control group (n=52) were prepared with a Micromet Remet manual petrographic machine. The sections were carried out along the longitudinal axis of the tooth with the capture of the area of close fitting of the nerve, the teeth from the control group were sawed longitudinally along the axis of the root. The measurement of the macroanatomic features of the roots was carried out with a micrometer (MCC-MP-100 0.001 electronic «CHEESE¼, manufactured in the Russian Federation), measurements of the thickness of dentine and cement tissues on macroglyphs were carried out using a microscope calibration ruler with an accuracy of 0.01 mm. RESULTS: In the main group, three types of attachment of the mandibular canal to the root of the third molars were distinguished: 20 (96) cases of inter-root attachment of the mandibular canal, 42 (96) apical, 34 (96) lateral (buccal and lingual). A number of anomalies in the structure of the roots of the third molars have been revealed, which are a factor in injury to the neurovascular bundle of the mandibular canal during tooth extraction. The surface of the roots, as well as the microscopes of the tooth sections adjacent to the mandibular canal, were studied under a microscope. CONCLUSION: A number of specific anomalies of the roots of retinated third molars formed by root dilaceration, thinning of cement tissues, hypercementosis, which are formed at the site of the mandibular canal.In the presence of a deep indentation on the root of the tooth, as well as in the presence of areas of apical hypercementosis in the form of a «spike¼, the probability of nerve injury during tooth extraction increases many times, which must be taken into account when removing retinated third molars.

BACKGROUND: This 20-year retrospective study aimed to evaluate the treatment methods used in patients with impacted maxillary permanent canines and to determine the occurrence of ankylotic and resorptive processes and their association with potential risk factors. METHODS: The cohort consisted of 351 consecutive Caucasian patients (120 males and 231 females, mean age 18.4 and 19.9 years, respectively) with 420 impacted maxillary permanent canines. CT and CBCT findings were subsequently confirmed during surgery. Statistical analyses were performed by the generalized linear models, Pearson x2 and Fisher exact tests using the statistical programs R and Statistica v. 14. RESULTS: A total of 273 (65.0%) impacted canines were aligned in the dental arch by orthodontic traction after surgical exposure, this treatment was predominant in patients under 20 years of age. Surgical extraction was performed in 115 (27.2%) impacted canines and was more common in older patients. Ankylotic changes were recorded in 61 (14.5%) impacted canines. The probability of ankylosis increased with age, particularly after the patient's 20th year of life (p < 0.001). Patients were 1.2% likely to develop ankylosis at age 15 years, 4.3% at age 20 years, 14.1% at age 25 years, and 96.8% at age 45 years. Invasive cervical root resorption (ICRR) was found in 8 (1.9%) canines. In 4 canines (1.0%), root ankylosis in addition to ICRR was observed. In contrast to ankylosis, whose frequency of occurrence increased with age, the occurrence of ICRR resulting from PDL damage during surgery was more typical in younger patients. Canines in a high position above the root apices of the adjacent teeth, with a horizontal inclination of the longitudinal axis, with the crown located deep in the center of the alveolar bone and with labiopalatal position, should be considered critically impacted canines with a high risk to failure of orthodontic traction. CONCLUSION: In conclusion, the treatment of impacted canines depends mainly on the age of the patient, and the position and inclination of the longitudinal axis of the impacted tooth. To select an adequate treatment method, we recommend CBCT examination, which allows a precise analysis of the position of impacted canines.

The aim of this proposal is to (1) review the current literature, (2) shed light on the importance of creating universally accepted guidelines, (3) provide help and guidance in the decision-making process with regard to the removal of mandibular third molars (M3Ms), and (4) reduce the risk of exposing the patient to unnecessary harm and complications due to the inappropriate removal or retention of M3Ms.It is obvious that the indications for the extraction of M3Ms will continue to be an area of controversy and strong debate. The evidence for or against prophylactic extraction is ambivalent; there is evidence to accept or reject the stance against prophylactic extraction in some specific cases, and there are published articles to support both opposing views. The available guidelines on the extraction of third molars are limited in number, and are mostly tailored to fit specific settings or countries. There are no available guidelines that might be widely used to help in the decision-making process for the international community. We hope this proposal will constitute an important first step toward creating universally accepted guidance.

Distalization of mandibular molars comes with significant challenges, especially in adult and young adult patients. In selected cases, third molar extraction procedures offer the opportunity to place miniplates for anchorage to distalize mandibular molars, providing additional solutions to the traditional extraction of premolars or a single incisor. This approach can be of special interest to adult patients, who may have life commitments and time restraints that limit traditional orthodontic and surgical treatment options, and it can improve the efficiency of dental care. This case series describes 3 clinical scenarios in which miniplates were placed with minimal invasiveness during the removal of impacted third molars, offering the patients nontraditional orthodontic treatment options. Awareness of these options is essential for general dentists so that they can explain all treatment possibilities and provide appropriate referrals to patients with impacted third molars.

OBJECTIVES: To conduct a finite element analysis of the impact of different variables on tooth sectioning efficiency and trauma to surrounding tissues when utilizing high-speed surgical handpieces and elevators. METHODS: CBCT data from the horizontally impacted third mandibular molar (M3M) of a patient were utilized to establish digital models of the M3M, adjacent M2M, and surrounding bone. To simulate tooth sectioning, a 3D finite element model was established with the following variables: remaining tooth tissue thickness (1-5 mm), tooth section fissure width (1-3 mm), elevator depth in fissure (2-6 mm), elevator position (buccal, lingual, central), elevator width (2-5 mm), and application of force (rotating, levering). Using this model, the distribution of stress on the M3M and the surrounding tissue was assessed while measuring tooth sectioning efficiency and trauma to the surrounding tissue. RESULTS: Factors associated with uniform stress at the site of sectioning included thin (≤ 3 mm) remaining tooth tissue, appropriate fissure width (~ 2 mm), a wide (≥ 4 mm) elevator, and central elevator positioning. Levering the elevator yielded greater stress on the M3M than rotating force. Greater sectioning efficiency was associated with increased stress placed on the distobuccal side of M2M. CONCLUSIONS: Tooth sectioning efficiency can be improved by adjusting the high-speed surgical handpiece and elevator. However, it is important to remain attentive to the trauma to which adjacent teeth are exposed during this process. CLINICAL SIGNIFICANCE: These results offer guidance for approaches to improving operator efficiency and reducing trauma to surrounding tissues during tooth sectioning.

OBJECTIVES: This study aims to compare the sedative effects of remimazolam and midazolam during impacted tooth extraction to provide a comfortable sedation treatment for patients with dental anxiety. METHODS: A prospective randomized controlled trial was conducted, in which 60 patients undergoing intravenous sedation for mandibular impacted third molar extraction were evenly divided into either the remimazolam or midazolam group. Prior to receiving a nerve blocker, the patients were sedated with remimazolam or midazolam. Various parameters were recorded and analyzed, including onset time, awakening time, recovery time, modified dental anxiety scale (MDAS) scores before and after surgery, patient-doctor satisfaction levels, postoperative side effects within 24 hours, heart rate (HR), and mean arterial pressure (MAP) at different time points. RESULTS: Compared with the midazolam group, patients in the remimazolam group demonstrated significantly shorter onset, awakening, and recovery times as well as lower postoperative MDAS scores and higher levels of patient-doctor satisfaction. Fewer postoperative side effects were reported in the remimazolam group, although the differences were not statistically significant. CONCLUSIONS: The use of remimazolam demonstrates faster onset and recovery, superior efficacy in reducing dental anxiety, and enhanced satisfaction among patients and doctors, thereby presenting distinct advantages for sedation treatment for patients with dental anxiety.

BACKGROUND: Tooth autotransplantation (TAT) is a surgical procedure involving the extraction of a tooth from one location and its subsequent transplantation into another alveolar socket within the same individual. This innovative treatment approach holds significant promise. Nonetheless, the potential recipients exhibit a limited level of awareness and understanding of this procedure. This study investigated the knowledge, attitudes, and practices (KAP) among patients with combined dentition defects and non-functional impacted teeth toward TAT. METHODS: This web-based cross-sectional study was conducted between December 2022 and February 2023 at one hospital. A self-designed questionnaire was developed to collect demographic information of the patients and assess their knowledge, attitudes, and practices toward TAT. RESULTS: A total of 533 valid questionnaires were collected. The mean knowledge, attitude, and practice scores were 5.55 ± 2.38 (possible range: 0-10), 26.82 ± 2.46 (possible range, 8-40), and 27.45 ± 7.40 (possible range, 9-45), respectively. CONCLUSION: The participants had insufficient knowledge, negative attitudes, and passive practices toward TAT.

BACKGROUND: Dental anxiety is a prevalent concern affecting patients undergoing various dental procedures, particularly surgical interventions. Understanding the impact of patients' anxiety levels on their physiological responses during dental surgeries, such as third molar impaction surgery, is crucial for optimizing patient care and outcomes. Therefore, this study aimed to investigate the effect of patients' anxiety levels on vital signs during third molar teeth impaction surgery. METHODS: A cross-sectional study was conducted, including 45 randomly selected, healthy patients. Demographic information was recorded after obtaining consent from the patients prior to surgical intervention. Preoperative anxiety levels were determined using the Modified Dental Anxiety Scale (MDAS). Pupil measurements were taken from the patients before surgery, at 10 min after the surgery began, and at 10 min after the surgery ended. Systolic (SBP) and diastolic (DBP) blood pressure, pulse rate, temperature, and haemoglobin oxygen saturation (SpO2) values were recorded. RESULTS: The MDAS test results were statistically significantly higher in women compared to men (p < 0.001). Positive correlations were observed between MDAS score and both preoperative pulse rate (r = 0.344, p = 0.021) and SpO2 level during the operation (r = 0.462, p = 0.001). However, no significant correlations were found between MDAS and DBP (p = 0.575), SBP (p = 0.176), fever (p = 0.238), or pupil diameter (p = 0.338). CONCLUSIONS: Third molar impaction surgery induces anxiety in adult patients 20 years and older. Vital sign monitoring provides information about the patient's emotional state, both before and during the procedure. Since anxiety causes changes in vital signs during dental procedures, it is important to follow these findings to have an idea about the general condition of the patients.

Most of the maxillary impacted third molars are located in the maxillary tuberosity, where the vision and operation space are limited. This paper reports a case of surgical extraction of the left maxillary horizontal superhigh impacted third molar, which is located between the roots of the adjacent teeth and is closely related to the maxillary sinus. The digital simulation technology was used to reconstruct a three-dimensional visual image of the patient's maxilla, related teeth, and other adjacent anatomical structures to assist in finding the optimal surgical method accurately. Root dislocation before the crown not only protects the roots of the adjacent tooth, but also reduces the risk of maxillary sinus lining damage or perforation during operative procedures, improves the efficiency of the operation, and reduces surgical trauma, which conforms to the concept of minimally invasive surgery and provides a new idea and experience for the clinical extraction of such maxillary impacted third molars.
