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.

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.

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.

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 Odontogenic keratocyst (OKC) is a common odontogenic cyst, and it occurs more frequently in the mandible, with the posterior region of the dental arch, the angle, or the ramus being the most commonly affected sites. Odontogenic keratocyst occurring within the maxillary sinus is extremely rare, accounting for only about 1% of cases. CASE REPORT A 20-year-old female patient without any clinical symptoms underwent an oral examination, during which a dense dental shadow was identified within the maxillary sinus, surrounded by a low-density shadow. Physical examination revealed absence of the left maxillary third molar, with intact mucosa. The patient reported no history of tooth extraction. X-ray and cone-beam computed tomography revealed a high-density image within the left maxillary sinus, resembling a tooth and surrounded by a soft-tissue shadow, which exhibited a greater density in comparison to conventional odontogenic cysts. The initial diagnosis was odontogenic keratocyst in the maxillary sinus with an ectopic maxillary third molar. Surgical enucleation of the cyst and extraction of the impacted tooth were carried out utilizing the Caldwell-Luc approach. Histopathological analysis confirmed the presence of OKC. No significant recurrence was noted during the 6 months of follow-up. CONCLUSIONS Odontogenic keratocysts in the maxillary sinus with ectopic third molar are rare and may not have any symptoms in the early stage. Surgery can be performed using the Caroler-Luke approach to achieve ideal treatment results. In view of the high recurrence rate of OKC, close follow-up should be conducted after surgery.

This double-blind, randomised clinical trial aimed to find out whether there is a difference in the prevalence of neurosensory disturbance (NSD) between patients who received 2% lidocaine and those who received 4% articaine during inferior alveolar nerve blocks (IANBs). Patients who underwent third molar extraction were randomised into two groups. IANB was performed using 2% lidocaine in Group 1 and 4% articaine in Group 2. The occurrence of NSD was documented. Patients were visited within 48 hours and one week after the tooth was removed. The type of anaesthetic drug (4% articaine versus 2% lidocaine) was the study's predictive factor. A total of 2400 patients were studied in two groups (1200 in each group). The mean (range) age of the patients was 28.40 (18-44) years. Five patients (0.41%) in the lidocaine group and seven (0.58%) in the articaine group had NSD after injection (p = 0.77). The prevalence of NSD after IANB was no higher in the articaine group than in the lidocaine group.

OBJECTIVES: The aim of this study was to explore inflammation of soft tissue around the upper third molar as a prevalent cause of limited mouth opening, identify the clinical and radiographic features, and summarize the therapeutic effectiveness of tooth extraction. MATERIALS AND METHODS: A retrospective analysis of data from 264 patients with limited mouth opening over the last five years was performed. RESULTS: Among the 264 patients, 24 (9.1%) had inflammation of the soft tissue around the upper third molar, which was the second most common cause of limited mouth opening. Twenty-one of the twenty-four affected patients, with an average mouth opening of 19.1 ± 7.6 mm, underwent upper third molar extraction. Gingival tenderness around the upper third molar or maxillary tuberosity mucosa was a characteristic clinical manifestation (p < 0.05). The characteristic features on maxillofacial CT included soft tissue swelling around the upper third molar and gap narrowing between the maxillary nodules and the mandibular ascending branch. Post extraction, the average mouth opening increased to 31.4 ± 4.9 mm (p < 0.05), and follow-up CT demonstrated regression of the inflammatory soft tissue around the upper third molar. CONCLUSIONS: Inflammation of soft tissue around the upper third molar is a common cause of limited mouth opening. Symptoms of pain associated with the upper third molar and distinctive findings on enhanced maxillofacial CT scans are crucial for diagnosis. Upper third molar extraction yields favorable therapeutic outcomes. CLINICAL RELEVANCE: Inflammation of the soft tissue around the maxillary third molar commonly causes limited mouth opening, but this phenomenon has long been overlooked. Clarifying this etiology can reduce the number of misdiagnosed patients with restricted mouth opening and enable more efficient treatment for patients.

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.

This study compared the safety of general anesthesia (GA) and intravenous sedation (IVS) in patients who underwent extraction of one or more third molars. Data from 1260 patients (GA group, n = 1043; IVS group, n = 217) were retrospectively analyzed, including demographics, preoperative data, intraoperative hemodynamic parameters (blood pressure, heart rate, and oxygen saturation level), and medications administered intraoperatively and postoperatively. The incidence of intraoperative circulatory variations, surgery and anesthesia durations, postoperative complications, and medication use were assessed and compared. The GA group had longer anesthesia and surgery durations, a higher incidence of hypotension, and a higher frequency of postoperative analgesic use than the IVS group. Dexmedetomidine was the most frequently used sedative agent. The IVS group had a lower incidence of intraoperative hypotension but they had a higher need for vasopressors in the recovery room. Both anesthesia methods maintained satisfactory oxygen saturation levels and sufficient anesthesia throughout the procedure, but they showed different characteristics regarding the duration of surgery and anesthesia duration, hemodynamic stability, and postoperative analgesic needs. IVS may be preferable for patients at risk of cardiovascular complications such as hypotension or tachycardia during surgery.

OBJECTIVE: The study aimed to investigate the potential beneficial role of hydrogen peroxide (H2O2) and hyaluronic acid (HA) combination formulation in socket healing after third molar surgery. Biomaterials, including mouthwash formulations, were hypothesized to contribute to improved socket healing and reduced post-operative complications. PATIENTS AND METHODS: A triple-blinded parallel randomized controlled clinical trial was conducted at a single-center dental hospital in Milan, Italy. The trial included 114 patients who underwent extraction of impacted, partially erupted, and completely erupted third molars. Patients were randomly assigned to three parallel groups: Group 1 (H2O2 and HA), Group 2 (placebo), and Group 3 (0.2% chlorhexidine). The trial was registered at ClinicalTrial.gov (registration number NCT04438434). The main outcome measures included various parameters related to socket healing, such as pain, inflammation, swelling, plaque index, bleeding index, granulation tissue, suppuration, re-epithelialization, bleeding upon palpation, odor, and taste alteration. Patients were followed up for 7 days. RESULTS: All 114 enrolled patients completed the study, with no dropouts or loss to follow-up. The mean age of patients in the three groups differed (H2O2 and HA: 30.9±14.9; placebo: 27.6±13.1; 0.2% chlorhexidine: 23.05±10.16). Significant reductions (p<0.001) in visual analog scale (VAS) pain levels and other outcome measures were observed in the H2O2 and HA group compared to the placebo group. These findings suggest a positive effect of the H2O2 and HA combination on socket healing after the third molar surgery. CONCLUSIONS: The study concludes that the combination of hydrogen peroxide and hyaluronic acid can be considered a potential mouthwash with beneficial effects on socket healing following third molar surgery. However, additional clinical trials are recommended to validate its effectiveness further and provide additional evidence supporting its use in clinical settings. CLINICALTRIAL: gov: NCT04438434.

Antiphospholipid syndrome (APS) is a systemic autoimmune condition characterised by recurrent venous or arterial thrombosis and pregnancy complications, with persistent antiphospholipid autoantibodies. APS is often found in conjunction with other autoimmune diseases, such as systemic lupus erythematosus (SLE). SLE-associated APS patients may require dental procedures like tooth extractions. Due to the complex nature of this autoimmune disorder, perioperative management requires a comprehensive approach involving various medical specialists.These patients are frequently taking medications like anticoagulants, antiplatelet drugs, disease-modifying drugs and immunosuppressants. This medication regimen can increase their risk of postoperative complications, including bleeding, thrombosis, delayed healing and postoperative infections. Currently, there are no established guidelines for performing tooth extractions in individuals with SLE-associated APS.We report a case of SLE-associated APS with pericoronitis requiring surgical extraction. The purpose of this report is to offer practical recommendations for the perioperative management of dental procedures and alteration in medications used in such cases.

BACKGROUND: The distal aspect of the second molar (d-M2) often exhibits infrabony defects due to the adjacent third molar. Although the defects can be treated by guided tissue regeneration (GTR) after removing the third molar, the optimal timing remains uncertain following third molar removal in clinical decision-making. This study aimed to compare delayed and immediate GTR treatments to assist in clinical decision-making. METHODS: D-M2 infrabony defects with a minimum 1-year follow-up were collected and divided into three groups: Immediate GTR group, which underwent third molar extraction and received GTR simultaneously; Delayed GTR group, which underwent delayed GTR at least 3 months after third molar extraction; and Control group, which underwent only scaling and root planing during third molar extraction. The clinical and radiographic parameters related to the infrabony defect before GTR and post-surgery were evaluated using the Kruskal-Wallis test or one-way ANOVA, followed by post-hoc Dunn's test or the Bonferroni test for pairwise comparisons. RESULTS: A total of 109 d-M2 infrabony defects were assessed. No significant differences were found between the two GTR groups, although both of them showed significant reductions in infrabony defect depth: the immediate GTR group (2.77 ± 1.97 mm vs. 0.68 ± 1.03 mm, p < 0.001) and the delayed GTR group (2.98 ± 1.08 mm vs. 0.68 ± 1.03 mm, p < 0.001) compared to the control group. CONCLUSION: GTR can effectively improve d-M2 infrabony defects when the third molar is removed, whether simultaneously or delayed. Patients may experience less discomfort with immediate GTR treatment as it requires only one surgery.

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.

RATIONALE: Pyogenic spondylodiscitis is an infectious spinal disease that causes significant motor dysfunctions. Its diagnosis can be challenging owing to its rapid onset and nonspecific symptoms. PATIENT CONCERNS: A 79-year-old Japanese man with a history of type 2 diabetes mellitus and polymyalgia rheumatica presented to our department with tongue pain. Following partial glossectomy and wisdom tooth extraction under general anesthesia, on 10 postoperative day (POD) the patient developed right-sided abdominal pain and difficulty in walking. On 12 POD, the patient was admitted to a municipal hospital due to respiratory distress and paraplegia. DIAGNOSES: The patient was diagnosed with pyogenic spondylodiscitis and empyema. Blood tests revealed elevated C-reactive protein levels (36.5), white blood cell count (19,570), and neutrophil count (17,867). INTERVENTIONS: The patient received meropenem hydrate 3 g/2 days as empiric antibiotic treatment for acute infection. Upon admission to the emergency department on 16 POD, the lung abscess was drained, hemilaminectomy was performed. OUTCOMES: Blood cultures, sputum tests, and cultures from the thoracic and spinal abscesses drained during surgery revealed methicillin-sensitive Staphylococcus aureus. The infection was successfully managed, and the respiratory disturbance and inflammatory response improved. However, the lower half of the patient body remained paralyzed. Subsequently, the patient was transferred to a rehabilitation facility on 45 POD. The patient continued to undergo functional restoration training, gradually regained function, and eventually achieved the ability to walk with grasping gait. LESSONS: This is the first case report of S aureus causing pyogenic spondylodiscitis and empyema due to blood stream infection from a post-oral surgical wound. Pyogenic spondylodiscitis arising from a secondary hematogenous infection is difficult to diagnose and can lead to severe functional impairment. Prompt and appropriate diagnosis and treatment based on detailed patient interviews, additional blood tests, and computed tomography are essential.

A 60-year-old man was referred to an oral and maxillofacial surgeon with discomfort caused by pressure on the left-hand side of the maxilla. Examination revealed a very elevated third molar in contact with the orbital floor and infundibulum, and, possibly, a follicular cyst. On account of the threat to the orbital floor, it was first decided to decompress the cyst and place an in situ drain. After 4 months, the tooth and cyst could be removed and the diagnosis of a follicular cyst was confirmed.Auteursinformatie.

Removal of third molars in healthy patients is considered a procedure with a low risk of bleeding. However, exactly how low the incidence of postoperative bleeding is remains unclear due to the heterogeneity of available studies. To determine the exact postoperative risk of bleeding after the removal of third molars in healthy patients, a prospective observational multicentre study was conducted. A total of 1,035 patients with complete follow-up was included. Of these, 329 patients reported subsequent bleeding, but did not consult their attending physician. A total of 15 patients visited the hospital, 8 of whom required minimally invasive (re)treatment. No hospitalizations were necessary. There was a large difference between the incidence of postoperative bleeding reported by patients and postoperative bleeding requiring clinical examination and/or treatment. To reduce this difference in future, patients should be given detailed information about what degree of postoperative bleeding is considered normal after removal of a third molar.

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.

It is urgently necessary to clarify the effect of extraction of impacted mandibular third molar (IMTM) on the periodontal tissue of adjacent second molars (ASMs). In this study, the ASM periodontal condition and pathogenic microbes were assessed before IMTM extraction and at 1, 4, 8 and 12 weeks postoperatively. Based on the inclusion and exclusion criteria, our study revealed that IMTM extractions adversely affected distal ï¼ periodontal probing depth (dPPD), attachment loss (dAL), plaque index (dPLI) and bleeding on probing (dBOP) within 8 weeks, but these indices gradually normalize after 12 weeks. The subgingival pathogens near the ASMs distal surface, Porphyromonas and Pseudomonas, were significantly increased postoperatively. Moreover, relevance of ASMs clinical indices and subgingival microbes after IMTM extractions was found. In contrast to the situation in chronic periodontitis, the effects of IMTM extraction on dPPD, dAL, dPLI and dBOP of ASMs were mainly correlated with Pseudomonas. Additionally, while the IMTM extractions have adverse distal periodontal indices of ASMs within 8 weeks and increase subgingival pathogens, the modified triangular flap (MTF) had fewer distal periodontal indices and less Pseudomonas. Compared to the traditional envelope flap and triangular flap, the MTF benefits the periodontal health, which could be considered as the priority option for IMTM extractions.
