Digital technology-assisted extraction of impacted maxillary third molar located between the furcation of maxillary second molar by root dislocation: a case report.

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.

Dentigerous Cysts in Children: Clinical, Radiological, and Healing Aspects.

Background and Objectives: Dentigerous cysts are one of the most frequent pathologies associated with unerupted or impacted teeth. Such cysts show a male predilection and a preference for the mandibular region. Also, they commonly occur in the second and third decades of life, with only 9% occurring in the first decade. The aim of this work is to apply and study the therapeutic algorithms developed for dentigerous cysts and their outcomes, from the early diagnostic stage to the complete healing phase of pediatric patients diagnosed with this medical condition. Materials and Methods: The study included 19 pediatric patients diagnosed with dentigerous cysts who underwent the enucleation and extraction or conservative attitude of the associated tooth. The bony healing was also followed-up 9 months after the surgery. Results: A higher incidence in the posterior area of the mandible and maxilla was observed, as well as a higher incidence in boys. The 9 months postoperative radiographic assessment showed that the bony defects were completely healed. Conclusions: A thorough understanding of the nature of the lesion backed by a good clinical history and by state-of-the-art radiographic and radiologic examinations can go a long way in helping the surgeon to choose the correct therapeutic approach and to ameliorate the medical condition in the best long-term interest of the young patient. The considered dentigerous cyst cases demonstrated that an early diagnosis and treatment of this pathology is followed by a responsive treatment.

Effect of force direction and impaction angulation during dilaceration impacted central incisor traction: a finite element analysis.

BACKGROUND: The effects of traction forces at different angles on impacted central incisors(ICI)with varying inverted angles (IA) may be different. The objective of this study was to analyze the biomechanical effects of different force directions (FD) on developmentally inverted ICI with multi-angle variations and to offer insights and guidance for the treatment of inverted ICI. METHODS: Three-dimensional finite element method was employed to simulate clinical scenarios of inverted ICI traction. As such, 0.2 N of force (direction: antero-superior angles of 90°, 100°, 110°, 120°, and 130° relative to the long axis of the inverted ICI crown) was applied to the inverted ICI with inverse angles (IA) of 40°, 30°, 20°, 10° and 0°. Inverted ICI apical displacement and Von Mises stress on periodontal ligament (PDL) and alveolar bone were compared. RESULTS: IA and FD showed minimal influence on the stress distribution in the PDL, as higher stresses were concentrated in the apical region. The higher stresses in the alveolar bone are focused on the cervical and apical regions of the tooth. In particular, IA exerts a more significant impact on stress distribution in the alveolar bone than FD. The influence of IA on the apical displacement of inverted ICI is larger than that of FD. CONCLUSIONS: To promote the health of the root and periodontal tissues, it is recommended to use an angle of 100°-110° relative to the long axis of the ICI crown when dealing with a large IA (> 20°) developmentally inverted ICI. Conversely, an angle of 110°-120° can be used.

Demographic and Radiographic Characteristics Associated with the Occurrence of Impacted Third Molars in Indonesian Patients: A Retrospective Study.

An impacted third molar is one of the most common abnormalities of the tooth position, impacting patients and their quality of life. Based on the impact and the invasive removal procedure, this study aimed to evaluate the characteristics of impacted third molars based on their radiographic features as well as their association with demographic characteristics. Outpatient dental records of the oral and maxillofacial surgery department of Hasan Sadikin Hospital, Bandung, Indonesia, from 1 January 2018 to 31 December 2019, were sorted, and relevant clinical and demographic data and panoramic radiographic examination results were extracted from these records. All data were then tabulated and analyzed by using SPSS version 29. As many as 3019 impacted third molars were identified. Our findings suggested the association between age to the occurrence of impacted third molars where patients aged between 17 and 29 years old showed high occurrences of impacted third molars. Male patients with impacted third molars are more likely to have multiple impacted third molars, while this risk decreases in females. Radiographic examination showed that the mesioangular position is the most common position for mandibular third molars. The variation in high occurrences of the impacted third molar is associated with several demographic factors.

[Preliminary discussion on the whole life-cycle management of wisdom teeth health].

The impaction rate of wisdom teeth is increasingly high, leading to more and more serious clinical problems. For a long time, the primary approach to managing wisdom teeth has been direct extraction, with a notable lack of systematic and diversified treatment methods. This article introduces, for the first time, the concept of whole life-cycle health management for wisdom teeth and suggests that the window for wisdom teeth life-cycle health management should be moved forward to the tooth germ stage. For tooth germs of wisdom teeth with severe risks, timely and necessary intervention should be administered. For normally erupting wisdom teeth, efforts should be made to maintain their health so they can function over the long term. For impacted wisdom teeth that have not caused related clinical symptoms, careful observation and cautious extraction should be considered. If necessary, techniques such as orthodontics and autotransplantation can be used to functionalize them. For impacted wisdom teeth that have caused clinical symptoms, functional oral surgical principles should be applied to reduce surgical trauma and prevent intraoperative and postoperative complications using advanced clinical techniques.

[A comparative study of a two-stage surgical approach combining coronectomy with microimplant anchorage traction for extraction of impacted mandibular third molars with different traction angles].

Objective: To establish a two-stage surgical procedure of impacted mandibular third molars (IMTMs) extractions assisted by coronectomy and microimplant anchorage traction and to investigate the influencing factors of root movement and the effects of different traction angles on the clinical outcomes. Methods: Fifty-three IMTM in contact with inferior alveolar nerve (IAN) that underwent tooth extraction in the Peking University School of Stomatology from January 2022 to June 2023 were included, with coronectomy and microimplant anchorage implantation in the first stage of the surgery, root traction was achieved with orthodontic elastic and microimplant anchorages by about 600 g of force, when the IMTM root was detached from IAN, a second surgery was performed to extract the residual root. The basic information of patients and M3M, data on the microimplant anchorage implantation and traction, imaging measurements, and complications were recorded and analyzed. Results: The movement distance of the residual roots was (1.80±0.92) mm, and the duration of traction was (32.9±7.9) d. Multiple linear regression analysis showed that the residual root movement distance was significantly correlated with age, gender, number of roots, traction angle, and depth of the distal bone defect of the second molar (P<0.05). The smaller the traction angle, the more significant the movement of the residual roots (P=0.044). In one case (1.9%, 1/53), the patient experienced abnormal sensation in the lower lip 16 days after traction. Conclusions: The two-stage surgical method of combined coronectomy with rapid traction technique to extract the IMTM allows for rapid movement of the residual root and reduces the risk of IAN injury. The efficiency of root movement can be accelerated by appropriately reducing the traction angle during surgery. The traction effect can be predicted based on indicators such as age, gender, number of roots and depth of distal bone defects of second molar.

Optimal tooth sectioning using a surgical handpiece and elevator: a finite element study of horizontally deeply impacted mandibular 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.

Retrospective analysis of the effects of impacted third molar on hematologic patients undergoing hematopoietic stem cell transplantation.

Objective: This study aimed to investigate the incidence, treatment status, and impact position of impacted third molars (ITM) and their effects on patients undergoing hematopoietic stem cell transplantation (HSCT). Methods: A retrospective analysis was conducted on the medical records of 454 patients who underwent HSCT, out of which 188 patients had ITM. The presence of ITM and its association with transplant-related infections and complications were recorded and analyzed. Results: Patients with ITM were significantly younger. The number of mandibular ITM was notably higher than maxillary ones, and the risk of pericoronitis in mandibular ITM was significantly higher than in maxillary ones. Out of 311 ITM in 188 patients, 25 were extracted before transplantation. The proportion of extraction and treatment for ITM with pericoronitis or caries was significantly higher than that for ITM without such problems. Moreover, patients with a history of pre-transplant pericoronitis had a significantly higher probability of developing tooth-related complications during transplantation, caused by pericoronitis in ITM compared to patients without a history of pericoronitis. Conclusion: Pre-transplant examination and treatment of ITM are essential, especially in cases with a history of pericoronitis. Oral intervention can significantly reduce the occurrence of tooth-related complications related to ITM during transplantation.

[Postoperative risk of bleeding after removal of third molars in healthy patients - a prospective observational clinical study]. / Nabloedingsrisico na verwijdering derde molaar bij gezonde patiënten; een prospectief observationeel klinisch onderzoek.

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.

Knowledge, attitudes, and practices among patients with combined dentition defect and non-functional impacted teeth toward tooth autotransplantation.

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. Targeted interventions should be implemented to improve the understanding and practice of TAT among patients with dentition defects.

Effect of hydrogen peroxide and hyaluronic acid in mouth rinse after third molar extraction: a triple-blind parallel randomized controlled clinical trial.

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.

Effect of platelet-rich fibrin on the recovery after third molar surgery: A systematic review and meta-analysis.

This meta-analysis aimed to elucidate the effects of platelet-rich fibrin (PRF) on the recovery of alveolar bone after surgical removal of the mandibular third molars. PubMed, Cochrane Library, Web of Science, and Embase databases were searched from the inception to February 2023 for relevant studies on the application of PRF after the extraction of impacted mandibular third molars, with the language limited to English. Literature screening was conducted by two independent researchers. The Cochrane risk-of-bias tool was adopted for quality evaluation, and Stata 15.0 was used for statistical analysis. A total of 33 randomized controlled trials were included in the present study. Following surgical removal of the mandibular third molars, 1139 tooth sockets were filled with PRF, while 1138 sockets were sutured after conventional saline irrigation. The meta-analyses showed that PRF can relieve pain [(RR 0.454; 95% CI 0.23, 0.891); (SMD -0.74; 95% CI -0.97, 0.52)], improve swelling (SMD -1.48; 95% CI -1.90, -1.06), alleviate trismus (SMD -0.35; 95% CI -0.51, -0.19), reduce dry socket (SMD -0.18; 95% CI -030, -0.05), and promote bone tissue healing (SMD 2.34; 95% CI 0.18, 4.51). The current study confirms that PRF can reduce some postoperative complications. Local application of PRF after lower third molar extraction is a viable method for relieving pain and swelling, reducing the incidence of dry socket and trismus, and increasing bone density. However, whether it can promote soft tissue healing remains unclear. For patients undergoing complicated surgical extraction, local application of PRF into the sockets might be a good option.

Central dentinogenic ghost cell tumor of the maxilla: a case report with new imaging findings and review of the literature.

A dentinogenic ghost cell tumor (DGCT) is a rare benign odontogenic tumor that commonly shows characteristics of solid proliferation and has a relatively high risk of recurrence after surgical treatment. We herein report a case of a central DGCT that occurred in the maxilla and resulted in bone expansion. This study highlights new imaging findings (particularly magnetic resonance imaging) along with histopathological observations. In addition, we conducted a review of the existing literature on this rare tumor. A 37-year-old man developed swelling around the right cheek. A benign odontogenic tumor such as ameloblastoma was suspected based on the imaging examination findings (including bone expansion and the internal characteristics of the tumor) on panoramic imaging, computed tomography, and magnetic resonance imaging. The lesion was surgically excised from the right maxilla. Postoperative histopathological examination led to a definitive diagnosis of central DGCT. The tumor comprised epithelial neoplastic islands, resembling ameloblastoma, inside tight fibroconnective tissue; masses of ghost cells and formation of dentin were also observed. We had suspected that the minute high-density region around the molars on the imaging examinations represented alveolar bone change; however, it represented dentin formation. This led to difficulty diagnosing the lesion. Although DGCT may present characteristic findings on imaging examinations, its occurrence is infrequent, and in some cases, the findings may include the presence or absence of an impacted tooth without obvious calcification. The present case suggests that we should consider the possibility of an odontogenic tumor with calcification when high-density structures are observed inside the lesion.

Feasibility and Preliminary Efficacy of α-Calcium Sulfate Hemihydrate in Socket Preservation: Protocol for a Pilot Randomized Controlled Trial.

BACKGROUND: Tooth extraction procedures often lead to bone resorption, which can have adverse effects on the dimensions of the alveolar ridge. Research has shown that socket preservation techniques using bone graft substitutes can effectively minimize early bone loss in such cases. α-calcium sulfate hemihydrate (α-CSH) has garnered significant attention as a potential bone graft material due to its favorable properties, including osteoconductivity, angiogenic potential, and biocompatibility. Considering these facts, we developed a preliminary protocol for applying α-CSH in addressing alveolar bone loss following tooth extraction. OBJECTIVE: This research's general objective is to evaluate the feasibility and initial effectiveness of α-CSH as bone-inducing graft material for socket preservation after tooth extraction. METHODS: This preliminary clinical trial will involve 30 fresh extraction sockets from individuals aged 18-35 years. The participants will be divided into 2 groups: one group will receive α-CSH graft material after tooth extraction for socket preservation, while the other group will not receive any graft material. Throughout the study, the participants will be closely monitored for safety measures, which will include clinical examinations, radiographic imaging, and blood tests. Radiographic imaging will be used extensively to assist the progress of bone formation. RESULTS: The study commenced enrollment in August 2022 and is scheduled to conclude post assessments and analyses by the end of 2023. The results of the study are anticipated to be accessible in late 2024. CONCLUSIONS: This clinical study represents the initial investigation in humans to assess the feasibility and efficacy of α-CSH in alveolar bone regeneration. We hypothesize that the inclusion of α-CSH can greatly expedite the process of bone formation within fresh sockets, resulting in a swift restoration of bone height without the disadvantages associated with harvesting autogenous bone graft.

Are There Differences in the Causes and Complications of Mandibular Third Molar Extraction in Older Patients Compared to Younger Patients?

BACKGROUND: Although most impacted third molars (ITMs) are extracted in the teens and early 20s, some undergo extractions after their 40s. It is unclear whether the reasons for extraction, the degree of impaction, and complications differ in patients in an older age group compared with a younger age group. PURPOSE: The purpose of this study was to measure the association between age and 1) reason for extraction and 2) postoperative complications. STUDY DESIGN, SETTING, SAMPLE: This was a retrospective cohort study of patients who had undergone surgical extraction of at least one mandibular ITM at a single institution. We excluded 1) age under 20 years, 2) follow-up period of less than 1 week, and 3) tooth extraction under general anesthesia. PREDICTOR VARIABLE: The primary predictor variable was age, classified into 3 groups (20s:20-29; 30s:30-39; over 40s: 40 and greater). MAIN OUTCOME VARIABLE(S): The primary outcome variables were the reason for extraction (prophylactic or symptomatic) and the presence of complications. The secondary outcome variable was type of complication (postoperative infection, dry socket, neurosensory disturbance, presenting pain over 1 month, retained root requiring secondary treatment). COVARIATES: The covariates were sex, laterality of ITM, and difficulty of extraction as measured by the difficulty index, a measure based on depth, orientation, and ramus relationship/space available, with a higher score indicating greater difficulty. ANALYSES: χ2 test was performed to analyze the association of categorical outcome variables and covariates. Level of statistical significance was set at P < .05. RESULTS: Of a total of 831 eligible subjects, there were 555 (66.8%), 159 (19.1%), and 117 (14.1%) in the 20s, 30s, and over 40s age groups, respectively. The percentage of symptomatic extraction of ITM was significantly higher in the over-40 age group compared with the 20s group (92.3 vs 69.4%, (P < .001). Complication rate also significantly differed between over 40s group and the 20s group (7.7 vs 1.8%, P < .001). Difficulty index and indications for ITM extraction were significantly different between groups (P < .001). CONCLUSION AND RELEVANCE: Symptoms, difficulty, and complications related to ITM increase at over 40 years of age. This should be taken into consideration during the joint clinical decision-making process with patients with ITM.

Treatment and genetic analysis of multiple supernumerary and impacted teeth in an adolescent patient.

BACKGROUND: Multiple supernumerary teeth, combined with numerous impacted teeth, can lead to various malocclusions, posing significant treatment challenges. While certain genes associated with syndromic cases of multiple supernumerary and impacted teeth have been identified, the etiologies of non-syndromic cases still largely remain elusive. CASE PRESENTATION: Here, we report a treatment of a 12-year-old boy who presented with 10 supernumerary teeth and 6 impacted teeth, accompanied by a genetic analysis to explore the underlying etiology. During the treatment, fifteen teeth were extracted, and various skilled techniques, including the closed-eruption technique and the application of by-pass arches, were utilized. Post-treatment, traction was successful for all the impacted teeth, without any tooth mobility or reduction in gingival height. Space closure, well-aligned teeth, and excellent functional occlusion were achieved. Furthermore, comprehensive genetic analysis was conducted through whole-exome sequencing on the patient and his parents, which revealed a potential link between the patient's numerous supernumerary teeth and abnormal mineralization. Notably, the p.Ser496Pro variant in the TCF7L2 gene was identified as a potential candidate variant in this patient. CONCLUSIONS: Overall, our findings not only report the treatment of a rare case involving multiple supernumerary and impacted teeth but also offer valuable insights into the molecular basis of supernumerary teeth.

The influence of finishing line and luting material selection on the seating accuracy of CAD/CAM indirect composite restorations.

OBJECTIVES: This study aimed to assess the seating accuracy of resin composite CAD/CAM overlay restorations, employing various preparation designs and luting materials (pre-heated composite (HC) or resin cement (RC)). METHODS: A human molar's STL file was utilized to create 100 3D-printed resin tooth replicas, randomly distributed into 5 groups (n = 20) based on finishing line preparation designs: 1) Rounded shoulder above the dental equator - DE (SA); 2) Chamfer above the DE (CA); 3) Butt joint above the DE (BJ); 4) Rounded shoulder below the DE (SB); 5) Chamfer below the DE (CB). Digital impressions were acquired for all replicas, and restorations milled using Tetric CAD (Ivoclar Vivadent). The restorations were luted with HC (Tetric Prime, Ivoclar Vivadent) or RC (RelyX Universal, 3 M). Seating accuracy was evaluated through digital scans during try-in without any luting agent and post-cementation using a 3D analysis software (Geomagic wrap, 3D Systems). Data were statistically analyzed using Two-Way ANOVA (p < 0.05). RESULTS: The type of luting material (RC vs HC), preparation design, and their interactions significantly impacted 3D seating of the restorations (p < 0.001). HC exhibited higer volumetric increase than RC. BJ and CA designs consistently demonstrated superior seating accuracy, irrespective of the luting material used. CONCLUSIONS: The utilization of pre-heated composite resin could negatively influence the seating of overlay restorations, probably due to its higher viscosity when compared to the resin cement. However, when HC is selected as luting agent, preparation designs lacking internal angles are recommended for enhancing the precision of overlays seating.

Evaluation of the effect of dental anxiety on vital signs in the order of third molar extraction.

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.
