RESUMO

Aim: To compare the microleakage of Cention N, a subgroup of composite resins with a resin-modified glass ionomer (RMGI) and a composite resin. Methods: Class V cavities were prepared on the buccal and lingual surfaces of 46 extracted human molars. The teeth were randomly assigned to four groups. Group A: Tetric N-Bond etch-and-rinse adhesive and Tetric N-Ceram nanohybrid composite resin, group B: Cention N without adhesive, group C: Cention N with adhesive, and group D: Fuji II LC RMGI. The teeth were thermocycled between 5°-55°C (×10,000). The teeth were coated with two layers of nail vanish except for 1 mm around the restoration margins, and immersed in 2% methylene blue (37°C, 24 h) before buccolingual sectioning to evaluate dye penetration under a stereomicroscope (×20). The data were analyzed by the Kruskal-Wallis and Wilcoxon tests (α=0.05). Results: Type of material and restoration margin had significant effects on the microleakage (p<0.05). Dentin margins showed a higher leakage score in all groups. Cention N and RMGI groups showed significant differences at the enamel margin (p=0.025, p=0.011), and for the latter group the scores were higher. No significant difference was found at the dentin margins between the materials except between Cention N with adhesive and RMGI (p=0.031). Conclusion: Microleakage was evident in all three restorative materials. Cention N groups showed similar microleakage scores to the composite resin and displayed lower microleakage scores compared with RMGI

RESUMO

OBJECTIVES: This prospective study was performed to evaluate whether the distal-triangular flap was a practical alternative surgical approach for extracting mandibular third molars. METHODS: Sixty participants with impacted mandibular third molars were randomly divided into three groups: group A, distal-triangular flap; group B, Szmyd flap; and group C, envelope flap. The impacted third molars were extracted by the corresponding flapping method. During a three-month follow-up observation after the extraction, the postoperative pain, swelling, mouth opening, and periodontal status were recorded and analyzed by ANOVA and chi-square tests. RESULTS: The 60 participants had successful extraction and 3-month follow-up observation. No participant suffered from postoperative infections, lower lip disorder, or tongue sensory disorders. No statistical differences were found in the postoperative symptoms and signs of the three flap designs, such as postoperative pain, swelling, mouth opening, and periodontal status (P>0.05). CONCLUSIONS: The distal-triangular flap was as safe and reliable as the Szmyd and envelope flaps but more advantageous because of its convenient operative field exposure and low requirement for the patient's mouth opening. Thus, the distal-triangular flap is one of the alternative flap options for extracting impacted mandibular third molars.

RESUMO

OBJECTIVES: This study aims to analyze the effectiveness of platelet-rich fibrin (PRF) in mandibular third molar extraction and provide suggestions for alleviating postoperative complications. METHODS: Pubmed, EMBASE, Web of Science, and SinoMed were searched electronically on February 2020. Randomized controlled trials focusing on PRF usage in mandibular third molar extraction were included. Reviewers assessed the risk of bias in the included literature and extracted data independently using the criteria recommended by the Cochrane Collaboration. Meta-analysis was performed using RevMan 5.3 and STATA 13.0. RESULTS: Twenty-one studies were included, comprising 991 patients who had mandibular third molar extraction. The topical application of PRF effectively reduced pain after extraction [MD=-12.06, 95%CI (-21.42, -2.71), P=0.01], attenuated post-extraction swelling [MD=-1.42, 95%CI (-2.41, -0.44), P=0.005], and promoted soft tissue hea-ling [MD=0.66, 95%CI (0.34, 0.99), P<0.000 1]. PRF significantly reduced trismus and alveolar osteitis (P<0.05). However, data could not prove whether PRF has any significant positive effect on bone healing compared with the control group (P>0.05). CONCLUSIONS: Limited clinical evidence indicates that applying PRF after mandibular third molar extraction could reduce pain, swelling, trismus and the occurrence of dry socket and promote soft tissue healing. However, the effect of PRF on bone healing requires further large-scale randomized controlled trials and unified measurement criteria.

RESUMO

BACKGROUND: An impacted tooth is a tooth which does not reach the occlusal plane even after two-thirds root formation. Conditions associated with impacted teeth include trismus, cystic lesions, and cervical caries of second molars. The objective of this study was to evaluate the occurrence of carious lesions in the distal aspect of the mandibular second molar and its association with the presence of mandibular third molars. METHODS: A cross-sectional study was conducted from September 2018 to September 2020. Approval was taken from the Institutional Review Committee with reference number 90/77/78. Orthopantomograms of patients aged 18 years or older were studied. Information on age, gender, mandibular second and third molars were recorded. Convenient sampling was done. Statistical analysis was done using Statistical Package for Social Sciences version 21. RESULTS: A total of 626 radiographs were studied of which mesioangular impaction (35.3%) was the most prominent type and followed by horizontal impaction, causing distal caries in second molars. The age group between 20-40 years and female gender had the higher prevalence of distal caries in second molar teeth. There was a significant correlation between gender and cavity existence (p=0.00), between impaction and existence of decay (p=0.00), and depth of impaction with cavity formation (p=0.004). CONCLUSIONS: A total of 31.8% of the patients with impacted mandibular third molars had distal cervical caries in second molars. Mesioangular type, female gender, type A were the prominent factors associated with distal caries in second molar teeth due to impacted third molars.

RESUMO

We here describe the story of a young man who developed a major pneumomediastinum after the removal of a wisdom tooth. The patient was hospitalized in the intensive care unit for continuous monitoring and for the administration of prophylactic antibiotic therapy to avoid infectious complications. Pneumomediastinum after dental procedures has already been reported and its management, although simple, remains subject to major complications if inadequately treated.

RESUMO

INTRODUCTION: Third molar impaction is a common patient complaint in dentistry. Common symptoms are localized pain, swelling, bleeding, and difficulty in mouth opening. Since dental students deal with patients early in their education, for better skill, they should have knowledge of various teeth impactions. Hence, the objective was to find out the knowledge of impacted teeth among undergraduate dental students of a medical college. METHODS: A descriptive cross-sectional study was conducted among bachelor in dental surgery students of a medical college from November 30, 2020 to April 3, 2021. Data collection was done by convenience sampling after receiving ethical clearance from Institutional Review Committee (Reference 1208202006). A structured questionnaire in Google Forms was sent to 221 participants via Viber. Out of 213 responses received, 144 were analyzed in Excel after discarding for duplication and other errors. Descriptive statistics such as mean, standard deviation, frequency, and percentage were analyzed. RESULTS: Out of the total of 144 participants, only 81 (56.3%) (47.89-91.4 at 95% Confidence Interval) had known about the term 'impacted teeth' before joining Bachelor in Dental Surgery course. The source of information was mostly the internet 27 (18.8%) followed by dentist 23 (16%). Most students 116 (80.6%) were familiar with third molar impactions, 62 (43.1%) knew about types of impacted teeth/impaction, and 100 (69.4%) were aware of the complications of not removing impacted teeth. CONCLUSIONS: Dental students should be provided with appropriate 'impacted teeth' education supported by practical experience. More detailed information regarding impacted teeth should be included in the curriculum for better understanding.

RESUMO

PURPOSE: The present study aimed to assess differences in postoperative morbidity between prophylactic and symptomatic third molar removals, and to assess the effect of age on the recovery of the patient. METHODS: Patients admitted for third molar removal were prospectively followed up four times during treatment in context of the M3BE study. Data were collected through pre-, peri and postoperative surveys (days 3 and 10). Uni- and multivariable logistic regression was used to assess the probability of postoperative symptoms of discomfort on day 3 and day 10 according to several patient- and surgery-related predictive factors (age, gender, indication for removal, method of extraction, anesthesia and number of extracted maxillary and/or mandibular third molars). RESULTS: In total, 6010 patients with a mean age of 25.2 (± 11.2) underwent 6347 surgeries to have 15,357 third molars removed. Frequently observed symptoms of postoperative discomfort were pain, trismus and swelling, all of which were transient in nature with steep decreases from postoperative days 3 to 10. Increasing age was associated with an enhanced risk of persistent pain, trismus and swelling and a significantly higher risk of iatrogenic injury to the inferior alveolar nerve. Symptomatic indications for removal were more common in patients over age 25 years, but these pre-existing pathologies did not compromise the postoperative recovery process. Other factors related to postoperative morbidity were female gender, intraoperative osteotomy and the number of extractions. CONCLUSION: The results of this study suggest that there are convincing patient- and surgery-related factors that favor timely third molar removal, preferably before the age of 25, especially in order to avoid persistent morbidity and nerve complications.

RESUMO

The most common oral and maxillofacial surgical procedure in adolescents is excision of impacted third molars. Adolescent patients should be evaluated for third molars starting around age 16 years unless symptomatic at an earlier age. The dental examination should include panorex imaging to assess development, pathologic condition, and possibility of eruption versus impaction. Various classification systems are available to identify the position and difficulty of the proposed surgical procedure. Retained impacted teeth increase the patient's risk of various morbidities including recurrent infection, damage to adjacent teeth, cysts and other lesions, and unexplained pain.

RESUMO

AIM: Most of the intra- and postoperative patient discomfort related to complex mandibular third molar (M3M) extraction is proportional to the invasiveness of the surgery. This can be minimized through the support of dynamic navigation (DN) technology, which can be successfully applied in dental implantology. Materials and methods: Three patients, one female (aged 25 years) and two males (aged 18 and 51 years, respectively) underwent the DN-supported extraction of partially impacted M3Ms with a flapless approach that required minimal bone removal. The patients' discomfort and the speed of recovery were considered to be proof of the quality of the adopted procedure. RESULTS: No postoperative discomfort such as pain or swelling was recorded in the immediate postoperative period, and no complications were reported within a month of the surgery. No medications were prescribed. The procedure lasted no longer than 20 min in all cases. CONCLUSION: Using DN technology, the real-time 3D monitoring of the clinical situation in each surgical phase enabled the surgeon to avoid soft tissue detachment as well as limit bone loss and intraoperative bleeding, thanks to a precise multi--section of the tooth and important nearby anatomical structures, respectively.

RESUMO

BACKGROUND: Juxta-apical radiolucency (JAR) has been presented as a radiographic sign, suggestive of the IAN injury through third molar surgery. This study aimed to evaluate the relation of JAR with IAN injury in cone-beam computed tomography (CBCT) images and to determine whether the presence of JAR is related to tooth angulation, proximity to the mandibular canal, position to the IAN, and thinning of the cortical plates. METHODS: Of an initial sample of 545 mandibular third molars, a total of 75 JAR+ and 75 JAR- teeth were evaluated by CBCT. We assessed the relationship between the presence of JAR in cone-beam computed tomography (CBCT) images and the presence of IAN injury after mandibular third molar surgeries. Moreover, we investigated whether the presence of IAN injury is related to tooth angulation, proximity to the mandibular canal, position to the IAN, and thinning of the cortical plates. Descriptive statistics, Chi-square test, and Fisher's exact test were performed for statistical analysis. RESULTS: A significant relationship was found between JAR and temporary IAN injury (P = 0.036). However, there was no case of permanent IAN injury. IAN injury showed no significant relationship with the tooth angulation, position to IAN and proximity to the mandibular canal, lingual cortical plate thinning, sex, and age. CONCLUSIONS: JAR is generally in contact with the mandibular canal, and some degree of cortical thinning can be found in most cases. In this study, JAR was significantly related to temporary IAN injury. JAR may increase the risk of nerve injury during the surgical removal of third molars.

RESUMO

BACKGROUND: How to prevent pain after the extraction of impacted teeth is a serious challenge for all patients. The purpose of this clinical trial was to investigate whether pre-emptive low dose of etoricoxib can reduce postoperative pain in patients undergoing third molars surgery. METHODS: Patients were randomised to receive etoricoxib 60 mg or placebo 30 min before surgery. Post-operative pain was recorded using a visual analogue scale during 24 h within the post-operative period. The total dose of ibuprofen rescue intake was recorded. Kaplan-Meier curves and log-rank analyses were used to evaluate the proportion of patients without rescue analgesic. RESULTS: Scores for the post-operative pain in the etoricoxib group were significantly lower than those in the placebo group during first 12 h (p < 0.05). The number of patients without analgesic rescue medication was significantly lower in the etoricoxib group than in the placebo group. The average amount of rescue medication in the etoricoxib group (0.4 ± 0.9 dose) was lower than that in the placebo group (1.1 ± 0.9 doses, p = 0.004). Etoricoxib resulted in the long-term survival of patients without rescue analgesic (p < 0.001). CONCLUSIONS: This study revealed that etoricoxib has a substantial pre-emptive analgesic effect, resulting in the reduced use of analgesics after third molar removal. TRIAL REGISTRATION: Registered on ChiCTR1900024503. Date of Registration: 13/07/2019.

RESUMO

Background: The aim of the present study is to compare the dental anxiety levels between two outpatient clinics. Methods: Two hundred and seventy patients treated in two different clinics of minor oral surgery and dental extraction polyclinic in the Dental Faculty of Eskisehir Osmangazi University were included in the study. The impacted third molar surgery group and conventional dental extraction group consisted of 101 and 169 patients, respectively. The Modified Dental Anxiety Scale (MDAS) and Dental Fear Scale (DFS) were used to measure anxiety levels in patients treated in both clinics. Tests were made in an isolated room preoperatively. The differences in anxiety levels according to education status and gender were also evaluated. Results: The impacted third molar surgery group showed a significant increase in dental anxiety measured with DFS questionnaire (p < 0.05). However, MDAS revealed that there was no difference between anxiety levels between the impacted third molar surgery and conventional dental extraction groups (p > 0.05). There was also no difference in anxiety levels between patients with different education status (p > 0.05). Female patients demonstrated higher levels of anxiety in both MDAS and DFS indexes (p < 0.05). Conclusion: Dental anxiety may be higher in patients treated with impacted third molar surgery compared with conventional dental extraction. The education status of patients may not affect dental anxiety. Female patients may show increased levels of dental anxiety in conventional dental and impacted third molar extractions.

RESUMO

BACKGROUND: To evaluate the predictive capacity of orthodontists and oral maxillofacial surgeons (OMFSs) in anticipating the process of impaction or eruption of lower third molars (L3Ms) through the examination of serial panoramic radiographs. METHODS: Sixty-eight lower third molars (L3Ms) were analyzed in 34 orthodontically treated patients without extraction. Twenty-seven OMFSs and 27 orthodontists were randomized in order to analyze the radiographs. Initially, the evaluators issued the prognosis for the L3Ms in XR1, a posterior for the XR1 + XR2. Concordance of the diagnosis was examined using Kappa statistics, and the differences between the groups of evaluators were examined using the chi-square test at p<0.05. RESULTS: When examining XR1 in cases where the teeth erupted spontaneously, the prognostic accuracy rate for OMFSs and orthodontists was similar, 63 and 65.7%, respectively (p=0.19). When evaluating XR1 + XR2, the accuracy among orthodontists (60%) was similar to that reported for XR1 (p=0.19), while OMFSs presented a reduction in the accuracy (55.3%, p<0.0001). When the L3Ms remained impacted, accuracy in XR1 was lower than in spontaneously erupting L3Ms, although similar between OMFSs (50.1%) and orthodontists (49.1%). Furthermore, for impacted L3Ms, when examining XR1 + XR2, the OMFSs presented a significant higher accuracy (71.8%, p <0.0001). CONCLUSIONS: Orthodontists and OMFSs seem unable to predict spontaneous eruption or impaction of the lower third molars from single or longitudinal x-rays. When adding a second longitudinal x-ray, orthodontists and more significantly OMFSs tend to indicate more extractions.

RESUMO

Background: The purpose of this meta-analysis was to assess the clinical efficacy of etoricoxib in comparison with traditional NSAIDs for postoperative pain after third molar surgery. Methods: The quality of studies found in PubMed and Google Scholar was evaluated with Cochrane Collaboration's risk of bias tool. Data on total consumption of rescue analgesics, number of patients using rescue analgesics, global assessment of study treatments, and adverse effects were extracted exclusively from high-quality clinical trials. Each meta-analysis was performed with the Review Manager Software 5.3 for Windows. Results: The qualitative analysis showed that etoricoxib has better analgesic activity when compared with ibuprofen (2 clinical trials) and diclofenac (1 clinical trial). A similar analgesic efficacy between etoricoxib and nonselective Cox-2 NSAIDs was informed in 3/8 studies (2 compared to ibuprofen and 1 to naproxen sodium). Moreover, the number of patients requiring rescue analgesics in the postoperative period showed a statistical difference in favor of etoricoxib when compared to NSAIDs. Conclusion: Etoricoxib significantly reduces the number of patients needing rescue analgesics compared to NSAIDs after third molar surgery.

RESUMO

Data sources The review carried out electronic searches using several online databases through November 2018, namely PubMed, Virtual Health Library, Cochrane Library and Scopus. Terms searched for on these databases included third molar, flap and variations thereof. A grey literature search was also conducted.Study selection In total, 2,455 articles were identified,1,449 being duplicates. Additionally, 1,006 articles remained for assessment which, with clear exclusion criteria listed, was reduced to 20. From the 20 incorporated into the review, 18 articles were utilised for meta-analysis. Three of the researchers were involved in assessing the articles after research management software was used to remove the aforementioned duplicates. A Cohen's kappa index was calculated to confirm inter-rater consistency using 10% of the articles.Data extraction and synthesis Data extraction followed the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidance.Results From their systematic review and meta-analyses, the authors found that flap design had no effect on common post-operative complications including pain, trismus, dehiscence, or osteitis. The triangular flap did, however, have greater post-operative ecchymosis but reduced periodontal probing depth on day seven when compared to the envelope flap in mandibular third molar surgeries.Conclusions Third molar surgery is carried out across all facets of dentistry, including general and specialised. Further studies must be carried out that look specifically at these variables utilising randomised controlled trials so a consensus can be achieved across the profession of which flap is of superior design.

RESUMO

The objective of this study was to study the incidence of type of impaction of mandibular third molars based on the classifications of Pell and Gregory and Winter, which included angulation of the tooth and level of the occlusal surface of the third molar with respect to the second molar, respectively, in a sample of Saudi population in central region. In this retrospective study, orthopantomograms (OPGs) of 17760 patients were examined, who were reported by the Dental University Hospital (DUH) at King Saud University, Riyadh, Saudi Arabia, between the years 2016 and 2020. Out of 17760 radiographs, 2187 (12.31%) patients presented with at least one impacted third molar. Out of which, 1337 (7.52%) patients had bilateral impaction and 850 (4.78%) patients had unilateral impaction (p < 0.001). No gender predominance was noted in the impaction status (p > 0.05). In bilateral impaction, 671 were male (50.2%) and 666 were female (49.8%). Among unilateral impaction, 394 (46.4%) were male and 456 (53.6%) were female. Mesioangular angulation was the most common pattern of impaction (65%) followed by vertical angulation in both bilateral and unilateral impactions. Level A impaction was found to be highest in both bilateral and unilateral impactions which are 48.02% and 54.0%, respectively (p < 0.05). Our study highlights mesioangular impaction and level "A" as the most frequently encountered angulation and level of impaction in impacted teeth. This study result provides us useful data regarding the radiographic status of mandibular third molars in the population of Saudi Arabia.

RESUMO

The aim of this descriptive ex vivo study was to evaluate qualitatively the depth of pit and fissures (P&F) of the enamel in human mandibular third molars. Fifty (n=50) extracted human mandibular third molars were cleaned and disinfected. All tooth surfaces were coated with nail varnish except for a 1-mm margin around the periphery of the occlusal surface. The teeth were immersed for 48 hours at 37 °C in 1% methylene blue dye solution prepared in artificial saliva. After cleaning, the crowns were separated from the root at the cementoenamel junction and subsequently sectioned longitudinally in buccolingual direction at the location of the central fossa. All sections were examined using a stereoscopic microscope and photographed. The images were downloaded on a computer. The length of penetration of the P&F was recorded using the following scoring system: C1: P&F extended to half of the enamel thickness; C2: P&F extended beyond half of the enamel thickness without reaching the dentine-enamel junction; C3: P&F extended to the dentine-enamel junction. For pits, C1, C2 and C3 were observed in 35, 9 and 6 teeth, respectively, while for fissures, C1, C2 and C3 were observed in 15, 18 and 17 teeth, respectively. The P&F detected in the samples extended to the deepest portions of enamel, quite frequently reaching the enamel-dentine junction. Clinicians should recognize that even if pits and fissures are not clinically obvious, they penetrate deep into the enamel and frequently reach the dentine-enamel junction. Effective treatment is recommended to block access to P&F, thus preventing ingress of bacteria.

For pits, C1, C2 and C3 were observed in 35, 9 and 6 teeth, respectively, while for fissures, C1, C2 and C3 were observed in 15, 18 and 17 teeth, respectively. The P&F detected in the samples extended to the deepest portions of enamel, quite frequently reaching the enamel-dentine junction. Clinicians should recognize that even if pits and fissures are not clinically obvious, they penetrate deep into the enamel and frequently reach the dentine-enamel junction. Effective treatment is recommended to block access to P&F, thus preventing ingress of bacteria.

RESUMO

Due to the frequent development of non-infectious complications after surgical removal of the third lower impacted tooth, many techniques are used to reduce their severity. Among them is the technique of applying platelet-rich fibrin to the post-extraction alveolus. The study included 90 consecutively enrolled patients. Eligible patients were randomly assigned to two groups: patients with and without platelet-rich fibrin introduced into the postoperative alveolus. Pain, swelling, trismus, and temperature were evaluated after the procedure. Pain intensity was significantly higher in the control group than in the study group at 6 h, 1, and 3 days after surgery. PRF application did not significantly affect the intensity of swelling. Body temperature was significantly higher in the control group than the study group on day two after surgery. The trismus was significantly higher in the control group than in the study group at one, two, and seven days after surgery. Application of the PRF allows for a faster and less traumatic treatment process. It will enable for speedier recovery and return to active life and professional duties.

RESUMO

BACKROUND: This study was designed to analyse the value of preoperative Cone Beam CTs (CBCT) prior to the surgical removal of complex lower third molars. Furthermore, the aim was to assess injuries to the inferior alveolar nerve (IAN) bundle and postoperative neurological disorders depending on the position of the lower third molar and the inferior alveolar nerve bundle. METHODS: In this retrospective examination preoperative Cone Beam CTs and Orthopantomographs (OPT) of 324 patients were analysed concerning the location of the lower third molars in relation to the mandible and the inferior alveolar nerve bundle. Surgery protocols of all patients who underwent the surgical removal of at least one complex lower third molar were analysed concerning patient data, length of surgery, intraoperative haemorrhage, intraoperative exposure of the inferior alveolar nerve bundle, postoperative swelling and postoperative neurological disorders. The data was then compared to data from international studies. RESULTS: In all 324 patients a permanent neurological damage was not found. Temporary neurological damage was recorded in 13 cases (2.6%). A caudal nerve position with no measurable distance to the root of the lower third molar was associated with the highest risk of a temporal neurological damage. A vestibular touching nerve route also correlated with postoperative sensitivity impairment. If a mesioangulation (Winter) or a Pell and Gregory Type IIIC appears in the OPT, risk of neurological damage is at its highest. CONCLUSIONS: Three-dimensional radiographic imaging, in our patient group, does not significantly affect the risk for complications during the surgical removal of complex lower third molars. Therefore, it should only be utilized for risk assessment, especially in cases of symptom-free lower third molars. A preoperative orthopantomogram still can be accepted as standard for radiographic imaging. An intraoperative exposure of the IAN bundle does not necessarily predict simultaneous neurological damage. Exposure of the IAN bundle is no indication for a discontinuation of the surgery.
