Abstract
INTRODUCTION A simple tooth extraction method usually involves using elevators and forceps to remove the tooth easily. In contrast, a surgical extraction method requires utilizing a straight handpiece to facilitate the tooth extraction, either removing bone or sectioning the tooth into pieces. OBJECTIVE In this research, we aim to diagnose a tooth radiographically before extraction and determine certain factors to observe which extraction method might be more feasible, either simple or surgical. METHODOLOGY This study followed a retrospective cross-sectional study design. The x-ray radiographs (periapical (PA) or panoramic) were collected from the R4 system in the university dental hospital for data collection. Different radiographic influencing factors were measured, such as bone density, bone level, endodontic involvement (RCT/post and core), crowned or remaining root, and root morphology. Statistical associations were performed using SPSS (IBM Corp., Armonk, NY) with a one-way ANOVA test. RESULTS There were 62 cases with 47 simple and 15 surgical extractions. There was a non-significant (p>0.05) association between the measured factors and the extraction method, either simple or surgical tooth extraction. Although bone density measurements showed a slight tendency toward PA lesions and simple tooth extraction. CONCLUSION There was no significant association between the factors and extraction methods. Future research is required to determine whether or not preoperative radiographic evaluation can influence the decision for the tooth extraction method.

Mandibular third molar extraction: perceived surgical difficulty in relation to professional training. BMC Oral Health 2023; 23:485. [PMID: 37452399 PMCID: PMC10349451 DOI: 10.1186/s12903-023-03131-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Accepted: 06/13/2023] [Indexed: 07/18/2023] Open
Abstract
BACKGROUND Establishing the level of surgical difficulty pre-operatively is an essential step in ensuring correct treatment planning. This study set out to determine whether the knowledge and experience acquired by dentists who had received different levels of training influenced, firstly, the perceived levels of difficulty of a variety of cases of mandibular third molar (MTM) extraction and, secondly, the perceived difficulty deriving from a series of factors (patient-related factors, anatomical and radiographic factors, operative factors). METHODS This cross-sectional, descriptive, observational study took the form of a survey. Using a visual analog scale (VAS), participants evaluated both the perceived difficulty of 30 cases of MTM extraction described by means of digital panoramic radiographs and the perceived difficulty deriving from a series of factors conditioning MTM extraction. The results underwent statistical analysis with SPSS Statistics 28.0 software. Non-parametric tests (Mann Whitney test for independent samples and the Kruskal-Wallis test) were applied. RESULTS A total of 389 surveys were available for analysis. Dental practioners with no surgical training saw the intervention as presenting greater difficulty. Professionals with postgraduate training in oral surgery considered patient-related factors more important than operative factors, in contrast to dentists who had not received oral surgery training. CONCLUSIONS Dental training has a signficant influence on the perceived difficulty of MTM extraction and also affects opinions about which factors have greater or lesser influence on surgical difficulty.

Effect of manuka honey socket dressing on postoperative sequelae and complications following third molar extraction: A randomized controlled study. J Craniomaxillofac Surg 2023:S1010-5182(23)00072-0. [PMID: 37164834 DOI: 10.1016/j.jcms.2023.05.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 03/03/2023] [Accepted: 05/03/2023] [Indexed: 05/12/2023] Open
Abstract
To evaluate the effect of manuka honey on the healing of mandibular third molar extraction sockets. This was a prospective randomized study at a tertiary health institution in Lagos, Nigeria. All extractions were transalveolar, using the distobuccal bone guttering technique. Participants were randomized into two study groups. Group A underwent intrasocket application of manuka honey, after which sockets were completely closed using the mucosal flap, while participants in group B underwent mucosal flap closure of the socket without application of manuka honey. The primary outcome was healing of the extraction socket at 7 days postoperatively. The secondary outcomes measured were postoperative sequelae, namely pain, swelling, and trismus on postoperative days 1, 3, and 7, and socket healing complications - specifically inflamed socket, infected socket, and alveolar osteitis. In total, 112 participants completed the study, with 56 participants per group. There were no significant differences in demographic variables between both groups. On the 7th day postoperatively, 26.8% of participants in group B had an unhealed extraction site, compared with 10.3% of participants in group A (p = 0.029). A significant difference was observed between pre- and postoperative pain scores in both study groups (p = 0.001). A comparison of postoperative mean facial swelling between the two groups showed no statistically significant differences on all the review days (p = 0.66). The difference in postoperative socket healing complication rate between both groups was statistically significant (χ2 = 4.747, p = 0.029). Within the limitations of the study it seems that the application of manuka honey appears to aid earlier healing of the third molar extraction socket, with a significantly lower frequency of complications. Therefore, the application of manuka honey is recommended whenever appropriate.

Assessment of Difficulty in Mandibular Third Molar Surgery by Lambade-Dawane-Mali's Index. J Oral Maxillofac Surg 2023:S0278-2391(23)00210-0. [PMID: 36924791 DOI: 10.1016/j.joms.2023.02.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 02/19/2023] [Accepted: 02/20/2023] [Indexed: 03/18/2023]
Abstract
PURPOSE The evaluation of mandibular third molar (M3) difficulty is extremely important. This study aims to measure the association between preoperative Lambade-Dawane-Mali's (LDM) M3 difficulty index and postoperative assessment of difficulty score. MATERIAL AND METHODS This prospective cohort study included patients with impacted M3 reported to the Department of OMFS, RRK Dental College, Akola, from 2017 to 2022. The preoperative surgical difficulty was estimated using the predictor, LDM index with scores, easy (15-25), moderate (25-30), and difficult (>30). The postoperative surgical difficulty was analyzed with the primary outcome variable, total time intervention measured from the beginning of incision to the final suturing, wherein extraction was classified as easy if time (<15 minutes), moderate (15-30 minutes), and difficult (>30 minutes). The secondary outcome variable, Modified Parant's Scale (MPS), defines four levels of difficulty required for extraction of M3: Easy I (forceps extraction), Easy II (requiring osteotomy), Difficult III (coronal sectioning), and Difficult IV (complex extraction). Data were analyzed using agreement between LDM difficulty with three established criteria (time, MPS, Pederson index) and were assessed with Cohen's Kappa statistics. McNemar's test for paired data was used to assess concordance between two criteria of evaluation with a P-value <.05 was considered statistically significant. RESULTS The study sample included 1000 patients with a mean age of 26.7 ± 7.6 years and 456 (45.6%) females. Preoperative LDM difficulty assessed postoperatively by MPS indicated 99% were correctly identified by LDM preoperatively to have difficult and 99% easy outcomes. Inter-criteria agreement and Kappa statistics suggested a positive Kappa value (κ) and statistically significant agreement between the LDM index with perioperative time (κ = 0.8930), MPS (κ = 0.6488), and Pederson index (κ = 0.4920) at P-value 0.0001. Pair-wise comparisons of LDM criteria with perioperative time, MPS, and Pederson scale were assessed by McNemar's test, which evaluated concordance between the two criteria. CONCLUSION Postoperative evaluation of surgical difficulty in M3 extraction was strongly correlated with preoperative variables in the LDM difficulty-scoring index. Preoperative evaluation helps in envisaging the difficulty, planning surgical management, and helps in better time scheduling.

Incidence of lingual nerve damage following surgical extraction of mandibular third molars with lingual flap retraction: A systematic review and meta-analysis. PLoS One 2023; 18:e0282185. [PMID: 36848347 PMCID: PMC9970109 DOI: 10.1371/journal.pone.0282185] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Accepted: 02/08/2023] [Indexed: 03/01/2023] Open
Abstract
This systematic review and meta-analysis aimed to examine more recent data to determine the extent of lingual nerve injury (LNI) following the surgical extraction of mandibular third molars (M3M). A systematic search of three databases [PubMed, Web of Science and OVID] was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The inclusion criteria encompassed studies on patients who underwent surgical M3M extraction using the buccal approach without lingual flap retraction (BA-), buccal approach with lingual flap retraction (BA+), and lingual split technique (LS). The outcome measures expressed in LNI count were converted to risk ratios (RR). Twenty-seven studies were included in the systematic review, nine were eligible for meta-analysis. Combined RR for LNI (BA+ versus BA-) was 4.80 [95% Confidence Interval:3.28-7.02; P<0.00001]. The prevalence of permanent LNI following BA-, BA+ and LS (mean%±SD%) was 0.18±0.38, 0.07±0.21, and 0.28±0.48 respectively. This study concluded that there was an increased risk of temporary LNI following M3M surgical extractions using BA+ and LS. There was insufficient evidence to determine whether there is a significant advantage of BA+ or LS in reducing permanent LNI risk. Operators should use lingual retraction with caution due to the increased temporary LNI risk.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2023; 124:101383. [PMID: 36646285 DOI: 10.1016/j.jormas.2023.101383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Accepted: 01/12/2023] [Indexed: 01/15/2023]
Abstract
OBJECTIVE To construct a novel portable tooth sectioning guide to improve the accuracy of mandibular third molar extraction. METHODS First, 72 samples of an identical 3D-printed double-rooted mandibular third molar were obtained and used in 36 mandibular models. Three different models were constructed (class B vertical, mesial, and horizontal impaction). Then, we made the tooth sectioning guides. mimicking clinical tooth sectioning conditions, two dental surgeons with different levels of experience used both the digital guided technique and the traditional empirical technique during surgery. Accuracy indicators, including apical deviation and angle deviation, were analyzed and compared on postoperative cone-beam computed tomographic scanning and via image reconstruction. Descriptive statistical analyses were performed. A p-value of 0.05 indicated statistically significant differences among the groups. RESULTS Overall, the mean apical deviation of experienced/inexperienced operators using the conventional section technique was 1.120 mm (0.7 mm, 2.3 mm) and 1.54± 0.84 mm, respectively. Correspondingly, the mean apical deviation under the guided section technique was 0.28 mm (0.2 mm, 0.4 mm) and 0.32±0.16 mm, respectively. The mean angle deviations of experienced/inexperienced operators under the conventional section technique were 8.015° (3.5°, 10.5°) and 6.570° (5.5°, 14.9°). Correspondingly, the mean apical deviation using the guided section technique was 1.880° (0.4°, 2.9°) and 1.470° (0.7°, 3.1°), respectively. The conventional and guided techniques were significantly different (P < 0.001). CONCLUSIONS In the digital guide technique, sectioning is more predictable and accurate, and the success of the operation is achievable with different proficiencies among dental surgeons. CLINICAL SIGNIFICANCE This technique will not only reduce the difficulty of tooth extraction but also reduce the risk of damage to the surrounding soft and hard tissues, especially damage to the inferior alveolar nerve.

Cureus 2023; 15:e34799. [PMID: 36923185 PMCID: PMC10008767 DOI: 10.7759/cureus.34799] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Accepted: 02/09/2023] [Indexed: 02/11/2023] Open
Abstract
Aim We aim to look at the differences between the standard Ward's incision and the comma-shaped incision and how they affect complications after surgery to remove an impacted mandibular third molar. Materials and methods Mandibular third molars had to be carefully extracted from a total of 40 patients who were randomly divided into two groups of 20 patients each. At first, patients were evaluated before surgery. In group A, a standard Ward's incision was made, and in group B, a comma incision was made to match the mucoperiosteal fold. Afterward, the impacted third molars were carefully removed. The evaluation criteria for pain, swelling, lockjaw, and healing of wounds were done before surgery, after three hours, and on the first, third, and seventh day after surgery. Result The pain scores that were recorded right after surgery, three hours later, and on days 1, 3, and 7 in the surgical area with comma-shaped incision were all lower than the pain scores that were recorded in the area where standard incisions were made. Enlarging was less with comma entry point than with standard Ward's incision. After surgery, there was a big difference between the two entry points in how the mouth opened and how the wounds were fixed. These findings showed that the comma incision is better than the standard Ward's incision when it comes to pain, enlargement, lockjaw, and healing of wounds. Conclusion The study results showed that the comma-shaped incision was better than the traditional method (Ward's incision) because there were fewer problems after surgery.

Abstract
Introduction: The aim of this study was to compare the reliability and the agreement of the Pederson and Pernambuco difficulty indexes in predicting the surgical extraction difficulty of the impacted mandibular third molars. Materials and methods: A prospective observational cohort study was conducted on 83 patients who had undergone surgical removal of impacted mandibular third molar. The difficulty of extraction was determined preoperatively according to the total scores obtained from the Pederson and Pernambuco difficulty indexes, the operative difficulty was determined by the surgical technique and the duration of extraction. The accuracy of prediction of the surgical difficulty and the degree of agreement of the two indexes were calculated. Results: The accuracy of Pederson and Pernambuco indexes in predicting the operative difficulty measured by duration of surgery was 36.1% and 55.4% respectively, and with operative difficulty measured by the technique was 21.7% and 37.3% respectively with statistically significant differences. The agreement between the 2 indexes was poor. Conclusion: Both indexes were limited in predicting the surgical difficulty of impacted mandibular third molars although the Pernambuco index was better than the Pederson index and the agreement between the two indexes was poor.

Abstract
BACKGROUND Assessing the time required for tooth extraction is the most important factor to consider before surgeries. The purpose of this study was to create a practical predictive model for assessing the time to extract the mandibular third molar tooth using deep learning. The accuracy of the model was evaluated by comparing the extraction time predicted by deep learning with the actual time required for extraction. METHODS A total of 724 panoramic X-ray images and clinical data were used for artificial intelligence (AI) prediction of extraction time. Clinical data such as age, sex, maximum mouth opening, body weight, height, the time from the start of incision to the start of suture, and surgeon's experience were recorded. Data augmentation and weight balancing were used to improve learning abilities of AI models. Extraction time predicted by the concatenated AI model was compared with the actual extraction time. RESULTS The final combined model (CNN + MLP) model achieved an R value of 0.8315, an R-squared value of 0.6839, a p-value of less than 0.0001, and a mean absolute error (MAE) of 2.95 min with the test dataset. CONCLUSIONS Our proposed model for predicting time to extract the mandibular third molar tooth performs well with a high accuracy in clinical practice.

Abstract
Background Procedures in oral surgery, especially surgical extraction of the impacted mandibular third molar is often considered anxiety-producing and stressful. This study evaluated the effect of oral sedation (5 mg diazepam) on the physiological stress level in subjects that underwent surgical extraction of the mandibular third molar by measuring the change in salivary cortisol concentration. Subjects and methods 204 salivary samples were collected from 102 subjects between 9.00 am and 12.00 pm to standardise the diurnal variations of cortisol secretion. Saliva samples were collected 45 min before and 15 min after surgical extraction from each subject in either group. The samples were stored in the freezer (- 20 °C) until analysis was done in the laboratory using salivary cortisol ELISA kits (DiaMetra S.r.l., Eagle Biosciences, Italy), and the cortisol concentration was measured with a microplate reader. Results There was a statistically significant change (p = <0.001 between the pre-surgical extraction salivary cortisol concentration of all subjects with a median of 7 ng/ml and post-surgical extraction salivary cortisol concentration of both the study and the control groups with a median of 17 ng/ml and 15 ng/ml, respectively. Only 11.8% of subjects in the study group had a reduction in post-surgical salivary cortisol concentration, while in the control group, 3.9% of subjects had a reduction in post-surgical salivary cortisol concentration. There was no statistically significant difference between the two groups (p = 0.135). Conclusions Hence, oral sedation has no significant impact on physiological stress during the surgical extraction of the mandibular third molar. However, salivary cortisol concentration can adequately reflect the stress induced by surgical extraction in subjects and its usefulness as a biomarker in stress research. Furthermore, the type of disimpaction of mandibular third molar affects salivary cortisol concentration, with distoangular disimpaction having the highest cortisol concentration and more stressful to subjects when compared to other types of disimpaction.

[PMID: 35448066 PMCID: PMC9031928 DOI: 10.3390/dj10040072] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 04/02/2022] [Accepted: 04/11/2022] [Indexed: 01/18/2023] Open
Abstract
(1) Background: Antibiotics are used in every medical field including dentistry, where they are used for the prevention of postoperative complications in routine clinical practice during the third molar extraction. (2) Methods: This study is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The present systematic review aimed to evaluate and systematize the use of antibacterial drugs in order to prevent postoperative complications in outpatient oral surgery for wisdom teeth extraction. We conducted a systematic review using electronic databases such as Medline PubMed, Scopus, and the Cochrane Central Register of Controlled Trials. Considering inclusion and exclusion criteria, we included randomized clinical trials published up to 2021 investigating the antibiotic prescription for third molar extraction. (3) Results: We selected 10 studies after the application of inclusion and exclusion criteria. The results showed that the most widely used antibiotic was amoxicillin both with and without clavulanic acid, in different dosages and duration. There were no statistically significant differences between treatment groups for development of postoperative complications. (4) Conclusions: Based on the analysis of the included studies, penicillin is currently the most widely prescribed group of antibiotics. The widespread use of this antibiotic group can lead to antimicrobial resistance (AMR). Due to increasing prevalence of bacteria resistance to penicillins, clinicians should carefully prescribe these antibiotics and be aware that the widespread use of amoxicillin may do more harm than good for the population.

Abstract
Background Dental treatment of anxious patients induces stress due to the patients' expectation of pain. This may prolong treatment due to such patients' inability to cooperate during treatment. Aim The aim of the study was to determine the effect of dental anxiety on surgical time of mandibular third molar (M3) disimpactions at a Nigerian hospital. Subjects and Methods A prospective study was conducted at the Oral Surgery clinic of Aminu Kano Teaching Hospital, Kano, between October 2016 and September 2017 to assess the effect of dental anxiety on surgical time of M3 disimpactions using the Modified Dental Anxiety Scale (MDAS). The Patients' biodata, clinical and M3 radiologic data were recorded. Surgical durations were also recorded. Data were analyzed with Statistical Package for Social Sciences for Windows (IBM statistics 23 software). Results One hundred and sixteen subjects (64 males, 52 females) were studied. Forty-two subjects (36.2%) were mildly anxious, 67 (57.8%) were moderately anxious, and 7 (6.0%) were highly anxious. The females were more anxious and the overall surgical time (OST) of disimpaction correlated with the anxiety levels of the subjects. The OST increased by approximately 0.8 min with every unit rise in the anxiety score. Other factors that affected OST in the study were M3 depth, type of impaction, and root curvature. Conclusion The patients' dental anxiety increased the surgical time of M3 disimpactions. Clinicians should consider the patients' anxiety among the factors that affect the surgical time of M3 disimpactions. Verbally soothing anxious patients and administering anxiolytic when necessary, may help to reduce the patients' anxiety, and hence, prevent surgical time prolongation.

Abstract
PURPOSE The present study aimed to evaluate which factors were statistically associated with a greater probability of inferior alveolar nerve (IAN) damage during lower third molar surgery. METHODS A prospective observational study was performed at the Oral Surgery Unit of the Umberto I Hospital on 92 patients who underwent surgical extraction of a lower third molar that was radiographically overlapped with the mandibular canal. All surgeries were performed by the same expert surgeon. A principal component analysis and the exact 2-tailed Fisher exact test were used. RESULTS Temporary IAN damage occurred in 10 cases (10.9%). Symptoms lasted from 18 to 180 days (73 ± 49.15). IAN damage was more frequent in difficult and long-lasting surgeries, in the presence of many risk factors and in patients with a reduced maximum mouth opening. CONCLUSION Such factors should be accurately evaluated before surgery to assess and discuss the overall surgical risk of IAN damage with the patient especially when they are over the maximum limit of their significant variability range found in the present study, that is, >12 for difficulty index, >2 for number of orthopantomography risk markers and <3.7 cm for maximum mouth opening.

Abstract
Objectives To assess the correlation of factors of WHARFE assessment and Pederson difficulty index for impacted mandibular third molar surgery. Study Design A comparative study of difficult factors utilizing Pederson WHARFE and WAR lines was performed involving patients undergoing surgical removal of mandibular third molars for 100 such teeth. Results The Spearman's rho correlation run to determine the relationship between Pederson difficulty index and WHARFE assessment values showed a strong, positive monotonic correlation at the 0.05 level (2-tailed; rs = 0.242, n = 100, p = 0.015 < 0.05). Conclusion The study has revealed WHARFE assessment to be a more reliable and consistent measure for the radiological evaluation of surgical difficulty over the contemporary Pederson difficulty index.

Abstract
Classifications of impacted teeth allow defining the type and degree of retention, as well as assessing the degree of difficulty of the procedure. The aim of this study was to conduct retrospective analysis of the degree of retention and difficulty in the surgical removal of impacted mandibular third molars in the clinical material of the Department of Oral Surgery in 2013–2018. This study included 1585 dental panoramic radiographs of patients of the Department of Oral Surgery, who reported in 2013–2018, in order to perform surgical removal of the impacted mandibular third molar. Based on dental panoramic radiographs, the degree of retention was determined based on classifications according to Winter, according to Pell and Gregory, according to Tetsch and Wagner, and according to Asanami and Kasazaki. The difficulty of the procedure was also assessed based on the Pederson index. The most common types of lower wisdom tooth impaction are as follows: in Winter’s classification, mesial-angular impaction; in Tetsch and Wagner’s classification, oblique medial-angular impaction; in Pell and Gregory’s classification, impaction grade 2A; and in Asanami and Kasazaki’s classification, 3A and anterior inclination. In most cases of surgical removal of an impacted tooth, the anticipated difficulty of the procedure was rated as very difficult.

Abstract
BACKGROUND A number of efforts have been made to establish a reliable assessment model for the surgical removal of impacted third molars. Although many such models have been proposed, none is considered universally applicable, and controversy remains. The earlier attempts were based exclusively on radiographic variables, whereas recent evidence is associated with nonradiographic and demographic variables. PURPOSE This article aimed to prepare review of the relevant literature to summarize the important indices given till date, tabulating only new indices as old indices are mentioned in almost all text books, their merits and demerits and their specificity and sensitivity (if assessed in the literature). In addition to it, authors also aimed to introduce a new descriptive classification of all indices based on pre- and postoperative assessment and further classify based on clinical, radiographic and demographic factors, surgical technique and time. This article will be of academic and practical help for residents and clinicians. METHOD A literature search was conducted in Medline, PubMed, Google Scholar, Science Direct and Cochrane electronic database with keywords-impacted mandibular third molar, difficulty indices, validity of, sensitivity, specificity. No publication year limit was used. The abstracts of the articles were retrieved, reviewed and sorted based on the following inclusion and exclusion criteria. Articles which include a new index, validate difficulty index, compare two or more difficulty indices, specificity and sensitivity of particular index are included. Duplicate articles, articles on complication, flap design, drug study, radiographic relation of inferior alveolar nerve, suturing, classification, only assessing factor affecting difficulty of third molar surgery are not included. RESULTS Total 39 (36 articles + 3 books) are included. A total of 20 individual indices were found in the literature; each has been described in brief in this review. These indices are also listed in chronological order with their specificity and sensitivity if accessed in the literature. CONCLUSION There is a definite need to derive and validate an user-friendly index that could be used for preoperative prediction of difficulty. To the best of our knowledge, this review including all indices till date and classification proposed is the first on this subject.

Abstract
OBJECTIVE This study examined the frequency of unplanned follow-up visits to the Public Dental Service in Örebro due to postoperative discomfort/complications after mandibular third molar surgery and associated factors. MATERIALS AND METHODS Data were retrieved from the dental records of 465 patients who underwent mandibular third molar surgery in 2017. The collected data covered patient age and gender, health status, diagnosis, surgeon, and planned and unplanned follow-up visits. RESULTS Twenty-eight percent of patients had unplanned visits after mandibular third molar surgery, while 68% of patients without a planned follow-up visit had an unscheduled visit. None of the patients with a planned visit had an unplanned visit. Female patients and patients who had bone removed during surgery had significantly more unplanned follow-up visits due to post-extraction discomfort (p=.047 and .01, respectively). Patients diagnosed with caries made fewer unplanned follow-up visits (p<.012). CONCLUSIONS The frequency of unplanned follow-up visits after third molar surgery was relatively high, though no patient with a planned follow-up visit made an unplanned visit. Scheduling follow-up visits could significantly reduce the number of unplanned follow-up visits.

Abstract
Black Lives Matter represents positive action towards equality and inclusivity. The Black Lives Matter protests remind us that, as a society, prejudices and unconscious bias still exist throughout the world. So, how does this inequality impact UK dentistry and what lessons can we learn?Black British dentists and dental care professionals (DCPs) are greatly under-represented in the UK workforce. The cause is multifactorial, but clearly measures need to be made from an early age, as Black prospective students have a 19% acceptance rate into dentistry, compared with 54% white and 41% Asian.As a Black British dental student working with my White British dental tutor, we address barriers that affect Black students and offer recommendations. These struggles are not exclusively related to skin colour, but evidence shows that Black British individuals are more likely to experience detrimental factors.We recognise that it is not the majority that suffer from under-representation, but the minorities; it filters into all aspects of dentistry, including treatment planning and disease diagnosis. Black DCPs and dentists have a contextual understanding of the barriers their communities face and will prove pivotal in workforce diversification. However, we all have a part to play in improving healthcare quality. Together, we can do more.

Abstract
This paper proposes a convolutional neural network (CNN)-based deep learning model for predicting the difficulty of extracting a mandibular third molar using a panoramic radiographic image. The applied dataset includes a total of 1053 mandibular third molars from 600 preoperative panoramic radiographic images. The extraction difficulty was evaluated based on the consensus of three human observers using the Pederson difficulty score (PDS). The classification model used a ResNet-34 pretrained on the ImageNet dataset. The correlation between the PDS values determined by the proposed model and those measured by the experts was calculated. The prediction accuracies for C1 (depth), C2 (ramal relationship), and C3 (angulation) were 78.91%, 82.03%, and 90.23%, respectively. The results confirm that the proposed CNN-based deep learning model could be used to predict the difficulty of extracting a mandibular third molar using a panoramic radiographic image.

Abstract
PURPOSE The purpose of this study was to introduce the method and first results of a modified tooth sectioning technique for the extraction of horizontally impacted mandibular third molars (M3Ms) with large root bifurcation. PATIENTS AND METHODS A total of 300 horizontally impacted M3Ms with large root bifurcation in medically healthy patients were included in this prospective study. Patients were divided into 2 groups: the modified method group (test group), in which the M3M was sectioned between the distal root and the remainder of the tooth at the point of root bifurcation; and the conventional method group (control group), in which the M3M was sectioned between the crown and the root at the cementoenamel junction. Operation duration, postoperative reactions, complications, and patient satisfaction were analyzed and compared between the 2 groups. RESULTS Each group included 150 M3Ms which were all successfully extracted. Operation durations in the test and control group were 10.48 ± 3.78 and 15.09 ± 4.24 minutes, respectively (P < .05). The test group had significantly better results than the control group with regard to postoperative reactions and complications (P < .05). Patients in the test group had higher satisfaction ratings regarding operation duration and the healing process than those in the control group (P < .05). CONCLUSIONS The modified method of tooth sectioning between the distal root and the remainder of the tooth can efficiently eliminate resistance from the bone and adjacent mandibular second molar and allow for just 1 sectioning of the M3M in most cases, which could make the operation straightforward and safe.

Abstract
The aim of this study was to evaluate patient perception of surgical discomfort in third molar surgery and the association with clinical variables and polymorphisms associated with the FKBP5, SLC6A4, and COMT genes. This cross-sectional observational study was carried out on 196 participants aged between 18 and 64 years at the Federal University of Paraná in 11 months. The intensity of surgical discomfort was assessed using the QCirDental questionnaire. Data on surgical and individual procedures were also cataloged. The oral health related quality of life was assessed by the Oral Health Impact Profile questionnaire (OHIP-14). The DNA sample was obtained from cells of the oral mucosa. Five markers of the FKBP5, SLC6A4, and COMT genes were genotyped. The data were submitted to statistical analysis with a significance level of 5%. Women reported greater intensity of discomfort associated with third molar surgery compared to men (p = 0.001). In the recessive model, the AA genotype of the rs3800373 marker was associated with greater surgical discomfort (p = 0.026). Therefore, women and individuals of the AA genotype for the rs3800373 marker in the FKBP5 gene reported greater surgical discomfort associated with third molar surgery.

[PMID: 32994868 PMCID: PMC7511046 DOI: 10.4317/jced.56549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2019] [Accepted: 05/14/2020] [Indexed: 11/26/2022] Open
Abstract
Background Third molars are present in 96.6% of humans, although they do not always erupt completely. Between 9.5% and 73% of them remain impacted. Surgical removal of impacted third molars is the most common practice in oral and maxillofacial surgery. This procedure results in traumatism and, consequently, the postoperative phase will involve symptomatology. It is uncommon to find studies that directly relate postoperative symptomatology and the operator’s experience. The aim of this study was to determine the differences regarding postoperative symp-tomatology in patients undergoing the bilateral extraction of lower impacted third molars and according to the operator’s experience.
Material and Methods A prospective cohort double-blind study was conducted in 50 healthy patients (100 molar extractions) to whom both lower third molars were removed by two dentists with different degree of professional experience. The extractions were randomly assigned with a split–mouth design. If an operator extracted the lower third molar on one side, the other operator extracted the contralateral one. The variables studied after four days of postoperative period were Pain (EVA scale), Inflammation and Trismus, in addition to intraoperative time and local anesthesia administered.
Results Statistically significant differences were detected in the time of intervention and in trismus, since the most experienced operator always needed less time and caused higher degree of trismus. However, this does not entail more inflammation or pain in patients, so there are no relevant differences between operators with more or less experience (p>0.05).
Conclusions The postoperative period is more favorable for the most experienced operator, although the results do not vary in a relevant manner between them. Key words:Preemptive analgesia, dental extraction, cyclooxygenases, real-time polymerase chain reaction.

Abstract
Background Surgical removal of the impacted third molar is associated with inflammatory morbidities which include swelling, trismus, and pain. Pain is the most common postsurgical morbidity associated with third molar surgery. It remains an important factor in patients' perception of recovery after third molar surgery with dental anxiety reported to exert influence on its threshold. Objective The aim of the study was to determine if preoperative dental anxiety has any significant role on postoperative pain perception after third molar surgery. Materials and Methods This was a cohort study involving sixty consecutive adult patients requiring extraction of impacted mandibular third molars under local anesthesia. Modified Dental Anxiety Scale Questionnaire was administered to each participant in the waiting area before the surgery. The visual analog scale was also given to each participant to be completed once daily at approximately the same time as the surgery time until day 7 after the surgery. Data collected were analyzed using SPSS version 23. Results Sixty participants who consented to third molar surgery took part in this study. Five participants were lost to follow-up. There were slightly more males (50.9%) than females (49.1%). Nineteen participants in this study had moderate dental anxiety (34.5%) and 6 participants (11%) had severe dental anxiety with more females having moderate-to-severe dental anxiety. The correlation between pain perception at different days and dental anxiety was not significant (P > 0.05). Conclusion Preoperative dental anxiety may not significantly influence pain perception after third molar surgery.

Abstract
The microflora of the distal pocket is considered as the major cause of pericoronitis. How the oral microflora changes during pericoronitis and whether different types of impacted third molar harbor the same microflora are still unknown. Saliva, subgingival plaque, and gingival plaque of mandibular third molars (M3Ms) were collected from twelve patients with acute pericoronitis. They were given local irrigation or local irrigation + antibiotics according to symptoms. Samples were harvested at the first visit with pericoronitis, 1 week after treatment, and 6 weeks after treatment. 16S rRNA gene polymerase chain reaction products were generated and sequenced after DNA isolation. Comparison of three sampling sites showed that, the subgingival plaque of M3Ms had most remarkable changes in symptomatic period, including a significant increase in microbial richness, and a convergent trend in microbial composition. After treatment, the subgingival microbiome was altered and largely returned to the state in asymptomatic period. In summary, the distal subgingival microbiota of M3M was most likely to be associated with the pathogenesis of pericoronitis. The post-treatment microbiota shift of M3M proved the effectiveness of treatment. The inclination type of impacted M3Ms and treatment method would also make a difference to the pericoronal microbiota.

Correlation Between Height and Impacted Third Molars and Genetics Role in Third Molar Impaction. J Maxillofac Oral Surg 2020; 20:149-153.

Abstract
Aim This study sought to evaluate the relationship between height of an individual and the presence of impaction of maxillary and mandibular third molars, and to determine the role of genetics in third molar impaction. Materials and Methods This was a case-control study, with cases consisted of 200 subjects with third molar impactions; and 200 controls without third molar impactions. Height of subjects was measured, and saliva samples were collected from all the subjects. DNA was extracted from saliva samples. To investigate the role of selected genes in the etiology of third molar impactions, Taqman Genotyping using SNPs identified for jaw growth, height and tooth agenesis was employed. Five candidate genes were investigated using 11 markers (SNPs). Results The mean height of cases was significantly lower than that of the control subjects (p = 0.04). No difference was found in allele frequency between cases and controls for 10 of the 11 SNPs. However, for rs6504591 the p value was near significance (p = 0.07) with odd ratio of 2.131. Subjects with lower third molar impactions were significantly shorter than those who have fully erupted third molars. Conclusions Subjects with lower third molar impactions were significantly shorter than those who have fully erupted third molars. We observed that individuals with third molar impaction tend to have T allele at the locus, suggesting that the T allele at the locus may increase the risk for having an impacted third molar. The rs6504591 G/T variation on human chromosome 17 (WNT9B gene) appears to increase risk by twofolds for impaction albeit with inability to detect significance due to small sample size.

Abstract
Background In dentistry, pain is a factor that negatively affects treatments and drug use. The aim of this study was to evaluate the correlations of the postoperative analgesic use with pain catastrophizing and anxiety in patients who underwent removal of an impacted mandibular third molar. Methods We recruited 92 patients who underwent the extraction of impacted mandibular third molar. In this study, the Pederson index was used to preoperatively determine the difficulty of surgical extraction. Patients were asked to note the number of analgesics used for 7 postoperative days. Patients were divided into two groups based on the Pain Catastrophizing Scale: low and high score groups. State-Trait Anxiety Inventory-trait and State-Trait Anxiety Inventory-state questionnaires were used to determine the anxiety levels of the patients. The obtained data were examined to evaluate the correlations of pain catastrophizing and anxiety with the postoperative analgesic use. Results In this study, 92 patients, including 60 women and 32 men, were recruited. The analgesic use was higher in women than in men but with no significant difference (P > 0.05). Pain Catastrophizing Scale scores were higher in women than in men but with no significant difference (P > 0.05). The analgesic use was higher in patients with high pain catastrophizing than in those with low pain catastrophizing but with no significant difference (P > 0.05). State-Trait Anxiety Inventory-trait scores were higher in women than in men but with no significant difference. However, state-Trait Anxiety Inventory-state scores were significantly higher in women than in men (P < 0.05). Conclusion The postoperative analgesic use may be higher in patients who catastrophize pain than in others. Knowing the patient's catastrophic characteristics preoperatively would contribute to successful pain management and appropriate drug selection.

Abstract
The aim of this systematic review was to determine the patient, radiological, and operative variables associated with surgical difficulty in the extraction of third molars, according to a visual analogue scale completed by the surgeon, operative time, or surgical technique. Searches of the PubMed (MEDLINE), Scopus, and Cochrane Library databases were conducted by two independent reviewers. Randomized and non-randomized clinical trials and prospective cohort studies evaluating surgical difficulty in the extraction of impacted mandibular or maxillary third molars according to patient, radiological, and operative variables were included. The full texts of 21 of the 859 articles initially retrieved were analysed, and 15 articles were included in the final systematic review. All 15 reported prospective cohort studies. The following variables were found to be on the spectrum of highly difficult or complex cases: older patient age and being overweight (patient variables), surgeons with little experience and the use of complex surgical techniques requiring tooth sectioning linked to hard tissue impaction (operative variables), and adverse radiological factors such as deep impaction, unfavourable angulation and root morphology, and a close relationship with the second molar, maxillary sinus, or the inferior alveolar nerve canal (radiological variables).

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2019; 121:107-112. [PMID: 31526906 DOI: 10.1016/j.jormas.2019.09.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2019] [Revised: 08/13/2019] [Accepted: 09/10/2019] [Indexed: 11/19/2022]
Abstract
INTRODUCTION Primarily, the intensity of local anesthesia (LA) in mandibular third-molar (M3) surgery is governed directly by lipid solubility of the local anesthetic drug and indirectly by other physical characteristics. However, a patient's demographic, anthropometric, behavioral, and surgical factors may affect these physical characteristics and, therefore, indirectly influence the clinical actions of the local anesthetic drug used. The aim of this study was to investigate patients' demographic, anthropometric, behavioral, and surgical variables that may predict for the intensity of LA in mandibular M3 surgery among healthy adult patients. MATERIAL AND METHODS This cross-sectional study included 141 patients with unilateral mandibular M3 teeth indicated for surgical extraction under LA. Patients' demographic, anthropometric, behavioral, and surgical potential predictor variables were recorded. Lidocaine (2%) with epinephrine (1:100,000) was administered to provide block anesthesia for mandibular M3 surgery. The overall intra-operative pain (intensity of LA) was the outcome variable and was evaluated by the patient after surgery, using a visual analogue scale (VAS). Data were analyzed using univariate analysis and multivariate regression analysis. RESULTS The final study population comprised 126 participants: 80 women and 46 men (mean age±SD=29.2±12.3 year). With multivariate regression analysis, age, smoking quantity, and "amount of local anesthetic used" were the only significant (P<0.001) predictors of the intensity of LA in mandibular M3 surgery. CONCLUSIONS This study suggested that an increase in age, smoking quantity and "amount of local anesthetic used" would predict an increase in the intensity of LA in mandibular M3 surgery.

Abstract
PURPOSE The present study investigated the relationship of impacted mandibular third molars to the cortical plates and inferior alveolar canal (IAC) using cone-beam computed tomography (CBCT). MATERIALS AND METHODS The present study included CBCT images of 386 lower third molars in 226 patients, for whom the initial panoramic radiographs had revealed a close relationship between the third molars and IAC. The coronal images were prepared to determine the position of apex about the buccal and lingual cortexes and IAC. The impacted third molars were categorized using the Winter and the Pell and Gregory classifications. The relationship between the third molars and buccal/lingual cortexes and IAC was determined in the different classes of the Winter and the Pell and Gregory systems. RESULTS The mesioangular position was more prevalent in the present sample. Most teeth were Class I concerning the ascending ramus and level C in depth. Generally, the impacted mandibular third molars showed a lingual position and were in contact or intersecting into the IAC. A significant association was found between the type of tooth impaction using the Winter and the Pell and Gregory classifications and the position of the third molar teeth concerning the cortical plates and IAC. CONCLUSIONS The possibility of the buccal position of the tooth and the chance of an intersection of the apex into the IAC was greater in teeth that were mesioangular and were Class III concerning the ascending ramus and level C in depth. These data should be considered during the preoperative assessment of third molars to reduce postoperative complications.

Abstract
PURPOSE This study aimed to develop a straightforward and accurate index of impacted third molar removal difficulty through analyzing various factors to assess the difficulty level of impacted mandibular third molar (IMTM) extraction. MATERIALS AND METHODS This prospective cohort study included 203 patients who required IMTM extraction. All patients were selected using the preset selection criteria. The present study assessed operation difficulty with operating time. A mathematical model and regression analysis were performed to explore 6 main factors (age, number of roots, degree of bone impaction, shape of roots, and impaction angle and its relation). Appropriate correction coefficients were obtained to formulate a new IMTM removal difficulty predictive index. Consistency of the κ value was checked to evaluate performance. RESULTS Degree of bone impaction had the highest correlation coefficient (0.576), followed by shape of roots (0.359), and the lowest correlation coefficient was for number of roots. The Pederson index for these 203 patients showed that 75, 76, and 52 patients had low, moderate, and high difficulty levels, respectively, whereas the new index categorized 78, 85, and 40 patients as having low, moderate, and high difficulty. Comparison of the Pederson index and new index with operating time showed κ agreements of 65.30 and 77.9% (P < .01), suggesting that the prediction results of the new index are more objective and accurate. CONCLUSION The newly proposed index is straightforward and efficient and exhibited promising results in κ agreement. Because of its straightforward nature, it is better suited for Chinese public hospitals with a large volume of patients who require alveolar surgery. The detection of predictor variables could be useful for graduate students, professionals, and general dental practitioners contemplating IMTM removal to assess the difficulty level of IMTM extraction.

Relationship Between Surgical Difficulty of Third Molar Extraction Under Local Anesthesia and the Postoperative Evolution of Clinical and Blood Parameters. J Oral Maxillofac Surg 2019; 77:1337-1345. [PMID: 30878593 DOI: 10.1016/j.joms.2019.02.020] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Revised: 02/12/2019] [Accepted: 02/12/2019] [Indexed: 12/01/2022]
Abstract
PURPOSE To determine whether the Pederson scale is a good predictor of the surgical difficulty of third molar extraction and establish whether such surgical difficulty is directly related to the postoperative course as assessed from clinical (pain, inflammation, and trismus) and blood (C-reactive protein, interleukin-6 [IL-6], and fibrinogen) parameters. MATERIALS AND METHODS A prospective observational study was conducted of 2 groups of patients who underwent simple or surgical third molar extraction under local anesthesia. Clinical and blood parameters and possible complications were recorded for 1 week after extraction. RESULTS A total of 118 patients were studied. Surgical difficulty as predicted by the Pederson scale showed significant differences (P < .001) for osteotomy, sectioning of the crown, root sectioning, duration of intervention, type of closure, and number of sutures. Under conditions of equal surgical difficulty, the evolution of the groups was similar for pain and inflammation, although trismus was greater for patients subjected to surgical extraction. After the operation, marked increments were recorded in serum C-reactive protein, IL-6, and fibrinogen, although without differences among different levels of surgical difficulty. The probability of complications was similar in the routine and surgical extraction groups. The appearance of complications was the principal cause of alterations in clinical and blood parameters. CONCLUSIONS The Pederson scale is a good predictor of the surgical difficulty of third molar removal as assessed from different clinical and blood parameters. C-reactive protein, IL-6, and fibrinogen concentrations varied considerably after the operation but were not influenced by the degree of surgical difficulty. The presence of postoperative complications was associated with a poorer evolution of clinical and blood parameters.

Abstract
Introduction Oral surgery services are progressively moving out of traditional hospital departments and into primary care. This necessitates accurate methods of triaging referrals, so patients of varying complexity are managed in the most suitable environment. The latest NHS commissioning proposal identifies 'level 1' procedures as simple extractions which do not require referral. We developed a model for quantifying how accurately these simple extractions can be predicted from information in standard referral letters. Methods Experienced clinicians (N = 10) were independently asked to predict whether extractions (N = 25) were likely to be simple-forceps or surgical procedures, from information provided in specially developed standardised referral letters. One oral surgeon had previously completed all extractions. The triaging clinicians were asked to comment on reasons for each decision and state their level of confidence in their predictions. Results Only 67% (range 52–76%) of extractions were correctly predicted as either simple or surgical with a significant propensity to underestimate the complexity of surgical extractions rather than overestimating simple procedures (p <0.05). High levels of confidence reported by the clinicians in their decisions correlated with more accurate predictions (p <0.05). Conclusions This is the first attempt to develop a model for clinical decision-making in oral surgery triage services. Our findings suggest there is significant scope for improvement and highlight areas for development.

Alkadi S, Stassen L. Effect of One-Suture and Sutureless Techniques on Postoperative Healing After Third Molar Surgery. J Oral Maxillofac Surg 2019; 77:703.e1-703.e16. [PMID: 30611694 DOI: 10.1016/j.joms.2018.12.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2018] [Revised: 10/26/2018] [Accepted: 12/01/2018] [Indexed: 10/27/2022]
Abstract
PURPOSE The wound closure technique for lower third molar surgery (LTMS) is an operative factor that influences wound healing and the occurrence of early postoperative complications. The present study investigated 2 closure techniques (partial closure using 1 suture and the suture-less technique) after use of a modified buccal envelope flap for LTMS. MATERIALS AND METHODS We performed a prospective, randomized, double-blind, split-mouth, controlled trial. Partial closure using 1 suture was compared with closure using the sutureless technique. The surgical sites were divided into 2 groups, group A (1 suture) and group B (sutureless). Each patient received both treatments at the same surgery. During the first postoperative week, all patients were asked to daily assess pain, facial swelling, and bleeding using self-assessment scales. All patients attended the follow-up appointment at 1 week to objectively assess facial swelling and wound healing and at 1 month to assess wound healing. An analysis of data was performed using the statistical package SPSS Statistics, version 24 (IBM Corp, Armonk, NY). A P value ≤ .05 was accepted as statistically significant. RESULTS A total of 37 patients with bilateral impacted third molars of similar surgical difficulty were recruited. Of the 37 patients, 34 successfully completed the study. The results showed a statistically significant difference between the 2 techniques in postoperative pain at days 5 (P = .046) and 6 (P = .034); socket healing at 1 week (P = .002) and 1 month (P = .014), and soft tissue healing at 1 week (P = .016). CONCLUSION We found the 1-suture technique for LTMS to be superior to the sutureless technique in the reduction of postoperative pain and improving wound healing during the early postoperative period. We found no difference between the 2 techniques in the reduction of postoperative swelling.

Abstract
AIM: To evaluate a new technique for surgical removal of deeply impacted mandibular third molars (DIMTM), using computer-guided cutting guide to maintain inferior alveolar nerve (IAN) integrity and the covering buccal bone. PATIENTS AND METHODS: Eighteen cases indicated for removal of DIMTM. Cone-beam Computed Tomography (CBCTs) used to determine the tooth’s relation to the IAN. Computer-guided software used for fabrication of surgical cutting guide stent to expose the impacted tooth and repositioning of bone after odontectomy without fixation. Clinical assessment included a neurosensory deficit of IAN, pain using a visual analogue scale (VAS), facial swelling, and maximal mouth opening (MMO). CBCTs were taken immediately and six months postoperatively to evaluate position and healing of bone. RESULTS: None of the patients showed a permanent neurological deficit of IAN while all patients showed normal parameters of pain, facial swelling and MMO. CONCLUSION: this technique has shown the accurate determination of the bony window cuts with subsequent preservation of IAN and external oblique ridge.

Abstract
Aim The study intended to compare the analgesic effect and patient satisfaction of intranasal butorphanol with oral diclofenac sodium after surgical removal of impacted mandibular third molars. Materials and Methods This split-mouth prospective controlled clinical study included 50 patients with bilateral symmetrically impacted mandibular third molars with the same difficulty on the Pederson Index. All patients had two appointments of surgery. In the first, the molar on one side was surgically removed and depending upon the chit selected by the patient, either intranasal butorphanol or oral diclofenac sodium was prescribed postoperatively for pain relief. Two weeks later, the impacted mandibular third molar on the other side was surgically removed and if butorphanol was selected for the first side, then oral diclofenac sodium was prescribed for the other side and vice versa. Pain relief was recorded on the Facial Visual Analogue Scale at 1, 2, 3, 4 and 5 h postoperatively and on postoperative day 1 and 2 at the same time for both the drugs. Results Intensity of pain was less with intranasal butorphanol as compared to oral diclofenac sodium at all the time intervals and especially in the 1st postoperative hour. Overall acceptance (88%) to butorphanol nasal formulation was statistically similar to diclofenac sodium tablets. Conclusion Intranasal butorphanol at the very acceptable 1 mg dose after the surgical removal of impacted mandibular third molars provides a profound degree of analgesia. It is a well-tolerated drug with a high acceptance rate if administered correctly.

Abstract
The aim of this study was to assess the influence of patients' and surgical variables on the onset and duration of action of local anesthesia (LA) in mandibular third-molar (M3) surgery. Patients scheduled for mandibular M3 surgery were considered for inclusion in this prospective cohort study. Patients' and surgical variables were recorded. Two per cent (2%) lidocaine with 1:100,000 epinephrine was used to block the nerves for extraction of mandibular M3. Then, the onset of action and duration of LA were monitored. Univariate analysis and multivariate regression analysis were used to analyze the data. The final cohort included 88 subjects (32 men and 56 women; mean age ± SD = 29.3 ± 12.3 yr). With univariate analysis, age, gender, body mass index (BMI), smoking quantity and duration, operation time, and 'volume of local anesthetic needed' significantly influenced the onset of action and duration of LA. Multivariate regression revealed that age and smoking quantity were the only statistically significant predictors of the onset of action of LA, whereas age, smoking quantity, and 'volume of local anesthetic needed' were the only statistically significant predictors of duration of LA. Further studies are recommended to uncover other predictors of the onset of action and duration of LA.

Abstract
Background and Aim: One of the most commonly performed surgical procedures by oral and maxillofacial surgeons all over the world is the removal of impacted teeth. The most critical and important steps in third molar extraction are bone cutting or osteotomy. Many techniques are used for this purpose including chisels and mallet, rotary instruments, and ultrasonic-based bone cutting instruments. Piezotome is newer and innovative device for osteotomy based on piezoelectric vibrations. Piezotome is considered very efficient in performing osteotomy because of its selective cutting; being inert against soft tissues, including nerves and blood vessels. The aim of this study was to compare the surgical outcome of third molar surgery using conventional handpiece and piezotome with all other criteria remaining same for all the individuals. Materials and Methods: All patients reporting to the Department of Oral and Maxillofacial surgery, Manipal College of Dental Sciences, Mangalore, for impacted mandibular third molar removal were screened. A total of 30 patients with same Pederson difficulty index for bilateral impacted third molar were selected for the study. The study involved the use of piezotome on one side (Side A) and rotary technique (Side B) on the other side for osteotomy on the same patient with an interval of 1 month. Therapeutic management was same for both the sides. Operating time was recorded in each surgery. Patients were examined postoperatively on 1st, 3rd, and 7th day and pain, edema, trismus, paresthesia, and dry socket were evaluated and compared on both the sides. Data collected were analyzed statistically. Results: The mean operating time was 48.13 min in piezotome (Side A) and 32.90 min in conventional handpiece (Side B) which was statistically significant (P < 0.001). Furthermore, there was statistically significant difference (P < 0.001) in the level of pain (P < 0.001), number of analgesics taken (P < 0.001), and trismus (P < 0.01) on 1st, 3rd, and 7th days postoperatively. There was no statistically significant difference in edema between the two sides. Paresthesia was present in one patient (3.3%) in Side B, while no paresthesia was present in Side A. No incidence of alveolar osteitis was reported on both the sides. Conclusion: Operating time with piezotome was more than that of conventional handpiece, but the postoperative responses such as pain, trismus, and edema were less in piezotome. Hence, despite being a slower procedure, piezotome can be an effective alternative for osteotomy in impacted third molar surgery. We recommend using piezotome for bone cutting and conventional rotary handpiece for tooth sectioning in order to obtain favorable outcomes as well as decreasing the operating time.

Abstract
BACKGROUND AND OBJECTIVES Surgical removal of a mandibular impacted third molar is one among the most common oral surgical procedures. The objective of this study was to assess and identify risk indicators influencing extended operation time in relation to the surgical removal of mesioangular impacted mandibular third molar, position A, Class I and to evaluate the incidence of postoperative swelling, trismus, and pain. MATERIALS AND METHODS A prospective cohort was implemented and the patients who presented for mandibular third molar removal which were impacted in position A, Class I were enlisted for the study. During 1 year between July 2014 and June 2015, a total of 40 patients were enrolled in the study. The evaluation of patient variables and radiographic variables was done preoperatively. Depending on the duration of time taken for an operation, patients were divided into three groups: Group I, Group II, and Group III. Postoperative complications such as swelling, trismus, and pain were assessed in each of the patients. STATISTICAL ANALYSIS The statistical analysis was done among the groups using Chi-square test, and ANOVA. RESULTS Among the six variables studied in this study including patient variables and radiographic variables, maximum interincisal opening, external oblique ridge, and root morphology were found to be dependent factors which influence the operating time. Moreover, other variables such as the crown root width ratio and the number of roots were independent factors. Swelling, trismus, and pain were statistically significant among groups and were directly related to operating time. CONCLUSION We consider that the outcome of surgical removal of mandibular impacted third molar, position A, Class I depends significantly on relevant patients characteristics and radiographic variables which should be evaluated preoperatively as they are predetermined factors to avoid postoperative morbidity.

Abstract
Two different anesthesia models were compared in terms of surgical duration, safer outcomes, and economic implications. Third molar surgeries performed with and without a separate dentist anesthesiologist were evaluated by a retrospective data analysis of the surgical operative times. For more difficult surgeries, substantially shorter operative times were observed with the dentist anesthesiologist model, leading to a more favorable surgical outcome. An example calculation is presented to demonstrate economic advantages of scheduling the participation of a dentist anesthesiologist for more difficult surgeries.

Abstract
Background Several publications have measured the difficulty of third molar removal, trying to establish the main risk factors, however several important preoperative and intraoperative variables are overlooked. Material and Methods A prospective cohort study comprising a total of 130 consecutive lower third molar extractions was performed. The outcome variables used to measure the difficulty of the extraction were operation time and a 100mm visual analogue scale filled by the surgeon at the end of the surgical procedure. The predictors were divided into 4 different groups (demographic, anatomic, radiographic and operative variables). A descriptive, bivariate and multivariate analysis of the data was performed. Results Patients’ weight, the presence of bulbous roots, the need to perform crown and root sectioning of the lower third molar and Pell and Gregory 123 classification significantly influenced both outcome variables (p< 0.05). Conclusions Certain anatomical, radiological and operative variables appear to be important factors in the assessment of surgical difficulty in the extraction of lower third molars. Key words:Third molar, surgical extraction, surgical difficulty.

Abstract
INTRODUCTION The removal of impacted teeth is one of the most common procedures performed by oral and maxillofacial surgeons. Reduction of discomfort post-operatively and efficient local anesthesia are imperative for success in surgical practice. At sub-anesthetic doses, ketamine has a noticeable analgesic action, which can be used to supplement local anesthesia with minimal side effects. AIM To assess the efficacy of low-dose ketamine as an adjunct to local anesthesia in the management of pain, swelling and trismus after surgical removal of impacted mandibular third molars. MATERIALS AND METHODS Twenty five patients with bilaterally symmetrical impacted mandibular third molars requiring surgical removal under local anesthesia were selected for the controlled clinical study. The third molar sites of all patients enrolled in the trial were randomly assigned into 2 groups: Local Anesthesia (Lignocaine) Alone [LAA] and Local Anesthesia plus ketamine [LAK]. 5ml of local anesthetic (Lignocaine Hydrochloride 2% with epinephrine 1:100,000) was injected in the 'LAA' group while the 'LAK' group received 5ml of local anesthetic plus 0.2mg/kg ketamine. Patients were blinded to the solution used and the operator recorded the group (LAA or LAK) and the respective site (Right or Left) for analysis. Bilaterally symmetrical impacted mandibular molars were removed at an interval of 15 days. RESULTS Facial swelling on post-operative days was significantly lower in the LAK group than in the LAA group (p<0.05). The pain scores on the VAS were significantly higher in the LAA group than in the LAK group (p<0.05). CONCLUSION The role of ketamine in low doses as an analgesic and anti-inflammatory is evident in our study. The combination of a local anesthetic and sub-anesthetic doses of ketamine injected for surgical removal of impacted third molars provides good local anesthesia while alleviating post-operative sequelae for the patient by providing a degree of post-operative analgesia with less swelling.

Abstract
BACKGROUND The choice of the anaesthetic modality is one of the primary steps during planning of third molar surgery. The aim of the present study was to compare the risk of developing neurological injures of the inferior alveolar nerve (IAN) and lingual nerve (LN) in patients treated for wisdom teeth removal under general anaesthesia (GA) with a group treated under local anaesthesia (LA). MATERIAL AND METHODS This is an observational retrospective, unicentric study; between September 2013 and September 2014, 534 patients underwent third molar surgery, 194 (36,3%) under GA and 340 (63,7%) under LA by the same oral surgeon. Difference in the incidence of IAN and LN injures between groups have been statistically analyzed with Fisher exact test and estimated odd ratio for development of such complications has been calculated. RESULTS In GA patients the incidence of IAN and LN injures was 4.6% and 2.1%, respectively while in the LA group it was and 0.3% and 0%, respectively. A significant difference in IAN and LN involvement between groups was observed (IAN lesion: Fisher exact test, p<0.001; LN lesions: Fisher exact test, p<0.05). The estimated odd ratio for development of IAN injures after GA was 16.49 (95% CI: 2.07-131.19) and was not calculable for LN injures because no cases were observed in the LA group. CONCLUSIONS Since GA is a perioperative variable that seems to significantly increase the risk of developing IAN and LN lesions, when treating patients that request GA, they must be adequately informed that an higher incidence of post-surgical sensory disturbances is expected.

Abstract
BACKGROUND The purpose of this study was to identify potential concealed variables associated with the difficulty of lower third molar (M3) extractions. MATERIAL AND METHODS To address the research purpose, we implemented a prospective study and enrolled a sample of subjects presenting for M3 removal. Predictor variables were categorized into Group-I and Group-II, based on predetermined criteria. The primary outcome variable was the difficulty of extraction, measured as extraction time. Appropriate univariate and multivariate statistics were computed using ordinal logistic regression. RESULTS The sample comprised of 1235 subjects with a mean age of 29.49 +/- 8.92 years in Group-I and 26.20 +/- 11.55 years in Group-II subjects. The mean operating time per M3 extraction was 21.24 +/- 12.80 and 20.24 +/- 12.50 minutes for Group-I and Group-II subjects respectively. Three linear parameters including B-M2 height (distance between imaginary point B on the inferior border of mandibular body, and M2), lingual cortical thickness, bone density and one angular parameter including Rc-Cs angle (angle between ramus curvature and curve of spee), in addition to patient's age, profile type, facial type, cant of occlusal plane, and decreased overbite, were found to be statistically associated ( p < or = 0.05) with extraction difficulty under regression models. CONCLUSIONS In conclusion, our study indicates that the difficulty of lower M3 extractions is possibly governed by morphological and biomechanical factors with substantial influence of myofunctional factors. PRACTICAL IMPLICATIONS Preoperative evaluation of dynamic concealed factors may not only help in envisaging the difficulty and planning of surgical approach but might also help in better time management in clinical practice.

Abstract
Objectives The aim of this retrospective study was to investigate factors associated with increased difficulty in the surgical extraction of impacted lower third molars and to improve identification of difficult cases. Materials and Methods A total of 680 patients who required 762 surgical extractions of impacted lower third molars from 2009 to 2014 were enrolled in the study. Demographic factors, clinical factors, radiographic factors, surgical extraction difficulty, and presumed causes of difficulty were collected. Data were statistically analyzed using IBM SPSS Statistics version 23. Results Age, sex, depth of impaction, and blurred radiographic image influenced difficulty in surgical extraction. The position of the impacted tooth influenced surgical difficulty, especially when it was accompanied by other factors. Conclusion It is challenging to design a reliable and practical instrument to predict difficulty in surgical extraction of impacted lower third molars. To identify very difficult cases, root investigation using computed tomography is advised when impacted tooth position suggests difficult extraction.

Oral Maxillofac Surg 2016; 20:391-396.

Abstract
PURPOSE Iatrogenic fracture of mandible (IFM) associated with exodontia though rare, they do occur with an incidence ranging from 0.0034 to 0.0075 %. Most of the data is in the form of case reports or a small case series. This is an attempt to amass the data available in literature since the last 62 years. The purpose of this meta-analysis is to identify the etiologies and risk factors leading to IFM associated with exodontia and also the measures to minimize the complication. METHODS Articles published between 1953 and 2015 were searched in Medline database. Data was collected and analyzed based on age, gender, extracted tooth, status of dentition, pathological bone lesion adjacent to the tooth, type of impaction, angulation of the impacted third molar, site of fracture, side of fracture, time of fracture, and treatment of fracture. RESULTS A review identified 200 documented cases of IFM associated with the removal of teeth. The reasons for its occurrence found to be multifactorial with a higher incidence in the fifth decade of life with male prevalence. Risk factors more commonly identified were removal of the third molar, fully dentate patient, associated pathology, impacted tooth, angle region, left quadrant, and time interval of 3 weeks postoperatively. CONCLUSIONS IFM related to the removal of teeth is a rare complication. Identifying and addressing the risk factors will enable the surgeon to avoid the complication of IFM associated with exodontia.
