Conservative Management of Odontogenic Fibromyxoma of the Maxilla: A Case Report.

Odontogenic fibromyxoma typically presents as painless swelling in the jaw, and clinically, it grows slowly, becoming benign and asymptomatic. It causes the cortical plates to expand gradually, which leads to mobility and drifting of the teeth. Root resorption is also common. The tumor is locally aggressive in nature. It is also known to have a high recurrence rate. We present the case of a 30-year-old female patient who was diagnosed and treated for odontogenic fibromyxoma of the maxilla conservatively with enucleation. The radiograph showed a multilocular lesion, which can be confused with ameloblastoma, aneurysmal bone cyst, or odontogenic keratocyst. Hence, with proper clinical, radiographic, and histopathological examination, a correct diagnosis can be made and adequate treatment can be planned.

Assessment of Electromyographic Changes in Masseter and Temporalis Muscles for Patients Undergoing Lower Third Molar Surgery: A Prospective Study.

Introduction Lower third molar impaction surgery is one of the most common minor oral surgical procedures done. Trismus has been one of the most common and disturbing postoperative sequelae for patients. The study aimed to evaluate the electrical activity of the masseter and temporalis muscles after mandibular third molar surgery. Materials and methods The research was conducted at Saveetha Dental College and hospitals in the Department of Oral and Maxillofacial Surgery. The study consisted of 20 individuals. The EMG (electromyography) activities of both masseter muscles in each patient were measured before the tooth extraction surgery, postoperatively after 72 hours, and after seven days. The inter-incisal distance was also measured at similar follow-up intervals. Data were analyzed using IBM Corp. Released 2015. IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp., with p-values less than 0.05 considered statistically significant. The Mann-Whitney U test was used for the comparison of electrical activity between masseter and temporalis on both the operated and non-operated sides during preoperative, postoperative, 72-hour, and postoperative seven-day periods. Results It has been found that the electrical activity of the temporalis is higher than that of the masseter muscle measured at all the intervals of the follow-up period, with statistically significant values (p=0.001). It was noted that all the patients have reduced mouth opening when compared with preoperative (mean mouth opening = 45.6 mm), postoperative 72 hours (mean mouth opening = 31.2 mm), and postoperative seven days (mean mouth opening =35.6 mm). When a comparison was done between temporalis and masseter, the masseter took longer to return to pre-operative electrical activity, which might also imply that for prolonged trismus seen in patients after lower third molar surgery, it is the masseter that is affected and needs recovery for trismus to be resolved.  Conclusion  Based on the results obtained, it can be concluded that there was a reduction in the electrical activity of both the masseter and temporalis post-third molar impaction surgery. It was also found that there was a reduction in mouth opening in patients who underwent lower third molar extraction surgery. Masseter muscle took longer to return to its preoperative electrical activity than temporalis muscle, implying that targeted therapies to accelerate the healing of masseter muscle may prevent prolonged trismus in patients who undergo lower third molar impaction surgery.

Anatomical Basis for Preservation of Cartilaginous Apophysis in Pediatric Patients Undergoing Iliac Crest Bone Graft Harvest: A Cohort Study.

Background The anterior iliac crest is the workhorse for the harvest of cancellous bone in children undergoing cleft alveolar bone grafting. However, the complexity of the anatomy makes the process of harvesting graft technique sensitive. The aim was to describe the outcomes of the medially based trap door method of graft harvest in pediatric patients undergoing cleft alveolar bone grafting. Methods A cohort study was conducted, including all the patients in the age group of 8-12 years. Alveolar bone grafting was performed after harvesting a cancellous graft from the iliac crest bone grafting (ICBG) using a medially based trap door approach. Intraoperative time, average blood loss, and postoperative outcomes, including pain score, paresthesia, and gait disturbances, were recorded. Results A total of 28 patients were included in the study based on the inclusion and exclusion criteria. The volume of cancellous bone harvested was between 4-9 cc. The mean intraoperative time was 42 minutes, with an average blood loss of 36 to 48 ml. The average visual analog scale (VAS) score in the postoperative period was 3.5, 6, and 4 on the first, third, and seventh postoperative days. All the patients were ambulated on the second postoperative day, and none of them reported paresthesia. Long-term evaluation of the anterior illum revealed intact crestal morphology with a bone refill on the posterior-anterior (PA) pelvic X-ray. Conclusion A medially based modified trap door approach is more efficacious and less morbid for the harvest of ICBG in pediatric patients.

Comparison of the Efficacy of Two Different Local Anesthesia Techniques for Mesotherapy in Temporal Region Alopecia.

Introduction Mesotherapy is a wide range of minimally invasive injections. In mesotherapy, a mixture of various tonics is injected into the skin. These include plant extracts, various medications, vitamins, enzymes, hormones, growth factors, and other factors that will help treat alopecia. Most commonly, a mixture of platelet-rich plasma (PRP) and vitamins is used. In mesotherapy treatment for hair regrowth in the temporal region, zygomaticotemporal nerve blocks, supratrochlear nerve blocks, and supraorbital nerve blocks are given. The zygomaticotemporal nerve, supraorbital nerve, and supratrochlear nerve are the branches of the trigeminal nerve. They provide sensation on the lateral side of the forehead, which is the temple region.  Methods A sample size of 100 people was taken for the study who were undergoing mesotherapy in the bilateral temporal region for alopecia. Each group had 50 subjects: group I was given supratrochlear, supraorbital, and zygomaticotemporal nerve blocks as local anesthesia techniques, and group II was given supratrochlear and supraorbital nerve blocks. PRP was injected using an insulin syringe. Pain was assessed using a visual analog scale (VAS). Results During the procedure, a mean VAS of 1 and 3 was observed in groups I and II, respectively, during the procedure (p-value 0.023). A mean VAS of 3 and 5 was observed in groups I and II, respectively, after three hours (p-value 0.000). This shows a significant difference in the pain experienced by the subjects between the groups.  Conclusion This study proves that the zygomaticotemporal nerve, used along with supratrochlear and supraorbital nerve blocks, is better at producing analgesia and reducing pain.

Comparison of the Efficacy of Corticosteroids With Enzymatic Agents in the Postoperative Sequelae for Lower Third Molar Surgery: A Prospective Study.

Introduction The presence of impacted third molars is a prevalent problem associated with varying degrees of difficulty in extraction and potential consequences, including pain, swelling, and trismus. According to studies, enzymatic combinations, such as bromelain, rutoside, trypsin, and serratiopeptidase, are known to have a very promising role in reducing inflammation and promoting wound healing. This study compared natural enzymatic agents with corticosteroids for postoperative pain, swelling, and trismus in the impacted lower third molar surgery. Objectives The present study aimed to compare the efficacy of prednisolone, a combination of trypsin, chymotrypsin, bromelain, rutoside, and papain, and serratiopeptidase in the postoperative sequelae after surgical extraction of impacted mandibular third molars. The primary objective was to assess the difference in swelling between the three groups. The secondary objectives were to assess the difference in postoperative pain and trismus between the three groups. Materials and methods A total of 150 patients who presented to the department of oral and maxillofacial surgery for surgical removal of an impacted mandibular third molar with a moderately difficult score of 5-7 in the Pederson difficulty index were chosen for a prospective study. Patients were categorized into three groups based on the postoperative drug prescribed. In group 1, prednisolone 10 mg was prescribed; in group 2, a combination of trypsin, chymotrypsin, bromelain, rutoside, and papain was prescribed; and in group 3, serratiopeptidase 15 mg was prescribed. All patients were prescribed a combination drug of aceclofenac 100 mg and paracetamol 325 mg twice daily as a standard analgesic. Swelling, pain, and trismus in each patient were recorded preoperatively and at postoperative day one and day seven. The Friedman test was employed to evaluate the variation in pain levels within the groups over time, while the Kruskal-Wallis test was utilized to investigate the disparity in pain levels between the groups. The difference in swelling and trismus within the groups across the timeline was measured by repeated measures analysis of variance (ANOVA), and the difference in swelling and trismus between the groups was measured by one-way ANOVA. A p-value below 0.05 was deemed to be statistically significant. Results Group 1 showed less swelling, pain, and trismus on both postoperative day one and day seven compared to group 2 and group 3, which was a statistically significant difference (P < 0.05). It was found that swelling, pain, and trismus measurements in postoperative day one and day seven in group 2 were comparatively less than in group 3. Neither group demonstrated any side effects or other complications during the follow-up period. Conclusion It can be concluded that the use of prednisolone postoperatively following surgical removal of the mandibular third molar provided better relief with regard to pain, trismus, and swelling compared to the enzymatic agents. Among enzymatic agents, a combination of trypsin, chymotrypsin, bromelain, rutoside, and papain was better in reducing pain, trismus, and swelling than serratiopeptidase drug.

Regulation of hippo signaling mediated apoptosis by Rauvolfia tetraphylla in triple-negative breast cancer.

Rauvolfia tetraphylla is an essential medicinal plant that has been widely used in traditional medicine for various disease treatments. However, the tumor suppressor activity of R. tetraphylla and its phytocompounds were not explored against triple-negative breast cancer. The current research investigated the impact of R. tetraphylla methanolic extract (RTE) and its isolated compounds Ajmaline (RTC1) and Reserpine (RTC2) on triple-negative breast cancer cell line (MDA-MB-231) focusing on anti-proliferative effects. Our study imparts that RTE and RTC2 showed promising cytotoxic effects compared to RTC1. So further experiments have proceeded with RTE and RTC2, to evaluate its proliferation, migration, and apoptotic effect. The result shows around 80% of cells were observed in the G0/G1 phase in cell cycle analysis indicating the cell cycle inhibition and duel staining clearly showed the apoptotic effect. The migration of cells after the scratch was 60.45% observed in control and 90% in treated cells showing the inhibition of migration. ROS distribution was intense compared to control indicating the increased ROS stress in treated cells. Both RTE and RTC2-treated cells showed the potential to suppress proliferation and induce apoptotic change by upregulating BAX and MST-1 and suppressing Bcl2, LATS-1, and YAP, proving that deregulation of YAP resulting in the blockage of TEAD-YAP complex and inhibit proliferation. Therefore, R. tetraphylla extract and its isolated compounds were demonstrated to find its ability to act against MDA-MB-231 and these findings will help adjudicate it as a therapeutic drug against experimental triple-negative breast cancer.

Comparison of Efficacy of Platelet-Rich Plasma With and Without Topical Minoxidil for Hair Growth in Patients With Androgenetic Alopecia: A Prospective Study.

Introduction Androgenetic pattern of alopecia is a common problem occurring in men, which mostly arises from their younger age. There are many therapies advocated in the literature for hair loss reduction, and one of them is platelet-rich plasma (PRP) therapy. This study aimed to assess the efficacy of combined PRP therapy with topical minoxidil over PRP as monotherapy in hair loss reduction and regeneration of new hair. Materials and methods The study was conducted at our institute in the Department of Oral and Maxillofacial Surgery at Saveetha Dental College and Hospital. The study consisted of 40 participants, 20 of whom had only PRP therapy as part of their treatment, while the other 20 participants received PRP combined with topical minoxidil as treatment. Both group participants were evaluated for postoperative hair shaft diameter and hair follicle density. Parameters were measured preoperatively and postoperatively after one month, two months, and three months. Data analysis was done with the help of SPSS, with P-values less than 0.05 considered statistically significant. The Mann-Whitney U test was used to compare the two groups for measurement of hair shaft diameter, and for comparison between hair follicle density, an unpaired t-test was used. Results It was found that the mean hair shaft diameter in the PRP with minoxidil group was higher than that of the PRP group for one month (P = 0.023), two months (P = 0.001), and three months (P = 0.001) postoperative periods, and the results were statistically significant. Hair follicle density (mean hair quantity) was higher in the PRP group than in the PRP with the minoxidil group in the first postoperative month. However, this difference was not statistically significant (P = 0.08). While the mean hair quantity in the PRP with minoxidil group was higher than that in the PRP group for two months (P = 0.45) and three months (P = 0.001) postoperative periods, the results were statistically significant only at the three-month postoperative period. Conclusion It can be concluded that injectable autologous PRP with minoxidil as a topical agent is a better treatment option for the improvement of both hair quality (hair shaft diameter) and hair quantity (hair follicle density) compared to plain autologous injectable PRP monotherapy.

Comparison of the Efficacy Between Regional Nerve Block and Ring Block as Local Anesthetic Techniques for Platelet-Rich Plasma Treatment.

Introduction Platelet-rich plasma (PRP), a solution of concentrated platelets, has been widely used to promote wound repair and tissue regeneration. In the treatment of pattern hair loss, platelets in PRP secrete an abundance of growth factors, including platelet-derived growth factor (PDGF), fibroblast growth factor(FGF), and many more, which stimulate and increase signaling molecules and accelerate cell proliferation. In the PRP treatment for hair regrowth, the supratrochlear nerve (STN) block and supraorbital nerve (SON) block are given to anesthetize the scalp up to the vertex except for the temporal region. The ring block is the common local anesthetic technique used by infiltrating local anesthetic agents around the target area. The primary objectives were to compare the pain and anesthetic success rates produced by regional nerve blocks and ring blocks. Materials and methods A sample size of 100 patients undergoing PRP treatment for hair regrowth were taken as the subjects for the study. Patients were allotted into two groups by randomization. Group 1 was given regional nerve blocks as the anesthetic technique used for local anesthesia, and group 2 was given ring blocks. In the study group, STN and SON blocks as the regional nerve blocks were given 2% lignocaine with 1:80000 adrenaline to anesthetize the area, and the PRP was injected from the anterior hairline up to the vertex of the scalp, not involving the occipital and temporal regions. In the control group, a ring block was given for the same procedure. Participants from both groups were assessed for the pain and analgesia caused by ring block and regional nerve blocks using the visual analog scale (VAS). Results A mean rank of 30.28 was observed for the regional nerve block technique, and a mean rank of 70.72 was observed for the ring block technique. A p-value of 0.00 that is <0.05 was observed, which shows there is a significant difference in the pain and the analgesia experienced by the subjects between the two groups, during and three hours after the procedure. Conclusion PRP is one of the most commonly used treatments for hair regrowth. The ring block is the common local anesthetic technique used for producing anesthesia, while regional nerve blocks are more effective in producing local anesthesia. This study proves that STN and SON blocks are better anesthetic techniques than the ring block technique for PRP treatment in hair growth.

Comparison of the Effectiveness of a Novel Matrix-Modified Bovine Collagen Membrane With a Conventional Bovine Collagen Membrane for Oral Mucosal Defects: A Single-Center Study.

Background Surgical procedures such as excision of a growth or lesion lead to soft tissue or oral mucosal defects. These defects require a proper surgical dressing to promote better wound healing and to avoid infection and scarring. A collagen membrane is one of the most commonly used surgical dressings because of its ease of adaptability to defects and its inherent ability to promote epithelialization and inhibition of pain through the indirect mechanism of preventing infection of the surgical site. Collagen also serves as a reservoir of regenerative factors. The regenerative potential increases as porosity decreases. The novel bovine-derived collagen membrane used in this current study has an average porosity of 20 microns which increases the availability of regenerative factors. Objective  The aim of this study was to compare the effectiveness between a novel matrix-modified bovine collagen membrane (SurgiColl) and a conventional bovine collagen membrane for promoting wound healing for oral mucosal or soft tissue defects. Materials and methods This clinical trial was conducted in the Department of Oral and Maxillofacial Surgery, Saveetha Dental College and Hospital. The sample size of the study was 20, divided into two groups: novel bovine collagen (Surgicoll-Mesh) (Group 1) and conventional bovine collagen (Group 2) with 10 participants in each group. The randomization process was adopted. The parameters assessed were epithelialization, granulation, and wound contraction at the end of two weeks. All the parameters were assessed using a standardized visual assessment scale. Statistical analysis was done using IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States), and an independent sample t-test was done at 95% confidence interval. A p-value of less than 0.05 was considered statistically significant. Results The difference in epithelialization between the two groups was statistically significant with a p-value of 0.015 (<0.05). The difference in granulation tissue formation between the two groups was statistically significant with a p-value of 0.015 (<0.05). The difference in wound contraction at the end of two weeks between the two groups was also statistically significant with a p-value of 0.005 (<0.05). Group 1 showed superior results compared to Group 2 for all the outcomes assessed. Conclusion  The novel bovine-derived collagen membrane (SurgiColl-Mesh) was superior in its properties of wound healing for oral mucosal or soft tissue defects than the conventional bovine collagen membrane.

Efficacy of Different Techniques of the Inferior Alveolar Nerve Block for Mandibular Anesthesia: A Comparative Prospective Study.

Background The inferior alveolar nerve block (IANB) is a commonly employed technique in oral surgery for achieving profound anesthesia in the mandibular teeth and associated structures. Several techniques have been developed to enhance the success rate and patient comfort during the IANB. The aim of this study was to compare and evaluate the efficacy of different IANB techniques for mandibular anesthesia.  Materials and methods The participants included in the study were adults requiring surgical extraction of an impacted mandibular third molar teeth. A total of 100 participants were randomly assigned to five different groups representing various techniques of IANB, i.e., conventional Halsted technique, Vazirani-Akinosi technique, Gow-Gates technique, Fischer 1-2-3, and extraoral Kurt-Thoma technique, with 20 participants in each group. The participants were evaluated for the onset of anesthesia using subjective and objective methods, pain perception during the administration of local anesthesia using a 10-point visual analogue scale (VAS), and the incidence of trismus postoperatively. Data were analyzed using IBM SPSS Statistics for windows, version 23.0 (released 2015; IBM Corp Armonk, United States) with p-values less than 0.05 considered as statistically significant. Descriptive statistics, Kruskal-Wallis, and post-hoc tests were included in the data analysis for intergroup comparisons. Results The primary outcomes evaluated were the onset of anesthesia, the patient's perception of pain during the administration of local anesthesia, and the secondary outcome included in the incidence of trismus. In this study, it was found that the Kurt-Thoma technique had the fastest onset of anesthesia (2.25 minutes), higher incidence of trismus (25%), and higher pain perception (6.5 score on VAS). The conventional Halstead technique (3.55 minutes), Fischer 1-2-3 technique (3.5 minutes), and Vazirani-Akinosi technique (3.1 minutes) had an almost similar mean duration of anesthesia. The onset of anesthesia was delayed in the Gow-Gates technique (5.1 minutes). Patient perception of pain during administration of local anesthesia was higher in the Kurt-Thoma (6.5) and Gow-Gates techniques (4.95), and it was least in the Fischer 1-2-3 technique (0.75) in the VAS scores. The incidence of trismus was highest with the Kurt-Thoma technique (25%), then the Gow-Gates technique (20%), followed by the conventional Halstead technique (5%).  Conclusion In this study, it was found that the conventional Halsted technique was the best among the different techniques of IANB and remains the gold standard.

Effectiveness of Advanced Platelet-Rich Fibrin on Postoperative Sequelae for Impacted Mandibular Third Molar Surgery: A Prospective Study.

Introduction Impacted third molar extraction is frequently removed surgically by maxillofacial surgeons, which is mostly associated with postoperative sequelae like pain and swelling. It is essential to minimize the complications and enhance wound healing in the extracted socket of the third molar. Hence, this study aimed to assess the efficiency of advanced platelet-rich fibrin (A-PRF) in wound healing and reducing pain after surgical extraction of the impacted mandibular third molar (IMTM). Materials and methods Thirty healthy patients who have been diagnosed with Pell and Gregory class II IMTM were included in this study. In the study group, which comprises 15 patients, extraction sockets were filled with A-PRF extract. In the control group, no material was placed in the extraction sockets. The pain was assessed preoperative and on the third and seventh postoperative days using a visual analog scale (VAS). Wound healing was assessed on the third and seventh postoperative days using a modified laundry scale. SPSS for Windows was used for data analysis. Categorical data was compared between the groups using the Chi-square test. P-value less than 0.05 was considered as statistically significant. Results The study population's mean age was 25.67 ± 2.4 years. Nineteen patients were male, and 11 patients were female. Differences in mean pain scores between the groups were not statistically significant both on the third postoperative day (p=0.59) and the seventh postoperative day (p=0.33). During the seventh day postoperative day, the study group exhibited better wound healing compared to the control group and the results were statistically significant (p=0.01). Conclusion A-PRF is a simple and effective method of reducing postoperative sequela by promoting wound healing after surgical extraction of IMTM. It has the advantage of less chance of allergic and anaphylactic reactions, unlike their predecessor platelet concentrates.

Efficacy of Oxytetracycline Hydrocortisone-Soaked Gauze Pack on Postoperative Sequelae in Lower Third Molar Surgery: A Prospective Study.

Background Though various advancements came into the field of surgery to do the atraumatic procedure, post-operative pain, and swelling are unavoidable complications. Hence, various medicaments are packed in the extracted third molar sockets to prevent these post-operative complications. Aim The study aimed to evaluate the efficacy of oxytetracycline hydrocortisone-soaked gauze in reducing post-operative pain and swelling compared to conventional surgical procedures without any packing in patients undergoing surgical extraction of the impacted mandibular third molars. Materials and methods The study was conducted in the Department of Oral and Maxillofacial Surgery at Saveetha Dental College and Hospitals, Chennai. In this study, 50 patients were randomly included in two groups of 25 participants each. In group A, oxytetracycline hydrocortisone-soaked gauze was placed, and in group B, conventional closure was done without any pack after surgical removal of impacted mandibular third molars. Post-operative pain was assessed on days one, three, and five using a 10-point visual analog scale. Post-operative swelling was assessed on the third and seventh days using a four-point swelling measurement. Data analysis was done using SPSS (IBM Corp. Armonk, NY). A p-value less than 0.05 was considered statistically significant. Independent sample t-test was done to compare the outcomes between the two groups. Results The results demonstrated that group A (Oxytetracycline Hydrocortisone-soaked gauze) showed superior pain reduction compared to group B (conventional closure) at all post-operative intervals (P=0.001). Moreover, group A exhibited reduced swelling, resulting in higher patient satisfaction levels compared to group B on the third post-operative day (P=0.001). Conclusion It can be concluded from the study that there was a significant reduction in post-operative pain and swelling with the use of oxytetracycline hydrocortisone-soaked gauze, as it acts like a local drug delivery system in patients undergoing impacted mandibular third molar surgeries.

Network pharmacology integrated with molecular docking reveals the anticancer mechanism of Jasminum sambac Linn. essential oil against human breast cancer and experimental validation by in vitro and in vivo studies.

Jasminum sambac L. (J. sambac) belongs to the family Oleaceae and it is an ornamental subtropical evergreen shrub used in traditional treatments of certain ailments and diseases. This study aimed at devising an integrated strategy attempts to evaluate the bioactive components in the J. sambac essential oil (JEO) against human breast cancer. JEO extracted by distillation process and analyzed by GC-MS was subjected to screening of therapeutic components in their allegiance to the drug-likeness index. The utility and efficacy of its molecular mechanism relating to anticancer potential were probed with network pharmacology analysis. Gene ontology, pathway enrichment, and compound-target-pathway network by Cytoscape helped to harp on hub targets and pathways involved in curative action. Drawing from the network data, molecular docking analysis of selected compounds on breast cancer targets was approached. The anti-proliferative study was carried out in MCF-7 and MDA-MB-231 to evaluate the cytotoxicity of JEO. Finally, in vivo anticancer activity was verified using rat models. The results showed MDA-MB-231 cell growth was highly inhibited than the MCF-7 cell line. Alongside this in vitro trial, in situ effectiveness of JEO was evaluated using female Sprague-Dawley rat animal models. In vivo experiments and histopathological analysis showed convincing results in DMBA tumor-induced rats. The larger aim of this study is to identify the potential ingredients of the JEO in cancer apoptosis by integrating network pharmacology and experimental validation achieved to certain extent confers credence to the concept of hiring J. sambac as floral therapy in dealing with the disastrous disease.

Unusual Presentation of Primary Hyper-IgE-Related Salivary Gland Disease in a 13-Year-Old Male.

Adenomas are common pathologies of the salivary glands that are often associated with the major salivary glands and occur in the fourth to sixth decades of life. They are seldom seen in the pediatric age group and rarely in the minor salivary glands. Autoimmune sialadenosis of the minor salivary glands is a new phenomenon that has seldom been reported in the literature, with as few as three cases. Histopathological examination of the excised specimen is the definitive diagnosis, and these lesions have to be differentiated from adenomas and low-grade malignancies of the minor salivary glands. Management strategies of these lesions are extremely variable, ranging from wait-and-watch principle to the use of immunosuppressants and excision of the gland. This case report discusses the etiopathogenesis of the autoimmune sialadenosis and the management strategies.

Comparison of Pain Perception Between Local Infiltration and Inferior Alveolar Nerve Block Injection Techniques in Patients Undergoing Orthodontic Lower Premolar Extractions.

Introduction The most frequently used local anesthesia administration techniques for extraction of lower teeth in dentistry are local infiltration and inferior alveolar nerve block. Therapeutic extraction of premolars is the most common procedure done for patients undergoing orthodontic treatment. Inferior alveolar nerve block has been used most commonly for extraction of mandibular posterior teeth; however, it is a technique-sensitive procedure and has complications such as facial nerve palsy, trismus, and long duration of anesthesia. Local infiltration is a simple and effective technique for anesthetizing teeth prior to extraction. Aim This study aims to compare the efficacy of local anesthesia administered through inferior alveolar nerve block and local infiltration techniques for extraction of lower premolar teeth for orthodontic purposes. Materials and methods A prospective comparative study was conducted for a period of six months in which a total of 100 patients who were referred for extraction of lower premolar teeth for orthodontic purposes were included. Among 100 patients, 60 patients were males, and 40 patients were females with a mean age of 16.5 ± 1.25 years. The patients were equally divided into two groups, in which Group 1 received local infiltration and Group 2 received an inferior alveolar nerve block. The outcome parameters assessed were pain during injection and pain during extraction using the visual analog scale (VAS) score and Wong-Baker Faces Pain Rating Scale score. Statistical analysis was done using an independent sample t-test with SPSS version 23.0 software (IBM Corp., Armonk, NY) at p < 0.05 considered statistically significant. Results The difference in mean pain scores between the two groups during injection as assessed using the Faces Pain Rating Scale (p = 0.001) and VAS (p = 0.001) was statistically significant, with the infiltration group exhibiting less pain than the inferior alveolar nerve block group. The difference in mean pain scores between the two groups during extraction as assessed using the Faces Pain Rating Scale (p = 0.308) and VAS (p = 0.350) was statistically not significant, with the infiltration group not significantly differing from the inferior alveolar nerve block group. Thus, the pain during local infiltration was significantly lesser when compared to the inferior alveolar nerve block during injection, whereas pain perception during extraction was similar in patients with both injection techniques. Conclusion It can be concluded that local infiltration is less painful for the patient during injection and as efficacious as nerve block for extraction, hence local infiltration can be routinely used for lower premolar orthodontic extractions.

Comparison of the Efficacy of Midazolam and Dexmedetomidine As Sedative Agents in Third Molar Surgery.

Introduction Minor dental and oral surgical procedures have been made comfortable with the rise in the use of daycare sedatives. Of these sedatives, midazolam is deemed a common sedative used for minor oral surgical procedures. Newer and safer sedatives such as dexmedetomidine have certain properties that may prove more efficient in oral surgical procedures. Third molar surgery is one of the most common minor oral surgical procedures performed in dentistry. Thus, this study aims to compare the efficacy of midazolam and dexmedetomidine as sedative agents in third molar surgery. Materials and methods Sixty young adult patients free from other comorbidities were included in the study with ages ranging between 18 and 50 years. The samples were matched for the difficulty of impacted teeth and randomly distributed among the groups. Groups were administered the respective sedative drugs midazolam and dexmedetomidine and their effects were observed through the Observer's Assessment of Alertness/Sedation scale. The intraoperative vitals and sedation effects were checked every 15 minutes. Statistical analysis was done using IBM SPSS Statistics for Windows, Version 22 (Released 2013; IBM Corp., Armonk, New York, United States). Independent samples t-test and analysis of variance were the statistical tests employed to analyze the obtained data with p<0.05 considered as statistically significant. Results The depth of sedation has been both subjectively and objectively assessed and had no significant difference among the groups. The intra-operative heart rate assessment proved a more efficient reduction of pulse rate in the dexmedetomidine group as compared with the midazolam group. However, it was not statistically significant (p=0.121). The mean diastolic blood pressure showed a statistically significant difference between the groups with dexmedetomidine having lower blood diastolic pressure compared to midazolam (p=0.004). Quick arousal was witnessed in the dexmedetomidine group. Conclusion It can be concluded from the study that both dexmedetomidine and midazolam were equally effective as sedative agents for third molar surgery. However, the nature of cardio-protection, anti-sialagogue, and analgesic properties of dexmedetomidine can prove helpful, especially in minor oral surgical procedures like third molar surgery and it is recommended.

Microbiological Evaluation of Four Different Suture Materials Used for the Surgical Removal of Impacted Lower Third Molars: A Single-Center Prospective Comparative Study.

Introduction Sutures play a crucial role in the postoperative healing process, as they help approximate wound edges, promote hemostasis, and support tissue healing. The oral cavity harbors a diverse microbial population, and oral surgical procedures can introduce potential pathogens into the surgical site. Understanding the impact of suture material on wound infection rates and the colonization of potentially harmful microorganisms is vital for improving patient outcomes. This study was aimed to evaluate and compare the microbiological properties of prolene, vicryl plus, monocryl, and silk sutures used after the surgical removal of impacted lower third molars. Materials and methods A total of 40 patients requiring surgical extraction of impacted lower third molars were assigned to four groups: prolene, vicryl plus, monocryl, and silk sutures. Surgical extraction of impacted tooth was done, and wound was sutured with the abovementioned four different materials in four groups, respectively. After seven days, the sutures were removed and sent to the microbiology lab for colony count assessment. Total microbial colony count, streptococcus count, and lactobacillus count were assessed. Data was analyzed using IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States) with p-values less than 0.05 considered as statistically significant. The one-way analysis of variance (ANOVA) and post-hoc Tukey test were done to compare intergroup relations. Results The microbiological evaluation of the sutures revealed significant differences in bacterial colonization among the four groups. More bacterial quantities were found in the silk group followed by the monocryl, vicryl plus, and prolene groups in the descending order. Prolene demonstrated the lowest incidence of bacterial growth (p<0.001) compared to vicryl plus, monocryl, and silk sutures. Bacterial colony count was highest in the silk group. The predominant bacterial species found in all groups were Streptococcus viridans, Staphylococcus aureus, and Lactobacillus.  Conclusion It was found that prolene and vicryl plus sutures exhibited superior microbiological properties compared to monocryl and silk sutures when used for the surgical removal of impacted lower third molars. The lower incidence and less quantity of bacterial colonization on prolene sutures suggest their potential for reducing the risk of postoperative infection; hence, these sutures can be preferred for oral surgical procedures.

Comparison of Pain Levels With Postoperative Intramuscular Administration of Single-Dose Ketoprofen Versus Diclofenac Sodium in Patients Undergoing Lower Third Molar Surgery.

Background Third molar surgeries are commonly performed in oral and maxillofacial surgery practice. Pain associated with this procedure is usually a frequent reason for patient apprehension and discomfort. Oral analgesics, though effective, do not provide sufficient pain relief in the immediate postoperative period.  Aim To assess the postoperative effect on pain levels of single-dose administration of ketoprofen and diclofenac sodium as an injection in patients undergoing third molar removal surgeries.  Methods This study was conducted among 30 patients divided into two groups (n=15). Patients in Group K received injection ketoprofen 100 mg and Group D included patients receiving injection diclofenac sodium 75 mg, both intramuscularly postoperatively. The intensity of pain was assessed at 30 minutes, two, six, and eight hours post-surgical removal of the impacted tooth using the visual analogue scale (VAS). The statistical data was analyzed using SPSS for Windows version 23.0 (IBM Corp., Armonk, NY, USA). The comparative statistical test adopted to compare pain scores between the two groups was the Independent samples t-test. A p-value of <0.05 was considered to be statistically significant. Results Our study results revealed that Group K patient's VAS scores after two hours, six hours, and eight hours were 3.9 ± 2.7, 4.5 ± 3.23, 2.93 ± 2.27 respectively. In Group D patient's VAS scores after two hours, six hours, and eight hours were 4.83 ± 2.82, 5.03 ± 2.9, 3.73 ± 2.91 respectively. Patients who were administered ketoprofen had lower pain levels when compared to patients who were given diclofenac but the difference was not statistically significant at any time point (p=0.172 after eight hours). Our results depicted that the pain levels uniformly reached their maximal levels six hours after the procedure and thereafter steadily declined in both groups.  Conclusion It can be concluded from the study that both the drugs ketoprofen and diclofenac sodium analyzed in this study can be used interchangeably for the reduction of pain following lower third molar surgery.

Efficacy of Dexamethasone Diluted Saline Irrigant on Postoperative Sequelae in Patients Undergoing Lower Third Molar Surgery: A Prospective Clinical Study.

Background Third molar impaction surgery is one of the most common yet challenging procedures done as a part of minor oral surgery. Years of research and improvisation of techniques have been done, yet there are still a lot of postoperative sequelae after surgical removal of the impacted tooth. In our study, we have compared the efficacy of dexamethasone diluted saline solution over plain saline solution used as an irrigant in the reduction of postoperative sequelae for lower third molar surgery. Aim The aim of the study was to evaluate the efficacy of dexamethasone diluted saline solution over plain saline solution in the reduction of postoperative sequelae for lower third molar surgery. Materials and methods The research was conducted at Saveetha Dental College and Hospital in the Department of Oral and Maxillofacial Surgery. The study consisted of 48 individuals, 24 of whom had dexamethasone saline as an irrigant (8 mg of dexamethasone was diluted in 100 ml of plain saline) (Group 1), and 24 in whom plain saline was used as an irrigant (Group 2) in the lower third molar surgery. Patients were evaluated postoperatively for pain and swelling. The postoperative swelling was measured on postoperative day two and day seven. Postoperative pain was measured on day two, day four, and day seven after surgery using a visual analog scale. Data were analyzed using SPSS (IBM Corp., Armonk, NY) with P-values less than 0.05 considered statistically significant. The statistical test used to compare the outcomes between the two groups was the independent samples t-test. Results It was found that study participants in the dexamethasone saline irrigation group reported statistically significantly lesser pain than participants receiving plain saline irrigation on day two (P = 0.001), day four (P = 0.001), and day seven (P = 0.001), respectively. Also, there was a reduction in swelling among participants in the dexamethasone saline irrigation group when compared to the normal saline irrigation group, which was statistically significant (P = 0.001) on day two, while the postoperative swelling was not statistically significant on day seven (P = 0.08) between the two study groups. Conclusion Based on the results obtained, it can be concluded that dexamethasone saline solution (8 mg/100 mL) was more effective as an irrigant in reducing the postoperative sequelae than regular saline solution in the lower third molar surgery.

Efficacy of Eutectic Mixture of Local Anesthetics (EMLA) Versus Ice as Topical Anesthetics Prior to Long Buccal Nerve Blocks: A Prospective Comparative Study.

Background Dental extraction is one of the common procedures in the field of dentistry. However, fear and anxiety about local anesthetic injections are unavoidable for most patients. Topical anesthetics, distraction techniques, acupuncture, and the application of heat or cold have been used in practice to alleviate injection-related pain. The specific aim of this study was to compare the pain-relieving efficacy of eutectic mixture of local anesthetics (EMLA) vs. ice during the administration of a long buccal nerve block (LBNB) before dental extraction. Materials and Methods In total, 20 healthy adult patients who required bilateral mandibular posterior teeth extraction under local anesthesia were enrolled. The study was conducted in the Department of Oral and Maxillofacial Surgery, Saveetha Dental College and Hospitals, Chennai, from January 2023 to May 2023. It was a prospective split-mouth study in which each participant was divided into two groups according to the operative site: Group 1, which received a 5% EMLA cream, and Group 2, which received an application of ice before administration of LBNB. There was a one-week interval between the two interventions. The levels of pain and satisfaction were assessed using the visual analogue scale (VAS) and pain perception was evaluated by the sound, eye, motor (SEM) scale. Mann-Whitney U test was applied for the statistical analysis. Results The study included a total of 20 participants, with 14 being male and six being female. The mean age of the study population was 42 ± 15 years. When analyzing the pain scores using the VAS, it was found that Group 1 had a mean score of 2.4 ± 0.44, while Group 2 had a mean score of 3.0 ± 0.44. This difference between the two groups was statistically significant (P = 0.001). It was also found that the mean patient satisfaction score for Group 1 was 9.8 ± 0.22 and for Group 2 was 9.2 ± 0.40 which was statistically significant (p = 0.003). Similarly, Group 1 had a mean SEM score of 1.1 ± 0.1, while Group 2 had a mean SEM score of 1.30 ± 0.46 which was also statistically significant (P =0.016). Conclusion The study results revealed that EMLA has a significant advantage over ice in terms of lower levels of pain, more patient satisfaction, and higher comfort levels. EMLA can be considered the first choice of topical anesthetics, however, ice is recommended in resource-constrained dental set-ups as it is cost-effective.
