Objectives: This study aimed to determine the prevalence of odontogenic cysts, tumors, and other lesions among reports in the archives of the Department of Oral and Maxillofacial Surgery at the Faculty of Dentistry affiliated with Kocaeli University collected over a four-year period. Materials and Methods: In this retrospective study, patient records from the archive of the Department of Oral and Maxillofacial Surgery from 2014 to 2018 were reviewed. Patient demographic information (age and sex) and lesion location were recorded and analyzed. Results: From a total of 475 files reviewed, odontogenic cyst was confirmed in 340 cases (71.6%), and odontogenic tumor was confirmed in 52 cases (10.9%). Regarding odontogenic cyst type, the most common was radicular cyst (216 cases), followed by dentigerous cyst (77 cases) and odontogenic keratocyst (23 cases). Among odontogenic tumors, the most frequent was odontoma (19 cases), followed by ossifying fibroma (18 cases) and ameloblastoma (9 cases). Giant cell granuloma was also reported in 35 cases. Conclusion:The distribution pattern of odontogenic cysts and tumors in our retrospective study is relatively similar to that reported in the literature. Complete clinical reports for final diagnosis of these lesions and routine follow-up examinations are very important for treatment.
Objectives: This randomized controlled trial aimed to compare crestal bone loss (CBL) and buccal bone thickness (BBT) around triangular cross-section neck (TN) to round neck (RN) implants retaining mandibular overdentures one year after loading, using cone beam computed tomography (CBCT).Material and Methods: Twenty edentulous patients receiving 40 implants with similar diameters were randomly assigned to the RN and TN groups. Clinical buccal bone thickness (CBBT) around the implants was measured with a caliper at baseline. A resonance frequency analyzer was used to measure the implant stability quotient (ISQ) at the baseline and two months after insertion. Pocket probing depths (PPD), plaque index (PI), and gingival index (GI) were also recorded at postoperative months 2, 6, and 12. CBCT was used to evaluate proximal CBL and BBT at three levels (0, −2, and −4 mm) one year after loading.Results: No implant loss was observed during the follow-up period. No significant differences in CBBT, ISQ values, and scores for PPD, PI, and GI between the two groups were observed at any time (p > .05). BBT was also comparable one year after loading (p > .05). The mean ± SD proximal CBL one year after loading was 0.58 ± 0.36 mm for TN and 0.91 ± 0.59 mm for RN (p < .01). Conclusions:This study found better crestal bone preservation in the implants with the novel neck design than conventional neck design in the anterior mandible after a follow-up of one year. However, it may not be clinically noticeable.
Objectives: The aim of this study was to evaluate correlations between anxiety and preoperative pressure pain assessments and postoperative pain and analgesic requirements in impacted lower third molar tooth surgery. Materials and Methods: This prospective study enrolled 60 patients who underwent impacted lower third molar surgery. The preoperative State-Trait Anxiety Inventory-I (STAI-I), pressure pain threshold, and pressure pain tolerance scores were measured. At 2, 4, 6, 12, and 24 hours, and at 6 days following surgery, the patients scored their pain on the visual analogue scale and recorded their analgesic drug usage. The data were evaluated, and the results were statistically analyzed. Results: Of the 60 patients, 38 were female. Mean age was 24.62±7.42 years. The study found no relationship between preoperative pressure pain assessments and postoperative pain (P>0.05). There was also no relationship observed between preoperative STAI-I scores and postoperative pain (P>0.05). However, there was a positive correlation between operation time and total medication taken (P<0.05). Conclusion: Preoperative pressure pain threshold, pressure pain tolerance, and anxiety level had no significant effects on postoperative pain and analgesic requirements in impacted lower third molar surgery.
IntroductionLymphomas are a heterogeneous group of malignant neoplasms of lymphocytes and their precursor cells. Lymphoma is seen 3.5% of all intraoral malignancies and is the second most common neoplasm after the squamous cell carcinoma in the head and neck region. Diffuse large B‐cell lymphomas (DLBCL), which is a subtype of non‐Hodgkin lymphoma, are seen mostly in the paraoral region.Case presentationAn 82‐year‐old woman was referred with a localised swelling of the mandibular buccal mucosa for 3 months. Excisional biopsy revealed the diagnosis of DLBCL in the mandible and chemotherapy regimen started immediately. However, patient died during treatment.ConclusionsNon‐Hodgkin's lymphomas would be late‐ or misdiagnosed in the perioral region that may result poor prognosis.
Background The aim of this randomized, triple-blind trial was to determine the anesthetic, analgesic, and hemodynamic effects of articaine and bupivacaine in the extraction of impacted mandibular third molar teeth. Methods Twenty-six patients who underwent removal of bilaterally symmetric mandibular third molars were randomly assigned to articaine and bupivacaine groups in a split-mouth design. The onset of anesthetic action, intraoperative comfort, total amount of solution used, duration of postoperative anesthesia and analgesia, rescue analgesic use, postoperative pain, intraoperative bleeding, and hemodynamic parameters were evaluated. Results In the articaine group, the onset of anesthetic activity was faster, intraoperative comfort was greater, and effective anesthesia required less local anesthetic solution. The bupivacaine group showed a significantly longer duration of postoperative anesthesia and analgesia, in addition to lower visual analog scale values at 6 and 48 hours postoperatively. There were no significant differences between the two solutions regarding rescue analgesic medication use, intraoperative bleeding, or hemodynamics. Conclusion Articaine showed greater clinical efficacy than bupivacaine in intraoperative anesthesia, achieving faster onset of anesthetic action and greater patient comfort while also requiring less reinforcement during surgery. However, bupivacaine was superior in terms of postoperative anesthesia, reducing postoperative pain due to its residual anesthetic and analgesic effects. Both anesthetic solutions led to similar hemodynamics at low doses in mandibular third molar surgery.
Purpose: The aim was to assess the knowledge, attitudes and anxiety of the dentists in relation to COVID-19. Materials and methods: This cross-sectional survey was conducted amongst 590 dentists employed in Turkey from March to April 2020. The electronic survey consisted of 22 questions related to demographic profile, knowledge, clinical practice and anxiety level of the participants towards dental management of COVID-19. The survey was sent to participants by email and mobile phone messages to be filled electronically. Results: Majority of respondents pointed to aerosol (98.5%), saliva (90.6%) and mucosal contact (71.4%) as the transmission routes of COVID-19. Amongst all clinical symptoms of the disease questioned, fever (99.8%), dry cough (99.1%), fatigue (90.0%) were associated with COVID-19 by vast majority of population. 96.4% of respondents agreed the usage of gloves as personal protective equipment and it was followed by face shield (88.1%), disposable gown (83.4%), protective goggles (73.9%). Increased usage of FFP2/N95 (33.9%) and FFP3/N99 (10.9%) respirators, contrary to reduction of surgical mask usage (50.7%), were observed in aerosolgenerating procedures comparing to dental procedures without producing aerosol and these differences were highly significant (p<0.001, p=0.004, p<0.001). The mean anxiety level of respondents was 3.35 ± 1.18 (ranging from 0 to 5). Conclusion: These results demonstrated an adequate knowledge, especially in clinical symptoms of COVID-19 amongst dentists. However, the respirator usage rate in aerosol-generating procedures was not satisfactory which suggesting to necessity of dentists’ education about pandemic.
