Pathologic changes in soft tissues associated with asymptomatic impacted third molars.

OBJECTIVE The aim of this study was to examine the need for routine removal of asymptomatic impacted third molars under the prophylactic indication, based on the incidence of pathologic changes. The frequency and type of pathologic conditions associated with impacted third molars were also evaluated. STUDY DESIGN One hundred twenty impacted third molar dental follicles were submitted for histopathologic examination. The association between dental follicles and pathologic changes, age, gender, and angular position were statistically evaluated. RESULTS Among these dental follicles, pathologic conditions were found in 23%. The relation between pathologic changes and angular position was not statistically significant (chi(2) = 2.040; P > .05). Pathologic changes were seen mostly in women who were > or = 20 years old. CONCLUSIONS Cystic changes may be developed in asymptomatic impacted third molars. Asymptomatic impacted third molars should be removed before pathologic changes can occur.

Proinflammatory cytokines in temporomandibular joint synovial fluid before and after arthrocentesis.

OBJECTIVE The aim of this study was to evaluate the levels of interleukin (IL)-1beta, IL-6, IL-8, IL-11, and tumor necrosis factor (TNF)-alpha in temporomandibular joint (TMJ) synovial fluid of the patients with internal derangement before and 2 weeks after arthrocentesis. STUDY DESIGN Forty TMJs of 35 patients (29 females and 6 males, mean age 22.9 years) were included to the study. TMJs were divided into 2 groups: disc displacement with reduction (Group 1, n = 24) and disc displacement without reduction (Group 2, n = 16). Synovial fluid samples were obtained before and 2 weeks after arthrocentesis. IL-1beta, IL-6, IL-8, IL-11, and TNF-alpha concentrations were measured by using specific kits. RESULTS Two weeks after the arthrocentesis procedures, all cytokines were found to be significantly decreased (P < .05) both in Group 1 and Group 2. The difference between 2 groups was insignificant (P > .05). CONCLUSION Arthrocentesis is an effective technique for eliminating the studied cytokines from the TMJ synovial fluid.

Comparison of stability of titanium and absorbable plate and screw fixation for mandibular angle fractures

OBJECTIVE The purpose of this experimental study was to compare the stability of titanium and absorbable plate and screw fixation systems for mandibular angle fractures. STUDY DESIGN Twenty-one sheep hemimandibles were used to evaluate 3 different plating techniques. The groups were fixated with a single titanium plate, a single absorbable plate and double absorbable plates. A cantilever bending biomechanical test model was used for the samples. Each group was tested with vertical forces by a servohydraulic testing unit. The displacement values in each group at each 10 N stage up to 100 N were compared using the 2-way analysis of variance test. RESULTS The displacement values for the 3 groups differed significantly (P < .05). The variance analyses showed that titanium plate placement had more favorable biomechanical behavior than others. In addition, the 2 absorbable plates group had more favorable biomechanical behavior than a single absorbable plate group but it was not significantly different at 10 to 40 N. CONCLUSION The study demonstrated that titanium plate and screw fixation system had greater resistance to occlusal loads than absorbable plate and screw systems. In addition, a second absorbable plate orientation provides a more favorable biomechanical behavior than a single absorbable plate placement.

Conservative Treatment Protocol for Keratocystic Odontogenic Tumour: a Follow-up Study of 3 Cases

ABSTRACT Background The keratocystic odontogenic tumour is classified as a developmental cyst derived from the enamel organ or from the dental lamina. The treatment of keratocystic odontogenic tumour of the jaw remains controversial. The aim of this study was to report the outcome of our conservative treatment protocol for keratocystic odontogenic tumour. Methods Three patients with different complaints referred to Oral and Maxillofacial Surgery Clinic, Faculty of Dentistry, Selçuk University. Initial biopsy was carried out in all patients and keratocystic odontogenic tumours was diagnosed subsequent to histopathological examination. The patients with keratocystic odontogenic tumours were treated by enucleation followed by open packing. This conservative treatment protocol was selected because of existing young aged patients. The average follow-up duration of the cases was 2 years. Results Out of 3 cases, 2 lesions were present in mandible and 1 lesion in maxilla. There was no evidence of recurrence during follow-up. All the cases were monitored continuously with panoramic radiographs, computed tomography and clinical evaluations. Conclusions This conservative treatment protocol for keratocystic odontogenic tumours, based on enucleation followed by open packing would be a possible choice with a view of offering low recurrence rate and low morbidity rate particularly in young patients.

Complex Midfacial Reconstruction With an Implant-supported Framework

This clinical report describes the treatment of a patient with osseointegrated extraoral implants supporting a framework retainer and acrylic resin mesostructures and a large silicone midfacial prosthesis. A metal framework was used to splint the implants together and provided satisfactory retention for the facial prosthesis. A 2-piece prosthesis that composed of an obturator and facial prosthesis was fabricated. Cosmetic improvements as well as the ability to speak, swallow, and, to a lesser degree, chew, were achieved for this patient.

Comparison of the efficacy of low doses of methylprednisolone, acetaminophen, and dexketoprofen trometamol on the swelling developed after the removal of impacted third molar

Background The aim of the present study was to compare the efficacy of low doses of methylprednisolone, acetaminophen and dexketoprofen trometamol, which are among the drug groups used in our clinic, on postoperative swelling developing after removal of impacted third molar. Material and Methods The three group of patients received either 40 mg methylprednisolone or 300 mg acetaminophen or 12.5 mg dexketoprofen trometamol one hour before the procedure, according to the patient groups. The patients in the methylprednisolone group were injected with methylprednisolone at a dose of 20 mg 24 hour after the procedure and prescribed 300 mg acetaminophen as rescue analgesic. During the postoperative period, the doses that were given before the procedure were continued 3 times a day for 2 days in the acetaminophen and dexketoprofen trometamol groups. Maximal swelling was assessed preoperatively and at the postoperative 48 hours by ultrasound images. Results Swelling was 34% lower in the methylprednisolone than in the other groups; however, no statistically significant difference was found between the groups. The acetaminophen and dexketoprofen trometamol groups exhibited clinical results close to each other. Conclusions Combination of low doses of methylprednisolone and acetaminophen provide a safe and adequate clinical success on swelling. Key words: Methylprednisolone, acetaminophen, dexketoprofen trometamol, third molar extraction, swelling.

Association of Serum Total Antioxidant Capacity and Total Oxidant Status with Pain Perception in Patients with Myofacial pain Dysfunction

We aimed to find out the association of total antioxidant capacity (TAC) and total oxidant status (TOS) with generalized pressure pain thresholds (PPT) of patients with myofacial pain dysfunction (MPD). PPT scores of patients with MPD (n = 37) and healthy individuals (n = 43) were measured on the hypothenar region of the hand using a mechanical algometer. Serum samples were collected and TAC and TOS were measured by novel methods. The TAC of patients was significantly lower than that of the control subjects. The difference between the TOS measurements of patients and control subjects was not significant. The PPT scores of the patients were significantly lower than that of control subjects. There may be an association between serum antioxidant capacity and MPD. Low serum TAC might also be related with pain perception.

Evaluation of Related Factors in the Failure of Endodontically Treated Teeth: A Cross-sectional Study

Introduction: The aim of this study was to review the factors related to the failure and extraction of unsuccessful endodontically treated teeth. Methods: A total of 1000 teeth treated with nonsurgical root canal therapy were analyzed, and the following information was recorded for each patient: reasons for failure and extraction, type of tooth, presence and type of coronal restoration, smoking status, age, gender, and level of education. One main reason was recorded for each failed tooth. The associations between reasons for failure, patient, and tooth were tested by using χ2 analysis. Results: Of the 1000 endodontically failed teeth analyzed in this study, 28.1% (n = 281) were extracted, 66% (n = 660) were re‐treated, and 5.9% (n = 59) were treated with apical surgery. Among the reasons for failure, restorative and endodontic reasons were seen most frequently (43.9%, n = 439), whereas orthodontic reasons were seldom seen (0.1%, n = 1). The most common reason for extraction was for prosthetic reasons (40.8%), and perforation/stripping was the least common (2.9%). The mandibular first molars were the most frequently extracted teeth (27.4%, n = 77). Conclusions: The most common reason for the extraction of endodontically treated teeth was for prosthetic reasons. Among the reasons for failure, restorative and endodontic reasons were the most frequently seen, and orthodontic reasons were the most seldom. The teeth that failed most frequently were mandibular first molars, and the teeth that failed least frequently were maxillary third molars. The most common reason for the extraction of failed endodontically treated teeth was for prosthetic reasons.

Factors affecting anxiety-fear of surgical procedures in dentistry

Aim: To compare dental anxiety and fear during procedures performed under local anesthesia either in the operating room or in the clinic as well as to investigate the potential factors that might influence this psychological condition. Subjects and Methods: Patients who were admitted to the Department of Oral and Maxillofacial Surgery of the universities in two cities, which have a different sociocultural patient profile, were enrolled. In addition to the State-Trait Anxiety Inventory (STAI), Dental Anxiety Scale (DAS), and Dental Fear Scale (DFS), the patients were asked to answer the questions concerning previous dental experience, education level, and previous psychiatric therapy. Statistical Analysis Used: The results of STAI were analyzed by Mann–Whitney U-test and results of DAS and DFS were analyzed by one-way analysis of variance test. Results: Two hundred patients, of whom 76 were enrolled in the first center and 124 were enrolled in the second center. A statistically significant difference was observed in state anxiety levels of the patients between the two centers, whereas the difference in trait anxiety levels was not significant. The results of DAS, DFS, and STAI-trait (STAI-T) displayed a significant difference between genders; the levels of anxiety and fear were higher in females than in males (DAS P = 0.025, DFS P = 0.017, STAI-T P = 0.045). Comparison between the patients with and without previous dental experience revealed a statistically significant difference regarding the results of STAI. Conclusions: The study found that sociocultural structure and gender are the significantly effective factors on dental anxiety and fear.

Arylesterase and Paraoxonase-1 Activities in Female Patients with Temporomandibular Disorders

Objective: The aim of this study was to assess a possible relationship between temporomandibular disorders [TMD] and serum levels of sulfhydryl [SH] groups and ceruloplasmin [CP], paraoxonase-1 [PON1], and arylesterase [ARE] activities. Method: This study included patients with TMD and healthy normal controls [HNC]. After clinical and radiographic examinations, the patient group was given a visual analog scale to determine severity of pain. Serum samples of the subjects were obtained to calculate certain antioxidant components. The CP, PON1, and ARE activities and serum levels of SH groups were measured. Results: There were 31 patients with TMD and 35 HNC. Serum levels of SH and ARE activity of the TMD group were significantly lower than those of the HNC group [P < 0.05]. The difference between CP and PON1 activity of the TMD and HNC groups were not statistically significant [P > 0.05]. No association was found between antioxidant levels and severity of pain and the type of the TMD. Conclusions: Antioxidant components may be associated with TMD, implying possible systemic inflammatory and oxidative aspect of TMD.
