Treatment of a calcifying epithelial odontogenic tumour with tube decompression: a case report

Conservative treatment of odontogenic tumours with decompression or marsupialisation is not common, but can be done successfully in those with a cystic pattern. We present a calcifying epithelial odontogenic tumour that was treated by tube decompression and subsequent enucleation. © 2018 The British Association of Oral and Maxillofacial Surgeon

Evaluation of New Bone Formation in Sinus Floor Augmentation with Injectable Platelet-Rich Fibrin-Soaked Collagen Plug: A Pilot Study

Introduction:The objective of this study is to evaluate the new bone formation after sinus floor augmentation with collagen plugs used as carriers for injectable platelet-rich fibrin (i-PRF).Materials and Methods:Postoperative immediate and postoperative 6th month panoramic radiographies of patients treated between January 1, 2015, and February 1, 2018, with sinus floor augmentation using i-PRF-soaked collagen plugs were retrieved from the archives, and subantral bone heights of distal and mesial regions of simultaneously inserted implants were measured with a software program. Statistical analysis was performed to understand whether there is a significant change in new bone formation at 6th month follow-up control.Results:A total of 18 implants were inserted in 12 patients. There was significant new bone formation at 6th month follow-up radiography at mesial and distal regions of inserted implants (P < 0.05).Conclusion:New bone was regenerated with i-PRF carried by collagen plugs in sinus floor augmentation.

Effect of platelet rich fibrin on edema and pain following third molar surgery: A split mouth control study

Background: To evaluate the efficacy of platelet-rich fibrine (PRF) on postoperative edema and pain after impacted mandibular third molar surgery. Methods: The prospective study was comprised 30 patients who presented for the removal of bilateral impacted mandibular third molar teeth. After extraction, the sockets were filled with PRF or without PRF in the study and control groups, respectively. Postoperative edema was measured with a flexible tape measure by calculating the distance between several facial landmarks on postoperative days two and seven. Postoperative pain was evaluated with a line-type visual analogue scale (VAS) and a verbal scale (VRS). SPSS version 20.0 was used for data analysis. Results: Both groups recorded significant improvement compared to the baseline levels in almost all of the outcome variables. There was no statistically significant difference between the study and control groups (p > 0.05). Conclusions: Using or not using PRF to reduce postoperative pain and edema in third molar surgery was equally successful. Trial registration: This study was retrospectively registered at the ISRCTN registry (ISRCTN16849867) on 6 March 2017. © 2017 The Author(s)

Techniques and modifications for TMJ arthrocentesis: A literature review

Objectives: To discuss advantages and disadvantages of TMJ arthrocentesis techniques, identifying modifications as reported in the literature. Methods: A PubMed web-based search was carried out, using the terms TMJ and arthrocentesis, to determine the scope of coverage in well-documented articles in English. Results: Among 237 articles, 12 distinct techniques were described for TMJ arthrocentesis in 12 articles. Among 12 techniques, 5 were classified as double puncture arthrocentesis (DPA) and 7 as single puncture arthrocentesis (SPA). In total, 17 well documented articles about SPA were found in literature. Discussion: Arthrocentesis of the temporomandibular joint (TMJ) was first described in 1991. To make the traditional procedure even less invasive, many arthrocentesis methods have been described. However, in 2015, TMJ arthrocentesis techniques were divided into two groups to limit the complexities surrounding the concepts related to TMJ arthrocentesis techniques. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group

Determination of Field Performance and Molecular Discrimination of Clementine Mandarin Selections

Clementine (Citrus clementina) is one of the most important mandarins with high yield and good fruit quality. Actually Clementine may be considered as a group instead of only one cultivar because of many Clementine clones exist in the world. Also it has been cultivated for a long time in Turkey, and therefore variations for agronomical traits are likely among cultivated Clementines due to bud mutations and hybridizations. The objectives of this study were to determine variations for some selected agronomical traits and genetic markers among 6 new Clementine clones ('A-21', 'A-67', 'A-68', 'A-82', 'A-90' and 'D-22') derived from selections. Tree growth, yield, fruit quality, and molecular discrimination of these clones were determined. After four years of evaluation, 'D-22' indicated the highest canopy volume. For yield per tree, the best clone was also 'D-22'. The highest fruit weight obtained from 'A-82'. Among the clones 'A-21' contained the lowest seed number and the highest total soluble solids/total acidity ratio. Molecular analysis, as assessed with 12 inter-simple sequence repeats (ISSR) primers, indicated that selections were separated with markers. Similarity values among the Clementine selections were between 0.97 and 1.00. According to our results low level of genetic diversity was determined among selections and it can be concluded that variations in orchards are abundant and mainly due to mutations

Effects of modic changes in lumbar spine on pain intensity, disability and quality of life

Aim: To assess the effects of Modic changes on pain intensity, disability and quality of life. Method: 121 patients were included. Pain intensity was assessed using The McGill Pain Questionnaire, level of disability was assessed using The Oswestry Disability Index and quality of life was assessed using The SF-36 Health Survey. Modic changes were classified into ‘Type0’(no Modic changes), ‘Type1’(Type1 and 1/2) and ‘Type2’(Type2, 2/3 and 3). Results: 76(62.8%) patients had Modic changes. Of these 23(30,3%) had ‘Type1’ and 53(69,7%) had ‘Type2’. In The McGill Pain Rating Index, patients with Modic changes had worse score than patiens without Modic changes(p=0,006), there was no significant difference between Type1 and Type2(p>0.05). Patients with Modic changes had higher level of disability in The Oswestry Disability Index scores, compared to those without Modic changes (p=0,000), there was no significant difference between Type1 and Type2 (p>0.05). Patients with Modic changes had worse score in The SF-36’s dimensions of Physical Functioning (p=0.000), Physical Role Functioning(p=0,000), Bodily Pain(p=0,008), Emotional Role Functioning (p=0.023) and Social Functioning(p=0,002), compared to those who had no Modic changes. In these dimensions, there was significant difference between Type1 and Type2 (p>0.05) except Social Functioning(p=0,030). Modic changes have a negative effect on pain and level of disability but there is no difference between Type1 and Type2. Conclusion: Modic changes have a negative effect on quality of life in terms of dimensions of Physical Functioning, Physical Role Functioning, Bodily Pain, Emotional Role Functioning and Social Functioning. But there is no difference between Type1 and Type2 except Social Functioning

Horizontal maxillary sinus septa: An uncommon entity

Introduction Maxillary sinus septas are barriers of cortical bone that arise from the floor or from the walls of sinus and may even divide the sinus into two or more cavities. Morphologically maxillary sinus septa are generally oriented in buccopalatinal orientation horizontal or sagittal orientation of the sinus septa is a rare condition. Presentation of Case This report presents two sinus lift case, in which observed septa in a horizontal orientation was presented. Both cases were fixed by an implant supported prosthethic restoration. Discussion Surgeons must know detailed knowledge about maxillary sinus anatomy for successful sinus augmentation. Computed tomography (CT) is useful for examining the maxillary sinus. Conclusion Horizontal-type sinus septa are rarely seen. Surgeons must be aware of septa types and orientations. © 2015 The Authors. Published by Elsevier Ltd. on behalf of Surgical Associates Ltd
