Maxillary Incisors

ABSTRACT Restoration of grossly mutilated primary maxillary incisors affected by early childhood caries has been a challenging task for the pediatric dentist due to the little amount of tooth structure available for bonding and behavioral problems of the children. A variety of treatment options ranging from extraction followed by prosthesis to the usage of intracanal pins and fiber posts have been reported in the past. The present case report depicts one such a case wherein biological restorations were used as post and core to restore the mutilated primary maxillary incisors in a 4-year-old child treated under general anesthesia.

Post And Core

Endodontic posts are necessary to provide adequate retention and support when no sufficient remaining structure is available to retain the core. There are different materials and techniques to construct post-and-core, but there is no consensus about which one promotes better stress distribution on the remaining tooth structure. This study aimed to quantify and evaluate the distribution of stress in the root produced by customized glass fiber posts compared to different endodontic posts. Twenty-five simulated roots from photoelastic resin were made and divided into 5 groups: CPC, cast post-and-core; SP, screw post; CF, carbon fiber post; GF, glass fiber post; and CGF, customized glass fiber post. After cementing CPC and SP posts with zinc phosphate cement, and CF, GF and CGF posts with resin cement, resin cores were made for groups 2-5. Specimens were evaluated with vertical or 45° oblique loading. To analyze the fringes, the root was divided into 6 parts: palatal cervical, palatal middle, palatal apical, vestibular cervical, vestibular middle, and vestibular apical. The formed fringes were photographed and quantified. Data were recorded and subjected to two-way ANOVA and Tukey's test (5%). SP (1.95±0.60) showed higher stress (p<0.05) compared to the others (CPC-0.52±0.74; CF-0.50±0.75, GF-0.23±0.48 and CGF-0.45±0.83). All posts showed high stress in apical third (CPC-1.40±0.65; SP-2.30±0.44, CF-1.80±0.45, GF-1.20±0.45, CGF-1.70±1.03) Low stress was found in cervical third (CPC-0.20±0.45; CF-0.00±0.00, GF-0.00±0.00, CGF-0.00±0.00), except by SP (1.90±0.65), which showed statistical difference (p<0.05). Customized post showed high stress concentration at the root and conventional glass fiber posts showed more favorable biomechanical behavior.

Introduction: Endodontically Treated Teeth (ETT) are most likely to get fractured, if it is left unrestored compared with the vital teeth due to the loss of tooth structure and reduced modulus of elasticity. Aim: To gain insight into the rationale for choice of endodontic posts and the different endodontic post systems currently used by dental practitioners in western region of Saudi Arabia. Materials and Methods: For this survey-based study, a questionnaire was designed consisting of eight questions to assess the details of why, when and how general practitioners restore ETT and to determine contemporary use of endodontic post from 1st of November 2018 till the end of January 2019. This questionnaire was sent online to 250 private dental practitioners in western region of Saudi Arabia, out of which 202 participants responded. Data was entered in the excel sheet. Descriptive statistics like frequency and proportion was calculated for qualitative data. Results: This study included 202 participants with the mean age group of 25-50 years, out of which 108 (53.4%) male participants and 94 (46.5%) female participants. 120 (59%) of the study sample were general practitioners and 82 (41%) of them were specialists. A total of 60 (29.70) of the study sample were into general practice, reported restoring ETT with post and core followed by the crown, whereas, 30 (14.85%) of them did the crown without post, 15 (7.42%) of them completed restoration with composite and 15 (7.42%) of them did build-up with post and core. An 82 (40.59%) of the study sample who were specialists, reported restoring ETT with post and core build-up and then proceed with crowns. An 80 (39.60%) of the study sample were into general practice, reported using prefabricated fiber post whereas, 23 (11.38%) of them using cast post and 17(8.41%) of them using prefabricated metal posts. 72 (35.64%) of the study sample were specialists reported using prefabricated fiber posts and 10 (4.95%) of them used cast metal post. Conclusion: Based on the results of the study, it can be concluded that majority of the participants practiced reinforcement of ETT by using fiber posts with resin cements followed by crowns.

Coronal fractures of the anterior teeth arising after endodontic treatment are sequelae of dental trauma. Endodontically treated teeth presents a higher risk of biomechanical failure than vital teeth. Posts are needed for restoring teeth with insufficient coronal tooth structure to retain a core for definitive restoration. Fiber posts are more easily and safely removed "by hollowing them out from the inside”. This present case report depicts a 23 year old male patient with fracture of tooth number 21 which had undergone an RCT 8-10 months ago and was restored using fiber post.

Glass Fiber Posts

BACKGROUND Endodontically treated teeth are usually associated with insufficient coronal and radicular tooth structure and hence, are restored with both cast metal and fiber posts. However, there are limitations in both treatment options. Glass fiber posts have known to show better performance than cast metal posts due to similarity in elastic modulus with dentin. The purpose of this study was to compare and evaluate the performance of glass fiber and cast metal posts in endodontically treated teeth that required intraradicular retention. METHODS 40 endodontically treated teeth were selected in patients and divided into two groups, glass fiber, and cast metal respectively. The participants were randomly allocated to both groups by using their registration number with an allocation ratio of 1:1. Participants were recalled at 3 and 6 months after cementation (baseline) for follow up. Radiographs were taken and evaluation was done according to FDI criteria. The intergroup comparison for the difference of mean scores between the two independent groups was done using the unpaired / independent t test. RESULTS Of the 40 endodontically treated teeth, 20 were restored with fiber posts and 20 were restored with cast metal posts. In total, 8 incisors, 6 canines, 21 premolars, and 5 molar teeth were included. The 6-month clinical survival of fiber posts was 100 % while that of cast metal posts was 95 %. The results were found to be nonsignificant (P = 0.159, 0.231, 0.805 at baseline, 3 months, and 6 months respectively). CONCLUSIONS The overall performance of the glass fiber posts was better than that of cast metal posts within the 6 months’ study period. However, no statistically significant differences were seen. Hence, in short follow up periods, both showed similar results and performed equally well. KEY WORDS Glass Fiber Posts Cast Metal Post Post and Core Technique Endodontically Treated Teeth

Purpose: To examine current decision-making preferences of Jordanian dentists when Restoring Root Filled Teeth (RFT). Materials and Methods: 834 Jordanian general dentists, prosthodontists and endodontists were invited to participate in a validated online survey with a 62% participation rate. Respondents were invited to answer 24 questions about their preferences for techniques and materials they use to restore RFT. The questions aimed at exploring restorative strategies commonly employed by Jordanian dentists when managing root filled teeth with extensive loss of tooth structure. Results: A minority of dentists consider direct resin restoration as the sole restoration for RFT with extensive loss of tooth structure. Full coverage metal-ceramic and all-ceramic crowns are more popular than endocrowns when restoring RFT with indirect restoration. Fiber posts are the most popular type of posts, followed by prefabricated metal posts. Glass ionomer is the most preferred cement for luting metal posts, while conventional dual resin cement with separate etch and rinse bonding strategy is the most employed when bonding fiber posts. The majority of dentists tend not to pretreat fiber posts. Loss of post/core retention or fracture of coronal tooth structure are the two most common reasons observed by dentists when RFT fail. Conclusion: Use of post and core is still preferred over more conservative approaches when restoring RFT with extensive loss of coronal tooth structure. Longevity of restorations can be enhanced by training practicing dentists on evidence-based adhesive strategies.

Endovenous Treatment

SummaryOver the past ten years endoveous treatment options for varicose veins have evovled considerably, offering clinicians a multitude of options to meet the needs of their patients. The endothermal ablation procedures have moved to the forefront as the choice modality for treating truncal reflux. Both radiofrequency ablation and endovenous laser ablation are widely accepted and interchangeable, showing comparable efficacy and safety. Although numerous endovenous laser wavelengths exist, the data indicates that the differences do not affect the efficacy or postoperative recovery of the procedure. The endovenous laser innovation that has shown early evidence of improved patient outcome is the jacket-tip fiber. The versatility of sclerotherapy makes it a critical component in the endovenous treatment of varicosities. Although not approved by the Food and Drug Administration (USA), the use of a foamed sclerosing agent is the fastest growing segment of sclerotherapy and an important treatment modality in the future of varicose vein treatment. Cutaneous lasers and intense pulse light devices contribute a crucial element, enabling clinicians to treat minute veins that may be impossible to treat with other therapies.

Psychiatric Problems

Anxiety disorders are among the most prevalent and most functionally impairing psychiatric problems experienced by the population. Both pharmacological and psychological evidencebased treatments exist for a number of specific disorders, but may fail to fully relieve symptoms, pointing to the need for additional treatment options. Often considered to be part of the “third wave” of cognitive-behavioral therapies, treatments incorporating mindfulness have emerged in the past two decades as increasingly popular with clinicians and frequently sought out by consumers. The present article reviews the extant literature regarding the efficacy and effectiveness of mindfulnessbased treatments for anxiety, worry, and related problems. Although they have not attained the solid empirical status of CBT or certain pharmacological treatments, the extant research shows mindfulness- based interventions appear to be a promising and useful treatment for people suffering from anxiety and worry. Further work should be done, levels 3-5 of the NIH stage model to determine whether or not they should be further implemented.

Dural Arteriovenous Fistulas

Abstract Dural arteriovenous fistulas are abnormal connections of dural arteries to dural veins or venous sinuses originating from within the dural leaflets. They are usually located near or within the wall of a dural venous sinus that is frequently obstructed or stenosed. The dural fistula sac is contained within the dural leaflets, and drainage can be via a dural sinus or retrograde through cortical veins (leptomeningeal drainage). Dural arteriovenous fistulas can occur at any dural sinus but are found most frequently at the cavernous or transverse sinus. Leptomeningeal venous drainage can lead to venous hypertension and intracranial hemorrhage. The various treatment options include transarterial and transvenous embolization, stereotactic radiosurgery, and open surgery. Although many of the advances in dural arteriovenous fistula treatment have occurred in the endovascular arena, open microsurgical advances in the past decade have primarily been in the tools available to the surgeon. Improvements in microsurgical and skull base approaches have allowed surgeons to approach and obliterate fistulas with little or no retraction of the brain. Image-guided systems have also allowed better localization and more efficient approaches. A better understanding of the need to simply obliterate the venous drainage at the site of the fistula has eliminated the riskier resections of the past. Finally, the use of intraoperative angiography or indocyanine green videoangiography confirms the complete disconnection of fistula while the patient is still on the operating room table, preventing reoperation for residual fistulas.
