Introduction: The fear of dentists is one of the major concerns why pediatric patients avoid dentists and thereby compromising their oral hygiene status. Injection of local anesthesia is considered to be the most dreaded procedures and dentists all over the world have adopted different techniques to allay the fear, pain and anxiety of the patients. Material and Methods: 54 children aged between 6-13 years were included in the study. A simple randomization was done and the children were divided into three groups. Application of topical anesthesia gel at the site of administration of local anesthesia, pre-cooling the anesthetic site with ice prior to the administration of local anesthesia, vibratory stimulus adjacent to the site of administration of local anesthesia using a powered toothbrush were the groups from 1-3 respectively. The pain perception during the administration of infiltration anesthesia was assessed using Wong-Baker Faces Pain Rating Scale. The statistical analysis was performed using SPSS software. Results: The greatest pain reduction was observed in the vibrations group with mean pain score 1.33 followed by pre cooling group with mean pain score 2.44 then topical anesthesia gel with mean score of 4.67. Mann-Whitney test showed that vibrations was statistical significant when compared with topical anesthesia and pre cooling before local anesthesia (P<0.003). Conclusions: Use of vibrations using powered tooth brush adjacent to the site of injection during Local Anesthesia (LA) is an easy, reliable and cost effective technique and was found to reduce discomfort and facilitate the management of pediatric patients.

Stability of miniscrews or Temporary Anchorage Devices (TADs) is an essential factor for successful application in orthodontics. Miniscrews removal torque can be used as an indicator of miniscrews stability. The objective of this work was to compare removal torque between self-drilling tapered mini-screws and cylindrical miniscrews. Materials and Methods: Two groups of TADs were inserted in the maxillae of orthodontic patients to provide stationary anchorage for front teeth retraction. Group 1: 20 tapered self-drilling miniscrews, Group 2: 20 cylindrical self-drilling miniscrew. Split mouth technique was used. All of the TADs were inserted parallel to the occlusal plane, between roots of the 2nd maxillary premolar and 1st maxillary molar. The TADs were immediately loaded with constant and continuous load using 8 mm long heavy short Nickel Titanium coil spring. The coil spring was stretched between the heads of the two types of TADs and crimpable hooks that fixed on arch wire just distal to the anterior six maxillary teeth. After complete retraction of the anterior maxillary teeth, TADs were removed using torque adjustable screw-removal. At the moment of movement of the TAD the torque was recorded in Newton Centimeter (Ncm). Results: Mann Whitney U Test resulted in a significant difference between the two groups, indicating that cylindrical TADs had significantly higher removal torque than tapered TADs (means were 3.20 Ncm ± 0.20 and 2.70 Ncm ± 0.10 respectively). Conclusion: Physical properties have a considerable influence on the stability of the TADs. Cylindrical TADs are showed more mechanical interlock into the bone.

The injection molding process of thermoplastic nylon produces nylon residues in the form of sprue. Nylon residues are non-biodegradable which causes serious ecological problems, hence recycling becomes a necessity. However, recycled nylon is subjected to thermal, oxidative, and mechanical degradation during process which may decrease the mechanical properties of recycled nylon. In order to overcome the decreased mechanical properties of recycled nylon, modification by combining recycled nylon with virgin nylon is considered. Aim: This study aimed to determine the effect of adding virgin nylon into recycled nylon on the modulus of elasticity and compressive yield strength. Settings and Design: Experimental laboratory research. Methods and Materials: A total of 45 samples were used. Samples were divided into 3 groups which include 100% virgin nylon as control (A), 100% recycled nylon (B) and combination of 60% virgin nylon with 40% recycled nylon (C). The samples were tested using Universal Testing Machine (Tensilon RTF, Japan) with three point bending test and compression test with the speed of 5mm/min with ultimate load. Statistical analysis used: The obtained results were analyzed using Univarian test, One-way ANOVA test and Turkey’s Honestly Significant Different test. Result: There was statistical significance in adding virgin nylon into recycled nylon on its mechanical properties, namely modulus of elasticity and compressive yield strength (p<0.05). Conclusion: The combination of 60% virgin nylon with 40% recycled nylon has better elastic modulus and compressive yield strength values compared to 100% recycled nylon.

This study was carried out to study a restorative technique of 2 mm thickness of composite resin filling material that bonded, by adhesive (4-META), to MOD cavities (Mesial, Occlusal and Distal surfaces of a tooth) partially filled with amalgam filling materials in upper premolars on the fracture resistance when compared to a sound tooth. Forty freshly sound extracted upper premolars were divided into four groups: the first group of ten sound premolars is subjected to fracture resistance test, the second group of ten premolars with a MOD of half intercuspal distance cavities, which was prepared with long bevel at the cavosurface angle and the teeth were filled with composite resin following incremental technique. The third group of ten teeth were prepared with a box form and butt joint of the same MOD cavities dimension and filled with non-gamma II amalgam. The fourth group of ten premolars with the same MOD cavities dimension are filled with amalgam, a 2 mm thickness of amalgam was removed of the occlusal surface after 24 hours, extended proximally mesially and distally, etch of the exposed enamel, dentin and amalgam was performed, and 4-META adhesive was applied to amalgam and exposed dentin and enamel followed by posterior composite bonded to tooth and amalgam, and cured with light for 40 seconds. The teeth of all groups were tested for fracture resistance. The group I showed the highest resistance to fracture followed by group IV followed by group II and lastly, group III. This study concluded that the use of combined bonded amalgam-composite and tooth structure provided the best technique for filling than cavity only filled with composite or amalgam.

Ameloblastoma is a common odontogenic tumor with the potential of local invasion and recurrences. Moreover, it has a variable presentation and many challenges surrounding the management of the condition [1]. From public health perspectives through to molecular aetiopathogenesis it paints the portrait of heterogeneity and complexity [2-4]. For example, gender and age distribution, presenting complaints, the clinical record keeping scenarios in developing countries compared to the developed countries, the aggressive potential for local invasion, possibility for malignant transformation etc. Moreover, choosing the optimal mode of management (radical vs conservative surgery) poses a dilemma to the clinician. Findings of retrospective studies on de-identified case notes retrieved for varying follow-up periods provides the major source of scientific evidence on management of ameloblastoma.

Microstomia is a condition with abnormally small oral aperture which is associated with compromised aesthetics and function of stomatognathic system. In young children, the leading cause of microstomia is oral electrical or chemical burns. Management of microstomia requires multidisciplinary approach including surgery, physiotherapy and appliance therapy. Appliance therapy in form of microstomia prevention appliance plays a pivotal role in prevention of contraction of tissue during healing. Numerous appliances have been described in literature to prevent microstomia. However, decision to use a particular appliance require meticulous planning considering the efficacy and effectiveness of the appliances and various patient factors like age, dentition status and compliance. This paper presents an unusual clinical condition where a unique customized microstomia prevention appliance therapy was instituted to prevent microstomia in 2 year old female patient following lip surgery. This appliance was constructed easily and inexpensively, could be adjusted so that it was almost painlessly inserted, and was progressively adapted. It was convenient for use in young child with minimal compliance offering improved mouth opening and consequently functional outcomes.

Background: Intraoral digital scanning could offer a win-win clinical pathway for both doctor and patient, but many factors can affect its accuracy. This study was designed to investigate the effect of the scanning number on the precision of digital impression in different gypsum models. Materials and methods: 30 standard gypsum models were divided into group A, B, C, D and E. Each group was scanned with 400 and 1000 pictures by Trios. Then Using the three-dimensional preview function to compare the fitted images and to measure the distance between markers: the buccal-lingual thickness of maxillary central incisors, the length from the medial to the distal of buccal cusps of maxillary second molars, the crown width of mandibular central incisors, the buccal-lingual thickness of maxillary central incisors requiring a veneer, and the buccal-lingual width of the inlay of the mandibular first molar. Results: The scanning time of 1000 scanning number groups were significantly prolonged and the efficiency of 3D reconstruction was significantly reduced. But obvious image stitching distortion could be observed in these groups compared with 400 scanning number groups. Whats more, the compare of measured values in each 400 and 1000 scanning number group was all statistically significant. Conclusion: The data splicing caused by the excessive scanning number may influence the digital impression accuracy. Trios scans 400 pictures was with higher scanning accuracy than scanning 1000 pictures.

Neural Arterial Gingival Simplex is a common systemic disease linked to an invasive periodontal pathogen, Porphyromonas gingivalis as the key initiator. Instead of considering separate pathologic conditions as separate diseases, the health community should view this disease as a single entity, to diagnose and treat accordingly. We discuss the evidence for this hypothesis and the need for definitive research. A strategy to maintain a healthy, resilient microbiome with adjunctive support by probiotics and polyols is warranted. Newer diagnostic and monitoring technologies along with many possible therapeutic agents and protocols are readily available to prevent and treat Neural Arterial Gingival Simplex.

Introduction: Presence of foreign body in the root canal system is a troublesome situation as they prevent the access to thorough root canal cleaning and shaping procedure apical to their level. They might also irritate the periapex when they protrude out of the root apex. This affects final outcome of endodontic therapy. Hence an attempt to bypass or retrieval of the foreign body should be made before leaving and obturating till the level of their presence or proceeding to surgery. The procedure for removal will vary depending on the nature of the foreign body and its position within the canal. Many different devices and techniques have been developed to retrieve foreign bodies from the root canal system, but none of them can consistently remove them from the canals. Case Presentation: Three cases requiring removal of foreign bodies from the different positions in the canals are presented. These cases present the conservative management of an inadvertently lodged foreign body in the root canal system during a routine dental procedure and describe the management strategies for their retrieval. Conclusion: Provided one has good patient cooperation, management of the situation can be quite straight forward if the appropriate diagnostic and treatment tools are utilized.
