Root Canal Filling Process Enhancement in Simulated Dental Blocks Using a Novel Device

20 Dec 2016-pp 667-677
Abstract: Root Canal Treatment is performed to save infected tooth. The study has been done to enhance the filling of Gutta Percha (material) in biomechanically prepared dental blocks (DENTSPLY) using vibratory energy during compaction. Two groups of samples, each containing ten blocks was obturated. First group samples were obturated with conventional down-pack technique (Heat & Compaction) for varying frequency of vibration at the dental tip (10–100 Hz). Sample weights were recorded before & after filling. This was followed by obturation over the same blocks using new proposed method (heat, vibration & compaction) and the weights were recorded after vibration aid. The same experiment was performed for the second group (of 10 samples) for constant frequency (50 Hz) at the dental tip. A statistical test (Student-t test) for these groups showed 21% enhancement over the conventional method. The variation in the results in the two groups was found insignificant based on 1-way ANOVA.

Abstract: Use of Mouth Guards (MGs) can protect from such orofacial injuries in contact sports by reducing the impact force through its shock absorption capabilities. The objective of the current study is to organize relevant literature by other researchers following selection of suitable biomaterial for mouth guards. Orofacial injuries in contact sports (such as boxing, rugby, football, basketball, and karate, etc.) are common events. There are three different types of Mouth Guards available: Boil and bite, Stock, and Custom made. The Boil and bite are made by thermoplastic material and further heated in hot water and placing it in an athlete’s mouth by pressure application. The stock type has been found cheaper than the other two. The custom-made type is prepared on the imprints of the mouth of an individual patient. It has great benefits than two and provides greater comfort while speaking but slightly costlier. The MGs are available in different thicknesses according to the type of MGs and patient needs. Thickness carries an important role in fabricating MGs. Thickness affects comfort, breathing, speech, and shock absorption capabilities during activities. But there is still no specific thickness or material prescribed carrying good comfort and provides better protection from impact. It is still expected to conduct extensive impact studies on varieties of materials, combinations of available materials and also varieties of Biomaterials available for MGs to verify suitability being optimum one. EVA MGs, polycarbonate foam, polycarbonate-EVA Sandwich, polystyrene-polyolefin copolymer, new-generation polyolefin self-adapting MGs, Corflex have been seen to be the biomaterial choice for mouth guards.

Abstract: Aim To compare the percentage of gutta-percha-filled area (PGP) in simulated root canals when varying the penetration depth and function of the pluggers (heat versus heat plus vibration) using Endo Twinn. Methodology Sixty-four resin blocks with simulated 34–35° curved canals were randomly divided into two groups in order to obtain two canal shapes: group A with 0.8 taper and group B with 0.4 taper. The apical portion of each canal was prepared to a size 20 K-file. The canals were filled with gutta-percha in combination with a root canal sealer. In each group 16 canals were filled using the Endo Twinn heat function and 16 canals by means of both the heat and the vibration function. All samples were sectioned horizontally at three levels (1.25, 2.5 and 4.0 mm from the working length) and the PGP was measured. Data were analysed using anova test. Results At the 1.25 mm level PGP was significantly greater using the vibration function (P = 0.0329) and in 0.8 taper canals (P < 0.0001). At the 2.5 mm level the PGP was greater in the canals with 0.8 taper compared with a 0.4 taper with or without vibration (vibration, P = 0.0056; interaction taper-vibration, P = 0.0020). In 0.4 taper canals the PGP was greater when the vibration function was activated. At the 4 mm level in 0.8 taper canals there was no significant difference in PGP with or without the vibration (P = 0.6742). Conclusions 0.8 taper canals had significantly greater PGP than 0.4 taper canals. At the 1.25 mm level there was significantly greater PGP when the vibration function was activated.

Abstract: HYBROSONIC : The name derives from Heat + Sonic Vibration. The invention relates to Root Canal Obturating Device for fillling of Root Canal after removal of tooth pulp. Root canal treatment is the removal of tooth's pulp, a small thread like tissue in the centre of the tooth. Proper root canal filling should achieve three dimensional obturation of the root canal space to prevent micro organisms from entering and re-infecting the root canal system and to prevent tissue fluids from percolating back into the root canal system to provide a culture medium for any residual bacteria. It should seal all portals of exit to impede any sort of communication or exchange between the endodontium(within the tooth) and periodontium(outside the tooth). If the tooth is not sealed properly the root canal may leak and lead to failure of treatment. Conventional obturation techniques like cold lateral condensation technique and warm vertical condensation technique have limitations and are very technique sensitive hence a novel machine was developed which transforms gutta percha (root canal filling material) into alpha phase and using sonic vibrations the gutta percha is f orced to flow into lateral canals(accessory canals in horizontal planes), thus achieving 3-Dimensional fuild tight hermetic seal and thus preventing any chances of re-infection, and fulfilling one of the amin goals of endodontic treatment. Hence, an innovative, efficient, fast yet economical method to achieve perfect obturation thus, enhancing the prognosis of the tooth.
