Several articles have used cone beam computed tomography (CBCT) to study the morphology of the maxillary molars and to ascertain its ability to visualize the second mesiobuccal canal (MB2); however, its geometric location has not been examined in depth. The aim of this study was to describe in vivo the prevalence and location of the MB2 in the mesiobuccal root of the first maxillary molar (1MM) and the second maxillary molar (2MM) through CBCT imaging. Five hundred fifty CBCT images of the 1MM and 550 of the 2MM were analyzed. To detect the MB2 canal, the observation and measurements were done 1 mm apically to the pulpal floor to standardize the methodology. The geometric location of the central point of the MB2 canal (PMB2) was measured in relation to the central point of the mesiobuccal canal (PMB1) and in relation to the line projected between the PMB1 and the central point of the palatal canals (PP). The data were analyzed using descriptive statistics, with a value of P | 0.05 being statistically

TY - JOUR. T1 - Efficacy of irrigation with rotary instrumentation. AU - Walters, Matthew J.. AU - Baumgartner, John (Craig). AU - Marshall, J (Gordon). PY - 2002/12. Y1 - 2002/12. N2 - The purpose of this study was to evaluate the efficacy of a handpiece-mounted irrigation device and compare it to irrigation with a syringe and needle in the apical 5 mm of the root canal system. Twenty matched pairs of extracted teeth were used. The only variable within each matched pair was the method of irrigation. A syringe and needle were used in group A and the handpiece-mounted system in group B. Sections 1, 3, and 5 mm from the working length were examined microscopically, and images of the slides were digitized. The percentage of canal space occupied by pulpal and dentinal debris was calculated to be 6% ± 12.7% in group A, versus 3.8% ± 7% in group B (p = 0.264). The percentages at each level were as follows: 1 mm from the working length, 14.1% ± 19% for group A and 5% ± 7.5% for group B; 3 mm from ...

Direct access to the root canals in posterior teeth for endodontic treatment is most frequently facilitated by the straightening of the coronal parts of the root canals, having as a consequence the relocation of the canal orifices on the map of the floor of the pulp chamber (Christie & Thompson, 1994). This procedure intentionally moves the coronal aspect of a canal away from the center of the chamber, while simultaneously removing internal dentin from the pulp chamber walls. The aim of this study was to evaluate the displacement resulting from the relocation of root canal orifices during the initial phase of rotary root canal treatment in molars using the dental operating microscope (DOM) and digital image processing ...

In carrying out the prohibition of the sale, manufacture for sale, and all that relates to sale, the next question that arises is whether the scope of the prohibition should be limited to small units, like the town and the county, or should extend to the large units making it state-wide and nation-wide. It is good to have a town dry rather than wet. It is better to have a county dry rather than wet; but if prohibition is by the small unit, then wet towns and wet counties will be found near by, and the virus there generated will pass over continuously and reinfect the dry town and the dry county. It is a good thing to cut out one root of a cancer, it is a better thing to cut out another root, but as long as a single root remains it will generate the virus and inject it into the circulation and reinfect the whole system. As long as there is one state in the Union that is wet it will be the base of operations and source of supply for the national liquor trust, from which, through interstate ...

Taurodontism is a dental anomaly characterized by enlarged pulp chamber which may reach the proximity of root apex, apical displacement of the pulpal floor, and no constriction at the level of the cement-enamel junction. Despite the clinical challenges in endodontic therapy, taurodontism has received little attention from clinicians. In performing root canal treatment on such teeth, one should appreciate the complexity of the root canal system, canal obliteration and configuration, and the potential for additional root canal systems. This case report presents the taurodontism in tooth number 26 and 36. A conventional root canal treatment was carried out for these pulpally involved teeth.
The principal etiology in pulpal and periapical disease is the presence of bacteria in the root canal system (Happasalo et al. 2003). Anatomically complex root canal systems that contain lateral canal ramifications, isthmuses, cul-de-sacs, and other irregularities can impede the elimination of debris and bacteria from the root canal system (Wu et al. 2006). In addition, bacteria can penetrate into dentinal tubules and persist after the completion of the endodontic therapy resulting in refractory infections years later (Vieira et al. 2012). Irrigation is the only way to impact those areas of the root canal system that cannot be cleaned by mechanical instrumentation (Happasalo et al. 2010).. The effectiveness and biocompatibility of irrigating solutions is dependent on a multiplicity of factors such as microorganism susceptibility, penetration of the solution to the infected site, concentration of the solution being used, and the toxicity to host cells (Mohammadi 2008). Sodium hypochlorite has ...
Objective: This study was conducted to determine the most prevalent root canal configuration and the incidence of a second mesio-buccal (MB2) canal in maxillary first molar root in an Indian sub-population of Pune, Maharashtra, India by reviewing cone-beam computed tomographic (CBCT) images. Methods: Patients who had undergone CBCT scanning for various treatment modalities were retrospectively viewed for the presence of second MB2 canal in the permanent maxillary first molar. Scanning was performed at Peraden & Elite CBCT, Pune, Maharashtra, India. Each tooth was assessed in 1 mm axial and 0.5 mm sagittal sections, to evaluate the presence of a MB2 canal. The images had been evaluated by a maxillofacial radiologist. Results: In total of 117 teeth examined, MB-2 was present in 79 teeth. The prevalence of MB-2 in maxillary first molar was found to be 67.5% in an Indian subpopulation. As far as root canal morphology is concerned, Vertucci Type I was the most common type. Conclusion: Knowing the ...
In the center of each living human tooth there is naturally a space which contains the nerves or "pulp" of that tooth. This space is known as the root canal and its vitality or life is not crucial to that tooths function in the mouth once it is erupted.. In some cases it may be necessary to remove the nerve from one of your teeth to get you out of pain and save that tooth from being pulled. This procedure is known as a "Root Canal" or Root Canal Therapy.. If you are feeling tooth pain when you drink cold liquids or eat/chew something very cold you likely have inflamed tissue in your root canal. This inflammation and increased sensitivity can be caused by oral bacteria and their byproducts entering your root canal space through a cavity or underneath a leaky restoration. Depending on the character and duration of your pain as well as the analysis of radiographic and clinical tests we can advise you as to rather it is possible to fix your tooth with a simple filling or if the decay will possibly ...

Thorough understanding of the anatomic and internal morphology of a root canal system is absolutely essential for the success of endodontic treatment. Since permanent maxillary first molars have shown variation in internal anatomy, morphology, this tooth has been reviewed extensively. Presence of two canals in a two-rooted maxillary first molar has rarely been reported in studies describing tooth and root canal anatomies. In this report, three cases are presented, which involve the root canal treatment of maxillary first molars with fusion of the two buccal roots ...
My No 3 had a root canal and crown. There was a 3/16 Inch circle between the three roots on the X-ray, and a dark line, about 1/16 Inch long on the x-ray. There was another small circle at the tip of one of the roots of #3. I could feel sensitivity in my upper right jaw, when taking a steep step, or changing my head position abruptly. I slap the back of my head lightly, to guage my progress. #3 is the third from the back, upper jaw, Right side. Extraction was recommended. So I had the tooth extracted, and there was a 3/16 Inch diameter bag of a substance, between the three roots, the Oral ...

In anatomy the apical foramen is the opening at the apex of the root of a tooth, through which the nerve and blood vessels that supply the dental pulp pass. Thus it represents the junction of the pulp and the periodontal tissue. The average size of the orifice is 0.3 to 0.4 mm in diameter. There can be two or more foramina separated by a portion of dentin and cementum or by cementum only. If more than one foramen is present on each root, the largest one is designated as the apical foramen and the rest are considered accessory foramina. It is a point of interest in endodontics, as it is considered necessary to thoroughly chemomechanically debride the pulp space to remove all necrotic tissue and minimise bacterial load in the pulp space. Ideally this debridement would terminate exactly at the apical foramen. In reality determining the exact position of the apical foramen is problematic, requiring radiography and/or use of an electronic apex locator to produce a refined estimate. A tooth may have ...

Also known as a root canal, endodontic treatment becomes necessary when the dental pulp is permanently injured. Tooth decay, repeated fillings, physical trauma, or periodontal disease are possible causes. Treatment involves removing the pulp, then cleaning, shaping, and sealing the root canal spaces. The tooth will remain alive because it is nourished by the adjacent tissues of the gums and surrounding bone. After completion of your root canal treatment, you should return to your family dentist for the permanent restoration of the tooth ...
photo provided by aae.org. Left untreated, a dental abscess (infection) can be a huge problem. An abscess is essentially a pocket of pus that is formed as a result of a bacterial infection in the mouth. This infection, left untreated, can travel to your jaw, neck, brain or cause sepsis, a life-threating infection throughout the body. If the tooth is unable to be saved with a root canal, it must be removed in order to completely remove the infection. Antibiotics will only calm the tooth for a short period and will not cure an abscessed tooth.. What are the signs and symptoms that root canal therapy is needed?. One of the most obvious signs that a root canal is needed is severe pain. It is usually triggered by chewing or the application of pressure. If a tooth has prolonged sensitivity to either heat or cold, lingering after the temperature is removed from the tooth, it also indicates damage to the nerve. If a tooth becomes discolored over time, a bump or small pimple appears close to the root of ...

The animation on the right depicts the process of a tooth requiring a root canal from an untreated cavity to the subsequent steps that occur to restore the tooth.. The first few images show the tooth with a cavity. If the decay was removed at this point, the tooth would merely need a filling. As the cavity progresses, it breaks through the enamel, which is the hard outer layer of tooth, and it enters the dentin, which is the layer of tooth beneath the enamel. The dentin is much softer and once the decay enters this layer, it spreads much faster as it progresses its way to the pulp.. Once the decay enters the pulp, you now have bacteria from your mouth that invade the root canal system and cause destruction of the surrounding bone, which can be a very serious situation and can cause both serious pain throbbing within the tooth. At this point, you either need to have a root canal or have the tooth extracted. It is also possible for the infection to cause death due to a condition called bacterial ...
The aim of root canal treatment is to get rid of the damaged pulp and the bacteria that are causing the infection. It involves removing inflamed or dead nerves and blood vessels from the centre of your tooth. This is done by drilling a hole through the top of your tooth to the root canal and removing the dead tissue. The empty root canal system is then cleaned, filled and a permanent seal put over the top of your tooth. The procedure may be carried out over one or two visits.

From Saturday through Sunday, I traveled. Mom and I went down to San Diego and crossed the border into Tijuana on Saturday. The reason for this was because I had some dental work to be done. We have a family friend who is a dentist and when she heard how much they were charging me (out of pocket) Stateside, she told me to go down and shed take care of it for me. It turns out I didnt even need one of the root canals the dentists here were pushing... and, really, there was a lot that I thought I needed but didnt actually need. In fact, I didnt even get a single root canal done; she just repaired the chipped molar and did other things that dentists here didnt want to do but were necessary because of how fragile my health has been. (Those were her own words; they were putting me at a greater risk for refusing to fill a big cavity and the chipped molar.) It took us nearly 2 hours just to cross the border (by car) back into the States on Saturday night and then we slept for a couple of hours ...

This treatment consists in a set of varied possibilities aimed at restoring the normality of dental tissues or at least keeping the tough structure (tooth) in its alveolus, without the presence of inflammation or infection. The treatment of the canal is based on the removal of all tissue, alive or not, from the pulp chamber and the root canal system present in the roots such as their cleaning and widening of these channels for later sealing through a proper filling ...
The monocots both seemed to have a single root that came out of the side of the seed. Then a stem comes out, connecting the roots and the seed. The seed and the stem start to rise out of the ground and the brown sheds off. Leaves start to sprout from the seed. The leaves soot up, straightening out and the seed, split into two, shrivels up and hangs limply to either side of the plant. The dicot had multiple roots that came out of the bottom of the seed. Then the roots grow longer and some stems grow out of the top. Then the stems start to look like leaves ...
