Canines: Upper: Root Canal Anatomy: • It’ similar to that of maxillary incisors, with one major difference that it is wider labiolingually than mesiodistally. • Absence of pulp horns, mesial or distal. • Longest tooth in the oral cavity. • Mostly curved distally. • Pulp chamber outline is oval at CEJ and remains so throughtout the root until it reaches the apical third of the root. • Can be one or two canal, but mostly one. • Diameter of Canal at CDJ:298 µm. Lower; Root Canal Anatomy: • Similar to that of maxillary canine with the exception that its dimensions are relatively smaller. • Root canal outlines are more narrower mesiodistally. • It has: one root and two merged canals in 20% of cases.one by one in 70% of the cases, one root 2 distinct …show more content…
Shift bur to an angle parallel to long axis of canine, and keep penetrating until relief is felt, indicating penetration into pulp chamber. 6. Using the tip of the bur the chamber roof is identified by a catching sensation, the chamber is then removed, and further access inside the tooth is established. 7. Remove lingual shoulder to improve visibility. 8. Detect funnel out using gates glidden and endo probe 9. Repeat until orifices are visibile. Orifices are then flared. 1st Premolars: Upper: • Configurations: With one root: Can be 2 distinct canals (buccal and lingual) in 16% of cases. 12% of cases are 2 canals that merge at the end, another 10% where they merge in the middle. With two roots(buccal and palatal), 60%. 3 roots(distobuccal, mesiobuccal, and palatal), 3%. • There is a developmental depression on the lingual aspect in the buccal root. • Pulp chamber is wider buccolingually compared to mesiodistally. • There are buccal and palatal pulp horns in buccolingual point of view, with the buccal being larger in size. • The palatal orifice and canal are larger than the buccal ones. Lower: • Configurations: 70% 1 canal in 1 root, 25% 2 canals, 5% two roots. • Two pulp horns are present, small lingual one, large buccal …show more content…
• Depth of penetration is measured on an X-ray. Crowned/Heavily Repaired Teeth: Differences: • Removal of restoration due to the complication it brings if it were to remain(poor visibility, unclear x-rays, and such.) • Much consideration must be given to the alteration in the angulations and crown to root ration the heavy restoration caused. • If the crown were to stay then access cavity is done through it using newly bought carbice burs. Calcified Canals: Differences: • Locating the canals is the most difficult part, and thus transillumination carefule studying of morphology is the only way to find canals. • Calcified material is removed is removed down the root. Crowded Teeth: Differences: • To achieve straight line connection, buccal access may be utilized. • Like heavly restored teeth there is altered angulation and crown to root ration. • Treatment of such teeth needs constant radiographs after every step. • Outline is done without a rubber dam and the bur is parallel to long axis of
Crown Lengthening: You might need crown lengthening if you need a restoration or crown on a tooth. The problem is a result of the edge of your restoration being too close to the bone. The crown lengthening treatment gives you access to the restoration once again. This procedure basically creates a new tooth-to-gum relationship.

Epiphysis, is spherical in shape and is located at both the distal and proximal end of a long bone. It consists of an irregular latticework of needle-like threads of bone called trabeculae. Therefore, the spongy bone in the epiphyses help to withstand compressive forces. It passes on strength to a bone by adding minimum weight. The trabeculae also helps to develop the weight of the body out of the bony collar of the diaphysis.
All primates have essentially the same kinds of specialized mammalian teeth adapted to eating a wide variety of foods. Beginning at the front, each quadrant of the mouth has 2 incisors, 1 canine, and varying numbers of premolars and molars. The incisors are used like scissors for nipping off pieces of food. The pointed canines are for piercing and tearing. The premolars and molars, with their cusps, are used to grind and smash food. In platyrrhine species, there are 3 premolars and 2 or 3 molars. This results in a dental formula of 2.1.3.2 or 2.1.3.3. In contrast, all of the catarrhines have 2 premolars and 3 molars, making a dental formula of 2.1.2.3. The chimpanzee shown below is an Old World anthropoid species and, therefore, has a catarrhine dental formula.
It’s an accessory cusp usually located on the lingual surface of permanent or deciduous incisors.
This treatment entails your dentist scraping off some tooth enamel and placing a veneer or a type of bonding compound on the tooth. Laser or drills may be used for shaping and sculping the sides of both the existing tooth, as well as the new tooth. As a result, you have a beautiful smile. This procedure is not as expensive as other treatments done for correcting crooked
The root canal is a procedure in which and endodontist or dentist will perform to remove an infection from the pulp of the tooth canal. There are many indications to show that the patient will need this work completed such as pain, tenderness and sensitivity to warm and cold tempetures. When the endodontist is doing the procedure he will use many different tools such as endodontic explorers, files, peso reamers and gutter purcha. Once complete the patient will be a little sore but the initial pain will be gone.
This may be required in cases when the conventional root canal treatment is unable to save the tooth. It is a minor surgical procedure that involves the removal of the very tip of the tooth after which the gap is sealed. An apicoectomy also enables the endodontist to remove any infection or dead debris at the tip of the root. Once the canal is cleaned up and sealed, the risk of infection is very low. In some cases, the endodontist may use bone grafts or other implant techniques to assist with bone growth, especially in cases where the infection has left a big gap. In most cases, the tooth will be salvaged and normal function is
As part of Odontology, overview of the human dentition will be discussed. Important points that will be discussed will be as follows: four types of teeth in the human mouth: incisors, canines, premolars, and molars. Normal humans have two sets of teeth: deciduous (also called baby or milk teeth) and permanent. Similar to studying bones, cardinal directions are used when examining and describing teeth.
The bilabial nasal /m/ is produced by a contact between the two lips(i.e. lips are active articulators that come together to produce /m/ as in /madrash/ “ While the alveolar nasal /n/ is produced by the touching of the tip of the tongue with the alveolar ridge (i.e. , the active articulator is the tongue which moves towards the passive articulator which is the alveolar ridge to produce /n/ as in /nacm/ “soft”". " Versteegh et al (1983: 51) add that Sibawayh describes another place of articulation of nasal sounds besides the lips (bilabial) of /m/ sound and the tip of the tongue and alveolar ridge (alveolar) of /n/ sound, the place of homorganic “n” which is a nasal. This nasal noon /n/ is termed as “ Al-noon kaufee-ya” as in "Anka” from there” " " whose place of articulation is the nostrils only. It is more nasal than the letter (n) in the word “think” (Lunsden, 1813: 25).
