The pulpal wall is the internal wall that is perpendicular to the long axis of the tooth and occlusal of the pulp.

What is Pulpal tissue?

Introduction. The pulp is a mass of connective tissue that resides within the center of the tooth, directly beneath the layer of dentin. Referred to as part of the “dentin-pulp” complex, and also known as the endodontium, these two tissues are closely interrelated and dependent on each other’s development and survival.

What is the pulp chamber of a tooth?

Your pulp chamber is the hollowed-out space in the body or crown of your tooth, and your root canal is the section that extends down the root.

What is sub Pulpal wall?

Sub-pulpal wall: When the pulp is removed the pulpal wall disappears and the base of the pulp chamber becomes the sub pulpal wall.

What is Pulpal depth?

10 • Proper depth of the initial entry cut is 1.5-2mm.The pulpal depth is usually 0.1-0.2 mm in to the dentin. While maintaining the same depth and orientation ,bur is moved to extend the outline to include the central fissure and opposite pit ,if necessary.

How does the pulp form?

The dental pulp develops from the neural crest cells in the fetus which condense to form the dental papilla. The mature pulp has a layer of highly specialized cells called odontoblasts that lie around the outer borders of the pulp. The dental pulp itself has a rich supply of blood vessels and nerves.

What is an overhang in dentistry?

Overhanging dental restorations (ODR) are a major dental health problem. An ODR is defined as an extension of restorative material beyond the confines of a cavity preparation. They have been strongly implicated as an etiologic factor in the progression of periodontal disease and are alarmingly prevalent.

What is pulp root canal?

The pulp or pulp chamber is the soft area within the center of the tooth and contains the nerve, blood vessels, and connective tissue. The tooth’s nerve is in the “root” or “legs” of the tooth. The root canals travel from the tip of the tooth’s root into the pulp chamber.

Where is the pulp cavity located?

The pulp chamber is the upper section of the cavity contained within the crown of the tooth. The root canals are the lower section of the cavity found within the tooth’s roots.

What is a tooth?

tooth, plural teeth, any of the hard, resistant structures occurring on the jaws and in or around the mouth and pharynx areas of vertebrates. Teeth are used for catching and masticating food, for defense, and for other specialized purposes.

Can Pulpitis spread?

Irreversible pulpitis may lead to a type of infection called periapical abscess. This infection develops at the root of the tooth, where it causes a pocket of pus to form. If not treated, this infection can spread to other parts of the body, such as the sinuses, jaw, or brain.

What do you mean by Odontoblasts?

Definition of odontoblast : any of the elongated radially arranged cells on the surface of the dental pulp that secrete dentin.

What is tooth pulp made of?

Dental pulp is an unmineralized oral tissue composed of soft connective tissue, vascular, lymphatic and nervous elements that occupies the central pulp cavity of each tooth.

What is in pulp cavity?

The hard outer layer of the teeth is known as enamel. The sensitive tissue directly underneath the enamel is called dentine. At the centre of the teeth is the pulp cavity. This critical cavity contains the nerves and blood supply that keep the teeth alive.

What is dental pulp made of?

Dental pulp is composed of connective tissue, blood vessels, nerves, fibroblasts, and odontoblasts and develops from the dental papillae after being encased by dentin tissue (Huang et al., 2009).

What is isthmus in dentistry?

A canal isthmus is generally defined as a narrow, ribbon-shaped communication between two root canals that contains pulp tissue (Weller et al. 1995). The incidence of canal isthmuses varies for type of tooth and level within a given root (Vertucci 1984), but also appears to be age-related (Al Shalabi et al.

What is the strongest enamel margin?

The strongest enamel margin is that margin which is composed of full-length enamel rods that are supported on the cavity side by shorter enamel rods, all of which extend to sound dentin.

What materials can be used as a liner?

Varnish, calcium hydroxide, zinc phosphate, glass ionomer, and resin can be used as a liner. Bases are applied in thick layers to provide the pulp with thermal protection. These materials must be strong enough to support a restorative material during placement and function.

What's a gum pocket?

When gum tissue begins to separate or pull away from the teeth, it leaves a larger space between the tooth and gums where harmful bacteria can thrive. At this point the space is called a “pocket.” Inflammation is present, and the once healthy sulcus has become deeper because it is diseased.

What is overhang crown?

When a restoration is too bulky in the area where the restoration meets the tooth, we call it an overhang. A common sign of an overhang is difficulty flossing or floss that catches or tears. Overhangs can develop over time.

What cells form pulp?

Cells found in the dental pulp include fibroblasts (the principal cell), odontoblasts, defence cells like histiocytes, macrophage, granulocytes, mast cells, and plasma cells. The nerve plexus of Raschkow is located central to the cell-rich zone.

What are the zones of pulp?

The pulp cavity exhibits four zones as you progress from the dentin-pulp junction toward the center of the pulp cavity: 1) the odontoblast zone, 2) cell-free zone (basal layer of Weil), 3) cell-rich zone, and 4) the pulp core.

What causes infected tooth pulp?

A periapical tooth abscess occurs when bacteria invade the dental pulp — the innermost part of the tooth that contains blood vessels, nerves and connective tissue. Bacteria enter through either a dental cavity or a chip or crack in the tooth and spread all the way down to the root.

Is tooth pulp hard?

Your teeth are composed of four dental tissues. Three of them—enamel, dentin and cementum—are hard tissues. The fourth tissue—pulp, or the center of the tooth that contains nerves, blood vessels and connective tissue—is a soft, or non-calcified, tissue.

Can tooth pulp heal itself?

Unfortunately, the infected pulp of the tooth will not heal on its own and requires a root canal to properly be treated. Sometimes, patients may think a tooth infection has healed itself once they no longer feel pain in their tooth, but this just signals that the nerves inside of the tooth have died.

Can antibiotics cure pulpitis?

Antibiotics are not recommended in the treatment of irreversible pulpitis! There is insufficient scientific research to ascertain whether the use of antibiotics is helpful, studies show that antibiotics do not have any significant effect of reducing the pain from a toothache.

What are the home remedies for pulpitis?

Applying an icepack or cold compress may be a home remedy, but it is a proven way to reduce pain and swelling. This is an easy way to feel better until a dentist can examine the tooth. Warm salt water. Salt water offers some natural disinfecting properties.

How can I stop pulpitis pain?

Apart from removal of the tooth, the customary way of relieving the pain of irreversible pulpitis is by drilling into the tooth, removing the inflamed pulp (nerve) and cleaning the root canal. However, a significant number of dentists continue to prescribe antibiotics to stop the pain of irreversible pulpitis.
