Rationale of endodontic treatment
The document discusses focal infection and inflammation in the dental pulp. It describes how microorganisms from infected dental sites can spread through the bloodstream and lymphatic system, potentially causing infection elsewhere. When the pulp becomes inflamed in response to injury or infection, it undergoes degenerative or proliferative changes. The "FISH" study identified four zones of tissue reaction around an infected area: the zone of infection, contamination, irritation, and stimulation. Kronfeld's mountain pass theory applied this concept to explain the inflammatory response in the periapex as a defensive reaction analogous to a military mobilization.
Preventive resin restoration ppt
This document discusses preventive resin restorations (PRR), which involve sealing carious lesions and susceptible areas with resin to prevent further decay. PRRs are classified into three types based on the extent and depth of the lesion. Type A involves sealing shallow enamel lesions with resin or sealant. Type B uses resin filler for minimal lesions extending into dentin. Type C places a bevel and layers of resin composite to restore larger lesions extending into dentin. PRR provides advantages over traditional fillings by requiring minimal tooth preparation and sealing decay, while future replacements are less invasive than replacing fillings. Maintaining isolation from moisture is important for success.

In summary, the document serves as a comprehensive guide to functional appliances, their development and use in orthodontic treatment.
Dental splinting
Splinting is one of the oldest forms of aids to periodontal therapy. By redistribution of forces on the affected teeth the splint minimizes the effects caused by loss of support. Splinting teeth to each other allows weakened teeth to be supported by neighbouring teeth. This presentation reviews the rationale, techniques, advantages and ill effects of stabilization of teeth by splinting as an aid to periodontal therapy. With the acceptance and clinical predictability of adhesive procedures, the use of conservative bonding techniques to splint teeth offers a useful alternative to more invasive restorative procedures. Loss of tooth-supporting structures results in tooth mobility. Increased tooth mobility adversely affects function, aesthetics, and the patient’s comfort. Splints are used to overcome all these problems. When faced with the dilemma of how to manage periodontally compromised teeth, splinting of mobile teeth to stronger adjacent teeth is a viable option. This prolongs the life expectancy of loose teeth, gives stability for the periodontium to reattach, and improves comfort, function and aesthetics.
Bevels and flares in dental restoration

Fluid control & soft tissue management in fpd
Fixed partial dentures require careful fluid and soft tissue management during tooth preparation and impressions. Isolation techniques like rubber dams, high volume suction, and saliva ejectors help control fluids and retract soft tissues for optimal visibility and material properties. Gingival retraction further exposes the finish line and can be achieved mechanically using copper bands or retraction cords, or chemically using vasoconstrictors impregnated in cords. Temporary restorations protect the teeth until final prostheses are fabricated.

Gingival retraction further exposes the finish line and can be achieved mechanically using copper bands or retraction cords, or chemically using vasoconstrictors impregnated in cords. Temporary restorations protect the teeth until final prostheses are fabricated.

Oral prophylaxis
Oral prophylaxis, also known as teeth cleaning, is a dental procedure that removes plaque and tartar from tooth surfaces. It is generally performed using a scaler instrument to remove buildup above and below the gumline. Regular cleanings every 6 months are recommended for patients with good oral health to prevent periodontal disease. For patients with gum disease, a deeper cleaning called scaling and root planing is needed to remove tartar and bacteria from deep under the gums. The cleaning procedure involves removing supragingival and subgingival deposits using both hand instruments and ultrasonic scalers, followed by polishing, fluoride treatment, and home care instructions.
Strip Crowns Technique for Restoration of Primary Anterior Teeth: Case Report
Dental caries is the single most common chronic childhood disease affecting worldwide. In early childhood caries, there is early pulp involvement and gross destruction of maxillary anterior teeth as well as posterior teeth. Treatment of such caries represents a challenge to pediatric dentists especially, when teeth are badly destroyed. By the time the dentist sees the child, most of the coronal structure is lost. This case report describes challenging task of a Case of early childhood caries patients with mutilated maxillary incisors restored with a strip form composite restorations.
Journal of Clinical Pediatric Dentistry
This in vitro study investigated the effectiveness of the remineralizing agents Tooth Mousse and ProNamel in preventing dental erosion in both primary and permanent teeth. Enamel samples from extracted human teeth were treated with one of the agents or a control and then exposed to acid. Surface microhardness was measured before and after acid exposure. Both Tooth Mousse and ProNamel reduced enamel softening compared to the control, with ProNamel showing the greatest protective effect, especially in permanent teeth. The study suggests that remineralizing agents may help mitigate dental erosion.
interproximal reduction of enamel as part of orthodontics
1. Interproximal reduction (IPR) involves selective removal of enamel between teeth to create space for tooth movement. It is commonly used when there is moderate crowding or tooth size discrepancies.
2. IPR can be performed using mechanical methods like diamond-coated discs or strips, or chemically using phosphoric acid. It requires polishing afterwards to smooth surfaces and prevent problems like plaque retention.
3. IPR has advantages like avoiding extractions and reducing treatment time. However, it can alter enamel surface properties and increase caries risk if not followed by preventive measures like fluoride and good oral hygiene. The amount of enamel removed during IPR should not exceed recommended limits.

Principles of endodontic treatment
This document provides information on principles of endodontic treatment. It discusses the importance of rubber dam isolation to maintain asepsis during root canal treatment. The key components of a rubber dam kit and the technique for rubber dam application are described. Maintaining sterility of instruments is emphasized, and the decontamination cycle of cleaning, disinfection, inspection, packaging, sterilization and storage is outlined. Steam sterilization in an autoclave is recommended for reusable endodontic instruments, while cold sterilization is not an adequate replacement.
Ozone in dentistry.
Ozone has many applications in dentistry due to its powerful antimicrobial properties. It can be used to prevent dental caries by oxidizing bacteria and promoting remineralization of teeth. It is also effective for root canal disinfection and treatment of periodontal disease. Some advantages are that it is non-invasive and reduces the need for restorative treatments. Potential disadvantages include strict protocols for administration to avoid toxicity. Overall, ozone therapy is a valuable alternative or adjunct to conventional treatments in dentistry.
Field Isolation
The document discusses field isolation techniques in dentistry. The most complete isolation method is the rubber dam, which is a thin latex sheet used to isolate teeth during treatment. Key materials for rubber dam isolation include punches to punch holes in the dam, templates to mark hole positions, frames to hold the dam in place, and clamps to secure the dam to teeth. Other isolation techniques like cotton rolls and suction can be used when complete dam isolation is unnecessary. The rubber dam provides the highest level of isolation protection during dental procedures.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Different techniques for caries removal
- 1. بسم الله الرحمن الرحيم
- 4. Different techniques for caries removal
- 6. INTRODUCTION For more than a century, since the creation of belt-driven handpieces, dentists have been removing caries based on the concept of drill, remove, and restore. The remaining dentin is an essential feature for long-term pulpal health. Translated, this realization clearly means that removing excess dentinal tooth structure and encroaching on the pulpal tissue directly correlate to potential negative pulpal outcomes.
- 7. The different concepts in caries removal 1-Ozone therapy 2-Air abrasion technique 3-Chemomechanical caries removal 4-Smart bur 5-Stepwise excavation 6-Use of laser in tooth preparation 7-Use of ultrasonic in tooth preparation
- 8. Ozone therapy Ozone is a gas made up of three molecules of oxygen. When it is applied to bacteria and other organisms, the Ozone completely destroys them. It is used in dentistry by utilizing a special delivery system. The portable apparatus includes a source of oxidizing gas and a dental hand piece for delivering the gas/water to the target tooth at a concentration of 2100 ppm.
- 10. A cup attached to the hand piece is provided for receiving the gas and exposing a selected area of the tooth to the gas action. The ozone gas is refreshed in this disposable cup at a rate of 615cc/minute changing the volume of gas inside the cup over 300 times every second. The cup forms a seal around the lesion being treated so that ozone cannot leak into the oral cavity.
- 12. Air abrasion technique* •The use of air abrasion techniques in dentistry allows the removal of decayed tissue without the removal of the healthy tooth substance. *Reis-schmidt T. Air abrasion cavity-preparation system provide cutting-edge option in restorative dentistery :dent prod report 1998;32(12);57-60,108-9
- 14. • The apparatus involves minute abrasive particles which are too small to be seen by the naked eye carried to the target tooth by a stream of air gently and precisely acting to remove away the decayed tooth structure • It is recommended for treatment of children, pregnant women and other medically compromised patients.
- 16. Chemomechanical caries removal Chemomechanical caries provides painless and efficient removal of carious dentin and no administration of local anaesthesia.
- 17. This techniques is based on altering the secondary and /or quaternary structure of collagen in carious dentin by chlorination of the collagen. The hydrogen bonding in the collagen is disrupted rendering it more friable and easier to remove by scrapping the carious fragments away.
- 18. Smartprep (Smart bur) The SMARTPREP Instrument is a medical grade polymer that safely and effectively remove decayed dentin, leaving healthy dentin intact. The polymer instrument is self-limiting and will not cut sound dentin unless applied with great force, and then it will only wear away, rather than cut the healthy dentin.
- 21. laser in tooth preparation Lasers are used to remove decay within a tooth and prepare the surrounding enamel for receipt of the filling. Lasers are also used to "cure" or harden a filling.
- 22. Ultrasonics in tooth preparation The use of ultrasonic tips has become an alternative for cavity preparation. However, there are concerns about this type of device, particularly with respect to intrapulpal temperatures and cavity preparation time.
