Information You Should Know About The Endodontic Motors

Endodontic instrumentation has advanced significantly in recent years with a range of powered rotary and reciprocating systems that can make root canal treatment easier to perform.

Endodontic electric motors are a part of this advancement as they provide clinicians with the ability to use special endodontic Nickel-titanium (NiTi) files.

NiTi rotary instrumentation should always be performed with slow-speed, low-torque electric motors with constant and precise torque suited to the canal being treated. Endo motors offer programmable settings, automatic reverse functions designed to reduce file breakage, and even integrated apex locators.

Dental equipments have three times more elastic flexibility in bending and torsion as well as superior resistance to torsional fracture when compared with size stainless-steel files that is why nickel-titanium files gradually force out hand stainless files.

NiTi files have many practical benefits:

 

— Predictable results every time even when dealing with  canals.

— Time Saving: with practice a standard molar can be totally cleaned and shaped in far less time than hand instrumentation.

— Less post-op pain owing to debris being extruded from the canal during the crown-down technique instead of being pushed through the apex during step-back.

— Less Fatigue for the operator compared to dental equipment.

— Less Transportation of canals.

Teeth with severely curved or S-shape roots should not be instrumented by rotary files to the working length because a NiTi file in a curved canal will have the tendency to straighten itself, resulting in transportation, zipping, and stripping.

Radius of curvature is the most significant factor in terms of predicting cyclic fatigue failure (separation) of the instrument.In other words, the more curved the canal, the greater the risk for separation.

What Is The Dental Surgical Light ?

The requirements laid down in national and international standards and draft standards provide helpful guidelines for optimum illumination (Fig. 1, Table I). General room illumination with 500 lx and illumination of the working area with 1000 lx are best achieved with a larger number of fluorescent lamps on the ceiling above and in front of the dental chair. Daylight white lamps with good color rendering are a good combination with changing daylight and the color of light of the operating light. The color of external skin, mucous membrane and teeth appears natural. The eight surgical lights examined differ in quality (Figs. 2-9). The maximum illuminance is between 9000 and 21 000 lx and is thus sufficiently high. The evenness of dental surgical light distribution within an ellipse 9 cm and 18 cm in diameter is between 1 : 4 and 1 : 15 (Figs. 10 and 11). Illuminance can be adjusted to the work in hand by means of controls. If the patient looks into the operating lights (Figs. 2c and 9c), maximum luminances of 5 cd/cm2-20 cd/cm2 occur 8 cm above the illuminance maximum in six operating lights. Luminances of more than 20 cd/cm2 cause squinting and running eyes. A light fitting with more than 200 cd/cm2 should not be used.

Besides the dental surgical light, we can also see the dental examination light during teeth treatment. A sharp fall in illuminance (distinct light/dark threshold) and low luminances to the patient’s eyes can be achieved with very directed light. Very directed light leads to very heavy shadows. Similarly, less specifically directed light leads to softer shadows so that objects in the oral cavity can be discerned easily, but the patient is no longer dazzled. The following operating lights can be recommended if the patient is to suffer as little glare as possible: Den-Tel-Ez Daray, and Belmont Type 040, Faro Sunlight S 70, Ritter Super Starlite; as well as: Chirana Fax, Siemens Sirolux. The following can be recommended for good illumination of the oral cavity: Belmont Type 040, Chirana Fax, Emda Top Spot, Faro Sunlight S 70, Pelton and Crane Light Fantastic Plus, Ritter Super Starlite, Siemens Sirolux. The color temperature, heat radiation, easy handling, stability and price are also important for qualitative assessment.

Ways To Improve the Efficiency of Air Compressor

Air Compressor is used throughout many modern laundering facilities, and goes unnoticed until there is a problem. A closer look at the air compressors in most laundry facilities reveals many simple opportunities to make quick, high impact changes that will lower power costs and keep air-powered equipment operating reliably. A systematic approach helps uncover the best steps to take based on the current situation.

Depending on the size of the operation, top-performing laundering facilities require a compressor between 5 and 15 horsepower. Air compressor manufacturers rate their equipment based on both the horsepower and air capacity (cfm or l/min). To get an idea of the actual cost to operate an dental air compressor, users are left to interpret the horsepower rating of each dental equipment.

For instance, why does one five horsepower compressor cost about a third as much as another? A close examination of the motor nameplate and air capacity of each quickly reveals that the two compressors are not really alike. To obtain the real cost of operation, examining the motor nameplate is a good place to start. The nameplate will reveal the voltage, operating amperes, nominal efficiency and power factor and the service factor of the motor.

About Its Material and Methods

Patient population

Sixty-one implants were inserted in 7 adult patients (4 female and 3 male; age range 38 to 62 years). All patients were free of any medical conditions interfering with implant treatment. Five (71.43%) patients were smokers and 2 (28.58%) were nonsmokers. All patients had been referred from general dentists and were not previously treated for periodontal disease at the time of the first examination.

Examination

Each patient underwent a comprehensive dental and periodontal examination. Periodontal charting included documentation of probing depths, recessions, clinical attachment levels, bleeding on probing, tooth mobility, furcation involvement, and plaque scores. Periodontitis was diagnosed in the presence of more than 4 sites with clinical attachment loss exceeding 4 mm, radiographic evidence of alveolar bone loss, and bleeding on probing. Impressions for diagnostic casts were taken and a panoramic radiograph was obtained. Casts were mounted on a semi-adjustable articulator after face-bow transfer and check-bite registration.

An occlusal analysis was performed, diagnostic wax-ups were prepared on the articulated casts, and restorative treatment needs determined. Once the restorative and periodontal treatment plans were established, radiographic and surgical guides were fabricated to facilitate implant placement. Table 1 shows the patient treatment plan and time schedule.

Periodontal treatment

Periodontal treatment, including surgical treatment if necessary, had been performed previously on all patients.

Implant selection

Unless outlined differently, cylindrical screw implants with a large-grit sandblasted and acid-etched surface and either a 1.8-mm or a 2.8-mm smooth neck were used (ITI Straumann Standard Plus with a 1.8-mm smooth neck; (ITI Straumann Standard with 2.8-mm smooth neck)Implant size was determined based on assessment with a panoramic radiograph taken with a radiographic stent in place, and a clinical examination.
