The first step in organizing a dental presence at a practice might be to install a dental corner/table in the preparation room. However, it is much better to have a separate dental operatory (Figure 1.8). During dental procedures, significant contamination will be produced, including of an infectious aerosol. This is a specific situation in dentistry and thus it is important to separate the dental department from the rest of the surgical operatory. At the same time, all procedures will be performed under general anesthesia, so it is mandatory to provide the infrastructure for safe anesthesia (Figure 1.9).

Water plays a very important role in dental procedures, not only as a coolant, but also as a cleaning and flushing (lavage) medium. A source of demineralized water is necessary for the dental unit when using air‐driven handpieces, as the minerals in water can cause damage to them. Demineralized water provided by three‐way syringe or mechanical scalers can be supplied via containers attached to these devices. The water used for postoperative washing of the patient may be tap water, and it is convenient to have separate preparation and postoperative care tables with hot and cool water, a shower, and a bath (Figure 1.10a). Water used during dental procedures causes rapid loss of body temperature of the anesthetized patient, so the dental room must be equipped with all devices necessary for body temperature maintenance.

Central distribution of compressed air or nitrogen and of oxygen, as well as a central vacuum cleaner with convenient distribution of ports, will improve comfort and reduce noise and dirt (Figure 1.10b).

The small operating field must be well illuminated, using a light source as close as possible to natural.

Dental X‐ray is necessary for almost every dental procedure, so the X‐ray equipment must be close to the operating table and preferably wall‐mounted. Dental X‐ray generators do not require frequent changes of patient recumbency or position. Having a computer with radiography software in the operatory provides an easy way to evaluate digital scans immediately after exposure. Handheld devices may be very practical for a limited number of exposures or when the dentist must operate in a variety of places or in exotic locations without electricity supply, but this solution may be a safety concern in some countries (Figure 1.11).

Anesthesia equipment, including a cardiorespiratory monitor, should be placed so that it is visible to both the assistant or anesthesiologist and the surgeon or veterinarian. A portable anesthetic machine will be convenient if the clinic has several places where anesthesia is needed. The mounted version saves space, but it should be attached to a movable platform in order that it can be utilized in different sizes of patient (Figure 1.12). Anesthesia equipment is described in detail in Chapter 12.

Hygienic requirements are presented in Chapter 7, but in general the dental room should have good access so it can be kept clean and the walls can be disinfected. It should also have an air circulation with slightly negative pressure in order to enable the evacuation of toxic remnants of anesthetic gas and infectious aerosols, and to protect the rest of the clinic against contamination. Hazardous material containers should be easy accessible, correctly labeled, and highly visible (Figure 1.13).
