Fig. 14 Cubicle clinic for utilizing dental auxiliary personnel.

auxiliary personnel ie illustrated by Fig. 14. The location of the main and secondary aisles permits the instructor to move from one work station to another without retracing his steps,

Cubicle Dimensions Cubicles in existing dental schools range in size from 6 ft 4 in. by 7 ft to 7 ft 8 in, by 9 11 6 in. Whoie dental assistants will be used, a cubicle of 6 ft 9 in. by 9 ft 6 In. is desirable For students working alone, a cubicle of 7 ft 6 in. by 7 ft 6 in. is adequate.

Cubicles may be either partially or fully enclosed. A partition height of approximately 5 ft is recommended for most cubicles. This provides privacy, yet allows tor supervision and gives an impression of spaciousness. A 4*f1 partition topped by a 1-fl-high translucent plaslic panel may be used. Allowing an open space between partition end floor facilitates cleaning. However, one or two fully enclosed cubicles are desirable in every clinic.

Determining the Number of Clinic Positions

For the clinics as a whole, at least two operating positions should be provided for every entering class student one in the general clinic and one in the group of special clinics,

Every school should also plan additional clinic positions for its graduate and postgraduate sludents. The equivalent of one studenl modulo is desirable in the general clinic for even a modest program of advanced study. Additional positions will also be needed in the special clinics, with the number dependant upon the goals of ihe school and the particular dental specialities emphasized in its graduate curriculum.

Estimating Space Requirements

Space allowances for each operating position will also vary in the different clinics. The diagnostic clinic will require 85 sq ft per position, an allotment also sufficient for oral surgery.

In the radiology clinic. 115 sq lt per position should be allowed. and in the clinic tor the chronicelly ill and handicapped. 125 sq It. For other clinics. an al Iowa nee of 100 «q ft per Student position should be adequate,

Space allowance for somo of the supportIng facilitios nf the clinical departmenls will be foirly Standard. For demonstration op-eratories, tor example, a uniform allowance of 200 sq ft each may be used



The seminar is a room especially planned to accommodate small-group instruction tor 16 students or less, usually at an advanced level of training.

In most schools, one or more seminar rooms will be needed tor the use of each basic science department at least one for instruction and perhaps one for departmental conferences.

In the clinical facilities of most schools, each of the special clinics will need one seminar room for treatment planning and consultation, and the general clinic will need more than one. In programming, a reasonable standard for the general clinic would allow four rooms for a class size of 96, increasing or decreasing ihe number by oiig tor each 16-student module added or subtracted.

Allow a minimum of 300 sq ft lor each seminar room, with increments of 75 sq ft for every tour students beyond the 16 accommodated in the standard room.

Seating arrangements in seminar rooms are a matter of choice. Usually the instructor and his students sit around n central table, but some seminar rooms are furnished with standard tablet-arm chairs. Unitized folding tables and folding chairs permit maximum flexibility in seating arrangements, however, and their use is increasing, especially in the »«minai room used for showing slides, 16mm films, and other visual aids. If it is so used, a smalt adjoining room tor storage of visual aid materials is also helpful. A seminar, like any other instruction room, should be equipped with a chalkboard.

Lecture Rooms

Although they accommodate a minimum of 50 people, all lecture rooms need not have the same capacity. The smallest should, however, seat at least a full class, plus an overrun of 20 percent- If the school expects a Inter expansion in class size, lecture rooms should be planned from the beginning to accommodate it. and the 20 percent overrun allowance should also he based on the larger figure.

A good rule of thumb is to provide seating capacity for one ndditional 16-student module beyond class size in schools with 96 ECS- An allowance of 12 sq ft per seat (roughly 200 sq ft for a studenl module of 16) is sufficient to permit an adequate aisle on either side of the seating area and, in a large lecture room, a center aisle as well.

A minimum of three lecture rooms should be provided, one for use of the basic science departments and located near them, one for clinical arid preclinical instruction and accessible to the clinics, and one for special courses or for multiple use. In the school which will have no auditorium, the multiple-use lecture room mighl be designed to provide 271- positions per ECS All lecture rooms should be located so as to minimize noise and traffic congestion in the corridors.

Layout It may be difficult to decide whether the lecture room should be long and relatively narrow, like the usual hall, or wider and shallower, like an amphitheater. Because of its wide viewing angle, the amphitheater is not particularly suitable for the showing ol slides and films On the other hand, instructors favor-

ing the chalk talk technique often dislike a long room. Television monitors can be used In either type.

Every lecture room should be equipped with a targe chalkboard, a minimum of 12 lin ft is recommended- If, because of the size of the room, a raised platform is provided, It should be long enough to extend 2 ft beyond each end of the chalkboard. Projection screens which can be automatically lowered and raised may also be a part of the permanent equipment.

The floors of lecture rooms should be sloped or terraced slightly to provide a good view of the chalkboards and projection screen.

Some larger lecture rooms are split level or have a balcony. Whenever possible, students should enter from the rear.

Furnishings. Fixed or movable tablet-arm chairs, or auditorium seats equipped with tablet arms, are commonly found in lecture rooms. If the latter are used, iho aisle seat at the left of each row can be filled with an outside tablet arm for the use of left-handed students, Writing counters with individual seats are also frequently used.

Auditoriums, For schools that have ready access to them, auditoriums sometimes serve as lecture or examination rooms, As a rule.

however, programming committees will find it difficult to justify a large auditorium solely for the use of a dental school, since it is generally more economical to rent a hall for occasions such as graduations which require large seating capacity.

It an auditorium is planned, it should be located on a ground floor. Direct entry from the outside is necessary, because the auditorium will often be used by the public when the remainder of the school is closed. SeHting capacity should be sufficient to accommodate students enrolled in every program of the schoof as well as the total faculty.

Auditoriums must have public toilets and cloakrooms; a small lounge off the foyer is advisable, Areas lor the preparation and storage of demonstration materials should be provided backstage, as should a toilet room.

Areas for Study, Reference, end Research

Study Areas Places for first- ond second-year students should probably be located near the baste science laboratories, and those for third-arid fourth-year students near the clinics. If possible, they should be so situated that students will have access to them at all times, even when the rest of the school is closed. Space. About 19 sq ft per ECS should be allowed in planning standard study places for a schoof providing one study place for every two students. This type of study place can be in a common room, and is usually unassignad. However, some schools may prefer the par-tialty partitioned cubicle. Requiring approximately 48 sq ft per student position, the cubicles are furnished with a desk and choir, a coat locker, and storage space for books, microscopes, and school supplies. Because a cubicle is permanently assigned to each student, space requirements are based on the total enrollment.

Library Facilities The following guidelines, though general, may be helpful. Mending and Study Rooms, The main rending room should accommodate from 25 to 50 percent of the total number of students. Reading room exits should be controlled by book


metal * partition charge-out or loan desks, and the card catalog and circulation desk should be nearby. Carrels. Unenclosed desk areas of about 12 sq ft are useful for individual study and should be available in the ratio of one lor every 10 students. Small study rooms reserved for graduate and postdoctoral students are also an advantage- Either they should be soundproofed or located far enough away from the main reading room to permit students to use typewriters withoul disturbing others.

Microfilm. Auxiliary facilities such as a microfilm reading room, a sound tape room, and a rare book room are also desirable. Stacks. Stacks should be arranged to facilitate both storage and use of books- The stacks should be localed as close to reading rooms as possible, preferably at or below the level of the main reading room.

Stack area varies in proportion to volumes. Generous allowances should always be made for future expansion, Stack sections are usually 3 ft in length and 7 ft 6 in. in height, with a shelf depth of at least 10 in. One single-faced section 3 ft long will accommodate approximately 100 volumes. Service aisles between stacks should be at least 3 ft wide, and the main aisles at least 3 ft 8 in. wide. A microfilm room for processing and storage may be associated with the stack area.

Other Facilities. Acquisition and catalog rooms should he near the public card catalog and have direct access to the stacks.

Offices should be provided for the head librarian and an assistant, with the head librarian's office accessible both to staff rooms and to readers. Storage space for olfice supplies should be available.

A library stocked with 25,000 volumes and amply supplied with space for reading rooms and auxiliary facilities would require approximately 10,000 sq ft for a school with 96 ECS.
