Dental Hygiene I

Course Description

DEH1800C – Dental Hygiene I is the first clinical course in Florida's Dental Hygiene A.S. curriculum. It is typically a 2-credit didactic course of roughly 32 contact hours, taken as a corequisite with a separate clinical course (commonly DEH1800L, Dental Hygiene I Clinic) in which students treat patients under supervision.

This is the point in the program where a student stops practicing on manikins and begins treating people. The didactic course prepares and supports that transition: planning the dental hygiene appointment, adapting treatment to the patient in the chair, and developing the clinical judgment that separates performing a procedure from providing care.

Content covers the dental hygiene process of care — assessment, diagnosis, planning, implementation, evaluation, and documentation — applied across the range of patients a student clinic sees. Cases progress from straightforward to specialized: geriatric patients with polypharmacy and dry mouth, pediatric patients requiring behavior management, adolescent patients, patients who are pregnant or menopausal, and patients with systemic conditions that alter periodontal risk or treatment safety.

Appointment planning gets real emphasis, because it is where new clinicians most often fail: sequencing procedures, estimating time realistically, selecting instruments, and adjusting a plan mid-appointment when the patient's tolerance or the tissue response is not what was expected.

Most programs also introduce local anesthesia here. Florida permits dental hygienists to administer local anesthesia under specified conditions after completing board-approved training, which makes it a substantive competency rather than an overview.

The course is offered at approximately 19 Florida institutions with accredited dental hygiene programs, including Broward, College of Central Florida, Daytona State, Eastern Florida State, Florida State College at Jacksonville, Gulf Coast State, Hillsborough, Indian River State, Miami Dade, Palm Beach State, Pensacola State, Pasco-Hernando, Santa Fe, South Florida State, State College of Florida, St. Petersburg, Tallahassee State, and Valencia.

Major Topics

Required Topics

• The dental hygiene process of care — assessment through evaluation, and documentation at each stage.

• Medically complex patients.
• Tobacco cessation counseling.
• Community outreach and public health placements.
• Ergonomics and clinician musculoskeletal health.

Resources & Tools

• Clinical Practice of the Dental Hygienist (Wilkins), Wolters Kluwer — the standard text; widely adopted across Florida programs.
• Fundamentals of Periodontal Instrumentation and Advanced Root Instrumentation (Nield-Gehrig), Wolters Kluwer.
• Darby and Walsh Dental Hygiene: Theory and Practice, Elsevier — a common alternative.
• Handbook of Local Anesthesia (Malamed), Elsevier — the standard reference for the anesthesia component.
• CODA (Commission on Dental Accreditation) — the programmatic accrediting body; accreditation governs licensure eligibility.
• Florida Board of Dentistry and Chapter 466, Florida Statutes — scope of practice, including hygienist local anesthesia requirements.
• ADHA — standards for clinical dental hygiene practice.
• Student clinic, instruments, ultrasonic units, radiographic equipment, and simulation laboratory.

Career Pathways

• Dental Hygienist (SOC 29-1292) — the target occupation; private practice, group practice, and public health settings.
• Public Health Dental Hygienist — county health departments, school-based sealant programs, and FQHCs.
• Periodontal practice hygienist — specialty practice with more complex therapy.
• Dental Sales and Corporate roles — product education and clinical support.
• Dental Hygiene Educator — requiring a bachelor's or master's degree.
• Public health and program administration — with a B.A.S. or B.S. in dental hygiene or public health.

Florida's older population sustains substantial periodontal maintenance demand, and dental hygiene is consistently among the better-compensated associate-degree occupations in the state. Employment is distributed statewide rather than concentrated in metropolitan areas.

Special Information

Course structure varies — check how your program splits it

Florida institutions organize this content differently, which matters for transfer. Gulf Coast State and Broward both list DEH1800 at 2 credits as a lecture course (32 contact hours at Broward) with a separate clinical corequisite: Broward's DEH1800L Dental Hygiene I Clinic is 2 credits and 128 clinical contact hours; Gulf Coast's is 4 credits at 16 lab hours weekly. Institutions using the DEH1800C designation integrate the didactic and clinical components into a single course. The figures recorded here reflect the didactic portion as most catalogs list it. Students and evaluators should compare the didactic-plus-clinical total rather than a single course's credits.

Prerequisites

Prerequisites are program-sequence based and strictly enforced. Broward requires DEH1002, DEH1002L, and DEH2400 each with a minimum grade of C, with DEH1800L and DEH2300 as corequisites; Gulf Coast requires DEH1002 and DEH1002L with a C or better. Admission to the dental hygiene program precedes all of it, and Florida dental hygiene programs are limited-access and highly competitive, with cohorts capped by clinic chair capacity.

Licensure

Graduates of a CODA-accredited program are eligible to sit the National Board Dental Hygiene Examination and a clinical examination, and must then obtain Florida licensure through the Board of Dentistry under Chapter 466, F.S. Local anesthesia administration requires separate board-recognized training, which is why the course introduces it formally rather than incidentally.

Clinical requirements are a real scheduling constraint

Clinical hours are substantial — Broward's corequisite clinic alone runs 128 contact hours — and students must complete defined patient experience requirements to progress. Recruiting patients for the student clinic is frequently the student's own responsibility, and falling behind on required patient experiences is a common reason students do not progress on schedule. Programs also charge laboratory and insurance fees; Broward's listed clinic fees exceed $160 for this course alone.

Minimum-grade rules apply throughout

Dental hygiene programs require a minimum grade of C in every program course. Because cohorts are capped and courses run once a year in sequence, a single failure typically means waiting a full year to re-enter, if a seat is available.
