Dental Hygiene II

Course Description

DEH1802C – Dental Hygiene II is the second didactic course in Florida's Dental Hygiene A.S. curriculum, listed by Broward College at 3 credits and 48 lecture contact hours. It is taken as a corequisite with the second clinical course (DEH1802L) and follows successful completion of the first clinical experience.

The course marks the transition from learning to treat patients to treating patients with disease. Level I established the process of care on relatively straightforward cases; this level takes on periodontal disease as the central clinical problem, which is what most dental hygiene practice actually addresses.

Content covers periodontal assessment and classification in depth — the current staging and grading framework, radiographic bone loss interpretation, and prognosis; nonsurgical periodontal therapy including scaling and root planing as a defined treatment rather than a cleaning; advanced instrumentation with area-specific curettes and ultrasonic debridement for subgingival calculus; and re-evaluation — assessing tissue response after therapy and deciding whether to re-treat, maintain, or refer to a periodontist.

The course also covers adjunctive therapies including locally delivered antimicrobials and host modulation, pain management including local anesthesia where the program sequences it here, care for medically complex patients, and dental implant assessment and maintenance.

Offered at approximately 16 Florida institutions with CODA-accredited dental hygiene programs.

Major Topics

Required Topics

• Periodontal disease — etiology, pathogenesis, risk factors, and progression.
• Classification — current staging and grading of periodontitis; gingival conditions.
• Assessment — probing, attachment loss, furcation, mobility, and radiographic interpretation.
• Prognosis and treatment planning — case-based decision making.
• Nonsurgical periodontal therapy — scaling and root planing rationale, technique, and endpoints.
• Advanced instrumentation — area-specific curettes, adaptation in deep pockets, and sharpening.
• Ultrasonic instrumentation — mechanism, tip selection, power settings, and contraindications.
• Re-evaluation — timing, tissue response assessment, and decision to re-treat, maintain, or refer.
• Referral — indications for periodontal specialty care.
• Adjunctive therapy — locally delivered antimicrobials, systemic antibiotics, and host modulation.
• Pain and anxiety management — topical and local anesthesia, and nitrous oxide where applicable.
• Medically complex patients — treatment modification and medication implications.
• Implants and restorations — assessment, instrumentation considerations, and maintenance.
• Periodontal maintenance — interval determination and long-term management.

Optional Topics

• Periodontal surgery and the hygienist's role.
• Periodontal-systemic relationships.
• Peri-implant disease.
• Tobacco cessation as therapy.
• Nutritional counseling.
• Special health care needs.

Resources & Tools

• Periodontology for the Dental Hygienist (Perry, Beemsterboer & Essex), Elsevier — the core text for this level.
• Clinical Practice of the Dental Hygienist (Wilkins), Wolters Kluwer — the comprehensive reference.
• Fundamentals of Periodontal Instrumentation and Advanced Root Instrumentation (Nield-Gehrig).
• American Academy of Periodontology — the current classification framework and clinical practice guidance.
• ADHA — standards for clinical dental hygiene practice.
• Florida Board of Dentistry and Chapter 466, F.S. — scope of practice.
• Radiographic teaching files for bone loss interpretation practice.

Career Pathways

• Dental Hygienist (SOC 29-1292) — periodontal therapy and maintenance are the bulk of practice.
• Periodontal practice hygienist — specialty practice; this level is its direct foundation.
• Public Health Dental Hygienist — county health departments and FQHCs.
• Dental Hygiene Educator — requiring additional education.
• Corporate and clinical education roles.

Florida's older population sustains substantial periodontal maintenance demand, which makes this the most directly employable content in the program.

Special Information

How Florida dental hygiene programs split didactic from clinical

This is the structural fact that matters most for reading a dental hygiene transcript. Each level of the program is normally two paired courses — a didactic course and a clinical course taken as corequisites — and the credit counts diverge sharply. Broward College's sequence is representative:

Notice the pattern: as students advance, didactic hours shrink and clinical hours grow. Level III's lecture component is only 16 hours because by that point almost all learning happens with patients. Anyone evaluating transfer credit should compare the didactic-plus-clinical total for each level rather than a single course's credits, and programs differ in whether they run three clinical levels or four.

Prerequisites and corequisites

Broward College requires DEH1800L (Dental Hygiene I Clinic) with a minimum grade of C, with DEH1802L as corequisite. The didactic and clinical courses at each level are designed to run together, and programs do not generally permit taking one without the other.

Licensure

Graduates of a CODA-accredited program are eligible to sit the National Board Dental Hygiene Examination and a clinical examination, then apply for Florida licensure through the Board of Dentistry under Chapter 466, F.S. Florida permits dental hygienists to administer local anesthesia under specified conditions after board-recognized training.

Limited access, capped cohorts, and the minimum-grade rule

Florida dental hygiene programs are limited-access and highly competitive, with cohorts capped by clinic chair capacity. Programs require a minimum grade of C in every program course, and because courses run once a year in sequence, a single failure typically means waiting a full year to re-enter — if a seat is available.

Patient requirements are the recurring progression risk

Students must complete defined patient experience requirements at specified difficulty classifications to progress, and at many Florida programs recruiting those patients is substantially the student's own responsibility. Falling behind compounds, because patients must also return for completion. Track requirements continuously rather than assessing them at the end of a term.

Periodontal classification changed, and older material is out of date

Worth flagging for students and for anyone evaluating older coursework: the periodontal classification system was substantially revised, moving from the older "chronic/aggressive" categories to a staging and grading framework. Textbooks and continuing education material predating the revision describe categories no longer in use. Students should learn the current framework as the operative one and be aware that clinicians trained earlier may still use the older vocabulary.

The shift from "cleaning" to "therapy" is the conceptual core

Level I teaches students to remove deposits. This level teaches them that scaling and root planing is a treatment for a disease, with a diagnosis, a defined endpoint, an expected tissue response, and a re-evaluation to confirm it worked. Students who continue to think of the work as cleaning tend to under-treat and to miss the re-evaluation decision, which is where periodontal cases are actually managed.
