occlusal trauma is injury to teeth or their supporting tissues caused by excessive or unfavorable biting forces. It is a clinical concept used in dentistry to describe how “bite” forces can contribute to tooth mobility, discomfort, or changes in the supporting bone. It is most commonly discussed in periodontics (gum and bone support), occlusion (how teeth meet), and restorative dentistry. It does not mean an infection; it refers to mechanical stress and the body’s response to it.

subantimicrobial doxycycline is a low-dose form of the antibiotic doxycycline used for its anti-inflammatory effects rather than to kill bacteria. It is most commonly used as an adjunct (add-on) to periodontal therapy for gum disease, especially periodontitis. At subantimicrobial doses, it is intended to influence the body’s tissue-destructive inflammatory response. In dentistry, it is typically discussed within “host modulation” approaches to periodontal care.

host modulation therapy is an approach that aims to reduce tissue damage by adjusting how the body’s immune and inflammatory response reacts to dental plaque. It is most commonly discussed as an *adjunct* (add-on) to periodontal (gum) treatment, not a replacement for cleaning the infection source. Instead of only targeting bacteria, it targets the patient’s “host response,” which can drive ongoing inflammation and breakdown. It is mainly used in the context of periodontitis management and related inflammatory gum conditions.

systemic antibiotics (perio) are prescription antibiotics taken by mouth (or, less commonly, given by injection) to support periodontal (gum) infection control. They work through the bloodstream, reaching gum tissues and periodontal pockets from the “inside,” rather than being placed directly into a pocket. They are most commonly used as an adjunct (add-on) to periodontal cleaning procedures, not as a standalone fix. Their use is selective and depends on the diagnosis, infection severity, and patient-specific factors.

minocycline microspheres are tiny, biodegradable particles that contain the antibiotic minocycline. They are placed by a dental professional directly into periodontal pockets (deep spaces between the tooth and gum). They are most commonly used as an add-on to deep cleaning for gum disease (periodontitis). Their goal is local antibiotic delivery at the site where harmful bacteria concentrate.

doxycycline gel is a prescription antibiotic gel that delivers doxycycline directly to a specific site in the mouth. It is most commonly used in periodontal (gum) care, placed into periodontal pockets alongside professional cleaning. It is designed for local drug delivery, meaning the medication is concentrated where it is placed rather than taken as a pill. Exact formulations and handling vary by material and manufacturer.

A local delivery antibiotic is an antibiotic placed directly into a specific site in the mouth where infection-related bacteria are concentrated. It is most commonly used in periodontal care, such as inside gum pockets around teeth affected by gum disease. Instead of treating the whole body, it targets a small area, usually as a gel, microspheres, or a small insert. Dentists may use it alongside professional cleaning procedures when localized bacterial control is needed.

chlorhexidine is a broad-spectrum antiseptic used to reduce bacteria in the mouth and on oral tissues. It is most commonly provided as a mouthrinse, but it can also be found in gels, sprays, and other delivery forms. Dentists and physicians may use it to support short-term plaque and gingivitis control and to lower microbial load around procedures. It is not a tooth filling material; it is an antimicrobial agent used alongside other dental treatments.

antimicrobial therapy is the use of treatments designed to reduce or control harmful microbes (such as bacteria). In dentistry, it can include medicated rinses, locally applied agents, or systemic medications when appropriate. It may also refer to restorative materials or bonding systems that are formulated to have antimicrobial effects. These approaches are commonly discussed in cavity management, gum (periodontal) care, and root canal–related infection control.

A recall interval is the planned time between routine dental follow-up visits. It is commonly used to schedule exams, professional cleanings, and preventive reviews. The recall interval can be the same for every patient in a practice, or tailored to individual risk. It helps organize ongoing care for teeth, gums, restorations, and oral health habits.
