The module further covers asepsis, sterilization, and disinfection, enabling learners to differentiate between various decontamination methods and apply theoretical protocols to critical, semi-critical, and non-critical items. Proper waste management, environmental cleaning, and safe handling of sharps are emphasized to reduce occupational risks and prevent cross-infection. By integrating theoretical understanding with practical application, this module prepares dental assistants to uphold high clinical standards, ensure patient and staff safety, and contribute to effective infection control practices within the dental clinic.

The General & Specialty Dentistry module provides learners with a comprehensive understanding of the major branches of dentistry and the essential clinical concepts required to support safe and effective patient care. The module builds foundational knowledge across preventive, restorative, surgical, and specialty disciplines, allowing dental assistants to confidently support dentists during a wide range of treatments. Beginning with caries risk assessment and prevention, learners explore key oral diseases, their causes, and evidence-based preventive strategies that reduce treatment needs and improve community oral health.

The module then progresses through core clinical specialties—including operative dentistry, prosthodontics, endodontics, periodontics, orthodontics, and paediatric dentistry—where learners gain exposure to procedures, instruments, materials, and clinical workflows specific to each discipline in theory. Emphasis is placed on theoretical knowledge on chairside support, infection control, communication, and patient education to enhance safety, efficiency, and treatment outcomes. The final unit covers the etiology of malocclusion and the rationale for orthodontic treatment, preparing learners to understand dental development, treatment planning, and the interdisciplinary role orthodontics plays in comprehensive care. Overall, this module equips dental assistants with broad, practice-ready competencies that strengthen clinical performance and elevate the standard of patient care across general and specialist dental settings with theory knowledge.

The Oral Surgery & Diagnostic Imaging module provides learners with theoretical knowledge to assist safely and effectively in oral surgical procedures and dental radiography. The module introduces the scope of oral and maxillofacial surgery (OMS), covering common procedures such as surgical extractions, implant placement, trauma management, pre-prosthetic surgery, orthognathic surgery, and the management of oral pathology, tumors, and facial pain conditions. Emphasis is placed on the dental assistant’s critical role in pre-operative preparation, instrument setup, infection control, surgical support, and post-operative patient care.
