📌 Introduction

During the past three years of studying dentistry, we have experienced a demanding and intensive academic and clinical journey. The program required continuous effort, dedication, and patience, as we moved from theoretical learning to hands-on clinical practice. Despite the challenges, this period has been highly valuable in developing our skills, knowledge, and confidence in dealing with patients and various dental cases.

Throughout our clinical training, we were exposed to a wide range of dental procedures. Dental cleaning (scaling and polishing) was one of the basic yet essential procedures that helped us understand oral hygiene and the prevention of periodontal diseases. Tooth extraction taught us how to manage non-restorable teeth and deal with patient comfort and post-operative care.

We also learned about fillings, which are used to restore teeth affected by caries and to preserve their function and structure. Root canal treatment (endodontics) was a more advanced procedure that involved treating infected or inflamed dental pulp to save the natural tooth.

In addition, we were introduced to dental crowns, which are used to restore the shape, strength, and appearance of damaged teeth. Fixed prosthodontics, such as bridges, helped us understand how to replace missing teeth permanently, while removable prosthodontics allowed us to learn how to design and provide dentures for patients with multiple missing teeth.

Overall, these three years have been a challenging yet rewarding journey that significantly shaped our clinical abilities and prepared us for future professional practice in dentistry.

🤍 Dedication

All praise is due to Allah, by whose grace good deeds are accomplished, and by whose guidance we achieve our goals and aspirations.

We dedicate this humble work, the outcome of years of effort and hard work, to those who were the reason, after Allah, for our reaching this stage; to those who gave us endless love and support, to our dear parents who have always been our first source of strength and encouragement, and to our beloved families who shared this journey with patience and motivation.

We also dedicate this work to our respected professors at the College of Dentistry, University of Science and Technology, who illuminated our path with knowledge, never hesitated to guide and teach us, and played a major role in building our academic and clinical foundation.

To our colleagues and classmates who accompanied us throughout this journey, sharing both the hardship and success, and leaving us with the most beautiful memories and sincere moments.

We dedicate this achievement to everyone who believed in us and supported us until we reached this moment.

Introduction to Dental Cleaning

Oral hygiene is the cornerstone of maintaining overall health, rather than being a mere daily cosmetic routine. The mouth serves as the primary gateway to the body; neglecting its cleanliness leads to the accumulation of dental plaque, a sticky film of bacteria that constantly forms on tooth surfaces.

If this layer is not removed regularly, it hardens into “tartar” (calculus), which is difficult to remove. This paves the way for health issues starting with tooth decay and gum disease, and may escalate to more serious complications affecting heart health and the digestive system. Therefore, cleaning teeth correctly using the right tools is not just a habit—it is a long-term investment in quality of life and disease prevention.

Home care with brushing and flossing is considered the “first line of defense,” but it alone is not enough to reach every intricate corner. This is where professional dental cleaning comes in; it is an indispensable preventive and therapeutic procedure for maintaining long-term oral health.

Dental Cleaning Tools

• Dental Mirror: Used for indirect vision and reflection of light.
• Explorer: A sharp tool used to detect cavities and tartar.
• Ultrasonic Scaler: Uses vibrations and water to remove tartar.
• Hand Scaler: Manual tool for removing tartar from teeth surfaces.
• Polishing Brush & Rubber Cup: Used with paste to polish teeth.

Cleaning Procedures & Treatment Steps

1. Clinical Examination: Goal: Examine before treating; observe and diagnose before starting treatment.
2. Motivation: Building a connection with the patient to help them understand oral health importance and inspire habit changes.
3. Education & Instruction: Providing knowledge about oral condition and teaching proper oral care.
4. Teeth Scaling: The first step in physical cleaning.
5. Teeth Polishing: Smoothing tooth surfaces and removing external stains using a rotating brush/cup and prophylaxis paste.
6. Medicine Writing & Follow-up: Supporting mechanical treatment with pharmacological aid and long-term maintenance.

Post-operative Instructions After Dental Cleaning

• Avoid eating or drinking for 30 minutes if fluoride was applied.
• Mild sensitivity may occur and usually disappears within a few days.
• Brush teeth twice daily using a soft toothbrush.
• Use dental floss daily to clean between teeth.
• Avoid very hot or very cold foods for the first 24 hours if sensitivity occurs.
• Maintain good oral hygiene and visit the dentist regularly (every 6 months, or 3–4 months for smokers/diabetics).

Importance of Professional Dental Cleaning

• Removing hard tartar (calculus).
• Accessing periodontal pockets beneath the gum line.
• Removing stubborn external stains (coffee, tea, smoking).
• Early examination to detect cavities or gum issues.

Introduction

Dental extractions are routine treatments. While modern dentistry focuses on preserving natural teeth, extractions remain commonly performed. Non-surgical removal relies on the progressive expansion of the bony socket, creating mobilization to remove the tooth.

Anatomy and Physiology

Indications for Extraction

• Dental Caries
• Pulpal/Apical Pathology
• Severe Periodontal Disease
• Fractured Teeth
• Retained Roots
• Impacted Teeth
• Supernumerary Teeth
• Orthodontic Reasons
• Pre-prosthetic Extractions
• Tooth in a Fracture Line
• Prior to Radiotherapy

Contraindications & Systemic Factors

• Uncontrolled Medical Conditions: Epilepsy, uncontrolled hypertension, severe CVD.
• Respiratory Conditions: COPD (prefer sitting position; caution with sedation).
• Renal & Immunocompromised: Risk of bleeding and infection; antibiotic prophylaxis may be considered.
• Antiresorptive Agents: (Bisphosphonates/Denosumab): Risk of MRONJ. Drug holidays are not advised.
• Anticoagulants / Antiplatelets: Warfarin patients with INR < 4.0 can be treated safely in primary care using local hemostatic measures.
• Radiotherapy: Risk of Osteoradionecrosis (ORN).
• Proximity to Vital Structures: Inferior Dental Nerve (IDN) or Maxillary Sinus (risk of OAC).

Extraction Instruments

Examination Tools: Mirror, Explorer, Cotton Pliers.
Anesthesia Tools: Syringe, Needle, Carpule.
Soft Tissue Tools: Periosteal Elevator.

2. Do not rinse or spit forcefully for 24 hours.
3. Do not use a straw; avoid smoking for at least 24 hours.
4. Eat soft, cool foods; avoid hot, hard, or spicy foods on day 1.
5. After 24 hours, gently rinse with warm salt water 2–3 times daily.
6. Apply cold compress for swelling if needed.
