Non Surgical And Surgical Facial Aesthetics

Facial Aesthetic Treatments in Dentistry Scope: In some regions, dentists (with proper training) can provide minimally invasive facial aesthetic procedures that complement dental and smile esthetics. Common Treatments: Botulinum toxin type A (BoNT-A): Dynamic wrinkles → glabellar lines, forehead, crow’s feet. Therapeutic uses → masseter hypertrophy, bruxism-related symptoms, gummy smile. Duration → ~3–4 months. Hyaluronic acid (HA) fillers: Volume restoration/contouring → lips, nasolabial folds, marionette lines. Longevity → varies by filler type and depth of injection. Safety & Complications: Usually safe with proper training, asepsis, and anatomy-guided technique. Possible issues: Minor → bruising, swelling, asymmetry, Tyndall effect (HA). Serious (rare) → vascular occlusion (fillers), eyelid ptosis (BoNT-A). Risk reduction: Thorough medical history + informed consent. Slow/aspirational injections; use cannulas when suitable. Hyaluronidase available for HA complications. Emergency referral protocols for vision changes. Other Options: Surgical → lip lift, lower face/neck lifts, fat grafting (mainly plastic/maxillofacial surgery). Clinical Integration: When used appropriately, facial aesthetics can enhance smile design and patient satisfaction. Success depends on sound indications and realistic expectations.

Root Canal Therapy and Surgical Endodontics

Contemporary Non-Surgical Root Canal Treatment (NSRCT) Goal: Disinfect the root canal system + seal it in 3D. Key Techniques: Aseptic technique (rubber dam mandatory). Modern NiTi rotary/reciprocating instruments. Irrigant activation (sonic/ultrasonic). Bioceramic sealers for obturation. Outcomes: High success for primary NSRCT (>90% with traditional criteria). Success rates lower with CBCT-based evaluation or in complex medical/anatomical cases. Endodontic Microsurgery Indication: When orthograde NSRCT/retreatment fails to resolve apical periodontitis. Procedure: Apicoectomy → retrograde cavity prep → root-end filling with bioceramic material under magnification. Success: Modern series report ~85–90% pooled success. Prognostic Factors Size of pre-op lesion. Quality of coronal restoration. Density of root filling. Operator expertise. Follow-up: Structured recall visits with radiographic monitoring are essential.

Jaw joint dysfunction (TMJ) & Associated muscle treatments and Sleep apnea treatments

Temporomandibular Disorders (TMD) Types: Intra-articular → disc displacement, degenerative joint disease. Myogenous → muscle-related pain/dysfunction. First-line Treatment (evidence-based): Education & self-care. Jaw exercises, physiotherapy. Cognitive-behavioral therapy. Short courses of NSAIDs. Stabilization splints.→ These are conservative, reversible, and effective in many RCTs. Second-line / Advanced Care: Minimally invasive → arthrocentesis, intra-articular injectables (for persistent mechanical symptoms). Open surgery → only for clear structural pathology.   Oral Appliance Therapy for Sleep-Disordered Breathing Guidelines (AASM/AADSM 2024): Custom, titratable mandibular advancement devices recommended for: Adults with primary snoring. Adults with OSA who prefer them or cannot tolerate PAP. Most effective in mild-to-moderate OSA. Show better adherence than PAP in some patients. Best Practice: Dentists must coordinate with sleep physicians for: Diagnosis. Appliance titration. Follow-up & verification sleep testing. Emerging Approaches: Myofunctional therapy. Expansion techniques. Evidence still limited but growing.

Autogenous Human Growth Factor Treatments

Autologous Platelet Concentrates (PRF, A-PRF, i-PRF, CGF) What they are: Prepared from the patient’s own blood; contain growth factors (PDGF, TGF-β, VEGF) within a fibrin scaffold → help modulate wound healing. Main Benefits (based on systematic reviews): Improve soft-tissue outcomes → increased thickness, wider keratinized mucosa, faster early healing. Can aid bone healing (density, graft integration), though gains are modest if used alone. Specific Uses: Maxillary Sinus Augmentation: CGF (alone or with grafts) may enhance blood supply and new bone formation. A-PRF+ + biomaterials = better graft integration and implant stability. Peri-implant Soft Tissue: PRF can provide results similar to free gingival grafts for thickness/keratinized tissue. Grafts may still be superior in some measures, but PRF offers less pain, faster recovery, and lower cost. Limitations: Strongest evidence = soft tissue and early healing benefits. Less predictable for large bone volume gain if used alone. Evidence quality is variable (many small, heterogeneous RCTs). Clinical Takeaway:PRF/CGF are adjunctive tools—not replacements for grafting when significant bone volume is required. Case selection, standardized protocols (e.g., spin settings), and realistic expectations are essential.

Dental Implants and Guided Tissue Regeneration (GTR)

Dental Implants & Regeneration Implants: Osseointegrated implants are reliable for tooth replacement, with long-term success rates of 85–90% over 10 years. Success depends on patient health, implant site, and ongoing maintenance. Biological Risks: Main complications are peri-implant mucositis and peri-implantitis. Prevention requires careful surgical/restorative techniques, good soft-tissue (keratinized mucosa) management, and regular supportive care. Bone & Tissue Regeneration: Guided Bone Regeneration (GBR) and Guided Tissue Regeneration (GTR) use barrier membranes (resorbable like collagen, or non-resorbable like PTFE) to block soft tissue and allow bone/periodontal cells to regrow. These techniques help in ridge augmentation (horizontal/vertical) and repairing defects around implants. Bone substitutes may include xenografts, allografts, or alloplasts; soft-tissue substitutes can also be used. Decision Factors: Success depends on defect shape, need for space maintenance, and patient risk factors (e.g., smoking, poor blood sugar control). Managing complications (like flap design and membrane exposure) is key.
