Quick reference

General Dental Surgery - Core Reference

  • Tooth notation: FDI two-digit system uses quadrant (1-4 upper right to lower left in permanent dentition) plus tooth number 1-8 from midline; universal numbering runs 1-32 clockwise from upper right third molar.

  • Eruption timing (primary): mandibular central incisors ~6-10 months, first primary molars ~13-19 months; permanent first molars and mandibular central incisors erupt ~6-7 years.

  • Local anaesthetic maximum doses (adult, 70 kg): lidocaine 2% with 1:100,000 epinephrine ~4.4 mg/kg (max ~300 mg); articaine 4% ~7 mg/kg (max ~500 mg); prilocaine ~8 mg/kg (max ~600 mg).

  • Pulpal diagnosis categories: reversible pulpitis (provoked, brief pain), irreversible pulpitis (spontaneous or lingering pain), necrotic pulp (no response to thermal/EPT), previously treated.

  • Periodontal staging (2018 classification): Stage I-III by interdental CAL (1-2 mm, 3-4 mm, ≥5 mm) and Stage IV by need for complex rehabilitation; grading A-C by progression rate (bone loss / age ratio).

  • Dental trauma: avulsed permanent tooth - handle by crown, store in saline/milk/HBSS, replant within 60 minutes if possible, splint flexibly 2 weeks; do not replant primary teeth.

  • Antibiotic prophylaxis for infective endocarditis is reserved for highest-risk cardiac conditions (prosthetic valve, previous IE, certain congenital heart disease); single dose amoxicillin 2 g 30-60 min pre-procedure.

  • Local haemostasis in dental surgery: direct pressure, suturing, topical haemostatic agents (oxidised cellulose, tranexamic acid rinse 4.8%); check INR for warfarin patients - >4.0 warrants liaison before extraction.

Unverified Domain - Official Structure Not Published

  • No authoritative domain taxonomy was available in the retrieved source; content here reflects commonly examined general dental surgery themes and should be treated as provisional.

  • Restorative materials: amalgam has high compressive strength and no adhesive bond; composite relies on enamel/dentin bonding and is technique-sensitive to moisture.

  • Caries risk assessment incorporates diet (fermentable carbohydrate frequency), fluoride exposure, salivary flow, plaque control, and past caries experience.

  • Endodontic working length is determined by apex locator and confirmed radiographically; biomechanical preparation uses crown-down or step-back concepts with copious irrigation (NaOCl 0.5-5.25%).

  • Oral medicine red flags: persistent ulcer >3 weeks, induration, unilateral symptoms, unexplained bleeding, or cervical lymphadenopathy warrant urgent referral for suspected malignancy.

  • Medical emergencies in the dental chair: syncope (supine, legs raised), hypoglycaemia (oral glucose if conscious), anaphylaxis (IM adrenaline 0.5 mg 1:1000 adult), angina (GTN sublingual).

  • Infection control: single-use items for needles and sharps; autoclave validation with biological indicators; hand hygiene per WHO five moments; sharps disposed immediately in UN-approved containers.

  • Radiographic selection follows ALARA and IR(ME)R principles: justify each exposure, use rectangular collimation and digital receptors, and apply a 2 mm lead-equivalent apron where appropriate.
