Teeth Case – Zoom 100% (Dental X-ray)

Focused Area: Posterior teeth (molar region) with interproximal defect indicated by arrow


Full Analysis and Deep Radiographic Examination

This assessment is based on the provided dental X-ray image only and does not replace a complete clinical examination, periodontal probing, or additional radiographs if required.

Radiographic Findings

  • Radiolucent area between posterior teeth, consistent with interproximal dental caries

  • Possible loss of tooth structure at the contact point

  • Early signs of localized bone level reduction adjacent to the affected tooth

  • Existing restoration visible on the molar, suggesting previous decay history

  • No obvious advanced periapical abscess visible at this image depth, but early pathology cannot be ruled out


Probable Diagnosis

  • Interproximal dental caries (moderate depth)

  • Early periodontal bone involvement localized to the molar region

  • Increased risk of pulp irritation depending on cavity depth


Recommended Treatment Process

Step 1: Full Mouth Scaling and Polishing (Day 1)

  • Ultrasonic scaling to remove plaque and calculus

  • Manual scaling in posterior and interproximal areas

  • Polishing to reduce bacterial reattachment

Estimated duration: 45–60 minutes
Local anesthesia: May be required depending on sensitivity


Step 2: Definitive Interproximal Treatment (Day 1–7)

Based on X-ray depth and clinical findings:

  • Composite restoration for moderate interproximal decay

  • Replacement of failing restoration if margins are compromised

  • Root canal treatment if pulp involvement is confirmed

  • Crown placement if structural integrity is reduced


Healing and Recovery Timeline

Time Frame Expected Outcome
Days 1–3 Gum irritation decreases after scaling
Days 4–7 Stabilization of gingival tissues
Days 8–14 Healthy gum response if decay is treated

A 14-day healing period is realistic for soft tissue once infection sources are removed.


What Will Scale Up If Left Untreated

  • Expansion of interproximal decay into the pulp

  • Development of dental abscess or chronic infection

  • Progressive bone loss around the affected molar

  • Increased tooth mobility and eventual tooth loss

  • Higher cost and complexity of future dental treatment


Post-Treatment Care Instructions

  • Brush twice daily using fluoride toothpaste

  • Floss daily, especially between molars

  • Use interdental brushes if contacts are open

  • Maintain regular dental checkups and X-rays as advised


Professional Comment

Radiographic interproximal decay often progresses silently without pain. Scaling alone will not stop this condition. Early restorative treatment guided by X-ray findings is critical to preserve the tooth and surrounding bone.
