Inclusion criteria

  • Good oral hygiene and motivation for follow-up care.
  • Ability to understand and sign informed consent.
  • Localized Root/Periodontal Disease: Severe attachment loss or bone loss (e.g., severe localized periodontitis) affecting the mesial root, while the other root remains healthy.
  • Furcation Involvement: Class II or III furcation involvements where the disease cannot be treated by conventional methods.
  • Vertical root fracture confined to the mesial root.
  • Non-treatable perforation in the mesial root.
  • Extensive sub-gingival root caries affecting the mesial root.
  • Extensive un-treatable internal and external root resorption related to the mesial root.

Exclusion criteria

Exclusion Criteria:

  • Uncontrolled systemic diseases (e.g., diabetes mellitus, bleeding disorders, immunosuppression).
  • Fused or poorly shaped roots,
  • Active periodontal or endodontic infection at adjacent teeth that may interfere with treatment outcomes.
  • Severe bruxism or occlusal parafunction.
  • History of radiation therapy in the head and neck region.
  • Pregnancy or lactation.
  • Poor compliance or inability to attend follow-up visits.
  • Smoking more than 10 cigarettes per day.

Study arms

  • Experimental
    Hemisection

    patients in this group will have hemi sectioning to their compromised mandibular molars

    Procedure: hemi sectioning

  • No intervention
    dental implants

    patients will undergo extraction and replaced with dental implants

Interventions

  • Procedurehemi sectioning

    one root will be extracted and the other root will be preserved

What researchers measure

Primary outcomes

  1. • Regulation of clinical signs and symptoms

    Patient-reported outcomes, including satisfaction, masticatory efficiency, and oral comfort measured by a visual analog scale (VAS).

    Time frame: 12 months

Secondary outcomes

  1. Assessment of radiographic bone changes

    * Radiographic bone level changes around the retained root or implant. * Detection of any radiographic signs of pathology or treatment failure. Measurements will be recorded in millimeters (mm) using digital radiographic software calibration tools.

    Time frame: 12 months
