+Arms and interventions

Arm	Type	Interventions	Description
Hemisection	Experimental	Procedure: hemi sectioning	patients in this group will have hemi sectioning to their compromised mandibular molars
dental implants	No intervention		patients will undergo extraction and replaced with dental implants

hemi sectioning (Procedure): one root will be extracted and the other root will be preserved

+Outcome measures

Primary outcomes

• Regulation of clinical signs and symptoms [12 months]: Patient-reported outcomes, including satisfaction, masticatory efficiency, and oral comfort measured by a visual analog scale (VAS).

Secondary outcomes

Assessment of radiographic bone changes [12 months]: * 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.

+Eligibility

Sex: All, ages: 21 Years to 60 Years, accepts healthy volunteers

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:

* 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.
