Conditions

Mandibular Nerve

Keywords

Presence of the anterior loop of the mental nerve (branching from the inferior alveolar nerve) will be recorded & its length will be measured

Outcome Measures

Primary Outcomes (1)

  • Prevalence of the anterior loop

    it will be measured using CBCT axial cuts (Ondemand 3D software)

    1 month

Secondary Outcomes (2)

  • length of the anterior loop

    1 month

  • Mesial extension of the anterior loop

    1 month

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adult Egyptian population including males \& females

You may qualify if:

  • CBCT scans of adult Egyptian patients, males and females.
  • CBCT scans with unilateral or bilateral anterior mandibles; with minimum 2 mm length distal to the mental foramen

You may not qualify if:

  • CBCT images of poor quality or artifacts interfering with the assessment of the anterior loop of IAN.
  • Scans showing any pathosis in the interforaminal area (tumor or impaction).
