Introduction: Currently, the non-extraction treatment philosophy is gaining popularity among orthodontic patients and this has affected therapeutic modifiability. The different techniques employed in treating patients in this manner have their effects on the profile, the periodontium, as well as the stability of treatment results. Chiefly, labial movement of mandibular incisors has traditionally been considered a risk factor for periodontal problems predominantly, gingival recession. The present study investigated the effects of unraveling mandibular crowding on the periodontium utilizing two of the non-extraction treatment modalities namely; dental expansion and interproximal enamel stripping following orthodontic treatment in adult orthodontic patients. Material and methods: The sample consisted of 20 adult patients (16 Females, 4 Males) divided among 2 groups. In group 1, patients were treated by means of dental expansion while in group 2, interproximal enamel stripping was performed to resolve the crowding. All patients selected in both groups shared common selection criteria of: Class I Molar crowding cases according to Angle{u2019}s classification with moderate crowding in the mandibular arch (4-8 mm), a healthy systemic condition, proper oral hygiene prior to the treatment as well as periodontal health in terms of absence of bleeding on probing, absence of periodontal pockets, as well as no attachment loss
