The primary cohort comprised 811 adolescents aged 13\u201315\u202fyears recruited from Suo County Middle School, who underwent clinical oral examination and completed the Child Oral Impacts on Daily Performances (Child-OIDP) questionnaire to evaluate oral-health-related quality of life (OHRQoL).

However, this cohort did not complete a validated OHRQoL instrument and was not included in the primary analyses. Clinical examinations assessed dental status using the Decayed, Missing, and Filled Teeth (DMFT) index, gingival bleeding, and dental calculus.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Clinical examinations revealed a high prevalence of oral-health problems among Tibetan adolescents (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f811): 48.7% had DMFT &amp;gt;0, 68.9% exhibited gingival bleeding, and 50.3% presented with dental calculus. The Child-OIDP questionnaire demonstrated moderate overall QoL impairment (mean score: 17.6% of maximum), with 75.6% reporting at least one oral impact. Eating was the most affected domain (mean score: 1.1).
