ABSTRACT

The aim of this paper was to evaluate marginal bone loss (MBL) and bone density (BD) in the alveolar bone surrounding the titanium implants with or without ultraviolet (UV) pre-treatment at different wavelengths in vivo. Randomized control trial conducted at the CMH Lahore Medical College, Institute of Dentistry. This interventional study enrolled patients undergoing replacement of missing teeth. Sixty-six Dio UFII implants with hybrid sandblasted and acid‑etched (SLA) surface treatments were divided equally into three groups. Control Group A was not irradiated, while implants in groups B and C were irradiated with UVA (382 nm, 25 mWcm²) and UVC (260 nm, 15 mWcm²), respectively. MBL and BD in the surrounding bone were evaluated at day 0 (baseline) and 8th and 26th week. SPSS 20.0 was used for data analysis. Repeated measure ANOVA followed by One-way ANOVA, Tukey’s test and Paired t-test were used for comparison. p ≤ 0.05 was considered statistically significant. Both UVA and UVC treated groups showed minimal MBL compared to control group, with no significant difference between the two experimental groups. Meanwhile, there was a steady increase in BD in all groups over time, with UVC showing a significant improvement between the 8th and 26th week. MBL was reduced and BD was increased in both UV‑treated groups. However, UVC irradiation has the potential to control MBL and produce denser bone in SLA‑coated implants.

Keywords: Bone density; cone beam computed tomography; marginal bone loss; photofunctionalization

ABSTRAK

Kajian ini dijalankan untuk menilai kehilangan tulang tepi (MBL) dan ketumpatan tulang (BD) dalam tulang alveolar yang mengelilingi implan titanium dengan atau tanpa rawatan awal ultralembayung (UV) pada jarak gelombang berbezasecara in vivo. Percubaan rawak terkawal dijalankan di Kolej Perubatan CMH Lahore, Institut Pergigian. Pesakit kajian intervensi ini dipilih menjalani penggantian gigi. Enam puluh enam implan Dio UFII dengan permukaan rawatan dibuat penyemburan pasir hibrid dan beretsa asid (SLA) dibahagikan sekata kepada tiga kumpulan. Kumpulan Kawalan A tidak diiradiasi, implan kumpulan B dan C diiradiasi dengan UVA (382 nm, 25 mWcm²) dan UVC (260 nm, 15 mWcm²). Mbl dan BD di sekeliling tulang dinilai pada hari 0 (garis dasar) dan minggu ke-8 dan ke-26. SPSS 20.0 digunakan untuk analisis data. ANOVA ukuran berulang dilakukan diikuti ujian One-way ANOVA, ujian Tukey dan t-test berpasangan digunakan untuk perbandingan. p ≤ 0.05 dianggap sebagai signifikan secara statistik. Kedua-dua kumpulan UVA dan UVC menunjukkan MBL yang minimal berbanding dengan kumpulan kawalan, dengan tiada perbezaan signifikan antara kedua-dua kumpulan uji kaji tersebut. Walau bagaimanapun, terdapat peningkatan tetap dalam BD pada kesemua kumpulan berkadar dengan masa, dengan UVC menunjukkan peningkatan signifikan antara minggu ke-8 dan minggu ke-26. MBL dikurangkan dan BD ditingkatkan dalam kedua-dua kumpulan yang dirawat dengan UV. Walau bagaimanapun, iradiasi UVC mempunyai potensi untuk mengawal MBL dan menghasilkan tulang yang lebih padat dalam implan yang disaduri SLA.

Kata kunci: Kehilangan tulang tepi; kepadatan tulang; pemfungsian cahaya; tomografi berkomputer cahaya kon
