    Background One of the most common causes of aesthetic failure and restoration replacement is the tooth restorations color mismatch specifcally after aging. Methods One hundred and two participants with endodontically treated frst molar were selected clinically. The patients were randomly splited into two groups and restored either with Cerasmart hybrid ceramic or Vita Enamic polymer infltrated ceramic network (PICN) crowns and cemented using dual cure adhesive cement. The color difer- ence (ΔE) values after cementation at 0 (Baseline), 6, and 12 months of use were obtained by quantifcation of L*, a*, and b* values with a digital spectrophotometer. Mann–Whitney test used to compare between tested groups at each time point and between (α=0.05). Results At 6 months follow-up intervals, Vita Enamic group showed the highest signifcant ∆L* (p=0.035) and ∆a* (p<0.001) compared to Cerasmart group. ∆b* and ∆E showed no signifcant diference between both groups (p>0.05). Furthermore, all color parameters of both groups showed statistically signifcant diference at 12 months follow-up intervals. After 12 months, Vita Enamic restorations presented higher color change compared to Cerasmart restorations with a (p-value of 0.0120). When comparing the total color diference ∆Et through-out the follow-up intervals of Vita Enamic & Cerasmart groups, there were insignifcant diference (p=0.263). Conclusion Both hybrid materials demonstrated comparable color stability after 1 year of clinical service within clini- cal acceptance range. However, Cerasmart demonstrated a better colour stability after 1 year. Trial registration ClinicalTrials.gov (ID: NCT05501808) 15/8/ 2022- ‘retrospectively registered’.

    Diode laser in management of loss of taste sensation in patients with post-COVID syndrome: a randomized clinical trial

    Objective Loss of taste (ageusia) is a symptom observed following recovery from COVID-19 infection. The loss of taste and smell sensation may negatively affect patients’ quality of life (QoL). The present study aimed to evaluate the effectiveness of the Diode Laser in managing loss of taste sensation in patients with post-COVID syndrome versus the placebo. Material and method The study sample was 36 patients who complained of persistent loss of taste sensation following COVID-19. The patients were randomly assigned to one of the two groups according to the received treatment: Group I (laser treatment) and Group II (light treatment), with each patient receiving a diode laser treatment or placebo from the same operator. Taste sensation was subjectively measured after treatment for four weeks. Results The results demonstrated a significant difference between both groups regarding taste restoration after one month (p=0.041), with Group II having a significantly higher percentage of cases 7 (38.9%) with partial taste restoration. In contrast, a significantly higher proportion of Group I 17 cases (94.4%) had complete taste restoration (p<0.001). Conclusion The present study concluded that using a Diode laser 810 nm aided in a more rapid recovery from loss of taste dysfunction.
