The knowledge regarding the impacts and management of black triangles among dental professionals and laypeople.

This study aimed to assess the knowledge regarding impacts, causes and management of black triangles (BT) among participants from different educational backgrounds including dental students, dentists and laypeople. This descriptive cross-sectional observational research included 435 participants who comprised 4 groups: pre-clinical (3rd year) dental students, clinical (4th and 5th year) dental students, dentists, and laypeople. A constructed self-reported questionnaire was utilized to assess participants' demographic data and their knowledge of the impacts, causes and management of BT.

Relationships between perception of black triangles appearance, personality factors and level of education.

This analytical cross-sectional study evaluated the perception of black triangles (BT) and examined the relationships between the perception of BT, personality factors, different educational backgrounds and demographic factors. 435 participants were included and divided into four groups: dentists, clinical (4th and 5th year) dental students, pre-clinical (3rd year) dental students, and laypeople. Participants' perception of the attractiveness of smile profiles of maxillary and mandibular anterior dentition with BT was rated using a ten-point VAS scale with 0 being the least, and 10 being the most attractive smile profile.

Aim And Objective: This manuscript aims to provide an overview of the coronavirus disease-2019 (COVID-19) pandemic from dental perspectives, and presents standards and guidelines of dental care provision based on available research in this field as well as clinical experience and practice.

Background: The current COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is spreading around the globe and interferes with the provision of dental care for many individuals from different communities and backgrounds. A search for the literature on PubMed, ISI Web of Science, Scopus, EMBASE, and Cochrane Library from March 1, 2020 to December 30, 2020 was conducted.

Treatment of symptomatic, deep, almost cariously exposed lesions using ozone.

The aim of this controlled randomized crossover study was to assess post-treatment pain and the need for root canal treatment after the use of a traditional caries removal method followed by restoration, or after an ozone method of more conservatively managing the deep caries and a restoration. 84 participants (42 males and 42 females, mean age ± SD = 23.9 ± 2.

Serum levels of 25-hydroxy-vitamin D in patients with oral squamous cell carcinoma: Making a case for chemoprevention.

Objectives: Serum level of vitamin D has been used as a predictor for cancer development. We intend to measure the baseline vitamin D level in patients with oral squamous cell carcinoma (OSCC) and to compare same with non-cancer controls to determine any association.

Materials And Methods: Patients with OSCC presenting to our clinics were included in this study.

Randomized clinical trial on the comparison of bleaching outcomes using either ozone or hydrogen peroxide.

Objective: To evaluate the efficacy of in-office tooth bleaching following application of either ozone (O3) or hydrogen peroxide (H2O2).

Method And Materials: 32 participants were randomly distributed into two groups (n = 16 each). Participants' maxillary anterior teeth were treated with ozone (produced via a healOzone X4 device; Curozone) for 60 seconds in Group 1, or with 38% H2O2 for 20 minutes in Group 2.

Randomized controlled clinical trial on bleaching sensitivity and whitening efficacy of hydrogen peroxide versus combinations of hydrogen peroxide and ozone.

The clinical efficacy regarding bleaching sensitivity and tooth shade lightening using a standard hydrogen peroxide (HO) bleaching gel was compared with the additional use of ozone either before or after application of HO. Using computer-generated tables, 45 participants were randomly allocated into three groups (n = 15 each) in this investigator-driven, single-centre trial. In Group 1, upper anterior teeth were bleached using ozone (produced via a healOzone X4 device) for 60 seconds, then 38% HO for 20 minutes; in Group 2, 38% HO application (20 min) was followed by ozone (60 s); air produced by the healOzone machine (60 s) followed by 38% HO (20 min) was used in Group 3 (control).
