The knowledge regarding the impacts and management of black triangles among dental professionals and laypeople. Sci Rep 2024; 14:10840. [PMID: 38735998 PMCID: PMC11089043 DOI: 10.1038/s41598-024-61356-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 05/05/2024] [Indexed: 05/14/2024] Open
Abstract
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. The VAS scale was used to assess participants' ratings for the impacts of BT on esthetics, with 0 meaning no impact and 10 meaning very severe negative impacts. The most reported treatments for BT were "cannot be treated" 99.3% and "non-surgical periodontal treatment" 67.1%. Meanwhile, the least reported was "modify the porcelain" 41.8%. The most reported cause of BT was "periodontal disease" 85.1%. However, the least reported were "parafunction" and "deep implants" 33.1% each. Dental professionals had better knowledge of the causes (t = 8.189, P < 0.001) and management (t = 8.289, P < 0.001) of BT than the non-dental participants. The dentists had the best knowledge, while the laypeople had the least knowledge of the causes (F = 62.056, P < 0.001) and treatment (F = 46.120, P < 0.001) of BT. The knowledge of the causes (t = 0.616, P = 0.538) and treatment (t = 1.113, P = 0.266) for BT was not significantly different between males and females. Age was not significantly related to the total knowledge about the causes (r = -0.034, P = 0.475) or treatment (r = -0.034, P = 0.482) for BT. Dental professionals had better knowledge of the impacts, causes and management of BT than the non-dental participants. The dentists were the best, while the laypeople were the worst in this regard. Age and gender had no relationships with the knowledge of causes or management of BT.

Mohd-Dom TN, Puteh SEW, Ayob R, Tennant M, Aljunid SM. Use of Quality-Adjusted Tooth Years as an Outcome Measure of Periodontal Treatment: A Quasi Experimental Study. JOURNAL OF ADVANCED ORAL RESEARCH 2020.

Abstract
Aim: To develop a simple approach to estimate quality-adjusted tooth years of teeth (QATY) treated for periodontitis and determine gains in QATY after undergoing cause-related periodontal therapy (CRPT). Quality-adjusted life years (QALY) gained for these patients were also determined. Materials and Methods: Patients newly diagnosed with periodontitis ( n = 165, 58.8% females, mean age 43.3 years) were recruited from periodontal specialist clinics. They received CRPT within a period of one year. We used the EuroQoL 5 Dimension (EQ-5D) and the Malaysian Oral Health Impact Profile (OHIP-14) indexes to measure changes in quality-of-life after one year of periodontal treatment. We then used these two scores to calculate their respective utilities and subsequently calculated QALY and QATY. Results: Proportions of deep periodontal sites (≥ 4 mm) decreased from 32.7% to 23.2% and patients gained an average of 0.3 mm of clinical attachment level per tooth at post-treatment follow-up. Improvements in means of OHIP-14 scores from 20.30 to 12.7 were consistent with changes in EQ-5D utilities from 0.81 to 0.91. Treated teeth gained 20.4 years for longevity while patients gained 17 QATYs. This is in line with the increase of 3.8 QALYs. Both treatment outcomes and clinical parameters were statistically significant at P < .0001. Conclusions: The method of estimating QATY using utilities derived from OHIP-14 combined with tooth life expectancy demonstrated that it may be used to measure effective treatment outcomes and is found to be consistent with improvements in QALY scores as calculated using EQ-5D-3L.

The Impact of Subject Age, Gender, and Arch Length on Attitudes of Syrian Dentists towards Shortened Dental Arches. Int J Dent 2015; 2015:643176. [PMID: 26265916 PMCID: PMC4523669 DOI: 10.1155/2015/643176] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2015] [Revised: 06/12/2015] [Accepted: 07/05/2015] [Indexed: 11/18/2022] Open
Abstract
Objective. This study aimed to investigate the impact of subject age, gender, and arch length on dentists' attitudes towards unrestored shortened dental arches. Materials and Methods. 93 Syrian dentists were interviewed and presented with 24 scenarios for male and female subjects of different ages and shortened dental arches of varying length. Participants were asked to indicate on a standardized visual analogue scale how they would value the health of the mouth if the posterior space was left unrestored. Results. A value of 0.0 represented the worst possible health state for a mouth and 1.0 represented the best. The highest mean value (0.73) was assigned to a shortened dental arch with missing second molar teeth in the mouth of a 70-year-old subject. A 35-year-old female subject with an extremely shortened dental arch (all molar and premolar teeth are missing) attracted the lowest mean value (0.26). The statistical analysis indicated a significant decrease in the value placed on unrestored shortened dental arches as the number of remaining teeth decreased (p < 0.008). While subject gender had almost no impact on dentists' attitudes towards shortened dental arches, the scenarios for the older shortened dental arch subjects attracted significantly higher values compared to the scenarios for the younger subjects (p < 0.017). Conclusion. Subject age and arch length affect dentists' attitudes towards shortened dental arches, but subject gender does not.

Abstract
OBJECTIVE This study aimed to use a utility method in order to assess dentists' preferences for the restoration of shortened dental arches (SDAs) with partial dentures. Also, the impact of patient age and length of the SDA on dentists' preferences for the partial dentures was investigated. MATERIALS AND METHODS Totally, 104 subjects holding a basic degree in dentistry and working as staff members in a private dental college in Saudi Arabia were interviewed and presented with 12 scenarios for patients of different ages and mandibular SDAs of varying length. Participants were asked to indicate on a standardized visual analog scale how they would value the health of the patient's mouth if the mandibular SDAs were restored with cobalt-chromium removable partial dentures (RPDs). RESULTS With a utility value of 0.0 representing the worst possible health state for a mouth and 1.0 representing the best, dentists' average utility value of the RPD for the SDAs was 0.49 (sd= 0.15). Mean utility scores of the RPDs across the 12 SDA scenarios ranged between 0.35 and 0.61. RPDs that restored the extremely SDAs attracted the highest utility values and dentists' utility of the RPD significantly increased with the increase in the number of missing posterior teeth. No significant differences in dentists' mean utility values for the RPD were identified among SDA scenarios for patients of different ages. CONCLUSION Restoration of the mandibular SDAs by RPDs is not a highly preferred treatment option among the surveyed group of dentists. Length of the SDA affects dentists' preferences for the RPD, but patient age does not.
