(2018) AlHumaid, Jehan; El Tantawi, Maha; AlAgl, Adel; Kayal, Shaden; Al Suwaiyan, Zainab; Al-Ansari, Asim
Background: Health education advocates regular dental visits to improve oral health. There is a need to verify the outcomes associated with various dental visits patterns. Objective: To assess the relationship of reported and clinically assessed oral health outcomes in Saudi children with their dental visits' pattern. Methods: This cross-sectional study included 6–12-year-old schoolchildren from six cities in the Eastern Province of Saudi Arabia in 2015. Parents responded to a questionnaire about dental visit patterns. Through a clinical examination, the presence of caries, sealants and need for referral was assessed. Univariate and multivariate regression was used to assess the association between dental visit patterns and pain in the past 6 months, presence of untreated caries and need for referral after controlling for confounders. Results: Of the 3000 questionnaires distributed, 2306 (76.9%) parents responded. Significantly higher odds of pain were associated with visiting when in dental pain (odds ratio = 6.81) and never visiting a dentist (odds ratio = 3.44), whereas significantly lower odds were associated with regular checkups (odds ratio = 0.28). No significant association was observed with visits after recall by dentists. Conclusion: Regular checkups initiated by parents are associated with better reported oral health outcomes in terms of pain, while recall by dentists has no impact on oral health.
Effect of erbium laser on microtensile bond strength of fissure sealant in primary teeth: An in vitro study
(2018) AlHumaid, Jehan; Alagl, Adel; Bedi, Sumit
Background: Laser etching has several advantages as compared with conventional acid etching. However, results of earlier studies on conditioning surfaces with erbium, chromium:yttrium–scandium–gallium–garnet (Er, Cr:YSGG) before application of the fissure sealant have been inconclusive. Aim: The study aimed to evaluate the microtensile strength of resin-based fissure sealant bonded to primary enamel conditioned by Er, Cr:YSGG laser with varying power outputs. Materials and Methods: Fifty sound primary first molars were randomized into the following five groups based on pretreatment choice: Group 1: 3.5 W laser etching + acid etching; Group 2: 2.5 W laser etching + acid etching; Group 3: 3.5 W laser etching with no acid; Group 4: 2.5 W laser etching with no acid and Group 5: acid etching with no laser. Acid etch was performed with 35% orthophosphoric acid for 30 s. Laser etching was performed with Er, Cr:YSGG (2780 nm) laser using G6 tips and 600 μm diameter, 2.5 W or 3.5 W power outputs, pulse duration of 140 μs and a repetition rate of 20 Hz. Sealant was applied on the buccal surface followed by an incremental buildup with composite resin. Microtensile bond strength was assessed and compared among the five groups using one- and two-way ANOVA. Results: There was no statistical difference in the mean bond strength between groups except in Group 4 (9.66 MPa) (Group 1: 15.57 MPa; Group 2: 14.18 MPa; Group 3: 14.78 MPa; Group 5: 14.63 MPa). Conclusion: Pretreatment with 3.5 W Er, Cr:YSGG laser alone results in microtensile bond strengths similar to that produced by acid etching, indicating that enamel etching using 3.5 W Er, Cr:YSGG laser would result in the long-term success of pit and fissure sealants in primary teeth.
Efficacy and efficiency of papacarie versus conventional method in caries removal in primary teeth: An SEM study
(2020) AlHumaid, Jehan
Background: Chemomechanical methods such as Papacarie were developed as alternate dental caries removal methods to overcome major disadvantages of the conventional drilling technique. However, few studies have demonstrated the efficacy of Papacarie for caries removal using scanning electron microscope (SEM). Objectives: The purpose of this study was to compare the efficacy and efficiency of Papacarie and the conventional bur method in caries removal from primary teeth. Materials and Methods: In this in vitro study, 30 freshly extracted, human primary molars with dentinal caries were obtained from the outpatient clinics at the Dental Hospital of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. Each tooth was sectioned mesiodistally into two halves through the center of the lesion, and each half was randomly subjected to caries removal by Papacarie (Group I) and excavation using the conventional bur method (Group II). Time taken (efficiency) for removal of caries was noted using a stopwatch. Samples were then examined under SEM for presence of bacterial colonies (efficacy). For efficiency, data were analyzed using chi-square, and for efficacy, using t -test. Results: There was no significant difference in the presence of bacteria in both groups under SEM (Papacarie = 23.3%; conventional method = 16.7%; P = 0.52). However, significantly more time was taken for caries removal with Papacarie (mean = 351.56 s) than with the conventional bur method (mean = 158.41 s) ( P < 0.0001). Conclusion: Papacarie is as effective in removing dentinal bacteria as the conventional caries removal method but is less efficient, as the time taken for excavation was longer.
Impact of international collaboration on dentistry related papers published in Kingdom of Saudi Arabia
(2023) Hend Alshammary; Marwah Alamoudi; Ajmal Khan, Muhammad; Soban Q. Khan; Muhammad Ajmal Khan; Alamoudi, Marwah; Jehan AlHumaid; AlHumaid, Jehan
Objective This bibliographic analysis was designed to review all dental publications in the Kingdom of Saudi Arabia (KSA) and evaluate the effect of international collaboration on the impact of published articles. Methods The Web of Science (WOS) database was used to extract all related published articles in the KSA from 1982 to 2021. The keywords were connected using Boolean Operators to download related articles. Downloaded articles were screened according to the following inclusion criteria: collaboration journal category, journal discipline, number of citations, number of authors, and impact factor. After applying the inclusion criteria and excluding single-author articles, 5,689 documents were included in the final analysis. The chi-square test and two-independent samples t-test were used to determine the statistical significance between the variables. Results A significantly higher proportion of articles with international collaboration (51.4%) were published in dental journals than those published nationally (43.3%) or within the institutional level (41.8%) (P < 0.0001). In addition, the average number of citations (9.28 ± 23.8) ranged from 0 to 749, received by an article and the impact factor of the journal in which the article was published, significantly higher in the case of internationally collaborative work compared with national or within institutional collaboration (P < 0.0001). Conclusion International collaboration positively affected the impact factor, number of citations, and quartile rank of published articles. Moreover, the number of co-authors in different countries contributes to the international collaboration effect.
