A Comparison of Salivary Mercury Levels in Children with Attention Deficit/Hyperactivity Disorder When Compared to Age-matched Controls: A Case-control Observational Study.

AIM: The aim of this study was to compare the level of mercury in the saliva of children with attention deficit/hyperactivity disorder (ADHD) as compared to age- and gender-matched controls in specific age groups. MATERIALS AND METHODS: A case-control observational study design was used. In school children with ADHD and outpatient dental clinics of a university dental hospital, the participants were schoolchildren diagnosed with ADHD studying in the first grade (6-7 years), sixth grade (12-13 years), and ninth grade (15-16 years) and were gender-matched to children without ADHD attending regular classes in school. Ninety children with ADHD comprised the test group while 90 children without ADHD comprised the control group. RESULTS: In this study, we found that children with ADHD had higher levels of salivary mercury than their age- and gender-matched counterparts; however, this difference was significant only in the 6-7 years of age group. The regression model showed a mild positive association between salivary mercury and ADHD; however, the association was not statistically significant. CONCLUSION: While there is some indication that salivary mercury may be higher in children with ADHD, there is insufficient evidence to establish a definite association between the two. CLINICAL SIGNIFICANCE: The study highlights the need to evaluate existing evidence on the role of mercury, especially salivary mercury, in ADHD.

Oral Health Status, Treatment Needs and Oral Health Related Quality of Life among Hearing Impaired Adults in Riyadh City, Saudi Arabia.

AIM: The primary objective was to determine the oral health status and treatment needs among hearing-impaired (HI) adults. Second, to assess the relationship between the oral health variables and oral health-related quality of life (OHRQoL) by using General Oral Health Assessment Index (GOHAI)-Ar questionnaire among HI adults in Riyadh city, Saudi Arabia. MATERIALS AND METHODS: A total of 146 HI adults between the age groups of 18-21, 22-25, and >25 years were included in the study. A convenient sampling technique was used to obtain the study sample. Oral health condition was recorded by using oral hygiene index-simplified (OHI-S), plaque index (PI), and gingival index (GI). The WHO methodology was used to record dental caries and treatment needs. The Saudi Arabian version of GOHAI-Ar questionnaire was used to gather information with regard to OHRQoL. A sign language expert communicated information between HI and investigator while answering the questionnaire. RESULTS: More than half of the HI had fair OHI-S (55.2%) and PI score (54.2%), while 60.1% of HI had moderate gingival inflammation. The prevalence of dental caries (82.2%) and treatment needs (85.6%) were found to be high. Mean oral hygiene scores between Saudi and non-Saudi nationals [(1.64) vs (1.12), p = 0.041] showed significant differences. Missing and filled teeth showed significant differences across different age groups (p = 0.000). The mean GOHAI-Ar was found to be low (14.44 ± 9.59). Spearman's test showed a significant positive correlation between the GOHAI-Ar score and the toothbrushing method (r = 0.164, p = 0.047). Toothbrushing time, oral hygiene material, last visit to dentist, OHI-S score, PI score, decayed, missing, and decayed missing filled teeth (DMFT) scores were negatively correlated with GOHAI-Ar. Speech was the main concern for the HI. CONCLUSION: There was a fair oral hygiene, moderate gingival inflammation, high caries experience, and treatment needs with low GOHAI-Ar scores indicating poor OHRQoL among HI.

Impact of the COVID-19 Pandemic on the Dental Preferences of Patients at Private University Hospitals in Riyadh, Saudi Arabia.

Studies that particularly look into how the pandemic has affected Saudi Arabian patients' dental preferences are scarce. The majority of the research done so far has focused on the pandemic's broad effects on oral health rather than the specific changes in patient preferences for dental care. Therefore, the primary goal of the study was to examine how patients at a private university dental hospital underwent dental procedures both before and after the pandemic. The study is a retrospective analysis of patient data from March 2019 to February 2022 obtained from electronic hospital records (Dentoplus). The data extracted information pertaining to the number of patients and their periodic visits. The data was examined via statistical tests. At 0.05, the significance level was chosen. According to the research, compared to non-lockdown times, lockdown times saw a considerable drop in the number of patients scheduling appointments. There was also a significant decrease in the number of first-time patients during lockdown periods. The study also revealed a significant increase in the number of cancelled appointments and patients who discontinued treatment during lockdown periods. The age and gender of the patients did not have a significant effect on these findings. The study's findings suggest that dental professionals need to be aware of these changes in patient behavior and adapt their services accordingly. Dental clinics may need to focus on promoting their services and ensuring that patients feel safe and comfortable seeking dental care during the pandemic.

Assessment of Salivary pH, Buffer Capacity, and Flow in COVID-19-Infected and Vaccinated Dental Patients.

Background The impact of COVID-19 infection and immunization on salivary gland function has not yet been fully understood. Therefore, a study to determine salivary pH (SP), salivary buffer capacity (SBC), and salivary flow (SF) in COVID-19-infected and immunized patients seeking dental care is necessary. Therefore, the main goal of this study was to evaluate saliva production at five minutes, SP, and salivary SBC in COVID-19-infected and vaccinated dental patients who were undergoing treatment at a private university dental hospital in Riyadh, Saudi Arabia. Methodology Dental students at Riyadh Elm University were included in this observational study, which involved dental patients. Based on Tawakkalna application records, patients were asked to provide their COVID-19 infection and vaccination status. Mean, standard deviation, and descriptive statistics of the frequency distribution were computed. Results The study included individuals aged 18 to 39 years old, with an average age of around 28.5 years old. The sample had slightly more males than females, but the difference was not significant. In terms of COVID-19 testing, most individuals had tested positive for the virus two or three times. The most common amount of unstimulated saliva produced was 3.5 mL, with most individuals producing between 2 and 3.5 mL of saliva. According to the observations, there were substantial variations between people who tested positive and negative for the COVID-19 virus in terms of SP and buffering capacity, suggesting that these factors could be possible indications of infection. Conclusions This study also emphasizes the value of evaluating several salivary factors to enhance diagnostic precision and the possibility of saliva-based testing as a non-invasive and affordable substitute for conventional diagnostic techniques in relation to oral issues. The study does, however, have several drawbacks, such as the limited sample size and the inability to be generalized to different populations.

In the field of dentistry, the implementation of blockchain holds promise for transforming dental practice and management. However, a comprehensive evaluation of the existing literature regarding the implementation of blockchain technology in dental practice is lacking. This systematic review aimed to assess the current evidence on the implementation of blockchain technology in dental practice and management. A systematic literature search was conducted using major databases to identify relevant studies. The search strategy included keywords related to blockchain technology and dentistry. The investigation was performed as per the PRISMA guidelines. Studies reporting on the implementation, adoption, and outcomes of blockchain technology in dental practice and management were included. Quality assessment and data extraction were performed following predefined criteria. The initial search yielded a multitude of articles, and after applying the inclusion and exclusion criteria, six studies were included in the systematic review. The studies explored various aspects of blockchain technology implementation in dental practice, including data security, interoperability, supply chain management, and patient consent management. Furthermore, the use of blockchain-based systems showed potential benefits in enhancing supply chain management efficiency and patient consent authentication. This systematic review provided insights into the current state of blockchain technology implementation in dental practice and management. The findings suggested that blockchain technology has the potential to enhance data security, privacy, and interoperability in dental practices. However, further research and real-world implementation studies are needed to fully understand the impact of blockchain technology on dental practice and to address the existing challenges.

Evaluating factors associated with fear and anxiety to dental treatment-A systematic review.

INTRODUCTION: Dental anxiety refers to a set of complex psychological issues bearing a significant impact in individual's lives reflecting in the form of dental visit avoidance, poor dental health status and decreases oral health related quality of life. Hence, it is imperative to consider those factors associated with dental anxiety so as to treat and promote better oral health. The review aimed to assess various factors associated with dental fear and anxiety. MATERIALS AND METHODS: Literature search was done from Pubmed and Google scholar search engines to identify publications which explored factors associated with dental fear and anxiety. RESULTS: Research evidence pointed a significant relationship of age, gender, maternal anxiety, previous dental experience, and number of siblings with dental fear and anxiety (DFA). CONCLUSION: Findings of the review clearly suggest that a better understanding of factors causing dental anxiety and phobia will help preventing dental avoidance and providing better care.

Relationship between type-I diabetes mellitus and oral health status and oral health-related quality of life among children of Saudi Arabia.

INTRODUCTION: The study was conducted to assess the impact of oral health status on the oral health-related quality of life (OHRQOL) of children between 12 and 15 years with type-1 diabetes mellitus (IDDM) in Saudi Arabia and compare these findings to age and gender matched medically fit children. MATERIALS AND METHOD: A total of 40 children aged between 12 and 15 years with (IDDM) group presenting to the pediatric endocrinology clinic of the KSMC, Riyadh were age and gender matched to a control group of children reporting for a routine dental checkup at the dental clinics of the REU. The oral health of all children was recorded using WHO examination criteria. Parental perception of the OHRQoL was recorded using the validated Arabic version of the short-form child oral health impact profile-short-form COHIP-19. The independent samples t-test was used to compare the DMFT, Gingival index, and COHIP19 domains of the two groups. RESULTS: Individuals with IDDM had higher Gingival Index and DMFT scores; however, the differences were not statistically significant. The IDDM group showed higher COHIP scores across all domains. However, the differences were only statistically significant for the oral health domain (P = 0.003). CONCLUSION: Children with IDDM had better oral health both in terms of dental caries and gingival status when compared to their age-matched controls. However, they had significantly higher oral health domains that suggest a poorer overall OHRQoL in children with IDDM.

Evaluation Distal Caries of the Second Molars in the Presence of Third Molars among Saudi Patients.

OBJECTIVES: To evaluate the prevalence of distal caries in second permanent molars in the presence of third molar among patients attending university dental clinics in Riyadh City, Kingdom of Saudi Arabia. MATERIALS AND METHODS: Clinical and radiographic data (orthopantomographs and right and left bite wings) from 313 patients attending Riyadh Elm University dental clinics, department of oral diagnosis were collected and analyzed for the presence of third molars and caries on the distal surface of the second molar. Descriptive statistics of frequency distribution, mean and standard deviation, and binary logistic regression analysis were applied to assess the association between distal surface caries on second molars and impaction status of the teeth. RESULTS: The mean decayed, missing, and filled teeth score of the study participants was found to be very high, that is, 23. The prevalence of caries affecting the distal aspect of the second molar was 48.6% (n = 609) in the population. The prevalence of distal caries was significantly high in patients with fully erupted wisdom teeth followed by vertical, horizontal, and mesial impacted third molars (P < 0.05). Wisdom teeth with mesioangular, vertical, and horizontal impactions showed significant association with distal caries of second molars below the contact point, whereas, fully erupted and vertically impacted wisdom teeth showed significant association with distal surface caries of second molars above contact point. Similarly, vertically impacted wisdom teeth were found to have significant association with caries of distal surface of second molars on noncontact areas (P < 0.05). CONCLUSION: This study showed that the distal surface of the second molars is at risk of caries in the presence of third molars. However, this risk depends on eruption status, type of angulation, and contact between third and second molars. All the preventive measures should be taken to avoid caries on distal surface of second molar.
