Medications and Orthodontic Tooth Movement: What Accelerates and Diminishes Tooth Movement?

The biological aspect of orthodontic tooth movement is influenced by the magnitude and duration of the applied force. This initiates signaling cascades essential for bone remodeling, which involve activating various cell signaling pathways that enhance the metabolism of the periodontal ligament, leading to localized bone resorption and deposition. This process facilitates tooth movement on the pressure side and promotes healing on the tension side. The remodeling associated with orthodontic tooth movement is an inflammatory reaction involving mediators. Key components in this process include hormones, systemic influences, cyclic adenosine monophosphate, specific cytokines like interleukin 1, colony-stimulating factors, calcium, collagenase, and prostaglandins, all of which are essential for the biological adjustments necessary for tooth movement. Medications that influence molecular pathways critical for the homeostasis of periodontal tissues or that affect changes during orthodontic tooth movement and clastic cell regulation can potentially modulate tooth movement. With the recent increase in prescription medication use, it is essential for clinicians to be aware of medication consumption in prospective patients and understand its potential impact on orthodontic treatment. This review aimed to explore the effects of commonly prescribed medications on the rate of orthodontic tooth movement, thoroughly review the existing evidence on this topic, and identify potential areas for future research.

Skin anti-aging potential of Launaea procumbens extract: Antioxidant and enzyme inhibition activities supported by ADMET and molecular docking studies.

Aging is a natural process that occurs in all living organisms. Particularly, the skin embodies aging since it serves as a barrier between the body and its surroundings. Previously, we reported the wound healing effect of Launaea procumbens and identified compounds therein. The study aims to explore the skin anti-aging properties of the plant extract. To that effect, the antioxidant potential of L. procumbens methanolic extract (LPM) was assessed using two complementary DPPH and FRAP assays. The enzyme inhibitory effect of the extract on collagenase, elastase, hyaluronidase, and tyrosinase was evaluated to assess the direct skin anti-aging effects. Similarly, the anti-inflammatory activity was evaluated to explore the indirect anti-aging effects via the assessment of extract inhibitory effects on cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX). In addition, ADMET and molecular docking studies were performed to explore the interaction mechanisms of identified compounds in LPM with target enzymes. LPM demonstrated significant antioxidant activity in DPPH (IC50 = 29.08 µg/mL) and FRAP (1214.67 µM FeSO4/g extract) assays. Plant extract showed significant inhibition of collagenase, elastase, hyaluronidase, and tyrosinase (IC50 = 52.68, 43.76, 31.031, and 37.13 µg/mL, respectively). The extract demonstrated significant COX-2 and 5-LOX inhibition capacity with IC50 values of 8.635 and 10.851 µg/mL, respectively. The molecular docking study revealed the high potential of the identified compounds to bind to the active sites of enzymes crucially involved in the skin aging process. ADMET analysis of the compounds revealed their good absorption, distribution, and metabolism profiles, and they were found to be safe as well. Study findings suggest L. procumbens as a promising source for the development of natural skin anti-aging and antioxidant compounds. This, in turn, may facilitate its incorporation into cosmetic formulations after further investigation.

Assessing the Application and Effectiveness of Human Amniotic Membrane in the Management of Venous and Diabetic Ulcers: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

This study aimed to assess the efficacy of human amniotic membranes (HAM) in treating venous and diabetic ulcers, which often pose challenges in healing. A systematic review and meta-analysis were conducted, evaluating 10 relevant studies involving 633 participants. Findings revealed that HAM treatment significantly accelerated ulcer closure, demonstrating over 90% complete healing compared to standard care. Despite moderate heterogeneity among studies, the results strongly suggested the effectiveness and safety of HAM therapy for venous and diabetic leg ulcers. Further research with larger study cohorts is recommended to bolster the existing evidence supporting HAM in managing these challenging wounds.

Quantitative and qualitative 3D analysis of mandibular lingual concavities: Implications for dental implant planning in the posterior mandible.

OBJECTIVE: The purpose of this study is to investigate the type of ridge (degree of angulation of the lingual concavity) and the buccolingual dimensions in the area of the first and second molars in both genders of different ages and how this will affect implant placement in the posterior mandible. MATERIALS AND METHODS: This retrospective cross-sectional study comprised cone beam computed tomography images of 150 dental patients (75 males and 71 aged ≥30). The following were measured/reported: type (morphology) of the ridge (convex [C], parallel [P], or undercut [U]), buccolingual width at the base and the crest of the ridge, and ridge height. The concavity angle, depth, and length of the U-shaped ridge were measured too. RESULTS: The prevalence of type U ridge ranged from 32.7% in the first molar region to 62.7% in the second molar region. Almost all measurements and ridge type distributions were comparable amongst the age groups (p > .05). Very few significant differences were found when comparing #36 versus #37 and #46 versus #47 teeth, with no differences in the distribution of the ridge types (p > .05). Quite the inverse, all measurements were statistically different when comparing #36 versus #37 and #46 versus #47 teeth, and type U ridge was more frequent in second molar compared to the first molar regions, respectively (p < .05). Many measurements were statistically higher in females; the inverse was true for a few measurements (p < .05). Type U ridge in #36 and #37 was found more frequently among males (p < .001). In contrast, the ridge types in #37 and #47 were not statistically different gender-wise. CONCLUSIONS: The U type of ridge was more prevalent in the investigated population, encountered more frequently in the second molars generally and in the first molars of males than females. Most posterior mandibular measurements are similar age- and side-wise but seem different gender- and tooth-wise.

Cone-Beam Computed Tomography-Based Investigation of the Prevalence and Distribution of Pulp Stones and Their Relation to Local and Systemic Factors in the Makkah Population: A Cross-Sectional Study.

Objectives This study aimed to assess the prevalence and distribution of dental pulp stones and evaluated their possible associations with local and systemic factors in the Makkah population in Saudi Arabia. Materials and methods Archived cone-beam computed tomography (CBCT) images for 390 patients, from the electronic health records (EHR) in the Dental Teaching Hospital, Umm Al-Qura University, were used. Images were examined in all planes (coronal, sagittal, and axial) for a discrete radiopaque mass in the pulp of all teeth, in both arches. The teeth conditions (the presence of caries, restoration, the periodontal condition, and the presence of pulp stones) were recorded. Additional patient information, including age, gender, and medical condition, was obtained from the patients' archived files. The collected data were statistically analyzed using the Statistical Package for Social Sciences (SPSS) (IBM SPSS Statistics, Armonk, NY) software; a p-value of ≤ 0.05 is considered statistically significant. Results Pulp stone prevalence was 78.97% of the subjects (308 out of 390) and 15.92% of the examined teeth (1644 out of 10326). There were statistically significant differences regarding nationality (p=0.043) and age (p=0.023) but no significant difference between males and females (p=0.876), maxillary and mandibular teeth (p=0.392), and right and left sides (p=0.222) in pulp stone prevalence. Significant differences were found between pulp stone prevalence of sound versus and carious and restored teeth and between periodontally affected teeth and periodontally healthy teeth (p=0.031). Conclusion The prevalence of pulp stones in the Makkah population is high. A positive association was found between nationality, age, tooth restorations, caries, periodontal diseases, and pulp stone prevalence, but no correlation was found with patients' health or gender. The molars were the most affected teeth, while the incisors were the least.

Pediatricians' Awareness of Pediatric Psoriasis in the Makkah Region, Saudi Arabia.

Background Psoriasis is an autoimmune disease characterized by the typical appearance of red, thickened, scaly patches on the skin (plaques). These plaques can vary in size and distribution from person to person. In some individuals, it may affect small areas of skin, while in others, large areas covering their body may be involved. Patients with psoriasis might be identified by pediatricians before being seen by dermatologists, highlighting the need for pediatricians to be aware and knowledgeable about pediatric psoriasis. Objective To evaluate the knowledge and management of pediatric psoriasis among pediatricians and pediatric residents in the Makkah region, Saudi Arabia. Methods This was a cross-sectional study using a questionnaire targeted at pediatricians. It inquired about sociodemographic details, knowledge of psoriasis risk factors, diagnosis, management, comorbidity screening, and indications for consulting a dermatologist. The knowledge score cut-off was set at 60%, with scores below this threshold considered indicative of poor knowledge and scores above it reflecting good knowledge. Results A total of 139 participants completed the questionnaire; 103 (74.1%) were from Jeddah, 101 (72.7%) were pediatric residents, 118 (84.9%) were general pediatricians, and 18 (15.1%) were in subspecialties. About a third, 49 (35.3%), reported having seen a child with psoriasis. Most participants, 84 (60.4%), had a good knowledge level regarding psoriasis. The vast majority, 119 (85.6%), stated that topical therapies are the first-line treatment; 105 (75.5%) reported being confident in diagnosing psoriasis, and having previously seen a patient with psoriasis was associated with certainty in diagnosis (p-value=0.048); 82 (59%) referred patients to dermatologists. Physician position (p-value=0.049) and being in a general specialty (p-value=0.048) were associated with higher knowledge. Conclusion Overall, participants had good knowledge of pediatric psoriasis and its management. However, there is still a need for improvement.

Socio-Demographics of Initial Substance Use Exposure and Its Relation to Progression: A Cross-Sectional Study in Saudi Arabia.

INTRODUCTION: Empirical evidence on substance use in Saudi Arabia is lacking. This quantitative study is aimed at describing the socio-demographics of initial exposure to substance use and its relation to substance abuse progression. METHOD: A questionnaire about socio-demographics during initial exposure to substance use was completed by 379 participants. RESULTS: For most participants, the commencement of substance abuse occurred at the age range of 19‒23 years, and while in high school, they first started taking drugs with school friends. The two psychoactive substances most commonly taken for the first time were hashish and alcohol. The two main reasons for first drug exposure were teenage curiosity and joy-seeking. The chi-square test revealed statistically significant differences between substance abuse progression by sex, current age, father's education level, parent's marital status, and one's company in substance use. Female participants were more likely to continue taking drugs. CONCLUSION: Young people must be educated about the risks and consequences of substance use from early adolescence.

Impact of Asthma Education Program 2020-2021 on Asthma Control Among Bronchial Asthma Children in Madinah City, Saudi Arabia.

BACKGROUND: Asthma control among asthmatic children still remains suboptimal. Saudi literature are scarce in this context, and there is a paucity of reports that compare asthma control level pre- and post-education program directed to asthmatic patients and their parents. OBJECTIVES: The objective of this study was to assess the impact of asthma education and flu vaccination on asthma control in asthmatic children in Madinah region from 2020 to 2021, in terms of ED visits, hospitalization, pediatric intensive care unit (PICU) admission, and asthma control level. METHODS: A cross-sectional study was conducted at primary health care (PHC) centers in Al-Madinah City, Saudi Arabia. The study analyzed data from 804 asthmatic children patients from randomly selected six PHC centers. The data were collected by a valid structured questionnaire. The questionnaire included socio-demographic and clinical data. Child asthma symptoms control was examined by the Childhood Asthma Control Test (C-ACT) for children aged 5-12 years, and the Test for Respiratory and Asthma Control in Kids (TRACK) for children less than five years of age. The collected data were analyzed using the appropriate statistical tests. RESULTS: The mean age of the studied children was 6.1±3.0 (1-14 years), with 59.8% of them being males. There have been statistically significant reductions for asthmatic children in ED visits/month, hospitalization, and pediatric ICU admission/years in the post-education groups for all studied patients and patients

The Antifungal Efficacy of Pure Garlic, Onion, and Lemon Extracts Against Candida albicans.

INTRODUCTION: The oral cavity is considered to be one of the most intricate environments in the human body. It is known to harbor commensal microorganisms that do not cause diseases, such as Candida albicans, a yeast fungus that has a carriage rate that tends to increase with age. It is worth noting that C. albicans can be readily identified within the flora of the gastrointestinal tract in 80% of healthy patients. Traditional medicine has alternatively been shown to play a key role in various health amenities with a wide spectrum anti-microbial effect against various yeast molds. OBJECTIVES: To evaluate the antifungal efficacy of pure garlic, onion, and lemon juice extracts against C. albicans. Materials and methods: C. albicans (ATCC 10231) were sub-cultured in brain agar followed by anaerobic incubation for 48 hours at 37°C. Ten plates were used for each of the materials studied to evaluate their antifungal efficacy against C. albicans. The efficiency of commercially available fresh garlic, onion, and lemon was tested in isolation against C. albicans. One-way ANOVA and chi-square were used for comparison between the different materials. The inhibition zone was measured, and the level of statistical significance was set at ≤0.05. RESULTS: The diameter of inhibition zones has been measured along the vertical and horizontal axis. No inhibition zones were observed for the onion and lemon extracts used in this study whereas the garlic extract exhibited inhibition zones with altered sizes (4.89 ± 0.275). A highly significant difference was observed between groups (P = 0.000) and between garlic and the other materials (P = 0.000). CONCLUSIONS: Pure garlic showed a highly significant antifungal efficacy when compared to the onion and lemon juice extracts against C. albicans. Further studies are needed using different concentrations of onion, lemon, and lemon peel juice to confirm their antifungal efficacy in addition to their actual antimicrobial benefits.

Hyaluronic Acid: A New Approach for the Treatment of Gingival Recession-A Systematic Review.

This systematic review aimed to investigate the effectiveness of hyaluronic acid (HA) on the clinical treatment outcomes of patients with gingival recession. A systematic search was performed in PubMed, Cochrane Central Register of Controlled Trials, Embase, Scopus, and Google Scholar for studies up to 15 August 2022. Two reviewers separately selected the papers for eligibility after conducting a thorough search. The study includes randomized controlled clinical trials in which participants were given HA in addition to periodontal treatment surgical procedures. The changes following the treatment protocol were evaluated for complete and mean root coverage as a primary outcome and gingival recession gain as the secondary outcome. Three articles met the eligibility criteria out of 557 titles. In periodontal surgery, HA exhibited better results in complete root coverage and mean root coverage when compared to the control group. Gingival recession reduction, clinical attachment level, and keratinized tissue gain were significantly increased compared to the control groups. However, the comparison presented in the following study might show heterogeneity among the studies and risk of bias in general. Given the scope of this analysis, results suggest that adjunctive treatment with HA gel for root coverage could be clinically beneficial.

Effect of Luting Cement Film Thickness on the Pull-Out Bond Strength of Endodontic Post Systems.

Optimal bond strength between the prefabricated post/dowel to the surrounding dentin is essential. The present study aimed to analyze and compare the effect of three different cement film thicknesses on the pull-out bond strength of three different prefabricated post systems. Extracted natural teeth (N = 90) with similar root dimensions were acquired. Teeth were mounted in resin blocks, endodontically treated, sectioned at cemento-enamel junction, divided into three groups (A: Parapost Fiber Lux plus; B: 3M ESPE Relyx fiber post; and C: Parapost XP), and stored. Uniform post spaces were prepared for the groups (A and C: Length = 8 mm, Width = 1.5 mm; B: Length = 8 mm, Width = 1.6 mm). Each group (N = 30) was further subdivided into three subgroups (n = 10) based on the size (4, 5, and 6) of the post and cemented with resin cement (MultiLink-N, Ivoclar Vivadent). After thermocycling, the specimens were subjected to a pull-out test using a universal testing machine, and tensile force was recorded (MPa). Digital microscopic evaluations were performed for modes of failure. ANOVA and Tukey-HSD tests were used for statistics. Significant differences were observed for each tested material (p = 0.000). The lowest and highest bond strength values were recorded for Group C (Titanium post) and Group A (000), respectively. Multiple comparisons showed significance (p < 0.05) among all the groups, except for space 1 and space 2 (p = 0.316) for Group A. Most of the failures occurred within the cement-dentin and post-cement interface (Adhesive failures, 73.5%). An increase in the luting cement film thickness results in the decrease in pull-out bond strength of prefabricated posts luted with resin cement, irrespective of the type/material/shape of the post. The serrated fiber posts showed the highest pull-out bond strength compared to the smooth surfaced fiber posts or serrated metal posts. Increased pull-out bond strengths were observed when appropriate post space was created with the same sized drill as the post size.
