Project description:Excessive gingival display (EGD) is defined as more than 2 mm of gingiva display above the maxillary incisors at maximum smile. Various skeletal, dental, and soft tissue etiological factors for EGD have been suggested. This study assessed the effectiveness and stability of surgical (SX) and nonsurgical (NSX) interventions for correction of EGD through a systematic review and meta-analysis following PRISMA 2020 guidelines. An electronic search of Ovid MEDLINE, EMBASE, CENTRAL, Scopus, Web of Science, and LILACS was conducted (2010-2023). Results were expressed as mean change in gingival display using the random-effects model at 1, 3, 6, and 12-month follow-up. At 1 month, SX and NSX treatments yielded a comparable mean reduction of 3.50 mm (2.13-4.86) and 3.43 mm (2.67-4.19) in gingival display, respectively. However, by 6 months, NSX treatments showed a reduction of 0.51 mm compared to 2.86 mm with SX treatments. SX outcomes remained stable past 6 months, while NSX outcomes partially relapsed at 6 months and returned to baseline levels at 12 months. Notably, NSX treatments were more effective in cases with mild initial EGD, while SX treatments showed a better outcome in severe cases. To draw more robust conclusions regarding the treatment outcomes, future primary studies of greater rigor are required.

Project description:BackgroundSurgical guides have been proposed in an attempt to reach more predictable outcomes for esthetic crown lengthening. The objective of the present study was to evaluate the effectiveness of esthetic crown lengthening using 3D-printed surgical guides in the management of excessive gingival display due to altered passive eruption type 1B.Materials and methodsSixteen patients diagnosed with altered passive eruption type 1B, were divided into two groups. In the control group, the procedure was carried out conventionally, and in the study group, a dual surgical guide was used. The parameters of wound healing (swelling, color, probing depth, bleeding index, and plaque index), pain scores, gingival margin stability, and operating time were assessed at 1 week, 2 weeks, 3 months, and 6 months postoperatively.ResultsThere was no statistically significant difference in terms of wound healing, pain scores, and gingival margin stability between both groups at different time intervals (P = 1), however, there was a statistical difference between both groups in terms of operating time with the study group being significantly lower (P < 0.001).ConclusionDigitally assisted esthetic crown lengthening helps shorten the operating time and reduces the possibility of human errors during the measurements. This will be useful in helping practitioners achieve better results.Practical implicationsThe conventional method remains to be the gold standard. However, shorter operating time and lower margins for errors will help reduce costs as the chair side time is reduced as well as the possibility for a second surgery is lower. This will improve patient satisfaction as well.

Project description:PurposeThis study is aimed at synthesizing the available evidence regarding effectiveness of various modalities (combinations of LRS tasks) and comparison between each two modalities in terms of gingival display reduction, success rate, stability of the results, patient's satisfaction, and postoperative morbidity.Materials and methodsThe electronic databases including PubMed, Scopus, Web of Science Cochrane Library, Google Scholar databases, ClinicalTrials.gov, and WHO International Clinical Trial Registry Platform were searched up to 27th June 2020 regarding lip repositioning surgery. The modalities were defined as the combinations of the following tasks: frenectomy (yes/no), flap thickness (full/partial), and myotomy (yes/no). Meta-analyses were performed on gingival display change from baseline to months 3, 6, and 12 in each modalities using Stata (v.16).Results38 studies (including three clinical trials, two quasiexperimental studies, seven case series, and 26 case reports) met the criteria for final inclusion. The mean gingival display reduced from baseline to 6 months (WMD = -2.90, 95% CI: -4.85 to -0.95) in the patients undergoing the "frenectomy + full-thickness flap + myotomy" modality. This parameter decreased from baseline to 6 and 12 months, respectively (WMD = -2.68, 95% CI: -3.49 to -1.86; WMD = -2.52, 95% CI: -4.40 to -0.64), in patients undergoing the "frenectomy + partial-thickness flap + without myotomy" modality. In patients who undergone the "without frenectomy + partial-thickness flap + without myotomy" modality, gingival display reduced from baseline to 6 months (WMD = -3.22, 95% CI: -5.61 to -0.84). Almost 83% of patients with modality 1 had satisfaction.ConclusionsGingival display within the 6 months after LRS could be reduced with all modalities. Descriptively, the greatest reduction was observed in patients with the modality not including the frenulum.

Project description:Gingival recession is commonly associated with plaque-induced inflammation and calculus. A high frenal attachment is more important in gingival recession in the child-patient. A healthy child-patient with impeccable oral hygiene presented with localized gingival recession without plaque-induced inflammation which led to the exploration of other possible etiologies. Multiple factors appeared to be acting in consonance (Concomitant multiple etiologies [CME]). The factors were a high frenal attachment, traumatic overbite and bruxism induced by premature tooth contacts. Pedodontists and periodontists should rule out CME in cases of gingival recession in the child-patient.

Project description:The aim of this study is to assess whether the effect of gender on the excessive daytime sleepiness (EDS) is influenced by two confounders (age and hours of sleep per night). A cross-sectional study was conducted at King Abdulaziz Medical City-Riyadh (KAMC-R). A total of 2095 respondents answered a questionnaire that included questions regarding gender, age, hours of sleep per night, and daytime sleepiness using the Epworth Sleepiness Scale (ESS). The prevalence of EDS was 20.5% (females 22.2%, males 19.5%, p-value=0.136). The EDS did not differ between genders, age groups, or hours of sleep per night (<6 vs. ?6h). However, stratified statistical analysis shows that the prevalence of EDS did differ according to gender (25.3% in females, 19.0% in males, p-value=0.036) in respondents with shorter hours of sleep per night. EDS was strongly related to female gender and young age (ages?29years) in respondents with short hours of sleep. This study reveals that one out of five of the general Saudi population has EDS. The effect of gender on EDS appeared to be influenced by hours of sleep per night. High EDS strongly related to female gender with short hours of sleep.

Project description:BACKGROUND:Gingivitis is a site-specific inflammatory condition initiated by dental biofilm accumulation. The accumulation of dental plaque on the gingival margin triggers inflammatory effects that can become chronic. In addition to its local effect, gingival inflammation has recently been suggested to have an impact on general health. OBJECTIVE:Determine the prevalence of gingivitis and its relationship to oral hygiene practices in high school children in Saudi Arabia. DESIGN:Cross-sectional. SETTING:High schools from different regions in Saudi Arabia. PATIENTS AND METHODS:Periodontal examinations were conducted on a randomly selected sample of high school children between the ages of 15 and 19 years. Gingival and plaque indices, probing depth, clinical attachment level, oral hygiene practices and sociodemographic characteristics were recorded. Data were analyzed using descriptive statistics, chi-square and the independent t test. MAIN OUTCOME MEASURE:Prevalence of gingivitis as defined by mean gingival index. SAMPLE SIZE:2435 high school students. RESULTS:Twenty-one percent of the sample had slight gingivitis, 42.3% had moderate, and 1.8% had severe. Gender, toothbrushing, tongue brushing, plaque index, and the percentage of pocket depth (PD) ?4 mm showed a significant relationship with the severity of gingivitis. Almost 39.3% of females had a healthy periodontal status when compared to males (30.7%). Thirty-five percent (35.5%) of students who brushed their teeth had a healthy periodontium compared to 26.9% who did not brush. The mean plaque index was significantly higher in students with severe gingivitis when compared to students with healthy periodontium (2.4 vs. 0.79, respectively). CONCLUSION:Gingivitis prevalence was high compared with Western countries in a nationally representative sample of high school students in Saudi Arabia and was influenced by oral hygiene practices. LIMITATIONS:The half-mouth study design may underestimate disease prevalence. Data on oral hygiene practices was self-reported and may thus have been affected by social desirability bias. CONFLICT OF INTEREST:None.

Project description:Scar formation following skin injury can be a major psychosocial and physiological problem. However, the mechanisms of scar formation are still not completely understood. Previous studies have shown that wound healing in oral mucosa is faster, associates with a reduced inflammatory response and results to significantly reduced scar formation compared with skin wounds. In the present study, we hypothesized that oral mucosal fibroblasts from human gingiva are inherently distinct from fibroblasts from breast and abdominal skin, two areas prone to excessive scar formation, which may contribute to the preferential wound healing outcome in gingiva. To this end, we compared the phenotype of human gingival and skin fibroblasts cultured in in vivo-like three-dimensional (3D) cultures that mimic the cells' natural extracellular matrix (ECM) niche. To establish 3D cultures, five parallel fibroblast lines from human gingiva (GFBLs) and breast skin (SFBLs) were seeded in high density, and cultured for up to 21 days in serum and ascorbic acid containing medium to induce expression of wound-healing transcriptome and ECM deposition. Cell proliferation, morphology, phenotype and expression of wound healing and scar related genes were analyzed by real-time RT-PCR, Western blotting and immunocytochemical methods. The expression of a set of genes was also studied in three parallel lines of human abdominal SFBLs. Findings showed that GFBLs displayed morphologically distinct organization of the 3D cultures and proliferated faster than SFBLs. GFBLs expressed elevated levels of molecules involved in regulation of inflammation and ECM remodeling (MMPs) while SFBLs showed significantly higher expression of TGF-? signaling, ECM and myofibroblast and cell contractility-related genes. Thus, GFBLs display an inherent phenotype conducive for fast resolution of inflammation and ECM remodeling, characteristic for scar-free wound healing, while SFBLs have a profibrotic, scar-prone phenotype.

Project description:Background and purposeThe etiologies and frequencies of cerebellar ataxias vary between countries. Our primary aim was to determine the frequency of each diagnostic group of cerebellar ataxia patients in a Korean population.MethodsWe reviewed the medical records of patients who were being followed up between November 1994 and February 2016. We divided patients with cerebellar ataxias into familial and non-familial groups and analyzed the frequency of each etiology. Finally, we categorized patients into genetic, sporadic, secondary, and suspected genetic, but undetermined ataxia.ResultsA total of 820 patients were included in the study, among whom 136 (16.6%) familial patients and 684 (83.4%) non-familial cases were identified. Genetic diagnoses confirmed 98/136 (72%) familial and 72/684 (11%) nonfamilial patients. The overall etiologies of progressive ataxias comprised 170 (20.7%) genetic, 516 (62.9%) sporadic, 43 (5.2%) secondary, and 91 (11.1%) undetermined ataxia. The most common cause of ataxia was multiple-system atrophy (57.3%). In the genetic group, the most common etiology was spinocerebellar ataxia (152/170, 89.4%) and the most common subtype was spinocerebellar ataxia-3.38 of 136 familial and 53 of 684 sporadic cases (91/820, 11.1%) were undetermined ataxia.ConclusionsThis is the largest epidemiological study to analyze the frequencies of various cerebellar ataxias in a Korean population based on the large database of a tertiary hospital movement-disorders clinic in South Korea. These data would be helpful for clinicians in constructing diagnostic strategies and counseling for patients with cerebellar ataxias.

Project description:Unlike skin, oral gingiva do not scar in response to injury. The basis of this difference is likely to be revealed by comparing the responses of dermal and gingival fibroblasts to fibrogenic stimuli. Previously, we showed that, compared to dermal fibroblasts, gingival fibroblasts are less responsive to the potent pro-fibrotic cytokine TGF?, due to a reduced production of endothelin-1 (ET-1). In this report, we show that, compared to dermal fibroblasts, human gingival fibroblasts show reduced expression of pro-adhesive mRNAs and proteins including integrins ?2 and ?4 and focal adhesion kinase (FAK). Consistent with these observations, gingival fibroblasts are less able to adhere to and spread on both fibronectin and type I collagen. Moreover, the enhanced production of ET-1 mRNA and protein in dermal fibroblasts is reduced by the FAK/src inhibitor PP2. Given our previous observations suggesting that fibrotic fibroblasts display elevated adhesive properties, our data suggest that scarring potential may be based, at least in part, on differences in adhesive properties among fibroblasts resident in connective tissue. Controlling adhesive properties may be of benefit in controlling scarring in response to tissue injury.

Project description:Diet is a contributor to the pathogenesis of many non-communicable diseases. Among contributors to poor diet is high added sugar consumption, which is unfortunately on the rise nowadays. The recommended sugar intake by The American Heart Association (AHA) is 24g/day and 36g/day for women and men, respectively. The study's aim is to assess added sugar intake among adults in Saudi Arabia. A cross-sectional study design was used via an online survey among adults in Saudi Arabia using convenience sampling, and social media platforms were used to collect the data. The authors conducted descriptive statistics to present demographic variables using Chi-square χ2 tests for categorical and t-tests for continuous variables. All statistical tests used a 95% confidence interval with a two-sided P-value <0.05 as significance level. A total of 1163 respondents were included in the study. The study has shown an overall added sugar intake average of 73 g/day. There was a significant difference in means of overall added sugar intake across genders for the age group 18-30 and the age group >60. Equivalently, there was a statistically significant difference in means of added sugar intake food across gender (P-value 0.008). Females tended to consume more added sugar in their food than males. The highest consumption was in the Northern region (123.71 g/day), followed by the Southern region (98.52 g/day), the Western region (86.14 g/day), and lastly, the Central and Eastern regions (66.95 and 62.02 g/day, respectively). The total added sugar intake of added sugar is extremely high in Saudi Arabia. Poor dietary habits lead to many adverse health consequences, including obesity and diabetes. Healthcare providers and public health officials are highly encouraged to shed light on added sugar consumption and create opportunities to promote healthy dietary patterns. The Saudi population is recommended to abide by the added sugar dietary recommendations to avoid future chronic medical conditions.
