RESUMO
INTRODUCTION: This study aimed to compare the efficiency of temporary anchorage devices (TADs) and fixed functional appliances (FFAs) for mandibular molar protraction. METHODS: Orthodontic records of 1050 consecutively treated patients with molar protraction were screened. Thirty-six records (22 females and 14 males; mean age, 17.4 years) were divided into two groups: TAD (21 subjects with 25 edentulous spaces) and FFA (15 subjects with 24 edentulous spaces). The primary outcome measure was the efficiency of protraction [magnitude and time required for protraction (rate) and anchor loss (AL)]. The secondary outcomes involved measuring the type of tooth movement (TOTM), external apical root resorption (EARR), alveolar bone height change (ABHC), alveolar bone width change (ABWC) and appliance failure. RESULTS: The rate of tooth movement was significantly higher for FFAs (0.83 ± 0.35 mm/month) versus TADs (0.49 ± 0.2 mm/month) (P = .005). Total treatment duration was less for FFAs (34.78 ± 8.1 months) versus TADs (47.72 ± 13.94 months) (P = .002). TOTM was similar for both (P = .909). EARR was 1.42 ± 1.38 mm for TAD and 1.25 ± 0.88 mm for FFA (P = .81). ABHC increased in the FFA group (1.01 ± 3.62 mm) and decreased for the TAD group (0.68 ± 1.66 mm). ABWC increased for both TAD (1.81 ± 1.73 mm) and FFA (1.75 ± 1.35 mm). The failure rate was 50% for FFAs and 33% for TADs. CONCLUSIONS: Both systems provided translation of lower molars with comparable anchorage control. However, FFAs were more efficient than TADs for lower molar protraction.
RESUMO
BACKGROUND: Bell's palsy is a condition affecting cranial nerve VII that results in acute peripheral unilateral facial weakness or paralysis of unclear etiology. Corticosteroids are the primary therapy choice, because they improve outcomes. According to a recent study, prednisolone effectively treats Bell's palsy in the short and long term. This study aimed to assess the effectiveness and safety of Single-Dose Intravenous Methylprednisolone to Oral Prednisolone in treating Bell's palsy patients. METHODS: PRISMA statement guidelines were used to design and conduct this systemic review. MEDLINE, Cochrane Library, and EMBASE databases were used in our search. We conducted the database search in November 2022. RESULTS: Thirty-three publications were reviewed as a result of the literature review. Three studies were included in the meta-analysis after applying our criteria. 317 Bell's palsy patients were included in our study. Regarding complete recovery to grade 1 in 1 month, IV methylprednisolone was higher than oral prednisolone; (log OR = 0.52, 95% CI [0.08, 0.97], P = 0.022). However, at 3 months, the two groups had no significant difference. Patients with grade 4 Bell's palsy were more likely to fully recover to grade 1 in 1 month with IV methylprednisolone than with oral prednisolone (log OR = 0.73, 95% CI [0.19, 1.26], P = 0.008), but not for patients with grade 3 or grade 2 Bell's palsy. CONCLUSION: This study shows evidence that patients with Bell's palsy can fully recover to grade 1 in 1 month when IV methylprednisolone is used instead of oral prednisolone. At 3 months, however, there was no discernible difference between the two treatments. Within 3 days of the onset of symptoms, IV methylprednisolone treatment can be started, which may help patients recover fully to grade 1 in 1 month. However, administering IV methylprednisolone may not always have long-term advantages compared to oral prednisolone.

OBJECTIVE: This retrospective two-centre study aimed to evaluate the occlusal outcomes in patients undergoing orthognathic surgery with clear aligners. METHODS: A retrospective chart review and occlusal outcomes for 15 patients (10 females and five males) with different types of dentofacial deformities in the anteroposterior, vertical and transverse dimensions, who underwent orthognathic surgery in conjunction with clear aligners were evaluated. Weighed Peer Assessment Rating (PAR) index scores of the pre-treatment and post-treatment digital models were used to assess initial complexity, final occlusal outcomes and degree of improvement with surgery and clear aligners. RESULTS: The mean post-treatment PAR score was 3.5 ± 2.54, which was a statistically significant improvement from the pre-treatment PAR score of 27.63 ± 12.09, an 87% improvement was achieved. All subcategories of the PAR index showed statistically significant improvement except for midline assessment component. CONCLUSIONS: Occlusal outcomes with aligners showed great improvement as indicated with the PAR index scores. Orthognathic surgical cases can be treated efficiently with aligners and future studies should compare occlusal outcomes between orthognathic surgical patients treated with clear aligners and those treated with fixed appliances.

OBJECTIVE: To assess the effect of clear aligners on the speech of patients undergoing orthodontic therapy through a systematic review of the literature. Search methods and selection criteria: The protocol of this systematic review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) CRD42021278694. An electronic search of the Scopus, Embase, Pubmed, and Web of Science databases was done for papers published between January 2000 till September 2021. Studies that evaluated speech difficulties in patients undergoing orthodontic treatment with clear aligners using objective and subjective analyses were included. The evaluated primary outcome was speech difficulties. Secondary outcomes were time to adaptation and recovery from speech difficulties. Study quality was assessed based on the Cochrane Handbook for Systematic Reviews of Interventions Handbook guidelines and ROBINS-I tool. RESULTS: Two hundred and eighty-three articles were screened to identify seven studies (n = 332 patients) that assessed speech difficulty with aligners, of which two were randomized trials. Meta-analysis was not performed due to the heterogeneity in the study designs. Five studies compared speech difficulty with aligners to fixed appliances. Two studies showed a moderate risk of bias and five studies had a serious risk of bias. Level of evidence was downgraded to low due to the methodological insufficiencies and risk of bias in the studies. All seven studies reported that aligners could influence the clarity and delivery of speech, similar to fixed appliances. Various phonemes were affected including /s/,/z/,/zh/,/sh/,/th/,/ch/ on wearing aligners. Errors in articulation of consonants and sibilants were noted with lisping and speech impairment. These speech difficulties were temporary and most patients recovered in 7-14 days while few patients took 30-60 days to recover. CONCLUSION: The likelihood of speech difficulties appears high with clear aligners. However, patients adapt quickly and speech returns to normal. The results of this review must be interpreted with caution and more well-designed randomized trials examining long-term effects of aligners on speech are indicated. CLINICAL SIGNIFICANCE: Orthodontists should counsel patients opting for clear aligner treatment of the potential transient speech difficulties. REGISTRATION: The protocol for this systematic review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) CRD42021278694.

AIM: This retrospective study aimed to compare and evaluate the pattern of maxillary canine impaction and its association with other anomalies using cone-beam computed tomography (CBCT). METHODS: A total of 59 CBCT records of patients (ages 12 and up) were divided into two groups: A total of 35 subjects with unilateral canine impactions and 24 subjects with bilateral canine impactions. The CBCT data were analyzed for the measurement of qualitative and quantitative variables. RESULTS: In unilateral canine impaction, the mesiodistal (MD) width of the central incisors and the nasal cavity (NC) width were wider (p < 0.05). The canine-palatal plane (U3-PP) distance was significantly longer in bilateral canine impaction (p < 0.05). The distance of the impacted canines from the palatal and mid-sagittal planes, the anterior dental arch width, and the maxillary skeletal width changed significantly with the position of the impacted canines (p < 0.05). Males had 0.185 odds of presenting with a bilateral canine impaction as compared to females (p = 0.025). The odds of having bilateral canine impaction with a longer canine-midsagittal plane (U3-MSP) distance was 1.30 (p = 0.003). CONCLUSION: The findings indicate a gender predilection with females showing a greater prevalence of bilateral canine impaction. Supernumerary teeth were associated with unilateral impacted canines and lower canine impaction with bilaterally impacted canines. CLINICAL SIGNIFICANCE: Anomalies in the form of the maxillary central and lateral incisors, distance from the maxillary canine to the palatal plane and the mid-sagittal plane, NC width, maxillary skeletal width, and gender, are the best discriminating parameters between unilateral and bilateral canine impactions.

BACKGROUND Early pre-eruptive inclination changes of the first premolar (FP) and its associative changes with canine (C) inclination are important to predict canine impaction. This study aimed to evaluate the mesiodistal root angulation of permanent lateral incisors (LI), canines, and first molars by orthopantomogram dental imaging in 296 children ages 6-14 years at a single center in India. MATERIAL AND METHODS The total number of participants was 296, with equal numbers of boys and girls divided into 4 age groups: 6-8 years, 8-10 years, 10-12 years, and 12-14 years. Angles between lateral incisor, erupting canine, and first pre-premolar with midline were measured on an orthopantomogram (dental imaging which includes all the teeth with TMJ). The angle between the erupting C with LI and erupting C with FP was measured. Pearson's correlation was also evaluated between the movement of the erupting canine with lateral incisor and erupting canine with erupting first premolar. RESULTS There was a significant difference in the angular values of different age groups (P≤0.05). The movements between LI, C, and FP were moderately correlated boys and girls aged 6-12 years. CONCLUSIONS The findings from this study showed that in boys and girls aged 6-14 years, eruption of the upper canine tooth was synchronized with eruption of the LI and FP.

BACKGROUND In this study, we aimed to evaluate orthodontic mini-implant placement in the maxillary anterior alveolar region by cone beam computed tomography (CBCT) in 15 patients at a single center in South India. MATERIAL AND METHODS A total of 15 CBCT scans of orthodontic patients after completion of leveling and aligning stage were included. The thickness of labial alveolar bone, labio-palatal bone, and inter-radicular distance between the maxillary central incisors (U1-U1), maxillary central and lateral incisor (U1-U2), and maxillary lateral incisor and canine (U2-U3) at vertical levels 4 mm, 6 mm, and 8 mm above the interdental cementoenamel junction were measured. Descriptive statistics, ANOVA, and Tukey post hoc tests were done to assess the differences among the groups. An independent t test was done to analyze differences by sex. RESULTS The thickness of cortical bone in the labial region was higher in the U2-U3 site than in the U1-U1 site, at a height of 4 mm. Also, there was a significant difference between 4 mm and 8 mm heights in the U2-U3 region. No significant difference was noted in bone dimensions among men and women and in the labio-palatal bone thickness among the different sites. The inter-radicular distance was the highest between the U2-U3 site, while it was the lowest in the U1-U2 site. CONCLUSIONS The findings from this center showed that when CBCT was used to evaluate orthodontic mini-implant placement in the maxillary anterior alveolar region, the U2-U3 and U1-U1 locations at heights between 6 mm to 8 mm apical to the interdental cementoenamel junction were optimal for placement of the mini-implants.

INTRODUCTION: The purpose of the study is to determine reliability of true horizontal (TH) plane with Frankfort horizontal (FH) plane in cephalometric measurements. MATERIALS AND METHODS: One hundred lateral cephalograms were collected and traced using FACAD software, all cephalometric measurements which included FH plane as reference planes were used in this study. Cephalometric tracing was done with FH plane as reference plane and another set of measurements with TH plane as reference plane was done. Statistical tests were done using independent sample t-test (p <0.05). RESULTS: Results of an independent t-test revealed a statistically insignificant difference that was observed for all the parameters assessed (p <0.05). Both angular and linear measurements showed an insignificant difference between FH and TH. CONCLUSION: Within the limitations of the study, the results show that the FH plane is closest and as reliable as the TH plane. The variation of FH was least for all the parameters assessed.

Fasting Ramadan is known to influence patients' medication adherence. Data on patients' behavior to oral anticoagulant (OAC) drug intake during Ramadan is missing. We aimed to determine patient-guided modifications of OAC medication regimen during Ramadan and to evaluate its consequences. A multicenter cross-sectional study conducted in Saudi Arabia. Data were collected shortly after Ramadan 2019. Participants were patients who fasted Ramadan and who were on long-term anticoagulation. Patient-guided medication changes during Ramadan in comparison to the regular intake schedule before Ramadan were recorded. Modification behavior was compared between twice daily (BID) and once daily (QD) treatment regimens. Rates of hospital admission during Ramadan were determined. We included 808 patients. During Ramadan, 53.1% modified their intake schedule (31.1% adjusted intake time, 13.2% skipped intakes, 2.2% took double dosing). A higher frequency of patient-guided modification was observed in patients on BID regimen compared to QD regimen. During Ramadan, 11.3% of patients were admitted to hospital. Patient-guided modification was a strong predictor for hospital admission. Patient-guided modification of OAC intake during Ramadan is common, particularly in patients on BID regimen. It increases the risk of hospital admission during Ramadan. Planning of OAC intake during Ramadan and patient education on the risk of low adherence are advisable.

AIM: The trial was focused on assessing the effect of Denosumab in preventing anchorage loss during en-masse anterior retraction and evaluating its effect on the retraction. MATERIALS AND METHODS: This was a split-mouth randomized controlled trial. Ten subjects were randomly allocated with equal probability for Denosumab and control interventions in the contralateral quadrants using computer-generated randomization sequence. During the start of retraction, Denosumab (5 mg/0.2 mL) and injectable sterile water were administered locally on the intervention and control sides, respectively. Lateral cephalograms taken during the start of retraction and later in the 3rd and 6th months into retraction were used to evaluate anchorage loss and retraction. Independent sample t-test and Mann-Whitney U test compared anchorage loss and retraction between the two groups in the maxilla and mandible. Paired t-test and Wilcoxon signed-rank test assessed the anchorage loss and retraction during the first and the second 3 months of retraction. RESULTS: In the maxilla, Denosumab was effective in preventing anchorage loss with a p-value of 0.001 whereas it was not effective in the mandible (p-value-0.172). A significant reduction in anchorage loss was observed with Denosumab in the second 3 months of retraction compared to the first 3 months. There was no significant difference in the retraction among both groups. CONCLUSION: Denosumab was effective in minimizing the anchorage loss in the maxilla without affecting the anterior retraction. CLINICAL SIGNIFICANCE: Denosumab can be effectively used for reinforcing anchorage in the maxilla during en-masse anterior retraction.

BACKGROUND: The purpose of patient safety is to prevent harm occurring in the healthcare system. Patient safety is improved by the use of a reporting system in which healthcare workers can document and learn from incidents, and thus prevent potential medical errors. The present study aimed to determine patient safety challenges facing clinicians (physicians and nurses) in emergency medicine and to assess barriers to using e-OVR (electronic occurrence variance reporting). METHODS: This cross-sectional study involved physicians and nurses in the emergency department (ED) at King Khalid University Hospital (KKUH) in Riyadh, Saudi Arabia. Using convenience sampling, a self-administered questionnaire was distributed to 294 clinicians working in the ED. The questionnaire consisted of items pertaining to patient safety and e-OVR usability. Data were analyzed using frequencies, means, and percentages, and the chi-square test was used for comparison. RESULTS: A total of 197 participants completed the questionnaire (67% response rate) of which 48 were physicians (24%) and 149 nurses (76%). Only 39% of participants thought that there was enough staff to handle work in the ED. Roughly half (48%) of participants spoke up when something negatively affected patient safety, and 61% admitted that they sometimes missed important patient care information during shift changes. Two-thirds (66%) of the participants reported experiencing violence. Regarding e-OVR, 31% of participants found reporting to be time consuming. Most (85%) participants agreed that e-OVR training regarding knowledge and skills was sufficient. Physicians reported lower knowledge levels regarding how to access (46%) and how to use (44%) e-OVR compared to nurses (98 and 95%, respectively; p < 0.01). Less than a quarter of the staff did not receive timely feedback after reporting. Regarding overall satisfaction with e-OVR, only 25% of physicians were generally satisfied compared to nearly half (52%) of nurses. CONCLUSION: Although patient safety is well emphasized in clinical practice, especially in the ED, many factors hinder patient safety. More awareness is needed to eliminate violence and to emphasize the needs of additional staff in the ED. Electronic reporting and documentation of incidents should be well supported by continuous staff training, help, and feedback.

Hyperglycemia is frequently observed in adults with acute asthma. We aimed to assess the frequency of hyperglycemia and its relation to outcomes in children admitted with acute asthma. In this retrospective study, we reviewed medical records of non-diabetic 166 children (66 girls) with the mean age of 5.4 ± 2.6 years (range of 2-12 years), who were hospitalized with acute asthma between January 2012 through December 2014. Data pertaining to demographics, vital signs, oxygen saturation, serum blood glucose level, electrolytes, blood gases, and admission were collected. Children with other chronic conditions were excluded. The findings were that hyperglycemia (blood glucose ≥ 11.1 mmol/l) was observed in 38.6% of children. The median baseline blood glucose (IQR) was 9.8 mmol/l (7.2-13.3 mmol/l). Blood glucose level was associated with the length of hospitalization, with a median extension of 1.8 days, but was inversely associated with the serum potassium and bicarbonate levels. There were no associations between baseline blood glucose and age, gender, baseline respiratory rate, oxygen saturation, or intensive care admission. Hyperglycemia resolved spontaneously in all affected children. We conclude that hyperglycemia is common in children hospitalized with acute asthma. Hyperglycemia could be considered as a marker of a longer hospital stay.

Preterm birth remains a significant global health concern as it can lead to various health complications and long-term developmental challenges. Early nutrition intervention plays a crucial role in optimizing the growth, development, and overall health outcomes of premature infants. This review aims to summarize and analyze the existing literature regarding the effect of early nutrition interventions on premature babies. A comprehensive search was conducted through various electronic databases, including PubMed, Scopus, and Google Scholar, focusing on nutrition interventions specifically targeting premature infants. The review highlights the benefits of early nutrition interventions, including enteral and parenteral feeding, human milk, and the provision of specific nutrients. These interventions have been shown to enhance growth rates, promote neurodevelopmental outcomes, reduce the incidence and severity of retinopathy of prematurity (ROP), reduce the risk of infection, and improve overall morbidity and mortality rates in premature babies. Overall, the findings from this review suggest that early nutrition interventions have a positive impact on the health and developmental outcomes of premature babies. However, further research is required to determine the optimal approaches, optimal timing, and long-term effects of various interventions. Collaboration between healthcare providers, researchers, and families is crucial in implementing evidence-based nutrition practices and supporting the growth and development of premature infants.
RESUMO
BACKGROUND: Multiple myeloma (MM) is the second-most common cancer among hematological malignancies. Patients with active disease may experience several comorbidities, including renal insufficiency and asthma, which may lead to treatment failure. The treatment of relapsed or refractory MM (RRMM) has been associated with multiple factors, causing a decline in progression-free survival as well as overall survival with subsequent lines of therapy. Data about the characteristics of this group of patients in the Greater Gulf region are lacking. OBJECTIVE: The primary objective of this study is to describe the disease characteristics and various treatment approaches or regimens used in the management of patients with RRMM in the Greater Gulf region. METHODS: We will conduct a regional, retrospective study collecting real-world and epidemiological data on patients with MM in countries of the Greater Gulf region. Medical records will be used to obtain the required data. Around 150 to 170 patients' records are planned to be retrospectively reviewed over 6 months without any cross-sectional or prospective intervention. Cases will be collected from Saudi Arabia, the United Arab Emirates, Kuwait, Oman, and Qatar. Descriptive as well as analytical statistics will be performed on the extracted data. The calculated sample size will allow us to estimate the percentages of RRMM cases with acceptable precision while complying with the challenges in light of data scarcity. We will obtain a comprehensive description of the demographic profile of patients with MM; treatment outcomes; the proportion of patients with MM with renal impairment and asthma, chronic obstructive pulmonary disease, or both at the time of diagnosis and any subsequent point; and data related to treatment lines, regimens, and MM-associated morbidities. RESULTS: Patient medical records were reviewed between June 2022 and January 2023 for eligibility and data extraction. A total of 148 patients were eligible for study inclusion, of whom 64.2% (n=95) were male and 35.8% (n=53) were female. The study is currently in its final stages of data analysis. The final manuscript is expected to be published in 2024. CONCLUSIONS: Although MM is a predominant hematological disease, data on its prevalence and patients' characteristics in the Greater Gulf region are scarce. Therefore, this study will give us real-world insights into disease characteristics and various management approaches of patients with MM in the Greater Gulf region.

RESUMO
In Saudi Arabia, the evaluation of healthcare institutions' performance and efficiency is gaining prominence to ensure effective resource utilization. This study aims to assess the efficiency of government hospitals in Saudi Arabia using the case mix index (CMI) approach. Comprehensive data from 67 MoH hospitals were collected and analyzed. The CMI was calculated by assigning weights to different patient groups based on case complexity and resource requirements, facilitating comparisons of hospital performance in terms of resource utilization and patient outcomes. The findings reveal variations in the CMI across hospitals in relation to size and type. The average CMI was 1.26, with the highest recorded at 1.67 and the lowest at 1.02. Medical cities demonstrated the highest CMI (1.47), followed by specialized hospitals (1.32), and general hospitals (1.21). The study highlights opportunities for enhancing productivity and efficiency, particularly in hospitals with lower CMI, by benchmarking against peer institutions with similar capacities and patient case mix. These findings have significant implications for hospital operations and resource allocation policies, supporting ongoing efforts to improve the efficiency of government hospitals in Saudi Arabia. By incorporating these insights into healthcare strategies, policymakers can work towards enhancing the overall performance and effectiveness of the healthcare system.
RESUMO
Background: Worldwide, carpal tunnel syndrome (CTS) is the most common peripheral neuropathy due to compression. A minimally invasive endoscopic carpal tunnel release (ECTR) procedure is available to treat this condition. This study aims to identify and compare the different types of anesthesia in ECTR, particularly in terms of functional outcomes, patient satisfaction, and operative time. Methods: PRISMA guideline was used to design and conduct this systematic review. MEDLINE, Cochrane, and EMBASE databases were searched systematically from inception to May 2022. For the search, MeSH terms such as ECTR, general anesthesia, local anesthesia (LA), and regional anesthesia were used. Results: As a result of reviewing the literature, 198 publications were reviewed. After implanting our criteria, 12 studies were included. We included 14589 patients who underwent ECTR. LA has a higher satisfaction rate and a shorter operative time than general anesthesia. LA had a mean operative time of 20.1 min, compared to 45 min and 51 min for regional anesthesia and general anesthesia. The number of patients with postoperative ECTR surgical complications was 2.7% (95%CI). After ECTR with LA, 95% of patients are back to their daily routine within six months. Conclusion: All the reported methods were effective, with LA being the most commonly used. Furthermore, it showed a shorter operative time and a higher satisfaction rate than other types of anesthesia. Due to the heterogeneity of the data, we recommend future randomized controlled trials to highlight the differences in anesthesia types used in ETCR. Level of evidence: III, risk/prognostic study.
RESUMO
Background: There are few sports-specific knee functional scales in the Arabic language. The Knee Outcome Survey-Sports Activities Scale (KOS-SAS) is a validated sports-specific patient-reported outcome measure that assesses knee function in an athletic population. Purpose: To provide a validated Arabic version of the KOS-SAS (KOS-SAS-Ar) while achieving cross-cultural adaptation for use in an Arabic-speaking population with sports-related knee disorders. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: There were 2 independent translators who conducted a forward translation of the KOS-SAS, followed by a backward translation by different translators. Subsequently, researchers and expert invitees judged the conceptual content and cultural adaptations of the final translation. A total of 276 patients completed the KOS-SAS-Ar as well as the International Knee Documentation Committee (IKDC) subjective assessment of knee function and a visual analog scale (VAS) for pain. Statistical analysis was performed for test-retest reliability, convergent validity, construct validity, and factor analysis. Results: The test-retest reliability of the KOS-SAS-Ar was high (r = 0.9). The items of the KOS-SAS-Ar had statistically significant internal consistency, with a Cronbach alpha of .924 (P < .0001). The KOS-SAS-Ar Symptoms subscore correlated with the VAS pain score (P < .0001), and the KOS-SAS-Ar Functional Limitations subscore correlated with the IKDC subjective score (P < .0001). The construct validity of the KOS-SAS-Ar was satisfactory (Kaiser-Meyer-Olkin value = 0.868; Bartlett test: P < .0001). Factor analysis showed a statistical correlation among the 11 items of the KOS-SAS-Ar. Conclusion: The KOS-SAS-Ar demonstrated favorable reliability and validity, and it appears to be a suitable tool for Arabic-speaking patients with sports-related knee conditions.
RESUMO
Primary systemic vasculitis can present with a wide spectrum of manifestations ranging from systemic non-specific features such as fever, malaise, arthralgia and myalgia to specific organ damage. We describe two cases of cholesterol embolisation syndrome and Kaposi sarcoma mimicking primary systemic vasculitis, both of which were characterised by features such as livedo reticularis, blue toe syndrome, a brown purpuric skin rash and positive perinuclear anti-neutrophil cytoplasmic antibodies associated with Kaposi sarcoma. Establishing the right diagnosis was challenging and thus this report aimed to highlight the possible ways to distinguish them from primary systemic vasculitis.

This study compared tooth color and enamel and dentinal thickness between orthodontically treated and untreated individuals. (1) Methods: A matched case-control study was conducted. The sample included 26 patients who had received orthodontic treatment and 31 matched controls. The color assessment was performed subjectively using the VITA 3D-Master (VM) shade guide and objectively using the VITA Easyshade (VE) spectrophotometer. Differences in L*, a*, and b* (lightness, red/green, and blue/yellow) were calculated. The color change was evaluated using ΔE*ab and the whiteness index (WID). Tooth structure thickness (labiolingual, labial enamel, and labial dentin) was evaluated using cone-beam computerized tomography. The correlations between overall tooth color and tooth structure thickness were evaluated. (2) Results: A total of 228 teeth were evaluated. Color assessment using VM showed significant differences between orthodontically treated and untreated teeth (p < 0.001), while VE revealed no significant differences. Both groups showed no difference in tooth enamel and dentinal thickness. Significant differences in tooth color (p < 0.05) were observed between genders. Both VM and VE showed weak to moderate correlations with tooth color and enamel and dentinal thickness (p < 0.05). (3) Conclusions: Orthodontic treatment may demonstrate visually perceptible but acceptable and clinically undetectable tooth color alteration.
