Objective: The absence of a guideline to refer to developing malocclusions appropriately, may be a contributing factor to the inadequacy of timely interceptive orthodontics provision. This study aimed to develop and validate a new orthodontic grading and referral index to be used by dental frontliners to prioritize the orthodontic referral of developing malocclusion in children based on its severity. Methods: A cross-sectional study involving clinical assessment with 413 schoolchildren aged between 8.1 and 11.9 years was conducted in 2018. All the presenting malocclusion was listed and graded based on a few dental guidelines to produce the draft index. The validity and reliability of the draft index were tested using twenty study models. Face and content validation was carried out using the content validation index and Modified Kappa Statistics. Results: Fourteen dental and occlusal anomalies were identified as components of malocclusion and three grades of referral (monitor, standard, urgent) were included in the final index. The scale-level content validity index average value of 0.86 and 0.87 was obtained for content and face validation, respectively. There was moderate to excellent agreement in the Modified Kappa Statistics for both validations. Excellent inter- and intra-assessor agreement was obtained. The new index displayed valid and reliable scores. Conclusions: The Index for Interceptive Orthodontics Referral was developed and validated for the dental frontliners to identify and prioritize the developing malocclusion in children based on its severity and refer for orthodontic consultation to increase the possibility for interceptive orthodontics.

This study aimed to compare the disinfectant ability of chlorhexidine (CHX) gel and sodium hypochlorite (NaOCl). Systematic searches were conducted from inception until December 8th, 2022 (MEDLINE/PubMed, Cochrane Library, Web of Science, Scopus, Embase, and Grey Literature databases). Only randomized clinical trials were included. The revised Cochrane risk of bias tools for randomized trials were used to assess the quality of studies. Meta-analyses were performed. The overall quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation tool. Six studies were included. Five had a low risk of bias and 1 had some concerns. Three studies assessed bacterial reduction. Two were included in the meta-analysis for bacterial reduction (mean difference, 75.03 [confidence interval, CI, -271.15, 421.22], p = 0.67; I² = 74%); and 3 in the meta-analysis for cultivable bacteria after chemomechanical preparation (odds ratio, 1.03 [CI, 0.20, 5.31], P = 0.98; I² = 49%). Five studies assessed endotoxin reduction. Three were included in a meta-analysis (mean difference, 20.59 [CI, -36.41, 77.59], p = 0.48; I² = 74%). There seems to be no difference in the disinfectant ability of CHX gel and NaOCl, but further research is necessary.

Objective: Cerebral palsy (CP) is a neurodevelopment disorder attributed to an insult or injury to the developing brain with abnormalities in muscular tone, movement and motor skill. Improvement in quality of life and ameliorating symptoms can be achieved. Therefore, this case report details a distinctive approach to treating a 5-year-old male child with quadriplegic spastic cerebral palsy utilizing Unani treatment modalities. Methods: The treatment regimen commenced with 'Habb Ayarij for constipation followed by Sharbat Ustukhuddus administered orally. Notably, Sharbat Ustukhuddus was combined with Melia Azedarach L. leaves vapour bath. Subsequently, Roghan Babunna douche was performed followed by Dalk Layyin andcontinued until symptomatic improvement was observed. Majun Falasfa, Khamira Marwareed and Khameera Gauzaban were administered for 30 days. The therapeutic outcome included anthropometrical measurements, developmental milestones, spasm/reflex scale, and muscle power grading. Results and conclusion: Over the course of a 2-year follow-up, several clinical findings emerged. These included notable improvements in anthropometric measurements, developmental milestones such as improved head control and sitting ability, and a reduction in spasticity of the upper limbs, along with decreased muscle spasms. The therapeutic outcome of this individualized and holistic approach is potentially due to the multifaceted properties of medicinal plants (Musakkin wa Muharrik wa Muqawwi-i- A'sab wa Dimāgh, Munawwim, Dafi-i-Tashannuj, Muqawwi-i-Qalb-i-Ruh). Furthermore, the use of Dalk and Naṭūl was instrumental in providing nourishment to musculoskeletal cells and initiating intracellular signaling cascades. While these findings are encouraging, further research in the form of case series andrandomized controlled trials is warranted to validate the efficacy of this unique holistic approach.

This review aimed to answer the following question "Does photobiomodulation treatment of the root surface decrease the occurrence of root resorption in reimplanted teeth?" Electronic searches were performed in the MEDLINE/PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Grey Literature Report databases. Risk of bias was evaluated using SYRCLE Risk of Bias tool. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool was used to assess the certainty of evidence. In total, 6 studies were included. Five studies reported a reduced occurrence of root resorption in teeth that received photobiomodulation treatment of the root surface prior to replantation. Only 1 study reported contradictory results. The photobiomodulation parameters varied widely among studies. GRADE assessment showed a low certainty of evidence. It can be inferred that photobiomodulation treatment of the root surface prior to replantation of teeth can reduce the occurrence of root resorption. Nonetheless, further clinical studies are needed.

Purpose: Appropriate scoring systems can help classify and treat polytrauma patients. This study aimed to validate chest trauma scoring systems in polytrauma patients. Methods: Data from 1,038 polytrauma patients were analyzed. The primary outcomes were one or more complications: pneumonia, chest complications requiring surgery, and mortality. The Thoracic Trauma Severity Score (TTSS), Chest Trauma Score, Rib Fracture Score, and RibScore were compared using receiver operating characteristic (ROC) analysis in patients with or without head trauma. Results: In total, 1,038 patients were divided into two groups: those with complications (822 patients, 79.2%) and those with no complications (216 patients, 20.8%). Sex and body mass index did not significantly differ between the groups. However, age was higher in the complications group (64.1±17.5 years vs. 54.9±17.6 years, P<0.001). The proportion of head trauma patients was higher (58.3% vs. 24.6%, P<0.001) and the Glasgow Coma Scale score was worse (median [interquartile range], 12 [6.5-15] vs. 15 [14-15]; P<0.001) in the complications group. The number of rib fractures, the degree of rib fracture displacement, and the severity of pulmonary contusions were also higher in the complications group. In the area under the ROC curve analysis, the TTSS showed the highest predictive value for the entire group (0.731), head trauma group (0.715), and no head trauma group (0.730), while RibScore had the poorest performance (0.643, 0.622, and 0.622, respectively) Conclusions: Early injury severity detection and grading are crucial for patients with blunt chest trauma. The chest trauma scoring systems introduced to date, including the TTSS, are not acceptable for clinical use, especially in polytrauma patients with traumatic brain injury. Therefore, further revisions and analyses of chest trauma scoring systems are recommended.

Objective : The popular grading systems in use, such as Hunt-Hess grade and Fisher scale score, are based primarily on the patient's clinical conditions or computerized tomography score after aneurysmal subarachnoid hemorrhage(SAH). The author investigated whether the need for ventriculoperitoneal(VP) shunt for chronic hydrocephalus and outcome can be predicted by Hunt-Hess grade and Fisher scale. Methods : A series of 146 patients admitted to our hospital from August 1991 to July 1999, who presented with SAH and underwent craniotomy for aneurysm clipping were studied retrospectively. Chronic hydrocephalus was defined as clinically and radiographically demonstrated hydrocephalus that lasted 2 weeks or longer after initial hemorrhage which required shunting. Patients were evaluated based on following factors : Hunt-Hess grade, Fisher scale, age, sex, hypertension, aneurysm location, and intervals from aneurysm rupture to operation. Results : The overall mortality rate of the study group was 8.2%. Hunt-Hess grade(p=0.001) or Fisher scale (p=0.001) at all pretreatment times was significantly correlated with outcome. In addition, there was an increased risk of poor outcome in older age(65<). However, there were statistically no significant relationship between outcome and sex, location of aneurysm, hypertension, and interval from aneurysmal rupture to operation(p>0.05). Of 134 surviving patients, 16 patients(12%) underwent VP shunt placement secondary to chronic hydrocephalus. Hunt-Hess grade(p=0.001) is more predictive of chronic hydrocephalus than Fisher scale(p=0.146). Aneurysm location was significantly correlated with development of chronic hydrocephalus (p<0.05), without significant correlations in sex, age, hypertension. IVH, and ICH. Conclusion : This study suggests that there is a high clinical correlation between outcome and Hunt-Hess grades and Fisher scales on admission, but Hunt-Hess grade is more predictive for chronic hydrocephalus than Fisher scale. In addition, age(<65 yrs) is the significant factor for prediction of outcome. There was a trend of increasing risk for chronic hydrocephalus according to aneurymal location.

Objective: The authors reviewed clinical and radiological outcomes in patients with three column injury of the cervical spine who had undergone posterior cervical fixation using Nitinol shape memory alloy loop in the anterior-posterior combined approach. Materials: Nine patients were surgically treated with anterior cervical fusion using an iliac bone graft and dynamic plate-screw system, and the posterior cervical fixation using Nitinol shape memory loop ($Davydov^{TM}$) at the same time. A retrospective review was performed. Clinical outcomes were assessed using the Frankel grading method. We reviewed the radiological parameters such as bony fusion rate, height of iliac bone graft strut, graft subsidence, cervical lordotic angle, and instrument related complication. Results: Single-level fusion was performed in five patients, and two-level fusion in four. Solid bone fusion was presented in all cases after surgery. The mean height of graft strut was significantly decreased from $20.46{\pm}9.97mm$ at immediate postoperative state to $18.87{\pm}8.60mm$ at the final follow-up period (p<0.05). The mean cervical lordotic angle decreased from $13.83{\pm}11.84^{\circ}$ to $11.37{\pm}6.03^{\circ}$ at the immediate postoperative state but then, increased to $24.39{\pm}9.83^{\circ}$ at the final follow-up period (p<0.05). There were no instrument related complications. Conclusion: We suggest that the posterior cervical fixation using Nitinol shape memory alloy loop may be a simple and useful method, and be one of treatment options in anterior-posterior combined approach for the patients with the three column injury of the cervical spine.

Background and Objetive : The aim of this study is to report 3 cases of facial palsy following microvascular decompression in hemifacial spasm patients. It is a rare disease, with few research on the effect of acupuncture therapy on it. Material and Method : We selected 3 cases of facial palsy following microvascular decompression in hemifacial spasm patients, among patients who visited the Facial palsy Clinic of Kyunghee Oriental Medical Center. We treated them with acupuncture therapy(ST6, ST4, BL2, TE17, GV24, GV14, and Ex-HN4 of the healthy side, and LI4 and ST36 of both sides) and aroma therapy. After treatment we observed and checked any changes within clinical symptoms using the House-Brackmann Grade and the Yanagihara's Unweighted Grading System. Result and Conclusion : 1. All three cases were of hemifacial spasm patients who had facial palsy following microvascular decompression. The patients visited 27 months(Case1), 2 months(Case2) and 7 months(Case 3) after the surgery respectively. 2. Period of time till complete recovery is 23 months(Case1), 8 months(Case2) and 3 month (Case3) respectively. 3. All three cases had symptoms of sequelae: retraction of mouth toward the healthy side and involuntary spasm of lips. The later the initiation of treatment after the sugery, the more severe symptoms of sequelae.

Purpose: Pyrethroid is an insecticide that produces moderate intoxication in mammals, with neither exposure to skin nor inhalation resulting in severe systemic manifestations. In 2005 we made a nationwide survey of agrichemical human intoxication. The object of this study is to analyze pyrethroid intoxications based on the 2005 survey. Methods: We prospectively collected data from 1 August 2005 to 31 July 2006 by a standard investigation protocol. We analyzed demographic data, exposure data (cause, amount, ingredients), clinical features, and courses. Results: A total of 125 cases of pyrethroid intoxication were surveyed. The mean patient age was $56.78{\pm}16.158$ years old, and the mean amount ingested was $121.85{\pm}110.732ml$. Patients were classified into four severity groups according to symptoms and mental status: the asymptomatic group (27 patients, 21.6%), the mild symptom group (48, 38.4%), the moderate symptom group (21, 16.8%), and the severe symptom group (7, 5.6%). There were statistically significant differences in mental status, severity, and mean ICU days between two groups. Admission days by severity grade for the asymptomatic, mild, moderate, and severe symptom groups were $5.49{\pm}16.051,\;3.65{\pm}4.143,\;4.59{\pm}3.335,\;and\;8.14{\pm}7.199days$, respectively (p=0.047). Conclusion: Nationwide surveillance was extremely telling in uncovering a high frequency of agrichemical intoxication in Korea. In pyrethroid intoxication, severity grading can be a useful prognostic tool.

Objective : This study aims to determine the optimal dose of recombinant-human bone morphogenic protein-2 (rhBMP-2) for successful bone fusion in minimally invasive lateral lumbar interbody fusion (MIS LLIF). Previous studies show that rhBMP is an effective alternative to autologous iliac crest bone graft, but the optimal dose remains uncertain. The study analyzes the fusion rates associated with different rhBMP doses to provide a recommendation for the optimal dose in MIS LLIF. Methods : Ninety-three patients underwent MIS LLIF using demineralized bone matrix (DBM) or a mixture of rhBMP-2 and DBM as fusion material. The group was divided into the following three groups according to the rhBMP-2 usage : group A, only DBM was used (n=27); group B, 1 mg of rhBMP-2 per 5 mL of DBM paste (n=41); and group C, 2 mg of rhBMP-2 per 5 mL of DBM paste (n=25). Demographic data, clinical outcomes, postoperative complication and fusion were assessed. Results : At 12 months post-surgery, the overall fusion rate was 92.3% according to Bridwell fusion grading system. Groups B and C, who received rhBMP-2, had significantly higher fusion rates than group A, who received only DBM. However, there was no significant increase in fusion rate when the rhBMP-2 dosage was increased from group B to group C. The groups B and C showed significant improvement in back pain and Oswestry disability index compared to the group A. The incidence of screw loosening was decreased in groups B and C, but there was no significant difference in the occurrence of other complications. Conclusion : Usage of rhBMP-2 in LLIF surgery leads to early and increased final fusion rates, which can result in faster pain relief and return to daily activities for patients. The benefits of using rhBMP-2 were not significantly different between the groups that received 1 mg/5 mL and 2 mg/5 mL of rhBMP-2. Therefore, it is recommended to use 1 mg of rhBMP-2 with 5 mL of DBM, taking both economic and clinical aspects into consideration.
