Introduction and objective: Mixed dentition space analysis methods via Tanaka-Johnston analysis are regularly used all over the world. Conversely, the appropriate of this analysis between different ethnic groups is dubious. The study aimed to test the appropriate of the Tanaka-Johnston analysis for Yemeni adults and to arise regression equations designed for Yemen population if needed.  Methods: The study included two hundred and twenty-seven (106 males and 121 females) Yemenis from Sana'a University, University of Science and Technology, and Al-Rehab Private Clinic. The mesiodistal widths of the four permanent lower canines, incisors, and premolars for the entire quadrants were determined with a digital caliper to the nearest 0.01 mm. To compare average presentation values ​​derived from this study with values ​​derived using Tanaka-Johnston equations, Student's paired t-test was used, as well as the chi-square (χ2) test used for appropriateness of fit. Result: Gender differences were observed in the total mesiodistal width of both canines and premolars in both arches as revealed by the t-test (p < 0.001). The sum of the actual mesiodistal width of the canines and premolars was compared with the expected widths derived from the Tanaka and Johnston equation and significant differences (p<0.001) were found. Regression analysis indicated that the sum of the mesiodistal width of the permanent mandibular incisors is a good predictor of that of un-erupted canines and premolars, with correlation coefficients ranging from 0.51 to 0.61. Accordingly, two linear regression equations were developed to predict tooth width for Yemeni males and females. Conclusion: It was concluded from this study that the Tanaka-Johnston analysis did not accurately predict the mesiodistal width of the unruptured canines and premolars of the Yemeni population. Moreover, new regression equations have been developed for the research sample that can be a standard for Yemen. However, further studies must be performed to verify the applicability and accuracy of these equations.                   Peer Review History: Received: 10 November 2021; Revised: 12 December; Accepted: 29 December, Available online: 15 January 2022 Academic Editor: Dr. Asia Selman Abdullah, Pharmacy institute, University of Basrah, Iraq, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Objectives: The current study was conducted to reveal the prevalence and causes of traumatic dental injuries to permanent anterior teeth among mixed dentition of schoolchildren in Sana'a City, Yemen. Methods: A cross-sectional study was performed on 1252 schoolchildren aged 7-12 years in three districts of Sana'a city, Yemen. They numbered 700 males and 552 females from 26 randomly selected public and private schools. Clinical examination of permanent anterior teeth was done according to the classification of Ellis modified by Fried. Results: Prevalence of TDI was 10.30%, with a male ratio of 4.8: female 1, (P <0.05). Most of the children suffered only one damage to the tooth and most of them are in the maxillary central incisors. The TDI increased with older age (10-12 years old) (16.5%) with odds ratio 4.8, (p<0.05). Regarding the site of trauma, most injuries happened in males on the street (44.9%) while in females happened at home (31.81%) and falls were the main cause of TDI. In both sexes, the most common type of injury was class I (enamel fracture) followed by class II (enamel and dentine without pulp involvement). Conclusion: In conclusion, the prevalence of TDI in permanent anterior teeth among mixed dentition of school children in Sana’a was high, higher in males than in females, with a peak age of 10 to 12 years, falls was the common cause, and occurred mostly on the street for boys and home for females. Accordingly, educational programs should be developed that focus on ways to prevent dental trauma and the benefits of seeking urgent treatment to maintain avulsed and fractured teeth.

Introduction: Preeclampsia is a cause of high morbidity and mortality in pregnant women. Serum albumin is found to be low in preeclampsia. Few recent studies have shown a state of hypothyroidism in preeclampsia. Aim: To find the association between the serum albumin and thyroid hormone levels in preeclampsia and seek to find if hypoalbuminemia increases the risk of hypothyroidism. Materials and Methods: A case-control study was done at Department of Biochemistry and the Department of Obstetrics and Gynaecology of Government Medical College, Thiruvananthapuram, Kerala, with 40 preeclampsia cases and 40 normal pregnant controls, in 30-38 week gestation. Serum albumin and thyroid profile-Total T3, Total T4, Thyroid Stimulating Hormone (TSH), freeT3 (fT3), freeT4 (fT4) were tested. Statistical analysis was done with Student’s t-test, Chi-square, Fischer’s t-test and Pearson’s correlation coefficients. Results: The mean serum albumin was significantly lesser in preeclampsia (3.11±0.39) than in controls (3.7±0.14 g/dL). Thyroid hormones were significantly decreased in preeclampsia. TSH was significantly raised (3.76±1.55 mIU/L) in preeclampsia compared to normal pregnant ladies (2.3±0.94 mIU/L). In cases with hypoalbuminemia, risk for hypothyroidism was 2.85 times compared to those with normal albumin but was not statistically significant. In severe preeclampsia, there was a two times increased risk. There was a negative correlation of TSH and positive correlation for fT4 with serum albumin. However, this was statistically not significant. Conclusion: Hypothyroidism in preeclampsia was not significantly correlated with hypoalbuminemia in this study. Thus hypoalbuminemia did not significantly increase the risk for hypothyroidism in our study. Further studies are needed to determine the risk factors affecting thyroid function in preeclampsia.

Objective: Malocclusion is every difference in the arrangement of teeth beyond the standard of regular occlusion illustrated by anomalies within the dental arches. The purpose of this study was to measure prevalence of malocclusion between primary school children in Sana’a city Yemen. Methods: A cross sectional study was conducted on 1079 school children (546 girls and 533 boys), their age ranged from 7 to 12 years old from public and private schools selected randomly in Sana'a City, Yemen. The prevalence of malocclusion was investigated according to age, gender and school type based on Angle's classification. Results: The study showed that the overall prevalence of malocclusion among school children was 81.1%, in which Class I normal molar association was found only in 18.9% of school children, while Class I malocclusion included the highest percentage of the sample 70.4%, followed by Class II relation 9.5%, and Class III involved only 1.1%. The most prevalent malocclusion trait was spacing 35.7%, whereas the crowding was present in 30.0% of the sample. The deep bite was present in 10.1% followed by anterior crossbite 8.8%, midline diastema 8.6%, anterior open bite 4.5%, posterior crossbite 4.0%, and the least noted malocclusion trait was posterior open bite 0.4%. Conclusion: In conclusion, there was a high rate of malocclusion in school children and significantly increased with age, class I malocclusion was the most common followed by Class II malocclusion, while Class III was the rear. The most prevalent occlusal problem was spacing, followed by crowding.  Thus, 7-12 year-olds can benefit from interceptive and preventive oral health procedures which may either entirely prevent or reduce the development of serious types of malocclusions afterward in their lives.

Abstract Aims Prediction of the mesiodistal crown width of unerupted canines and premolars is an important aspect of mixed dentition analysis. The accuracy of Tanaka-Johnston equations, the most commonly method, is questionable when it is applied to different ethnic groups. In this study, we aimed to develop a new regression equation for this prediction in an Iranian population. Materials and methods The dental casts of 120 Iranian subjects with complete permanent dentition were selected. Mesiodistal crown widths of teeth were measured with digital caliper. In the first part of the study, the correlation and linear regression equations between four mandibular incisors and the canine-premolars segments of both arches were developed (modified Tanaka-Johnston equation). In the second part, as a new method, correlation and linear regression equations were developed between the sum of mandibular central incisorsmaxillary first molars and the canine-premolars segments. Results It was found that the correlation coefficients between the sum of mandibular central incisors-maxillary first molars and the maxillary and mandibular canine-premolars segments were higher (r = 0.66, 0.68 respectively) than the one between the four mandibular incisors and the canine-premolars segments (r = 0.58. 0.64). Conclusion New linear regression equations were derived. In this study, the sum of mandibular central incisors and maxillary first molars was better predictor for unerupted canines and premolars. This novel approach allows the prediction of width of unerupted canines and premolars to take place at earlier age. Clinical significance Using the new method, orthodontists could take advantage of mixed dentition analysis at earlier age. Moreover, to test the derived equations on a larger sample size and in other ethnicities is highly recommended. How to cite this article Toodehzaeim MH, Aghili H, Shariatifar E, Dehghani M.

Odontogenic Origin

Background: Odontogenic infections vary from minor abscesses to superficial and deep infections that lead to acute infections in the head and neck area that may threaten the patient's life.  The objectives of this study are to identify bacteria accountable for orofacial infection of odontogenic origin and patterns of their susceptibility to drugs in order to provide a superior understanding of dental infection management in Yemen. Methods:  The study was conducted on a selected group of patients, regardless of gender and age, who suffer from severe to moderate orofacial infections of odontogenic origin and were admitted to the dental clinic at the Republican University Hospital in Sana'a city. Sample of pus was collected and the bacteria were identified by cultivation in suitable medium and then identified by standard bacteriological techniques. Antimicrobial susceptibility testing was also performed using the Kirby-Bauer disc diffusion method. Result:  A total of 118 cases were positive for bacterial culture, 63 males and 55 females ranged between 5 and 65 years of age, most of them in the age group> 45 years (39.8%), 51.7% had dental abscesses and 48.3% had periodental abscesses. Staphylococcus aureus, Bacteroides species and Staphylococcus epidermidis were isolated from patients with dental abscesses, Staphylococcus aureus, Bacteroides species, Staphylococcus epidermidis and Streptococcus pyogens  from perio-Dental abscesses. The most prevalent bacteria were Staphylococcus aureus (about 63% of the total isolates), more than 40% of which were resistant to ceftizoxime, calithromycin, augmentin, tetracyclines, erythromycin and oxacillin. While Staphylococcus  epidermidis showed less antibiotic resistance than Staphylococcus aureus. As for the Bacteroids species, it was sensitive to metronidazole and clindamycin (100%), augmentin (98.6%), calrithromycin (94.4%) and finally vancomycin (76.1%).  Conclusion: An elevated occurrence of bacterial isolates was discovered, and Staphylococcus aureus was dominant.Most of the isolated bacteria were resistant to diverse classes of antibiotics. Appropriate antibiotics should be administered based on the bacterial isolates, culture sensitivity, and clinical course of disease.                         Peer Review History: Received 6 November 2020; Revised 22 Decembe; Accepted 5 January, Available online 15 January 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Abstract Aim The aim of this pilot study was to evaluate equations for predicting the size of unerupted canines and premolars during the mixed dentition period in an Iranian population. Methods and Materials This cross-sectional analysis was performed on 106 subjects (52 girls, 54 boys, aged 13–15 years). Data were obtained from dental cast by making direct measurements of the maximum mesiodistal widths of all mandibular and maxillary incisors, canines, premolars, and first molars with an electronic digital sliding caliper, with an accuracy of ±0.02 mm and repeatability of ±0.01 mm. The results were statistically analyzed using Student t tests, Pearson product-moment coefficients, and ANOVA tests. Correlation coefficients (r) and error variance of estimates were determined using a significance level of p<0.05. Results No significant differences were found between the mesiodistal tooth widths of males and females in this Iranian population. The highest correlation was between the sum of the mesiodistal width of canines and premolars in the maxilla with the mesiodistal width of the mandibular first molars and maxillary central incisors (r=0.742). A moderate correlation was obtained in the mandible (r=0.665). Approximations were developed to predict the size of the unerupted canines and premolars in both jaws (in the maxilla, Y = 0.740X + 14.271, or the simplified formula, Y = 3/4X + 14; for the mandibular arch, Y = 0.658X + 16.353, or the simplified formula, Y = 2/3 X + 16). Conclusion The strongest correlation was found for the sum of the mesiodistal width of canines and premolars in the maxilla with the mesiodistal width of the mandibular first molars and maxillary central incisors in the maxillary analysis (r=0.742). A moderate correlation was found in the mandible for the sum of the mesiodistal width of canines and premolars with the mesiodistal width of the mandibular first molars and maxillary central incisors (r=0.665). Clinical Significance The simplified equations proposed for the maxillary arch (Y = 3/4 X + 14) and for the mandibular arch (Y = 2/3 X + 16) offer an easy and practical way to predict the size of unerupted canines and premolars in the maxillary and mandibular arches of Iranian children.

The purpose of this study was to examine the association between perceived and actual movement skill competence among primary school children in Hong Kong. Participants were 568 primary (P) school children (229 boys, 339 girls; Mage = 9.3 years, SD = 1.7). Children’s perceived skill competence was assessed using an identical format to that of Harter’s Self-Perception Profile for Children in the same 12 fundamental movement skills (FMS) objectively measured. The actual locomotor and object control skills were assessed using the Test of Gross Motor Development (2nd edition). Pearson’s correlation coefficients were calculated to examine the association between children’s perceived and actual movement skill competence separately for lower (P1–P3) and upper (P4–P6) grades. There was no association between students’ perceptions and actual FMS scores. MANCOVA results indicated that children in upper grades had significantly lower skill perceptions than their younger counterparts. Overall, boys had higher perceptions of object control skill than girls did. The findings indicate that many primary school children have inaccurate perceptions of their FMS competence. These misperceptions may lead to low self-confidence and to gradually opting out of sport and physical activity.

Background:  Trachoma is a contagious infection caused by Chlamydia trachomatis. The disease causes roughness of the inner surface of the eyelids which in turn leads to eye pain, collapse of the outer surface and scratching of the cornea, and ultimately blindness. Objectives: This study was designed to determine Trachoma prevalence and associated risk factors among primary school children in Sana’a city, Yemen. Methods: A cross-sectional study was performed on 991 schoolchildren aged 6-12 years that were chosen from sixteen primary public schools and ten private ones, that are located in five districts in Sana’a city and represent nearly 10% of total number of schools in Sana’a. Child's eye examination was done by trained 12 students of Medicine, according to WHO grading system for trachoma. Data on risk factors and health characteristics of a child were collected using a structured questionnaire and statistical analysis was performed using Epi-Inf version 6. Results:  The gender distribution of study contributors was male 41.7 % and female was 58.3%. The results of independent associated odds ratio analysis discovered that risk factors of contracting Trachoma from the upper to the lower are: Absent of latrine in the house of child  (OR=10.6,  p<0.001), orphan of mother  (OR=4.7,  p<0.001), absent of water in the house of child (OR=3.9, p<0.001), flies in the face (OR=1.9, p=0.005) , No education of the mother (OR=1.7,  p=0.01), No education of the father (OR=1.6, p=0.04), No  face washing with  soap per day (OR=3.1, p=0.001), keeping animals in living house (OR=1.6, p=0.03), and house overcrowding (OR=2.5, p=0.002). Conclusion: Area was identifiedidentify where, at the time of the survey among 10-12 children, as defined by WHO trachoma was a public health problem. As for the loss of the child to his parents, especially the loss of the mother, it is a disaster for the child, so the treatment of causes such as war and poverty for this problem should be a priority in Yemen                    Peer Review History: Received: 15 July 2021; Revised: 9 August; Accepted: 6 September; Available online: 15 September 2021 Academic Editor:  Dr. Sally A. El-Zahaby, Pharos University in Alexandria, Egypt, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.  Received file:                Reviewer's Comments: Average Peer review marks at initial stage: 6.0/10 Average Peer review marks at publication stage: 7.5/10 Reviewers: Dr. Rawaa Souhil Al-Kayali, Aleppo University, Syria, [email protected] Dr. Bilge Ahsen KARA, Ankara Gazi Mustafa Kemal Hospital, Turkey, [email protected] Dr. Wadhah Hassan Ali Edrees, Hajja University, Yemen, [email protected] Similar Articles: BACTERIAL CAUSES AND ANTIMICROBIAL SENSITIVITY PATTERN OF EXTERNAL OCULAR INFECTIONS IN SELECTED OPHTHALMOLOGY CLINICS IN SANA’A CITY  PREVALENCE OF MALOCCLUSION AMONG YEMENI CHILDREN OF PRIMARY SCHOOLS
