Early loss of primary teeth among children in Thamar city, Yemen
Objectives: The premature loss of primary teeth is a potential risk factor for poor arch length development. Adequate arch length is important to the progression of the permanent teeth. Poor arch length can lead to crowding, ectopic eruption, or impaction of these teeth. This study is designed to assess the prevalence of premature loss of primary teeth in the 5-10-year-old age group. Materials and Methods: The study group included 185 children, that is, 91 boys and 94 girls. The dental examination was conducted by an experienced examiner under sufficient artificial light. Data including patient age and missing teeth were collected. Descriptive statistics were applied for data analysis, and from the results, Chi-square tests were used at a level of significance of 5% (P < 0.05). Results: We observed a 40.54% prevalence of premature loss of primary teeth with no statistically significant difference between genders. The lower left primary second molar was the most commonly absent tooth in the dental arch (13.5%). Conclusion: The status of premature loss of primary teeth was high in the study group. Implementation of efficient educational and preventive programs to promote oral health would help children maintain a healthy primary dentition and eventually prevent the disturbances in the future development of normal occlusion. Early detection and management of the space problems associated with the early loss of primary teeth would help in reducing malocclusion problems
RADIOGRAPHIC ASSESSMENT OF THE COURSE AND VISIBILITY OF THE MANDIBULAR CANAL BY PANORAMIC RADIOGRAPHY
Background and Objectives: The mandibular canal is a canal inside the mandible that contains the inferior alveolar artery, the inferior alveolar nerve and the inferior alveolar vein. The anatomy and variations of the human mandible are very important for planning various surgical measures such as extraction of the third molar, dental implants and mandibular reconstruction. This study was conducted to determine the frequency of the different courses of the mandibular canal and to investigate the visibility of the mandibular canal by panoramic radiography, among a sample of Yemeni adults.
Subjects and Methods: A retrospective cross-sectional study was conducted in Sana'a city on a sample of Yemeni adults. The study consisted of panoramic radiographs of 928 patients; the number of males was 340 (36.6%) and 588 females (63.4%). The mandibular canal course, as shown in the panoramic radiographs, was classified into four types: elliptical, linear, turning curves and spoon-shaped. The visibility of this canal from the first to the third molar region was assessed through visual determination of whether the lower canal was clearly visible, possibly visible, or invisible.
Results: Elliptical curves were the most observed along the mandibular canal course at 62.2% of the total, followed by the linear curve (24.8%) while the lower rate curve spoon (7.9%) and the turning curve (5.2%). There were no statistically considerable differences between the distribution of the mandibular canal courses between males and females except in the spoon curve where the ratio was 10.8% in males versus 6.1% in females (p <0.05). The percentage of clearly visible mandibular canals was the highest among the spoon-shaped curves (49.9% in the first molar, 63% in the second, 78.1% in the third molar) and the lowest among the linear curves (10.9% in the first, 18.7% in the second and 33.5% in the third molar). On panoramic radiographs, the invisible mandibular canals are found in 198 (21.3%) of the examined sites in the first molar region, in 85 (11%) in the second molar region, and in only 6 (0.64%) in the third molar region.
Conclusion: It was observed that elliptical curves along the path of the mandibular canal were the most present, while a decrease in the ratio of the two types of spoon curve and turning curve was observed. It was found that spoon curve was significantly more common among males than females. It was also found that the visibility of madibular canal is fewer in the first molar region than in the third molar region.

PREVALENCE AND CAUSES OF TRAUMATIC DENTAL INJURIES TO ANTERIOR TEETH AMONG PRIMARY SCHOOL CHILDREN IN SANA'A CITY, YEMEN
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.

SERO-PREVALENCE OF HEPATITIS C VIRUS AMONG DENTAL CLINIC WORKERS IN SANA’A CITY- YEMEN AND THE RISK FACTORS CONTRIBUTING FOR ITS INFECTIO
PREVALENCE OF MALOCCLUSION AMONG YEMENI CHILDREN OF PRIMARY SCHOOLS
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.

OCCLUSAL CHARACTERISTICS OF THE PRIMARY DENTITION AMONG A SAMPLE OF YEMENI PRE-SCHOOL CHILDREN
Objective: The occlusal features change dynamically in the growing children and any disruption in the complex craniofacial growth process may lead to malocclusion, which is a major concern for the pediatric community because of its effects on dental function and beauty, as well as on the child's psyche. The aim of the present study was to study the prevalence of different occlusal traits in the primary dentition of the randomly selected pre-school children from three to five years in the city of Sana’a, Yemen.
Methods: The study includes 1106 pre-school children subjected to a dental examination performed in the school premise, using the Foster and Hamilton criteria for occlusal traits. As well as inter- and intra-calibration tests were conducted for assessing the degree of agreeability.
Results: Results of the study showed that the Bilateral flush terminal molar relationship was found in 60%, bilateral mesial step in 27.9%, asymmetrical relationship in 8.5% and distal step in 3.5% of tested children. The Bilateral canine class I was detected in 62.8%, asymmetrical relationship (13.6%), class II (12.5%) and class III (11.1%). Normal over-jet (OJ) of 1-3 mm was identified in 39.2%, decreased OJ <1 mm (32.7%) and edge-to-edge (8.8%). Ideal over-bite (OB) of 1-50% was detected in 64.5% and increased OB of > 50% (19.7%).
Conclusion: In conclusion theBilateral flush terminal molar, class I canine relationships, normal overjet (OJ) of 1-3mm were the most commonly found sagittal occlusal traits in the current study. Ideal over-bite (OB) of 1-50% were identified in more than half of the children.

KNOWLEDGE AND PERCEPTION OF MOLAR INCISOR HYPOMINERALIZATION AMONG DENTAL PRACTITIONERS IN SANA’A CITY- YEMEN
Background: Molar incisor hypomineralization (MIH) has been recognized as a global dental disorder and concern about this pathology is growing among clinicians around the world.
Objectives: This study aimed to investigate the knowledge and perception of Yemeni dental practitioners in the city of Sana'a in relation to diagnosis, etiological factors and management of MIH.
Materials and Methods: A questionnaire modified from similar previous studies was distributed to 311 Yemeni dentists providing oral health care in Sana'a city. The survey consists of two parts, the first is the demographic-occupational variables that was collected for the participants and the second part included questions related to perception of the diagnosis, possible etiological factors, severity of the condition and management, and the participants ’willingness for advance training in relation to MIH.
Results: The overall response rate is (90%). The majority of respondents came across MIH in their practices (GDPs= 83.2%, SDPs= 90%).Yellow / brown demarcation is feasible as a common clinical symptom. The composite resin was the most used restorative material. The genetic factor was the most specific etiological factor. Most GDPs were significantly uncertain in the diagnosis of MIH compared to SDPs (P = 0.003). Most of the respondents (72.5%) had a low level of knowledge regarding MIH. Participants support the need to assess MIH occurrence and conduct clinical training.
Conclusion: Molar incisor hypomineralization (MIH) is a common dental problem faced by dental practitioners in Sana'a City who have required clinical training regarding diagnosis, etiological factors and MIH management. Â

BIOFILM FORMATION AND ANTIFUNGAL SUSCEPTIBILITY OF CANDIDA ISOLATES FROM ORAL CAVITY AFTER THE INTRODUCTION OF FIXED ORTHODONTIC APPLIANCES
Background and aims: Fixed Orthodontic Appliances (FOA) act as diverse impact zones and modify microbial adherence and colonization, acting as unfamiliar reserves and potential sources of infection This study was conducted to inspect the effect of the introduction of fixed orthodontic appliances on the growth and adherence (biofilm formation) of Candida species. And also to reveal the species distribution and antifungal sensitivity to isolated Candida species.
Material and methods: The trial group was chosen from orthodontic patients whom were inspected clinically as soon as to get baseline information prior to active treatment. The group included 210 patients; 165 females, and 45 males, (mean age 21.6 ± 4.5 years). Clinical, demographic, and risk factor data were collected in a standard questionnaire and then each individual was directed to perform an oral rinse with phosphate-buffered saline, which was expectorated and processed proposed for the isolation and identification of Candida species by standard methods. After that, the isolated Candida species were tested for biofilm production by the phenotypic method i.e. Tissue culture palate methods (TCPM). Finally, antibiogram susceptibility pattern of oral Candida species was done by Kirby-Bauer disc diffusion method for amphotericin B, ketoconazole, and fluconazole.
Results: The most common yeast colonized oral cavity after the introduction of FOA was C. albicans (72.5%), followed by C. glabrata and C. tropicalis (12.5%), while Candida parapsilosis only was 2.5%. The rate of formation of biofilms was 52.5% for all types of Candida, and it was found that biofilm formation occurs more frequently among C. tropicals and C. glabrata (60%) than C. albicans (48.3%). All Candida species isolates were sensitive to amphotericin B and ketoconazole while resistance to fluconazole was found in 40% of C. tropicalis and 20% in C. glabrata and 13.8% in C. albicans.
Conclusion: The present study proved that C. albicans is still the major isolate from the oral cavity after the introduction of FOA, but non-albicans species colonization is raised and FOA might be a factor for biofilm formation. The C. tropicalis and C. glabrata were more– biofilm-producers compared to C. albicans. The isolated species in the current study are less susceptible to fluconazole and drug resistant factor in the Candida species isolates was found to be associated with biofilm formation.

ORAL CANDIDA ALBICANS COLONIZATION RATE IN FIXED ORTHODONTICS PATIENTS
Objectives: The objective of this study was to assess the oral Candida albicans colonization ( OCAC) in a cluster of teenagers and young adults while being treated with a fixed orthodontic appliance (FOA).
Subjects and methods: The investigational group was selected from orthodontic patients whom were examined clinically as soon as to get baseline information before active treatment. The cluster included 210 patients; 45 males, 165 females (mean age 21.6 ± 4.5 years). Clinical, demographic data and risk factors were collected in standard questionnaire then each individual was directed to carry out oral wash by a phosphate-buffered saline solution, which was expectorated and processed intended for the isolation of Candida species on Sabouraud’s dextrose agar. The isolated Candida species were identifying by culturing on chromogenic Candida agar and notice species-specific colony natures.
Results: The predominant Candida species isolated was C. albicans with OCAC rate equal to 13.8% extensively enhanced after the insertion of a FOA, as revealed by the oral rinse (P < 0.05) techniques. The results also revealed an increase of OCAC in male patients (24.4%) than female patients (10.9%), 21-25 years patients (17.1%), and regular smoking and Qat chewing were significant associated risk factors (OR=28.6, OR=10.7 respectively , P < 0.0001). There was no significant association between C. albicans colonization with oral hygiene in fixed Orthodontic patients.
Conclusion: As a whole, the current data suggest that the introduction of FOA is likely to promote OCAC. Moreover, it becomes visible that the routine oral hygiene procedures performed by these patients may not necessarily reduce OCAC while smoking and chewing Qat habits significantly increased OCAC in FOA. Also smoking and Qat chewing during FOA treatment should be banned if potential harmful effects are to be prevented. Further work with a larger sample size is required to confirm or deny these results.

PREVALENCE OF STAPHYLOCOCCUS AUREUS IN DENTAL INFECTIONS AND THE OCCURRENCE OF MRSA IN ISOLATES
Objectives: Staphylococcus aureus is an opportunist that causes systemic infections and dental infections in the human being body. This organism increases its resistance to many categories of antibiotics all day and turn out to be more resistant, and this led to a growing feeling of concern in this era. Given this fact, the aims of this study were to determine the frequency of S. aureus in oral infections and to determine the prevalence of MRSA strains and the sensitivity of isolated S. aureus to antibiotics, in patients who attended dental clinics in major public hospitals and private clinics in the city of Sana'a-Yemen.
Subjects and methods: The study was conducted for a year, early in December 2018 and ending in November 2019. The study included 296 patients, 153 male and 143 female, ages 5 to 65, with an average age of 36.2 years. Demographic and clinical data were collected in questionnaire, then pus or oral swabs were collected from patients, cultivated, isolated and identified by standard laboratory techniques. MRSA was ascertained by means of the method of disc diffusion to 1µg of oxicillin disc and 5 µg of methacillin disc; an antimicrobial sensitivity test was carried out by disc diffusion method of selected antibiotics.The oral infections include dental abscesses, periodontal abscesses, gingivitis, periodentitis, dental caries, pulpitis and oral thrush.
Results: Of a total of 296 cultured pus and swabs, only 217 produced a positive culture (73.3%). Gram-positive bacteria formed 67.4% of the total isolates where S. aureus was the predominant pathogen (43.1%). The prevalence of MRSA was 23.5%. There was a higher rate of antibiotic resistance tested in MRSA isolates compared to a lower rate of resistance in MSSA as well as 22.2% of MRSA isolates were vancomycin resistant, while only 11.4% of MSSA were vancomycin resistant.
Conclusion: It can be concluded, S. aureus was the most widespread isolate in dental infections, high rate of MRSA, the appearance of S. aureus isolates resistant to vancomycin and other broad choice of antibiotics have raised MRSA in oral infections into a multi-drug-resistant, making it more and more hazardous in oral infections. Consistent assessment of oral associated infections and observing the pattern of antibiotic sensitivity and strict drug policy for antibiotics are recommended.

PREVALENCE OF PREMATURE LOSS OF PRIMARY TEETH AT THE AGE OF 6-10 YEARS IN SANA'A CITY, YEMEN
Background and Objectives: Primary teeth and the integrity of the primary teeth are very important for the normal growth and progress of the occlusal relationships and the dentofacial structures. Premature loss of the primary teeth may lead to the loss of the arch length needed for the eruption of permanent teeth and thus lead to rotation, crowding, and impaction of permanent teeth. This study aimed to determine the prevalence of premature loss of primary teeth among children aged 6-10 years in Sana'a city, Yemen.
Materials and methods: This observational cross-sectional study included 1091 children, aged 6-10 years. An experienced examiner the first author carried out all clinical examinations under natural light. Data were collected including age and missing teeth.
Results: The results showed that 26% of the sample suffered premature loss of primary teeth with no significant difference between the sexes (P> 0.05). There was low in prevalence of premature loss of primary teeth in 10 years (17.7%), while the rate raised to 29.7%, 31.6%, and 31.7% in 6,7 and 9 years respectively. When considering the number of teeth, the prevalence of one premature loss was 10.8%, followed by two premature losses (9.8%), while the loss rate of 3 or more was5.4%. Considering dental arch 61.8% of loss was Mandible loss, while the loss in Maxilla was 38.1% only. The most common missing tooth is the first lower right primary molar (17%).
Conclusion: The prevalence of premature loss in our study is similar to that of developing countries, the rate was low at 10 years for children, while the rate increased at 6,7 and 9 years; most of the loss was in the lower jaw and the most common missing tooth was the right lower primary molar. This result determines the importance of increasing awareness of this problem and focusing on the need for more preventive efforts to maintain healthy and natural teeth that improve the chewing function and aesthetic appearance of children and the entire population.

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.
