Molar Incisor Hypomineralization

Background: Periodontitis is an inflammation caused by plaque in the surrounding dental structures. It is a major factor in adult tooth loss. There is lack of information on associated clinical features, risk factors and microbial etiology of periodontitis in Sana’a, Yemen. Aim: The study focused on associated clinical features, risk factors and the separation and classification of bacteria in periodontitis and associated risk factors amongst patients attending dental clinics is Sana’a city.  Methods: First, 296 patients were admitted to the dental clinic at the Republican University Hospital and private dental clinics in Sana'a during a period of nearly one year, which began in December 2019 AD and ended in November 2020 AD, when they were diagnosed with dental diseases, then 49 of them were selected who are suffering from periodontitis, of whom 22 are males and 27 are females. Sterile paper points were used for the sample collection. Standard culture and biochemical techniques were used for the isolation and identification. Structured questionnaires were used to record clinical features, demographic variables and other risk factors of periodontitis. Results: A total of 130 microorganisms were isolated from 49 patients with periodontitis. Male patients accounted for 14.4% and females 18.9% of the all 296 patients who attended our clinics.  There was no important association between sex and periodontitis occurrence while there was significant association the younger age groups (45.4% in <26 years of age). The most common signs and symptoms were swollen or puffy gums (91.9%), bleed easily gums (96%), halitosis (96%), painful chewing (87.8%), pus between teeth and gums (71.4%), loose teeth or loss of teeth (44.9%), gingival recession (83.7%), spitting out blood when brushing or flossing teeth (79.6%), and tender gums (93.9%). Conclusion: This study is new in Sana'a city. The clinical features of preiodentitis in Yemen and the risk factors are similar to those reported in the literature elsewhere, but the isolated bacteria differ in frequency from those reported elsewhere, as some upper respiratory tract pathogens such as Streptococcus pyogenes are commonly isolated in this study. Knowledge of the clinical features, bacterial causes of gum disease, and risk factors is the key to successful periodontal therapy.                     Peer Review History: Received 8 January 2021; Revised 5 February; Accepted 25 February, Available online 15 March 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

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.

 Currently the world is facing a pandemic disease, namely Coronavirus disease 2019 (COVID-19) that is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). As finding recent drugs targeting COVID-19 will take a long time, so repositioning currently existing FDA approved drugs for treating this disastrous disease is an acceptable solution. It has been found that for SARS-CoV-2 to be infective, this necessitates splitting of the viral spike glycoproteins by the serine protease “type II transmembrane serine protease TMPRSS2” that has shown to be widely expressed in pulmonary tissues. Thus, TMPRSS2 is suggested to be potential target for antiviral drug design against COVID-19.  The mucokinetic drug “Ambroxol” has been reported as a potent inhibitor of TMPRSS2, thus it could represent a therapeutic as well as a prophylactic candidate against SARS-CoV2. This review gives a brief summary about ambroxol’s potential role against COVID-19’s TMPRSS2.                            Peer Review History: Received 8 January 2021; Revised 5 February; Accepted 25 February, Available online 15 March 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

The aim of this study was to evaluate the risk factors associated with the occurrence of caries in permanent teeth (PT) and in the permanent first molar (PFM) seven years after their eruption. Children born in 2005 who were enrolled in a Community Dental Program were included. A total of 278 children were enrolled. Evaluated risk factors were parental caries experience, educational level of the mother, routine medications, systemic diseases, dietary habits, toothbrushing frequency, existence of molar incisor hypomineralization (MIH) in the PT, and caries in the temporary teeth (TT). Associations between independent variables and the DMF-T (decayed, missing, and filled teeth in PT) and DMF-M (DMF in PFM) indices, only considering cavitated and non-cavitated carious lesions or cavitated carious lesions as outcomes, were evaluated by Poisson regression with robust variance analysis. A cariogenic diet (sweets and soft drinks), toothbrushing frequency of <1 a day, a presence of df-t (decayed and filled temporary teeth) score of >0, low educational level of the mother, and existence of MIH were associated with high DMF-T or DMF-M values (p < 0.05). We can conclude that the intake of sweets and soft drinks, toothbrushing frequency, the presence of caries in TT, and MIH in PT were the best predictors of the occurrence of caries in PT and PFM.

Abstract Objective Antibiotics misuse and a high level of antibiotics resistance is observed worldwide, but particularly in developing countries. Kosovo in the last decade is facing challenges regarding antimicrobial resistance. The purpose of the present study was to investigate patterns of antibiotics prescriptions of dentists in Kosovo's major dental clinics. Materials and Methods For Kosovo's prescribing pattern, data collection was obtained from 10 Regional Dental Clinics and a Tertiary Health Center regarding patients who were prescribed antibiotics in the years 2015 to 2019. Data analysis was performed by using descriptive statistics and was processed by using MS Excel. Results Most prescribed antibiotic during the observed period from 2015 to 2019 in Kosovo was amoxicillin, although a drastic increase of amoxicillin with clavulanic acid—as a broad-spectrum antibiotic—is observed. The trend of antibiotics use in tertiary health institutions is in an overall decrease in Kosovo with an exception in the year 2017. Despite this overall decrease, inconsistency in prescribing is observed when the pattern is analyzed for each region separately. The highest number of patients in health care dental clinics received antibiotics for maxilla-related health conditions and the lowest number of them for oncologic ones. Conclusion The patterns of antibiotics prescriptions by dental practitioners in Kosovo during the years 2015 to 2019 are fluctuating. Compared with the global health care standards, the irrational use of antibiotics in dental health care clinics in Kosovo still exist and this issue should be further addressed by respective actors.

Objectives: The aim of this study was to consider the potential association between the formation of salivary streptococcus biofilms and the incidence of caries, as well as with the occurrence of antibiotic resistance among adult mothers in Sana'a, Yemen.  Study design: A total of 261; 25-35 year old females were chosen. Clinical examination of females were performed to estimate dental caries experience with the Silness-Loe index, as well as stimulated saliva were collected to assess biofilm production by the phenotypic method i.e. Tissue culture palate methods (TCPM). Finally, antibiogram susceptibility pattern of isolated S. mutans was done by Kirby-Bauer disc diffusion method for 6  β-Lactam antibiotics (ampicillin, penicillin, amoxicillin, cefotaxime, methicillin and cefazolin) and 4 non β-Lactam antibiotics (clindamycin, erythromycin, lincomycin and vancomycin). Results: When isolated S. mutans were exposed to biofilm detection by TCP method, 31 (12.2%) showed high biofilm formation capacity, 46 (18%) showed moderate biofilm formation capacity, while 184 (72.2%) showed non / weak formation capacity of biofilm. The overall rate of biofilm formation was 30.2%. There was an escalation in the rate of formation of S. mutans biofilms with an increased degree of caries index. The S. mutans biofilms positve showed a higher rate of resistance than non/weak biofilm formation e.g ampicillin (28.6% versus 12.9%,  p = 0.002), amoxicillin (77.9% versus 18%, p <0.0001), and penicillin (79.2 % versus 23%, <0.0001) etc.  Conclusion: The present study proved that S. mutans is still the major bacteria isolate from the oral cavity, but few persons might not have significant number of S. mutans in oral cavity. The S. mutans biofilm - producers were more able to cause dental caries compared to the S. mutans biofilm-non-producers. Drug resistant factor in the S. mutans isolates was found to be associated with S. mutans biofilm formation.                           Peer Review History: Received 12 November  2020; Revised 20 Decembe; Accepted 5 January, Available online 15 January 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Background and objectives: Knowledge of the pathogenicity of the primary etiological factor of root caries, the microbial biofilm, might provide important information for the development of diagnosis and treatment strategies. This study assessed the numbers and revealed the proportion of Mutans streptococci , which is potential important cariogenic organisms, in biofilms collected from lesions at root surfaces with active caries lesions (ARC), inactive caries lesions, and sound root surfaces (SRS). Material and methods: Samples were cultured in MSB agar for Mutans streptococci counts, and brain-heart infusion agar for total viable anaerobic counts. After incubation, the number of colony-forming units (CFUs) was determined and compared between groups by the Mann-Whitney U test with a significance level set at 95%. The proportion of counts of Mutans streptococci in the total viable microorganisms was also analyzed by Chi-square test. 108 samples (36 from each surface) from 36 patients were cultured and analyzed. Results: The mean±SD for the counts of active root caries lesions was 7.47±9.89 10, significantly higher than that of inactive root caries lesions (2.5±0.97) and sound root surfaces (3.03±0.71). In conclusion, a trend towards higher counts was evident for ARC. In the ARC lesions among the dominant oral anaerobic bacteria, we could not identify streptococcal colonies (unspecified) in 11% while in IRC lesions it occurred in 47%, and SRS it occurred in 47%. In addition, in ARC the samples were ≥0.1-≥10 (CFU x10) ≥0.1-≥10 colonies of Streptococcus mutans. Conclusion: In conclusion, a trend towards higher counts was evident for ARC and for most samples, the proportion of Streptococcus mutans was low relative to the viable number of total viable anaerobic microorganisms.                   Peer Review History: Received: 5 September 2021; Revised: 10 October; Accepted: 24 October, Available online: 15 November 2021 Academic Editor:  Ahmad Najib, Universitas Muslim Indonesia,  Indones UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Complex evaluation covered health state of population residing under combined exposure to physical (noise) and chemical (manganese, formaldehyde, phenol, benzene) risk factors caused by airport activities. Findings are unacceptable chronic risks expressed through risk index for development of nervous system diseases (HI=9.45–51.75), respiratory disorders (HQ=2,62–6,95) and immune system ailments (HQ=1,75–4,23). In children, functional disorders of nervous system (parasympathetic type vegetative dystonia) and respiratory organs (chronic disorders of upper respiratory tract) are diagnosed 1,5–1,8 times higher than those in the reference group; over 5% of children aged 4–7 years demonstrate bilateral conductive deafness. Reliable cause-effect relationships were revealed between functional nervous system disorders (parasympathetic type vegetative dystonia, astheno-neurotic syndrome, vascular cephalgia, sleep disorders) and increased serum level of manganese and benzene (proportion of explained dispersion, R2=0,55–0,87, 26,44≤F≥389,54), between respiratory diseases (chronic rhinitis, chronic pharyngitis) and increased serum level of formaldehyde (R2=0,73–0,91; 350,8≤F≥778,3), with high statistic significance (p < 0,0001). For sanitary epidemiologic examination purposes, case-based reasoning for relationships of children health disorders, management decisions, the authors suggested and justified a list of parameters for negative combined impact of risk factors caused by airport hub.
