Objective. The goal of this review was to determine the effectiveness of different types of monobloc and bibloc mandibular advancement device (MAD) devices in the treatment of all forms of obstructive sleep apnea (OSA), by reviewing the available literature. Methods. A systematic literature search was performed in PubMed, ResearchGate, NCBI and Google Scholar databases. The search included articles in English, published in the inclusive time period from 2000 to 2024. Results. A total of 13 studies were analyzed that directly compared the effectiveness of monobloc and bibloc devices. The studies were published in the period from 2000 to 2024, and included crossover and parallel randomized controlled trials, as well as cross and parallel cohort studies. Out of the 13 studies, four were classified as RCT parallel studies, six were RCT crossover studies, two cohort parallel studies, and one cohort crossover study. The duration of the studies was variable, ranging from four weeks to one year, with six studies having a so-called “washout period” between the use of monobloc and bibloc MAD devices. Conclusion. Both monobloc and bibloc devices show significant success rates in the treatment of mild to moderate OSA.

Background/Aim: The aim of this study was to determine the accuracy of overall and anterior Bolton's ratio measurements obtained with an intraoral scanner compared to standard caliper measurements on plaster models. Material and Methods: This study included 33 subjects (18 female and 15 male), aged 12 to 18 years. All subjects were taken impression for the purpose of making study plaster models. In addition, all subjects underwent intraoral scanning for the purpose of creating digital models. Tooth width was measured with a caliper on plaster models, while digital models were analyzed using Cerec Ortho SW 2.0.2 software. The overall and anterior Bolton ratios were derived using both methods. Statistical data processing was performed using an independent t-test. Results: The results obtained using these two methods for measuring the anterior and overall Bolton ratio showed that there was no statistically significant difference in the measurements obtained on plaster models and the measurements obtained by intraoral scanning. For the overall Bolton ratio, T-test was 0.828 and is not statistically significant (p<0.05). The value of T-test for the anterior Bolton ratio was 0.001 and it was also not statistically significant (p<0.05). Conclusions: Determination the overall and anterior Bolton ratio using an intraoral scanner is an accurate and acceptable method for clinical work in orthodontics.

Background/Aim: The aim of the research is to assess the psychosocial impact of malocclusion, to determine the relationship with the degree of need for orthodontic treatment, and to assess the influence of gender on this relationship in adolescents. Material and Methods: A total of 100 subjects, aged 12 to 18, participated in the research. The subjects had no previous orthodontic treatment. The assessment of the need for orthodontic treatment was performed using the Index of Orthodontic Treatment Need (IOTN), namely the Dental Health Component (DHC) and the Aesthetic Component (AC). The psychosocial impact of dental aesthetics was assessed using the PIDAQ questionnaire. Results: The total PIDAQ score, as well as its 4 subclasses, dental self-confidence, psychological impact, social impact and aesthetic concern have a positive correlation with the categories of the IOTN. The psychosocial impact of dental aesthetics is similar in boys and girls, except that girls showed a slightly greater aesthetic concern due to the presence of malocclusion. Conclusions: The present malocclusion has a psychological and social impact on the individual, but it also negatively affects his dental self-confidence and aesthetic concerns. The results of the PIDAQ questionnaire can guide the orthodontist to the patient's basic problem and thus provide guidelines for orthodontic treatment.

Background/Aim: The objective of this research was to evaluate the level of oral hygiene, the prevalence of caries, and the condition of the soft tissues in children and adolescents referred for their first orthodontic examination. Material and Methods: The research was conducted at the Department of Orthodontics of Sarajevo University - at the Faculty of Dentistry with the Dental Clinical Center. A total of 300 patients with mixed and permanent dentition who were referred for their first orthodontic examination were included in the study. The patients were offered to sign a Letter of Informed Consent for this study. All patients were assigned a Decayed, Missing, and Filled Teeth (dmft/DMFT) index. Periodontal indices were evaluated on all first permanent molars and all permanent central incisors. The periodontal indices included the determination of PI,CI,GI, PBI. Results: The results were processed with the application of standard statistical methods, by using the SPSS computer program for statistical analyses (SPSS-Statistical Package for Social Sciences) Version 21.0. The results of this study show a high dmft and DMFT indices in patients referred for orthodontic examination. The dmft index value in the respondents with mixed dentition was 3.0 (1.0 - 6.0). The DMFT index value in the respondents with permanent dentition was 4.0 (0.0 - 6.0), while in the respondents with mixed dentition, it was 1.0 (0.0 - 3.0). Our research also shows that out of 300 patients referred to an orthodontist for their first orthodontic examination, 250 of them (83.33%) have demonstrated an increased value of the Plaque index. Conclusions: The results of this research should be peculiarly alarming for pedodontists and general dentists, cautioning them to implement caries prevention measures more intensively and make referrals to an orthodontist only in case of those patients who have been cured previously.

INTRODUCTION:Obstructive Sleep Apnea (OSA)represents the complete or partial obstruction of the airway.Clinically OSA manifests as sleepness during the day,heavy snoring as well as waking up during the night dues the lack of air.Obesity,gender and orthodontic malocclusion are mentioned in the literature as the etiologic factor for Obstructive Sleep Apnea. AIM: The aim of this study was to find the relationship in the analyzed studies between the Obstructive Sleep Apnea and orthodontic malocclusion at non-obese adults. MATERIAL AND METHODS:The electornic search of the database was performed,using PubMed and Googlescholar,with the aim to find the relevante articles which correlate the OSA and orthodontic malocclusion.Keyword included:obstrucitve sleep apnea,orthodontic malocclusion,cephalometric analysis,impact,association,body mass index,obesity,adults,non obesity. Inclusion criteria were:nonobesity,orthodontic malocclusion,adults,articles published from 1999 to 2019,articles in English,full articles avaiable. RESULTS:Two hundred papers included keywords.The number of articles that included the fully set criteria was nine.These nine articles were analyzed in detail. CONCLUSION:Analyzed articles showed that there is relationship between the Obstructive Sleep Apnea and orthodontic malocclusion in non-obese adults.It was also showed that orthodontic malocclusion is etiological factor for OSA in non-obese adults.

Introduction: Obstructive sleep apnea (OSA) is characterized by the cessation of air flow during sleep due to an obstruction in the nasopharyngeal/oropharyngeal region. The consequences that untreated obstructive sleep apnoea might have on patient’s health include symptoms like sudden awakening with a sensation of suffocation, morning headache, daytime sleepiness and fatigue, lack of concentration, and it is commonly connected to hypertension, coronary artery disease, depression, obesity and other medical conditions. Aim: The purpose of this review study is to enlighten the role of an orthodontic professional in prevention and treatment of obstructive sleep apnea syndrome to the general public. Methods: Data search was determined by the following keywords: sleep apnea, orthodontic abnormalities, orthodontic prevention, sleep apnea syndrome, obstructive sleep apnea, cephalometric analysis, AHI index, BMI index and obesity. Electronic data search was performed on platforms Pubmed and Google Scholar. Results: After reading and analyses, twenty-one articles with similar procedural criteria were selected, and among them only 6 were recognized as meeting the criteria of being completely accessible, having the selected keywords in their name, using the cephalometric analysis and BMI index and discussing the obese adults sleep apnea. In all the examined studies, it is proven that craniofacial morphology is a major anatomical risk factor for OSA. Conclusion: The role of the orthodontic specialists might be crucial in prevention of the development of obstructive sleep apnea, not only considering the orthodontic devices treament options, it can be especially important when obesity appears as a factor in the sense of informing and advising the patient and cooperating with other specialists who treat and prevent obstructive sleep apnea syndrome.

AIM Research aimed to gather aepidemiological parameters of MIH from a sample of Sarajevo children born between the years 1999 and 2003. Prevalence of MIH, distribution according to severity (mild vs. moderate/severe cases) and distribution according to phenotypes (MIH vs MH) were investigated. MATERIALS AND METHODS Study design: This was a cross-sectional, observational, aepidemiological study that was conducted on a sample of 446 children aged 6 to 9 years. It was conducted as a part of regular dental screening of children attending a randomly selected primary school in the Bosnian capital city of Sarajevo. RESULTS The overall prevalence of MIH was 11.5%. MIH prevalence varied between 19.9% of examinees born in year 2002 to 8.4% among those born in 2003. Number of teeth affected varied from 1 to 7. The average number of affected teeth was 3.82 ± 1.46. Demarcated opacities were recorded on 13.89%, post-eruptive enamel breakdown on 11.28% and atypical filling on 6.2% index teeth. Mild cases of MIH were rare in our sample, 18% of subject had only demarcated opacities present. A smaller percentage of examinees (35.3%) had hypomineralisation present only on first permanent molars (MH group). Out of 64.7% of subjects in MIH group, 37.25% had one incisor affected and 21.57% had two incisors affected. CONCLUSION Over 80% of study subjects with MIH were categorised as moderate/severe case of MIH and they represent a major problem with regards to dental treatment. It is necessary to plan a multi-disciplinary approach for dental care of this population. It is necessary to educate primary care dentists to recognise this condition and provide recommended treatment to patients with mild clinical picture, while directing those with more severe problems to specialised doctors.

Abstract Objective The aim of this research was to examine the attitudes and perceptions of dentofacial aesthetics among different age groups. Materials and Methods The sample consisted of elementary-school students from the city of Sarajevo, Bosnia and Herzegovina, and their parents. This study included 314 subjects: 157 children and 157 parents. The children’s group consisted of 85 (54.14%) males and 72 (45.85%) females, aged 9 to 15 years. Statistical Analysis Descriptive statistics were used to determine frequency distribution and percentages for all variables. A chi-squared (x 2) test was used to determine the association between variables and a p-value < 0.05 was considered significant for all the differences and associations. Results For the dentofacial appearance with no teeth irregularity or with severe teeth irregularity, an analysis of variance (ANOVA) (post-hoc tests—Tukey’s HSD) indicated that the difference is not statistically significant (p = 0.06) relative to rank matching between all three subject groups. For dentofacial appearance with mild teeth irregularity, an ANOVA (post-hoc tests—Tukey’s HSD) showed statistical difference (p = 0.07) between the teenage group of subjects relative to pre-teenage group of subjects and adult group of subjects. Conclusion Attitudes about desirable and acceptable dental aesthetics differ in younger children compared with older children and parents. Ten years old children find good function with poor aesthetics more pleasing, while 14 years old children find aesthetics with bad function as more pleasing.

Retention is a phase of orthodontic treatment devised to keep the teeth in a correct position once the orthodontic treatment has been completed. There are three main characteristics that each ideal retainer is required to have: to keep the teeth in the correct position after orthodontic therapy, to be long lasting and resistant to mechanical damage, and to have no adverse long-term effects on periodontal tissue. Through a computer-based browsing through a number of databases (such as, e.g. PubMed and Google Scholar) we have found and analysed various articles used in this research. The inclusion criteria to be met were: an overall availability of a research paper, the requirement that these research papers are published in English, that these research papers were published in the period 2007-2019, the requirement that the research papers should involve clinically randomized studies and that their titles contain one of the predefined keywords. The database browsing that is based on the said keywords and carried out within the above time frame has resulted in finding 165 relevant articles. A complete set of the inclusion criteria were met by 8 published research papers, but 7 articles were analysed in the end. The selected articles have compared different types of fixed and mobile retainers, different times of wearing the retainers, the impact that the retainers had on the periodontium, and the acceptability of different retention protocols for patients. The conclusion of this research paper is that bonded retainers prove to be most effective in stabilising the position of the incisors, particularly the lower ones, but that their disadvantages include the reopening of the extraction space and the retention of plaque due to difficulties in maintaining oral hygiene. Vacuum-formed retainers appear to be more effective than Hawley retainers in retaining the position of the incisors, and patients have indicated that they are more acceptable to wear. Hawley retainers prove to be most effective in preserving a closed extraction space, but they do now show solid results with regard to other segments. Changes in the overbite, overjet, arch length, and anterior and posterior widths did not show any significant statistical differences in the different types of retainers.   Keywords: orthodontics, retention, stability, impact
