RESUMEN
OBJECTIVES: This study aimed to investigate the potential impact of arch dimensions and unerupted third molars on mandibular anterior segment crowding. MATERIALS AND METHODS: This study included a total of 240 subjects with an average age of 18 years seeking orthodontic treatment. Panoramic radiographs, alginate impressions, and study models were taken for measurements. This study utilized the Ganss ratio to calculate the ratio of retromolar space to the width of the crown of the third molar, along with other measurements such as intercanine and intermolar widths, arch perimeter, and arch length to assess dental arch dimensions. RESULTS: We found that the Ganss ratio and angle B values on both the right and left sides were significantly different between the noncrowding and crowding groups, suggesting a potential role for third molars in mandibular anterior segment crowding. Additionally, there was an increase in angle A on both sides in the crowding group, indicating a more acute angle between the anterior teeth. This study also observed a reduction in the retromolar space on the third molars in the crowding group, further supporting the potential role of third molars in mandibular anterior segment crowding. CONCLUSION: The findings of our study provide substantial evidence to suggest that third molars may contribute to mandibular anterior segment crowding. These findings highlight the importance of carefully evaluating dental arch dimensions and the presence of third molars when assessing and treating mandibular anterior segment crowding.
RESUMEN
INTRODUCTION: Edentulism and prosthodontic care are very common, especially in the elderly. The study investigated the treatment with complete dentures (CDs) and acrylic removable partial dentures (ARPDs) among people receiving new prosthodontic treatment in the Primary Health Centres of the three regions in Kosovo from 2002 to 2013. METHODS: The data on ARPDs delivery and CDs delivery was obtained from the archives of primary health centres from three Kosovo regions (Prizren, Peje, Ferizaj) from 2002 to 2013. The data was analysed concerning year of treatment, type of dentures, jaw, age, gender and urban or rural origin of the patients. The trend of treatment was determined, and the binomial logistic regression model was used for predicting odds of ARPD versus CD treatment by year of treatment and patient characteristics. RESULTS: From 2002 to 2013, 9,478 patients received 11,655 CDs and 4,401 ARPDs. Delivery of CDs significantly increased by 57.45 dentures per year (R2=0.609) and delivery of ARPDs by 30.39 dentures per year (R2=0.569). Each year the odds for ARPD versus CD increased by 4.2% (95% CI: 3.0%-5.4%). Younger patients have higher odds for ARPD rather than CD and odds for ARPD are decreasing as the age of patients rises. The gender, residence, and jaw all had a significant impact on prosthodontic treatment too. CONCLUSIONS: In Primary Health Centres of Kosovo, there is a trend for higher frequencies of both dentures (more obvious for ARPD), and the frequency is highly dependent on the age of patients.
