RESUMO
Background & Objective: Lingual orthodontics is gaining more popularity in orthodontic centers. The purpose of present study is to evaluate changes in the oral cavity with lingual orthodontic appliances. Methodology: The epidemiological study was conducted among 45 patients with lingual orthodontics. Before the start of orthodontic treatment all the patients received proper oral prophylaxis. The incidence of White Spot Lesions (WSLs), plaque accumulation and gingivitis were evaluated at the interval of one, six and twelve months using WSL index developed by Gorelick et al., (1982), Silness & Löe plaque index and Löe & Silness gingival index respectively. The Student’s t test and ANOVA test were used with a significance level of 5%. Results: The frequency of WSLs increased with the procedure of lingual orthodontics from first month (3.2%) to six (6.7%) and twelve months (7.9%). A significant increase in the plaque index (PI) and gingival index (GI) was observed from month one to twelve months. Overall mean of PI and GI was 2.07±0.809 and 1.67±0.929 respectively among the patients. Conclusion: The occurrence of dental plaque and gingival inflammation was mostly noticed in lingual orthodontic cases as it is difficult to remove the plaque deposits around the brackets in the lingual side.
RESUMO
Aim: The aim of the study was to determine the prevalence of anterior teeth fracture among visually impaired individuals. Materials and Methods: A cross‑sectional study was carried out among 103 blind individuals (70 males and 33 females), with age ranges from 10 years to 29 years, the survey was carried out according to World Health Organization (WHO) criteria and by using WHO classification for teeth fracture. All subjects were divided into two groups on the basis of whether they are partially sighted or totally blind. Data were analyzed using Chi‑square test, with keeping the level of significance at P < 0.05. Results: Overall prevalence of 34.95% of traumatic injuries to anterior teeth was found in the study population with no significant difference between both groups (P < 0.05). Female were having significantly more fracture than males (P < 0.005). Fall being indoor was the most common cause. Permanent maxillary central incisors were most commonly injured with injuries involving enamel and dentin being the most frequently observed. Increased overjet and inadequate lip coverage were significantly associated with the occurrence of trauma (P = 0.0001). Conclusion: The prevalence of dental injuries in a group of individuals with blind. This should alert caregivers to carry out a profound investigation of the events and suggest methods to reduce this type of morbidity.
