Effect of Timing of Third Molar Extraction on the Rate of Mandibular En Masse Distalization Using Buccal Shelf Implants – A Randomized Controlled Trial

This randomized controlled trial evaluates the impact of the timing of third molar extractions on the rate of mandibular en masse distalization and second molar angulation in orthodontic treatment, using buccal shelf implants in borderline Class III malocclusion patients. Late third molar extractions performed less than two weeks before distalization were compared to early extractions, performed six months prior, to investigate the effect of Regional Acceleratory Phenomenon (RAP) on tooth movement. The study also assessed second molar angulation changes, examining distal tipping differences between groups. Results showed a significantly faster rate of distalization in Group II (late extraction) at 0.637 ± 0.098 mm/month, compared to Group I (early extraction) at 0.422 ± 0.075 mm/month. Additionally, Group I experienced significantly greater second molar distal tipping (9.14°) than Group II (3.47°). These findings suggest that the timing of third molar extractions affects both distalization rates and second molar angulation, with early extraction offering a clinical advantage by leveraging RAP and minimizing undesirable tipping

Caries Risk Among 15-40 Years Old Patients Visiting Private Dental Institution - A Retrospective Study

Various models for predicting caries risk have been developed with good results. One such recently developed model is Cariogram. Cariogram systematize the evaluation of various risk factors for caries and recommend targeted preventive intervention based on caries risk. The aim of this study was to evaluate the caries risk among 15-40 years adults in Chennai. A retrospective study was conducted using records of patients visiting private dental college during the month of Feb 2020 to March 2020. A total of 112 case records were retrieved and analysed. Descriptive statistics in terms of frequency distribution was done to present the result. Mean chance to avoid caries was high in 36-40 years (57.8±27.1). Mean bacterial count was high for in the age group 31-35 years (14.6±7.153). Mean susceptibility was high among 21-25 years(23.6±18.8). Mean diet sector was high among 31-35 years(11.6±5.66). The association of age and chances to avoid new caries was p=0.119, circumstances was p=0.386; bacterial sector was p=0.919; susceptibility was p value=0.358 and diet was p=0.513 which was found to be statistically not significant. Males and females of age group 31-35 years have high risk for caries. Young adults have higher risk for caries with no association between age and all five components of cariogram

Vacuum-Formed Retainers Versus Lingual-Bonded Retainers: A Systematic Review and Meta-Analysis of Stability of Treatment Outcomes in Orthodontically Treated Patients

Objective:This review aimed at analyzing the literature comparing vacuum-formed retainers and lingual-bonded retainers for maintaining treatment stability and periodontal health and evaluating retainer failure and patient satisfaction.Methods:Electronic databases such as PubMed, Cochrane Library, Ovid, Scopus, Web of Science, and Google Scholar were searched. Only randomized controlled trials were involved. Risk of bias was evaluated using Risk of Bias 2 Tool. Meta-analysis was performed and certainty of evidence was assessed with Grading of Recommendations Assessment, Development, and Evaluation approach.Results:Five randomized controlled trials were included for qualitative analysis and 2 studies were included for quantitative analysis. Two studies concluded that lingual-bonded retainers were more effective than vacuum-formed retainers in maintaining treatment stability. Two studies had a high risk of bias and 3 studies had some concerns. No statistically significant difference in Little’s Irregularity Index (standard mean difference = −0.10; P value = .61), inter-canine width (standard mean difference = 0.66; P value = .09), inter-molar width (standard mean difference = 0.08; P value = .85), arch length (standard mean difference = −0.18; P value = .60) between the 2 retainers was noted. Periodontal status and retainer failure rate (odds ratio= 2.28; P value = .23) were similar in both retainers. Patient discomfort, soreness, and speech difficulty were more with vacuum-formed retainers and oral hygiene maintenance was easier with vacuum-formed retainers.Conclusion:A very low-level certainty of evidence suggests that both vacuum-formed retainers and lingual-bonded retainers were equally effective in maintaining treatment stability. Periodontal status and retainer failures were similar in both retainers. Vacuum- formed retainers were better for oral hygiene maintenance but were associated with discomfort, soreness, and speech difficulty than lingual-bonded retainers

Comparison of salivary parameters in orthodontic patients with good oral hygiene and bad oral hygiene: An-ex vivo study

Aim: The aim of the study is to compare the salivary Ph, Buffer capacity, calcium, phosphorus and urea levels in clean and unclean mouths of orthodontic patients. Materials and methods: This ex-vivo study was carried out in orthodontic patients. 40 (group 1: clean mouth; group 2: unclean mouth) patients were included in this study. Unstimulated saliva was collected from both groups using a draining method and was subjected to chemical analysis. Results: Intergroup comparison between clean and unclean mouth revealed that Ph, Buffer capacity, Calcium, phosphorus levels reduced significantly in the unclean mouth as compared to clean mouth patients . Urea levels significantly increased in the unclean mouth group. (p<0.05). There was no statistically significant difference between males and females in both groups. Conclusion: Patients undergoing orthodontic treatment have altered chemical salivary parameters. Patients having OHI index levels more than 3, i.e. unclean mouth patients have reduced pH, buffer capacity, calcium and phosphorus levels and increased urea levels in saliva as compared to orthodontic patients having clean mouths

Knowledge, awareness and practice of digital study models and conventional study models among orthodontists and post-graduate students: A cross sectional pilot survey

Introduction: Digital study models today, provide the state-of-art infrastructure for the diagnosis and treatment planning in orthodontic malocclusions. Its versatility and wide scope of application makes it a valuable alternative to conventional study models. However, affordability and lack of knowledge may be the reasons for its limited use, presently. Hence, it was aimed to assess the knowledge, awareness and practice of digital and conventional study models among orthodontists and post-graduate students. Methods: A close-ended self-constructed questionnaire comprising of fifteen questions was administered to 50 orthotists and 50 post-graduate students. Frequency distribution of the answers given by the participants in each domain (knowledge, awareness and practice) was presented graphically. Results: The orthodontists had a better understanding and also were more inclined to digital study model as compared to the post-graduates. Storage and sterilization are the main concerns addressed by the digital study model, whereas conventional study models still remain less expensive. Conclusion: Orthodontists as well as post-graduates possess sufficient knowledge about digital study models, with orthodontists having a slight edge over the post-graduate students

A Systematic review on aligning efficiency of superelastic NITI: in comparison with conventional NITI and multistranded stainless steel archwires

Background: The initial leveling and aligning phase of orthodontic treatment involve the use of nickel titanium wires. The nickel titanium wires exhibit unique properties like shape memory and superelasticity. In the beginning, conventional nitinol wires were used, which lacked the superelastic property. Nowadays, superelastic nickel titanium wires are being used commonly. This systematic review aims to evaluate the efficiency of Superelastic NITi in the initial alignment of orthodontic treatment in comparison with conventional NiTi and multistranded stainless steel archwires by measuring the amount of decrowding and the time taken for decrowding.Method: A systematic literature search was performed on Pubmed, Cochrane, Google scholar &amp; Lilacs.Result: Thirty four studies were identified by the search and ten studies satisfied the inclusion criteria and one study was excluded after abstract reading. Finally nine articles were included for quality assessment.Conclusion: This systematic review concluded that there was no significant differences in the aligning efficiency of superelastic NiTi in comparison with conventional NiTi and multistranded stainless steel wires. </jats:p

Periodontally Accelerated Osteogenic Orthodontics (PAOO) Assisted Management of Palatally Impacted Canine with Five Years Follow Up

Periodontally Accelerated Osteogenic Orthodontics (PAOO), a patented technique by the Wilcko brothers has become very popular in reducing the treatment time in Orthodontics. A 17-year-old male patient presented to the Department with a Class I skeletal and a Class I dental pattern with bilateral canine impactions. The canine impaction was buccal on the right side (13) and palatal on the left side (23). The initial treatment plan was to disimpact 13 with a piggy back wire and 23 using the K9 spring respectively and it did not involve the PAOO Technique. However, six months into treatment, the patient stopped reporting for his regular appointments and reported after a time interval of one and a half years to continue his treatment. At the time of his return, considerable bone loss around the region of 23 was noticed on radiographs. The PAOO technique was therefore, carried out to augment bone around 23 as well as reduce the time for treatment
