To minimize the incidence of cross-infection prior to bonding an invitro study was done to assess the antibacterial activity of chlorhexidine, povidone iodine and glutaraldehyde.\u0000Aim: To compare the antibacterial activity of 2% chlorhexidine, 5% povidone iodine and 2% glutaraldehyde on orthodontic materials prior to bonding.\u0000Materials and methods: A total of 36 samples were included in this  study. The main group consists of 3 disinfectants and one control group (n =4). Group -1(Chlorhexidine gluconate), Group - 2 (Povidone Iodine), Group - 3 (Glutaraldehyde) and Group - 4 (Control group –untreated). Each group consists of 3 subgroups of the tested samples namely group A (brackets), group B (archwires) and group C - molar bands (n=9). which were contaminated by 3 bacterial species streptococcus, staphylococcus, lactobacillus and the number of colonies were counted before disinfection. The contaminated samples were subjected to disinfection with 2% chlorhexidine for 5 minutes 2% glutaraldehyde and 5% Povidone Iodine for 10 minutes. 20µl of sample of the disinfected samples were incubated and the number of colonies were counted after disinfection.\u0000Results: There were no colonies formed when 5% Povidone iodine was used to disinfect archwires and molarbands in few tested samples. 2% glutaraldehyde and 2% chlorhexidine were not effective against lactobacillus species. Povidone iodine was effective when compared to glutaraldehyde and chlorhexidine gluconate and effective against all the three species namely Streptococcus, Staphylococcus and Lactobacilli species. The obtained p-value is < 0.001 which is statistically significant when all groups were compared overall.\u0000Conclusion: Disinfection with 5% povidone iodine was most effective when compared with 2% chlorhexidine and 2% glutaraldehyde.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47438689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On extra oral examination, she had convex profile with posterior divergence and interlabial gap of 10mm and everted upper lip. The patient had a gummy smile of 8mm. Intra orally, she had Class II canine relationship on both sides with missing irt 16, 36, 46. Cephalometric values showed Class II skeletal base with protrusive upper and lower incisors and acute nasolabial angle. Initially orthodontic treatment was done and extraction of upper first premolars was planned during surgery. AMO was done with superior impaction of 4mm and posteriorly by 6mm. After 4 weeks of post surgery, the settling of occlusion using intermaxillary elastics was done. At the end of the treatment, the patient had Class I canine relationship on both sides with Skeletal Class I and overjet and overbite was 2mm. The patient gummy smile was reduced to 4mm which was accepted by the patient. Fixed retention was given in both the arches. The total treatment time was around 30 months. \u0000Conclusion: The proper diagnosis and appropriate treatment planning is the main key to achieve stable results in Orthodontics.

The SFA protocol utilizes the dentoalveolar compensations as an advantage to effect immediate facial changes, which in conjunction with the Regional Acceleratory Phenomenon enhances the tooth movement thereby reducing the total treatment duration. The post-surgical orthodontic phase is often complicated by rapid accelerated tooth movement producing a non-predictable nature of tooth movements. With the combined application of temporary anchorage devices these movements are made predictable in three dimensions. This case report illustrates the treatment of a skeletal Class II patient with a combination of the SFA protocol and TAD aided orthodontic treatment. A 19-year-old female presented with proclined upper anteriors and retrusive lower jaw. Clinical examination revealed a severe lip incompetency, mandibular deficiency, Class II skeletal malocclusion, severe bimaxillary incisor proclination, severely crowded mandibular arch on a low mandibular plane angle. The SFA protocol involving BSSO advancement and genioplasty was performed, followed by an orthodontic phase involving TADs. The total treatment time was 14 months, following which excellent facial change and stable occlusion was achieved.

Secondarily, to analyze the relationship between those factors.\u0000Methods: Pre- and post-treatment cephalograms of 89 patients treated with extraction of four bicuspids or two maxillary bicuspids were analyzed. The sample was divided into three groups based on their facial pattern measured by SN-MP angle (hypodivergent: < 270, hyperdivergent: >380, and normodivergent: 270-380). Linear and angular measurements included the distances of U1 tip and U6 mesial height of contour to Y-axis (i.e., line perpendicular to the X-axis, passing through Sella turcica), distance of U1 tip to Sella on X-axis, overbite, angulation of U1 to palatal plane, and SN-MP and ANB angles. Inferential statistics included one-way ANOVA, Chi-square test, independent t-test, and Pearson’s correlation coefficients.\u0000Results: Facial morphology did not primarily affect anchorage loss, because other factors such as crowding, severity of Class II molar relationship, and extraction modality played more impactful role (P< 0.01). Change in mandibular plane angle was neither influenced by, nor correlated with, initial facial morphology or anchorage loss (P> 0.05). Positive change in overbite was significantly correlated with facial pattern, incisor extrusion and retroclination (r= 0.30, 0.44, and -0.35, respectively, P< 0.01).\u0000Conclusion: Anchorage loss in extraction orthodontic treatment is not influenced primarily by initial facial morphology. Anchorage loss is not significantly associated with MP angle reduction.
