Efficacy of Low-level Laser Therapy in Increasing the Rate of Orthodontic Tooth Movement: A Randomized Control Clinical Trial

World Journal of Dentistry (2019)

Chethan K Dakshina Srinivasa Hanumanthaiah Prasanna T Ramaiah Tobin Thomas Jibin K Sabu

Aim:The aim of the present study was to assess the effect of low level laser therapy in increasing the rate of orthodontic tooth movement.Materials and methods: Twenty-four arches in 24 patients above 18 years of age requiring bilateral extractions in the same arch were randomly selected for this study.By this way, both the patient and the postgraduate student were blinded in the study.The experimental side was exposed to biostimulation using 980 nm gallium-aluminum-arsenide (GaAlAs) diode lasers, and the contralateral side was taken as control.Laser irradiation was delivered with a power output of 2 W in a continuous wave mode.The laser beam was delivered using a 1 × 4 cm diameter tip held perpendicular and in contact with the mucosa at the cervical third of canine on the buccal and palatal surfaces over an area of 4 cm 2 .Digital caliper measurements accurate to ±0.001 mm were recorded on study cast models on the 1st day, 28th day, 57th day, and 85th day.The distance between the contact points of the maxillary canine and second premolar was measured on study cast models three times, and the mean value was used for data computations.Results: On comparison of the rate of tooth movement between the control and laser groups, the tooth movement was greater in the laser group than in the control group, and it was statistically highly significant at all time intervals with the level of significance set at 0.05 at 95% confidence interval.Conclusion: LLLT with a specified regimen applied once in a month is effective in increasing the rate of orthodontic tooth movement.

A heuristic model for cephalometric diagnosis of sagittal dysplasia

Journal of Orthodontics (2021)

Objective: To identify the best-suited cephalometric parameter for assessing the sagittal skeletal discrepancy in the Indian population. Design: An in vitro, observational, single-blinded, retrospective study. Setting: Department of Orthodontics and Dentofacial Orthopaedics. Methods: A total of 94 lateral cephalograms were used in this study. The study involved one key person and two examiners. The key person collected the radiographs, coded, analysed and classified them into three groups (skeletal classes I, II and III). Subsequently, the coded radiographs were independently analysed by the two examiners. They classified the cases by matching a minimum of 6 out of 11 parameters. On completion of diagnosis by the examiners, the samples were decoded and matched with the original diagnosis given by the key person. The samples in which identification of a particular cephalometric parameter matched the original evaluation as given by the key person was regarded as correctly diagnosed. The number of correctly assessed cases was used to judge the diagnostic performance of all the parameters in all the cases. Cross-validation of the method was performed, and a diagnostic algorithm was developed for diagnosis. Results: β angle and Pi angle showed a positive predictive value of 1 in both skeletal class I and II cases. ANB angle, W angle and HBN angle showed a positive predictive value of 1 in skeletal class III cases. Conclusion: No single cephalometric parameter can independently be used to diagnose sagittal skeletal discrepancy in all cases. However, a conclusive diagnosis on the type of sagittal skeletal malocclusion can be made by using a simple and easy to use diagnostic algorithmic process having a combination of cephalometric parameters.

Prediction of Mandibular Growth Pattern Using Palatoscopy: A Retrospective Model Analysis

The Journal of Contemporary Dental Practice (2021)

Chethan K Dakshina Prasanna T Ramaiah Swaroop Subramonia Suhas Setty Mayank Khandelwal

Aim and objective: To predict and correlate mandibular growth pattern using palatoscopy (average, horizontal, and vertical).Materials and methods: This retrospective study includes 120 archived maxillary casts.One key person and two examiners performed the study; the key person was responsible for coding and collecting casts and radiographs, as well as calibration of the examiners.The key person divided the samples into three craniofacial growth pattern groups (average, horizontal, and vertical) based on Frankfort-mandibular plane angle (FMA), SN-GoGn, and facial axis angle and distributed them to the blinded examiners.Rugae were studied using a modified Thomas and Kotze classification system.After the analysis, the results were decoded and analyzed with the corresponding cephalometric radiographs.Results: Multinomial logistic regression was employed to predict the mandibular growth patterns with the following independent variables: Forwardly directed rugae, number of divergent rugae, predominant shape circular, predominant shape curved, primary rugae, predominant shape wavy, number of convergent rugae, and horizontally directed rugae.Conclusion: Palatal rugae patterns predict the growth pattern of the mandible.Clinical significance: Considering the significant parameters and their correlation with mandibular growth pattern, prediction of mandibular growth patterns can be done noninvasively.

Use of Single-dose Low-level Laser Therapy for Pain Control on Initial Archwire Activation of Orthodontic Appliance: A Randomized Control Clinical Trial

World Journal of Dentistry (2019)

Chethan K Dakshina Srinivasa Hanumanthaiah Prasanna T Ramaiah Jibin K Sabu Swaroop Subramonia

Aim: To compare and evaluate the relative analgesic efficacy of low-level single-dose laser and placebo irradiation after the placement of the first arch wire (0.016 inch Ni-Ti wire) at 6, 12, 24, 36, 48, and 72 hours using a visual analog scale (VAS).Materials and methods: Fifteen maxillary arches of 15 patients were selected for the study.All the brackets and molar tubes were bonded and 0.016-inch nickel-titanium wire was inserted and ligated to the bracket using 0.009 inch stainless steel wire.After performing the orthodontic procedures, a low-level laser therapy (LLLT) of wavelength of 980 nm an output of 2 W with an energy density of 40 J/cm 2 side, and an application dose of 10 J/cm 2 were applied on the buccal and palatal sides of each tooth for 20 seconds, respectively.The laser beam was placed for the control group on the contralateral side for the same extent of time but in the switched off mode.Patients were asked to assess the pain at home at 6, 12, 24, 36, 48, and 72 hours after irradiation using a VAS.Results: In both the groups, pain increased during the first 12 hours and gradually decreased over the next couple of days.The peak of pain was maximum at 12 hours post irradiation in both the groups.There was a statistically significant (p < 0.005) reduction in pain in the experimental group than the control group at all-time intervals.Conclusion: LLLT significantly reduces orthodontic tooth pain due to the initial archwire activation.
