ABSTRACT Purpose: To quantify the prevalence of white spot lesions (WSLs) on anterior teeth and, secondarily, to evaluate risk factors and predictors. Materials Methods: Digital photographs records 885 randomly chosen patients were evaluated before after treatment. Chart information included gender, age, as well banding debanding dates. Fluorosis oral hygiene treatment also evaluated. Preexisting posttreatment WSLs recorded compared for all 12 teeth. Risk ratios (RR) absolute (AR) calculated...

This purpose of this study was to evaluate the largely untested assumption that malocclusion negatively affects masticatory performance. A sample 185 untreated subjects (48% male and 52% female) from 7 37 years age, representing with normal occlusion (n = 38), Class I 56), II 45), III 46) malocclusion, were evaluated. Masticatory performance evaluated objectively using artificial (CutterSil, median particle size broadness distribution) real foods (number chews for jerky almonds),...

To evaluate the Forsus Fatigue Resistant Device (FRD) as a compliance-free alternative to Class II elastics.A sample of 34 (14 female, 20 male) consecutively treated nonextraction FRD patients (12.6 years age) were matched with elastics (12.2 based on four pretreatment variables (ANB, L1-GoMe, SN-GoMe, and treatment duration). Pretreatment posttreatment cephalometric radiographs traced analyzed using pitchfork analysis vertical analysis. t-Tests used group differences. Group differences...

ABSTRACT Objective: To evaluate differences in discomfort levels between patients treated with aligners and traditional fixed orthodontic appliances. Materials Methods: This blinded, prospective, randomized equivalence two-arm parallel trial allocated 41 adult Class I nonextraction to either appliance (6 males 12 females) or aligner (11 treatment. Patients completed daily diaries following their initial treatment appointment, after 1 month 2 months. They recorded of at rest, while chewing,...

ABSTRACT Objective: To compare the time efficiency of aligner therapy (ALT) and conventional edgewise braces (CEB) based on large samples patients treated by same highly experienced orthodontist, with treatment goals for both groups patients. Materials Methods: The retrospective portion study evaluated 150 CEB who were matched, mandibular crowding number rotated teeth, to ALT All records obtained at one orthodontist's office. had mild-to-moderate Class I malocclusions (≤5 mm incisor...

This study investigated how jaw kinematics, including cycle duration, three‐dimensional (3‐D) excursive ranges and velocities, shape, changed with increasing hardness of chewing gum. Twenty‐six subjects (13 males 13 females; mean age 23·6 ± 2·5 years) Class I normal occlusion were asked to chew two brands gum differing hardness. Jaw motion during was tracked an Optotrak ® camera at 100 Hz, all movements recorded as pure 3‐D mandibular relative Frankfort horizontal. Cycle duration did not...

The aim of this study was to assess the impact various sized buccal corridors (BCs) on smile attractiveness. One female smiling photograph, displaying first molar (M1-M1), digitally altered produce (1) smiles that filled 84, 88, 92, 96, and 100 per cent oral aperture; (2) second premolar (PM2-PM2) 96 (3) with asymmetrical BC 90, 94, aperture. 18 produced were evaluated by 82 orthodontists (70 males 12 females) 94 laypeople (40 54 females). Paired t-tests used evaluate differences within...

This study correlated maximum bite force and masticatory muscle electromyography (EMG) activity with craniofacial morphology mechanical advantage of children vertical growth patterns. From lateral cephalograms 30 females 17 males (9.3 +/- 3.6 years age), 13 morphological eight biomechanical measurements were recorded. Two forces 12 submaximal along their associated EMG recorded at the right mandibular first molar. Muscle efficiency was evaluated using relationship between levels. There no...

Abstract Aim To compare ibuprofen, to an ibuprofen/acetaminophen combination in managing postoperative pain following root canal treatment. It is hypothesized that the drug will provide more relief than placebo or ibuprofen alone. Methodology Patients presenting at Texas A&M Baylor College of Dentistry's graduate endodontic clinic, experiencing moderate severe pain, were considered potential candidates. Fifty‐seven patients included based on established criteria. Following administration...

It is not fully understood whether masticatory performance compromised in individuals with the more common forms of malocclusion (i.e. Class I and II). The aim this prospective investigation was to establish relationships between performance, (type severity), age, body size gender, children adolescents. A total 335 were examined at average ages 6, 9, 12 15 years. Each subject's occlusal status described by Angle classification Peer Assessment Ratio (PAR) index. Masticatory quantified median...

SummaryAnthropometric asymmetry was considered in a sample of 202 normal and about 200 mentally retarded males. In addition to height, 11 bilateral measurements bone, soft tissue strength were taken. Differences between analysed terms absolute signed differences, the differences corrected for height. Mentally individuals show greater anthropometric than both those The distributions signed, are also broader retarded, variances left-right associated with measurement. Left-right males occur...
