Carpet-Layer's Knee

In order to reveal abnormalities in the soft tissue of the anterior part of the knee, caused by protracted mechanical stress, we performed ultrasound studies of both knees of 95 male workers in the carpet-laying and parquet floor trade (group 1). Seventy-three painters (group 2) served as controls. In group 1, an anechoic fluid collection was detected in 10 knees, localized in the superficial infrapatellar bursa and in one patient in the prepatellar bursa, whereas there were no cases of fluid accumulation in the controls. A hypoechoic, oval subcutaneous thickening in the anterior wall of the superficial infrapatellar bursa was detected in 35 (18.4%) and 4 (2.7%) knees, respectively. Prepatellar subcutaneous thickening was detected in 45 knees (23.7%) in group 1, but in only 2 knees (1.4%) in group 2. Two knees in group 1 had thickened and inhomogeneous patellar tendons, while one in group 2 had a thickened and 2 both thickened and hypoechoic patellar tendons. We conclude that ultrasonography is a useful method for the detection of bursitis and soft tissue changes in carpet-layers. Detection of a fluid collection in a bursa does not necessarily denote bursitis of clinical importance, but does signify irritation due to work stress. Patellar tendon pathology is rare among carpet-layers and is probably unrelated to the occupation.

AbstractThe literature is scarce on the intermaxillary elastics impacts on soft tissue during the treatment of Class II malocclusion The purpose of the present study was to compare the soft tissue changes after the treatment of Class II malocclusion using intermaxillary elastics with and without the premolars extraction. The sample consisted of 41 patients Class II Division 1 malocclusion with bilateral molar relationship of at least ½ cusp, divided into two groups. Group 1: 21 patients (mean age 18.97 years) treated for a mean period of 3.15 years with intermaxillary elastics without dental extractions. Group 2: 20 patients (mean age,17.40 years) treated for a mean period of 3.07 years with intermaxillary elastics and extraction of two maxillary premolars. Lateral cephalometric radiographs were used to measure the soft tissue and incisor variations before and after orthodontic treatment. Dolphin Imaging Premium software was used for radiographic analysis. Groups 1 and 2 were highly similar concerning age, initial overjet, molar relationship, treatment time, and initial cephalometric measurements. Statistically significant differences between both groups were observed (P<0.05) related to the anteroposterior position of the lower lip in Group 2 and facial convexity angle in Group 1. Conclusions: Both treatment modalities promoted similar effects on the facial profile, except for the greater retrusion of the lower lip in the protocol with extractions and decrease in the facial convexity in the protocol without extractions.

Tooth Extractions ResumoA literatura é escassa quanto ao impacto dos elásticos intermaxilares nos tecidos moles durante o tratamento da má oclusão de classe II. O objetivo deste trabalho foi comparar as alterações tegumentares do tratamento da má oclusão de Classe II com elásticos intermaxilares sem extração e com extrações de pré-molares. A amostra retrospectiva foi de 41 indivíduos que apresentavam no início do tratamento relação molar de no mínimo 1/2 Classe II bilateral e foram divididos em dois grupos. Grupo 1: 21 pacientes (média de idade inicial de 18,97 anos), tratados por um período médio de 3,15 anos, sem extrações e com uso elásticos intermaxilares; Grupo 2: 20 pacientes (média de idade de 17,40 anos), tratados por um período médio de 3,07 anos, com extrações de dois pré-molares superiores e elásticos. As telerradiografias foram usadas para aferir as medidas tegumentares e a variação dos incisivos antes e depois do tratamento ortodôntico através do software Dolphin Imaging Premium 11.7. Ambos os grupos mostraram alto grau de compatibilidade nos quesitos idade, overjet inicial, relação molar, tempo de tratamento e medidas cefalométricas iniciais. Os resultados ao final do tratamento mostraram diferença estatisticamente significante entre os grupos (p<0,05) na posição anteroposterior do lábio inferior (Grupo 2) e no ângulo de convexidade facial (Grupo 1). Conclusões: As duas modalidades de tratamento promovem efeitos semelhantes no perfil facial, exceto pela maior retrusão do lábio inferior no protocolo com extrações e diminuição da convexidade facial no protocolo sem extrações.

The present study was undertaken to evaluate and compare the skeletal, dental, and soft tissue changes in skeletal Class II division 1 cases treated with Twin Block and Clear Block appliances using a cephalogram. A total of 40 patients of age between 12-14 years were randomly divided into two equal groups. Group 1: treated with Twin Block appliance and Group 2: treated with Clear Block appliance. The pre-treatment lateral cephalogram was taken and skeletal, dental, and soft tissue parameters were evaluated and the appliance was delivered. After 8 months, another lateral cephalogram of all the cases was taken and analyzed. The pre and post-treatment values were compared between the two groups. The pre-treatment cases were almost comparable in skeletal, dental, and soft tissue features in both groups. There was a significant change in mandibular growth by SNB angle. The retrusion and extrusion of maxillary incisors as well as a proclination and extrusion of mandibular incisors were seen in group 1 while no change was observed in group 2. Treatment with Clear Block appliances has shown significant and favorable Skeletal, Dental and Soft tissue changes which are similar to already proven by the Twin Block appliance. Clear Block provides an esthetic and less bulky option for growth modification with similar results as compared to conventional Twin Block with the additional benefit of preventing lower incisor proclination.

ABSTRACT Objective: The aim of this study was to compare the skeletal, dental, and soft tissue effects of the Mandibular Protraction Appliance (MPA) application in adolescent and adult Class II malocclusion patients. Methods: The sample comprised the pretreatment and posttreatment lateral cephalograms of 39 subjects presenting Class II malocclusion treated with the MPA and fixed appliances. Sample was divided into two groups: Group 1 comprised 23 subjects (10 male; 13 female), at a mean pretreatment age of 11.75 years, with a mean treatment time of 3.32 years; Group 2 included 16 subjects (7 male; 9 female), at a mean pretreatment age of 22.41 years, with a mean treatment time of 4.24 years. Intergroup comparison of the initial and final stages and treatment changes between the groups was performed with t tests, at p< 0.05. Results: The adults showed less significant amounts of skeletal, dentoalveolar and soft tissue changes than the adolescents. There was significantly greater palatal tipping of the maxillary incisors and retrusion of the upper lip in the adolescents. The adult group showed greater mandibular incisor proclination in the posttreatment stage. Conclusion: Adult patients treated with MPA showed less significant amounts of skeletal, dentoalveolar and soft tissue changes than adolescents.
