Resumo Introdução A associação entre o tratamento da deficiência maxilar transversa e a recuperação das funções auditivas e vocais ganhou atenção nos últimos anos. Objetivo Avaliar os efeitos da expansão rápida da maxila na função auditiva e vocal em crianças sem fissura labiopalatina e com fissura labiopalatina bilateral com deficiência maxilar transversa. Método Foram recrutados para este estudo 53 pacientes (26 sem fissura e 27 com fissura labiopalatina bilateral; média de 11,1 ± 1,8 anos) que necessitam de expansão rápida da maxila para correção de arcos maxilares estreitos. Oito subgrupos foram estabelecidos com base no grau de perda auditiva. Registros audiométricos e timpanométricos de tons puros foram obtidos para cada indivíduo em quatro períodos. Os primeiros registros foram obtidos antes da expansão rápida da maxila (T0), o segundo após a expansão (T1) (média de 0,8 meses), o terceiro após três meses (T2) (média de 3 meses) e o quarto no fim do período de retenção (T3) (média de 6 meses). Anova e o teste post-hoc de Tukey HSD foram usados para análise dos dados. Além disso, a análise da voz foi feita com um programa PRAAT atualizado em um laboratório de fala computadorizadaem T0 e T2. Foi usado um teste t de amostras pareadas para comparação dos valores médios dos parâmetros de voz em T0 e T2 nos dois grupos. Resultados O tratamento com expansão rápida da maxila produziu um aumento significativo nos níveis auditivos e nos volumes da orelha média de todos os pacientes sem fissura e pacientes com fissura labiopalatina bilateral e níveis auditivos normais e com perda auditiva condutiva leve, durante os períodos de observação T0-T1, T1-T2, T0-T2 e T0-T3 (p < 0,05). Aumento significativo foi observado nos volumes da orelha média direita durante os períodos T0-T1, T0-T2 e T0-T3 em pacientes sem fissura e com perda auditiva moderada. Para a análise de voz, diferenças significantes foram observadas apenas entre a frequência fundamental média T0 e T2 (F0) e a porcentagem de jitter (p < 0,05) no grupo sem fissura. No grupo com fissura, não foram observadas diferenças significantes para nenhum parâmetro de voz entre os períodos T0 e T2. Conclusão A correção da anatomia palatal pela expansão rápida da maxila tem um efeito benéfico tanto na melhoria da audição quanto na função normal da orelha média em pacientes sem fissura e com fissura labiopalatina bilateral. Da mesma forma, a expansão rápida da maxila influencia significativamente a qualidade da voz em pacientes sem fissura, sem efeito significativo em pacientes com fissura labiopalatina bilateral.

Abstract Introduction The association between the treatment of transverse maxillary deficiency and the recovery of hearing and voice functions has gained attention in recent years. Objective This prospective controlled trial aimed to evaluate the effects of rapid maxillary expansion on hearing and voice function in children with non-cleft lip palate and bilateral cleft lip palate with transverse maxillary deficiency Methods 53 patients (26 non-cleft and 27 bilateral cleft lip palate; mean age, 11.1 ± 1.8 years) requiring rapid maxillary expansion for correction of narrow maxillary arches were recruited for this trial. Eight sub-groups were established based on the degree of hearing loss. Pure-tone audiometric and tympanometric records were taken for each subject at four different time periods. The first records were taken before rapid maxillary expansion (T0), the second after expansion (T1) (mean, 0.8 months), the third after three months (T2) (mean, 3 months) and the fourth at the end of retention period (T3) (mean, 6 months). ANOVA and Tukey HSD post-hoc tests were used for data analysis. Additionally, voice analysis was done using an updated PRAAT software program in a computerized speech lab at T0 and T2. A paired-samplet-test was used for comparisons of mean values of T0 and T2 voice parameters within both groups. Results Rapid maxillary expansion treatment produced a significant increase in the hearing levels and middle ear volumes of all non-cleft and bilateral cleft lip palate patients with normal hearing levels and with mild conductive hearing loss, during the T0-T1, T1-T2, T0-T2, and T0-T3 observation periods (p < 0.05). The significant increase was observed in right middle ear volumes during the T0-T1, T0-T2 and T0-T3 periods in non-cleft patients with moderate hearing loss. For voice analysis, significant differences were observed only between the T0 and T2 mean fundamental frequency (F0) and jitter percentage (p < 0.05) in the non-cleft group. In the cleft group, no significant differences were observed for any voice parameter between the T0 and T2 periods. Conclusion Correction of the palatal anatomy by rapid maxillary expansion therapy has a beneficial effect on both improvements in hearing and normal function of the middle ear in both non-cleft and bilateral cleft lip palate patients. Similarly, rapid maxillary expansion significantly influences voice quality in non-cleft patients, with no significant effect in BCLP patients.

Abstract Objective: To compare the fluoride release from Conventional Glass Ionomer Cement (GIC), Resin Modified GIC (RMGIC), and Cention N Alkasite Material. Material and Methods: Forty- five disc-shaped specimens of three different restorative materials (Conventional GIC, RMGIC, and Alkasite material) were made and divided into 3 groups (n=15). Fluoride release was evaluated at the end of Day 1, 7, 14, and Day 28 using fluoride ion-selective electrode. Intergroup and Intra-group analysis was done using One-way ANOVA with a Post-hoc test. A p-value of <0.05 was considered statistically significant. Results: Cention showed more fluoride release (in parts per million) than GIC and RMGIC at increased time duration. However, at the end of day 1, there was lesser fluoride release with Cention, as compared with the other groups. Conclusion: The new Alkasite restorative material showed promising results in terms of fluoride release and is better than GIC and RMGIC at increased time duration.

RESUMO Introdução: as dilacerações dentárias são anomalias caracterizadas por desvio acentuado no eixo longitudinal de um dente. Elas podem ocorrer na coroa, entre a coroa e a raiz, ou na raiz. Apesar de não serem muito comuns, os incisivos superiores impactados apresentando dilaceração radicular representam um desafio para o clínico, quanto ao diagnóstico e tratamento. Descrição: o presente relato de caso descreve o tratamento de um incisivo central superior impactado horizontalmente e com dilaceração, em uma menina com 12 anos de idade. Tomografias computadorizadas de feixe cônico foram utilizadas para localizar com precisão a posição do dente dilacerado e avaliar o grau de formação e de dilaceração da raiz. O tratamento incluiu exposição cirúrgica e tração ortodôntica, seguida de tratamento do canal radicular e apicectomia. Resultados: por meio de uma abordagem interdisciplinar meticulosamente planejada, o incisivo central impactado com dilaceração foi devidamente alinhado e demonstrou boa estabilidade em acompanhamento de longo prazo. Conclusão: levando-se em consideração as preocupações e expectativas da paciente, a comunicação interativa adotada entre o cirurgião oral, ortodontista e o endodontista ajudou na obtenção de resultados estéticos, estruturais e funcionais satisfatórios no presente caso.

ABSTRACT Introduction: Tooth dilacerations are dental anomalies characterized by an abrupt deviation in the longitudinal axis of a tooth. They may occur either in the crown, between the crown and root, or in the root. Although not so common, impacted maxillary incisors exhibiting root dilaceration pose a diagnostic and treatment challenge to the clinician. Description: This case report describes the management of a horizontally impacted and dilacerated maxillary central incisor in a 12-year-old girl. Cone-beam computed tomographic scans were used to accurately localize the position of the dilacerated tooth, and to assess the extent of root formation and degree of dilaceration present in the root. Treatment included surgical exposure and orthodontic traction, followed by root canal treatment and apicoectomy. Results: Through a meticulously planned interdisciplinary approach, the impacted dilacerated central incisor was properly aligned and demonstrated good stability after the long-term follow-up. Conclusion: Taking into consideration the concerns and expectations of the patient, communicative feedback between the oral surgeon, orthodontist and endodontist helped achieving successful esthetic, structural and functional outcome in the present case.

ABSTRACT Background: The understanding of the pathomechanics of shoulder impingement has evolved over the years. Likewise, assessment techniques and effective treatment strategies have also been developed. Physical therapists should keep up-to-date on the current evidence. Objective: This study explored the practices currently used by Indian physical therapists for the assessment and management of shoulder impingement syndrome (SIS). Method: Using an online questionnaire, therapists were asked to declare the causes, methods of assessment and their choices of physical therapy techniques for the management of SIS. The proportions of therapists using different techniques were analyzed descriptively, and comparisons across gender, experience level, and training were made. Data were analyzed to see if the choices of respondents compared with their responses for etiology. Results: A total of 211 responses were analyzed. Most respondents (>75%) believed that overuse and abnormal motion/posture are the most significant causes of SIS. However, fewer respondents reported assessing posture (60.2%) and dyskinesis, especially in women (24.2%). Ninety-four percent of the respondents reported using exercises, but exercise prescription was rather generic. Therapists additionally trained in the techniques of joint mobilization or taping declared using these techniques more frequently. The use of interferential therapy and ultrasound was reported by 89.5% and 98.4% of respondents, respectively Conclusion: Most therapists declared awareness of current recommended practices, but patient assessment, exercise prescription, and use of electrotherapy modalities were only partially based on current evidence. The study helps to identify gaps in current physical therapy approaches to SIS in India.
