Assessment of the Oral Health Impact Profile (OHIP-14) improvement of different treatments for dentin hypersensitivity in noncarious cervical lesions-a randomized clinical study.

OBJECTIVES: To assess the improvement on oral health-related quality of life (OHRQoL) of individuals with cervical dentin hypersensitivity (CDH) with the noncarious cervical lesion (NCCLs) subjected to different treatments. MATERIAL AND METHODS: A single-blind randomized clinical trial was conducted with patients (n = 74) randomly allocated into three groups according to the treatment performed: PO, potassium oxalate (Oxa-Gel BF); LL, low-power laser irradiation; and POLL, potassium oxalate (Oxa-Gel BF) associated with low-power laser irradiation. The treatments were applied in four steps, weekly. The questionnaire Oral Health Impact Profile (OHIP-14) was applied before initiating and immediately after the fourth session. The greater the sum of the score, the smaller the measurement of OHRQoL. RESULTS: The total mean values of the variables at the final moment were significantly lower than the initial one for all dimensions (p value ranging from < 0.001 to 0.006). Furthermore, the OHIP-14 scores final analysis between the groups indicated that the POLL group compared to LL had a significantly lower final score for the functional limitation (p = 0.009), physical pain (p = 0.049), and psychological discomfort (p = 0.035) dimensions and that group PO compared to group LL had a significantly lower final score for the functional limitation dimension (p = 0.024). CONCLUSIONS: There was a reduction in the OHIP-14 score for all dimensions, indicating an improvement in patients' quality of life after the use of desensitizing therapies. Patients in group LL had a higher functional limitation, physical pain, and psychological discomfort. CLINICAL RELEVANCE: This study indicated improvement of desensitizing therapies for CDH to improve patients' OHRQoL. TRIAL REGISTRATION: This trial was registered in the Brazilian Clinical Trials Registry Platform (REBEC protocol number RBR-4ybjmt).

Matriz palatina individual para estratificação de restauração Classe IV / Individual palatine matrix for Class IV restoration stratification

Existem diversas opções restauradoras para dentes anteriores envolvendo a superfície próximo-incisal, com lesões de cárie ou fraturas coronárias. Sempre que possível, a colagem do fragmento autógeno deve ser preferida por aliar conservação de estrutura com excelentes resultados funcionais e estéticos. Quando o fragmento não se apresenta adequado, existente ou conservado, o uso de resinas compostas diretas é a melhor indicação para grande maioria dos pacientes, que são crianças e jovens, nos quais a cerâmica não pode ainda ser indicada. As resinas compostas permitem a máxima conservação dos tecidos dentários, oferecem estética satisfatória, porém, exigem muita atenção para detalhes, correto diagnóstico e planejamento, bem como a aplicação de um protocolo composto de passos organizados que permite que o clínico obtenha resultados estéticos satisfatórios. O presente trabalho relata, através de um caso clínico, o protocolo da confecção e utilização da matriz palatina individual, a partir do enceramento diagnóstico, para auxiliar a estratificação da restauração direta com resina composta.

There are different options of treatment in anterior teeth for dental practitioners, involving proximal-incisal surfaces, teeth with decay, or crown fracture. If possible, the use of autogenous fragment is chosen because it is a conservative approach aligned with functional and aesthetic excellent results. In cases that the fragment does not appear appropriate, it is not found, or it is not preserved the use of direct composite resin is the best indication for most of the patients, who are children and young people. Once in these patients ceramics cannot be indicated yet. Composite resins provide maximum dental structure conservation, and satisfactory aesthetics, however, it requires high level of attention for the details, accurate diagnosis and planning, as well as the application of a protocol with organized steps which allow the clinician to obtain satisfactory aesthetic results . The present paper reports through a clinical case, the protocol of confection and use of the individual palatine matrix, from the diagnostic waxing, to assist the stratification of the direct restoration with composite resin.
