Iodoform Vs Calcium Hydroxide/Zinc Oxide based pastes: 12-month findings of a Randomized Controlled Trial.

This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused by dental caries or trauma, in 23 children (2-7 years old). A single trained operator performed the CT in a single visit in cases without periapical or interradicular radiolucency (PIR) or in multiple visits in cases with PIR. Participants were selected based on specific inclusion and exclusion criteria, and randomly allocated into two groups: Group 1 (G1) - iodoform paste (iodoform + camphorated parachlorophenol + ointment comprising prednisolone acetate 5.0 mg and rifamycin 1.5 mg); Group 2 (G2) - Calen®/ZO paste. Treated teeth were restored with composite resin immediately after the root canal filling. The outcomes were evaluated clinically and radiographically according to specific criteria. Two blinded and standardized evaluators assessed the radiographic outcomes. We used descriptive analyses due to the small sample size. CTs were performed due to caries lesions in 70.4% of the cases and due to trauma in 29.6%. Only one tooth of G1 was unsuccessful; hence, pulpectomy performance in both groups was not influenced by the filling material, nor by any other analyzed variable. The level of the root canal filling was better in the Calen®/ZO group. The clinical and radiographic twelve-month outcomes indicated successful treatment, independently of the root filling material used.

Does Smear Layer Removal Influence Root Canal Therapy Outcome? A Systematic Review.

OBJECTIVE: The aim of this systematic review was to determine whether the smear layer (SL) removal procedure influences the outcome of root canal treatment. STUDY DESIGN: We performed a search on Pubmed, Scopus, ISI Web of Science, Cochrane Library, Lilacs and SIGLE. We included randomized controlled clinical trials (RCT), with clinical and radiographic outcomes, conducted on subjects who had undergone root canal therapy. The protocol differed only in the SL removal or maintenance procedure. We evaluated the papers for risk of bias according to the Cochrane assessment tool. RESULTS: A total of 1,983 articles were found, after removal of duplicates, 892 remained. We included two studies in this review. One study revealed a low risk of bias and a high success rate for the SL removal group compared to the non SL removal group (P = 0.04), while the other study had a high risk of bias and found no difference between the SL removal and non SL removal groups (P = 1.00). CONCLUSION: We concluded that the SL removal for root canal treatment of primary teeth with initial clinical signs and symptoms or pulpal necrotic status, could benefit the outcome, although further RCT should be performed to achieve evidence.

The influence of smear layer removal on primary tooth pulpectomy outcome: a 24-month, double-blind, randomized, and controlled clinical trial evaluation.

BACKGROUND: The effect of smear layer (SL) removal on primary tooth pulpectomy outcome has not been well elucidated. AIM: To determine the effect of SL removal on primary tooth pulpectomy outcome. METHODS: This is a double-blind, randomized, and controlled clinical trial. Forty-eight patients were randomly divided into SL removal (G1 = 40 teeth) or smear layer nonremoval (G2 = 42 teeth) groups. Following the chemomechanical preparation with K-files and 2.5% sodium hypochlorite (NaOCl), teeth were irrigated with either 6% citric acid and 0.9% physiologic solution (G1) or only 0.9% physiologic solution (G2). Camphorated paramonochlorophenol was used as intracanal medication. At the second appointment, 1 week after, root canals were filled with zinc oxide-eugenol paste. Clinical and radiographical baseline criteria were stipulated equally for both groups. RESULTS: The success rate (G1 = 91.2%; G2 = 70.0%) was statistically different (P = 0.04) between the groups. In G2, the outcome was affected significantly by pulpal necrosis (P = 0.02), pre-operatory symptoms (P = 0.02), and periapical/inter-radicular radiolucency (P = 0.04). CONCLUSION: The pulpectomy outcome was improved by smear layer removal. The outcome for teeth with pulpal necrosis, pre-operatory symptoms, or periapical/inter-radicular radiolucency was significantly improved by removal of the smear layer.

Long-term outcomes of primary tooth pulpectomy with and without smear layer removal: a randomized split-mouth clinical trial.

PURPOSE: The aim of this study was to evaluate, via clinical and radiographic assessment, pulpectomy outcomes performed on primary anterior teeth both with and without a citric acid solution to enhance smear layer removal. METHODS: Patients with a matched pair of primary incisors (split-mouth design) with irreversible pulp changes were selected. A total of 36 teeth (18 children) received pulpectomies and were followed for 36 months. Pulpectomies were performed using sodium hypochlorite and saline solution as canal irrigants; during the last irrigation, the tooth was randomly selected to receive ( Group 1) or not receive (Group 2) the citric acid solution for smear layer removal. The roots were filled with ZOE paste. RESULTS: Overall pulpectomy success was 90.6%. Cases with smear layer removal were successful 82.3% of the time; those without smear layer removal, 88.2%, and there were no statistical differences (P=1.00). CONCLUSION: Pulpectomy with smear layer removal in primary incisors exhibited, after 36 months, a high success rate; however, comparable results were obtained when the smear layer was not removed.

Laser de baixa potência no tratamento da síndrome da ardência bucal: relato de caso clínico / Low-level laser in the treatment of the burning mouth syndrome: a clinical report

A Síndrome da Ardência Bucal é uma afecção intra-oral dolorosa complexa caracterizada pela sensação de queimação da mucosa bucal. Este trabalho objetiva apresentar o relato de uma paciente, sexo feminino, 87 anos de idade, leucoderma que compareceu ao o serviço de Estomatologia de Universidade pública de ensino superior em Odontologia do Rio de Janeiro - RJ com a queixa de queimação em língua há um ano sem nenhum fator iniciador, porém com aumento da intensidade ao consumir alimentos ácidos e ao longo do dia. Na anamnese referiu não apresentar desordens metabólicas ou fazer uso de medicamentos e no exame físico não foram observadas alterações orais que justificassem o quadro de ardência. A hipótese diagnóstica foi de síndrome da ardência bucal, confirmada através da ausência de achados clínicos e de alterações nos exames sorológicos solicitados. A conduta consistiu em aplicações de laser de baixa potência de forma pontual e em varredura na língua durante dois meses (15 sessões), período em houve estabilização do quadro, e remissão significativa do sintoma (escala visual analógica inicial = 8 e final = 2). Desta forma, o laserterapia mostrou-se uma alternativa terapêutica eficaz no tratamento deste caso de Síndrome da Ardência Bucal e ressalta-se a importância da exclusão de outras morbidades antes de concluir o diagnóstico desta entidade.

The Burning Mouth Syndrome is complex and painful intra-oral affection characterised by burning sensation of oral mucosa. This study is aimed at reporting a case of a 87-year-old Caucasian female patient who attended the stomatology service, at a public university in Rio de Janeiro, complaining that her tongue was "burning" for more than one year despite the absence of a cause, although such a sensation worsened during consumption of acid food as well as over the day. In the anamnesis, she reported no metabolic disorders or use of medications, and no oral alteration explaining such burning symptoms was observed on clinical examination. The diagnostic hypothesis was burning mouth syndrome, which was confirmed because of the absence of both clinical findings and serological changes in the exams. The procedure consisted of applying low-level laser on the tongue in punctual and scanning modes during two months (15 sessions), period in which the clinical picture become stable and significant remission of the symptom was observed (initial and final analogical visual scales = 8 and 2, respectively). In this way, laser therapy was shown to be an efficient therapeutic alternative in the treatment of the present case of Burning Mouth Syndrome, thus emphasising the importance of ruling out other morbidities prior to considering the diagnosis of this condition.
