Acutely infected teeth: to extract or not to extract?

Abstract: Not only laymen but also dentists generally believe that extraction of acutely infected teeth should be avoided until the infection subdues by using systemic antibiotics. The aim of this study was to compare perioperative complications in routine extractions of acutely infected teeth with extractions of asymptomatic teeth. This prospective study was performed with 82 patients. Severe pain on percussion of the relevant tooth was considered as basic criteria for acute infection. The acutely infected teeth were labeled as the study group (n = 35) and the asymptomatic teeth as the control group (n = 47). The extractions were done using standard procedures. The amount of anesthetic solution used and duration of extractions were recorded. Postoperative severe pain and exposed bone with no granulation tissue in the extraction socket were indications of alveolar osteitis (AO). The level of statistical significance was accepted as 0.05. Symptoms that could indicate systemic response, including fever, fatigue, and shivering were not found. There was no statistically significant difference between groups in terms of AO, amount of anesthetic solution used, and duration of extraction. The presence of an acute infection characterized by severe percussion pain is not a contraindication for tooth extraction. Infected teeth should be extracted as soon as possible and the procedure should not be postponed by giving antibiotics.

Newly forming bone graft: a novel surgical approach to the treatment of denuded roots

Many techniques have been proposed for root coverage. However, none of them presents predictable results in deep and wide recessions. OBJECTIVES: The aim of this case series report is to describe an alternative technique for root coverage at sites showing deep recessions and attachment loss >4 mm at buccal sites. MATERIAL AND METHODS: Four patients presenting deep recession defects at buccal sites (>4 mm) were treated by the newly forming bone graft technique, which consists in the creation of an alveolar socket at edentulous ridge and transferring of granulation tissue present in this socket to the recession defect after 21 days. Clinical periodontal parameters, including recession depth (RD), probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), plaque index (PI) and keratinized gingiva width (KGW) were evaluated by a single examiner immediately before surgery and at 1, 3, 6 and 9 months postoperatively. RESULTS: All cases showed reduction in RD and PD, along with CAL gain, although no increase in KGW could be observed. These findings suggest that the technique could favor periodontal regeneration along with root coverage, especially in areas showing deep recessions and attachment loss.

Functional and aesthetic management of worn dentition with direct composite restorations: a clinical report

The management of tooth surface loss [TSL] could be challenging in primary dental care settings. However the introduction of resin-based composite restorative materials have significantly changed our traditional mechanistic approach in favour of more tooth-tissues conservative treatments whilst improving both functional and aesthetic demands by patients. Direct banding to remaining toot tissues is more predictable than any time before, it has been clinically proven that the applications of direct composite restorations could be extended beyond building up a single tooth and become a viable option for full mouth rehabilitation. Economic factors are crucial elements in the success of our day to day dental treatments as there is more emphasis on implementing time and cost-effective and reversible treatments at low biological risks

The importance of apical patency and cleaning of the apical foramen on root canal preparation

O limite apical de trabalho sempre constituiu um tema de muita controvérsia. Apesar dos vários trabalhos que já foram publicados sobre o assunto, ainda não existe uma definição sobre ele. A recente discussão sobre patência apical e limpeza do forame e a incorporação desses procedimentos ao tratamento endodôntico parece ter gerado uma polêmica maior ainda. É possível que essa polêmica tenha a sua causa maior na ausência de interrelação do conhecimento que se tem sobre o coto pulpar e tecidos periapicais e a realidade dos fatos da clínica. Através de uma discussão sobre os principais aspectos desse tema, este artigo pretende apresentar uma nova concepção a respeito da importância da patência apical e limpeza do forame no preparo do canal.
