Filter by:Removal of infected dentin contaminated with bacteria and remaining affected dentin detected as firm is the conventional strategy for the management of cavitated caries lesions. Recently, this strategy is termed as selective removal to firm dentin (SRFD) and seems to increase the potential risk of pulp exposure or loss of pulp vitality for deep caries lesions radiographically extending ¾ of dentin tissue. Alternatively, selective removal to soft dentine (SRSD) that refers to removal of caries tissue at the periphery of the cavity to firm dentin and remaining caries tissue detected as soft or leathery in proximity with the pulp might be a less invasive excavation method for deep caries lesions to maintain pulpal health. However, information on clinical advantages or disadvantages of SRSD and SRFD excavation methods is sparse and mostly rely on studies conducted for primary teeth. Moreover, clinical trials are needed to demonstrate the combined effect of carious removal strategies and calcium silicate-based materials. The aim of this study is comparison of clinical success rates of SRSD and SRFD techniques in posterior deep caries lesions. The primary outcome of the study is comparison of clinical success of SRSD and SRFD techniques by clinical and radiographic examination after 3 months, 6 months, 1 year and 2 years. The secondary outcome of the study is to investigate whether or not calcium silicate-based materials have an effect on the success rate of the treatment.
The management of deep carious lesions approaching a healthy pulp is considered a challenge to the dental practitioner. The conventional treatment of deep carious lesions requires the removal of all infected and affected dentin to avoid more cariogenic activity.
The purpose of this split-mouth study was to compare the efficacy of using Bio-active cement versus Packable glass ionomer for cementation of posterior zirconia pediatric crowns.
Preservation of the remaining vital portion of curiously exposed pulpal tissue in primary teeth, was one of the most frequent problems in pediatric dentistry. To solve this problem, pulpotomy therapy was introduced. Pulpotomy involves amputation of the coronal portion of affected or infected dental pulp, treatment of the remaining vital radicular pulp tissue surface should preserve the vitality and function of all or part of the remaining radicular portion of the pulp. Furthermore, it is an accepted procedure for treating both primary and permanent teeth with carious pulp exposures, several materials have been using for capping the radicular pulp after pulpotomy, these included formocresol, glutaraldehyde, ferric sulfate, and mineral trioxide aggregate. Allium sativum is one of the most extensively researched medical plants and its antibacterial activity depends on allicin produced by the enzymatic activity of allinase (a cysteine sulfoxide lyase). Allicin and other thiosulfinates are believed to be responsible for the range of therapeutic effects reported for garlic. Garlic extract has been reported to inhibit growth of various gram‑positive and gram‑negative bacteria. Previous studies showed that A. sativum oil is used as new pulp medications and it offers a good healing potential, leaving the remaining pulp tissue healthy and functioning. MTA is a unique material with various advantages. It has been used successfully by pediatric dentists in a variety of clinical applications. However, its drawbacks especially its high cost, discoloration potential, difficulty in handling, and long setting time.
Based on the changing understanding of carious biofilm development and caries progression, Sealing carious dentine beneath a restoration deprives the caries biofilm of nutrients and alters the environment sufficiently to slow or arrest lesion progression. This has the added benefit of avoiding pulp exposure and subsequent treatment .The evidence base supporting the biological approaches which include Hall technique has been steadily increasing in the last few years. This has given rise to a growing trend towards a biological approach by Paediatric dentists and has led to an increasing concern about the merits of conventional approach in treatment of carious primary molars .
Purpose: The purpose of this study was to investigate the clinical and microbiological effectiveness of the ozone application in stepwise excavation of primary molars. Methods: This study was conducted in vivo conditions with 105 lower primary second molars that had deep caries lesions with the risk of pulpal exposure. The teeth were randomly divided into three groups: Conventional stepwise excavation without any disinfectant, 2% chlorhexidine digluconate(CHX) and ozone application. In four different stages (after; initial excavation, ozone/CHX application, four months, final excavation), dentine samples were collected for microbiological analysis of mutans streptococci, lactobacilli and total number of colony forming units. Clinical changes as dentine colour, humidity, consistency were recorded. The data were analysed by Mann-Whitney U, Friedman and chi-square test.
This study aimed to assess the clinical and radiographic success for photo-activated oral disinfection (PAD) and calcium hydroxide in indirect pulp treatment (IPT) of young permanent molars.
This study is comparing between the Silver Diamine Fluoride after minimal caries removal versus glass ionomer in permanent teeth with open apex
Untreated dental caries is a worldwide pandemic (Edelstein, 2006). Due to limited financial resources, poor access to basic oral care, and the high cost of restorative treatment, children of low-income nations have their general health, social well-being, and education opportunities affected by untreated dental caries (Baelum et al., 2007). Traditional treatment of cavitated dentin lesions advocates complete removal of the decayed structure, i.e. the infected and affected dentin layers. During this procedure, however, a significant quantity of the dental structure is removed, and the pulp tissue may be exposed. In light of this, the complete removal of all decayed structures from a tooth with cavitated lesions is no longer seen as mandatory, as this increases the chance of pulp exposure, post-operative pain and weakens the tooth structure, and there is growing evidence to support incomplete removal of decayed tissue prior to the restoration of the cavity. It is argued, however, that carious lesions remaining in the cavity must be completely sealed in order to prevent their progression (Yee et al., 2009). Arresting Caries Treatment (ACT) has been proposed to oversee untreated dental caries in children of disadvantaged communities. Treatment of carious lesions based on minimally invasive technique methods aim to prevent their progression and preserve pulp vitality by means of standards of anticipation, remineralization and minimal intervention in the dental tissue (Bedi and Sardo-Infirri, 1999).
This study aimed to evaluate the clinical performance of White MTA (MTA, Angelus, Londrina, Brazil) and Biodentine™ in pulp capping of cariously exposed mature permanent teeth. The investigator performed a prospective longitudinal randomized controlled study utilizing vital permanent mature teeth with deep caries. Patients will be divided randomly into Biodentine™ and MTA groups; Teeth will be assessed clinically and radiographically prior to the procedure. Caries will be excavated under local anesthesia, hemostasis is achieved after pulp exposure using NaOCl and will be capped with Biodentine™ or MTA. Clinical and radiographical follow-up will be performed by a blinded calibrated evaluator after six months and one year, and yearly after.
