INTRODUCTION: The present study reported the histological events that occurred in the radicular pulp of human mature teeth in the presence of medium/deep untreated caries lesions, and those teeth with restorations or direct pulp capping, with particular emphasis on the morphology of the canal wall dentine and the odontoblast layer. METHODS: Sixty-two teeth with medium/deep caries lesions, extensive restorations or after application of a direct pulp capping procedure were obtained from 57 subjects...

OBJECTIVES: This in vivo research investigated whether pulp treatments using formocresol for 7 days would cause mutagenic changes in children's lymphocytes. MATERIALS AND METHODS: The mutagenicity was tested in lymphocyte cultures established from the peripheral blood of children living in Brazil. The samples consisted of 2000 cells from teeth undergoing formocresol pulpotomies in which the formocresol pellet was sealed in the primary tooth for 7 days. It was removed on the seventh day, the base was placed, and the tooth was restored...

In this case report, we share a conservative and simple restorative management approach for a relatively complex esthetic situation on an adult patient with an ankylosed maxillary central incisor in infra-occlusion. A 37-year-old healthy female patient presented for a consultation with a chief complaint of an unappealing smile. The intraoral exam revealed tooth #8 (FDI 11) was in obvious and significant infra-occlusion due to altered eruption. Periapical radiographs of this area were non-contributory and all teeth responded within normal limits to pulp vitality tests...

N A Taha, S Z Abdelkhader
AIM: To assess the outcome of full pulpotomy using Biodentine in permanent teeth with carious exposures and symptoms indicative of irreversible pulpitis. METHODOLOGY: Sixty-four permanent molar teeth with symptomatic vital pulps in 52 patients aged 19-69 years were included. Preoperative pulpal and periapical diagnosis was established. After informed consent, the tooth was anaesthetized, isolated using rubber dam and disinfected with 5% NaOCl before caries excavation; subsequently, the pulp was amputated to the level of the canal orifices...

AIM: Post and core procedures are important clinical methods in routine dental practice. The present research aimed to radiographically assess the quality of post seating performed by undergraduate students at the College of Dentistry, Jazan University. MATERIALS AND METHODS: A total of 343 periapical X-rays of cemented posts (170 from males and 173 from females) were assessed. The assessment covered tooth type, arch, gender, type of post, length of post in relation to the crown and root lengths, the presence of any abnormality in post space, status of the remaining gutta-percha (GP), and the presence or absence of spaces between the end of post and GP...

The purpose of this study was to test whether prosthetic treatment with different intraradicular posts influences the color of the buccal gingiva at teeth restored with zirconia crowns. A total of 31 patients in need of a full-coverage single crown at an endodontically treated premolar, canine, or incisor in the maxilla or the mandible were included. The patients were randomly assigned to receive composite build-ups using titanium (Ti), zirconia (Zi), or glass-fiber (Gf) posts or a build-up using no post at all (NP)...

Background: Crown fracture is the most common type of fracture and frequently affects the anterior teeth. Crown fractures have been treated in several ways depending on the location and kind of fracture. This case emphasizes reattachment of fractured fragments using fiber-reinforced post. Also this case report underlines the related aesthetic concerns of reattaching of the fractured fragment. Case Report: Intraorally, examination revealed a complicated crown-root fracture of the left maxillary central (#21) and lateral incisor (#22)...

PURPOSE: To determine the performance of a resin composite material specially developed for core build-ups in comparison with conventional restorative materials. METHODS: 90 roughened ceramic blocs were divided into three groups; one group (n=30) was used for the core build-up material (Gradia Core) and the other two groups (n=30, each) were used for two conventional restorative materials (Tetric EvoCeram, Compoglass F). After adhesive fixation, specimens of each material were subdivided in accordance with the storage conditions (thermocycling or water storage)...

Root resorption is the loss of hard dental tissue as a result of odontoclastic action involving vital and pulpless teeth. Cervical root resorption (CRR) is a type of external resorption which usually occurs immediately below the epithelial attachment of the tooth in the cervical region. The idiopathic cervical resorption (ICR) refers to a clinical situation in which all other causes, whether local or systemic, have been ruled out as the origin of the disease. The early stage is asymptomatic and might be diagnosed by a routine radiograph or a clinical examination...

PURPOSE: This clinical retrospective study evaluated the survival and risk factors associated with failures of resin-based composite restorations in primary teeth. METHODS: A total of 212 restorations in primary teeth from records of 76 high caries-risk children were included. The restorations' longevity for up to six years of follow-up was assessed using the Kaplan-Meier survival test. Multivariate Cox regression analysis with shared frailty was used to evaluate the factors associated with failures (P<0...

INTRODUCTION: Pulpotomy is the most common treatment to preserve vitality of cariously exposed molars. Various pulpotomy medicaments used should be antimicrobial, should help in healing without damaging surrounding tissue, and should not affect eruption of permanent teeth. Thus, this study was conducted to evaluate and compare the clinical and radiographic outcomes of formocresol (FC) and sodium hypochlorite (NaOCl) in primary molars. The aim of this randomized study was to compare the clinical and radiographic success rate of FC and 5% NaOCl as a pulpotomy medicament in primary molars...

PURPOSE: To evaluate the clinical efficacy of incomplete caries removal in permanent molars with deep dental caries. METHODS: One hundred and two permanent molars with deep dental caries were treated with partial caries removal combined with tight resin restoration. The patients were followed up for more than 6 months, the pulp retention rate and subjective feelings were evaluated.

Introduction: Early detection of secondary proximal caries is critical for the preservation of tooth vitality. This study sought to assess and compare the diagnostic accuracy of DIAGNOdent and digital radiography for detection of secondary proximal caries adjacent to composite restorations. Methods: Sixty extracted molars including 30 teeth with carious lesions and 30 sound teeth were randomly selected. Class II cavities were prepared in all teeth and carious dentin was intentionally left in the gingival floor of cavities in 30 carious teeth...

PURPOSE: The purpose of this study was to evaluate the clinical and radiographic outcomes of a bioactive tricalcium silicate [Ca3SiO5]-based dentin substitute and a light-activated calcium hydroxide [Ca(OH)2]-based liner as indirect pulp treatment (IPT) interventions for vital primary molars with carious lesions approaching the pulp. METHODS: Eighty children, aged four to eight years old, with 160 bilateral primary teeth without signs or symptoms of irreversibly inflamed or degenerative pulp tissue were treated in a split-mouth design trial comparing IPT using Ca3SiO5 or Ca(OH)2...

The optimal way of restoring a non vital tooth with dowel-core technique has long been a controversial matter. The purpose of this review was to assess the factors that may influence the successful restoration of root filled teeth with root canal dowels. The first part of the review discusses indications and physical parameters of dowel. Searches were performed in PubMed/Medline database using single or combined key words to obtain the most relevant list of references. Articles selected in the search process were obtained from the journals and reviewed with every aspect of dowel system for reconstruction of endodontically treated teeth...

Use of direct composite and indirect laminate veneers has been an alternative to metal- and all-ceramic crowns for anterior teeth restorations. Dental traumas are the most common reasons for excessive tissue loss. Treatment options depend on the amount of remaining tissue, the extent of the damage to dental pulp and periapical tissues and the time elapsed before dental treatment. The aim of this case report was to evaluate the direct and indirect techniques used in the treatments of traumatically fractured anterior teeth...
