Filter by:This study aims to determine the effectiveness of an intraoral scanner with near-infrared imaging (NIRI) for the diagnosis of proximal caries.
Objective: To assess and compare the 2940 nm erbium:yttrium-aluminum-garnet (Er:YAG) laser versus a conventional rotary treatment during cavity preparation in children with regard to anxiety level, pain perception, restoration integrity, and bond interface quality. Materials and Methods: In a randomized, blinded trial using a split-mouth design, forty (9-12-year-old) children with 80 carious deciduous molars were included. The cavity in one quadrant was treated conventionally using a bur, while the cavity in the other quadrant was prepared using an Er:YAG laser. Venham's dental anxiety scale and pulse rate measurement using a fingertip pulse oximeter were used to evaluate dental anxiety levels. The Wong-Baker facial pain rating scale and the number of local anesthesia required during both interventions were further applied to investigate pain perception. At the 1-year follow-up, clinical examinations was conducted and the integrity of the restorations was clinically assessed according to the Ryge criteria. Lastly, the restored teeth were extracted and histologically evaluated for bond interface quality using scanning electronic microscopy.
Alterations in oral health of children interfere with their quality of life. Dental caries is the most common public health problem of children . The disease is the result of a complex interaction between acid producing tooth-adherent bacteria and fermentable carbohydrates. Over time, the acids in the dental plaque demineralize enamel and dentin in the fissures and the smooth surfaces of the tooth. The earliest visual sign of dental caries is white spot lesion. If demineralization continues, the surfaces of the white spot will cavitate, resulting in a cavity. If demineralization environment is reduced or eliminated, white spot lesions may remineralize and not progress. Risk factors include high numbers of cariogenic bacteria, high frequency sugar consumption, inadequate salivary flow, insufficient fluoride exposure, poor oral hygiene, and poverty. The early diagnosis and management of caries still a challenge of dental care for children . The prefabricated metal crowns are often the first choice for the repair of severely damaged primary teeth and have been one of the most effective and efficient methods of tooth restoration in pediatric dentistry since Humphrey first used them in pediatric patients in 1950 . They are used to restore primary or permanent teeth with extensive or multisurface cavities, cervical decalcification, and/or developmental defects . The prefabricated metal crowns have many advantages over other crown types and dental restorative materials . Their life span is the same as that of an intact primary tooth, they provide protection to the residual tooth structure that may have been weakened after excessive caries removal, the technique sensitivity or the risk of making errors during their application is low and their cost is low . Despite many advantages, the metal appearance of these crowns is unpleasant to the parents and children and they prefer tooth-colored restorations to silver-colored fillings regardless of location of restorations . Inflammation of the surrounding gingival tissue is a problem frequently associated with prefabricated metal crowns. The incidence of gingivitis has been reported to be higher around poorly fitting crowns than around the crowns considered to be well adapted . Considering the increasing demand for esthetic restorations, several treatment options have been proposed for primary teeth to overcome this problem such as strip crowns, pre-veneered stainless steel crowns and zirconia crowns . Strip crown was introduced by Webber et al., in 1979 . strip crowns are available in different brands but the most commonly used resin composite strip crowns worldwide is 3M ESPE crown (3M ESPE Dental). Composite resin strip crowns (SC) have been utilized for over 2 decades to restore carious primary teeth . In spite of a long time of using, there is a paucity of literature concerning the clinical success of these crowns . Incorporation of ceramic nanofibers in dental composites can significantly improve their mechanical properties and fracture toughness and thus may extend their service life. This study aimed to assess clinically and radiographicaly of primary teeth restored with stability of the glassionomer and two composite material crown restoration using the preformed strip crown technique in primary molars.
To evaluate the change of S. mutans and Lactobacillus spp. counts after all dental treatments were completed under general anesthesia and compare the groups in case of using probiotics and not using probiotics with the time for 6-months follow-up period.
the aim of the clinical trial is to evaluate the antimicrobial efficacy of the herbal mouth rinses against chlorhexidine mouth rinse.
he study was designed as a double-blind three-parallel-group randomized controlled trial, in which the evaluators and a researcher, not involved in the evaluation process, was responsible for the randomization process, were masked to the group assignment. The study will be carried out at 2 schools of the Metropolitan Area of Buenos Aires where school programs are developed by the Department of Preventive and Community Dentistry of the University of Buenos Aires, and that present homogeneous characteristics in terms of social risk. The children (n=244) attending those primary schools will be the population object of the trial. Clinical examinations Each child will go under a clinical examination to determine dental status according to the ICDAS II criteria (Pitts, 2005) and the Caries Treatment Need Index (CTNI). Intervention Children will be divided into three different groups according to the mode of treatment: - NaF varnish group (NaFV) Professional application of 5% NaF varnish twice a year pH 7 (ClinPro White Varnish®) according to manufacturer's instructions. - APF in tray Group (APFt) Professional application of APF 1.23% twice a year pH 3.5 (Klepp®) with tray according to manufacturer's instructions - APF in toothbrush group (APFtbru) Professional application of APF 1.23% twice a year pH 3.5 (Klepp®) with toothbrush 2 minutes brushing according to manufacturer's instructions. Dental examination and Monitoring Observations and clinical examinations will be conducted at schools. After 12 and 24 months, the clinical examination will be repeated to assess the dental status of schoolchildren following the same criteria described. The presence of new caries lesions will be taken as a dependent variable. So sound surfaces on baseline will be observed for 24 months.
Molar incisor hypomineralization (MIH) can lead to many clinical conditions and affect oral health-related quality of life (OHRQoL).
This study aims to investigate consecutive biological changes in proximal contact tightness using digital force gauge and evaluate proximal contact location using cone beam computed tomography between class II direct composite restorations and adjacent teeth after using sectional matrix system and with different contact forming instruments.
Type of study: Randomized Clinical trial To compare post-restorative sensitivity between titania nanoparticle reinforced bonding agent and bonding agent without nanoparticles in posterior composite restorations. Participants aged 18 years and above with Class-I and Class-II Carious lesions are allocated in two groups. Group A will undergo composite restoration with Nanoparticles incorporated in bonding agent. Group B will undergo restoration without nanoparticles in bonding agent.
The objectives were to evaluate the antibacterial effect of self-etching adhesives on carious dentin and the clinical results of restorations in a randomized controlled clinical trial. 104 carious deciduous molars (n=92) were randomly allocated to receive one of the self-etching adhesives: Clearfil SE Bond - control (CB - n =53) or Clearfil SE Protect containing MDPB (CP - n=51) after caries removal selective. Clinical, radiographic, photographic and plaster model assessments (n=53 deciduous molars, CB=29, CP=24) of resin restorations were performed at baseline and at 6, 12, and 24 months. Dentin samples (n=51 deciduous teeth; CB=24 and CP=27) were collected immediately after excavation of carious dentin and 3 months later, and cultured for mutans streptococci - (MS), lactobacilli (LB) and total microorganisms (TM). Data were statistically analyzed (p<0.05).
