Filter by:The goal of this randomized clinical trial is to test the effect orally administration of Probiotics based on Lactobacillus rhamnosus LR04 and Lactobacillus plantarum LP14 as adjuvant in caries prevention in subjects who can not properly perform oral hygiene procedures. The main questions it aims to answer are: - QUESTION 1: orally administered probiotics based on the previous strains could represent a useful tool in support of special needs patients in tooth decay prevention? - QUESTION 2: orally administered probiotics based on the previous strains could ameliorate salivary pH management? Partecipants in the test group will take the test probiotic for 90 days in adjunction of the routinary oral hygiene procedures. Partecipants in the positive controlled group will take the placebo for 90 days in adjunction of the routinary oral hygiene procedures. Partecipants in the negative control group will perform only the routinary oral hygiene procedures. Researchers will compare 3 groups to see if orally administered probiotics based on L. rhamnosus and L. plantarum may help in the management of clinical status and salivary pH levels.
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.
Around 40 people will participate in the study. The study participants will be recruited from service homes in the City of Helsinki. The subjects will be randomized into two groups. One of the groups will receive daily photodynamic Lumoral treatment for 2 months in a home care unit according to a separate instruction manual. At the beginning of the study, all subjects will receive an oral cleaning and will also be provided with electric toothbrushes. In addition, residents and care home personnel will be instructed on daily tooth cleaning. During the study, all participants will undergo clinical measurements and an assessment of the oral inflammatory load. The samples will be stored for later analysis. In addition, residents or care home personnel answer questions about oral self-care. These measurements and examinations will be carried out at the start of the study and two months after the start of the study. After the end of the study, participants will continue to be treated according to their usual care and individual care plan.
The aim of the study is to evaluate the knowledge, attitude, and practice of a group of dental practitioners from Cairo and Riyadh regarding caries risk assessment and management.
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.
Class II caries affects proximal surfaces of premolars and maintain their anatomical proximal contact of tooth, is important to avoid food impaction in the interdental area for protection of periodontium and occurrence of secondary carious lesion.Different types of Matrix band system are used to restore tooth cavities with missing proximal walls, including flat or pre-contoured bands, retainer-fixed circumferential systems, and sectional matrices, and either metal or plastic matrices which produces good contours and contacts for use with amalgam and can also be employed for insertion of composite resin.This study aimed at assessing the influence of different matricing techniques :either sectional matrix or circumferential matrix and the influence of operator experience on reproduction of optimum proximal contacts for posterior proximal resin composite restorations.
Isolation is essential for the successful placement of esthetic restoration to avoid any contamination of cavity with saliva ,secreation,and blood dental . This study is comparison of optradam and convetional rubberdam system.The aim of this study is to investigate which rubberdam system is better accepted by patients and dentists
There is limited data available on VITA AMBRIA glass ceramic , so this study is conducted to investigate the esthetic parameters of this new glass press system.
Of all the various pulpotomy medicaments that have been studied till to date, three agents have been selected for this study to compare their efficacy. CH being the control, MTA being one of the most recommended biomaterial and PRF that in addition to being a biomaterial is an autologous agent. Uptil now there have been no prospective trials using these three pulpotomy agents in mature permanent teeth with irreversible pulpitis in our part of the world and even the international studies that have been done utilized different methodologies with no unanimous conclusion. This is the reason that at present this treatment regime (pulpotomy) showing better perspectives cannot be presented with confidence as a predictable treatment option to the patients with irreversible pulpitis. By virtue of this study this challenge is being undertaken. Hypothesis: ALTERNATE HYPOTHESIS There is a difference between the efficacy of the PRF, MTA and CH when used as pulpotomy medicaments in mature permanent teeth with irreversible pulpitis NULL HPOTHESIS There is no difference in efficacy of the PRF, MTA and CH when used as pulpotomy medicaments in mature permanent teeth with irreversible pulpitis
