Unlabelled: There has been a move in recent years for operative dentists to use the benefits of adhesive technology when placing dental amalgam restorations. This paper describes the potential advantages of the bonded amalgam technique. These benefits include decreased microleakage between the cavity wall and the restorative material. This, in turn, may decrease post-operative sensitivity, pulpal inflammation and the incidence of recurrent caries. Extra retention for the restoration may also be provided and the need for cavities to rely on traditional retention and resistance form may be decreased or even eliminated, thus conserving precious tooth tissue. If the restoration is bonded then flexure during function in teeth may be decreased and, in the case of teeth exhibiting a cracked cusp, this may alleviate or eliminate symptoms. Bonding may also provide support to weakened tooth tissue which otherwise would have to be removed, so rendering cavities more conservative, and may increase the fracture resistance of the tooth. Clinical examples are included to illustrate some of these benefits.
Clinical Relevance: The use of adhesives to bond amalgam to tooth tissue offers potential advantages, although some of the current evidence is equivocal about their routine use.

Periodontitis is a chronic inflammatory condition mainly caused by the interaction between the host immune system and periodontal tissue pathogens, and may lead to consequences, such as alveolar bone defects and tooth loss. Incomplete bacterial removal, persistent inflammation and high reactive oxygen species (ROS) environment are the main challenges for periodontal tissue repair and alveolar bone regeneration. In this study, an injectable composite microgel (Gelatin methacryloyl-Phenylboronic acid/Hydroxyadamantane, GPH) loaded with antimicrobial peptide (AMP) and cerium dioxide (CeO) microspheres was developed to achieve a synergistic function of bacteriostasis, immunomodulation, and ROS removal.

Renal osteodystrophy is commonly seen in patients with chronic kidney disease (CKD) due to disrupted mineral homeostasis. Given the impaired renal function in these patients, common anti-resorptive agents, including bisphosphonates, must be used with caution or even contraindicated. Therefore, an alternative therapy without renal burden to combat renal osteodystrophy is urgently needed.

Materials And Methodology: Sixty-eight noncarious single-rooted teeth were collected and decoronated at the level of cementoenamel junction with a diamond disc. All specimens were randomly divided into three experimental groups - Manual ProTaper Universal (PTU; Dentsply Maillefer, Ballaigues, Switzerland), Protaper Gold (PTG; Dentsply Maillefer), Waveone Gold (Dentsply Maillefer) and one control group of 17 teeth each.

The reduction in alveolar ridge height and width after tooth extraction poses a substantial challenge for dental implant restoration. This study aimed to observe the roles of S100A8 in the inflammatory response and bone resorption following tooth extraction. Rat mandibular second molars were extracted.

It arises from friction between the tongue and lower incisors during sucking, potentially worsening into a keratinized lesion if the cause is not addressed. This report details the case of a 1-year-6-month-old male with hydrocephalus, cleft palate, corpus callosum dysgenesis, neuropsychomotor developmental delay, and tracheostomy and gastrostomy needs.
