Summary
Dental adhesives have evolved significantly, with modern formulations returning to Oskar Hagger's 1949 concept of molecular interaction for bonding. This approach, using acidic monomers, enhances dental restoration adhesion.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
- Restorative Dentistry
Background:
- Dental adhesives have a long history, originating from ancient Mayan cements.
- Oskar Hagger pioneered early adhesive concepts in 1949 with Sevriton Cavity Seal.
- Modern dental adhesives initially focused on micromechanical retention via acid etching.
Purpose of the Study:
- To trace the historical evolution of dental adhesives.
- To highlight Oskar Hagger's foundational contributions to adhesive dentistry.
- To examine the resurgence of molecular interaction concepts in contemporary dental adhesives.
Main Methods:
- Historical review of dental adhesive development.
- Analysis of Oskar Hagger's early adhesive formulations and concepts.
- Comparison of historical and modern adhesive strategies, focusing on bonding mechanisms.
Main Results:
- Oskar Hagger developed Sevriton Cavity Seal in 1949, an acidic adhesive interacting at a molecular level with tooth structure.
- Hagger's molecular interaction concept predates and contrasts with the dominant micromechanical retention paradigm.
- Current advancements in dentin adhesives show a return to Hagger's principles of chemical bonding.
Conclusions:
- Oskar Hagger is recognized as a key figure, the "Father of Modern Dental Adhesives."
- The principles of molecular interaction for dental adhesion are proving vital for newer adhesive generations.
- Hagger's foundational concept continues to influence and drive innovation in dental adhesive technology.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:14Adhesion
Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow glass...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:24Adherens Junctions
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

01:14Cell Adhesion in Plants
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose, and...

01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
