The primary teeth begin to form in utero at about six weeks. Hard tissue formation occurs in all primary teeth by the 18th week in utero. 3. The permanent teeth begin to develop at approximately four months of age in utero. Maxillary and mandibular first molars begin to calcify at birth.

Dry socket (alveolar osteitis) is a painful condition that occurs when the blood clot at the site of a tooth extraction fails to develop or is dislodged. The standard treatment involves gentle irrigation to remove debris and then placing a medicated dressing to soothe the pain and protect the area. Curettage is generally avoided as it can further delay healing,

Streptomycin is considered a narrow-spectrum antibiotic, primarily effective against Gram-negative bacteria and Mycobacterium tuberculosis. Ampicillin, chloramphenicol, and tetracycline are all classified as broad-spectrum antibiotics because they are effective against a wide range of both Gram-positive and Gram-negative bacteria.

The destruction of microorganisms on living tissues, as long as there is contact between the tissues and the antimicrobial agent, denotes antisepsis (option 2). Antisepsis refers to the application of antimicrobial agents to living tissues to reduce the possibility of infection, sepsis, or putrefaction.

1. Sterilization:

   • This is the process of completely eliminating all forms of microbial life, including bacteria, viruses, fungi, and spores, from an object or surface. Sterilization is typically achieved through methods such as autoclaving (steam under pressure), dry heat, chemical sterilants, or radiation. Sterilization is used for medical instruments, laboratory equipment, and other items that must be free of all microorganisms.

2. Antisepsis:

   • Antisepsis refers to the application of antimicrobial agents to living tissues to reduce the risk of infection, sepsis, or putrefaction. Antiseptics are used on skin and mucous membranes to prevent infection during surgical procedures, wound care, and other medical interventions. Common antiseptics include alcohol, iodine solutions, and chlorhexidine.

3. Sanitization:

   • Sanitization is the process of reducing the number of microorganisms on surfaces or objects to a level considered safe by public health standards. This does not necessarily eliminate all microorganisms but reduces them to a level that minimizes the risk of infection or disease. Sanitization is commonly used in food service, public restrooms, and other environments where hygiene is important.
