Cefdinir, sold under the brand name Omnicef among others, is an antibiotic used to treat pneumonia, otitis media, strep throat, and cellulitis. It is a less preferred option for pneumonia, otitis media, and strep throat which may be used in those with a severe allergy to penicillin. It is taken by mouth.Common side effects include diarrhea, nausea, and a skin rash. Serious side effects may include Clostridioides difficile infection, anaphylaxis, and Stevens–Johnson syndrome. Use in pregnancy and breastfeeding is believed to be safe but has not been well studied. It is a third-generation cephalosporin and works by interfering with a bacterias ability to make a cell wall resulting in its death.It was patented in 1979 and approved for medical use in 1991. It is available as a generic medication. In 2019, it was the 159th most commonly prescribed medication in the United States, with more than 3 million prescriptions. Medical uses
Therapeutic uses of cefdinir include otitis media, soft tissue infections, and respiratory tract infections, including sinusitis, strep throat (note: no documented resistance of Group A Streptococcus to penicillin has ever been reported, and penicillin or amoxicillin is preferred except in penicillin allergic patients), community-acquired pneumonia, and acute exacerbations of bronchitis. Susceptible organisms
Cefdinir is a bactericidal antibiotic of the cephalosporin class of antibiotics. It can be used to treat infections caused by several Gram-negative and Gram-positive bacteria. Bacterial susceptibility and resistance
Cefdinir is a broad-spectrum antibiotic and has been used to treat infections of the respiratory tract including pneumonia, sinusitis, and bronchitis.
If there are concerns around aesthetics or clinical consequences such as dentinal hypersensitivity, a dental restoration (white filling) may be a suitable treatment option. Aside from restoring the lesion, it is equally important to remove any other possible causative factors. Adjustments to the biting surfaces of the teeth alter the way the upper and lower teeth come together, this may assist by redirecting the occlusal load. The aim of this is to redirect the force of the load to the long axis of the tooth, therefore removing the stress on the lesion. This can also be achieved by altering the tooth surfaces such as cuspal inclines, reducing heavy contacts and removing premature contacts. If bruxism is deemed a contributing factor an occlusal splint can be an effective treatment for eliminating the irregular forces placed on the tooth. Controversy
Abfraction has been a controversial subject since its creation in 1991. This is due to the clinical presentation of the tooth loss, which often presents in a manner similar to that of abrasion or erosion. The major reasoning behind the controversy is the similarity of abfraction to other non carious lesions and the prevalence of multiple theories to potentially explain the lesion. One of the most prevalent theories is called "the theory of non-carious cervical lesions" which suggests that tooth flexion, occurring due to occlusion factors, impacts on the vulnerable area near the cementoenamel junction. This theory is not widely accepted among the professional community as it suggests that the only factor is occlusion.
