COVID-19 and Water transmission

Anisha ValliLeave a comment

Can the virus exist in drinking water?

Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate the SARS-CoV-2 virus that causes COVID-19.

Can the SARS-CoV-2 virus spread through pools and hot tubs?

Proper operation, maintenance, and disinfection (e.g., with chlorine and bromine) of pools and hot tubs should remove or inactivate the virus that causes COVID-19. However, chlorinated pools do not decrease your risk of droplet transmission of the virus (being coughed or sneezed on) and we recommend to practice social isolation and quarantine as recommended by the health authorities in your country during this pandemic.

What about sewers, gutters, and feces?

The virus that causes COVID-19 has been detected in the feces of some patients diagnosed with COVID-19. The risk of transmission is expected to be low. There have been no reports of fecal-oral transmission of COVID-19 to date.

Transmission of COVID-19 through sewage may be possible, there is no evidence to date that this has occurred. SARS, a similar coronavirus, has been detected in untreated sewage for up to 2 to 14 days. In the 2003 SARS outbreak, there was documented transmission associated with sewage aerosols. Therefore, wastewater and sewage workers should use standard practices, practice basic hygiene precautions, and wear personal protective equipment.

Odontomas

Dr.Mehnaz1 Comment

• Composed of proliferating odontogenic epithelium in a cellular ectomesenchyme resembling the dental papilla.

• Odontomas are composed of all mature components of dental hard & soft tissues: Enamel, dentin & pulp.

• Because of their limited slow growth and well differentiation – considered hamartomas rather than true neoplasms

Clinical Features:

1. Interfere with eruption of permanent teeth.

2. No sex predilection

3. Age: 2nd decades

4. Asymptomatic in nature

5. Associated with impacted, malpositioned teeth.

6. Cause malformation and displacement of adjacent teeth

Intra-oral view showing erupted odontomas
Radiographically,
  • Early lesion: Radiolucent with smooth, well defined contours between the roots of teeth.
  • Later stage: Radiopaque.

Types of Odontomas:

  • Complex odontoma (less common)
  • Compound Odontoma

1. Complex Odontoma:

• Location: Posterior region of either Jaw. (70% – Mandibular Molars)

• Composed of haphazardly arranged dental hard and soft tissue with no resemblance to normal tooth.

• Arises from normal tooth follicle.

• Radiographically, Sunburst opacities with thin uniform radiolucent rim.

2. Compound Odontoma:

• Location: Anterior maxilla (62% – unerupted canine)

• Collection of small radio-opaque masses, some/all may be tooth like structures “denticles“

• Formed by exuberant growth of dental lamina or proliferation of enamel organ

• Radiographically, cluster of multiple tiny toothlike structure within a fine radiolucent rim.

Histological features:

• Connective tissue capsule around odontoma is similar in all aspects to follicle surrounding normal tooth.

• Presence of ghost cells also found.

Differential Diagnosis:

  • Periapical cemental dysplasia
  • Cemento-ossifying fibroma
  • Focal sclerosing osteitis
  • Cementoblastoma

Treatment: Surgical Removal
