Summary
The pH of pus in periapical abscesses was measured, revealing a generally acidic environment. This study provides crucial data on the chemical environment of dental infections.
Area of Science:
- Endodontics
- Microbiology
- Biochemistry
Background:
- Periapical abscesses are common dental infections.
- Understanding the chemical environment within abscesses is important for treatment.
Purpose of the Study:
- To determine the pH of pus collected from periapical abscesses.
- To investigate potential correlations between pH and patient demographics.
Main Methods:
- Pus samples were collected from 40 patients with periapical abscesses.
- A pH meter was used to measure pus pH immediately after aspiration.
- Patient age and gender were recorded.
Main Results:
- The mean pH of periapical abscess pus was 6.68 ± 0.324 (range: 6.0–7.3).
- No statistically significant differences in pH were observed based on gender or age.
- Some samples exhibited neutral or alkaline pH values.
Conclusions:
- Pus from periapical abscesses is typically acidic.
- Variations in pH, including neutral and alkaline readings, were noted in a subset of samples.
- Further research may explore the clinical implications of varying pus pH in periapical infections.

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
