Psychosurgery

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Electroconvulsive Therapy

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Summary

Hemisection, the separation of a two-rooted tooth, can preserve tooth structure and bone when periodontal disease causes attachment loss. This procedure offers an alternative to extraction for molars with extensive decay.

Area of Science:

Dentistry
Periodontology
Oral Surgery

Background:

Untreated inflammatory periodontal disease leads to attachment loss, potentially affecting multi-rooted teeth.
This attachment loss can compromise the bifurcation or trifurcation of teeth, especially mandibular molars.

Observation:

Hemisection involves the separation or removal of a root and crown in a two-rooted tooth, typically a mandibular molar.
This case report discusses hemisection as a treatment for molars with extensive decay threatening tooth loss.

Findings:

Hemisection can preserve natural tooth structure and alveolar bone compared to extraction.
Careful case selection is crucial for the long-term success of hemisection procedures.

Implications:

Hemisection presents a viable alternative to tooth extraction and implant therapy.
This treatment option should be discussed with patients facing extensive decay or advanced endo-perio lesions.
