Summary
This study defines giant mandibular ameloblastoma (GMA) using objective criteria to aid in diagnosis and treatment. The proposed criteria help manage these large jaw tumors more effectively.
Area of Science:
- Oral and Maxillofacial Surgery
- Oncology
- Reconstructive Surgery
Background:
- The term giant mandibular ameloblastoma (GMA) lacks clear definition in medical literature.
- Existing criteria for GMAs are arbitrary and do not aid clinical decision-making or management.
Purpose of the Study:
- To establish objective, clinically relevant criteria for identifying giant mandibular ameloblastomas (GMAs).
- To improve the management and decision-making process for GMAs.
Main Methods:
- Retrospective analysis of 16 ameloblastoma patients from August 2012 to September 2016.
- Application of proposed criteria to identify 11 cases of GMAs.
Main Results:
- Segmental mandibular defects after resection measured 7-11.5 cm (mean 9.3 cm).
- No recurrence observed in 11 identified GMAs during a mean follow-up of 10.7 months.
Conclusions:
- Objective criteria for GMAs reduce ambiguity and simplify treatment planning.
- Inclusion criteria for GMAs: segmental defect >6 cm with 1 cm margin, involving central mandible.

Psychology is the scientific discipline dedicated to understanding both observable behavior and the internal mental processes underlying such behavior. It aims to comprehend human nature and apply this understanding to solve practical problems, enhance well-being, and improve societal outcomes. An example of psychology's application is the study of prosocial behavior, such as why and under what conditions individuals might help strangers in need. This process involves describing observed...

Social psychology investigates how the presence and actions of others influence individual behavior, cognition, and emotion. Examining the social environment's impact provides a scientific framework for understanding how individuals perceive others and are, in turn, influenced by them. This field seeks to uncover the underlying principles guiding social interactions, exploring phenomena such as conformity, obedience, and prosocial behavior.Core Themes in Social PsychologyOne central focus of...

01:28Piecewise-Defined Functions
292
Piecewise defined functions are mathematical models where different expressions define a function over distinct intervals of the domain. These functions are useful for representing systems with varying behaviors depending on input values.For example, the function: uses a linear rule for inputs less than or equal to –1 and a quadratic rule for values greater than –1. Although it has two formulas, it still defines a single function.Another common type is the absolute value...

01:29Rules for Defining Functions
370
A relation is a function if each input x is associated with exactly one output y. For example, the equation y = 2x + 5 defines a function because every value of x yields a unique y. However, x = y² + 1 is not a function of x, since a single x-value, such as x = 2, corresponds to two possible y-values: y = 1 and y = -1.The vertical line test helps determine whether a graph represents a function. If a vertical line intersects a curve more than once, the curve fails...

01:01Polymers: Defining Molecular Weight
3.8K
Unlike small molecules with definite molecular weights, polymers are a mixture of individual polymer chains of varying lengths, each with a unique molecular weight. So, the molecular weight of a polymer is expressed as an average value based on the average size of the polymer chains. The two most common forms of averages used for polymers are the number average molecular weight and weight average molecular weight.

02:17Separation of Sister Chromatids
4.5K
At the transition from prophase to metaphase, there is a reduction in cohesion along the chromosomal arms, resulting in the resolution of sister chromatids. However, residual cohesin connections remain to hold the sister chromatids together until the transition from metaphase to anaphase. The residual connection prevents any premature separation of sister chromatids, blocking the risks of aneuploidy within the daughter cells.
