Interest of decompression in orthodontics: Case report of a keratocyst during childhood.

Keratocysts, also known as keratocystic odontogenic tumors (KCOT), make up 7% of all odontogenic cysts and develop asymptomatically in most cases. Enucleation is the benchmark treatment. However, there are surgical alternatives.

[Influence of trigeminal nerve lesion on facial growth: study of two cases of Goldenhar syndrome].

Introduction: This cases report confirms the hypothesis that embryonic and maxillofacial growth are influenced by the peripheral nervous system, including the trigeminal nerve (V). So, it's interesting to use the stigma of the trigeminal nerve as landmarks to analyze the maxillofacial volume and understand its growth. The aim of this study is to evaluate the validity of the three-dimensional cephalometric analysis of Treil based on trigeminal landmarks.

Effect of fixed orthodontic appliances on salivary microbial parameters at 6 months: a controlled observational study.

Objective: The aim of this study was to assess the microbial changes in children with fixed orthodontic appliances compared with a control group of children without orthodontic treatment.

Material And Methods: Ninety-five children, aged between 12 and 16 years, participated in this study. Forty-eight subjects were fitted with fixed orthodontic appliances and forty-seven were free of any such appliances.

Asynchronous dentofacial development and dental crowding: a cross-sectional study in a contemporary sample of children in France.

Background: The causes of dental crowding are not fully understood, but it may result from an evolutionary trend towards reduced facial volume, without a proportional reduction in tooth sizes. Most previous studies conducted among modern humans have revealed a very low or non-existent correlation between tooth size and jaw size. Cross-comparison between dental age and facial skeletal age could help to provide better knowledge of the dynamic process of dental crowding.

Ethics in systematic reviews.

Since its introduction by the Nuremberg Code and the Declaration of Helsinki, the place held by ethics in biomedical research has been continuously increasing in importance. The past 30 years have also seen exponential growth in the number of biomedical articles published. A systematic review of the literature is the scientific way of synthesising a plethora of information, by exhaustively searching out and objectively analysing the studies dealing with a given issue.

Cochrane systematic reviews in orthodontics.

Introduction: The Cochrane Collaboration is an international scientific not-for-profit organization the purpose of which is to produce and distribute systematic reviews of randomized clinical trials. The aim of this paper is to list the different existing Cochrane systematic reviews in the field of dentofacial orthopedics (DFO) and to analyse their main features.

Material And Methods: The choice of Cochrane systematic reviews based on dentofacial orthopedics was made from the exhaustive list published by the Cochrane Oral Health Group.

[Teenager information on orthodontics with fixed appliances].

Thoughts and questions are proposed on the reality of consent by adolescents. This reflection, ethical in nature, confronts the medico-legal facet of the care contract, which is specific when minors are concerned, with the psychological aspect, so particular when an adolescent is involved. How do we treat adolescents who have not reached their majority? Beyond this quasi-philosophical questioning on the inter-human care relationship, we put forward very practical elements towards answers.

[Three-dimensional cephalometry: applications in clinical practice and research].

A 3D cephalometric analysis method from scanner acquisition has been developed thanks to a long collaboration between Dr Treil and the Department of Orthodontics in Toulouse III University. It allows a perfect knowledge of maxillo-facial architecture using fourteen landmarks related to the neuromatricial axis of facial growth. These landmarks can be identified without ambiguity.
