OBJECTIVE :
To determine the quality of maintained dental records and analyze the knowledge and use of them in any of forensic or medico-legal purposes by Sirte's dental practitioners.

MATERIALS AND METHODS :
A cross-sectional survey was conducted in a sample of 70 dental practitioners in Sirte and data were collected through a structured questionnaire. The data sogathered were subjected for descriptive analysis.

RESULTS :
80 % of surveyed dentists-maintained records but only 10% of them kept the complete dental record. When asked about duration of maintained records, 61% of them kept for less than three years. About 56% of sample used paper prepared form as methodto maintain dental records and only 20% usedcomputer software. 91% of practitioners did not think that mandatory to legally maintain the dental records, when asked about whether the legal rights of owning the dental records in Sirte is it medico-legallyimportant, 98% response was yes. The significance of dental records for forensic needs was evaluated, only 18% dental practitioners were asked to produce any records in forensic court of law. Only 3% askedto produce dental file for forensic purposes. 55% of practitioners did not know how to estimate the age of individual. About 94% of sample did not have any training in forensic dentistry. All the surveyed dentists' response was yes, when asked about the importance of forensic dentistry in Libya.

CONCLUSION :
The present study showed non-maintenance or poor quality of dental records maintained. Our study revealed that the dentists in Sirte are not prepared for any kind of forensic and medico-legal need if it arises due to the poor knowledge, attitude and lack of practice of forensic odontology.

Peripheral giant cell granuloma is a pathological entity of reactive non-neoplastic oral mucosal hyperplasia of unconfirmed etiology, including chronic irritants and traumatic factors. Itappears as a localized gingival growth, sessile or pediculated, purplish red in color, firm or spongy in consistency, and smooth in appearance. The consultation’s reason is most often functional caused by discomfort rather than pain. The diagnosis is based on the pathological examination characterized by dispersed mononuclear cells and multi-nucleated giant cells of the osteoclast-like type. The treatment is surgical by excision of the gingival mass and mucogingival management of the site.
The objective of this work is to present the periodontal management of a peripheral giant cell granuloma in a 50-year-old patient, with a clinical follow-up of one year.

Since ancient times, implantology has continued to evolve. The discovery and establishment of the concept of osseointegration by Professor Brånemark and al.marked the beginning of the contemporary period or called Brånemarkian era. This period has beencharacterized by a set of paradigms, mainly the 2-step surgical protocol and deferred loading of the implant. In fact, these two principals were considered essential to the success of implant treatment. However, due to several associated factors (technological advances, developmentof microdentistry and increasing patient demands), these paradigms have been evolved. Thus, the emergence of new perspectives as immediate loading, immediate extraction-implantation, flapless surgery, etc., initially not recommended, was possible, marking the birth of the current period so-called post Brånemarkianimplantology.This has many advantages, including meeting the aestheticand functional demands of patients in the shortest possibletime. This article aims to review the evolution of Brånemark implantology during the last thirty years.

INTRODUCTION :
Dento-maxillary disharmony is one of the most frequentlyencountered anomalies in the Dento-facial Orthopedics department of the CHU-CNOS. A study whose objectivewas to determine the epidemiological and clinical aspects of dento-maxillary disharmony due to dental excess was conducted.

METHODOLOGY :
This was a descriptive cross-sectional study withprospective collection carried out over a period of 6 months in the Dento-Facial Orthopedics department of the National Center for Odonto-Stomatology University Hospital (CHU-CNOS) in Bamako.

RESULTS :
The study enabled us to collect 139 patients including 84 cases of DDM by dental excess,that is a frequency of 60.43%. Nearly half of the patients were in the 12-19 age group, ie 45.2%. The DDM was anterior in 95.2% to the maxilla. Significant associations were found between excess DMD and family history, the shape ofthe mandibular arch as well as with associated alveolar anomalies.

CONCLUSION :
The present study allowed to say that the DDM bydental excess can be associated with all the malocclusionsof the classification of Angle. Significant aestheticdamage, its impact on psychosocial balance and quality of life, remains one of the fundamental factors inspiringthe demand for care. Its early management is sometimes necessary to avoid more complex orthodontic treatments later.

Faced on the aesthetic emergency, prosthetic rehabilitation with an immediate prosthesis is the solution of choice to consider. Indeed, this type of rehabilitation restores both aesthetics and function and it ensures the psychological comfort of the patient.
The technical and operational difficulty of this kind ofrehabilitation means that it is not always successful.
The objective of this work is to focus on the failures of immediate complete denture and to highlight allthe essential tools for therapeutic success.

Key words: Immediate complete denture-difficulty-failure.

The objective of our study is to determine the prevalence of the orthodontic anomalies among a population ofhigh-school teenage pupils in Beni Mellal, Morocco, toestablish the possible correlations and associations between the various malocclusions according to the variables of age, sex and socio-economic level and to compare the results with those of other similar studies.
We studied the prevalence on a sample which was randomly selected and which included 1042 high-school pupils from a secondary school in Beni Mellal.
The results have shown that approximately 77,73% had a normal occlusion and that 22,26% presented at least one malocclusion. Indeed, 13,33% of the examined pupils had malocclusions of class 2 (division 1:7,77%; division 2:5,56%) and 7,48% had malocclusions of class 3.
Approximately 57,00% of the sample presented a normal overbite, 29,07%, an overbite ? 3mm while only 13,91% had an overbite ? 2mm.
Crowding was the most frequent anomaly with a percentage of 47,88%, whereas, the results concerning the midlinediastemas show that 11,42% of the subjects presented diastemas. The values of anterior and posterior crossbite are respectively 9,69% and 7,58%.
Therefore, teenagers from Beni Mellal need some health care in terms of orthodontic treatments.
