Subantral recovery technique (T.R.O.A.S.)

Extensive pneumatization of the maxillary sinus can limit rehabilitation with maxillary implants. During the last 30 years, several graft addition techniques have been proposed to solve this problem. A technique without graft has been developed by the authors and the results of this technique are analyzed.     

Gingival risks of fixed prostheses at the Institute of Odontology and Stomatology of Dakar (I.O.S.)]

The realisation of a bridgework involves a direct action on the gingival marginal edge. It is submitted to peremptoriness of execution that one of the objectives is to respect the periodontium with a great rigour. In the opposite case it can become a greater aggression agent, source of prosthetic failures we carried out this report in order to evaluate in the framework of a pedagogic operational programme of crown and bridge prosthesis, the superficial periodontal risks linked to the preparation of the abutment teeth and to the prosthetic chain. We examined a randomised sample of 50 patients chosen from the Dakar LOS prosthetic consultation. On the periodontium initially sound we noted inflammatory lesions of the superficial periodontium from the beginning to the end of the treatment we used the Russel periodontal index. The whole individual scores summarised on a collective chart have been submitted to the statistical analysis of the independence by using the chi-square test. The population consulting in bridge work at the Dakar LOS is relatively young, 33 years in a average with a sex ratio of 1.17 and it shows a moderate (60% of the cases) and severe periodontal seizure (40% of the cases) dealing significantly with the type of prosthesis and the axial and occlusal morphology of the prosthesis pieces. This study shows that prosthesis rehabilitation in the frame work of a clinical training at the Dakar I.O.S. includes relatively high risks of periodontium aggression that we would minimise by setting more correctly the indications of the bridge work and by bringing more rigour to the record and the postpone of the patients occlusion in the laboratory conception of the prosthesis pieces.

Abstract

Aim: To determine the relationship between treatment need assessment scores of orthodontists, general practitioners, and pediatric dentists.

Study design: Observational.

Sample: Ten general dental practitioners, 18 orthodontists and 15 pediatric dentists reviewed 137 dental casts and recorded their opinion on whether orthodontic treatment was needed.

Results: We found a high level of agreement between pediatric dentists, orthodontists and general practitioners (Kappa range 0.86–0.95). Between the groups, the amount of agreement was lower.

Conclusions: Orthodontists, general dental practitioners, and pediatric dentists in this sample exhibit high levels of agreement on orthodontic treatment need.     

The O.M.E.N.S. classification of hemifacial microsomia.

The wide spectrum of anomalies associated with hemifacial microsomia (HFM) has made systematic and inclusive classification difficult. We propose a nosologic system in which each letter of the acronym O.M.E.N.S. indicates one of the five major manifestations of HFM. O for orbital distortion; M for mandibular hypoplasia; E for ear anomaly; N for nerve involvement; and S for soft tissue deficiency. The O.M.E.N.S. system is easily adapted for data storage, retrieval, and statistical analysis. A retrospective study of 154 patients with HFM classified according to the O.M.E.N.S. system confirmed the concept that the mandibular deformity is the cornerstone of the anomaly. Statistical analysis demonstrated a positive association between mandibular hypoplasia and the severity of orbital, auricular, neural, and soft tissue involvement. This study did not confirm a previously reported predominance of gender or sidedness. Analysis of statistical correlations failed to substantiate a Goldenhar variant as a syndromic entity. Our analysis showed that palatal deviation is probably caused by muscular hypoplasia and not by weakness of a particular cranial nerve.
