Les lésions cervicales non carieuses sont des destructions chroniques des tissus durs de la dent d’origine non bactérienne contrairement à la carie dentaire. Elles sont fréquemment rencontrées en pratique clinique et se présentent sous différentes formes : abrasion, abfraction et érosion. Les facteurs étiologiques sont multiples et combinés.
Le but de cette étude était de déterminer la prévalence et les facteurs étiologiques des lésions cervicales non carieuses dans une population sénégalaise. Pour cela nous avons consulté 655 patients âgés de 13 à 77 ans dans cinq centres de santé de la région de Dakar. Nos résultats ont montré une prévalence globale de 17,10 %. L’abrasion représente la lésion la plus rencontrée avec 77,70 % suivie de l’abfraction avec 12,50 % et l ‘érosion 9,80 %.
The non carious cervical lesion (NCCL) is a loss of tooth tissue at the neck of affected teeth that is unrelated to tooth decay. They are commonly encountered in clinical practice and present in a variety of forms.
The purpose of this paper is to determine the prevalence of the NCCL in a Senegalese population. From 655 patients, 112 with cervical lesions were identified i.e. a global prevalence of 17.10 %. The prevalence rate for abrasion was reported to be 77.70 %, 12.50 % for abfraction and 9.80 % for erosion. Etiological factors were studied for abrasion and erosion. 54 % of the patients with abrasion used their toothbrush horizontally. For erosion, only external factors were identified: consumption of acidic drinks (9 patients) or alcohol (1 patient) and professional environment (1 patient). Dentists should consider these lesions in their daily practice.
