Abstract
AIMS Cohen syndrome (CS) is an uncommon autosomal recessive disorder due to mutations in vacuolar protein sorting 13B, with an intermittent presence of neutropenia. Contrary to other clinical phenotypic features, oral health has been little investigated in CS. We described oral health and dental hygiene in a cohort of CS patients. METHODS AND RESULTS Twelve CS patients with neutropenia (<1500/mm3 ) were recruited in the dental department of Dijon University Hospital (France). Patients underwent oral examination, and blood samples were collected. Oral health markers were described and compared between patients with moderate and severe neutropenia (<500/mm3 ). In 12 patients (mean age = 21.1 years, SD = 13.7, six females), 45.5% brushed at least twice daily their teeth, and the same percentage annually visited a dentist. Dental plaque index was high (mean = 1.7, SD = 1.4). So was the number of lost teeth per patient, notably among adults (mean = 13.8, SD = 9.8). Elevated markers of periodontitis were noted as percentage of bleeding dental sites (mean = 70.2%, SD = 45.2%) or Gingival Index (mean = 2.2, SD = 1.0). The severity of neutropenia was correlated to the level of tooth-loss (P = .03). CONCLUSION This study highlighted in CS patients worrisome oral health and dental follow-up in the context of intellectual disability with behavioural anomalies. More attention is needed by care-givers on oral condition in CS.

Abstract
This study evaluated the effect of microabrasion and polishing on the microhardness and roughness of bovine enamel, and the effect of artificial saliva on the hardness of enamel. Bovine enamel blocks were used, forming the groups (n = 48): GI-37% phosphoric acid and pumice, GII--Opalustre, and GIII--Whiteness RM. The groups were divided into different subgroups: (a) diamond paste, (b) fluoride prophylactic paste, and (c) without polishing. Hardness tests were carried out at the following set times: (T1) initial, (T2) after microabrasion and polishing, (T3) after immersion in artificial saliva for 24 h; and (T4) after seven days of immersion. Surface roughness tests were performed. The obtained data were analyzed by two-factor ANOVA and Tukey's test with significance of 5%. Microhardness increased in T2; without polishing, only groups GII and GIII showed an increased microhardness. T3 did not differ from T4; GI, GII and GIII did not provide surface roughness that differed from each other; and all microabrasive systems followed by polishing showed a higher surface smoothness compared with the control groups. It is concluded that microabrasion followed by polishing provided higher hardness and better surface smoothness of the enamel. However, immersion in artificial saliva was not able to increase the enamel hardness.
