Effect of personality traits on the oral health-related quality of life in patients with oral mucosal disease.

OBJECTIVES: The aim of this study was to assess the relationship between oral health-related quality of life, the nature of mucosal disease, and personality traits. METHODS: One hundred forty-nine patients seeking care for oral mucosal disease were recruited in this cross-sectional study conducted at the University Clinic of Dentistry in Vienna from June to December 2013. All participants agreed in answering two questionnaires: the Oral Health Impact Profile German version (OHIP-G), which assessed the perceived limitations of oral health-related quality of life and the Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI), which evaluated five personality domains. A multiple linear regression was applied to examine the potential influence on OHIP scores. RESULTS: Bullous/erosive mucosal diseases and oral lichen planus patients (n = 73, 49% of total) reported the highest impact on oral health-related quality of life (OHIP total score 49.3 ± 35.7, p = 0.02). A highly significant influence of neuroticism, as a personality trait, was observed on oral health-related quality of life (p = 0.001). Women had significantly more restrictions (OHIP score 45.3 ± 32.2) compared to men (32.6 ± 30.1, p = 0.009). CONCLUSIONS: Psychosocial factors such as personality traits, especially neuroticism, are significantly associated with quality of life ratings in patients with mucosal disease. CLINICAL RELEVANCE: Since mucosal diseases impact patient's daily living and quality of life while affected by their psychological profiles, this should be considered when formulating a therapeutic approach.

Primary implant stability in the atrophic sinus floor of human cadaver maxillae: impact of residual ridge height, bone density, and implant diameter.

OBJECTIVES: Simultaneous implant placement in conjunction with lateral or transcrestal maxillary sinus floor augmentation gives the benefit of reduction in healing times and surgical interventions. Primary implant stability, however, may be significantly reduced in resorbed residual ridges. Aim of the present study was to investigate the impact of residual bone height, bone density, and implant diameter on primary stability of implants in the atrophic sinus floor. MATERIAL AND METHODS: A total of 66 NobelActive implants were inserted in the sinus floor of fresh human cadaver maxillae: 22 narrow (3.5 mm), 22 regular (4.3 mm), and 22 wide (5.0 mm) diameter implants in residual ridges of 2-6 mm height. Presurgical computed tomographic scans were acquired to assess bone height and density. Primary implant stability was evaluated by insertion torque values (ITV), Periotest values (PTV), and Osstell implant stability quotients (ISQ). RESULTS: Correlations within outcomes (ITV, PTV, ISQ) were highly significant (P < 0.001). Radiographic bone density was found to significantly impact all three outcome measures (P < 0.001), while no influence of residual bone height and implant diameter could be revealed by multifactorial analysis. Consistent results were seen in all subgroups (including residual ridges of 5-6 mm height). CONCLUSIONS: Bone density seems to represent the major determinant of primary stability in maxillary sinus augmentation with simultaneous implant placement (as well as 5-6 mm short implants in the maxillary sinus floor). Preoperative bone density assessment may help to avoid stability-related complications in one-stage implant treatment of the atrophic posterior maxilla.
