Assessment of palatal mucosal thickness and location of the greater palatine foramen using cone-beam computed tomography: a retrospective study.

OBJECTIVES: This study aimed to measure the palatal mucosal thickness and examine the location of the greater palatine foramen using cone-beam computerized tomography (CBCT). METHODS: In this study, cone-beam computed tomography (CBCT) images of the maxillary posterior region of 120 subjects were evaluated. The palatal mucosal thickness (PMT), palatal width and depth, and location of the greater palatine foramen (GPF) were determined on CBCT. The differences in the palatal mucosal thickness according to gender and palatal width/palatal depth were analyzed. The location of the GPF related to the maxillary molars was noted. RESULTS: The mean palatal mucosal thicknesses from the canine to the second molar teeth were 3.66, 3.90, 4.06, 3.76, and 3.92 mm, respectively. The mean PMT at the second premolar was statistically thicker than at other regions (p < 0,001). There was no relationship between PMT and gender. However, the palatal depth and width of the males were greater than females. (p = 0.004 and p = 0.014, respectively) PMT in the low palatal vault group had statistically higher compared to the high palatal vault group. (p = 0.023) Greater palatine foramen was mostly observed between second and third molar teeth. (48%). CONCLUSIONS: According to our results, first and second premolar regions can be preferable in soft tissue grafting procedures for safe and successful treatment outcomes. The measurement of the thickness of the palatal mucosa and the evaluation of the greater palatine foramen location before the surgical procedures are essential steps to harvest from the ideal donor site and to achieve optimal surgical outcomes.

Assessment of gingival thickness in the maxillary anterior region using different techniques.

OBJECTIVES: Gingival phenotype is closely related to treatment success and aesthetic results in the maxillary anterior region. Several methods were proposed to measure the dimensions of the gingival tissue. This study aimed to evaluate the gingival thickness using clinical and radiographic techniques and to explore the association between gingival thickness and gingival phenotypes classified by color-coded phenotype probes. MATERIALS AND METHODS: The gingival thickness of 86 periodontally healthy maxillary anterior teeth was assessed using transgingival probing (TGP) and cone-beam computed tomography (CBCT). The gingival phenotype was classified as thin, medium, thick, or very thick by transparency of the color-coded probes through the gingival sulcus. The labial alveolar bone thickness was measured on CBCT images. The keratinized tissue width (KTW) was recorded. RESULTS: Good to excellent agreement was found between TGP and CBCT regarding the thickness of the gingiva (p<0.001). There was a very high correlation between the phenotypes determined by color-coded probes and the gingival thickness measured by TGP (r=0.953, p<0.001). KTW was significantly higher in thick and very thick phenotype groups compared with thin phenotype group. CONCLUSION: Cone-beam computed tomography images and the probe transparency method with color-coded probes are reliable for identifying the gingival phenotype in the maxillary anterior region, based on comparisons to direct transgingival probing. CLINICAL RELEVANCE: The assessment of the gingival phenotype is essential, especially in the aesthetic zone, to obtain predictable and favorable clinical outcomes in various dental procedures. The newly introduced color-coded probes comprise a non-invasive and reliable method for this.

Impact of stage-grade of periodontitis and self-reported symptoms on oral health-related quality of life.

OBJECTIVES: The aim of the study was to investigate the impact of stage-grade of periodontitis and self-reported signs and symptoms on oral health-related quality of life. METHODS: The diagnosis of periodontitis was based on the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions. The Turkish version of Oral Health Impact Profile-14 (OHIP-14) was used to assess oral health-related quality of life (OHRQoL) and the participants were requested to state their symptoms associated with periodontal diseases. RESULTS: One hundred and sixty-six patients were included in the study with a mean age of 46.54 ± 9.24 years. The participants with Stage IV and Grade C periodontitis had the highest total OHIP-14 scores (median 20.00 [min.-max, 3.00-35.00] and median 18.50 (min.-max, 0.00-36.00]; respectively). The OHIP-14 scores (mean ± SD) were significantly associated with the symptoms of bleeding gums (13.64 ± 9.39), sore gums (18.00 ± 10.47), swollen gums (17.42 ± 10.91), bad breath (15.82 ± 9.44), loose teeth (20.00 ± 8.66) and drifting teeth (24.56 ± 8.46). CONCLUSIONS: This study demonstrates a significant association between OHRQoL and periodontitis. Stage-grade of periodontitis and its symptoms were associated with poor quality of life.

Prevalence of Carotid Artery Calcification on Digital Panoramic Radiographs in Hemodialysis Patients on Kidney Transplant Waiting List.

OBJECTIVES: The detection of carotid artery calcification at an early stage is important to reduce the effects of cardiovascular disease in patients undergoing hemodialysis. This study sought to evaluate the prevalence of carotid artery calcification from panoramic radiographs of patients who were undergoing hemodialysis and to assess the relationship between such calcification and certain medical and periodontal parameters. MATERIALS AND METHODS: We evaluated 120 panoramic radiographs from patients who were undergoing hemodialysis for the presence of carotid artery calcification. Full-mouth periodontal clinical and medical parameters were recorded, and patients were diagnosed on the basis of the new periodontal disease classification. Patient medical records from the same period (the same week) during which the panoramic radiographs were taken were also assessed. RESULTS: Among the 120 participating patients, pano - ramic radiographs from 27 patients (22.5%) showed a uni- or bilaterally radiopaque mass. Of the periodontal clinical parameters investigated for associations between patients with and without carotid artery calcification, there was only a significant difference shown for probing pocket depth (P = .017). No significant differences were found between the groups with and without carotid artery calcification with regard to any other medical or periodontal parameter. CONCLUSIONS: In our study group, suspected carotid artery calcifications were detected on panoramic radiographs in about one-fourth of total patients receiving hemodialysis. Because of the significant relationship found between probing pocket depth and carotid artery calcification, the presence of periodontal disease may be associated with calcifications in these patients. Dentists should maintain awareness in detecting these lesions when evaluating panoramic radiographs of patients undergoing hemodialysis.

Assessment of carotid artery calcifications on digital panoramic radiographs and their relationship with periodontal condition and cardiovascular risk factors.

OBJECTIVE: The main purpose of this study is to determine the presence of carotid artery calcification (CAC) detected on digital panoramic radiographs (DPRs) retrospectively and correlate the findings with cardiovascular risk factors including gender, age, smoking status, hypertension, diabetes, and hyperlipidemia, along with atherosclerotic cardiovascular disease and periodontal status. METHODS: This clinical study is registered at ClinicalTrials.gov as NCT04017078. DPRs, periodontal status and cardiovascular risk factors of 1,101 patients (576 males, 525 females) were evaluated. The patients were grouped based on whether CAC was detected in dental DPRs [CAC (+)] or not [CAC (-)]. Periodontal status was categorised as gingivitis, periodontitis, and gingivitis with reduced periodontium (periodontally stable patient). RESULTS: Out of 1,101 patients, whose mean age was 42.1 ± 15.5 years and 525 (47.7%) were female, 34 (3.1%) were diagnosed with CAC on DPRs. No significant difference was observed between groups considering gender, hypertension, diabetes, hyperlipidemia, smoking, and periodontal status. Patients aged 40-55 years (n = 398, 36.15%) and patients older than 55 years (n = 222, 20.16%) were associated with CAC (odds ratio = 4.49, 95% confidence interval = 1.65-12.17, P = 0.003; odds ratio = 4.41, 95% confidence interval = 1.33-14.61, P = 0.015, respectively). CONCLUSION: Among all parameters, only age exhibited significant correlation with an increased risk of carotid calcification. Further studies with prospective designs and larger study populations are needed.

Evaluation of patients' perception of gingival recession, its impact on oral health-related quality of life, and acceptance of treatment plan.

Objective: Gingival recessions (GR) may cause aesthetic and hypersensitivity complaints which might affect oral health-related quality of life (OHRQoL). The aim of this study was to evaluate the patients' awareness of their own GR, the impact of GR on OHRQoL and the acceptance of suggested treatment modalities.Materials and Methods: This cross-sectional study was conducted with 205 patients. The demographic variables were recorded and patients' perception of GR was questioned. Full-mouth examination was carried out and clinical parameters were recorded. Gingival recessions, GR related complaints were evaluated and GR treatments were suggested and acceptance were also recorded by the examiner. The patients filled out OHRQoL-United Kingdom (OHRQoL-UK) questionnaire regarding to their GR and were asked if GR have/would have impact on oral health and if the GR will/would get worsen. Data was analysed with independent t test and Mann-Whitney U test.Results: 4819 teeth were evaluated and 733 GR examined in 147 patients. Fifty-seven patients were unaware of their GR. A strong belief that GR have impact on oral health (88.78%) and GR will progress (86.34%) was detected. Acceptance of treatment was increased and non-invasive modalities were preferred if patients had complaints. The awareness of GR status increases and the misperception decreases the OHRQoL-UK scores. The results revealed that hypersensitivity decreases the OHRQoL-UK scores and aesthetic concerns and hypersensitivity decreases the OHRQoL-UK physical scores significantly (p < .05).Conclusions: The results indicated that the patients might be unaware of their GR and the GR related factors may lead to poorer OHRQoL.
