Foreign body reactions related to orofacial esthetic fillers: A systematic review.

The aim of this study was to systematically review the clinicopathological data regarding foreign body reactions (FBR) related to esthetic procedures in the orofacial region. Electronic searches were performed in six databases and in gray literature using PEO acronym for the review question. Case series and case reports describing FBR related to esthetic procedures in the orofacial region were included. The JBI Critical Appraisal Checklist-University of Adelaide tool was used for measuring the risk of bias. Eighty-six studies reporting 139 cases of FBR were identified. The mean age at diagnosis was 54.12 years (14-85 years), with most of the cases reported in America, North America (n = 42/30.70%) and Latin America (n = 33/23.60%), mainly occurring in women (n = 131/94.40%). Asymptomatic (n = 60/43.40%) nodules (n = 71/50.60%) were the main clinical characteristics. The lower lip represented the most affected anatomical location (n = 28/22.20%), followed by the upper lip (n = 27/21.60%). Surgical removal was the treatment of choice (n = 53/35.70%). Twelve different dermal fillers were reported in the study, and the microscopic characteristics of the cases varied according to the material used. The results based on case series and case reports showed that nodule and swelling were the main clinical characteristics of FBR related to orofacial esthetic fillers. The histological characteristics depended on the type of the filler material used.

Association between tamoxifen and tooth loss in women with breast cancer.

OBJECTIVES: Investigate the effect of tamoxifen on the occurrence of tooth loss (TL) in breast cancer (BC) survivors. METHODS: A cross-sectional study was conducted with 140 BC survivors using tamoxifen therapy. Sociodemographic, medical, and dental data were evaluated. TL was determined using the M component of the Decayed, Missing and Filled Teeth (DMFT) index. Logistic regression models were run to determine associations between the independent variables and outcome (TL). RESULTS: Mean TL was 12.96 (SD 8.88). Only three participants had lost no teeth and 10.7% were completely edentulous. Participants who used tamoxifen for more than 1 year had a higher mean missing teeth (13.99 vs. 10.45; P = 0.030). After the adjustments, the occurrence of more than 12 missing teeth was 2.75-fold higher among women who used tamoxifen for more than 1 year (95% CI: 1.06-7.12). Moreover, age over 65 years, referral for treatment by the public healthcare system, less use of dental services, xerostomia, and a lower occurrence of dental caries remained associated with the loss of more than 12 teeth. CONCLUSION: Longer use of tamoxifen was associated with greater tooth loss in breast cancer survivors. CLINICAL RELEVANCE: Based on estimates of the increase in cases of breast cancer, the prolonged use of tamoxifen for the treatment of this disease can exert an impact on oral health through the occurrence of tooth loss. These findings can contribute to the planning and implementation of oral health care and prevention strategies for such patients.

Oral health-related quality of life in breast cancer survivors.

OBJECTIVE: The aim of the present study was to evaluate oral health-related quality of life (OHRQoL) among breast cancer survivors and identify possible factors associated with the outcome. METHODS: A cross-sectional study was conducted with 151 women in follow-up at a hospital after treatment for breast cancer. Data were collected on socio-demographic characteristics, general health, and breast cancer. Clinical examinations were performed to determine caries experience using the decayed, missing, and filled teeth (DMFT) index. The Oral Health Impact Profile (OHIP-14) questionnaire was administered for the assessment of OHRQoL. Logistic regression analysis was performed to identify associated factors after adjustments for confounding variables. RESULTS: The mean OHIP-14 score was 12.8 (SD 10.92). The prevalence of negative impact was 58.9%. A negative impact was associated with depression, the diagnosis of breast cancer, chemotherapy, number of restored teeth, and xerostomia (p < 0.05). In the adjusted analysis, only the oral variables remained significantly associated with the outcome. CONCLUSION: A greater number of restored teeth and xerostomia exert a negative impact on the OHRQoL of women who have survived breast cancer, which suggests the need for special attention to the oral health of this population.

Virtual learning object about oral ulcerative lesions: controlled educational intervention study.

The aim of this study was to develop a virtual learning object (VLO) to teach undergraduate dental students about the diagnostic and therapeutic approaches to oral ulcerative lesions. The VLO was developed with information on the diagnostic process, lesion classification, and clinical-surgical management of oral ulcerative lesions. The VLO content was initially validated by a group of specialists. Learning was evaluated in a sample of 58 undergraduate dental students, divided into control group (conventional theoretical class, n = 29) and intervention group (interaction with VLO, n = 29). All students answered a pre-test and post-test questionnaire. The VLO group also answered a specific questionnaire on the evaluation of the VLO. Both quantitative and qualitative descriptive analyses were performed. The validation showed that professors and students considered the VLO adequate. The use of the VLO was recommended by 100% of professors and 86.6% of students. In the intervention group, the results showed a significantly higher number of correct answers in the post-test (p < 0.01). In conclusion, the VLO proved to be a useful tool for teaching oral medicine, contributing significantly to the knowledge of ulcerated lesions in the mouth.

Prognostic factors from squamous cell carcinoma of the hard palate, gingiva and upper alveolar ridge.

The purpose of this study was to evaluate the clinicodemographic characteristics and treatment protocol as prognostic factors in patients with oral squamous cell carcinoma (OSCC) of the hard palate, upper gingiva, and alveolar ridge (HPUGAR). This retrospective cohort study collected data of patients treated in two head and neck surgery departments in southern Brazil between 1999 and 2021. Information on clinicodemographic data, habits, site, size, clinical aspect, clinical staging, cervical metastasis, treatment, and survival was collected. Associations between independent variables and outcomes were assessed using Pearson's chi-square test and binary regression. Kaplan-Meier test was employed to compare the survival between the neck approaches. Forty-one patients were included; most were male (61%), with a mean age of 68.8 (± 13.9) years. The consumption of tobacco (p = 0.003) and alcohol (p = 0.02) was significantly higher in male than in female patients. The main clinical features observed in the study sample were lesions larger than 2 cm (48.7%), no cervical (90.2%), or distant metastasis (90.2%). Surgery alone was the main treatment approach (48.8%). The watch-and-wait strategy was adopted in 34 cases (83.0%), while elective neck dissection was applied in five (12.2%). Only two patients with cN0 disease (4.9%) presented with cervical metastasis at follow-up. Eight patients (12.2%) died of the disease. Clinicodemographic variables, habits, surgical margins, and histological subtype were not significantly associated with cervical metastasis or survival. Cervical metastasis (p = 0.004) was associated with poor survival. No difference was detected in survival between different neck approaches (p = 0.28). Cervical metastasis and local recurrence are negative prognostic factors for HPUGAR OSCC.

Analysis of factors that influence quality of life of individuals undergoing treatment for mandibular fractures: A systematic review and meta-analysis.

OBJECTIVE: To address the factors that affect the quality of life (QoL) of individuals undergoing treatment for mandibular fractures. STUDY DESIGN: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the search strategy was constructed according to the Populations, Interventions, Comparison, Outcomes, and Study Design principle in the following databases: PubMed, Web of Science, Scopus, and EMBASE. Risk of bias assessment was performed with Risk Of Bias In Non-randomized Studies of Interventions and Cochrane Risk of Bias tool for randomized trials 2. RESULTS: Nineteen studies were included: 15 observational and 4 clinical trials. Mean age ranged from 28 to 39 years, with a higher proportion of males. The condyle was the main fracture location and traffic accident was the fracture cause. Treatment approaches were mostly open reduction (89.4%) and maxillomandibular fixation (63%). QoL measurements varied considerably with the General Oral Health Assessment Index (31.5%) and Oral Health Impact Profile-14 (21%) as the main instruments. Meta-analysis showed that open reduction and maxillomandibular fixation did not present significant differences to QoL (P = .39), but significant differences were observed with time (P < .00001). Other factors affected QoL, such as mental health, pain, socializing, appearance, and eating difficulties. CONCLUSIONS: Several factors, apart from the treatment approach, mentioned in this review seemed to affect the QoL of patients with mandibular trauma. Treatment choice should be based on well-stablished clinical criteria and on all other factors mentioned here.

Effects of osteoporosis on alveolar bone repair after tooth extraction: A systematic review of preclinical studies.

OBJECTIVE: This systematic review aimed to address whether the alveolar socket repair after a tooth extraction is impacted by an osteoporotic phenotype and propose methodological observations. DESIGN: A search strategy in MEDLINE/PubMed, EMBASE, Web of Science, and Scopus databases was performed. Quality assessment was carried out through the SYRCLE Risk of Bias tool. RESULTS: Out of the 1147 potentially relevant records, 25 met the inclusion criteria. Most of the studies were performed in rats, and ovariectomy (OVX) was the most frequent osteoporosis induction method. Histomorphometry, micro-computed tomography (microCT), and immunohistochemistry were the main bone repair evaluation methods. Most of the included studies (88 %) presented negative impacts of osteoporosis on the alveolar socket repair. Only three studies (12 %) showed no statistical differences among groups. Overall, most of the quality assessment categories presented a high percentage of unclear risk of bias due to insufficient information in the studies. CONCLUSIONS: The results indicated that an osteoporotic phenotype seems to impair alveolar socket repair after tooth extraction. However, there is still a lack of information and standardization. Therefore, further studies should consider the proposed methodological aspects regarding animal characteristics, OVX associated with a low calcium diet, waiting 8 weeks to osteoporosis induction, maxillary molars as the best option for tooth extraction, confirming and reporting OVX and osteoporosis success, and an appropriate method of repair analysis.

Oral lesions and associated factors in breast cancer survivors.

AIM: To evaluate the prevalence of oral lesions (OL) and associated factors among survivors of breast cancer (BC). METHODS: A cross-sectional study involving 150 BC survivors was conducted at a public hospital in southern Brazil. Data were collected on socioeconomic aspects, treatment characteristics and oral problems. The decayed, missing and filled teeth index and the occurrence of OL were evaluated. Logistic regression was performed to determine independent variables associated with the outcome. RESULTS: 24% of the women had at least 1 OL and 33.3% of these had more than one lesion. Melanotic macule was the most prevalent lesion. Duration of tamoxifen use, radiotherapy, missing teeth and xerostomia were associated with the occurrence of OL (P < .05). In the adjusted analysis, women with more than 13 missing teeth and xerostomia had 2.39-fold (95% confidence interval [CI], 1.06-5.40) and 2.71-fold (95% CI, 1.14-6.42), respectively, greater odds of exhibiting OL. CONCLUSION: Approximately 1/4 of the BC survivors exhibited OL, which were associated with tooth loss and xerostomia. These findings could assist in the establishment of oral health strategies for women with BC.
