Oral adverse events associated with targeted cancer therapies.

Over the past decade, targeted therapies have emerged as promising forms of cancer treatment and are increasingly included in chemotherapeutic regimens for an ever-growing list of human cancers. Targeted therapies are so-named due to their specific targeting of dysregulated signaling pathways in cancer cells. This enhanced discrimination between tumor and normal cells is a more promising and efficacious approach to cancer treatment than conventional cytotoxic chemotherapy. However, targeted therapies still have side effects, and some manifest in the oral cavity. Oral adverse events tend to be mild and thus may be overlooked in the context of a patient's overarching diagnosis and management. These oral lesions are often noted during an intraoral examination and identified in the context of the patient's medical history and medication list. It is imperative that the dentist be informed of the oral sequelae of targeted therapies. Many of these side effects can be successfully managed in a palliative manner with conservative therapy. This article discusses the clinical presentations and treatment of intraoral adverse events attributable to the following classes of targeted therapies: epidermal growth factor receptor inhibitors, mammalian target of rapamycin inhibitors, angiogenesis inhibitors, and selected tyrosine kinase inhibitors.

The importance of the evaluation of expectations and perceptions to improve the dental service quality.

Purpose The purpose of this paper is to evaluate the use of SERVQUAL to assess service quality in Dentistry, by evaluating patients' expectations and perceptions of dental care and their association to patients' sociodemographic data. Design/methodology/approach The sample constituted of 379 subjects in the first assessment and 155 in the second phase. All employees of the companies that were clients of the dental insurance participated, a total of four companies in two states (São Paulo and Minas Gerais) of Brazil. SERVQUAL questionnaires about expectations and sociodemographic data were dispatched in the first phase, and in a second phase SERVQUAL questionnaires about perceptions. Those who had not yet received dental treatment and had agreed to participate filled out their survey in the first phase. In the second phase, the respondents had to have completed their treatment. Findings When the value gap is considered, Reliability (as a dimension) had the smallest score (-3.71). This means that it was the worst result, i.e. there is a higher difference between expectations and perceptions, and problems can be identified here. t-test confirmed that all the dimensions had some statistically significant difference with p<0.05 in relation to expectations and perceptions. Women presented higher prevalence of dissatisfaction (Tangible and Reliability dimensions), as well as the oldest participants (Empathy dimension) and those with lower parental literacy (Assurance and Empathy dimensions). The only dimension that was not significantly associated was Responsiveness. Originality/value This research suggests that the patients evaluated the physical characteristics of the premises and the interaction with the staff as the priority issues that need special attention in this service. Moreover, the use of SERVQUAL was extremely relevant for the oral health service, because it assessed the users' subjective perceptions.

Use of preventive dental care among medicaid-enrolled, school-aged US children in immigrant and nonimmigrant families: trends in Pennsylvania From 2005 through 2010.

OBJECTIVES: We describe trends in receipt of preventive dental care among Medicaid-enrolled children in Pennsylvania between 2005 and 2010, comparing the US children of immigrants with their co-ethnic peers in nonimmigrant families. METHODS: We analyzed Pennsylvania Medicaid claims, birth records, and census data for children born in Pennsylvania and enrolled in Medicaid for 10 or more months during any of the calendar years assessed. RESULTS: Receipt of preventive dental care was more likely among Latino children in immigrant families than among their peers in nonimmigrant families; also, it was more likely among White children in immigrant families than among their peers in nonimmigrant families. Rates of preventive dental care use among African American and Asian children in immigrant and nonimmigrant families were comparable. From 2005 to 2010, the percentage of Latino children in nonimmigrant families who received preventive dental care increased from 33% to 61%. Changes in other groups were significant but less dramatic. CONCLUSIONS: Receipt of preventive dental care has increased among Medicaid-enrolled children in Pennsylvania, with marked gains among Latino children. Within each racial/ethnic group, the children of immigrants were either more likely than or equally likely as children in nonimmigrant families to receive care.

Porphyromonas gingivalis, a bridge between oral health and immune evasion in gastric cancer.

Porphyromonas gingivalis (P. gingivalis) is a gram-negative oral pathogen associated with chronic periodontitis. Previous studies have linked poor oral health and periodontitis with oral cancer. Severe cases of periodontal disease can result in advanced periodontitis, leading to tissue degradation, tooth loss, and may also correlate with higher gastric cancer (GC) risk. In fact, tooth loss is associated with an elevated risk of cancer. However, the clinical evidence for this association remains inconclusive. Periodontitis is also characterized by chronic inflammation and upregulation of members of the Programmed Death 1/PD1 Ligand 1 (PD1/PDL1) axis that leads to an immunosuppressive state. Given that chronic inflammation and immunosuppression are conditions that facilitate cancer progression and carcinogenesis, we hypothesize that oral P. gingivalis and/or its virulence factors serve as a mechanistic link between oral health and gastric carcinogenesis/GC progression. We also discuss the potential impact of P. gingivalis' virulence factors (gingipains, lipopolysaccharide (LPS), and fimbriae) on inflammation and the response to immune checkpoint inhibitors in GC which are part of the current standard of care for advanced stage patients.

Orofacial manifestations of bacterial and viral infections in children.

Orofacial manifestations of bacterial and viral infections in children may cause significant discomfort and suffering. Recognition of the clinical presentation of these disorders is paramount to their clinical management and appropriate referral.

Dental Management of the Human Papilloma Virus-Related Oropharyngeal Cancer Patient.

Human papilloma virus (HPV)-attributable head and neck cancers (HNCs) are on the rise, impacting younger patients compared with HPV (-) HNC. Fortunately, HPV (+) HNCs are associated with favorable prognoses and tend to be radiosensitive. However, radiation therapy for the treatment of HNC is associated with acute and chronic normal tissue toxicity to salivary glands, muscles, bone, and the oral cavity and presents a treatment challenge. Thus, the prevention of normal tissue injury and optimization of oral health are key. Dental teams are important members of the multidisciplinary cancer team.

The Patient Faints in the Waiting Area with a Suspected Hypoglycemic Event.

An older adult with diabetes is taking glipizide, a sulfonylurea class drug. Subsequently, she experiences a hypoglycemic episode in the dental office. Prompt recognition of hypoglycemia and administration of glucose or sugar is vital. Patient and provider education about the risks of hypoglycemia in older adults may help to prevent future hypoglycemic episodes.

An Elderly Patient with Undiagnosed Type 2 Diabetes Mellitus Presenting for an Emergency Extraction.

In this case a patient has multiple risk factors for diabetes including periodontal disease, family history positive for diabetes, and body mass index of 24 in an Asian American. He has no medical or dental home and upon presenting to the dental office would be a good candidate for diabetes screening.

A Diabetic Patient with a Recent History of Flap and Osseous Surgery Presents Back with Bleeding and Infection.

A patient with type II diabetes and renal disease developed infection and bleeding after periodontal osseous surgery. The clinician did not adequately assess the patient's long-term glycemic status or stage of chronic kidney disease (CKD) before initiating osseous surgery. Preoperative assessment of patients with diabetes should include at a minimum an Hba1c within 3 months and estimated glomerular filtration rate for CKD.

Patient with Type I Diabetes Mellitus Develops Post-Operative Hyperglycemia After Osseous Surgery.

A patient with type I diabetes withheld her diabetes medications without consulting her physician and was not able to resume her normal diet after extensive dental surgery resulting in hyperglycemia postoperatively. Clear communication between clinicians and patient about the expected postoperative course and changes to factors that may influence glycemic control could prevent hyperglycemia in the postoperative period.

A Patient with Refractory Trigeminal Neuralgia was Referred for Suspected Odontogenic Pain.

Chronic pain of the face with a sudden, unilateral, and electric shock-like pain in the distribution of the trigeminal nerve is known as Trigeminal neuralgia (TN). This case report presents a patient with TN symptoms, along with concomitant tooth pain. The diagnostic process and management of the patient are discussed, emphasizing the importance of interdisciplinary collaboration for optimal patient care.

A Pregnant Patient with Gestational Diabetes Reports for Scaling and Root Planning.

In this case a woman with gestational diabetes and otherwise healthy pregnancy needs scaling and root planning for the treatment of stage I periodontal disease during pregnancy. Her daily blood sugars are in the target range, and there are no contraindications to providing necessary dental treatment under local anesthesia with vasoconstrictors in her case.

An Adolescent Patient Reports to Dental Office for Pain in Relation to Mandibular Molar with an Incidental Palpable Thrill in the Submandibular Region.

A young female patient presents to a dental clinic for treatment of swelling and pain. Clinical examination and testing are completed revealing concomitant, suspected vascular pathology of the head and neck area. An endodontic diagnosis is made, but an unusual clinical finding of a vascular entity, not typically considered by dentists, requires interdisciplinary assessment and management with vascular surgery before surgical intervention of the oral cavity.

Oral factitious injury in a child diagnosed with Kabuki syndrome.

Factitious injury or self-injurious behavior is a common manifestation in children affected by neurologic, developmental, or psychiatric disease. The nature and presentation of this behavior in the oral cavity varies among diagnoses, and such behavior can be easily missed. This report describes the presence of self-injurious behavior in a child diagnosed with Kabuki syndrome who presented to a pediatric dentistry referral practice for evaluation of gingival bleeding, and provides a brief overview of the known etiology and management of this challenging condition. Clinicians should be aware of the possibility of self-injurious behavior when treating children diagnosed with Kabuki syndrome.

A survey of senior dental students' experiences with young dental patients in Pennsylvania.

The purpose of this study was to determine graduating dental students' perceptions about their training and experience in examination and treatment of infants and their plans to examine infants upon graduation. A survey was distributed to dental students graduating from Pennsylvania dental schools in 2007 and 2008. Of the returned surveys, 47.9 percent correctly identified 12 months as the recommended age for the first dental exam. Sixty-five percent of responders felt they would be comfortable performing exams on young children. This study's primary objective was to test the association between performance of a clinical exam in a young child, enjoyment of clinical and didactic pediatric dental experience, plans for additional training in pediatric dentistry and willingness to see children younger than two years old in practice. Performing a clinical exam on a young child was associated to willingness to see children younger than two years of age in practice. Early exposure (lecture or clinical) to young pediatric patients while in dental school was significantly associated to perceived comfort with oral exam of young patients but not to reported willingness to see them in practice.

Analysis of clinical oral medicine practices at the University of Pennsylvania: a 5-year retrospective study.

OBJECTIVE: The aim of this study was to characterize oral medicine (OM) clinical practices at the University of Pennsylvania (Penn), determine the importance of OM clinical services, and emphasize aspects of training for OM specialists. STUDY DESIGN: Nonprobability sampling of OM resident patient logs for patients receiving clinical care from 2008 to 2013 was conducted. OM resident patient logs included clinical diagnosis, International Classification of Diseases, ninth edition code, medical history, clinical procedure, Current Procedural Terminology code, attending physician, and resident participation notes. RESULTS: Outpatients in OM medical practices (n = 6024) averaged 1.56 diagnoses from OM specialists. Orofacial pain (45.02%) and oral mucosal diseases (34.28%) comprised the majority of OM diagnoses. The most common procedures were tissue biopsies (59.34%) and treatments for temporomandibular disorders (29.9%). Inpatients (n = 313) comprised 3.46% of Penn OM hospital services, and cardiovascular disorders (38.99%) were the most common admitting diagnoses in this group. In the OM dental practice (n = 1648), 42.05% of patients had a median of 3 medical comorbidities (range = 2-11), of which cardiovascular disorders (27.13%) were most prevalent. CONCLUSIONS: Analysis of Penn OM clinical practices emphasizes the breadth and multidisciplinary nature of OM services and importance of comprehensive postdoctoral training in all domains of OM.

Headache in children and adolescents.

The broad field of orofacial pain encompasses pain conditions affecting the head, face, neck and intraoral structures. Much has been written about headache specifically affecting adults, but little is known about the presentation of this problem in children. Dentists may be asked to participate in the differential diagnosis or management of headache in young patients. For their benefit, this article discusses the epidemiology, clinical presentation, diagnosis and treatment of headache in this population. An accurate history and careful examination can allow early diagnosis and the avoidance of unnecessary or inappropriate dental procedures.

Prescribing NSAIDs to patients on SSRIs: possible adverse drug interaction of importance to dental practitioners.

Abstract: The potential for adverse drug interactions is a growing concern for dental practitioners. Recent studies report an increased risk of gastrointestinal (GI) bleeding when nonsteroidal antiinflammatory drugs (NSAIDs) are taken concomitantly with selective serotonin reuptake inhibitors (SSRIs) than when either class of drugs is taken alone. A PubMed structured search was performed for published English language literature analyzing the epidemiology of this interaction between January 1, 1997 and December 31, 2007. Four cohort and five case-control studies were included in the final selection. Most studies show an increased risk for developing GI bleeding with concurrent use of SSRIs and NSAIDs, reporting an odds ratio between 1.8 and 15.6. Seven studies were done on adult European Caucasian populations, one in Canada, and one in the United States, with follow-up data collected ranging from 6 months to 13 years. The primary limitation was the variation in methodology, inclusion criteria, comparison groups, and statistical analyses. A significant correlation between the combination of these drugs and GI bleeding has been reported in retrospective studies. Nonetheless, a causal inference cannot be made based on the available evidence and the lack of randomized controlled clinical trials.

Review of obesity and periodontitis: an epidemiological view.

Obesity and periodontitis are among the most common non-communicable diseases, and epidemiological studies report the influence of obesity in the onset and progression of periodontitis. Data indicate that increased body mass index, waist circumference, percentage of subcutaneous body fat, and serum lipid levels are associated with increased risk to develop periodontitis. The underlying biological mechanisms of this association involve adipose tissue-derived cytokines, such as tumour necrosis factor-α and interleukin-6, which affect whole-body metabolism and contribute to the development of a low-grade systemic inflammation. Multiple studies report a positive association between these two diseases across diverse populations. Obesity does not appear to impair the success of periodontal therapy. However, currently available evidence is variable and therefore inconclusive. Despite the limited evidence about recommendations on treatment planning, oral healthcare professionals need to be aware of the complexity of obesity to counsel their patients about the importance of maintaining healthy body weight and performing good oral hygiene procedures.

Risk factors for caries development in primary Sjogren syndrome.

OBJECTIVES: The aim of this study was to compare the risk factors for caries between patients with primary Sjogren syndrome (SS) and those with non-Sjogren syndrome (NSS) salivary hypofunction and to identify the prevalence of incisal or cervical/root caries in each group. STUDY DESIGN: This was a retrospective, cross-sectional study conducted at a single center between 2012 and 2015 for assessment of patients with possible SS. Two-hundred and twenty-five (225) patients (99 SS and 126 NSS) participated in the study. RESULTS: Student t test and Wilcoxon's rank sum test were used to evaluate group differences in continuous variables and the χ2 test was used to determined differences in categorical variables. Significant univariate associations were further assessed by using multivariate ordinal regression models. Patients with SS were more likely to have a greater number of total caries (odds ratio [OR] 1.72 [1.03-2.88]; P = .04). And a focus score greater than 1/4 mm2 was associated with greater number of total caries (OR 2.88 [1.05, 7.93]; P = .04]. Adjusted analysis for salivary flow did not show a significant association between stimulated or unstimulated salivary flow or glandular-specific salivary flow and the total number of carious lesions. CONCLUSIONS: Patients with salivary hypofunction secondary to SS do have a greater caries risk compared with patients with salivary hypofunction caused by other factors. In this study cohort, this finding was not associated with salivary flow rates.
