Efficacy of natural enzymes mouthwash: a randomised controlled trial.

OBJECTIVES: Natural enzymes mouthwash has been proposed as salivary substitutes to treat xerostomia. This study aims to evaluate the efficacy of the mouthwash to treat xerostomia. MATERIALS AND METHODS: A double-blind, parallel group randomised control clinical trial involving N = 49 adult participants with xerostomia was carried out. Intervention group received natural enzymes moisturising mouthwash (with active ingredients lactoferrin, lysozyme, lactoperoxidase and glucose oxidase); while control group received benzydamine mouthwash. Mouthwashes were repacked, labelled with specific code, and were given to participants by third-party. Subjects were instructed to rinse with the mouthwash 4 times per day at a specific period, for 2 weeks. Symptoms of xerostomia were assessed using Xerostomia Inventory at day 0 and 14; together with the assessment of Clinical Oral Dryness Score (CODS), and measurement of resting and stimulated salivary flow rate. RESULTS: 48 participants completed the clinical follow-up, and n = 1 had lost of follow-up. From the 48 participants, n = 23 received natural enzymes mouthwash, while n = 25 received benzydamine mouthwash. Intervention group achieved reduction in symptoms of xerostomia from baseline. Intervention group also showed significantly better improvements in the cognitive perception of dry mouth and oromotor function such as chewing, swallowing and speech of the participants; and reduction in waking up at night to drink water (p < 0.05). The CODS and resting salivary flow rate were also significantly improved in intervention group (p < 0.05). CONCLUSION: Use of natural enzymes mouthwash improved signs and symptoms of xerostomia. CLINICAL RELEVANCE: Natural enzymes mouthwash is potentially effective to treat xerostomia, well-tolerated and safe to be used by xerostomia patients. CLINICAL TRIAL REGISTRATION NUMBER: This study was retrospectively registered in ClinicalTrials.gov ID NCT05640362 on 7 December 2022.

Management of Bimaxillary Protrusion.

Bimaxillary protrusion is a unique dentofacial deformity trait that can exist in an individual as an isolated problem or in combination with other skeletal and dental-related issues. Orthodontist and oral and maxillofacial surgeons are often the main primary team involved in the management of bimaxillary protrusion. Clinical dilemma often exists as cases can either be treated orthodontically or may require a combination of orthodontic and skeletal segmental orthognathic surgery. This article aims to help clinicians improve their approach to management of bimaxillary protrusion by creating a classification based on the severity that can guide treatment selection.

Posttraumatic Growth, Positive Psychology, Perceived Spousal Support, and Psychological Complications in Head and Neck Cancer: Evaluating Their Association in a Longitudinal Study.

Despite head and neck cancer (HNC) association with various negative impacts, collective evidence is accumulating regarding the positive impacts of positive psychology on cancer survivors. However, data on how positive psychology is related to the psychological complications of HNC across time are lacking. This longitudinal study examined the trends of positive psychology (e.g., posttraumatic growth [PTG], hope, and optimism), perceived spousal support, and psychological complications (e.g., depression, anxiety, and posttraumatic stress symptoms) and determined the association between them, psychological complications, and PTG across two timelines among a cohort of HNC patients. A total of 175 HNC respondents exhibited an increasing trend of positive psychology and perceived spousal support while reporting a decreasing trend of psychological complications between baseline and follow-up assessments. A greater degree of hope and perceived spousal support contributed to a higher degree of PTG across time. Conversely, a higher severity of anxiety symptoms was associated with a lower degree of PTG over time. Female gender had a moderating effect on the association between severity of anxiety symptoms and PTG, but did not moderate the association between hope, perceived spousal support and PTG. This study indicates the pivotal role of incorporating psychosocial interventions into the treatment regimen to enhance the degree of hope and perceived spousal support and reduce the severity of anxiety symptoms, which, in turn, will facilitate the development of PTG in HNC patients.

Posttraumatic growth and its association with unmet supportive care needs and fear of cancer progression among head and neck cancer patients.

BACKGROUND AND AIMS: The assessment of supportive care needs and fear of cancer progression are important variables to be considered when evaluating the psychological aspects of cancer patients. However, data on how these variables affect posttraumatic growth (PTG) are lacking. This study aimed to investigate the level of PTG among head and neck cancer (HNC) patients within the first year of cancer diagnosis and to determine the association between unmet supportive care needs, fear of cancer progression, and the level of PTG. METHODS: Participants were administered socio-demographic and clinical characteristics questionnaire; the 34-item Supportive Care Needs Survey (SCNS-34) to measure the unmet needs; 12-item Fear of Progression Questionnaire-Short Form (FoP-Q-SF) to measure the fear of progression of cancer; and the Posttraumatic Growth Inventory-Short Form (PTGI-SF) to measure the degree of PTG. RESULTS: A total of 190 HNC participants reported a mean total PTGI-SF score of 39.3 (standard deviation = 9.5). General linear model revealed that higher degree of patients' physical and daily living unmet needs and fear of cancer progression significantly predicted lower PTG, after controlling for sociodemographic and clinical factors. CONCLUSION: HNC patients within the first year of cancer diagnosis reported a high level of PTG. Despite that, psychosocial intervention for HNC patients should emphasize on counteracting patients' physical and daily living unmet needs and fear of cancer progression to improve the psychological well-being of patients.

Posttraumatic Growth and Coping Strategies Among Patients With Head and Neck Cancer: Do Approach Coping and Avoidant Coping Predict Posttraumatic Growth Over Time?

Despite an enormous number of studies addressing the importance of posttraumatic growth (PTG) among cancer patients, the literature lacks data regarding how different coping strategies affect PTG among head and neck cancer (HNC) patients over time. This longitudinal study investigated the PTG trend and coping over 5-7months among a cohort of HNC patients within the first year after their diagnosis. It determined an association between coping strategies and PTG over time. The study's HNC respondents were administered a socio-demographic and clinical characteristics questionnaire during their baseline assessments. Additionally, the Malay versions of the "PTG Inventory-Short Form" (PTGI-SF) and the "Brief Coping Orientation to Problems Experienced Inventory" (Brief COPE) were administered during respondents' baseline assessments and follow-up assessments (5-7months after the baseline assessments). In total, 200 respondents reported an increasing PTG trend and approach coping (active coping, planning, positive reframing, acceptance, emotional support, and instrumental support) and a decreasing trend of avoidant coping (self-distraction and denial) over time. Two approach coping strategies (acceptance and planning) significantly increased PTG while denial was the only avoidant coping strategy that significantly lowered PTG, after controlling for socio-demographic and clinical characteristics, over time. Our study's findings identified the need to incorporate psychosocial interventions that enhance approach coping and reduce avoidant coping into HNC patients' treatment regimes.

Intraoperative Computed Tomography Scan for Orbital Fracture Reconstruction.

Orbital fractures pose specific challenge in its surgical management. One of the greatest challenges is to obtain satisfactory reconstruction by correct positioning of orbital implant. Intraoperative computed tomography (CT) scan may facilitate this procedure. The aim of this study was to describe the early use of intraoperative CT in orbital fractures repair in our center. The authors assessed the revision types and rates that have occurred with this technique. With the use of pre-surgical planning, optical intraoperative navigation, and intraoperative CT, the impact of intraoperative CT on the management of 5 cases involving a total number of 14 orbital wall fractures were described. There were 6 pure orbital blowout wall fractures reconstructed, involving both medial and inferior wall of the orbit fracturing the transition zone and 8 impure orbital wall fractures in orbitozygomaticomaxillary complex fracture. 4 patients underwent primary and 1 had delayed orbital reconstruction. Intraoperative CT resulted in intraoperative orbital implant revision, following final navigation planning position, in 40% (2/5) of patients or 14% (2/14) of the fractures. In revised cases, both implant repositioning was conducted at posterior ledge of orbit. Intraoperative CT confirmed true to original reconstruction of medial wall, inferior wall and transition zone of the orbit. Two selected cases were illustrated. In conclusion, intraoperative CT allows real-time assessment of fracture reduction and immediate orbital implant revision, especially at posterior ledge. As a result, no postoperative imaging was indicated in any of the patients. Long-term follow-ups for orbital fracture patients managed with intraoperative CT is suggested.

Prevalence of oral cancer, oral potentially malignant disorders and other oral mucosal lesions in Cambodia.

OBJECTIVES: To obtain data on the prevalence of oral mucosal lesions (OMLs) among Cambodians, and to assess the relationship between known risk habits of oral diseases with prevalence of oral potentially malignant disorders (OPMDs). DESIGN: This was a population-based, cross-sectional study whereby subjects were adults aged 18 years old and above. A workshop on the identification of OML was held to train and calibrate dental officers prior to data collection in the field. Sociodemographic and risk habits data were collected via face-to-face interview, whilst presence of OML and clinical details of lesions such as type and site were collected following clinical oral examination by the examiners. Data analysis was carried out using the Statistical Package for Social Science (SPSS) version 12.0. The association between risk habits and risk of OPMD was explored using logistic regression analysis. RESULTS: A total of 1634 subjects were recruited. Prevalence of OML for this population was 54.1%. Linea alba was the most common lesion seen (28.7%). This study showed an overall OPMD prevalence of 5.6%. The most common type of OPMD was leukoplakia (64.8%), followed by lichen planus (30.8%). Subjects who only smoked were found to have an increased risk for OPMD of almost four-fold (RR 3.74, 95%CI 1.89-7.41). The highest risk was found for betel quid chewers, where the increased risk observed was more than six times (RR 6.75, 95%CI 3.32-13.72). Alcohol consumption on its own did not seem to confer an increased risk for OPMD, however when practiced concurrently with smoking, a significant risk of more than five times was noted (RR 5.69 95%CI 3.14-10.29). CONCLUSION: The prevalence of OML was 54.1%, with linea alba being the most commonly occurring lesion. Smoking, alcohol consumption and betel quid chewing were found to be associated with the prevalence of OPMD, which was 5.6%.

Iatrogenic displacement of high-speed bur during third molar removal.

Surgical removal of impacted mandibular third molar is a routine procedure in oral surgery. Various iatrogenic complications related to the procedure has been discussed well in the literatures before. Some of these complications are related to the wrong usage of instruments and techniques. Here we discuss a rare complication on a 42-year-old male, related to the use of high-speed handpiece drill in mandibular third molar removal in a general dental office setting. He was referred when a high speed tungsten carbide bur was accidentally broken and displaced into the mandibular bone during surgical procedure. It is not common to use a high-speed handpiece in impacted third molar removal. This iatrogenic complication could have been totally avoided with the use of proper equipment and technique; therefore raising awareness regarding wrong usage of instrument is vital to avoid similar incidents in the future.

Posttraumatic growth, depression and anxiety in head and neck cancer patients: examining their patterns and correlations in a prospective study.

BACKGROUND: Positive and negative psychological reactions have been described in head and neck cancer patients. Nevertheless, the relationships between these responses across time need to be studied to understand the patients' strengths and vulnerabilities. OBJECTIVES: The aim of this study is to determine the changes in posttraumatic growth (PTG), depression and anxiety longitudinally and the correlations between PTG and depression and anxiety in head and neck cancer patients. METHODS: A prospective study was conducted on 60 head and neck cancer patients within a year of diagnosis recruited from an oncology referral centre in Malaysia with 50 patients completing the study. The PTG Inventory-Short Form (PTGI-SF) and Hospital Anxiety and Depression Scale (HADS) were used at baseline and at 6 months follow-up. RESULTS: There were significant reductions in the scores of PTGI-SF (mean difference = -5.5, p = 0.014), HADS (Depression) (mean difference = -2.0, p < 0.05) and HADS (Anxiety) (mean difference = -2.0, p < 0.05) from baseline to follow-up. However, their correlations were not significant. HADS (Depression) score at baseline showed weak inverse correlation with PTGI-SF score (rho = -0.147, p = 0.309), whereas PTGI-SF score had weak positive correlations with HADS (Anxiety) at baseline (rho = 0.261, p = 0.067), HADS (Depression) at follow-up (rho = 0.083, p = 0.566) and HADS (Anxiety) at follow-up (rho = 0.111, p = 0.445). HADS scores also did not predict total PTGI-SF score longitudinally. CONCLUSION: There were reductions in PTG, depression and anxiety within a year of cancer diagnosis and 6 months later with no significant correlations between PTG with depression and anxiety.

Maxillofacial injuries and traumatic brain injury--a pilot study.

BACKGROUND: Maxillofacial injuries comprising hard tissue as well as soft tissue injuries can be associated with traumatic brain injuries due to the impact of forces transmitted through the head and neck. To date, the role of maxillofacial injury on brain injury has not been properly documented with some saying it has a protective function on the brain while others opposing this idea. AIM: This cross-sectional retrospective study evaluated all patients with maxillofacial injuries. The aim of the study was to analyze the occurrence and relationship of maxillofacial injuries with traumatic brain injuries. MATERIAL AND METHODS: We retrospectively studied the hospital charts of all trauma patients seen at the accident and emergency department of UKM Medical Centre from November 2010 until November 2011. A detail analysis was then carried out on all patients who satisfied the inclusion and exclusion criteria. RESULTS: A total of 11294 patients were classified as trauma patients in which 176 patients had facial fractures and 292 did not have facial fractures. Middle face fractures was the most common pattern of facial fracture seen. Traumatic brain injury was present in 36.7% of maxillofacial cases. A significant association was found between facial fractures and traumatic brain injury (P < 0.05). Patient with facial fractures had a 1.5 increased risk of having a traumatic brain injury (95% CI 1.197-1.909). CONCLUSION: Patients with maxillofacial injuries with or without facial fractures are at risk of acute or delayed traumatic brain injury. All patients should always have proper radiological investigations together with a proper observation and follow-up schedule.

Coping processes relevant to posttraumatic growth: an evidence-based review.

OBJECTIVE: This study aims to perform an evidence-based review on the quantitative data regarding coping processes related to posttraumatic growth in the field of oncology to facilitate understanding of posttraumatic growth in oral cavity cancer (OCC) patients. MATERIAL AND METHODS: Pubmed, Medline, and PsycINFO were used for the search and the reference list checked for each selected article. Full articles meeting the inclusion criteria were retrieved. Only English articles were included. RESULTS: The initial search yielded 934 publications; 64 "potentially relevant papers" and 21 "effective" papers formed the basis of this review. Personality traits and social support lead to development of positive coping methods in cancer patients. Overriding influences are benefit finding and meaning making. Specific coping processes were identified to be significantly associated with posttraumatic growth in patients suffering from different cancers and a need for additional prospective research regarding specific processes and outcomes among oral cavity cancer patients. A proposed theoretical model based on the evidence of management of other cancer research fields is suggested for patients with OCC. CONCLUSION: An evidence-based review of coping strategies related to posttraumatic growth was performed which identified key coping strategies and factors that enhance coping processes. A conceptual model of coping strategies to enhance posttraumatic growth in OCC patients based on the scientific evidence attained is suggested to provide a more holistic approach to OCC management.

The roles of hope and optimism on posttraumatic growth in oral cavity cancer patients.

To investigate the association of the positive coping strategies, hope and optimism, on posttraumatic growth (PTG) in oral cavity (OC) cancer patients. A retrospective cross-sectional study was conducted and performed in the outpatient station of the Oral and Maxillofacial Surgery at the University of Hong Kong, Hong Kong SAR, PR China. Fifty patients successfully treated for OC cancer were recruited after their informed consents had been obtained during the review clinic. During their regular follow-up controls in the outpatient clinic, the patients compiled the posttraumatic growth inventory (PTGI) questionnaire, hope scale (HS) and the life orientation scale-revised (LOT-R). Hope and optimism correlated significantly positive with PTG and accounting together for a 25% variance of posttraumatic growth. Hope positively correlated with posttraumatic growth (r=.49, p<.001) as well as optimism (r=.31, p<.05). When compared to unmarried patients, married patients showed high levels of PTG and hope (married participants: mean=53.15, SD=11.04; unmarried participants: mean=41.00, SD=6.36; t (48)=2.403, p<.05). Hope and optimism represent important indicators for PTG in OC cancer patients. An intact dyad relationship seems to be important for hope and consecutive higher levels of PTG when compared to unmarried patients. Supportive psychological treatment strategies related to these two coping factors might be beneficial for OC cancer patients.

Posttraumatic growth: a novel concept in oral cavity cancer care?

Recently the importance of posttraumatic growth (PTG), a phenomenon of positive psychological growth beyond baseline values, has been discovered in the field of oncology. An evidence based review of the literature regarding PTG was performed, both to support its understanding and to consider its application within the research field of oral cavity (OC) cancer. A Pubmed, Medline, PsycINFO search from the earliest date until April 2010 was carried out. Full articles meeting the inclusion and exclusion criteria were reviewed. The search yielded 852 papers, 91 'potentially relevant papers' and 29 'effective papers', the latter of which formed the basis of this review. PTG was assessed in twenty-eight studies with the Posttraumatic Growth Inventory and in only one study with the Perceived Benefits Scale (PBS). PTG in cancer patients has been reported in five main domains (i) appreciation of life, (ii) relating to others, (iii) increased personal sense, (iv) sense of new possibilities and (v) positive spiritual change. Socio-demographic factors, stressor characteristics and coping strategies influence and predict the development PTG. In the past decade an increasing interest in the concept of PTG in the field of oncology has emerged. This evidence based review presents PTG to the research community in the field of OC cancer, appraises its modification capacity of the treatment outcome in other cancer research fields and hypothesizes its eventual benefit in the field of OC cancer research.

Necrotizing gingivitis: a possible oral manifestation of ticlopidine-induced agranulocytosis.

Agranulocytosis is a rare complication of ticlopidine and can be life-threatening. We report a case of ticlopidine-induced agranulocytosis and neutropenia (neutrophil count of 0.1 x 10(9)/L) with necrotizing gingivitis in a 54-year-old Malaysian-Chinese female. She was started on ticlopidine 250 mg twice daily 3 weeks prior to this hospital admission. We started her on intravenous metronidazole and amoxicillin and clavulanic acid (Augmentin) and concurrently stopped ticlopidine. A series of clinical and laboratory investigations were carried out and a final diagnosis of necrotizing gingivitis possibly secondary to agranulocytosis was made. The patient was discharged home after 2 weeks of hospitalisation.
