Efficacy of photodynamic therapy on candida colonization and clinical symptoms in denture stomatitis: a systematic review and meta-analysis

BACKGROUND

Photodynamic therapy (PDT) has been recently proposed as a promising alternative therapy for Denture Stomatitis (DS). The present systematic review and meta-analysis investigated the current available evidence regarding the efficacy of PDT in the management of DS.

MATERIALS AND METHODS

PubMed, Scopus, Web of Science, Google Scholar, and ProQuest were searched up to June 7, 2023. All relevant clinical trials were included. RevMan software was used for the statistical analyses.

RESULTS

Elven randomized clinical trials (460 DS patients) were included. Eight studies assessed the efficacy of PDT vs. topical antifungal therapy, while three studies assessed the adjunctive use of PDT (PDT + antifungal therapy) vs. topical antifungal therapy alone. The results revealed comparable efficacy of PDT and conventional antifungal therapy on candida colonization at 15 days (MD: 0.95, 95% CI: -0.28, 2.19, p = 0.13) and at the end of follow-up (MD: -0.17, 95% CI: -1.33, 0.98, p = 0.77). The pooled two studies revealed relatively better efficacy of adjunctive use of PDT with antifungal therapy on candida colonization compared to antifungal therapy alone at 15 days (MD: -6.67, 95% CI: -15.15, 1.82, p = 0.12), and at the end of follow-up (MD: -7.14, 95% CI: -19.78, 5.50, p = 0.27). Additionally, the results revealed comparable efficacy of PDT and topical antifungal therapy on the clinical outcomes.

CONCLUSIONS

PDT might be considered a viable option for DS either as an adjunct or as an alternative to the topical antifungal medications. Further studies with adequate sample sizes and standardized PDT parameters are warranted.

Barriers and enablers for oral health promotion programs amongst primary healthcare stakeholders in Qatar - a qualitative investigation

BACKGROUND

Oral health of preschool children remains a concern globally. Primary healthcare providers are in a vital position to support preventive oral care programmes. This study explored current practices, perception and barriers of primary health care professionals towards oral health promotion program of children in Qatar.

METHODS

The qualitative research used focus group discussions and interviewed a total of 108 participants that were audio recorded and transcribed verbatim. Four major themes emerged and were analysed to explore contextual patterns within the data.

RESULTS

Participants acknowledged the high prevalence of caries in children and identified the causes in the local context which included parental practices, poor dietary habits, impact of culture lack of oral health knowledge, limitations in the healthcare system, and negative role of the media. However, complex barriers were exposed, including lack of time and ownership, system coordination between organizations, and lack of policy.

CONCLUSION

Health professionals and bureaucrats involved in decision-making held a positive attitude towards oral health prevention programs and were enthusiastic to initiate and support these programs.

The impact of periodontal disease on the clinical outcomes of COVID-19: A systematic review and meta-analysis

BACKGROUND

A possible relationship between periodontitis (PD) and COVID-19 and its adverse outcomes has been suggested. Hence, the present systematic review and meta-analysis aimed to investigate the available evidence regarding the potential association between periodontitis (PD) and COVID-19 and its adverse outcomes.

MATERIALS AND METHODS

PubMed, Scopus, Web of Science, and Google Scholar were searched for relevant studies published up to April 15th, 2023. Studies that evaluated the association between PD and COVID-19 were included. Risk of bias was evaluated by two reviewers, and meta-analyses were performed using RevMan 5.3 software.

RESULTS

A total of 22 studies involving 92,535 patients from USA, Europe, Asia, the Middle East and South America were included; of these, 12 were pooled into the meta-analysis. Most of the studies (19 studies) reported a significant association between PD and COVID-19. The pooled data found a significant association between PD and COVID-19 outcomes: more severe symptoms (OR = 6.95, P = 0.0008), ICU admissions (OR = 3.15, P = 0.0001), and mortality (OR = 1.92, P = 0.21). Additionally, compared to mild PD, severe PD was significantly associated with higher risks of severe COVID-19 outcomes: severe symptoms (P = 0.02); ICU admission (P = 0.0001); and higher mortality rates (P = 0.0001). The results also revealed 58% higher risk for COVID-19 infection in patients with PD (P = 0.00001).

CONCLUSIONS

The present findings suggest a possible association between poor periodontal health and the risk of poor COVID-19 outcomes. However, owing to the observed methodological heterogeneity across the included studies, further prospective cohort studies with standardized methodologies are warranted to further unravel the potential association between periodontal disease and COVID-19 and its adverse outcomes.

Periodontal and peri-implant status and whole salivary interleukin 1-beta levels among individuals using selective serotonin reuptake inhibitors: an observational study

OBJECTIVE

Selective serotonin reuptake inhibitors (SSRI) are commonly used for managing psychological diseases such as depression. These disorders are also directly associated with periodontal and peri-implant diseases, namely periodontitis and peri-implantitis, respectively. It is hypothesized that there is no difference in periodontal and peri-implant clinicoradiographic status and unstimulated whole salivary interleukin (IL)-1β levels in participants using selective serotonin reuptake inhibitors (SSRI) and controls (individuals not using SSRI). The aim of the present observational case-control study was to compare periodontal and peri-implant clinicoradiographic statuses and whole salivary IL-1β in participants using SSRI and controls.

METHODS

Users of SSRI and controls were included. In all participants, periodontal (plaque index [PI], gingival index [GI], probing depth [PD], clinical attachment loss [AL] and marginal bone loss [MBL]) and peri-implant (modified PI [mPI], modified GI [mGI], PD and crestal bone loss [CBL]) were assessed. Unstimulated whole saliva was collected and IL-1β levels were determined. Information related to duration of implants in function, duration of depressive symptoms and treatment of depression was retrieved from healthcare records. Sample-size was estimated using 5% error and group comparisons were performed. P < 0.05 was considered statistically significant.

RESULTS

Thirty-seven SSRI users and 35 controls were assessed. Individuals using SSRI had a history of depression of 4.2 ± 2.5 years. The mean age of SSRI-users and controls were 48.7 ± 5.7 and 45.3 ± 5.1 years, respectively. Tooth brushing twice daily was reported by 75.7% and 62.9% SSRI-users and controls, respectively. There was no statistically significant difference in PI, mPI, GI, mGI, PD, clinical AL, numbers of MT and mesial and distal MBL and CBL among individuals using SSRI compared with controls (Tables 3 and 4). The unstimulated whole salivary flow rate in individuals using SSRI and controls was 0.11 ± 0.003 and 0.12 ± 0.001 ml/min, respectively. Whole salivary IL-1β levels in individuals using SSRI and controls were 57.6 ± 11.6 pg/ml and 34.6 ± 5.2 pg/ml, respectively.

CONCLUSION

Users of SSRI and controls demonstrate healthy periodontal and peri-implant tissue statuses with no marked differences in whole salivary IL-1β levels provided oral hygiene is stringently maintained.

Management of Chronic Atrophic Candidiasis (Denture Stomatitis)-A Narrative Review

One of the most common oral diseases affecting people wearing dentures is chronic atrophic candidiasis or denture stomatitis (DS). The aim of the paper is to provide an update on the pathogenesis, presentation, and management of DS in general dental practice settings. A comprehensive review of the literature published in the last ten years was undertaken using multiple databases, including PubMed via MEDLINE, EMBASE, and Scopus. The eligible articles were analyzed to identify evidence-based strategies for the management of DS. Despite its multifactorial nature, the leading cause of DS is the development of oral Candida albicans biofilm, which is facilitated by poor oral and denture hygiene, long-term denture wear, ill-fitting dentures, and the porosity of the acrylic resin in the dentures. DS affects between 17 and 75% of the population wearing dentures, with a slight predominance in elderly females. The mucosal denture surfaces and posterior tongue are the common sites of DS, and the affected areas exhibit erythema, the swelling of the palatal mucosa and edema. Oral and denture hygiene protocols, adjusting or re-fabricating poorly adapting dentures, smoking cessation, avoiding nocturnal denture wear, and the administration of topical or systemic antifungals are the mainstay of management. Alternate treatments such as microwave disinfection, phytomedicine, photodynamic therapy, and incorporation of antifungals and nanoparticles into denture resins are being evaluated for the treatment of DS but require further evidence before routine use in clinical practice. In summary, DS is the most common oral inflammatory lesion experienced by denture wearers. Most patients with DS can be managed in general dental practice settings. Effective management by general dental practitioners may be supported by a thorough understanding of the pathogenesis, the recognition of the clinical presentation, and an awareness of contemporary treatment strategies.

Development of professional identity among dental students - A qualitative study

PURPOSE

The study explored dental students' perception of their professional identity (PI) development at a newly established dental college with a problem-based learning (PBL) curriculum.

METHODS

Qualitative methods based on focus groups were used for data collection. The conceptual framework of the study was informed by a subject-centered sociocultural approach to PI development. Purposive sampling was used to collect data from five focus groups of undergraduate dental students to gain a deeper understanding of their PI development in a PBL environment.

RESULTS

Out of a total of 38 dental students in years 2 and 3, 34 students (89.47%) participated in the focus groups. A theory-driven thematic analysis was used to dissect the views and experiences of the participants to explore factors contributing to PI development in the early years of the program. At an individual level, PBL was seen to be appropriate for PI development. However, some participants placed more emphasis on practical training in operative dental skills. Relational sources especially role modeling by the PBL facilitators and faculty staff were identified as a key factor to nurture PI development. Mixed views were observed on the value of PBL to enhance team-working skills. The participants also identified challenges of PBL and provided recommendations on further improvements to enhance the learning experiences of the students.

CONCLUSIONS

This study provided useful insights into a PBL curriculum at a newly established dental institution. The findings underscore the value of PBL in developing PI and also highlight the challenges of implementing PBL in a socio-cultural context and pedagogical implications for further program improvement.

Oral-Health-Related Self-Efficacy among the Elderly Population in Riyadh, Saudi Arabia

Oral health self-efficacy is a fundamental determinant of behavioral changes among elderly patients. Objective: To assess the oral self-efficacy among the Saudi population aged 65 years old and above in Riyadh, Saudi Arabia. Methodology: This was a cross-sectional survey conducted on elderly individuals in Riyadh. An Arabic version of the Geriatric Self-Efficacy Scale for Oral Health (GSEOH) was administered to all participants. The dependent variables included oral function, oral hygiene habits, and dental visits. For the statistical analysis, two independent sample t-tests and a one-way ANOVA test were used. Significance was judged at a p-value less than 0.05. Results: Of 400 participants recruited, 53% were males. About 58% had retained teeth, and 72% had visited a dentist in the past 12 months. Overall, 31.6%, 34.64%, 22.65%, and 11.14% of the participants rated their oral health as good, fairly good, rather poor, and poor, respectively. Age (p < 0.001), educational level (p < 0.001), and working status (p < 0.001) were significantly associated with GSEOH scores. Other sociodemographic characteristics were not found to affect the GSEOH scores. Conclusions: The overall self-efficacy of oral health among Saudi elderly individuals is fairly good. Age, educational level, and occupational status are the main determinants of oral health self-efficacy scores.

Aragonite toothpaste for management of dental calculus: A double-blinded randomized controlled clinical trial

Objectives

Aragonite from animal origin such as cuttlefish bone powder is an abrasive with hardness properties ideal for calculus removal. The purpose of this randomized controlled trial was to test the efficacy of a cuttlebone‐derived aragonite toothpaste in removing dental calculus.

Materials and Methods

Eighty‐one patients who fulfilled the inclusion criteria were blindly and randomly assigned into two study groups. The intervention treatment group (n = 40) received cuttlebone toothpaste (Dr. D‐Tart) and the control group (n = 41) received an off‐the‐shelf commercial toothpaste (Crest). Evaluations were performed before and after scaling and polishing procedures done at 3 months in order to evaluate the toothpaste's ability to remove calculus and to prevent calculus formation. Calculus, stains, plaque, and gingival indices scores, and patient satisfaction surveys were compared at baseline (first visit), 3, and 9 months, using generalized linear models and Wald's χ² test.

Results

At the end of the 3‐month period, the intervention group showed a 30% reduction in total calculus compared to the baseline score (p = .0006) and 45% less total calculus compared to the control group (p = .0001). Six months after scaling, the mean calculus score for Crest users was 42% higher than that for Dr. D‐Tart users (p = .0692). There was a significant improvement in the gingival health of cuttlebone toothpaste users at the observed intervals, and both kinds of toothpaste achieved comparable results in terms of plaque and stains removal.

Conclusions

Aragonite toothpaste can remove calculus, prevent calculus formation, and improve gingival health. Patients are generally satisfied with the performance of the aragonite toothpaste. Clinical significance: Animal‐derived aragonite toothpaste (Dr. D‐Tart) shows promising efficacy in removing calculus, preventing calculus formation, and for the improvement of gingival health. Clinical trial ID: A08‐M35‐16B.

Structural integrity of extracted teeth restored using three different post-and-core systems: An in vitro comparative study

Aim

The objective of the study was to assess the in vitro fracture resistance of endodontically treated teeth restored using different post-and-core materials.

Materials and methods

Extracted human mandibular premolars (n = 36) were extracted teeth and equally distributed into four (4) treatment groups: cast metal post-and-core, milled zirconia post-and-core, pre-fabricated post with composite resin core and control group. These samples were then each subjected to the load to fracture test using a universal testing machine. Fracture resistance data were compared among groups by analysis of variance and Fisher’s exact test.

Results

The highest mean fracture resistance value was observed in the zirconia post-and-core treatment group (1567.26 ± 317.66 N), followed by the cast metal (1355.92 ± 621.56 N) and lastly the pre-fabricated post with composite resin core (725.67 ± 251.05 N) treatment group. Differences among groups were not statistically significantly different (P = 3.77).

Conclusion

Endodontically treated mandibular premolars with a zirconia post-and-core system exhibited the highest robustness against structural failure based on its mean fracture resistance value. In addition, extracted teeth restored with cast post-and-core resisted a greater stress load than those restored with fiber-reinforced posts. Zirconia showed a more favorable fracture mode than the other restorations.

Golden proportion evaluation in maxillary anterior teeth amongst Saudi population in Riyadh

Introduction

In achieving pleasing dental aesthetics, the maxillary anterior teeth are essential. Numerous methods are used to measure their dimensions, including the golden proportion between their perceived widths and the width-to-height ratios, referred to as the golden proportion and is considered as a gold standard for esthetic evaluation.

The objective of this study was to evaluate the existence of the golden proportion between the width of the maxillary anterior teeth of Saudi males and females.

Methods

This clinical observational study included a total of 61 participants that met the inclusion criteria having 36 females and 25 males, all Saudi nationals, presented to Princess Nourah bint Abdulrahman University (PNU), College of dentistry, clinics. Dental casts of the maxillary arches for each participant were made after taking digital impressions in addition to taking photographs. The dimensions and the perceived width of the anterior teeth viewed from the front were measured using a digital caliper. SPSS was used to analyze the data.

Results

There were significant differences between the subject’s width-to-height ratios and the golden proportion of 0.80 where (p-value < 0.05). Thus, indicating that no golden ratio was observed except in case of tooth number 12 in male subjects where mean value was (0.83) with a standard deviation of (0.09) and the p-value of (p = 0.144) > 0.05.

Conclusions

From the perceived widths of maxillary anterior teeth, the golden proportion was not found to exist. No gold standard was detected for the width-to-height proportions of maxillary incisors. Therefore, in addition to anterior teeth measurements, specific population characteristics and perception of an agreeable smile should be considered for evaluating esthetics.

An RCT of atraumatic restorative treatment for older adults: 5 year results

OBJECTIVES

to compare the survival of ART and a conventional restorative technique (CT) for restoring carious lesions in older adults after 5 years.

METHODS

In this parallel randomised controlled clinical trial, 219 independently-living adults were recruited from a dental hospital/community and a geriatric day hospital. Ninety-nine patients who met the inclusion criteria and presented with carious lesions were randomly allocated to receive either ART or conventional restorations (anaesthesia, rotary instruments and resin-modified glass ionomer). The status of restorations was assessed 6 months, 1, 2 and 5 years after restoration placement. Estimates of cumulative survival were calculated for each interval between assessments and a Cox Proportional Hazards (PH) model was fitted to the interval-censored survival time.

RESULTS

Three hundred restorations (ART n=142; CT n=158) were placed on 99 patients, 46 males and 53 females, with a mean age of 73.2, SD: 6.8 (65-90 yrs). After 5 years, ART and CT presented cumulative probability of survival of 85% and 79% (p=0.8095), respectively.

CONCLUSIONS

ART presents survival rates comparable to a conventional technique, when treating older adults after 5 years. The ART approach could be a useful tool to provide dental care for older adults particularly in the nonclinical setting. (Trial Registration number: ISRCTN 76299321).

CLINICAL RELEVANCE

This study shows that ART presents survival rates comparable to conventional techniques to treat carious lesions in older patients after 5 years. It is well accepted by this age cohort, and therefore could be an alternative to treat the elderly, especially those who are homebound or cannot attend the dentist.

A prospective study of the performance of resin bonded bridgework in patients with hypodontia

Congenital absence of teeth presents a number of clinical challenges in young patients, and little is known about the success rate of restorative dental treatment in these patients. The aim of this study was to conduct a prospective clinical study of the performance of resin bonded bridges in patients with hypodontia.

METHODS

A prospective clinical observation study was undertaken in Cork Dental School and Hospital, Ireland. Forty patients (22 males, 18 females; age range 18-21 years) with a confirmed diagnosis of hypodontia rated as mild (n=26), moderate (n=8) or severe (n=6) participated. Following completion of the orthodontic phase of care, all patients had missing teeth restored with resin bonded bridgework (RBB) using a standardised protocol (48 FF; 17CL design). Patients were followed up for 24 months, with recall visits at 6, 12 and 24 months following provision of RBBs.

RESULTS

65 RBBs were provided, 49 in the maxilla and 16 in the mandible; 43 bridges replaced anterior teeth and 22 replaced posterior teeth. After 24 months, 63 bridges were still in function and deemed to satisfy the preset criteria for success and survival. Two posterior bridges had failed due to repeated debond, and this was attributed to occlusal overload. 20% of the patients demonstrated some evidence of post orthodontic relapse, but this did not require further intervention.

CONCLUSION

In the short to medium term, resin bonded bridgework provides a reliable and minimally invasive solution for replacing missing teeth in patients with hypodontia.

The use of the Oral Health Impact Profile to measure the impact of mild, moderate and severe hypodontia on oral health-related quality of life in young adults

There is limited understanding of the subjective impact of congenital absence of teeth in patients with hypodontia. This study aimed to investigate the impact of mild, moderate and severe hypodontia on oral health-related quality of life (OHRQoL) and its relationship to age, gender and extent of hypodontia prior to treatment. 82 patients (43 females and 39 males, age range from 16 to 34 years) with a confirmed diagnosis of non-syndromic hypodontia were recruited for this study prior to treatment. Demographic details were recorded and a clinical examination documented the number and location of missing teeth. Participants were also asked to complete an oral health-related quality of life measure, the OHIP-49. The impact was of hypodontia was significant, with appearance concerns being the most prevalent impacts on oral health-related quality of life. Gender was a significant predictor of the overall OHIP-49 score, with females having higher level of impacts. The number and location of missing permanent teeth was not a good predictor of quality of life. However, location of missing teeth was a predictor of the psychological discomfort subscale score. There was a positive correlation between age and the functional limitation and physical disability subscale scores. This study shows that the impact of hypodontia on oral health-related quality of life is substantial.

The impact of hypodontia: a qualitative study on the experiences of patients

Congenital absence of teeth affects 2-6 per cent of the population, but its impact on quality of life (QoL) is not fully understood. The symptoms of hypodontia can vary and therefore also the treatment and management of this condition. Determining and understanding the possible impact of hypodontia on patients could inform and improve the management of such patients. A purposive sample of 10 participants aged 16-25 years (five males and five females) with mild, moderate, or severe hypodontia at various stages of treatment was recruited. The participants had previously completed a 49-item Oral Health Impact Profile (OHIP) questionnaire with summary scores ranging from 24 to 143. All subjects participated in semi-structured interviews, and these were transcribed and analysed using NVivo software. The results show that the role of hypodontia patients in the treatment decision-making process changes significantly as they move from childhood to adulthood. Participants indicated dissatisfaction with the lack of communication with dental services throughout early adolescence as they became more cognizant of their condition which in turn led to concerns with regard to appearance which impacted on their psychosocial well-being. Hypodontia patients expect improved communication with dental practitioners and services as they become more cognizant of their condition and wish to become more actively involved in the decision-making process regarding their current and future treatment.
