Randomized Controlled Trial
BACKGROUND
The dissolution of dental calculus, safely and at home, is among the more challenging issues facing the over-the-counter healthcare industry. Pontis Biologics, Inc. has developed novel model of calculus development and structure and has formulated a dentifrice (Tartarase™) using digestive enzymes as active ingredients that is shown to dissolve dental calculus in this Proof of Principle clinical trial.
METHODS
This investigation was designed to evaluate the safety and efficacy of a novel enzyme formulation to remove existing calculus deposits in 4 weeks, measured using the Volpe-Manhold Index (V-MI) on lingual surfaces of 6 lower anterior teeth. The test formulation was compared to Crest Cavity Protection, as a control dentifrice. A total of 40 randomized test subjects began the study with 20 assigned to the control dentifrice and 20 assigned to the Tartarase groups (ten each, one brushing with Tartarase twice daily and one brushed with Tartarase and wore a dental tray filled with Tartarase for 30 min then brushed again with Tartarase, once daily).
RESULTS
The Crest group experienced a 12% increase in calculus, in contrast to the results of both Tartarase groups that experienced a 40% reduction in calculus in 4 weeks of unsupervised at home use of the Tartarase toothpaste formulation.
CONCLUSIONS
This proof of principle study demonstrates that a dentifrice, formulated along the lines of the Tartarase material, is capable of combating calculus accumulation using the same oral hygiene habits that are common worldwide.
TRIAL REGISTRATION
This trial was registered retrospectively at clinicaltrials.gov and has the Unique Identification Number: NCT06139835, 14/11/2023.

American Journal of Veterinary Research Jun 2024To evaluate the dental abnormalities by visually assessing the labial and buccal photographs in dogs and cats and analyze their prevalence based on age and breed.
OBJECTIVE
To evaluate the dental abnormalities by visually assessing the labial and buccal photographs in dogs and cats and analyze their prevalence based on age and breed.
ANIMALS
1,096 client-owned dogs and 775 client-owned cats.
METHODS
Data were collected from patients who visited 26 private veterinary clinics from January to December 2022. Each animal was evaluated through dental photographs taken from the labial and buccal sides. Correlations between the prevalence of the identified dental abnormalities and age, craniofacial type, and breed, were analyzed.
RESULTS
Calculus, discoloration, epulis, fractured teeth, gingival recession, gingivitis, malocclusion, missing teeth, and persistent deciduous teeth could be identified by analyzing the dental photographs in both dogs and cats. Enamel defects in dogs and tooth resorption in cats could be identified. Brachycephalic dogs had a significantly higher prevalence of malocclusion (OR, 1.93; 95% CI, 1.36 to 2.75) and missing teeth (OR, 3.63; 95% CI, 2.71 to 4.91) compared to nonbrachycephalic dogs. Brachycephalic cats had a significantly higher prevalence of fractured teeth (OR, 1.95; 95% CI, 1.24 to 3.04) and a lower prevalence of gingival recession (OR, 0.30; 95% CI, 0.15 to 0.55) compared to nonbrachycephalic cats. Calculus, persistent deciduous teeth, and possibly gingivitis could be identified in dogs and cats by analyzing labial and buccal photographs. The assessment of some dental abnormalities such as fractured teeth, missing teeth, and tooth resorption can be limited without a complete dental examination under anesthesia.
CLINICAL RELEVANCE
Although the assessment of dental conditions may be underestimated, the data on the prevalence of the dental abnormalities evaluated through the photographs could be utilized for screening dental diseases.

Randomized Controlled Trial
BACKGROUND
Bariatric surgery can cause oral health problems in individuals, such as an increase in dental caries, periodontal diseases and dental erosion, which can be avoided if oral health promotion actions are implemented.
AIMS
To assess the impact of an oral health promotion program implemented among gastroplasty patients.
METHODS
This randomized clinical trial involved 208 patients undergoing gastroplasty; they were divided into two groups: Intervention Group, with participation in the Oral Health Promotion Program for Bariatric Patients, or Control Group. Assessments were carried out preoperatively, and six and 12 months postoperatively. The oral conditions assessed were: dental caries, periodontal diseases, tooth wear, dental plaque, and salivary flow. Sociodemographic information was obtained through application of structured questionnaires. For data analysis, the Chi-Square, Fisher's Exact, and Mann-Whitney tests were performed - α=5%.
RESULTS
Patients in the Intervention Group, when compared to those in the Control Group, presented: fewer changes in enamel (6M: p<0.0001; 12M: p=0.001), in dentin (6M: p<0.0001; 12M: p<0.0001), moderate tooth wear (6M=0.002; 12M=0.005), gingival bleeding (6M: p<0.0001), dental calculus (6M=0.002; 12M: p=0.03), periodontal pocket 4-5 mm (6M=0.001; 12M: p=<0.0001); greater reduction in the bacterial plaque index (6M: p<0.0001; 12M: p<0.0001), and increased salivary flow (6M: p=0.019).
CONCLUSIONS
The oral health promotion program had a positive impact on the prevention and control of the main problems to the oral health of the gastroplasty patients.

The occupational stressors has an effect on overall health and dental health. Oral health is a vital aspect of general health. The current study was performed to assess the periodontitis among thermal power station workers in South India. Pilot study was done for 52 mine workers and based on the periodontal disease prevalence among them, the sample size was calculated as 603 subjects. The data collection was done using WHO 1997 proforma. Among the total study population, about 92 (30%) thermal power station 1 workers and 83 (28.1%) thermal power station 2 workers had pocket 4-5 mm, one (0.2%) thermal power station, 2 worker had pocket 6 mm or more thermal power station I workers, and 23 (7.8%) thermal power station 2 workers had 6 - 8 mm attachment loss. Only 1 (0.3%) thermal power station I worker had 9 - 11 mm attachment loss. In the current study, nearly 70% mine workers had calculus, nearly 30% had pocket 4-5 mm, and only 0.2% Mine II workers had pocket measuring 6 mm or more.

Peripheral ossifying fibroma (POF) is a reactive overgrowth that most commonly occurs on the gingiva. It is a benign oral soft tissue tumour. It is most commonly found on the anterior maxilla and has a female predilection. Most commonly found to occur in the second decade of life. This type of lesion originates from the cells of the periodontal ligament. It is often associated with trauma or local irritants, such as subgingival plaque and calculus, dental appliances and poor-quality dental restorations. This entity requires a proper treatment protocol and a regular follow-up. It can cause significant discomfort and irritation in the oral health if left untreated. The recurrence rate of the lesion varies according to the authors. This case report describes a case of POF in an adult female patient which was treated using surgical excision resulting in an uneventful healing during the post-operative period.

Gingival enlargement is a side effect of several different medication, including immunosuppressants, anticonvulsants, and calcium channel blockers. It is an inflammatory response that starts when plaque and calculus build up on the tooth surface. The most prevalent long-term neurological condition affecting people is epilepsy. In affluent nations, the prevalence of epilepsy is ~ 1%, whereas in less developed countries, it may >2%. The preferred medication for the condition, phenytoin, has major side effects include gingival enlargement. In addition to being visually disfiguring, this enlargement frequently affects speech, chewing and eating. Furthermore, those with poor dental hygiene, causes disabilities with motor coordination and muscular limitations leading to mental disability and physical impairments are more prone to periodontal disease. This article enlightened the mechanism of drug induced gingival enlargement clinically, microbiologically, and surgically.

OBJECTIVES
Calcifying nanoparticles (CNPs), referred to as nanobacteria (NB), are recognized to be associated with ectopic calcification. This study aims to isolate and culture CNPs from the dental plaque of patients with periodontal disease and investigate their possible role in unravelling the aetiology of periodontal disease.
MATERIAL AND METHODS
Supragingival and subgingival plaques were sampled from 30 periodontitis patients for CNPs isolation and culture. Alkaline phosphatase (ALP) content changes were tracked over time. Positive samples underwent thorough morphological identification via hematoxylin and eosin (HE) staining, Alizarin red S (ARS), and transmission electron microscopy (TEM). The chemical composition of CNPs analysis involved calcium (Ca) and phosphorus (P) content determination, Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD).
RESULTS
The subgingival plaque dental group exhibited a higher CNPs isolation rate at 36.67% (11/30) compared to the supragingival dental plaque group at 66.67% (20/30). ALP activity varied among the positive, negative and control groups. Morphological observation characterized the CNPs as round, oval, and ellipsoid particles with Ca deposits. Chemical analysis revealed the Ca/P ratio was 0.6753. Hydroxyl, methyl, carbonate, phosphate, hydrogen phosphate, and dihydrogen phosphate were detected by FTIR; the main chemical components detected by XRD were hydroxyapatite and tricalcium phosphate.
CONCLUSION
CNPs were found in periodontitis-related dental plaque and exhibited the potential to develop calcified structures resembling dental calculus. However, the potential involvement of ALP in CNPs formation requires deeper exploration, as does the precise nature of its role and the interrelation with periodontitis demand a further comprehensive investigation.

Review
One of the most promising areas of research in palaeomicrobiology is the study of the human microbiome. In particular, ancient dental calculus helps to reconstruct a substantial share of oral microbiome composition by mapping together human evolution with its state of health/oral disease. This review aims to trace microbial characteristics in ancient dental calculus to describe the evolution of the human host-oral microbiome relationship in oral health or disease in children and adults. Following the PRISMA-Extension for Scoping Reviews guidelines, the main scientific databases (PubMed, Scopus, Lilacs, Cochrane Library) have been drawn upon. Eligibility criteria were established, and all the data collected on a purpose-oriented collection form were analysed descriptively. From the initial 340 records, only 19 studies were deemed comprehensive enough for the purpose of this review. The knowledge of the composition of ancient oral microbiomes has broadened over the past few years thanks to increasingly well-performing decontamination protocols and additional analytical avenues. Above all, metagenomic sequencing, also implemented by state-of-the-art bioinformatics tools, allows for the determination of the qualitative-quantitative composition of microbial species associated with health status and caries/periodontal disease. Some microbial species, especially periodontal pathogens, do not appear to have changed in history, while others that support caries disease or oral health could be connected to human evolution through lifestyle and environmental contributing factors.

Periodontal instrument fractures are rare events in dentistry, with limited literature available on their occurrence and management. This case report highlights an incident involving the fracture of a periodontal sickle scaler blade during manual instrumentation for the removal of calculus. The fracture occurred during instrumentation on the mesial surface of the maxillary right second molar, and the separated blade was subsequently pushed into the sulcus. A radiographic assessment was performed to verify the precise location of the fractured segment. Following confirmation, the broken blade was subsequently retrieved using curved artery forceps. The case report highlights factors contributing to instrument fractures, emphasizing the importance of instrument maintenance, sterilization cycles, and operator technique. Ethical considerations regarding patient disclosure, informed consent, and instrument retrieval methods are well discussed. This case underscores the importance of truthful communication, the proper use of instruments, equipment maintenance in dentistry, and the significance of ongoing professional development to enhance treatment safety, proficiency, and ethical standards in dental care.

Tooth resorption (TR) is one of the most common dental diseases of cats. It is a painful condition leading to tooth loss. The etiology of TR remains unclear, but old age, breed, other oral and dental diseases, and environmental factors are suspected predisposing factors. In our study, we used part of the data from the extensive feline health online survey of 8115 Finnish cats. As TR is difficult to detect and as the feline health survey included diagnoses defined by both veterinarians and the owners, we limited our study to a subpopulation of cats diagnosed with oral or dental disease by a veterinarian and had dental examination or surgery under sedation (n=944). We utilized case-control study analysed by multivariable logistic regression to determine the risk factors and breed variation of feline TR. The 202 cats diagnosed with TR were defined as TR cases and the remaining 742 cats as controls. The frequency of veterinarian-diagnosed TR was 3.9% in the health survey data (316/8115) and 21% in the subpopulation (202/944). The risk of TR increased with age (14.7% in youngest and 25.3% in oldest age group). Our finding that TR was significantly associated with gingivitis or periodontitis in cats that had also calculus (OR: 2.49 and 3.70, respectively) suggests that inflammatory changes caused by calculus increase the risk of TR. We found that Cornish Rex, European, and Ragdoll are at higher risk for TR (OR: 2.44, 2.98 and 2.90, respectively). Exotic-Persians breed group had lower risk (OR: 0.28). TR was not observed in Turkish van or Devon Rex. The differences between breeds highlight a genetic contribution. In addition, female cats that had food available constantly had significantly less TR than female cats that had feeding times (OR: 0.44). The underlying reasons for this remain unexplained in our study.
