Teeth were photographed and evaluated using visual scoring protocols to assess plaque accumulation, enamel wear, and other anomalies across all incisors. Plaque scoring revealed a median plaque score of 3 (IQR ± 1) on buccal surfaces and 2 (IQR ± 2) on lingual surfaces, indicating substantial plaque accumulation across incisors. Two cases of geminated incisors and one case of fused central incisors were identified, representing the first documented cases in sheep and expanding existing knowledge of dental anomalies in sheep. Dental wear assessments showed that 13% of 10-month-old ewes and 33% of 20-month-old ewes had significant enamel loss or pulp exposure, with an average of 2 teeth per affected ewe displaying pulp necrosis. Amelogenesis imperfecta was recorded in 5% of the younger and 37% of the older groups. Missing incisors, suggesting early dentition changeover, were observed in 9% of 20-month-old sheep. Localized enamel hypoplasia, potentially resulting from trauma or disruptions during enamel development, was noted in 1% of both age groups. Dental caries was identified in five 20-month-old ewes with permanent incisors. These findings provide a comprehensive overview of the range and prevalence of dental conditions in Merino sheep, including common wear patterns and rare anomalies. Documenting such conditions in sheep contributes valuable information to veterinary dentistry, highlighting the need for further research into incisor health in sheep.","PeriodicalId":17584,"journal":{"name":"Journal of Veterinary Dentistry","volume":" ","pages":"8987564251339058"},"PeriodicalIF":0.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144024411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two-hundred and ninety-five koalas from free-range and captive colonies were examined to determine their oral health status. Two hundred koalas were classified as free-range, whilst 95 were captive from three separate zoological parks. Observations were made using the Koala Oral Health Chart which results in three major indices: the General Oral Cavity Index (GOCI), Oral Health Index (OHI), and Final OHI (FOHI), which describe the current oral health of the population. Eighty-six percent of the koalas had one oral health problem, with 42% of these koalas classified as old aged. The FOHI average from the whole population was 3.76 (SD 3.19, SE 0.20, median 3.00, range 0.14-15.98) with a high variance in individual indices scores. The frequencies of FOHI scoring also showed significant differences between tooth wear classes (TWC) (P = .000), with a sharp increase by TWC 3. This also occurred with the GOCI. The GOCI physical abnormalities were recorded in 141 koalas, with a median of three conditions per koala. Oral Health Index scores were recorded for 219 koalas with the highest of 8.40 in a TWC 7 female. Zoo 3 had significantly healthier oral cavities when the highest FOHI levels of each group was assessed (Zoo 1, 11.42; Zoo 2, 13.40; Zoo 3, 4.13; free-range, 15.98). The FOHI severity levels between free-range and captive koalas based on sex and TWC showed significant variation (sex, P = .000; TWC, P = .000). This study provides index values that can be used for comparison with other koalas or other species in the future.","PeriodicalId":17584,"journal":{"name":"Journal of Veterinary Dentistry","volume":" ","pages":"8987564251334539"},"PeriodicalIF":0.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144015524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study describes these forces on incisor teeth in horses during odontoplasty of cheek teeth under sedation. Measurements were documented using a modified \"Günther\" mouth speculum fitted with a force transducer along the force axis. Forces were recorded for different incisor separation distances and for dental rasping at a defined incisor separation distance. The results showed a significant difference in the median loads on the incisors at 82 mm (198.88 N), 92 mm (214.18 N), and 102 mm (293.95 N) incisor separation distance, and between active treatment with a mechanical bur (173.28 N) and no active mechanical bur (237.81 N) with maximum peaks up to 3783.60 N. Increasing bodyweight and mandible length showed a correlation with increasing forces, whereas age, gender and regularity of dental treatments did not suggest any influence on force development.","PeriodicalId":17584,"journal":{"name":"Journal of Veterinary Dentistry","volume":" ","pages":"8987564251336397"},"PeriodicalIF":0.7,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144029735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nine cats were reviewed for signalment, history and physical examination, diagnostic workup, tumor type, mandibulectomy extension, lymph node removal as well as both intraoperative and postoperative complications. The performed surgical procedure was a combination of an extraoral approach ventrally to the mandible and an intraoral approach to remove the whole or a part of the mandible. Lymphadenectomy was achieved using the same surgical access. None of the cats had intraoperative complications. Postoperative complications were limited to regional swelling and drooling lasting a week. Seven cats were able to eat immediately after the surgery. Of the other 2 cats, 1 regained the ability to eat within a month and 1 only ate from the owner's hands. The surgical approach for mandibulectomy described allowed better access and visualization of the caudal part of the mandible and direct access to regional lymph nodes. Moreover, if the expected postoperative malocclusion is managed during the same surgical procedure, there is a higher rate of postoperative eating ability compared to what is reported in the literature.","PeriodicalId":17584,"journal":{"name":"Journal of Veterinary Dentistry","volume":" ","pages":"235-241"},"PeriodicalIF":0.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141076221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most B. babyrussa maxillary molar teeth had six roots, with small numbers of teeth having four, five or seven roots. A similar pattern was suggested in B. celebensis. Mandibular molar teeth had between four and eight roots. Tooth roots of maxillary and mandibular first and second molar teeth were largely tapering, rod-like structures. The roots of the right and left maxillary third molar teeth had a more complex arrangement; some were inserted almost vertically into the maxilla; others were orientated in a more distal direction. The mesial and distal roots were splayed in appearance. The right and left mandibular third molar tooth roots retained elements of the open 'C' shape and were generally orientated distally. The pulp chambers were arched to fit under the main cusps in all molar teeth. Pulp canals were variable in number.","PeriodicalId":17584,"journal":{"name":"Journal of Veterinary Dentistry","volume":" ","pages":"189-201"},"PeriodicalIF":0.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11894872/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140863659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Being clinically asymptomatic in early stages but progressively destructive and painful in many cases highlights the need for improvements in early diagnosis of EOTRH. This study describes how clinical and radiological findings correlate with distinguishing EOTRH-specific symptoms from non-specific findings. Clinical and radiographic examinations of the rostral oral cavity were performed in 154 Icelandic horses. Each horse received a separate assessment of clinical and radiographic findings and was clinically and radiographically classified as either EOTRH Stage 0 (no findings), Stage 1 (suspicious), Stage 2 (mild), Stage 3 (moderate) or Stage 4 (severe). Analysis revealed statistically significant association between non-age-correlated bite angle, fistulae, gingival swelling, gingival recession as well as gingivitis and radiographic EOTRH diagnoses. Meanwhile, no statistical association was found between the occurrence of calculus or tooth mobility and EOTRH diagnosis. Understanding the interaction of the different symptoms enables further diagnostics (e.g., radiography) to be conducted at an early stage, and therefore EOTRH can be diagnosed and treated at its earliest possible stage.","PeriodicalId":17584,"journal":{"name":"Journal of Veterinary Dentistry","volume":" ","pages":"202-211"},"PeriodicalIF":0.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143189235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 5-year-old Russian Blue cat was presented with a complicated crown fracture (pulp exposure) of its left maxillary canine tooth (204). To salvage the tooth, root canal therapy was initiated but not completed due to hemorrhage within the canal. The procedure was staged. On recovery from the procedure, unilateral facial swelling and corneal ulceration were observed. This was consistent with retrograde passage of sodium hypochlorite through the nasolacrimal duct, inducing chemical injury to the cornea. The patient was treated with topical antibiotics, ophthalmic lubrication and systemic analgesia. After seven days of treatment, vast improvements to the eye were noted, with a full recovery confirmed at subsequent follow-up. Rather than complete stage two of the root canal therapy, the affected tooth was extracted; due to progression of pathology affecting the periapical bone. Clinicians should be aware of retrograde chemical irrigation as a potential complication when undertaking root canal therapy of maxillary canine teeth in cats. The close association between the maxillary canine tooth root and the nasolacrimal duct in cats needs to be taken into consideration and may require further evaluation prior to undertaking endodontic treatment. Advanced imaging should be considered. Immediate management of chemical corneal injuries should include copious flushing of the corneal surface, followed by swift referral for ophthalmic assessment.","PeriodicalId":17584,"journal":{"name":"Journal of Veterinary Dentistry","volume":" ","pages":"226-234"},"PeriodicalIF":0.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142853900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The efficacy of dental products in dogs that have not had their teeth professionally cleaned (\"dirty tooth model\") has been studied far less often. Some dogs for which professional dental cleaning is indicated will not have their teeth cleaned because of anesthetic risk or for other reasons. In this study, 6 dental homecare products were evaluated against a negative control group; none of the dogs received professional dental cleaning at the start of the study. The home care protocols tested were: brushing every other day using a toothpaste, feeding a dental chew once daily (VF), adding a water additive in the water daily (AQ), brushing once a week + VF daily, brushing once a week + AQ daily, VF + AQ daily. Dental deposits (plaque and calculus) and periodontal health were assessed on awake dogs, before and after receiving the assigned homecare regimen for 8 weeks. Results were compared with an untreated control group. Dental deposits were reduced by regular mechanical action (brushing or VF daily). Periodontal health status was improved when AQ daily was combined with either brushing once a week or VF daily. Two scoring techniques useful for determining a recommendation from a veterinarian to commence home oral hygiene or recommend dental scaling as a necessary first step are described.","PeriodicalId":17584,"journal":{"name":"Journal of Veterinary Dentistry","volume":" ","pages":"176-181"},"PeriodicalIF":0.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11894899/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142716562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
