Key Indicators of success or survival for clinical performance of fixed partial denture

Annals of Dentistry.2019;26(1):53-58. doi:10.22452/adum.vol26no8

When fixed partial dentures (FPDs) are being suggested to patients, the frequent inquiry by patients is the anticipated longevity and length of service. Previous reports have provided limited information on the accurate measurements of good clinical outcome and the length of good years in service. This confuses the clinicians as well as the patients in determining the treatment of choice. In the present article, the indicator of ‘success’ and ‘survival’ will be discussed in determining the longevity of various FPDs such as conventional, resin bonded and implant retained. After reviewing the articles, it is good if the indicator of ‘success’ can be used as an indicator of longevity and good clinical outcome. Besides that, studies with at least 10 years of observation are probably of higher evidence for longevity of restorations.

Annals of Dentistry.2019;26(1):59-61. doi:10.22452/adum.vol26no9

The introduction of the recent 2017 classification of periodontal diseases has been welcomed by the periodontal fraternity. The new classification has used available evidence as the backbone for its development. It has been felt by many experts that a good understanding is required for its practice. Towards this, a Malaysian PerioSymposium was organised in May 2019 to comprehend the classification and also to identify the right path towards its learning among undergraduate students of dentistry in Malaysia. The symposium was conducted and moderated by local and international experts. Apart from the few limitations identified, the new classification was recommended to be taught in the undergraduate dental programme across schools in Malaysia.

Supriya Hulimane ; Mulki Shaila

Annals of Dentistry.2020;27(1):1-5. doi: 10.22452/adum.vol27no1

For a long time, oral exfoliative cytology (OEC) has been implemented as an effective preliminary diagnostic tool for pathological lesions and various methods for fixation of the cytology specimens have been studied. The present study was undertaken to compare the efficacy between the wet and spray type of fixation methods for Papanicolaou (PAP) stained oral cytosmears. The study comprised of 45 healthy subjects in the age group of 20-25 yrs. For each subject, two smears were collected from the buccal mucosa and subjected to wet and spray fixation methods respectively. Both the smears were stained using a commercial Rapid Pap Kit. Smears were observed microscopically and evaluated for cytomorphological features involving uniformity of staining, cellular morphology, nuclear morphology, cellular staining, nuclear staining and presence of impurities. Comparisons were made between the two methods of fixation and statistically analysed using McNemar non-parametric test. Cells were evenly distributed in wet-fixed smears (n=38, 95%) compared to spray fixed smears (n=19, 47.5%). Wet-fixed smears showed lesser impurities (n=13, 32.5%) than spray fixed smears (n=27, 67.5%). However, other parameters such as cytological and nuclear morphology, staining of cytoplasm and nucleus were found to be not significant when compared between the two methods of fixation (p<0.05). The study shows that wet-fixed smears have better cellular distribution and relatively fewer impurities when compared to the spray fixed smears. The method of wet-fixed smears may be used as an alternative to spray fixed smears. A larger sample size may be required for further validation.

With the advancement of the transportation system and improvement in road conditions, the number of high-velocity accidents has also increased. Almost all of these reported cases involve individuals who had travelled in vehicles without adhering to personal protection standards and with rash driving. Injuries to the facial region can be profoundly disturbing and particularly in children. Parents find it very distressing to see their child in pain with a disfigured or injured face. It is difficult to manage such crying & sometimes uncontrollable children. The most commonlyinjuredfacialbonesareNasal,Zygomaticandthe Mandible. The incidence of facial bone fracture in children is uncommon, and we present a case report of an18-month old child with a history of road traffic accident and swelling on the right side of the face. Intraoral examination shows limited mouth opening with submucosal ecchymosis in the right buccal mucosa and based on clinical and computed tomographic scan working diagnosis of fracture in the right body of the mandible was arrived. The child was treated with the circum-mandibular wiring to stabilize the mandibular fracture under general anaesthesia. After three weeks the splint was removed. The injury healed without complications in the post-operativeperiod.

Micro RNAs In Periodontal Disease – A Review

Mekha Grace Varghese ; Thomas George Valliaveettil ; Annie Kitty George ; Saranya Rajan

Annals of Dentistry.2020;27(1):11-21. doi:10.22452/adum.vol27no3

microRNAs (miRNAs) constitute a family of small, non-coding RNA molecules that regulate gene expression and protein expression. microRNAs have influence on a broad range of physiologic and pathologic conditions. They are also considered as promising biomarkers especially when they are secreted extracellularly. In the inflammatory pathways, they dysregulate the molecular processes and contribute to the development of chronic inflammatory diseases including periodontitis. In this review, we provide an overview of miRNA characteristics, biogenesis, mechanisms of action and profiling methods. In addition, the role of miRNAs in the pathobiology of periodontitis, especially those pertaining to the cellular and molecular pathways of inflammation has been considered to enhance our understanding of the pathobiology of periodontitis.

Annals of Dentistry.2020;27(1):22-27. doi:10.22452/adum.vol27no4

Resin Bonded Fixed Partial Denture (RBPFD) is a popular treatment for tooth preservation. Mechanical retention is a problem for RBFPD, where debonding is the main cause of failure. RBFPD preparation is minimal invasive. It removes undercut and tooth structure that supports retention so that single insertion guide can be achieved. This preparation was achieved by using surveyor on diagnostic cast, but there was a concern how to copy the surveyed cast to intraoral. Resin template method as a preparation guide was useful to avoid excessive tooth removal. RBFPD design was marked by using pencil on the diagnostic cast. The cast was surveyed to get the preparation designed and prepared by using milling device surveyor and burs. The template was made on the cast. Separator was applied and resin template was built along the margin until the occlusal line angle. The abutment teeth were etched and bonded. Bonding procedure was done on template. The template was placed on the teeth and polimerized. Abutment teeth preparation were done according to the cast with the bur contact simultaneously with the template’s margin and finishing line. Resin template has better accuration and adaptation, easier made and efficient, also prevent excessive tooth removal and control the preparation, mechanical retention can be achieved for RBFPD restoration longevity. Resin template is useful because preparation can be transfered from diagnostic cast to intraoral accurately.

Pilomatrixoma is an uncommon benign tumour arising from the matrix and inner sheath of a normal hair follicle as well as hair cortex. It is usually presented as a superficial, solitary, firm mass which is asymptomatic and slowly growing. It accounts for about 0.2% of all routine skin specimens and may poses a diagnostic challenge as it may resemble other common benign lesions found in the head and neck region. We report a case of a 33-year old men presented to us with a pilomatrixoma of the right cheek, surgical management and histological findings.

Natural products have demonstrated various activities beneficial to general health. Flaxseed (Linum usitatissimum) has been reported in many studies for its antimicrobial, antioxidant, and anti-inflammatory effects. Additionally, flaxseed extracts have skin wound healing activity and potential for treating oral ulcers. L. usitatissimum was extracted using 70% ethanol via soxhlet method and gas chromatography mass spectrum (GCMS) was used to analyze the components of L. usitatissimum extract. The crude flaxseed oil were applied to human oral fibroblasts (HOrF), and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was used to assess the cell viability after 24, 48 and 72 hours. Scratched HOrF cells were treated with crude flaxseed oil and healing was monitored per wound healing assay. GC-MS indicate that the major components present in L. usitatissimum oil extract are linolic, palmitic and oleic acid. L. usitatissimum crude oil extract showed high proliferation effect on HOrF cells at 24 and 48 hours, while the highest proliferation effect was recorded at 72 hours post-treatment. The wound healing assay results showed that healing activity of HOrF cells occurred as soon as 18 hours post-treatment when treated with L. usitatissimum crude oil extract. L. usitatissimum crude oil extract has proliferating and healing effects on HOrF cell line. Therefore, it can be considered as a potential promising oral wound healing agent.

Rare Morphology of The Third Maxillary Molar and Potential Complications in its Extraction

Siti Mazlipah Ismail ; Firdaus Hariri

Annals of Dentistry.2020;27(1):66-68. doi:10.22452/adum.vol27no10

There is a wide variation in the morphology of third maxillary molar which can be difficult to be identified radiographically. We present a case of a 26 year-old Yemeni female patient presented with difficult extraction of her left maxillary third molar. The extracted tooth showed a rare variation of root morphology, having four roots with three roots curving palatally at the apices. This report emphasized the potential complex morphological variation of maxillary third molar which may lead to the difficulty of a routine straight forward procedure thus needing careful extraction maneuvering to prevent any complications.
