Introduction: Aim of the study was to examine the occurrence of kissing molars from the nationwide Health 2000 Survey carried out on the Finnish adult population aged 30 years and older. Kissing molars refer to impaction of a mandibular third molar and a neighboring molar with occlusal surfaces facing towards each other. At present, prevalence of kissing molars at a national level is unknown. Methods and materials: From the two-staged stratified cluster-sample of 8028 subjects, panoramic radiographs and clinical oral examinations were carried out for 5989 subjects (46% men, 54% women; mean age 52.5 years; SD 14.6; range 30‒97). Radiographs were examined for presence of third molars and kissing molars. Clinical measurements included total number of clinically visible teeth and total number of molars. From the demographic data, age, gender, place of residence, and level of education were included. Statistical significances were evaluated with Fisher’s exact test and Mann-Whitney U test. SAS Callable SUDAAN software was used to obtain weighted distributions of kissing molars representative of the population aged 30 years and older, and separately of people with third molars. Results: Kissing molars occurred in 0.05% of the adult population (5 per 10000 adult inhabitants) and in 0.1% of those subjects with third molars (10 per 10000 such subjects). In subjects with kissing molars, the mean numbers of clinically visible teeth (p = 0.021) and molars (p = 0.016) were smaller compared to those without kissing molars. The demographic features analyzed, showed no statistically significant association with the occurrence of kissing molars. Conclusion: This is the first study published to date on the prevalence of kissing molars at the population level. The prevalence of kissing molars in the population was very small. For the sake of comparison, kissing molars are not seen as often as supernumerary teeth in third molar region.

Treatment of periodontal diseases is becoming more prevalent and one of the treatment methods is to regenerate periodontal tissues. Over the period many biomaterials have been developed many of which are currently being used and more research is still in progress. Such a range of biomaterials choice makes it a challenging ordeal for Dentists to weigh the pros and cons of the popular biomaterials. This manuscript attempts to be a comprehensive document that discusses the merits and demerits of various biomaterials to aid in the decision making of biomaterial choice for periodontal disease treatments.

Age is one of the essential factors in establishing the identity of the person. It plays an important role in forensic medicine, clinical dentistry and archaeology. Age estimation is crucial in medico legal cases and importance in forensic medicine, not only for identifying deceased victims but also in connection with crimes and accidents. Age estimation of unknown human bodies is very important in the setting of a crime investigation as well as mass disaster. The age for the individual can be assessed as skeletal, morphological, secondary sex character and dental age.This paper reviews various dental age estimation methods that have been used by the scientist in order to help the identification of remains.

The growing aesthetic demands of patients have led to the development of different types of all-ceramic crowns. Y-TZP zirconia-based restorations with feldspathic ceramic guarantee more satisfaction in terms of mimicry and biocompatibility than the metal-ceramic crowns. However, the bond at the zirconia and veneered porcelain interface seems to be the weakest link in this type of restoration. Indeed, numerous cases of interfacial decohesion of the cosmetic ceramic have been reported. For this purpose, numerous scientific studies have been carried out to further explore and accurately describe the characteristics of the interface at these two ceramics in order to strengthen the bond of bilayered ceramics.

A good oral health education program starts from early ages, and the most important time to initiate this it is when the first permanent tooth (the first permanent molar) erupts, and it lies on a correct diet and hygiene habits, including a healthy diet, a correct brushing technique, and a preventive therapeutic approach. The beneficial effect of a preventive program is a good oral health and the therapeutic approach is the dental sealing. Of course it is important to motivate small patients to maintain a good oral health, through the correct use of oral hygiene products, individual brushing techniques, and good eating habits. The prevention programs and the children’s receptiveness in maintaining proper oral hygiene can improve the oral health. If there is good communication between the physician and the patient then we can talk about the triad: theoretical presentation, practical exercises and individual biofilm removal techniques, which are indispensable factors in achieving an appropriate oral health status. When dental education programs can’t provide the proper prophylaxis of caries lesion, especially at the occlusal surfaces of molars and premolars with deep and retentive pits and grooves, dental sealing is an ideal option.

Segmented Le Fort I osteotomy is a surgical procedure which allows the posterior segments to be repositioned more coronally to close an open bite, as well as correcting transverse discrepancies. The aim of this retrospective study was to assess the prevalence of injuries to teeth and surrounding hard tissues in patients who had undergone the Le Fort I osteotomy procedure with maxillary segmentation. In total, 101 patients were included according to predetermined criteria. Radiographs from the 6-month postoperative follow-up were reviewed in all patients. Complications such as root fractures, root resorptions, periodontal defects, sclerotic and osteolytic processes were noted. Intraoral periapical radiographs were primarily reviewed and where unavailable, panoramic radiographs were instead used. In addition, preoperative and postoperative radiographs up to 30 months were reviewed in patients with found radiographic changes at 6 months. In cases with root fracture, the medical record was reviewed in search of any additional treatment. Seven root fractures were noted in total. Only one tooth required replacement, in this case with a dental implant. Clinically significant complications to teeth adjacent to vertical osteotomies from the Le Fort I osteotomy with maxillary segmentation were uncommon.
节段Le Fort I截骨术是一种外科手术，它允许后节段在冠状位置重新定位以关闭开放的咬合，并纠正横向差异。本回顾性研究的目的是评估接受上颌分割Le Fort I截骨术的患者牙齿和周围硬组织损伤的发生率。根据预先确定的标准，共纳入101例患者。对所有患者术后6个月随访的x线片进行回顾。并发症如根骨折，根吸收，牙周缺损，硬化和溶骨过程被注意到。主要回顾了口内根尖周x线片，如果没有，则使用全景x线片代替。此外，对6个月时发现影像学改变的患者进行术前和术后30个月的x线片检查。在发生根骨折的病例中，审查了医疗记录，以寻找任何额外的治疗方法。共发现7根骨折。只有一颗牙齿需要更换，在这种情况下是种植牙。Le Fort I型上颌截骨术垂直截骨术相邻牙的临床并发症并不常见。

Already in the 1980s, the World Health Organization (WHO) has postulated to analyze in all medical fields differences between the sexes. But until now there is a disturbing lack of scientifically based and meaningful data over the whole area of gender dentistry – for prevention as well as for treatment. The aim of this study was to evaluate the actual situation described as an IS-analysis of literature review on the topic of gender dentistry with the subthemes periodontal disease and tooth decay in the leading medical databases (Medline, Embase, BIOSIS Previews, Your Journals@Ovid, The Cochrane Library). We discuss these on the basis of an evidence-based guideline. For periodontal diseases we found no clear trend. Some studies showed no gender difference, others showed a higher prevalence for women or a higher prevalence for men. At the juvenile periodontitis and the occurring bacteria of periodontitis there were conflicting results as well. No simple statement can be made with respect to tooth decay, too. Respective studies merely show age as an important item. Totally it has to be noted that the scientific validity of some studies is not without any doubt as they are conducted with a too low number of clinical trials. Several studies are more than 15 years old, therefor providing a serious gender specific treatment in dentistry, future studies must increasingly incorporate and intensively discuss gender specific aspects.
早在20世纪80年代，世界卫生组织(卫生组织)就已假定在所有医学领域分析两性之间的差异。但到目前为止，令人不安的是，在整个性别牙科领域，无论是预防还是治疗，都缺乏科学依据和有意义的数据。本研究的目的是评估主要医学数据库(Medline, Embase, BIOSIS Previews, Your Journals@Ovid, The Cochrane Library)中关于性别牙科的子主题牙周病和蛀牙的文献综述的is分析所描述的实际情况。我们在循证指南的基础上讨论这些问题。对于牙周病，我们没有发现明显的趋势。一些研究显示没有性别差异，另一些则显示女性或男性的患病率更高。在青少年牙周炎和发生的牙周炎细菌也有矛盾的结果。关于蛀牙也没有简单的说法。各自的研究仅仅表明年龄是一个重要的项目。必须指出的是，一些研究的科学有效性并非毫无疑问，因为它们是在临床试验数量太少的情况下进行的。有几项研究已经超过15年了，因此，为了在牙科中提供严肃的性别特异性治疗，未来的研究必须越来越多地纳入并深入讨论性别特异性方面。

Introduction: This study was conducted to find out different polishing techniques’ effects on different porcelain materials by using atomic force microscopy (AFM). Material and Methods: Samples were made from four different porcelain materials (VMK 95, Ceramco III, Matchmaker, Vitablocs Mark II). Nine groups (n = 5) were randomly formed from the samples of each ceramic and nine different polishing methods were applied on them. AFM was used to evaluate the external topography and roughness of dental porcelains. To analyze the results of the study ANOVA and Tukey test were used statistically ( = 0.05). Results: Within the porcelain groups Ceramco and Matchmaker had higher Ra values, however VMK 95 and Mark II had lower Ra values. However when the different polishing techniques were compared, Gl (.1110) and SlPg (.2295) were found to have the lowest Ra values and no statistical differences were found between these two techniques (p > .05). In addition, no differences were found between glazed samples (Gl) and after polishing with Sof-lex and Prisma Gloss (Sl-Pg). On the other hand polishing with Sl and Pg together (Sl-Pg) significantly decreases the surface area. Conclusions: There were statistically significance between the glazed and the other specimens. Different polishing methods influenced the surface topography of different porcelains significantly ( p < .001).
