Cross bite merupakan kondisi dimana satu gigi atau lebih mengalami malposisi ke arah bukal atau lingual atau labial terhadap gigi antagonisnya. Cross bite dapat terjadi pada gigi anterior maupun posterior. Cross bite posterior dapat terjadi sebagai akibat kurangnya koordinasi dimensi lateral antara lengkung gigi rahang atas dan rahang bawah. Cross bite posterior dapat terjadi secara bilateral atau 2 sisi maupun unilateral atau 1 sisi. Berbagai penyebab cross bite posterior unilateral diantaranya adanya malposisi gigi ke lingual pada gigi rahang atas, adanya kebiasaan buruk seperti bertopang dagu satu sisi dan adanya pengaruh deviasi mandibula ketika menutup mulut. Tujuan artikel ini adalah menyajikan perawatan ortodontik cross bite posterior unilateral dengan teknik Begg. Pasien perempuan umur 19 tahun mengeluhkan gigi-gigi depan serta belakang atas dan bawah berjejal dan tidak nyaman untuk mengunyah. Diagnosis kasus adalah maloklusi Angle klas I, hubungan skeletal klas I dengan protrusif bimaksilar, protrusif bidental, crowding gigi anterior atas dan bawah, crowding gigi posterior atas kiri, edge to edge bite pada beberapa gigi anterior, cross bite antara gigi 22 dan 32, cross bite posterior unilateral pada sisi kanan, pergeseran rahang bawah kearah kiri, serta pergeseran midline gigi rahang bawah dan rahang atas kearah kiri.  Pasien dirawat menggunakan alat cekat teknik Begg. Koreksi cross bite dilakukan dengan ekspansi 1 sisi pada rahang atas kanan serta dengan pemasangan cross elastic untuk menarik gigi posterior bawah yang berada di luar lengkung. Setelah perawatan selama 11 bulan, cross bite posterior pada sisi kanan terkoreksi.   ABSTRACT: Unilateral posterior cross bite treatment using fixed orthodontic Begg appliance technique. Cross bite is a condition where one or more teeth may be abnormally malposed buccally or lingually or labially with reference to the opposing tooth or teeth. Cross bite can be classified based on location as anterior and posterior cross bite. Posterior cross bite occurs as result of lack of coordination in the lateral dimension between the upper and the lower arches. Posterior Cross bite can be unilateral involving one side of arch or bilateral which involves both sides. Posterior cross bite can be occur as result of a number of causes such us lingual positioning of upper tooth, presence of one side chin propped habit and presence of occlusal interferences can result in deviation of the mandible during jaw closure. The purpose of this articles to present unilateral posterior cross bite correction using Begg technique A 19 years old female patient complained of upper, lower front and back teeth crowded and uncomfortable for mastication. Diagnosis are malocclusion Angle Class I, Class I skeletal relationship with bimaksilar protrusive, upper and lower incisor retrusive, upper and lower anterior teeth crowding, upper left posterior teeth crowding, anterior edge to edge bite on several anterior tooth, anterior cross bite on 22 and 32, unilateral posterior cross bite on right side, shift to the left of mandible, shift to the left of the median line maxilla and mandible, The patien treated with fixed appliance Begg technique. One side expansion of maxilla on right side and posterior cross elastic are used to correct posterior cross bite. After 11 months of treatment, unilateral posterior cross bite on right side corrected.

OBJECTIVE: to analyze the pattern of disocclusion during excursive mandibular movements and presence or absence of occlusal interferences and occlusal pathologies (gingival recession and abfraction). METHOD: examination of 120 individuals divided into two groups, as follows: Group 1 - 90 patients with complete cleft lip and palate (study group), subdivided into 30 patients with complete left unilateral cleft lip and palate, 30 patients with complete right unilateral cleft lip and palate and 30 patients with complete bilateral cleft lip and palate; Group 2 - 30 individuals without clefts (control group). RESULTS: 58.8% of patients in Group 1 presented unilateral or bilateral canine guidance, 26.6% presented unilateral or bilateral group function and 54.4% presented lateral movements through the posterior teeth. Regarding protrusive movements, 80% presented anterior guidance and 20% presented posterior guidance. In Group 2, 69.6% of individuals presented unilateral or bilateral canine guidance, 43.2% presented unilateral or bilateral group function and only 13.3% presented lateral movements through the posterior teeth; 3.4% presented protrusion through the posterior teeth. CONCLUSIONS: there was no difference in the pattern of disocclusion between subgroups of patients with clefts. Group 2 presented predominance of bilateral group function, whereas Group 1 presented a higher prevalence of posterior guidance during lateral movements. Protrusion occurred primarily through anterior guidance in Group 2 and through the posterior teeth in Group 1. There was high prevalence of occlusal interferences at the molar area for both groups, yet with no correlation with occlusal pathologies (recession and abfraction).

The literature reports several materials for the restoration of endodontically treated teeth, with coronal destruction that requires an intra-root fiber post to stabilize the prosthetic part. The intra-radicular post of composite resin reinforced with fiberglass can be used as retainers in rehabilitating endodontically treated teeth due to their adhesiveness, pleasing aesthetics, and elasticity module close to the dentin less wear on the remaining structure. This clinical case reports the step-by-step application of dual resin cement (Rebilda DC Dentine - Voco) used as the cementation material of the post and material for the filling core in a single step, in an upper right lateral incisor. Moreover, it describes the advantages and indications of the post-and-core technique, also called “monobloc” which can be used in both anterior and posterior teeth. This protocol minimizes the adhesive interfaces, the chair time, and the steps of the clinical procedure.

Rapid Maxillary expansion or palatal expansion as it is sometimes called, occupies unique niche in dentofacial therapy. Rapid Maxillary expansion (RME) is a skeletal type of expansion that involves the separation of the mid-palatal suture and movement of the maxillary shelves away from each other. RME effects the maxillary complex, palatal vaults, maxillary anterior and posterior teeth, adjacent periodontal structures to bring about an expansion in the maxillary arch. Morphogenesis and anatomical features of the upper jaw determine the choice of the method of rapid palatal expansion with narrowing of the upper dentition, as an effective method for eliminating congenital deformities of the maxillofacial region. The majority of dental transverse measurements changed significantly as a result of RME. The maturity of the maxillofacial structures determines the timing and degree of success of rapid palatal dilatation treatment.

Relevance. To study the incidence of different types of resorption of multirooted primary teeth, to specify indications for deciduous molar extraction to prevent eruption abnormalities of permanent posterior teeth in mixed dentition.Materials and methods. Root resorption of 375 multirooted primary teeth (166 first primary molars and 209 second primary molars) was studied on panoramic X-rays of 60 children (30 girls and 30 boys) aged between 7 and 15. Illustrated classification by T.F. Vinogradova (1967) improved by authors was used to determine type and degree of root resorption of multi-rooted primary teeth. Received data were described with absolute values of number of cases and percentage. Chi-square was used to detect differences in sign incidence rate between groups, p<0.05 was considered statistically significant.Results. There were no statistically significant gender differences (p>0,05) in type and degree of root resorption of multirooted primary teeth. Type A resorption prevailed and constituted 53.3% of all primary molars. Disturbances in root resorption of multirooted primary teeth in mixed dentition were related to health condition of primary teeth. Transition of even resorption to unven was considered a risk factor of delayed eruption and aberrant position of permanent teeth, and indication for extraction of a primary molar in question. Conclusions. 1) Even root resorption (type A) was detected in 53.3% of primary molars in mixed dentition by orthopantomography. 2) Transition from even resorption of primary molar roots to uneven resorption was associated with eruption deviations and delayed premolar eruption. 3) Timely extraction of primary molars with uneven root resorption facilitated correct eruption of premolars and increased effectiveness of secondary prevention of malocclusion in children.

Abstract Objective To compare the effectiveness and complications of intraligamentary anesthesia (ILA) with conventional inferior alveolar nerve block (IANB) during injection and dental treatment of mandibular posterior teeth. Materials and methods In this randomized, prospective clinical trial, 72 patients (39 males, 33 females), scheduled for dental treatment of mandibular posterior teeth, were randomly allocated to ILA group (n = 35) received ILA injection or IANB group (n = 37) received the conventional IANB. Our primary outcome was to assess pain and stress (discomfort) during the injection and dental treatment, using the numeric rating scale (NRS) from 0 to 10 (0 = no pain, 10= the worst pain imaginable), whereas recording 24-h postoperative complications was our secondary outcomes. Results Patients in ILA group reported significantly less pain during injection when compared with IANB group (p = 0.03), while pain during dental treatment was similar in both groups (p = 0.2). Patients in both groups also reported similar law values of discomfort during treatment (p = 0.7). Although no signs of nerve contact or any other postoperative complications were observed, five patients in IANB group (none in ILA group) reported temporary irritations. Conclusion This study showed equivalent effectiveness of both intraligamentary anesthesia and conventional inferior alveolar nerve block, for pain control during routine dental treatment of mandibular posterior teeth. Nevertheless, ILA showed significantly less pain during injection. No major postoperative complications in both groups were observed. Clinical relevance ILA could be considered as an effective alternative for routine dental treatment. Trial registration NCT04563351

Bite turbos are a relatively new but widespread fabrication used in a variety of orthodontic cases. Bite turbos placed on lingual surfaces of upper incisors help disclude the posterior teeth and open the bite. This report describes a simple, effective, and economical technique to fabricate resin composite bite turbos. This method does not require laboratory procedures and can be manufactured using materials that are usually available in a regular dental practice.
